摘要:
A powder preparing device has a filtering device which processes CMP waste water and a vacuum dry-freezing device which dries a slurry which is concentrated to a high concentration by the filtering device. A membrane module in which at least one gel filtering film in which a gel layer is formed on a surface of a filtering membrane having a pore size of 0.25 μm is provided is placed within the filtering device. A pump sucks waste water from within the gel filtering membrane of the membrane module. The high-concentration slurry obtained by the filtering device may be supplied for various uses without further processing, or a powder may be obtained by transporting the high-concentration slurry to the vacuum dry-freezing device using a transporting pump and applying a drying process.

There is provided a hydrogen production apparatus having a simple structure for efficiently producing hydrogen. The hydrogen production apparatus 10 comprises a reactor 12 for reacting silicon (which may be waste silicon) and an aqueous basic hydroxide solution, a hydrogen absorbing alloy 20 for storing hydrogen produced by the reaction, and a reservoir/filter 14 which retains a solid or liquid product generated in the reactor 12 and filters a solution or suspension containing the solid or liquid product so as to separate the product from water.

In a plug and a receptacle of a microstrip line connector, the plug has a rectangular parallelpipedic insulating support block, a signal contact projecting upward from the center of the insulating support block and a pair of L-angle brackets projecting out upward from both ends of the insulating support block, the pair of brackets being connected to opposite ends of a coupling plate portion provided along the side wall surface of the insulating support block. The coupling plate portion has at the center of its lower marginal edge a recess formed astride a signal conductor of a microstrip line provided on a printed circuit board. The receptacle is made up of a rectangular parallelpipedic insulating housing having three contact housing rooms defined by two partition walls, a signal socket contact housed in the central contact housing room, a U-shaped ground socket contact having two contact portions housed in the side contact housing rooms, and a shield cover mounted on the insulating housing in a manner to cover almost all over its back and hold its top and bottom panel portions. The insulating housing has a contact introducing hole in its front panel portion centrally thereof and communicating with the central contact housing room, for receiving the signal contact of the mating plug. The insulating housing has slots in its side panel portions in the front-to-back direction and communicating with the side contact housing rooms, for receiving opposed edges of the pair of L-angle brackets.

A dynamic contour extracting means detects, using a dynamic contour extraction method generally known as SNAKE, a contour of a recognition object included on an image by the following steps: a curve with control points is disposed in an image; an internal energy Eint indicating smoothness of the curve, an image energy Eimage, and an external energy Eext are summed up; and the curve is modified so that the summed total energy becomes the minimum. Here, a template is stored for including disposition information of primary control points that are bound to be moved only in a vertical or horizontal direction based on a road shape. The dynamic contour extracting means moves the primary control points based on the template. The primary control points can be rapidly moved owing to their limited movement direction.

When display data for both odd-numbered and even-numbered scan electrodes in an electroluminescent display are both actuating data, the brightness of electroluminescent elements connected to the odd-numbered electrode is adjusted by adjusting the timing for starting the application of the actuating voltage and the brightness of electroluminescent elements connected to the even-numbered electrode is adjusted by adjusting the timing for terminating the application of the actuating voltage. Moreover, electric charge in the EL elements is retained by maintaining the application of the actuating voltages during scanning operations.

A device for forming a diamond film has a casing in which a vacuum is maintained to 50 Torr: a positive electrode and a negative electrode are disposed within the casing so that ends of the positive electrode and the negative electrode are opposed to each other through a space: a substrate is disposed near the space between the electrodes, a gas inlet pipe supplies a mixture gas of hydrogen, argon and methane to the space between the electrodes and an arc power supply is connected to the electrodes for supplying a predetermined arc output power thereacross to form an arc discharge column in the space therebetween. By supplying the mixture gas to the arc discharge column of which the temperature is extremely high, the mixture gas is decomposed at a high rate, and a diamond film of high purity grows on the substrate at a high speed.

A first heat treatment is carried out in which a material powder comprising magnesium is kept in the atmosphere of hydrogen gas and the temperature and pressure in the atmosphere of hydrogen gas are maintained in the temperature-pressure region in which single Mg and H2 coexist in a thermodynamically stable state, whereby the coating on the surface of the material powder is removed. Next, a second heat treatment is carried out in which the temperature and pressure in the atmosphere of hydrogen gas are changed and maintained in the temperature-pressure region in which MgH2 exists in a thermodynamically stable state. Hence, Mg from which the coating is removed reacts promptly with H2, and MgH2 is produced at high yield. Magnesium-based hydrides containing high purity MgH2 can thus be obtained by supplying energy less than that required for the related art that requires an activation treatment.

An ore containing crystal water (bond water) is heated to dehydrate the crystal water in the form of water vapor, thereby rendering the ore porous to generate a porous ore. Next, the porous ore is forced into contact with a dry-distilled gas (organic gas) obtained by dry-distillation of an organic substance such as wood and the like or an organic liquid such as tar and the like. An organic compound such as tar and the like contained in the dry-distilled gas or organic liquid adheres to the surface of the porous ore. Next, the porous ore adhered with an organic compound is heated at 500° C. or higher, to generate an ore in which a part of an oxide of an element such as iron and the like contained is reduced by carbon in the organic compound.
