Abstract: PURPOSE: To obtain a miniature detector of quick response, high detection precision and high reliability by preventing an ambient temperature from affecting a hydrogen-density detecting heating element whose resistance value varies with a temperature in a vacuum container formed of a hydrogen permeable film.  
     CONSTITUTION: Metal film 32 of nickel, etc., which hydrogen permeates excellently is provided inside of several holes at the tip of vacuum container 31 of hydrogen meter sensor 30. Inside of this film 32, heating element 37 whose resistance varies with a temperature and which forms a bridge circuit and coil-shaped temperature compensating resistor 33 with the same temperature characteristics as those of heating element 37 are provided. In addition, an influence of an ambient temperature is much less than that of heating element 37 because of radiation shielding layer 36 covering the circumference. The amount of hydrogen permeating film 32 can be directly detected by ammeter 45 with high precision, high reliability and quick response through the variation of heating element 37 in proportion to variation in temperature in container 31 corresponding the amount of hydrogen. Further, sensor 30 of this constitution is miniaturized.

Filed: 1990-04-24
Abstract: PURPOSE:To enhance cooling efficiency of stator by projecting a plurality of fins from the reaction plate of a carrier truck and setting the angle of the fins such that the air is directed toward the stator of linear motor when the carrier truck runs. CONSTITUTION:A plurality of fins 38, 38 are projected from the side face at the upper and lower parts of a reaction plate, arranged vertically at the lower part of a carrier truck 3, at such positions as the stator of motor or the frame of travel path is not brought into contact.

Title: Magnetic sensor
IPC: G01R33/035
Filed: 1992-04-01
Abstract: PURPOSE:To detect an weak magnetic field with high reproducibility by means of a small element by changing the cross-sectional area of an oxide superconducting material having a layery crystal structure in the C-axis direction and measuring the variation of a resistor in magnetic field while an electric current is made to flow in the C-axis direction. CONSTITUTION:The cross-sectional area of a single-crystal oxide superconducting material 1 in the plane perpendicular to the C-axis of the material 1 is gradually reduced in the C-axis direction and electrodes 4 and 5 are respectively connected to the end faces 2 and 3 of the material 1. When an electric current is made to flow between the electrodes 4 and 5 in the C-axis direction, the current density becomes higher inversely proportional to the cross-sectional area from the end face 3 to the end face 2. As a result, when a magnetic field is impressed upon a sensor cooled to a temperature lower than its critical temperature while a superconducting current is made to flow to the sensor, the superconducting state is broken to a normal conducting state, with the required intensity of the magnetic field becoming smaller in inverse proportion to the current density. Therefore, when the resistance between the electrodes 4 and 5 is measured 6, the extent of the normal conducting state formed in the superconducting material 1 can be recognized and, when the intensity of the magnetic field and the resistance value are found in advance, the intensity of the magnetic field can be found by measuring the resistance.
