Japan Telecom invented power generation shoes

Japanese telecom giant NTT invented a new shoe that allows people to walk and charge a cell phone, iPod, and other electronics at the same times.

This water-filled soles of shoes connected with a small generator . While walking , The pressure that the soles beared can make the generators produce about 1.2 watts of power. He said that the electricity generated by keeping moving on and on is enough to allow the iPod music player to operate uninterrupted.

In addition, the company is trying to study on how to increase power generation up to 3 watts.This power just is general mobile phones's need .

Although the shoes that do not have the storage function, but as long as the users of mobile phones will link up with the shoes and keep walking, the phone can automatically charge can be used directly.

NTT hopes in 2010 the new generation of shoes will formal launch

An X-Ray Machine Energized by Adhesive Tape


It may sound bizarre—or like some kind of high school science fair project, but it's not: Researchers have discovered that peeling adhesive tape ejects enough radiation to take an x-ray image. If they stick, the findings could set the stage for a less expensive x-ray machine that does not require electricity.

Lead researcher Carlos Camara, a physicist at the University of California, Los Angeles, reports in Nature today that his team captured x-rays of a finger on film (positioned behind it) by using a simple tape-peeling device (placed in front of it).

How is that possible? It turns out that radiation is released when tape is ripped from a surface. The reason, says Camara: electrons (negatively charged atomic particles) leap from a surface (peeling off of glass or aluminum works, too) to the adhesive side of a freshly yanked strip of tape, traveling so fast that they give off radiation, or energy, when they slam into it.

The result of this process when recorded by radiographic film is a fuzzy x-ray of the finger bone of physicist Seth Putterman, who runs the lab in which it was made.

"We have high hopes that this can be a very inexpensive alternative source of x-rays good enough to take x-ray images," Camara tells ScientificAmerican.com.

Conventional x-ray machines require expensive electrical components to create a beam of high-energy electrons that is aimed at a metal target. Camara envisions an x-ray device in which the adhesive tape could be peeled by a hand crank—and rolled back up for use again. He notes that researchers reused the same roll of tape many times without any change in x-ray quality. Unfortunately, he says, whether via the traditional method or the tacky one, it still requires the same amount of radiation to create an image.

Worried about radiation from the tape dispenser on your desk? Don't. In both a conventional and the experimental x-ray machine, electrons travel unhindered by air molecules through a vacuum chamber; that allows them to produce the higher energy needed to make x-rays. Normal air, comprised of nitrogen and oxygen and other gases, slows the electrons to a pace that is so sluggish there is only enough energy left to produce a faintly visible, benign blue light.

The maintenance of door hardware


Hardware is the soul of a whole door, including the handle, lock, hinge, and so on。They are so small, but playing an significant role.

The key to the life of door lies in the maintenance of hardware. Stainless steel handle and other Stainless steel hardware can be polished with stainless steel cleaner, in order to make it glossy. During the long time movement, the performance of hinge, hanging wheel , castor and other moving parts may be lower ,owing to the dust adhesion. One or two drops of lubricating oil every six months can maintain its smooth. If the rotation of the lock insert is not flexible enough, can use knife to scrape black powder from pencil core and blowing it into the keyhole. This is because the composition of graphite is a very good solid lubricant. But to be sure to avoid Lubricating Oil, because this would be more easier to adhere dust.

Special attention should be paid to the rotating direction of the handle , avoiding with all one's strength. In particular, it is necessary to educate children, not hanging in the door handles dangling, because it is very dangerous and may be prone to internal damage to the door.

The introduction of Cryonetic machining

Cryonetic machining is a mechanical working process employing the special properties of materials in low/ultra-low temperature condition.

In the low-temperature machining, the use of ultra-low-temperature liquid fluid in the machining system, cutting the area to form local low-temperature (or ultra-low temperature), in order to take advantage of this state object processing and processing tools to change the mechanical properties, so that it is conducive to machining. It can form a better state of processing,especially for some of materials that hard to process,such as titanium alloys, low-alloy steel, low carbon mild steel and particularly some of the toughness of plastic composite materials.

The basic steps of cryonetic machining:

① According to the processing and object processing tool set features the best low-temperature processing temperature Topt;

② the use of low-temperature fluid so that the specific area of closed-end processing temperature Topt;

③ automatic injection of the cryogenic fluid in order to maintain the temperature of processing zones in the state of Topt: On the one hand, when detected in the processing zone temperature deviation Topt, through feedback controller to regulate the flow jet, on the other hand, when the input power processing system Changes directly through the feed-forward regulation of jet traffic controllers in advance in order to maintain the best state of low-temperature processing.

All You Need to Know About Wines


Wine is nothing but a mixture of wild species of grapes, rice and different types of yeasts without the use of sugar, enzymes or any lactic acids. The word "wine" is a Latin word derived from indo-European countries.

