Title: Electromagnetic cooker
Inventor: TANAKA TERUYA
IPC: H05B6/12
Filed: 1989-06-30
Abstract: PURPOSE:To convert the input power in a wide scope and to prevent the generation of noise by controlling the oscillation frequency to make the pulse difference between the signals relating to the output voltage of an inverter circuit and the current flowing through a resonant capacitor at a preset phase difference. CONSTITUTION:When transistors 11 and 13 are operated on and off alternatively depending on the signal from a driving circuit 31, a heating coil 19 and a capacitor 12 are set in a series resonant condition. As a result, the heating coil 19 generates a high-frequency power to heat a substance to be heated. By setting the oscillation frequency of an inverter circuit 9 at the resonant frequency of a series resonant circuit which consists of the coil 19 and the resonant capacitor 21, the series resonant circuit has only the resistance load making the load current at the maximum value. When the input power is controlled, the phase difference between the first signal and the second signal at 90 deg. or higher by a phase difference setting circuit 27, and thereby an induction load condition is generated making the inverter current IIN in a delayed phase to the power VIN. By setting in such a condition, the load impedance is increased and the current flowing to the circuit 9 is decreased, and thereby the input power can be controlled low continuously.

The q-axis current command Iq* is fed through a subtractor 12 to a vector-operating section 1. On the other hand, a d-axis current command Id* is produced, as a speed proportional part, by adding a d-axis current command Id0* to the d-axis current command Id1* and inputted to the vector- operating section 1. The speed control of a motor 4 is then performed by controlling an inverter power section 3. According to the arrangement, constant output control of a permanent magnet synchronous motor 4 can be realized, while enhancing the motor efficiency.

Abstract: PROBLEM TO BE SOLVED: To suppress the destruction of a battery at the time of collision of an automobile to the minimum extent by providing an assembled battery provided with an impact absorbing body in advance in a work region of inertia force which acts on the assembled battery when impact is generated. SOLUTION: As for the absorption of impact force applied on a storage vessel 2 in which an assembled battery is stored, impact force applied on the storage vessel 2 is absorbed by a spring 3, if the impact force is comparatively small. If large impact force is applied, an air bag 6 is operated to absorb the impact force. As for the absorption of impact force applied on the assembled battery, impact force applied on the assembled battery is absorbed by a capsule which is spread closely around the assembled battery to reduce the impact force applied on the assembled battery, if the impact force is comparatively small. When large impact force is applied, the capsule is compressed by the assembled battery 7 and the vessel 2. If compression force at the time exceeds the strength of the capsule, the capsule is broken to discharge reaction prevention agent which is filled inside it.

Abstract: PROBLEM TO BE SOLVED: To perform the encoding of a wide band with a high dynamic range by multiplying a prescribed transfer function to the difference between before and after the conversion process of both non-uniformly quantized and inversely quantized results and adding the result to an input signal. SOLUTION: The input signals X are supplied through an adder 110 to a non-uniform quantizer 120, the non-uniform quantizer 120 compresses the inputted signals of 24 bits to 16 bits and the compressed signals of 16 bits are outputted as output signals W, transmitted to the decoding device and inputted to an inverse quantizer 130.

A subtractor 140 outputs the different signal between the input signal of requantization and the output signal of the requantization, that is quantization noise Q. The quantization noise Q is fed back through a feedback circuit 150 having a transfer characteristic H1(z) to the adder 110.
