Title: Optical isolator
Inventor: SHIRAI KAZUSHI
IPC: G02B6/42
Filed: 1991-05-28
Abstract: PURPOSE:To facilitate adjustments of optical components by arranging two magnetooptic elements which are arranged in permanent magnets between two birefringent plates and two polarizing elements which differ in polarized wave cutoff direction by about 90 deg. between the magnetooptic elements in parallel to each other. CONSTITUTION:Between the two birefringent plates 24 and 25 which separate or couple optical paths of light having mutually orthogonal planes of polarization, the two magnetooptic elements 28 and 29 which are arranged in the permanent magnets 30 and 31 with Faraday rotational angle made about by 45 deg. are arranged in series. Further, the two polarizing element 26 and 27 which differ in polarized wave cutoff direction by about 90 deg. are arranged in parallel between the magnetooptic elements 28 and 29 with the separation center of the optical paths by the birefringent plates 24 and 25 as a boundary. Consequently, the optical isolator which does not depend upon the polarizing direction of incident light is constituted. Therefore, the adjusting operation for the optical axis directions of the birefringent plates which is essential and difficult in conventional constitution is substantially unnecessary and high isolation is obtained by easier adjusting operation.

Title: Suction/exhaust type combustion device
Inventor: IWANAGA MASAZUMI
IPC: F23N5/24
Filed: 1983-08-22
Abstract: PURPOSE:To maintain a consistent burning state even during the operation of a fan, by providing a pressure sensor adapted to detect the blockage of exhausting combustion gas due to a reverse wind and turn a fan into a high speed operation. CONSTITUTION:A fan 10 runs at a slow speed while a burner 4 burns a small quantity of fuel. As the fan 10 provides only a small delivery pressure, the exhaust of combustion gas is blocked to increase the internal pressure of body 1 upon the actuation of fan. Upon the body 1 having its internal pressure raised in excess of an external pressure, the diaphragm 13 of pressure sensor 12 is urged downwardly against a spring 18 to lower an operating lever 19 jointly. The lowering movement of operating lever 19 causes a micro-switch 20 to close its contact and a controller 21 to turn the fan 10 into a high speed operation. The exhausting force of combustion gas is thus increased. Upon the combustion gas being properly exhausted and the body restoring its internal pressure to normal value, the fan 10 resumes its normal operation.

Filed: 1999-05-31
Abstract: PROBLEM TO BE SOLVED: To enable an ISDN channel repeater, which connects an emergency informing device for analog channel to an ISDN channel to faultlessly and preferentially receive a returned message from the incoming destination after the emergency incoming device sends a report message to the destination, even when the terminal for the ISDN or another terminal for analog channel makes channel capture operations. SOLUTION: Upon detecting that an emergency informing device is in a returned-message waiting state, a control circuit 24 disconnects a terminal for ISDN from the ISDN, while maintaining the connection between a terminal adapter section 100 and the ISDN by controlling a channel to forcibly disconnect a circuit section 200. When the channel capture detecting means 18 of a circuit section TAn detects channel capturing operations made from a terminal for analog channel while the emergency information device is in the returned- message waiting state, the control circuit 24 controls the circuit section TAn so as cause a busy tone to be sent to the terminal for analog channel.
