Title: Automatic adjuster incorporating wheel cylinder
Inventor: IKEGAMI HIROSHI
IPC: F16D65/56
Filed: 1989-09-21
Abstract: PURPOSE:To maintain space of a normal shoe and avoid drag phenomenon by increasing the amount of adjustment at the time of braking operation when shoe space becomes larger than the normal shoe space and at the time of braking release when the former becomes smaller than the latter so that automatic adjustment to normal space is done. CONSTITUTION:When shoe space is larger than normal shoe space, an adjuster screw 13 screws out gradually in accordance with braking operation to make shoe space approach normal shoe space. When shoe space is smaller than a backlash of a reversible screw 30, the adjuster screw 13 does not protrude at the time of go-stroke of a first piston 2, and only enters at the time of return- stroke of the first piston 2. Consequently, the adjuster screw 13 screw in gradually every time when braking is released, making shoe space approach normal shoe space.

Title: Semiconductor logic circuit
Inventor: SHIMOKAWA TAKEHISA
IPC: H03K19/0175
Filed: 1989-09-19
Abstract: PURPOSE:To prevent mis-judgment of a logic level by adopting a threshold voltage lower than an intermediate point level between a high level and a low level of an input signal when the input signal is at a high level and adopting a threshold voltage higher than the intermediate point level when the input signal is at a low level. CONSTITUTION:When an input signal IN is at a high level, an output signal C goes to a high level (nearly power supply voltage VCC) and an output signal inverse of C goes to a low level (nearly power supply voltage VEE). MOS transistors(TRs) MN5, MP5 are turned on by the output signals C, inverse of C and MOS TRs MN6, MP6 are turned off, a switch circuit 41 is turned on and a switch circuit 42 is turned off, then a reference voltage VRL lower than the intermediate point level is fed to an input buffer circuit 1 via the switch circuit 41 and the bipolar TR Q6 as a threshold voltage VR. Conversely, when the input signal IN is at a low level, a reference voltage VRH higher than the intermediate point level is fed to the input buffer circuit 1 a threshold voltage VR. Thus, mis-judgment of a logic level is prevented.

Title: Treatment of fly ash
Inventor: YOSHIDA HIROHISA
IPC: F23G7/00
Filed: 1988-09-30
Abstract: PURPOSE:To make fly ash usable as a cement material, construction material, aggregate, etc., by converting fly ash into ultrafine granules containing <=1wt.% of unburned fraction. CONSTITUTION:Fly ash is ashed at temperature below its melting point but above the ashing temperature for the unburned fraction until the content of said unburned fraction falls at 1wt.% followed by pulverization into ultrafine granules <= several microns in size. Alternately, fly ash is similarly pulverized into ultrafine granules which are, like the above-mentioned manner, ashed until the content of unburned fraction falls at 1wt.%. The mean granular size of limestone as a main raw material for cement is often several tens microns, the ultrafine fly ash <= several microns in size filling up the gap of the limestone, thus forming a closest packing. This effect will markedly improve the mechanical strength of cement.

Title: Hall element
Inventor: FUJII KANAE
IPC: G01R33/07
Filed: 1997-09-09
Abstract: PROBLEM TO BE SOLVED: To suppress imbalance in Hall voltage due to polarity of a power source, improve voltage linearity and enable highly accurate sensing, by providing two diffusion layers of an opposite conductive type to that of an active layer for limiting a current path at specific positions on the surface of the active layer. SOLUTION: Two gates 6a, 6b which are p-type diffusion layers are placed on a surface of an n-type active region 2 surrounded by current electrodes 4a, 4b, and sensing electrodes 5a, 5b are placed in point symmetry with respect to an intersection of a line passing through the center of the two current electrodes 4a, 4b, and a line passing through the center of the two sensing electrodes 5a, 5b. Thus, extension of a depletion layer due to built-in potential from the two gates 6a, 6b and a p-type Si substrate 1 is symmetric irrespective of polarity of input voltage to the current electrodes 4a, 4b. As a result, if absolute values of the input voltage are equal, input resistance is constant, so that imbalance in Hall voltage can be suppressed.

Title: Growth of organic substance whisker crystal
Inventor: SEKIGUCHI ATSUSHI
IPC: C30B29/62
Filed: 1992-09-14
Abstract: PURPOSE:To form a stitch-like thin film on the surface of a substrate and utilize the stitch-like thin film as an electric circuit by reacting a raw material organic substance fed into a space on the front surface of the substrate for the growth of the whisker in direction-selectivity to a metal pattern on the surface of the substrate. CONSTITUTION:The thin film of a metal (e.g. copper, zinc) is produced on a substrate (e.g. sapphire, silicon) to form the pattern of the metal thin film. An organic substance of raw material (e.g. 1,2-dicyanobenzene) is fed into a space on the front surface of the patterned metal thin film-adhered substrate. The organic substance of raw material is reacted on the surface of the substrate and/or in the space on the front surface of the substrate. Thus, whiskers grow in direction-selectivity to the metal pattern on the surface of the substrate.

IPC: H01L33/60
Filed: 1991-08-29
Abstract: PURPOSE:To provide an LED display device in which the peeling-off/ disconnection of the LED chip due to the shrinkage stress in a resin covering layer is eliminated. CONSTITUTION:An LED chip is mounted fixed by on the recessed part 10 of a substrate 1 and through-holes 12 are provided on the periphery of the chip 2 mounting part, i.e., in the substrate 1 in a manner that the part 10 is surrounded by them. A resin covering layer 3 has a back face layer 32 which is formed projecting from the back face of the substrate 1. The layer 32 is formed as one body together with the layer 3 on the surface of the substrate 1 by means of the substrate through-holes 12. Thanks to such structure, even when the shrinkage stress is generated on the layer 3, the force will apply in the direction that the LED chip is held to the substrate 1, and thereby no peeling-off/disconnection of the chip 2 from the part 10 nor separation between the substrate 1 and layer 3 will occur at all.

Title: Gas laser device
Inventor: NOZUE YASUHIRO
IPC: H01S3/036
Filed: 1986-10-17
Abstract: PURPOSE:To prevent the lowering of an output from a laser and the shortening of the life of a gas circulating in a laser tube by mounting a turbulent flow plate into the laser tube and agitating the gas while forcibly flowing the gas through a heat exchanger. CONSTITUTION:A laser medium gas is passed through a discharge section 1 generated between a pair of electrodes disposed into a laser tube 4, thus exciting the gas, then generating laser oscillation. The fatigued and deteriorated gas after discharge is diverted when it passes through turbulent flow plates 5. The laser medium gas is separated into three directions, and one part flows along the wall surface of the laser tube, the other one part in the direction of heat exchangers 2 and the remainder toward approximately the central section of the laser tube. The turbulent flow plates 5 have length sufficient for covering a discharge region by a pair of discharge electrodes fitted in the longitudinal direction of the laser tube 4, and are fixed onto the inner wall section of the laser tube 4 immediately after the gas passes through the discharge section 1 regarding a gas flow. Accordingly, the lowering of an output from a laser and the shortening of the life of the gas can be prevented.
