Title: Roller surface reforming method
Inventor: TSUYUSAKI HIDEHARU
IPC: B65H5/06
Filed: 1988-01-19
Abstract: PURPOSE:To lower adhesive strength while coefficient of friction is kept by applying ultraviolet rays to the surface rubber of a pinch roller or the like used in acoustic and image apparatus to cause bridge reaction, whereby the skin layer of the rubber surface is hardened. CONSTITUTION:Ultraviolet rays are applied to the rubber surface of an abrasive finished roller 1 to form a thin hard layer on the surface. The rubber material of the roller 1 may be either natural rubber or synthetic rubber, preferably diene group rubber or natural rubber. Desirable wavelength, illumination intensity of irradiation time of applied ultraviolet rays are determined depending on the kind and use of the rubber material quality. Usually, a satisfactory treatment effect can be attained by irradiation of ultraviolet rays. An irradiation method of ultraviolet rays is required to uniformly irradiate the rubber surface of the roller 1 and carried out by using a suitable method, for example, by rotating the roller 1 with respect to an ultraviolet ray lamp 2 or applying ultraviolet rays from above and below while the roller 1 is caused by a conveyer.

Title: Storage battery device and power system
Inventor: KAWAKAMI SOICHIRO
IPC: H01M10/46
Filed: 1994-01-28
Abstract: PURPOSE:To stably supply power without decreasing the charge/discharge efficiency of a storage battery device with a plural of cells connected together in array by detecting abnormal cells and separating them therefrom and compensating lower voltage. CONSTITUTION:In a storage battery device, (m+1) sets of (n+1) secondary batteries 00-nm connected in series are connected in parallel to make higher voltage and higher capacity, and a series auxiliary power supply is provided therein. Switching elements are connected in series to unit cells so that, even when abnormal cells are electrically separated, the storage battery device can keep stable output voltage. For example, if, when one of secondary batteries is detected to deteriorate, the unit cell is separated therefrom and short-circuited at both the terminals, the output voltage in this line drops. In this case, because it is lower than voltage in other normal lines, the total current output of the storage battery device drops. So, a spare DC auxiliary battery is changeover connected to the battery in this line, where voltage drops, to compensate voltage and prevent the drop of current output.

Title: Electronic clock with power generation device
Inventor: YOSHINO MASASHI
IPC: H02K21/18
Filed: 1996-01-23
Abstract: PURPOSE: To obtain an electronic clock in which a power generation effect can be enhanced by a method wherein stator pole pieces are connected by a slender part, a leakage magnetic flux is utilized and a half-wave rectifier circuit is used. CONSTITUTION: The rotational motion of an unbalanced wheel whose center of rotation and center of gravity are eccentric is speeded up by a multiplying wheel train, and a rotor 20 is turned. A stator 21 is arranged so as to surround the rotor 20 which comprises a permanent magnet 20a, and a coil 22 is wound on a magnetic core 22a which is fixed to the stator. The coil 22 generates an AC electromotive force which is nearly sine wave-shaped. Because pole piece parts 21a, 21b of the stator 21 surround the rotor 20 together with a slender connection part 21c, a tensile torque which is going to stop the rotor 20 in a certain place is reduced, and the unbalanced wheel can be started easily even when the wheel is small. When the alternating current of the coil 22 is rectified and stored in an electricity storage means, a half-wave rectifier circuit is used as a rectifier circuit.  When the storage means is cut off, the coil 22 carries no current, the unbalanced wheel is speeded up so as to be set to conduction, energy is released, and its efficiency is not worsened. In addition, a rectification loss is reduced as the number of diodes is reduced.

Filed: 1991-01-29
Abstract: PURPOSE:To prevent the infiltration of moisture from a substrate surface and adhesive layer and to prevent the peeling and corrosion a recording layer by forming a groove region in the entire region wider than the recording region formed on the recording layer. CONSTITUTION:The grooves 6 for increasing the recording density in the radial direction of the recording surface is provided on the surface of a transfer layer 2 in the entire range wider than the recording region 8 formed on the recording layer 3, by which the groove region 7 is formed. Since the contact surface of the transfer layer 2 and the recording layer 3 is adhered at the rugged surfaces formed by the grooves 6, the infiltration of the moisture from the substrate surface and the adhesive layer 4 is prevented. Then, the peeling of the recording layer 3 and the corrosion of the recording layer 3 by the oxidation of the metallic material incorporated into the recording layer 3 are prevented. There is no possibility that the recording and reproducing functions of the recording region 8 are failed by corrosion.

IPC: G01R31/08
Filed: 1990-01-17
Abstract: PURPOSE:To enable the specifying of a section where a fault occurs even when an electric reception is made simultaneously from a plurality of lines by computing zero- phase components from data of currents and bus voltages in phases respectively to determine directions of faults in current detectors from a phase difference between both the results. CONSTITUTION:The newest data pertaining to a zero-phase voltage and a zero-phase current are stored into a memory 17 from a bus voltage transformer GPT and current detectors 9 and 10. An arithmetic section 18 reads a zero-phase current I01 from an addition circuit 14 from the memory 17 and when the current exceeds a fixed value, a phase difference is computed from a zero-phase voltage V0 read from the memory 17 as determined with an addition circuit 13. Direction of the current I01 is judged to be left when the current is the same in phase as the voltage V0 while to be right when it is opposite. Moreover, when each of breakers CB1 and CB2 makes, electric reception of one circuit is given from respective power source supply lines and when both the breakers make, electric reception of two circuits is given from both the lines. Hence, the type of condition is inputted. The arithmetic section 18 judges a fault section on specified conditions from above-mentioned information (presence and direction of zero-phase currents I01 and I02 determined from the detectors 9 and 10).

Filed: 1999-01-19
Abstract: PROBLEM TO BE SOLVED: To enable the design for decreasing the heat generated within a stacked diode module by arranging an inverse mesa type diode chip, via ac electrodes on a forward mesa type diode chip to integrally stack the chips. SOLUTION: An inverse mesa type diode chip can secure a withstand voltage, even through the thickness of an n-type layer is small. The thin n-type layer allows small resistance and small forward voltage to provide a low power consumption of the diode chip. Thus, an inverse mesa type three-diode chip 21 with a common anode 71 is arranged via ac electrodes 42, 43, and 44 on a forward mesa type three-diode chip 31 with a forward mesa type common cathode 51 to integrally stack the chips. Therefore, the inverse mesa type diode chip is arranged on the structurally beneficial upper side, because the thin n-type layer of the inverse mesa type diode chip can also secure a withstand voltage, and the forward mesa type diode chip with larger heat generated is arranged on the lower side which enables easy heat dissipation by means of thermal conduction.
