Title: Transmission line switching system
Inventor: YAMASHITA HIROSHI
IPC: H04L1/22
Filed: 1989-02-27
Abstract: PURPOSE:To prevent an interruption signal by providing an abnormality detection means and a means switching a transmission line from an current system into a standby system, retarding a received signal by a delay time set for an abnormality detection time or more and outputting the result to a switching means. CONSTITUTION:When a signal A transmitting on an active system transmission line 2a is interrupted, an abnormality detection circuit 3c detects it to send a switching signal C to a selector circuit 3d after the abnormality detection time T lapses. On the other hand, a signal E outputted from an active system delay buffer 3e and a signal F outputted from a standby system delay buffer 3f are retarded by the delay time Td more than the abnormality detection time T. Thus, the signals E, F still have the preceding frame when the signal C is outputted. The circuit 3d switches the output signal G from the signal E to the signal F according to the signal C. Thus, the output signal G is outputted without being interrupted in the middle of a frame string.

Abstract: PURPOSE:To enable the capacity of a rotary anode X-ray tube to be increased, enhance the cooling efficiency, and enable constantly stable X-ray photographing to be carried out by installing a spraying cooling equipment, with which the highly heated part of a vacuum case is cooled by cooled oil sprayed from it, within a housing. CONSTITUTION:X rays are produced when high voltage is applied across a cathodic body 2 and an anodic target 5 and electron beams are discharged from the cathodic body 2 onto the anodic target 5. An insulating oil 14 fed from an oil cooling equipment 15 is sent through a tube 17 into an oil case 12, and is sprayed on a curved part 1c of a vacuum case 1 from spray holes 12b. Then, the oil 14 sprayed on the curved part 1c passes through a space 18 formed between the vacuum case 1 and a frame 10. As a result, since the cooled insulating oil 14 is directly sprayed from the spray holes 12b of the oil case 12 onto the surface of the curved part 1c heated to high temperature, extremely effective cooling can be expected.

Title: Gate control circuit for gate turn-off thyristor
Inventor: SATOU MASAYOSHI
IPC: H02M1/06
Filed: 1981-03-31
Abstract: PURPOSE:To reduce the power consumption of a gate control circuit by detecting the turn OFF of a GTO at the gate control circuit side and stopping the supply of OFF gate current. CONSTITUTION:When a GTO1 is turned OFF and a reverse voltage is applied between the gate and the cathode of the GTO1, the rise rate of the OFF gate current becomes small, and the rise rate of the primary current of a pulse transformer 6 becomes small. Accordingly, the voltage of a reactor 12 becomes small, and the cathode voltage of a diode 14 becomes small. Since a zener diode 16 is set at its zener voltage to detect the voltage variation, a transistor 20 becoms ON. Since a flip-flop 21 operates by a signal varying from ''1'' to ''0'', the output of the flip-flop becomes ''0''. Since the cathode voltage of the diode 22 becomes  zero, a base current does not flow through a transistor 7, and the transistor 7 is  interrupted to stop the OFF gate current of the GTO1.

Filed: 1989-03-01
Abstract: PURPOSE:To prevent the malfunction through a pulse-like noise in an input by inhibiting counting of an updown counter, when an input from a comparator does not become the same value for a specified period of time and over. CONSTITUTION:While the output polarity of a comparator 3 is positive, an updown counter C1 continues to count up and the ON periods of PWM signal and FETTr1 lengthen so that the mean value of the current thereof grows larger and the output voltage of a switching regulator (SWR) rises. When the output voltage of SWR exceeds a reference value, the output polarity of said comparator 3 is reversed, the updown counter C1 is switched to a down-counter, its attribute is counted down, and the output voltage of SWR falls. In this manner, the output voltage of SWR, i.e., the voltage of output 1 and output 3 is controlled to a certain value. The voltage of output 2 is controlled with higher accuracy by a regulator 4.

Abstract: PURPOSE:To reduce the load applied to a solenoid during the operation by rotating a cam-driven plate to the position to close a control switch, sucking a rotary lever with the solenoid to hook it on the cam-driven plate, and holding the control switch at the closed state with the cam-driven plate. CONSTITUTION:When the timer time is set with either an operating shaft 23 or an operating lever 52, a cam-driven plate 43 is rotated interlockingly with the operating shaft 12 or the operating lever 52 to close a control switch 40.

The rotation of the cam-driven plate 43 is completed before the excitation of the solenoid 21, and the solenoid 21 needs to suck the rotary lever 25 only. The load applied to the solenoid 21 is thereby reduced during the timer operation, and a large suction driving force is not required accordingly.
