Patent JP-H05315928-A (JP)
Title: Detection switch
Inventor: ISHIKAWA NOBUHARU
IPC: H03K17/78
Filed: 1992-05-13
Abstract: PURPOSE:To set the degree of allowance independently of the adjustment of hysteresis width by changing the range of hysteresis and independently forming a condition for setting up the degree of allowance. CONSTITUTION:A current I1 determined by a resistor R6 is allowed to flow into a transistor(TR) Q9. The constant current I1 is allowed to flow into TRs Q6 to Q8 by a current mirror and a constant current I2 is allowed to flow into TRs Q1 to Q5 by another current mirror. When there is no object and the output level of an amplifier circuit 6 is a low level, the output of a comparator is an 'H' level and a TR Q12 is ON. Thereby a current I3 flowing into a variable resistor R7 is allowed to flow into the TR Q12. The current I2 is changed by changing the resistance value of a variable resistor R2. Thereby the thresholds Vth1, Vth3 of comparators CMP1, CMP3 are changed respectively in the reversed directions at the same rate. In addition, hysteresis width alpha=R4XI3 can be changed by changing the resistance value of the R7 and the current I3.

Abstract: PURPOSE:To obtain a fuel concentration sensor having simple constitution and high sensitivity and reliability by forming at least a part of anode having a catalyst layer with a porous conductor, and undergoing electrochemical reaction in a mixture solution of fuel and electrolyte. CONSTITUTION:An anode 140 and a cathode 16 undergo electrochemical reaction in a mixture solution of liquid fuel and electrolyte of a fuel cell, and applying d, c, voltage between both electrodes by a power source 18, current is deteced in proportion to the fuel concentration in the mixture solution with a sensor 1. The anode 140 is formed with a porous plate-shaped conductor, and shows a permeation retarding function against liquid which tends to permeate from one side of the plate to the other side. A catalyst layer 19 which increases sensor sensitivity is formed on one side of the anode 140, and the outside of the layer 19 is sealed frmo the mixture solution with a sealing layer 200. The fuel concentration in the mixture solution is detected in high sensitivity through the anode having simple constitution and permeation retarding function.

Abstract: PURPOSE:To uniformly dry-etch a wafer by pressing an attaching the wafer to the surface of a lower electrode by a clamper and vertically moving an annular electrode around the lower electrode. CONSTITUTION:A wafer 7 is placed at the specified position of a lower electrode 4, and the wafer 7 is pressed on the upper surface 4a of the lower electrode 4 by the claw 10a of a clamper 10.

Meanwhile, since the wafer 7 is firmly attached to the lower electrode 4, the wafer 7 is indirectly and uniformly cooled, and the wafer 7 is not affected by heat deterioration in a mask.

Title: Multistage cluster rolling mill
Inventor: YAGISHITA KOTAROU
IPC: B21B13/14
Filed: 1981-09-21
Abstract: PURPOSE:To decrease the number of rolls and to provide simple construction by setting the number of backup rolls that support intermediate rolls at 1:1 and supporting the respective rolls by means of bearing chocks. CONSTITUTION:Work rolls 2a, 2b are of a small diameter and have virtually no elastic deflections because chocks 5a, 5b for backup rolls have high rigidity and shafts 13a, 13b have short spans, thus the work rolls are capable of high rolling-down rolling. Since the rolls 2a, 2b of a small diameter are supported from diagonally behind by means of respectively two pieces of intermediate rolls 3a, 3b, they have virtually no deflections against the forces in a horizontal direction owing to the tension of a plate material to be rolled. Since the respective rolls are supported by the chocks, respectively and have large movable extents in a vertical directions, the rate of adjusting the gap between the rolls 2a and 2b is large, the range of rollable thicknesses is wide and the changing of the rolls is easy.

Abstract: PURPOSE:To generate a uniform light signal through each shutter aperture part even when a liquid crystal cell is long-sized by providing a spacer near the shutter aperture part. CONSTITUTION:As liquid crystal 9 nematic liquid crystal which has positive dielectric anisotropy is used, so a common electrode 1 and a signal electrode 2 are applied with a voltage of >=20V to keep a light shield state all the time. This liquid crystal optical shutter is designed as a short shutter array having an array of shutter aperture parts 3. Therefore, about 2,000 shutter aperture parts 3 are formed. The voltage is applied between the upper and lower electrodes 1 and 2 in this mode to turn on and off the shutter aperture parts 3, but when the cell is long, the interval between upper and lower substrates 7 and 8, i.e. cell thickness should be uniform. For the purpose, spacers 11 and 11' are arranged near the shutter aperture parts 3, and thus the cell thickness of the liquid crystal cell is made uniform to uniform the transmittivity characteristics when all shutter aperture parts are open.
