Title: High-sensitivity optical frequency discriminator
Inventor: OTSU GENICHI
IPC: G01J9/00
Filed: 1990-03-29
Abstract: PURPOSE:To perform high-sensitivity discrimination by supplying an optical path difference to one projection light beam of a Fabri-Perot resonator which has a polarizing element rotating the plane of polarization of incident light, and separating its passing light, and obtaining the differential output of a photodetector corresponding to its interference light. CONSTITUTION:Two reflected output light beams which are projected from the Fabri-Perot resonator 7 and have orthogonal planes of polarization are reflected at right angles to the incident light and given a pi/2 optical path difference through a 1/4-wavelength plate 2; and the light is split by a polarization beam splitter 3 into two interference light beams, which are guided to photodetectors 4 and 5. The outputs of the elements 4 and 5 are connected to the plus and inverted input terminals of a differential circuit 6 and a differential output is led out. The outputs of the elements 4 and 5 are different in sign from each other, so an output which is double as large as usual is obtained from the circuit 6 and this output becomes the optical frequency discrimination curve of the resonator 7.

Title: Superconducting current limiter
IPC: H01B12/02
Filed: 1992-03-06
Abstract: PURPOSE:To make it possible to return a superconducting current limiter to the low impedance state immediately after releasing the ground fault point by connecting a switch in series to a non-inductively wound superconducting coil, detecting a current flowing through a current-limiting main coil and providing a detect/control portion for switching and controlling the switch based on the current value detected. CONSTITUTION:If a detection control portion 5 detects a current Ib which commutated to the side of a main coil 3 for current limiting due to a ground fault overcurrent, the detection control portion 5 controls a switch 4 to open state, releases the overcurrent state at a non-inductively wound superconducting coil 2, and resets the superconducting coil 2 from normal conducting state to superconducting state. If the electrical system resets to normal state by the separation of the ground fault point and the current Ib flowing through a current-limiting main coil 3 decreases, then the detection control portion 5 detects it, controls the switch 4 to closed state, and returns the superconducting current limiter 1 to low impedance state. By doing this, a sound system can be immediately operated continuously after the release of the ground fault point.
