Title: Damping device
Inventor: NAITO SHINJI
IPC: F16F15/03
Filed: 1987-06-12
Abstract: PURPOSE:To obtain free damping characteristic, by generating damping force brought on by Lorentz force, through a motion of a plate type conductor made of a paramagnetic material, fixed on a vehicle movable part, which angles with magnetic field generated by a magnetic field generating device of a vehicle main body. CONSTITUTION:When a fixed seat 1 on the vehicle main body side, and a fixed seat 2 on the wheel bearing side, are moved relatively with each other through a spring 3, a plate type conductor 6 made of a paramagnetic material, moves in the direction 7 which angles with the magnetic field, in a magnetic space of a magnetic core 5 formed by the magnetic field generating coil 4, and eddy current is generated inside the surface of the plate type conductor 6, by magnetic induction. Lorentz force brought on by the said eddy current and the magnetic field made by the magnetic field generating coil 4, acts on the plate type conductor 6, and this Lorentz force is used as a damping force. In this way, as a damping device without a mechanically movable part can be attained, the device becomes maintenance-free, and as the damping characteristic can be varied at high speed by a command of a control device, a nonlinear damping characteristic can be attained.

Filed: 1989-06-09
Abstract: PURPOSE:To stably perform magnetic field modulation overwrite by comprising a magnetic field modulation coil system of an inductor to generate high frequency magnetic field and a capacitor forming a resonance circuit, and using digital amplitude modulation. CONSTITUTION:A binary data system modulated with a modulator 1 is digital- amplitude modulated with an amplitude modulation circuit system 2, and is inputted to a magnetic field modulation coil system 3.

Title: Method and equipment for testing phase of power line
Inventor: OTA MICHIHIRO
IPC: H04B3/54
Filed: 1994-06-06
Abstract: PURPOSE:To easily test whether or not signals of power lines between two points for power line communication are in phase. CONSTITUTION:A transmission control means 3 of a transmission section 1 sends a transmission command for a half cycle at each cycle of a power frequency of a power line, transmission data stored in a storage means 4 are modulated by a transmission means 5 and sent to a power line via an isolation means 6. A reception section 2 receives a signal sent via the power line via the isolation means 7 and a reception means 8 demodulates the signal to extract data. The number of data received for a half cycle period the same as that of the sender side is accumulated by an accumulation means 9 and displayed on a display means 10. When signals on the power line between two points are in phase, the number of data for the half cycle period to be displayed is the same as the number of sent data and when the signals are not in phase and since the number is '0' when the power line is a single phase line, and is nearly 1/3 of that in phase when the power line is a three phase power line, in-phase or not in-phase is detected. Thus, it is not required to wire electric wires from two communication points and to compare voltage waves at the two points, then whether or not in-phase is set is easily detected.

Title: Semiconductor device
Inventor: HATASAKO KENICHI
IPC: H01L29/43
Filed: 1982-08-21
Abstract: PURPOSE:To obtain the semiconductor device, in which a resistance region consisting of a conductor can be formed in a small area, by connecting the resistance region to an electrode body through an insulating resistance film formed through a plasma chemical vapor growth method. CONSTITUTION:The insulating resistance films 6 are brought to a plasma state by applying a strong electric field of a gas of silane, ammonia, nitrogen, etc. at a temperature of 300-400 deg.C, and vapor-grown to a P type diffusion layer 2 as Si3N4. According to the constitution, since the silicon nitride films 6 are not changed into complete insulating films and are formed in structure in which currents leak partialy, dielectric breakdown is not generated so far as sufficiently large voltage is applied, and the films 6 display approximately ohmic property. Consequently, the area of the diffusion layer 2 can be reduced to a half or less because one part of resistance value can be obtained by the films 6.
