IPC: G01L9/04
Filed: 1984-06-11
Abstract: PURPOSE:To elevate a reliability as well as to enable a correct pressure measurement by maintaining the thermal balance of the inside and outside of a semiconductor pressure transducer. CONSTITUTION:A semiconductor pressure transducer (TD) 1 is operated by a constant-voltage circuit 2 and a transistor (TR) 1 is functional as a constant-current regulated power source against resistance bridges R1-R4 together with bias resistances R5, R6 and at the same time the voltage between the base emitter of the TR1 shows a linear change for the temp., so the base point of the characteristic thereof is predetermined by a bias circuit 4 and the electrical signal equal to the inner temp. of the TD1 is accordingly generated for the output of an amplifier 3. On the other hand a thermistor RT arranged close to the outer part of the TD1 is induced to the surrounding temp. of the TD1 with bias resistances R7, R8, and the electrical signal equal to the surrounding temp. of the TD1 is generated for the output of an amplifier 6 by a bias circuit 7, amplifier 6. The output of the amplifiers 3, 6 is compared 8 and a heater 10 is driven in order that the thermal balance is kept by the inner part and outer part of the TD1. A correct pressure value signal S100 is thus obtd.

IPC: H02P27/08
Filed: 1997-05-12
Abstract: PROBLEM TO BE SOLVED: To reduce resonance due to modulation frequency components in PWM control and suppress electromagnetic noise and vibration. SOLUTION: A plurality of current commands Ir1-Ir8 are outputted from a motor control section 4 based on a current reference Iref and a rotor position detection signal Rp. Single-phase alternating currents I1-I8 are outputted by PWM control from inverters 3-1-3-8 according to the respective current commands, and supplied to an alternating-current motor 1 having a mutilayered winding comprising a plurality of single-phase windings. As a result, a rotating magnetic field with a plurality of poles formed is generated, and the alternating- current motor 1 is driven and rotated.

Inventor: KAJITA YUJI
IPC: H02M7/21
Filed: 1995-05-19
Abstract: PURPOSE: To obtain a rectifying circuit which reduces heat generation, simplifies a heat dissipating structure and has a high efficiency. CONSTITUTION: A rectifying circuit 33 which is connected across an AC power supply 31 and a load 32 is constituted of a P-channel MOSFET 34 the drain of which is connected to the AC power supply 31 and of a switching control circuit 35 which detects the potential difference between the drain and the source of the MOSFET 34 and which controls the MOSFET 34 so as to be turned on and off. The switching control circuit 35 comprises a comparator 36 which compares the drain voltage of the MOSFET 34 with its source voltage. When a current from a capacitance on the side of the load 32 starts to flow backward toward the drain from the source of the MOSFET 34 while the MOSFET 34 is turned on, the drain voltage becomes lower than the source voltage. As a result, the output of the comparator 36 which compares both voltages is inverted to a low level, a transistor 24 is turned off, the MOSFET 34 is turned off, and it is possible to prevent a phenomenon that an electric charge is passed to the side of the AC power supply 31 from the capacitance on the side of the load 32.
