Title: Optical recording medium
Inventor: KAWAKAMI HARUO
IPC: G11B7/243
Filed: 1987-07-28
Abstract: PURPOSE:To shorten the time for recording and erasing of information, to stabilize the long-term preservation of recorded information and to increase the number of repetitions of recording and erasing by specifying the compsn. of the optical recording medium of a rewritable type optical disk for which the reversible phase transformation of an optical recording material generated by projection of laser light is utilized. CONSTITUTION:This recording medium is constituted by forming a SiO2 film on the surface of a substrate consisting of polycarbonate, etc., provided with tracking grooves, providing the recording material, i.e., medium film, thereon and further, depositing a surface protective film consisting of org. matter for the SiO2 film successively thereon. The alloy expressed by the general formula INxTe100-x is used for the medium compsn. and is specified to a 35<x<45 range. This medium, therefore, has a high m.p. and high crystallization temp., has a stable amorphous state and effectively absorbs semiconductor laser light. The generation of phase sepn. and phase segregation by heating and cooling is obviated. The time for the recording and erasing of information is thereby shortened and the long-term preservation of the recorded information is stabilized; in addition, the number of repetitions of recording and erasing is increased.

IPC: H02M7/48
Filed: 1986-08-13
Abstract: PURPOSE:To prevent a main circuit switching element from breakdown due to overvoltage application by giving an ON signal forcibly to a switcing element when all switching signals on a positive or negative pole side are OFF signals. CONSTITUTION:A current-type power converter is composed or transistors 31-36 forming a converter, a DC reactor 4, transistors 51-56 forming an inverter and others and its controlling apparatus is composed of a direct current detector 8 and one-chip microcomputers 10, 11 supplying pulse patterns to transistors 31-36 and 51-56 to drive them. In this case, the converter and inverter are provided with a forced ON signal generator 23. Said generator 23 operates to give an ON signal forcibly to tran-sistors when all switching signals on positive and negative pole sides are OFF signals while the power converter is operated. Thus, no high voltage is generated in the reactor 4 and transistors can be protected from being affected adversely.

Abstract: PURPOSE:To properly forming both a filling-up part and a carrying layer and to improve quality of a monolithic catalyst and to enable cost reduction by simultaneously forming both the filling-up part and the carrying body on the monolithic carrier for purifying exhaust gas. CONSTITUTION:The lower end surface W11 of a monolithic carrier W is allowed to abut against the upper end of the inner wall part 12a of a lower member 1 and an upper member 2 is allowed to abut against the upper end surface W21 and held by opposing the lower aperture 2a to a central space 3. Then slurry S2 for filling-up is fed and circulated to the ring-like space 4 of the member 1 with a pump 54. At this time, the liquid level of slurry S2 is held constant at the position higher than the upper end of the inner wall part 12a and therefore a filling-up part W5 is formed until the same position as the liquid level of slurry S2 in the lower outer peripheral part W12. Then slurry S1 for a carrying layer is fed to the upper inside W23 through the introduction port 2b of a slurry introducing pipe and stuck on the inner wall surface W4 by gravity and also allowed to flow down to the central space 3. Thereafter compressed air is fed from the lower aperture 2a to blow off excess slurry S1 remaining in the communication holes W3.

Title: Non-saturated type mos transistor
Inventor: SAITOU KAZUYUKI
IPC: H01L29/78
Filed: 1983-10-08
Abstract: PURPOSE:To obtain the titled transistor by a method wherein a source, drain, and substrate are put in the same conductivity type, and the transit of majority carriers is controlled by change of the state of electrons in the neighborhood of the interface between a gate insulation film and the substrate from inversion or depletion to accumulation. CONSTITUTION:The P<+> source 2 and the P<+> drain 3 are provided in the P type substrate 1, and the gate electrode 4 is attached via insulation film 5. Further, the substrate is doped with a killer such as Au, or the back of the substrate is provided with an N-layer or an insulation layer 12, or the outside of the element region is provided with an N- layer or an insulation layer 13; thus, the characteristic is contrived to improve by isolation. In this construction, instead of reverse bias between the source and drain, Vs=0 is applied to the source, and required VD and VG are applied to the drain and gate, respectively. At this time, carriers do not accumulate in the substrate because of no generation of barriers among the substrate, source, and drain; and accordingly space charges do not generate under the source and drain. Then, fine formation can be carried out independently of the effect of short channel, and then this transistor of high input impedance having a small parasitic capacitance with the substrate and capable of high speed action can be obtained.

Title: Magnetic-field test equipment for thin steel belt
Inventor: ANDO SEIGO
IPC: G01N27/83
Filed: 1990-07-19
Abstract: PURPOSE:To easily elevate detecting sensitivity of a magnetic sensor by positioning the magnetic sensor in the running direction on the position moved a very small distance from the center position between magnetic poles on the running side which is decided from residual magnetization characteristic of a thin steel belt. CONSTITUTION:A magnetic sensor 11 is fitted on the position moved by a very small distance DELTAX0 on the running direction side of a thin steel belt 10 from the center position P between magnetic poles 4a, 4b. A decided movement quantity is generated between a vertical magnetic field characteristic E when the fault-free thin steel belt 10 is arranged opposite to the magnetic poles 4a, 4b, and a vertical magnetic field characteristic G when the belt 10 is run in the arrow mark A direction, this is decided from the residual magnetization characteristic of the thin steel belt 10, and as the sensor 11 is fitted on the position where the characteristic G becomes to be zero level, namely, at the distance DELTAX0, floating magnetic flux is not generated on this position. Hereby, even though sensitivity of the sensor 11 is elevated, it is not saturated, and leaked magnetic flux can be accurately detected even at small scaled fault.

Filed: 1989-07-21
Abstract: PURPOSE:To make it possible to measure the weight, the position of the center of gravity and the moment of inertia of an arbitrary three-dimensional body by attaching a material to be measured to an attaching jig one time. CONSTITUTION:Under the state wherein a material to be measured 30 is attached, the output signal of each sensor 20 is amplified in an amplifier 40. Static load data are obtained with a converter 42 based on said amplified output. Said static load data are sent into operators 43 and 44. The operator 43 operates the weight and the position of the center of gravity of the material to be measured 30. Then, a base stage surface 22 is vibrated with an actuator 27 so as to obtain the resonance frequencies of the material to be measured 30 and a measuring system. Thus, the dynamic response data are measured. The resonance frequencies are obtained with the operator 44 based on said data. When the resonance frequency around an X axis is obtained, the material to be measured 30 and the surfaces 21 and 22 are vibrated at the same phase as the sensor 20, and control is performed with a control signal generator 46 so as to excite the vibration in rotation around the X axis. The response is obtained with the converter 42, and the resonance frequency is operated 44. The resonance frequencies around a Y axis and a Z axis are obtained by the same way. In this way, the weight, the position of the center of gravity and the moment of inertia of the material to be measured can be obtained.
