Abstract: PURPOSE:To detect the current of a Geiger Muller counter (GM counter) by a simple structure, by providing a transformer used in both of an oscillation coil and a boosting transformer as a high voltage generation circuit for applying high voltage to the GM counter to convert the frequency thereof to a voltage value. CONSTITUTION:As a high voltage generation circuit for applying high voltage to a GM counter (a), a transformer T1 used in both an oscillation coil and a boosting transformer is provided and high DC voltage (high voltagle) is obtained from the high voltage current generated in a secondary side through diodes D1, D2 and condensers C2, C3. This high voltage is applied to the GM counter (a) through a resistor R2 and a current is flowed into the GM counter (a) from the high voltage terminal thereof. Therefore, the current increases as the dose ratio of radioactive rays allowed to irradiate the GM counter (a) becomes high FFTQ2 guides oscillation frequency for transmitting the current of the GM counter (a) to both terminals of a resistor R4 and this oscillation frequency is converted to voltage VC through a resistor R5 and a condenser C5. By this method, voltage showing the relative value of the current of the GM counter (a) and voltage of a reference voltage oscillation (b) are compared by a comparator (c) to make it possible to detect the current of the GM counter.

Title: Binary circuit
Inventor: MORITA HIDEKI
IPC: H03K5/08
Filed: 1981-02-21
Abstract: PURPOSE:To achieve accurate binarization with high resolution, by picking up only harmonics of an analog signal and obtaining a threshold value through the use of it, in a circuit binarizing an analog picture signal. CONSTITUTION:When an analog signal P1 inputs to a high pass filter 1, a signal P2 rejecting the low frequency component of the signal P1 is outputted. This signal P2 is multiplied by -1 with a  magnifier 2, and an output signal P3 is applied to an adder 3. Since the analog signal P1 is applied to another input of the adder 3, a signal P4 adding the signals P1 and P3 is outputted. Since the signals P1 and P3 are added with inverted phase, the uneven waveform is cancelled with each other to be envelope waveform. When a comparator 4 compares the signals P4 and P1, the signal P4 is reduced to a threshold value and a sharp copy P5 with high resolution is obtained.

Abstract: PURPOSE:To enable an ultrasonic humidifier, whose run-away is not occured at the time of burning without liquid to realize by a method wherein titanate, zirconate and niobate constituted of specific blending ratio are designated as basic constitution. CONSTITUTION:In the ceramic piezoelectric material with titanate, zirconate and niobate as basic ingredient, composition of the ceramic piezoelectric material is constituted of 45-50mol% titanate, 41-46mol% zirconate and 5-10mol% niobate and 1-2wt% cobalt oxide, 0.1-0.4wt% manganese oxide and 0.1-0.3wt% magnesium oxide as sub composition being added thereto at the same time. If an electrostrictive strain vibrator using ceramic piezoelectric material is in a state of burning without liquid, electric current volume is reduced sharply in comparision with normal time, and becomes closely to a level in the state that electric scource of the ultrasonic humidifier is cut off, then the electrostrictive strain vibrator is protected from breakdown. Thereby, preventive circuit for liquidless burning can be eliminated, thereby markedly, cost-down of the ultrasonic humidifier can be realized.

Title: Electronic circuit
Inventor: TSUBOI TOSHIHIDE
IPC: H03K5/08
Filed: 1988-02-04
Abstract: PURPOSE:To reduce an area shared by an electronic circuit detecting it whether or not the power voltage having been dropped in the past by using a depletion MOSFET so as to utilize its characteristic. CONSTITUTION:With a power voltage decreased, since source-gate voltage of both an N-channel depletion MOSFET 13 and a P-channel depletion MOSFET 11 are decreased, they are turned on. Then the drain and source of the FET 13 and the drain and gate of the FET 11 go nearly to a GND level and the state that both the FETs 11, 13 are turned ON is made stable. Thus, even when the power voltage is once decreased and restored, the drain potential of the FET 13, that is, the potential of an output signal line 15 remains nearly at the GND level. Whether or not the power voltage has been dropped before is recognized by observing the potential of the signal line 15 in this way. Moreover, the increased area shared by the circuit on an LSI chip is avoided.

Abstract: PURPOSE:To enable easy and effective correction of cross misconvergence by dividing vertical auxiliary coils, which are connected in series with vertical deflection coils, into two parts so as to form first and second coil parts and connecting one coil part in parallel with a pair of diodes whose polarities are reversed to each other. CONSTITUTION:Vertical auxiliary coils 20 connected in series with vertical deflection coils 7 are divided into two parts so as to form first and second coil parts 20a and 20b. A pair of diodes 21 and 22 whose polarities are reversed to each other are connected in parallel with one part out of the first and second coil parts 20a and 20b, for example, the coil part 20a. Therefore, currents flowing across respective coil parts of the vertical auxiliary coils 20 can be controlled by the diodes 21 and 22, so that intensity of a magnetic flux, which is generated by the vertical auxiliary coils 20 and varied at a period of vertical deflection, is controllable. Hence, cross misconvergence on a screen can be corrected by controlling a vertical deflection magnetic flux supplied to horizontal auxiliary coils 3 and 4 so as to change respective circuit inductances of a pair of horizontal deflection coils 1 and 2.
