Title: Gas leakage alarm device
Inventor: UNO TAKASHI
IPC: G01N27/12
Filed: 1990-01-24
Abstract: PURPOSE:To avoid an alarm owing to the detection of miscellaneous gas at the time of no flow of town gas and LP gas by providing a control signal input part which inputs external information and controls an oscillation circuit or an annunciator. CONSTITUTION:Even if gas leakage is detected by a sensor 1, and the output of a detection circuit 2 appears, as long as an external signal is not impressed to an input terminal 8, and the output of a control signal input part 9 does not appear, an AND gate 10 does not open. Namely, only when a gas flow rate signal from a gas meter, for instance, is inputted as the external signal, the AND gate 10 opens, and the oscillation circuit 3 operates so as to make the annunciator 5 sound or a light emission element emit light, and simultaneous ly, an alarm signal is outputted from a signal output part 6 and appears at an output terminal 7. Thus, even if the sensor 1 senses the miscellaneous gas such as spray gas, etc., excepting when the gas flows in the gas meter, the sounding of the annunciator 5 or the emission of the light of the light emission element can be avoided.

Title: Induction heating device
Inventor: NAKAGAWA TATSUYA
IPC: H05B6/12
Filed: 1993-01-29
Abstract: PURPOSE:To eliminate a voltage dividing circuit of high withstand voltage and high accuracy from a synchronous detecting circuit, and lower cost by constituting the synchronous detecting circuit in such a way as capable of generating a synchronous signal based upon voltage generated in a search coil wound around a magnetic core forming a part of a magnetic circuit laid in the vicinity of a heating coil. CONSTITUTION:When a switching element 6 is actuated with a pulse signal from a PWM modulator 12 via a driver 13 and an inverter 5 is thereby caused to start operation, rectified and smoothing current supplied to the inverter 5 is cyclically switched on and off, and converted into a high frequency of several tens of hundreds Hz. This high frequency is applied to a heating coil 4 for the induction heating of a pan. In this case, voltage waveforms of several volts easy to be processed with a comparator 16 are generated by the search coil 14, depending upon a switching waveform applied to the coil 4. The generated voltage waveforms are compared in the comparator 16. Then, the rising edge of the waveform is detected with a differentiating circuit 22 on the basis of output from the comparator 16, thereby generating a synchronous signal. This synchronous signal is used to keep synchronous state with the pulse signal from the modulator 12 for driving the element 6. Thus, a switching loss is restrained to low level, and good switching operation is performed.

IPC: H04B17/18
Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To exactly detect antenna damage by comparing the respective outputs of adding means and discriminating the possibility of antenna damage based on the result when the output of a counting means becomes a prescribed value. SOLUTION: A speech control circuit 10 operates an audio circuit 9 and a transmission circuit 11 through a speech control signal and simultaneously operates a damage detector 6 for antenna. At the device 6, there are a counter 6-1 for measuring speech time and a counter 6-2 for counting the number of times of speech. During speech, quantized reception level signals outputted from A/D converters 4a and 4b for fixed speech time are sampled while using the counter 6-1, added by adders 6-3 and 6-4 and stored in storage devices 6-5 and 6-6. When speech is finished, the average of reception levels at respective antennas is calculated by the devices 6-5 and 6-6 and the counter 6-1, stored in devices 6-9 and 6-10 and added to the value up to the last time.  When this added value becomes the number of times of speech determined at the counter 6-2, the antenna having less difference is discriminated as antenna damage.

Title: Recorder and reproducer
Inventor: NAKANO KENJI
IPC: G11B20/10
Filed: 1982-02-01
Abstract: PURPOSE:To attain correct reproduction at all times even if tape jitter takes place, by making the windth of window detecting sound signals at reproduction broader than the sum of the recording part of the sound signal at recording and the tape jitter fluctuating. CONSTITUTION:To prevent adverse effect of noise, in conventional systems, a window signal equal to that at recording is applied to a PCM demodulation/ time axis expansion circuit 19 and the circuit 19 is driven only during this signal. In this invention, to the window signal at recording, a window signal at reproduction as expressed in figure A is widened by alpha each to front and rear part as expressed in figure B. The value of alpha is larger than the maximum value of the jitter portion beta. Thus, in this device, even if jitter exists in a reproduced PCM signal as expressed in figure C, the circuit 19 is driven during the period of the PCM signal and correct reproduction is performed. Even if there is more or less noise at the front and rear part of the PCM signal, it is no problem because the demodulation is performed after the synchronizing signal at the beginning of the PCM signal at the circuit 19.
