Title: Binder and magnetic recording material
Inventor: HAGIO SHIGERU
IPC: C09D175/04
Filed: 1988-08-17
Abstract: PURPOSE:To obtain a binder for a magnetic recording material excellent in dispersibility by constituting the binder of polyurethane resin produced from specific active hydrogen compounds and organic polyisocyanate. CONSTITUTION:The binder is composed of high molecular weight polyol having 200-2,000 equivalent, low molecular weight polyol, active hydrogen compound consisting of compounds containing active hydrogen with functional groups such as -COOX, -SO3X and -PO(OX)2 (wherein X represents NH4 or amine cation) and the organic polyisocyanate. This binder has excellent dispersibility to a magnetic powder, so that there is no need to use a dispersing agent which gives a bad influence on durability of the magnetic coating material. Thus, such a binder for magnetic recording material can be obtained that does not deteriorate the physical properties of magnetic coatings.

Filed: 1991-07-22
Abstract: PURPOSE:To improve flatness of a supporting electrode, and to obtain a switching element having excellent reliability by vapor-depositing carbon on a surface of the electrode to form an amorphous carbon film, and alleviating an uneven part present on the surface of the electrode. CONSTITUTION:An electrode layer 1 is formed on a glass board 1 by a vacuum vapor-depositing method. Then, carbon is further formed in an amorphous film by the same method, and a stripelike supporting electrode 4 is formed. When the surfaces of the electrode 4 before and after the amorphous carbon film is formed are compared to be observed, the fact that an uneven part present on a crystalline grain boundary of the electrode 4 is alleviated by the carbon film and flatness is improved is confirmed. Thus, the uneven part of the surface of the electrode can be flattened, and a switching element having high yield and high stability can be manufactured.

Title: Mutual interference compensation circuit for torque detection output and axial tension detection output
Inventor: TSUJI OSAMU
IPC: G01L5/12
Filed: 1984-09-29
Abstract: PURPOSE:To enable accurate control of a torque actuator and a shaft horsepower actuator, by compensating mutual interference between a torque detection output and an axial tension detection output in a circuit for extracting the outputs. CONSTITUTION:When an axial tension detection output of a torque axial tension cell 1 is extracted with a closed loop control circuit 9B, a signal is fetched from the axial tension detection output with an auxiliary circuit 15A. Moreover, a signal of the auxiliary circuit 15A is adjusted in the level with an adjustor 16A. Then, the signal of the same level as the torque detection output generated in the torque axial tension cell 1 when only the axial tension alone is loaded to a test piece 3, namely the torque detection output due to mutual interference is fetched. The signal is applied to a closed loop control circuit 9A opposite in the polarity to the torque detection output of the torque axial tension cell 1. Therefore, the torque detection output generated by mutual interference is canceled to compensate for the mutual interference. The torque detection output of the torque axial tension cell 1 is corrected likewise when extracted with the circuit 9A.

Title: Electric field sensor
Inventor: USUDA SHOJI
IPC: G01R15/24
Filed: 1985-09-17
Abstract: PURPOSE:To attain to extend the life of a sensor and to miniaturize said sensor, by changing the quantity of light passing through an optical fiber by utilizing the resonant vibration of a vibration plate comprising bimorph type piezoelectric ceramic to which voltage to be measured is applied to detect the same. CONSTITUTION:When voltage Vin to be measured is applied to a vibration plate 1, the vibration plate 1 comprising bimorph type piezoelectric ceramic is subjected to resonant vibration in synchronous relation to the voltage to be measured. This vibration plate 1 performs the resonant vibration of a deflection width synchronous to the voltage to be measured regardless of the magnitude of the voltage to be measured. As the result of the up-and-down deflection of a light screening plate 4 with the resonant vibration of the vibration plate 1, the light transmission paths of input and output optical fibers 6, 7 are intermittently blocked and, therefore, the light detector provided to one end of the fiber 7 outputs a signal. This detection signal has relation such that the magnitude of voltage to be measured is inversely proportional to the pulse width of the detection signal. Therefore, by knowing the quantity of emitted light from the output signal of the light detector, not only the presence of the voltage to be measured but also the voltage value thereof can be detected. By this constitution, a small-sized sensor having long life is obtained.
