Title: Filamentary power supply of x-ray tube
Inventor: BABA SETSU
IPC: H05G1/34
Filed: 1988-10-31
Abstract: PURPOSE:To attempt miniaturizing the title power supply and improving reliability of control by detecting the primary-side power of a filamentary transformer, and forming a control system which controls the power at a given value. CONSTITUTION:An inverter 9 outputs a high-frequency pulsating voltage by the same action as that of a known PWM system inverter. The pulse width of the voltage depends on the difference between the output signal of an output setting unit 19 and the output signal of an analog arithmetic unit 17. Namely a control portion in the inverter 9 does the control action of squaring the output power of the inverter 9 with the set value of the output setting unit 19. The control system does its control action by regarding the primary-side power of the filamentary transformer 12 as power being consumed by a filament 7, and therefore it can set filament temperature to a given value. This makes it possible to miniaturize the power supply and also it is possible to improve reliability of control.

Patent JP-H05130734-A (JP)
Title: Power source protecting circuit for equipment using direct current power source
Inventor: NANBA MASAYUKI
IPC: H02J1/00
Filed: 1991-10-23
Abstract: PURPOSE:To implement the miniaturization and easier maintenance of the captioned protecting circuit adaptable to a small power equipment. CONSTITUTION:When a direct current power source is correctly connected to terminals 1 and 2 on the input side, the direct current flows to a relay 8 through a diode 9 if a switch 10 is closed. When the direct current flows, the relay 8 causes contacts 7a and 7b to be closed, thereby to supply the direct current to terminals 3 and 4 on the output side. On the other hand, when the direct current power source is reversely connected to the terminals 1 and 2 on the input side, the direct current does not flow even if the switch 10 is closed because its flow is blocked by the diode 9. The contacts 7a and 7b are not closed, either, thus allowing no direct current to be supplied to the terminals 3 and 4 on the output side. Therefore, it is possible to prevent the circuits on the equipment using the direct current power source from being destroyed by the application of any inverse voltage.

Filed: 1989-10-23
Abstract: PURPOSE:To perform sufficient ventilation at the stop time of a ventilating fan by supporting a pressure receiving plate at a partition plate for partitioning an air flow out passage and an air flow-in passage, and oscillating the pressure receiving plate downward and horizontally by a spring respectively at the air force-feeding and stop time of a fan, as well as interlocking the lid of an air exhaust port provided at a ceiling with the pressure receiving plate. CONSTITUTION:A pressure receiving plate 15 energized upward by a spring 16 is supported at a partition plate 9C for partitioning the air flow-in passage 12 and flow- out passage 11 of a ventilating fan 10 provided at a ceiling 8. At the time of operating the fan 10, the pressure receiving plate 15 is oscillated downward by pressure and energized in the horizontal state at the stop time of the fan 10. An air exhaust port 17 is provided at the ceiling 8, and an oscillatingly supported lid 18 is closably provided thereto. The lid 18 and the pressure receiving plate 15 are connected by a connecting rod 19. Air is thereby force-fed into a cage from the flow-out port 13 at the time of operating the fan 10. At the stop time of the fan 10, pressure to the pressure receiving part 15 is extinguished, so that the pressure receiving plate 15 is placed in the horizontal state, and in linkage with this, the lid 18 is released, thus performing sufficient natural ventilation.

Title: Liquid crystal display panel and production thereof
Inventor: MAEDA HIROSHI
IPC: G02F1/1362
Filed: 1991-10-23
Abstract: PURPOSE:To relieve a disconnection defect by connecting a disconnected signal wiring to a wiring for relieving by a wire bond via pads electrically insulated from proximity wirings on the liquid crystal display panel. CONSTITUTION:The pads 1, 2 at both ends of the signal wiring 5 where the disconnection defect arises and the pads 3, 4 at both ends of the wiring 7 for relieving are respectively connected by a wire bond 18 via the island-shaped intermediate pads 1c, 1d and 2c, 2d for relieving disposed between the signal wirings in order to relieve the above-mentioned signal wiring 5. The shapes of the island-shaped intermediate pads 1c, 1d and 2c, 2d for relieving are specific and are different from the shape of the pads at both ends of the signal wiring 5. Since the wiring is executed by the wire bond 18, a crossing part 20 between the signal wiring 5 and the wiring 7 for relieving is extremely decreased in the probability of the shorting between the wirings and the capacity of the relieved signal wiring. Such decrease leads to a decrease in the generation probability of defects, signal delay and signal noises. The island-shaped intermediate pads 1c, 1d, 2c, 2d for relieving are easily identifiable and the workability of the wire bond 18 is improved.
