Title: Manufacture of hydrogen storage battery
Inventor: MIZUNO TAKASHI
IPC: H01M4/26
Filed: 1989-03-24
Abstract: PURPOSE:To increase the capacity and discharge performance of a hydrogen storage electrode by mixing hydrogen storage alloy powder and binder powder, plating the mixture immediately or after crushing, then preparing pasty material for filling into a porous metal substrate. CONSTITUTION:A suitable amount of a fiber forming powdery binder such as PTFE is uniformly mixed with hydrogen storage alloy powder to form a porous mixture having many spaces between fibers. Electroless plating of conductive metal such as copper and nickel is conducted to this mixture immediately or after crushing. It is preferable that the surface of the binder is partially plated as well as the whole surface of the alloy and the total amount of plating is limited to 5-25% of the mixture. This mixture is added to a viscous solution such as CNC solution to form a pasty material, and it is filled in a porous metal substrate, then they are dried and baked to prepare a negative plate. Since conductivity and filled amount are increased, capacity can be increased.

Title: Choke coil
Inventor: HARADA TORU
IPC: H01F27/24
Filed: 1989-03-24
Abstract: PURPOSE:To obtain a choke coil characterized by high saturation magnetomotive force, less magnetic flux leakage and high permeability by inserting a spacer which is formed with a magnetic material whose permeability is lower than that of a core material and whose saturation magnetic flux density is higher than that of the core material into a gap. CONSTITUTION:In a choke coil A, a part of a toroidal core 1 which is formed with a high permeability magnetic material such as an amorphous material is cut out, and a gap 2 is provided. A spacer 3 comprising a magnetic material characterized by low permeability and high saturation magnetic flux density is inserted into the gas 2. A conductor wire 4 such as polyurethane coated copper wire and the like is wound around the core 1 many number of turns, and the coil is formed. When a large current is made to flow through the conductor wire 4 until the magnetic flux density in the core 1 is saturated, the choke coil having highly saturated magnetomotive force is obtained. As the gap 2, the magnetic material whose permeability is relatively low is used. In this way, the saturation magnetomotive force of the choke coil having the high permeability can be made high, and the leaking magnetic flux at the gap part is made less. Magnetic interference with surrounding electric parts can be suppressed.

Abstract: PURPOSE:To unnecessitate the correction of the form of product portions after mold clamping by a method wherein guide pin mounting holes are eccentrically bored in bushings on either one of a stationary mold and a movable mold and pin insertedly fitting holes are bored in bushings on the remaining mold. CONSTITUTION:The positional shiftings of bushing holes 51 and 61 are checked with reference to the forms of product portions 11 and 12 the state that a stationary mold 1 an a movable mold 2 are mounted on a setting press. Bushings 41 and 71 are mounted to a guide pin 15 according to the checked positional shift and the positions of the bushings 41 and 71 with respect to the guide pin 15 are fixed.

Title: Laser beam optical system
Inventor: SAKUMA NOBUO
IPC: H04N1/12
Filed: 1982-05-01
Abstract: PURPOSE:To compensate a fall of a rotary mirror, by using a cylindrical mirror lens which uses the plane side of a flat convex cylindrical lens to a reflector. CONSTITUTION:The plane of a flat convex cylindrical lens 6 is used as a reflecting surface, and a beam is made incident obliquely to the optical axis. Thus the optical path is folded by a reflecting surface and the beam focusing in the subscanning direction is performed simultaneously. The reflected light on the surface of the mirror lens 6 does not come back to a rotary polyhedral mirror as shown by dotted lines. This eliminates the generation of a static ghost and the flare. No dust nor toner is stacked since the lens surface is set downward. Then it is possible to use a cylindrical lens of a long para-axial focal distance owing to the fact that the beam is made incident obliquely to the lens 6. When a beam having 30 deg. inclination to the optical axis is made incident to the lens 6, the incident angle of the beam is set at 20.5 deg. to a photoreceptor. As a result, the ghost due to the reflected light scattered from the surface of the photoreceptor can be reduced.

Title: Information processor and its power consumption regulation method
Inventor: KURIHARA KAZUO
IPC: G06F3/16
Filed: 1999-03-18
Abstract: PROBLEM TO BE SOLVED: To make regulable the power consumption, to prevent the leakage of information and also, to improve the security of information by collating the user characteristic that is recognized by a characteristic recognition means with the previously stored user characteristic. SOLUTION: The power consumption mode of an information processor 22 is brought into a power saving mode if a user 21 does not operate the processor 22 for a fixed time. When the user 21 starts again his input operation in front of the processor 22 while the processor 22 is kept in the power saving mode, the user 21 utters voices to a voice recognizer 26 of the processor 22. Thus, the recognizer 26 detects the voices 25 of the user 21 and collates the voice information with the previously stored voices of the user 21. If the coincidence is decided between the detected voices 25 and the previously stored voices, the power consumption mode of the processor 22 is shifted to a normal mode to secure the normal power consumption with which the user 21 can perform his input operation.

Title: Treatment of muddy water
Inventor: OOWADA KENJI
IPC: B01D21/01
Filed: 1981-05-19
Abstract: PURPOSE: To accelerate separation of a solid component in muddy water and to enhance treating efficiency by a method wherein a mineral acid is added to muddy water to adjust the pH thereof to 3.5W5.0 and, after pH adjustment, a nonionic acrylic amide high molecular coagulant is added to precipitate and separate a solid component therein.  
     CONSTITUTION: When muddy water which contains about 10% bentonite and of which the total solid component is 45%, specific gravity is 1.39 and pH is 7.5 is allowed to stand, the solid component is not precipitated and, even if a coagulant is added thereto, coagulation is bad and the solid component is hardly separated. To 200ml of said muddy water, 2ml of 35% hydrochloric acid is added under stirring to adjust the pH to 3.5 and, thereafter, nonionic acrylic amide is added in an amount of 300ppm as a coagulant to be stirred. As the result, the solid component therein is precipitated within several min and the muddy water is separated into clear supernatant water and floc. This separated muddy water is easily filtered and, after filtering, filter cake is formed into a solid substance by merely pressing said cake by hand and this solid substance contains 36% water and is easily consolidated under pressure.
