Title: Grounding trouble recognizing method
Inventor: NAKAMURA IKUO
IPC: H02H3/44
Filed: 1993-03-30
Abstract: PURPOSE:To make it possible to reliably recognize a grounding trouble and also to judge its direction by a particular method utilizing the dispersion of zero-phase voltage and zero-phase current obtained by digital processing. CONSTITUTION:Root mean square values are respectively calculated from one cycle waveforms of zero-phase voltage and zero-phase current and are stored as basic data. In the same manner, each root mean square value calculated from a subsequent waveform is compared to the basic data. If a changed portion of the root mean square values of voltage and current exceeds a predetermined value, it is compared to the root mean square value calculated from second and third cycle waveforms. If the changed portion of the basic data has exceeded the predetermined value continuously for three cycles, this is recognized as the grounding trouble. Also, if the changed portion of the basic data is less than the predetermined value, a root mean square value calculated from the waveform of a subsequent one-cycle is updates as the basic data. And also the comparison to the root mean square value calculated from the waveform of a subsequent one-cycle is repeated thereafter.

Title: Recording apparatus
Inventor: ARIMA HIROSHI
IPC: B41J31/16
Filed: 1986-04-24
Abstract: PURPOSE:To prevent sticking of film to a thermal head by constituting a film so as to form an endless track and feeding ink only to finely recessed faces. CONSTITUTION:Printing is performed by driving a thermal head 7 so as to produce the heat then producing bubbles in the ink held in recesses of a film 1 and ejecting the ink toward a facing paper 18 by the pressure of the bubbles. When a print head section 19 is driven in the direction parallel with the shafts of paper feed rolls 16, 17, an ink feed roll moves along a guide groove 12 because an ink feed tank 9 is held on a plinth 15 and contacts against the film 1. When film drive rolls 5, 6 are rotated under this condition, the film 1 travels and an ink feed roll 8 rotates frictionally. The ink in the ink feed tank 9 has been permeated through an ink feed shaft 10 to the ink feed roll 8 by the capillarity, whereby the recesses of the film 1 are filled with ink when the ink feed roll 8 is rotated. Consequently, the ink does not adhere to the thermal head.

Title: Fuel lid opener circuit
Inventor: NAGASE SHUJI
IPC: B60R16/02
Filed: 1985-05-07
Abstract: PURPOSE:To prevent a fuel lid from being opened careless while an engine is in operation by allowing a routing for opening the fuel lid to be interrupted while the engine is in operation. CONSTITUTION:When an engine is started by placing an ignition switch 11 on the starting position, as a generator 9 starts rotating linked with the rotation of the engine, electric voltage is produced at the terminal 'L' of the generator 9. This causes both ends of an excitation coil 13-2 to be equal in electric potential because of the actuation of a regulator allowing the excitation coil which has been energized, to be de-energized. In addition, as a normally closed contact 13-1 is returned to a closed position, electricity is turned on to a relay circuit allowing electric current to be sent to an excitation coil 7-2. Accordingly, this causes a normally closed contact 7-1 to be opened. This also causes a feed routing to a lid to be interrupted allowing an opener solenoid to be inoperative restraining a fuel lid from being opened.

Title: Information processor
Inventor: NII MASAAKI
IPC: G11B33/10
Filed: 1989-04-14
Abstract: PURPOSE:To always load a storing medium whose frequency in use is high and to reduce frequency in exchange by measuring time when the storing medium is loaded in a storing medium driving means after completing the write/ read-out of information. CONSTITUTION:A master control part 13 judges the input by a keyboard 12. At the time of requiring the reproduction of a disk C, whether the disk C is loaded in an auto-changer 7 is decided from the state of a priority holding memory 10. When the disk C is not loaded there, the disk which is being loaded now is restored to a housed position and the disk C is loaded to perform the reproduction. The loading time of the disk which is being loaded is reset at the time of completing recording/reproducing and at the time of exchanging. When the completion of recording/reproducing is decided by the master control part 13 and the data of a loading time measuring circuit 11 exceeds the maximum loading time of the disk C in the memory 10, the master control part compares the priorities of all the disks and selects the disk whose priority is maximum, then loads it to the changer 7 and the disk C is restored to the housed position. Thus, the frequency of exchange of the disks is reduced.

IPC: H01L27/118
Filed: 1983-05-31
Abstract: PURPOSE:To prevent the increase of chip area and thus contrive the yield improvement and cost reduction by connecting the I/O cell in an I/O cell region in the periphery of a basic cell region of matrix type arrangement to at least one basic cell. CONSTITUTION:The I/O cell 4 in a master process has a small area and small driving power. An input-output circuit having sufficient driving power is realized by connecting the basic cell 2 to such an I/O cell 4. For example, only a pair of complementary MOSFET's 6 and 7 are arranged to the I/O cell 4, and elements in core regions are used for inverters 8, an NOR gate 9, and an NAND gate 10. The gates 8-10 are used by making one or a plurality of basic cells adjacent to the I/O cell 4 as exclusive to the input-output circuit, or combining adjacent unnecessary elements with the I/O cell in the core region. This manner enables to form many inputs and outputs without enlarging the I/O cell region 5, allowing to have sufficient driving power, and thus to contrive the effective utilization of cells.
