Title: Magnetic head
Inventor: ONO TAKASHI
IPC: G11B5/29
Filed: 1987-04-08
Abstract: PURPOSE:To eliminate the need for an inter-channel shielding plate and shielding case which have been manufactured as separate parts and to simplify the assembling process of a magnetic head, by providing an inter-channel shielding plate between channels and magnetically closing the circumference of the head with side shielding plates. CONSTITUTION:A rear core 2 around which a magnetic coil 3 is wound and a front core 1 which is equipped with a surface to be brought into contact with and slid on a magnetic recording medium and forms a magnetic field together with the rear core 2 joined to the front core 1. Inter-channel shielding plates 9 which are formed as constituent parts of an one-body structure including the magnetic circuit with the coil 3 are provided against the entire area of the magnetic circuit and side shielding plates 11 which are formed as constituent parts of an one-body structure including the whole side faces of the magnetic circuit, shielding plates 9, etc., are also provided against the whole side faces. Since magnetically closed states are formed by the shielding plates 9 and 11 in this magnetic head, excellent preventing functions can be expected against the magnetism leakage from adjacent tracks. Therefore, use of any inter-channel shielding plate and shielding case which are manufactured as separate parts is not required, resulting in reduction in parts cost and working man- hours.

Title: Label printer
Inventor: TAKAI YOSHIHIRO
IPC: G01G23/00
Filed: 1982-05-21
Abstract: PURPOSE:To eliminate the possibility of any error of data in checking of a total and prevent any foul use of a label printer, by providing a unit-price change control key adapted to be able to change a unit price set on the balance side. CONSTITUTION:A label printer has a unit-price change control key 48 so that a unit price can be changed from the side of a balance 10 through the operation of the unit-price change control key 48. The contents of the data processing at this time are stored in another memory. Moreover, when a unit price is changed in a unit-price changeable state, a mark-down mode is set. On the other hand, when no unit-price change is effected, a rewrap mode is set. Thus, two modes are automatically changed over, and is addition, data on these modes are added to the respective memory devices. It is thereby possible to eliminate the possibility of any error of data in checking of a total or the like and prevent any foul use of the label printer.

Each scraper part 6 is supported by a scraper supporting part 8 provided with an avoidance mechanism 7 and freely advanced and retreated in the direction vertical to the surface 5, and each scraper part 6 is energized toward the surface 5 with a specified magnitude of pressure. When each scraper part 6 on the surface 5 strikes against a deposit 9 such as a weldment other than earth and sand and receives an abnormal force, the scraper part 6 is automatically separated from the surface 5 by the avoidance mechanism 7. The breakage of the scraper is prevented in this way.

Title: Circuit for detecting direction of ground fault
IPC: G01R31/08
Filed: 1992-03-11
Abstract: PURPOSE:To detect the direction of a ground fault at a high speed so as to make any expensive analog parts unnecessary by discriminating the direction of the ground fault by ORing a phase-delayed zero-phase current with a zero- phase voltage and measuring the pulse width which is the ORed output. CONSTITUTION:A phase delay circuit 1 obtains a waveform by delaying the phase of a zero-phase current. Then a logic circuit 2 obtains another waveform by ORing a zero-voltage with the waveform delayed 1 in phase. By measuring the pulse width of the waveform, whether a ground fault occurs on a power source side or load side is discriminated based on the value of the measured pulse width. Since the pulse width is measured, a counter 3 counts clock signals CLK only when the signal of the ORed waveform is high in potential. Then a comparator 4 compares the count value A of the counter 3 with a preset value B. When A>B, it is discriminated that the ground fault occurs on the power source side and, when A<=B, the fault occurs on the load side.

Title: Heat pump
Inventor: KOSASA TETSUO
IPC: F25B13/00
Filed: 1988-04-08
Abstract: PURPOSE:To secure the cooling operation from loss of pressure and make the operation free from disagreeable noise where there are a plurality of indoor heat exchangers by, in cooling, opening the valves and actuating the blowers only for the indoor heat exchangers to be operated and by, in heating, opening the valves for the indoor heat exchangers both to be operated and to remain at rest and actuating the blowers only for those to be operated. CONSTITUTION:In cooling, gaseous refrigerant having a high temperature and high pressure is conveyed from the high pressure side of a compressor 1, through a passageway 2a, 2b of a four-way valve 2, and to an outdoor heat exchanger 3, wherein the refrigerant is condensed into a liquid refrigerant and conveyed through valves 4A, 4B to pressure-reducing devices 5A, 5B and assumes the form of frost by reduction in pressure. This refrigerant in frost form extracts heat from the surroundings as it is vaporized in the indoor heat exchangers 6A, 6B so as to effect indoor cooling. The cooling is not affected, with the valves remaining closed and the blower at rest, in the rooms for which the individual operation switches are not turned on. In heating rooms, the valves are opened for the indoor heat exchangers both to be operated and to remain at rest and the blowers are actuated only for those to be operated. As a result, it is avoided for there to be a drop in heating capacity arising from shortage of circulating refrigerant that may occur from leakage of gaseous refrigerant through a valve into an indoor heat exchanger at rest where the refrigerant in condensed into a liquid and allowed to stand therein.

The precise mass number thus obtained is delivered to a ceintral processing unit 4 which delivers chemically possible composition formula as the output. The integer mass is obtained by rounding the precise mass number at one decimal. After discriminating the internal standard substance and the specimen from each other, bar graph output is delivered to a CRT 5 and a printer 6 so as to write mass number and the composition formula in the vicinity of the peak of bar graph.

Abstract: PURPOSE:To protect a heat exchanger from being damaged by jellyfish, by monitoring the behavior of the jellyfish beforehand by utilizing an ultrasonic wave and preliminarily lowering the electric output of a power station intentionally when a large school of the jellyfish gathers in the sea water intake port of the heat exchanger. CONSTITUTION:A signal is always emitted to the ocean from the ultrasonic sensor 3a arranged to an intake port 2 for taking seawater and, when the output thereof is applied to a large school of jellyfish, a reflected signal 4a is sent to an amplifier 12 and an operation part 14 to be operated and amplified to estimate the thickness of the school of the jellyfish 11, the distance between the jellyfish 11 and the intake port 2 and the moving speed of the jellyfish 11. The estimation in this case is performed by a judging part 15. As this estimation result, the signal from said judging part 15 is sent to the operation panel of a CPU 17 to allow the electric output of power station to automatically fall. By this method, installation machinery for treating seawater can be protected from damages due to the jellyfish.

IPC: G11C11/406
Filed: 1979-07-13
Abstract: PURPOSE:To make it possible for a unit to secure stable operation with the operation margin of an element widened by refreshing memory units, to be refreshed when one memory unit malfunctions, by changing memory units in number. CONSTITUTION:In normal operation, control circuit 5 refreshes dynamic semiconductor memory elements DM as many as possible at a time within its designed range. If malfunction detecting circuit 4 detects malfunction, malfunction-frequency counting circuit 9 counts up the capacity by one and circuit 5 decreases refresh units in accordance with the output of circuit 9 and also increases the refresh frequency equivalently. Therefore, since noises of the electric power source generated in refreshing operation are reduced, the operation margin of DM is expanded in comparison with that in malfunction occurrence and the stable operation of elements is secured.