Composition of wines: Wines consist of water to a large extent. In addition to this, wines also contain variety of acids such as lactic acids, ethyl acid, minerals such as iron, calcium, sodium, potassium, sulphates and vitamins such as vitamin A and vitamin P.

There exist different types of wines according to the base product, two of which are listed below:

1) Fruit wine: ex-apple, berries
2) Vegetable wine: ex- wheat, barley

The production of wines was first found in places of Georgia and Iraq at around 6000 BC to 5000 BC. Traces of wines were also found in Greece, ancient Europe.

Cultivation of wines was started in North East areas at around 3000 BC. Cultivation of red and white wine, as we know them today, first started in Egypt, but wide-scale cultivation of wines began in Rome, which produced the best quality wine. They produced different flavors of wine.

Dry wine is one of the most popular types of wines. During fermentation, when sugar is converted into alcohol, the toxic alcohol kills the yeast and the resulting wine is called as dry wine. Wines are mainly produced from the grape species known as Vitis vinifera.

There exist different types of wines like red wine, white wine etc. They are distinguished on the amount of sugar used and the time required for fermentation.

A few types of wines are listed below:

1) Vintage wines: In order to produce a vintage wine it is a must that at least 95% of the volume of grapes used, are produced in a single year. They are mostly produced in USA.

2) Non vintage wines: They are produced from vintage wines itself. In these, at least 50% of the grapes used should have been produced in the same year.

3) Organic wines: Organic wines are produced from grapes without the use of fertilizers and pesticides. They do not contain any harmful material and are used to cure a number of diseases.

4) Red wines: They are produced from black grapes and are red in color. It prevents cancer and heart diseases because of its anti-inflammatory properties.

5) White wine: They are produced from white grapes; and they are pale yellow in color.

When alcohol is added in a wine it is called as fortified wine. Taste of wines depends on the drinker's palate.

Vintage wines are costliest of all wines. They can cost thousands of dollars per bottle.

Some of the most expensive wines are Bordeaux and Cult wines.

Production:

France is the largest producer of wines. Italy is the second largest producer.

Italy is the largest exporter of wines.

Uses: Wine is the most popular beverage, and can also be used as a flavoring agent.

Wines also have a good effect on cardiovascular problems. Wines can also used for religious and ritual purposes.

Which Type of Coffee Machine Will Suit Your Business?

a) Traditional Espresso Machines

These machines incorporate the art and theatricality of coffee making, and therefore good barista training is essential to ensure a detailed knowledge of great coffee production. A barista is an expert at making espresso and a master of a variety of espresso based beverages. Once these skills have been mastered, a good barista can produce hundreds of drinks per day.Prices can vary from around £800 to £6000, but remember, you get what you pay for, so make sure that the machine you choose is new and fully warranted, including full barista training and a good support service. The great thing about traditional machines is that there are no major moving parts so less to go wrong.

b) Bean to Cup Machines

A bean to cup machine does exactly what it says! The fresh coffee beans are placed inside the machine and on the press of a button the machine automatically grinds the beans and pours both coffee and milk into your cup. The machine automatically heats and froths the milk to produce the perfect latte/cappuccino etc. The milk is usually kept in a fridge or milk chiller next to the machine; a pipe from the machine connects into the fridge and when the drink selection button is pressed the machine draws the milk from the fridge and sucks it into the machine steams, heats it and drops it into the cup. These various coffee machines are designed to produce anything from 50 cups per day to over 500 per day. The cost of these can vary from under £1000 to well over £10000, so it is important you make the correct choice.

c) Pod System

Similar to traditional, but you would usually only have 1 or 2 group versions and you wouldn’t need a grinder because you would use what are called pods. The advantages are that they are easy to use, producing good quality drink and nice aromas. The time taken to make the coffee is approximately the same as a traditional machine. The disadvantages are that they are more expensive per cup due to packaging cost. Typically a good quality pod will cost 20p per cup to produce. These machines will suit any small site and tend to be cheaper than the other machines, costing around £395 upwards.

d) Filter System and Bulk Brew System

These systems are for simply using filter coffee. A 2 jug filter makes great coffee for about 5 to 7 minutes, however if it’s left to stew for a while, as filter coffee usually is, the quality quickly deteriorates due to constant warming. Typically there can be waste, and so while the cup price is around 10p per cup, with waste, this could work out to be nearer 20p per cup. It can be used if there is a high demand for coffee over a short space of time such as serving 120 wedding guests after the dinner. A filter machine is always a back up to a traditional or bean to cup machine for use at very busy times or in case of a machine breakdown.Bulk brew systems are large scale filter systems used in locations such as banqueting facilities, hotels and sporting events. There are hundreds of different coffee machine systems available depending on how many litres of coffee need to be served and in what time scale.
