Title: X-ray apparatus
Inventor: TSUCHIYA AKIRA
IPC: H05G1/20
Filed: 1984-12-01
Abstract: PURPOSE:To provide a highly stable X-ray apparatus by preventing simultaneous turning on of both of the first and second thyristors. CONSTITUTION:The first shot of the driver pulse generated by the beginning signal of the X-ray radiation is amplified by a driver circuit 37 to be applied on a thyristor 12. Then the thyristor 12 is turned on to give current to a primary winding 6a during a half period, and subsequently, determined by a resonant circuit condenser 5 and the primary winding 6a an attenuating oscillation of the primary current occurs. This primary current is detected by a detecting means 16 and voltage-converted by an I/V conversion means 17. Afterwards the voltage converted primary current is detected as to its zero phase by a zero phase detecting circuit 30 consisting of a comparison circuit. The timing after this zero phase detection determines the operating frequency of the driver pulses, and the second and subsequent serial shots of the driver pulse depending on this frequency are applied to the thyristors 12, 14, which prevents the simultaneous conduction of the two thyristors.

Filed: 1988-10-11
Abstract: PURPOSE:To obtain a MOS transistor having LDD structure with a reduced number of processes by etching a silicon substrate after removal of a gate oxide film and implanting an N-type dopant obliquely into a step part of the substrate to provide a lowly doped N<-> type region. CONSTITUTION:After a resist film 6 is removed, an N-type dopant is implanted in an oblique direction as indicated by 10 and at an implantation angle theta as indicated by 11. For example, when a tangent of the implantation angle theta11 is 0.1, if the dopant is implanted into a flat part of a P-type silicon substrate 7 at a concentration of 10<x> a step part 12 of the silicon substrate will be doped at a concentration of 10<x-1> and therefore an N<-> type region having such a low concentration as represented by one digit can be provided there. After implantation of the N-type dopant, it is annealed. In this manner, the number of processes can be reduced and thereby time and cost required for manufacture of semiconductor devices can be also reduced. Further, variation in concentration ratio between the N<+> type regions and the N<-> type regions is minimized and the resulting products are allowed to have stable and uniform quality.

Title: Cathode-ray tube inspection device
Inventor: KURIBAYASHI YUKIO
IPC: H01J9/42
Filed: 1986-10-29
Abstract: PURPOSE:To automatically judge the quality of an outer conductive coating by making two or more probes composed of conductive substance contact with a graphite application part forming an outer conductive coating of a cathode-ray tube, and detecting resistance values between the probes, thereby making automatic judgement, on the mass production line, of the quality of the graphite application part. CONSTITUTION:With a pallet 7 momentarily stopped on a conveyor line 8, an air cylinder 5 is actuated to make probes 6 in contact with an outer conductive coating 4 of a cathode-ray tube on the pallet. At the same time, resistance value 11 (R1, R2, R3) between the probes is measured automatically to judge the quality in accordance with the resistance value. For example, if the outer conductive coating is uniform, respective resistance values become approximately equal; if, however, there is a defective part (where application is uneven) between B and C, the resistance values R1 and R3 of the outer conductive coating become less than 10K OMEGA with R2 becoming infinite. These resistance values indicate the existence of uneven application between B and C, enabling to judge the tube as defective and reject it from the conveyor line.

Filed: 1987-10-09
Abstract: PURPOSE:To reduce crosstalk noise during drive at night by reducing an intermediate frequency amplifier band width when it is discriminated that an automobile is driven at night. CONSTITUTION:A desired signal is selected and amplified by a high frequency amplifier circuit 2, an automatic gain control circuit 3, a mixing circuit 4 and a local oscillation circuit 5 from various signals inputted from an antenna 1 and converted into an intermediate frequency. The signal converted into the intermediate frequency is selected and separated for a desired signal only depending on the selection characteristic of an intermediate frequency amplifier circuit 6 and the result is amplified, and detected by a detection circuit 7 and the audible frequency component is amplified by a low frequency amplifier circuit 8 and the result is outputted from a speaker 9. In this case, whether or not an automobile is driven at night is discriminated by a night drive discrimination means 10 and in case of night drive, a band width variable adjusting means 12 makes the band width of the circuit 6 narrow to prevent crosstalk disturbance due to an undesired strong radio wave.

Title: Voltage generation circuit
Inventor: HARA MOTOKO
IPC: H02M3/07
Filed: 1993-10-13
Abstract: PURPOSE:To obtain a voltage generation circuit which consumes a less amount of power by providing such a clamp circuit that the electric resistance between the circuit and an earth voltage node becomes smaller when the voltage at a voltage output node becomes higher than the clamping level of the clamp circuit. CONSTITUTION:A clamp circuit 130 is constituted of p-channel MOS transistors l30a-l30f diode-connected in series between a voltage output node 100a and earth voltage node 100c and outputs the gate potential V5 of a p-channel MOS transistor 110g in a high-voltage detection circuit 110 from a node l30g to which the transistors 130b and 130c are connected. The gate potential V5 becomes VPP-¦V16¦-¦V17¦ when a high voltage VPP is lower than the clamping level VCL of the circuit 130, but is maintained at ¦V18>>+>>V19>>+>>V110>>+>>V111>> when the voltage VPP once reaches or exceeds the clamping level VCL. Therefore, the power consumption of this voltage generation circuit can be reduced, since a charge pump circuit does not make charge-pumping operations while the circuit 130 performs clamping operations.

Title: Voice reception display device
Inventor: TSUCHIYA HARUKI
IPC: G10L19/00
Filed: 1992-08-31
Abstract: PURPOSE:To allow a person to easily understand a reproduced content of a radio broadcast in a short time by recording the content while being compressed to an information quantity as less as possible. CONSTITUTION:When a reception means receives a broadcast and outputs a voice signal, a character code conversion means converts the voice signal into a character code and the converted character code is stored in a character code storage means. Since the voice signal is stored while being converted into the character code in this way, the information quantity to be stored is remarkably decreased. The character code string stored in the character code storage means is converted into a character by a display means as required and displayed as the character. The character display is convenient because the content is grasped by intuition in comparison with the voice sounding and the content is easily confirmed.
