Abstract: PURPOSE:To reduce the occurrence of electromagnetic wave noise and higher harmonic components by permitting a variable bias power to respond to a driving signal, to vary a bias current and to control the impedance of a secondary winding in accordance with a power factor. CONSTITUTION:A current transformer 16 which varies and adjusts an input voltage supplied to an inductive load 14 in accordance with the power factor of the load, a short circuit 18 connected to the current transformer 16, a variable bias power 20 inserted into the short circuit 18 and a control circuit 24 which responds to an output signal which is proportional to the power factor from a power factor detection circuit 22, controls the DC output current of the variable bias power 20 and varies the impedance of the current transformer 16 are provided. Thus, the input voltage is controlled by the variable bias power 20 connected to the secondary side terminal of the current transformer 16 and an AC voltage in a power line is prevented from being directly phase-controlled. Thus, the occurrence of magneto-electric noise is reduced and the higher harmonic components included in the load current is reduced.

Inventor: MARUYAMA YOJI
IPC: G11C11/14
Filed: 1986-03-05
Abstract: PURPOSE:To separate a pair of Bloch lines indirectly, and to make it unnecessary to separate them directly, by writing another pair of Bloch lines in the neighborhood of the pair of Bloch lines to be objected, and coupling and dissipating one side of another pair of Bloch lines with the one side of the pair of Bloch lines to be separated. CONSTITUTION:Before separating the pair of Bloch lines, a bias magnetic flux HB is impressed in an upward direction, and on the domain walls in a stripe magnetic domain 1, Bloch lines 2 and 3 form a pair. An impressing in-plane magnetic flux is impressed uniformly at the right side facing the HIP. Next, after permitting a prescribed current to flow in a writing conductor 6, and generating Bloch lines 4 and 5 additionally, the Bloch lines 3 and 4 are coupled, then being dissipated, and only the Bloch lines 2 and 5 remain in a separated state. Since the Bloch line 5 has quite the same structure as the Bloch line 3 stated previously, the above stated operation generates the same result as the one in which the pair Bloch lines 2 and 3 are separated. In a write time, the Bloch lines of plus and minus are always generated.

Filed: 1988-02-29
Abstract: PURPOSE:To perform the centering of a workpiece lens with high accuracy by intermittently carrying out the interposingly holding action of the lens by jigs while carrying out the jetting-out/stoppage of a pressure gas from air holes in the centers of cup shaped jigs which are mutually oppositely placed.

Abstract: PURPOSE:To prevent inferior contact with terminals in a motor sucker while eliminating the risk of short-circuit between terminals so as to enhance the safety by establishing electrical connection of the motor sucker with the use of sucking port terminals provided on a recessed surface in the outer periphery of an opening in a sucking port, and connection terminals on the motor sucker side. CONSTITUTION:Body terminals 30 are connected to a battery 4 through a terminal bed 8, and is removably connected to dust collecting box terminal 31 in a dust collecting box 2, and suction port terminals 32 are connected to the dust collecting box terminals 31 and are arranged on inclined surfaces 2a formed on the outer periphery of the opening of a suction port 13 in the dust collecting box 2 and extending rearward from both ends of the opening. The vacuum cleaner is used for cleaning a floor, a rush-mat or the like by removing the motor sucker 3. Since the positions of the suction port terminals 32 are on the inclined surfaces 2a extending rearward from both ends of the opening of the suction port 13, dust never enters into the suction port terminal 32. Further, when the cleaner is used with the motor sucker 3 being fitted, there is no possibility of inferior contact between the suction port terminals 32 and the connection terminal 33. A pair of suction terminals 32 are not made in proximity with each other, and accordingly, no short-circuit occurs between the terminals so as to obtain a high safety. Further, since both end parts of the opening of the suction port 13 are formed as the inclined surfaces 2a, it is possible to prevent dust from being blocked, and to suck dust laterally.

Abstract: PURPOSE:To adjust the quantity of circulating refrigerant in proportion to a change in an operating condition, by installing a bypass line having a bypass valve between the out let side of a compressor and the inlet side of a refrigerant heater and adjusting freely said bypass valve by a temperature sensor mounted to the outlet side of said refrigerant heater. CONSTITUTION:Between the outlet side of a compressor 1 and the inlet side of a refrigerant heater 6 installed is a bypass line which is provided with a first bypass valve 9, a first pressure control valve 13, a second bypass valve 10 and a second pressure control valve 14. During heating operation, a refrigerant enters an indoor heat exchanger 4 from the compressor 1 via a four-way valve 2 to warm a room. Then, the refrigerant enters a refrigerant heater 6 via a two-way valve 7 for collection service, a two-way valve 8 for release service, and a pressure reducing device 11, and returns to the compressor 1. The second bypass valve 10 is adapted to be open all the time and let refrigerant partially bypass the pipeline to the inlet side so that the circulating refrigerant may be heated. During heating operation, the first bypass valve 9 is kept open, but if the outlet temperature of the refrigerant heater 6 exceeds a specified value, a temperature sensor 12 will transmit a signal, thereby closing the first bypass valve 9 via a controller 16. As a result, a required quantity of circulation refrigerant can be maintained. During cooling operation, the first and second bypass valves 9 and 10 are kept open all the time.
