Title: Electroluminescent float
Inventor: SAKUTA KOJI
IPC: A01K93/00
Filed: 1987-11-27
Abstract: PURPOSE:To provide the title maintenance-free float with high reliability without requiring cells, by providing a room-temperature superconducting coil, permanent magnet and light source, pairing the room-temperature superconducting coil with the permanent magnet, generating electric power with wave power and lighting the light source with the electric power. CONSTITUTION:This float is equipped with a room-temperature superconducting coil 1, a permanent magnet 7 and a light source 3. That is the electroluminescent float is vibrated with wave power to move the permanent magnet 7 in a coil holder 2. An induced electromotive force is produced in the coil 1 by the change in magnetic fluxes thereof. The light source 3 connected through a lead 4 to the coil 1 is lit by the induced electromotive force. Since the coil 1 is constituted of a material assuming superconductivity at ordinary temperature, no voltage drop is caused by the resistance of the coil 1 and the inner wall of the coil holder 2 and the permanent magnet 7 are always kept at a constant interval by the Meissner effect. Thereby the permanent magnet 7 is always smoothly moved without a catch on the inner wall of the holder 2 by side waves. As a result, the maintenance-free float with high reliability is provided without requiring cells.

IPC: G01B17/00
Filed: 1987-12-01
Abstract: PURPOSE:To improve the precision in locating a position wherein a partial discharge is generated, by detecting an acoustic signal derived from a sound wave in a frequency region wherein the speed of propagation of the sound wave generated by the partial discharge is fixed substantially. CONSTITUTION:A sound wave due to a partial discharge generated inside a tank 14 of a gas-insulated switching apparatus is propagated along the wall of the tank 14, detected as an acoustic signals by an acoustic signal detector 2a and 2b and amplified by amplifiers 4b and 4c respectively. Out of the amplified acoustic signals, subsequently, only those of a frequency in a region wherein the speed of propagation is fixed are passed irrespective of the product of the frequency of an A0 mode and the thickness of a plate, and are subjected to A/D conversions 10a and 10b. Meanwhile, an electric signal generated substantially simultaneously with the partial discharge is detected by an electric signal detector 1 and amplified 4a. Then, it triggers a data memory 11 and thereby the sound signals subjected to the A/D conversions are stored. Next, an arithmetic unit 12 subjects the sound signals to an averaging processing synchronously with the electric signal so as to improve S/N, determining a time required for arrival of the sound wave to estimate the position of the partial discharge, and outputting the result thereof to a monitor 13.

Filed: 1987-12-01
Abstract: PURPOSE:To improve the likelihood ratio of identification of information tracks by alternately using a 1st pattern and 2nd pattern for the identification regions arranged in the direction approximately orthogonal with an arraying direction.

Title: Fluorescent lamp
Inventor: MURAYAMA SEIICHI
IPC: H01J9/24
Filed: 1997-11-04
Abstract: PROBLEM TO BE SOLVED: To provide a thin and high output fluorescent lamp by adopting a fluorescent discharge tube having two or more concentrically circular discharge paths on the same plane, and by setting diameters of two discharge tubes forming these two discharge paths within the specific range. SOLUTION: Two ring-shaped discharge tubes 10 and 20 are installed concentrically on the same plane. Discharge spaces of the discharge tubes 10 and 20 are connected with a bridge 1. The electrode 11, the discharge tube 10, the bridge 1, the discharge tube 20 and the electrode 21 are connected through a discharge path in that order. To arrange the two concentrically circular discharge tubes within the same flat plane, these discharge tubes should be processed with high precision to form truly circular ring shapes. If the tube diameter of the discharge tube is more than 25mm, the processing of truly circular ring-shaped glass encounters difficulties, and if the tube diameter thereof is less than 10mm, the glass mechanical intensity is decreased. Therefore, the optimum tube diameter of the discharge tube ranges between 10mm and 25mm.
