Title: Overcurrent protection circuit of photoelectric switch
Inventor: HIROSE TAKUMI
IPC: H03K17/78
Filed: 1986-03-04
Abstract: PURPOSE:To eliminate the need for an externally mounted capacitor and an exclusive counter for overcurrent reset by adopting the constitution that a counter for a photodetection signal acts like a counter for overcurrent reset. CONSTITUTION:When an overcurrent flows to a relay, a transistor (TR) 12 is turned on and an inverter circuit 14 outputs a high level overcurrent detection signal S14. When a clock pulse P6b is given to a trigger terminal T of a flip-flop circuit 7, a high level is read and inverted to the set state (operating state) and an output signal at an output terminal Q is outputted as a reset release signal S7. Then an output signal S8 is bypassed and made ineffective, an output TR 9 is turned off to interrupt the power application to a relay. Then the counter control circuit 3 changes the output signal S3 into a high level synchronously with the leading of a reset release signal S7 and the counter 2 counts a count pulse P6a. When the count reaches the setting value, a reset pulse P2 is given to the flip-flop circuit 7, which is inverted immediately into the reset state (restoration state) to stop the output of the reset release signal S7.

Title: Band pass filter
Inventor: KOYAMA MIKIO
IPC: H03H11/04
Filed: 1987-03-04
Abstract: PURPOSE:To design the titled filter without adopting any approximation by connecting each one input terminal of two integration circuits to the other output terminal so as to constitute a loop circuit (biquad circuit) and using at least two sets of loop circuits. CONSTITUTION:Each component of inductors and capacitors of the circuit corresponds to an integration circuit and the integration circuits are coupled by a capacitor (Ck) to give/receive a signal of each loop circuit. In the integration circuit, capacitors required for the integration are all incorporated and a voltage at a control terminal (Vcontrol) is controlled to control the filter characteristic against the component variance. Moreover, the operational amplifier type is not employed for the integration circuit, but differential amplifiers having an excellent frequency characteristic is used to attain the high frequency operation. In integrating the integration circuit, when each component is designed to be of the same size, the relative accuracy among the components is enhanced. Thus, the circuit is subject to scaling so that the time constant of the integration circuit is all identical. The filter is constituted by having only to couple the loops of the integration circuits by the capacitors.

Title: High-temperature sealing device for heat exchanger of rotary and heat regenerative type
Inventor: FUJIKAWA YASUO
IPC: F28D19/04
Filed: 1983-03-24
Abstract: PURPOSE:To provide in high productivity a high-temperature sealing device for a heat exchanger of rotary and heat regenerative type, not in need of using any sealing material which has sliding property in extremely high-temperature, by cooling the sealing device by letting bypassed low-temperature gas pass through it. CONSTITUTION:A long channel 10 is provided to the sliding surface of a cross rib part 7b of sealing device 7 with a core 1. The part 7b is usually called a cross bar. The sealing device 7 insulates and separates high-temperature gas from low-temperature gas. One end of the long channel 10 is closed, while the other end is opened to the side of a flow path 3 for high-temperature gas by a connecting channel 10a. With such an arrangement, when the core 1 starts rotating, low-temperature gas under high-pressure is fed into the flow path 1a of a core 1 which is composed of fine honeycomb, passing through a flow path 5 for low-temperature gas, being heated, and flowing out of the core 1 into a flow path 6. But part of low-temperature gas is entrapped in the flow path 1a as carry-over gas and flows into the long channel 10. When the core 1 further rotates, the entrapped carry-over gas flows out of the flow path 1a into the flow path 3, because the path 1a is opened to the path 3, as the entrapment by the cross rib part 7b is released. In such a manner the cross rib part 7b of a sealing device can be cooled off by the carry-over gas.
