Title: Manufacture of high purity metal
Inventor: KOBANAWA YOSHIKO
IPC: C22B34/12
Filed: 1988-03-25
Abstract: PURPOSE:To manufacture high purity metal suitable to the electrode of a large- scale integrated circuit and the material for wiring by combining a halide decomposing method and electrotransport. CONSTITUTION:Material Ti 6 consisting of sponge titanium and iodine 7 are charged, e.g., into a reactor 1 made of Hastelloy-B and the reactor is thereafter subjected to evacuation. A filament 3 made of Ti disposed in the center of the reactor 1 is then directly subjected to electric conduction heating from a DC electric power source 5 through electric supplying jigs 4a and 4b to heat the filament to about >=1,400 deg.C. The entire reactor 1 is charged to a longitudinal furnace 2 heated to about 450 deg.C and is retained for about 200h. In this way, Ti is deposited on the filament 3. High purity Ti obtd. by this method shows extremely high purity on the side of a cathode and is suitable for the manufacture of high purity titanium silicide.

Title: Steering angle neutral position detection device
Inventor: OZAWA HIROMASA
IPC: B62D3/12
Filed: 1991-04-02
Abstract: PURPOSE:To enable a neutral position of steering to be confirmed with a simple operation by detecting a pin which protrudes at a neutral position of a rack with a detection means when rotating to the neutral position of the steering. CONSTITUTION:For detecting a position of a pin 8 which protrudes at a neutral position of a rack 2, a photo interrupter 9 is placed at a central position of a cover 4 and a light-emitting portion 9a and a light-reception portion 9b are provided so that the pin 8 may be sandwiched from the front and rear. When the rack 2 is being slid to the left or to the right by steering operation using the steering, light from the light-emitting portion 9a enters the light-receiving portion 9b, thus resulting in a non-neutral position of steering. Therefore, by rotating the steering to the right or to the left for returning the steering to the neutral position, light to the light-receiving portion 9b is interrupted by the pin 8 and the neutral position of the steering is detected at this point. Reporting of the neutral position of this steering to an operator may be confirmed for example by an alarm buzzer or lighting of a display lamp.

Title: Power supply device
Inventor: HONNA TAKAO
IPC: G05F1/59
Filed: 1983-04-22
Abstract: PURPOSE:To back up sufficiently the power supply even if one power supply device is faulty, by providing diodes in output ends of power supply devices which supply power to plural divided loads and supplying power to individual loads through diodes. CONSTITUTION:Diodes D1 and D2 are provided between constant voltage element VAD1 and VAD2. When a power supply signal VACBB is led, the element VAD2 is turned on through a logic INH1 by an output SL1 to lead out a signal VDC2 after the signal VACBB passes a logic INH2 and is counted by a timer TD1. An overcurrent relay OCR1 determines the capacity of the element VAD2 in a circuit VSB as the same value as a maximum value of power supply devices VS11-VSnn normally to cover one of devices VS11-VSnn. If plural devices are faulty, an output SL1 of the logic INH1 forming a self-holding is set to zero by an output SO1 of the relay OCR1. Then, the element VAD2 is turned off to eliminate the unstable output of the signal VDC2 due to overcurrent, and thus, operations of circuits L1-Ln are kept stable.

IPC: G06T7/60
Filed: 1989-03-22
Abstract: PURPOSE:To suppress a working buffer, to eliminate a check on a work for picture elements outside and objective range, and to shorten the processing time by eliminating the picture elements outside the range of the objects on a specific condition after a square is determined. CONSTITUTION:In a maximal square encoding system, in which the maximal square is determined in the working buffer while binary picture data are being inputted at every row, and the determined maximal square is stored into the other buffer memory, when the number of intervals of the picture elements on the side of the square in the picture element range is set at (w), the integrated value of the picture elements on the right side of the square is set at hr, the integrated value of the picture elements on the left side is set at hl, and maximum value among (w), hl and hr is set at (m), the black picture elements of the square are eliminated from the working buffer to the outside of the objective range on the specific condition such as a processing A to eliminate the other picture elements of the square excluding the (m) picture elements on the lower side of the square. Thus the working buffer can be reduced.

Title: Fm receiver
Inventor: IDOKAWA KAZUHIRO
IPC: H04H40/72
Filed: 1990-03-20
Abstract: PURPOSE:To prevent sensitivity for detecting noise from being lowered by removing high area noise from a composite signal based on a high area noise component extracted from the output of an FM demodulator. CONSTITUTION:The signal of an FM demodulator 25 is applied to a high area active filter 20 composed of a high-pass filter 18 and a high-pass amplifier 19, and the high area noise component is extracted and inputted to a noise detection circuit 21. The noise detection circuit 21 compares a pulse noise level with a noise AGC level and when the pulse noise level exceeds a threshold level, a control signal is outputted to a monostable multivibrator 22 in the next step. In the monostable multivibrator 22, a gate driving pulse is generated and a gate is opened only for the operating time of the monostable multivibrator by driving a gate circuit 16 with the gate driving pulse so as to interrupt the signal. The gate driving pulse is simultaneously inputted to a gate circuit 23 for canceling pilot signal as well, and when the signal is interrupted, the pilot cancel signal is stopped being impressed. Thus, the detection sensitivity is prevented from being lowered.

Title: Manufacture of semiconductor device
Inventor: OBARA KEIJI
IPC: H01L29/78
Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To form a sidewall spacer having a desired width on the side wall of a gate electrode composed of a polycide film and, at the same time, to prevent the peeling off of a silicide film from a polycrystalline Si film. SOLUTION: After a nitride film 17 is formed on at least the surface of a WSix film 13 an SiO2 film 15 for side wall spacer is deposited by the low pressure CVD method using a TEOS(tetraethylorthosilicate) as a raw material. Therefore, the side-wall spacer can be formed in a desired width and, at the same time, the growth of an oxide film at the boundary between a polycrystalline Si film 12 and the WSix film 13, etc., can be prevented, because the nitride film 17 prevents the rapid reaction between the W in the WSix film 13 and the oxygen in the TEOS caused by the high temperature at the time of depositing the SiO2 film 15.

Title: Belt for power transmission
Inventor: MISHIMA KYOICHI
IPC: F16G5/20
Filed: 1993-03-04
Abstract: PURPOSE:To prevent the abrasion of a belt and to avoid the generation of a slip, by projecting a part of an Aramid short fiber from a friction transmitter, and burying the short fibers to expose a part of a nonaramid short fiber on the side surface of the friction transmitter. CONSTITUTION:In a V-shaped rib 6, an Aramid short fiber 7 with an excellent antiabrasive property, and a nonaramid short fiber 8 whose antiabrasive property is less a little, are buried by maintaining the orientation in the width direction. A part of the Aramid short fiber 7 is projected a little from both side surfaces of the friction transmitter of the V-shaped rib 6, while the nonaramid short fiber 8 is buried to expose a part of the short fiber 8 on the end face of the short fiber of the single plane form, on both side surfaces of the v-shaped rib 6. Since there are the projections of the Aramid short fiber at the V-shaped groove wall surface of a pulley, and the V-shaped rib 6 side surface of the belt, immediately after the installing when the tensile force of the belt is high, the generation of the abrasion of the V-shaped rib 6 of the belt is suppressed. And after a long period of running of the belt, the projections of the Aramid short fiber 7 are cut off, and the cutting ends of the short fiber are exposed to the side surface of the V-shaped rib 6. As a result, the generation of a slip is also suppressed.
