Title: Force conversion mechanism
Inventor: KANEKO TATSURO
IPC: G01G3/12
Filed: 1991-05-13
Abstract: PURPOSE:To obtain a force conversion mechanism which generates little process error for each unit in mass production, and for which a pivot that is relatively easily manufactured at a low cost, is used. CONSTITUTION:A rectangular thin plate 6 is divided into three parts in series with two thin linkage parts 7, 7 left, and an arm 10 is fixed to a thin plate in the center, while a base 12 is fixed to thin plates on both ends. When a deformation gauge is fixed between the arm 10 and the base 12, for example, and a force F is added to one end of the arm 10, a force F' is transmitted to the other end, and a deformation gauge 5 is thus deformed.

Title: Video detecting circuit
Inventor: USUI AKIRA
IPC: H03D1/22
Filed: 1980-09-30
Abstract: PURPOSE: To reduce detection distortion by using a phase compenating circuit for  a video detecting circuit which uses a pseudo synchronous detecting circuit.  
     CONSTITUTION: An input signal is divided into two by fubber amplifiers 2 and 3 composed of transistors (TR)Q15 and Q16, and one component is applied to a multiplying circuit 6 through a carrier amplifier 5 having a synchronizing circuit 4 tuning with a video carrier and a limiter diode. The other signal component is amplified by a linear amplifier 7 and applied to the multiplying circuit 6. The multiplying circuit 6 detects both the signal components synchronously to output a video detection signal from an output terminal 8. At the front stage of the linear amplifier 7, on the other hand, the linear inverting amplifier 9a consisting of TRs Q17 and Q18 and resistances R13, R15, R14, and R16 is provided, and the phase delaying circuit 9b consisting of resistances R17 and R18 and capacitors C3 and C4 is connected to the emitters of TRs Q19 and Q20 connected to the collectors of the Trs Q17 and Q18 to cancel a phase difference between both the components.

Title: Pattern generator
Inventor: TANAKA SADAAKI
IPC: H03K5/156
Filed: 1985-06-24
Abstract: PURPOSE:To detect the abnormality generated in a pattern generating circuit easily and quickly by providing an auxiliary register to which inverted data of the most significant digit register is set and comparing the least significant digit data with just preceding data when pattern generation is terminated. CONSTITUTION:Input data is set to registers R1-Rn just before the start of test, and inverted data of the most significant digit register Rn is set to an auxiliary register 6. After the shift operation, that is, when pattern generation is terminated, contents of registers R1 and R2 do not coincide with each other because contents of registers 6 and Rn are set to registers R1 and R2. If optional one of registers R1-Rn is faulty, registers from this faulty register to the least significant digit register R1 have the same data when pattern generation is terminated. Thus, a signal indicating coincidence between contents of registers R1 and R2, namely, a trouble signal is outputted to an output terminal 5 of a disaccord detecting circuit 4.

Abstract: PURPOSE: To obtain a fiber-reactive formazan dye suitable for dyeing cotton in a high yield by saponifying a specified formazan compd. and reacting the obtained amino compd. with a triazine.  
     CONSTITUTION: An aminophenol of formula I (ring C may have other substituents) is diazotized and reacted with a coupling component of formula II (X is O, CO-O or SO 2 -O; rings A and B may have other substituents). Before, during or after the coupling reaction, a copper salt or a nickel salt is added. Then, the obtained formazan compd. of formula III (Me is copper or nickel; Kat +  is an equivalent of cation) is saponified and the obtained amino compd. is reacted with a triazine of formula IV or formula V (Y is a halogen; Z 1  is a 1-4C alkoxy, amino or the like).

Title: Drawing method of optical fiber cable
Inventor: KOUNOSU KOUZOU
IPC: G02B6/24
Filed: 1984-07-03
Abstract: PURPOSE:To make it possible to reutilize a drawn optical fiber cable by setting the angle, which is formed between a messanger wire which pulls the optical fiber cable and the stringing direction of an overhead earth wire, to a value within such range that a flexural lateral pressure exceeding an allowable value is not applied to the optical fiber cable. CONSTITUTION:The end part of an optical fiber cable 2 is taken out from the inside of an overhead earth wire 1 clamped on an iron tower 8 by an anchor metallic tool 11, and one end of a messanger wire 5 is connected to it through a connecting metallic tool 12, and the other end part is clipped by a caterpillar drawing device 6 to draw out the optical fiber cable 2. In this case, an angle alpha formed between the stringing direction of the overhead earth wire 1 and the messanger wire 5 is set to a considerably small value by arranging the caterpillar drawing device 6 apart from the iron rower 8. Since the angle alpha is very small, the angle of direction conversion of drawing is made smaller as the whole when the optical fiber cable 2 is guided by guide rolls. Thus, application of an excessive flexural lateral pressure is prevented.

Title: Method and device for cleaning printed board
Inventor: ISHIKAWA MITSUO
IPC: C23G5/02
Filed: 1989-06-01
Abstract: PURPOSE:To realize the cleaning method and the device of a printed board out of danger of burning and exposition by a method wherein the vapor of low boiling point halogenated hydrocarbon is made to float over a flammable cleaning agent at the same time when the cleaning agent is heated, a printed board is dipped into the cleaning agent and cleaned, and then the board is vapor-cleaned with halogenated hydrocarbon. CONSTITUTION:First of all, a halogenated hydrocarbon solvent 4 of low boiling point is heated by a heater 8. The solvent 4 starts vaporizing vigorously to fill a device main body 1 as its temperature comes close to its boiling point and returns to a solvent tank 5 when it turns into liquid as it comes in contact with a cooling tube 9. The solvent 4 in the tank 5 heats a cleaning agent 6 inside a cleaning agent tank 7 at a proper temperature through the intermediary of a partition wall 2. Then, a printed board P is dipped into the cleaning agent 6 of the tank 7. After being cleaned with the cleaning agent 6, the printed board P is vapor-cleaned in the vapor of the solvent 4. By this setup, as the topside of the flammable cleaning agent 6 is covered with the vapor of the non-flammable solvent 4, this cleaning method is free of the danger of explosion by ignition, so that safe and economical cleaning can be carried out.

Title: Manufacture of semiconductor device
Inventor: SHIBAYAMA HIKOSUKE
IPC: H01L21/316
Filed: 1978-11-08
Abstract: PURPOSE: To minimize bird peak by forming a silicon nitriding film via a silicon oxinitride film on a non-oxide region disposed on a Si substrate and thereafter selectively oxidizing the remaining portion.  
     CONSTITUTION: After providing a silicon oxinitride film 11 on a Si substrate 1, a Si 3 N 4  film 3 is formed thereon, and the remaining portion other than a non-oxide region is eliminated by etching. Subsequent to theremal oxidization, a thick SiO 2  film 4 is formed. A gate insulation film is formed by removing the Si 3 N 4  film 3 and the silicon oxinitride film 11. In this arrangement, since a silicon oxinitride film is interposed between the Si substrate and the acid-resistant Si 3 N 4  film, the distortion of Si 3 N 4  film at the time of thermal oxidation can be absorbed completely, thus making the occurence of bird peak minimum.
