Title: Acceleration detector
Inventor: YASUKAWA TAKESHI
IPC: G01P15/02
Filed: 1986-12-10
Abstract: PURPOSE:To simplify the structure of an acceleration detector and to reduce the size and weight by composing the detector of a magnetic spherical body floating in a ferromagnetic body charged in an enclosed container made of a nonmagnetic body, and an exciting coil, a detection coil, and a holding coil arranged outside the enclosed container on its center line. CONSTITUTION:Coil assemblies 4a and 4b are arranged outside the enclosed container 1 of the acceleration detector on its center axis X-X line. Those coil assemblies consists of a sensing coil, an exciting coil, and a detection coil. When G operates to right in parallel to the center axis X-X line, the magnetic spherical body 3 is displaced in the opposite direction from the direction of G. Consequently, the ferromagnetic fluid decreases in concentration on the left side in a figure, so the magnetic resistance of a magnetic circuit produced by a left detection coil decreases to generate a differential output voltage between two detection coils, so that the differential output is proportional to the displacement quantity of the ferromagnetic fluid 2 accompanying the displacement quantity of the ferromagnetic spherical body 3. Thus, the value of G can be detected from the differential output voltage, so the structure is simplified.

Title: Power unit
Inventor: SAKO HIROYUKI
IPC: H02M7/06
Filed: 1993-11-25
Abstract: PURPOSE:To provide a power unit where the improvement of power factor and the improvement of higher harmonic wave distortion can be materialized and the circuit constitution is simple without a pause division of an input current. CONSTITUTION:A resonance circuit 2 composed of an inductor L1 and a capacitor C1 is connected to an AC power source 1. A feedback winding n, which feeds back the high frequency AC voltage of an inverter circuit 3, is connected in series to the capacitor C1. The full waves of power voltage, where the resonance voltage of the resonance circuit 2 is superposed, is rectified with a diode bridge DB, and it charges a smoothing capacitor C1. An inverter circuit 3 converts the DC power being supplied after being smoothed in a smoothing capacitor C0 into high frequency power, and this lights a discharge lamp 4 through a transformer T for output. The power voltage where resonance voltage is superposed is higher than the voltage across the smoothing capacitor C0, over the whole area of its one cycle. Accordingly, an input current can be passed to the roughly whole area of one cycle of the AC voltage of an AC power source 1.

Title: Manufacture of anisotropic rare earth permanent magnet
Inventor: TAWARA KAZUNORI
IPC: H01F41/02
Filed: 1988-11-22
Abstract: PURPOSE:To manufacture the title permanent magnet easily without deteriorating magnetic characteristics and without generating a crack at all by executing sintering and aging treatment, quenching a sintered body while extracting the sintered body from the inside of a refrigerant before the temperature of the sintered body reaches the temperature of the refrigerant and elevating the surface temperature of the sintered body. CONSTITUTION:An RCO5 group material is used as a powder permanent magnet material. When silicone oil at a temperature of 175 deg.C is employed as a refrigerant and a sintered body is extracted at 830 deg.C from a heat treatment furnace and dipped into silicone oil at 774 deg.C after three sec, the temperature of the sintered body is lowered up to 535 deg.C at a stroke after 0.6sec, and the temperature is lowered gradually. When the sintered body is extracted from the inside of silicone oil at the time of sixteen sec and 202 deg.C after the start of quenching, a surface temperature is elevated gradually, reaches to 470 deg.C for twenty-four sec after extraction, and reaches to 95 deg.C by air cooling. The surface temperature of the sintered body is increased owing to the transfer of heat toward a surface from the central section of the sintered body, thus reducing the temperature difference of the central section and surface of the sintered body, then completely removing the generation of a crack.

Filed: 1993-11-02
Abstract: PURPOSE:To adjust brightness of data display arbitrarily by changing luminance of a display section in accordance with corresponding luminance information when a signal which specifies luminance is inputted from a remote controller. CONSTITUTION:A control section 1 stores display data which is sent from a telephone line, converts the data to output a display signal for a display section 2, and transmits luminance information which adjusts brightness to a luminance control circuit 3 when it receives transmission request of data which adjusts brightness from a remote controller 4. When luminance information transmission request is outputted to the control section l from the remote controller 4, the control section 1 judges whether it is luminance information or display data. In the case of luminance information, it sends a signal based on the luminance information to the luminance control circuit 3, and the luminance control circuit 3 changes luminance of a display element of the display section 2 based on the signal. Consequently, a user can adjust display to the brightness which corresponds to the environment of installation place of a data display device.
