The opposing surfaces of the magnets are spaced a distance 2×lg from each other, and a vibrating membrane on which coils each having a conductive pattern are arranged is placed in a gap between any two adjacent rod-like permanent magnets in each of the two layers, where lg is a distance from the vibrating membrane to the surface of a magnet. The arrangement of the rod-like permanent magnets is optimized by using Wm, Tm, τp, and lg.

摘要： A power control unit for high-frequency dielectric heating is provided. The power control includes an input current detection section for detecting input current from an AC power supply to an inverter circuit and outputting input current waveform information. A conversion section converts the input current waveform information into a drive signal of the switching transistor of the inverter circuit so that instantaneous fluctuation of the input current waveform information is suppressed. An input voltage detection section detects input voltage from the AC power supply to the inverter circuit and outputs input voltage waveform information. A selection section selects the input current waveform information or the input voltage waveform information, whichever is larger. The conversion section also converts the selected input current waveform information or input voltage waveform information into the drive signal of the switching transistor of the inverter circuit.

摘要： An object of the present invention is to easily detect a short circuit failure in a current collector of a prismatic battery and prevent a short circuit caused by an existence of a burr generated while cutting or a spatter generated while welding the current collector to an electrode plate. A battery unit is housed in a metallic battery case. In the battery unit, current collectors having bent portions on both sides are fixed to face surfaces of an electrode plate group of a prismatic battery. The portions of the battery case, which correspond to the bent portions, are pressed in a thickness direction. Under the pressure, a short circuit inspection for a short circuit between the battery case and the current collectors of the battery unit is executed. When a projected object exists on the bent portion, a short circuit is generated between the battery case and the current collector by pressing so that a short circuit failure caused by a shape of the current collector can be detected.

摘要： A high-frequency dielectric heating device includes: a microwave output unit including an inverter unit using a semiconductor switching element, heat-radiating fins for radiating the heat generated by an IGBT, and a printed board having a thermistor for detecting the temperature of the semiconductor switching element, The thermistor is soldered to a leg portion of the semiconductor switching element or near to the leg portion thereof on the side of the soldering surface of the printed board. The device also includes: a booster transformer, a high-voltage rectifier unit, and a magnetron; and a heat-cooking chamber fed with microwaves radiated from the magnetron. When the thermistor has assumed a predetermined resistance, a power-down control operation is effected by greatly decreasing the power fed to the semiconductor switching element. Then, permitting the power fed to the semiconductor switching element to vary depending upon the resistance of the thermistor.
