Filed: 1982-12-15
Abstract: PURPOSE:To obtain a compact and light position indicator having a high degree of operability, wherein recording, detection, and erasing are repeated in correspondence with the rotation of a spherical body, and signals indicating the moving distance and the moving direction are outputted. CONSTITUTION:Detecting coils 3-1...3-8 generate detected signals when magnetic poles of a magnetized spherical body 1 pass the front of each coil. When a magnetizing signal S1 (a) is applied to a magnetizing coil 2, the spherical body 1 is magnetized. When a position indicator moves and passes the position of P2, the magnetic pole N of the spherical body 1 passes the front of the detecting coil 3-1. Then a detected signal S3 (c) is generated. The moving distance is a value, which is determined by the arc of the spherical body 1 corresponding to the magnetizing coil 2 and the detecting coil 3-1. The moving direction is the direction, which views the direction of the detecting coil 3-1 at the point P2 from a P1. Immediately after the generation of the detected signal S3, a demagenetizing signal S2 (b) is applied to the magnetizing coil 2, and the magnetic poles N and S, which are generated before, are erased, and the initial coditions are imparted to the spherical body 1.

Abstract: PURPOSE:To improve measurement accuracy by varying the temperature in a heating furnace to specific temperatures and obtaining outputs of detection parts of respective high-temperature strain gauges at respective specific temperatures, and measuring apparent strain due to the temperatures of the high-temperature strain gauges. CONSTITUTION:The strain gauges have tubes 2 as part of their detection parts inserted into a groove part 14b of a fitting base 14 almost without contacting, and a lead line 14b is led out from one end side of the groove part 14b.

Title: Cooling and heating apparatus
Inventor: KOTANI YOSHIHIKO
IPC: G01N25/00
Filed: 1988-09-01
Abstract: PURPOSE:To reduce frosting and the like on an evaporator and the like in a low temperature chamber by providing a valve mechanism which allows exhaustion but inhibits intrusion of gas from the outside at an exhaust path that is connected to at least one of a high temperature chamber and a testing chamber. CONSTITUTION:Dew condensation occurs on a material 10 in a testing chamber 9 and on the wall surface of the testing chamber by low temperature exposure and following normal temperature exposure with introduced outer air. Thereafter the dew drop water becomes saturated steam by high temperature exposure. When the internal pressure in the testing chamber 9 and a high temperature bath 4 exceeds a predetermined constant pressure higher than atmospheric pressure due to the pressure of the steam and the like, a valve mechanism 1 at an exhaust path 2 is automatically opened. A high pressure gas incorporating moisture is exhausted to the outside. Therefore, the possibility of the intrusion of the high pressure gas incorporating the moisture in the testing chamber 9 into a low temperature chamber 6 under low pressure through a gap between low pressure chamber dampers 65 and 66 and a partitioning wall 7 is largely decreased. Thus, frosting and the like on an evaporator and the like in the low temperature bath 6 are decreased by that degree. A defrosting interval is elongated. When the internal pressure of the testing chamber 9 is decreased to the vicinity of the atmospheric pressure, the valve 1 is closed. The intrusion of gas incorporating outer moisture into the test chamber 9 is prevented.

Abstract: PURPOSE:To make it possible to perform accurate inspection without the effects of disturbance light and temperature change by modulating a laser beam so as to decrease the power of the laser beam or to make the power to be zero during one scanning of the laser beam. CONSTITUTION:A laser driving circuit 11 modulates a semiconductor laser 12 constituting a laser light source at a constant period and drives the laser. The circuit 11 forms two clock signals and imparts the signals to a received- light-signal processing circuit 14. The circuit 14 detects the output signal when the power of the laser beam in the output signal of a means for detecting transmitted light or reflected light from a material to be inspected is decreased or becomes zero. The signal is made to be a reference signal. Namely, the circuit 14 receives the two clock signals of a correcting clock and a data clock and processes the electric signal from a photodetector 13 for receiving the reflected light from the material to be inspected. The signal is amplified and binary-coded. The binary-coded signal is imparted to an arithmetic circuit 15, and specified operation is performed. Thus, the presence or absence of the defects, the shapes of the defects and the like in the material to be inspected are judged.
