Title: Analog/digital converting circuit
Inventor: NODA TSUTOMU
IPC: H03M1/54
Filed: 1983-04-15
Abstract: PURPOSE:To obtain a circuit which can be easily incorporated into an integration circuit and compensates automatically the DC offset of an integration type A/D converter, by detecting digitally the DC offset and controlling a counter by the value of the DC offset. CONSTITUTION:A D/A conversion is applied first to a voltage source 11, and the difference from the ideal value is stored in a memory 15 in the form of a DC offset error. Then a digital comparator 16 compares the output of a counter 12 with the value corresponding to the error of the memory 15 when an A/D conversion is applied to the analog input of an input terminal 1. The counter 12 is reset when the value of the counter 12 is equal to the error of the memory 15, and the counting action of the counter 12 is started again and continued until the output of an analog comparator 6 is inverted. This count value is delivered in the form of the digital value. This digital output is turned into a digital output whose error component is compensated since the restart of the counter 12 is delayed by an amount equivalent to said error component.

Title: Measuring device for expansion strain of hydrogen occlusion alloy
Inventor: SAITO TAICHI
IPC: C22C19/00
Filed: 1995-03-24
Abstract: PURPOSE: To enable the expansion strain of hydrogen occlusion alloy to be measured safely in a short time by using a thin wall hydrogen occlusion alloy charging vessel, external pressure vessel and heating and cooling device. CONSTITUTION: A hydrogen occlusion alloy charging vessel 52 provided on the surface with a strain sensor 55 is placed with seal in an external pressure vessel 51. A hydrogen introduction/derivation pipe 57 for the vessels 51 and 52 to introduce and derive hydrogen is arranged. A device for cooling and heating the hydrogen in the pipe 57 is placed outside of the vessel 51 and the thickness of the vessel 52 wall is made 0.1 to 2mm. By making the pressure in the vessel 51 and the pressure in the vessel 52 equal, the pressure of hydrogen is not loaded on the hydrogen occlusion alloy charging vessel wall and the wall thickness of the vessel 52 can be made thin. Thus, the effect of expansion strain of the hydrogen occlusion alloy can be sensitively measured.  As the alloy is sealed in the vessel 51, the scatter of the alloy is prevented by the vessel 51 even in the case of vessel wall failure owing to alloy expansion. The heat during occluding hydrogen is removed by introducing cold hydrogen in the vessels 51 and 52 during introducing hydrogen.

Title: Optical sensor for detecting temperature
Inventor: GOTOU AKIYA
IPC: G01J5/08
Filed: 1979-05-29
Abstract: PURPOSE:To detect temperature of a motor or the like without affection of a strong electromagnetic field by connecting a sensor that consists of a rod lens, polarizer plate, temperature dependent double refraction crystal, wavelength plate and reflection body to the tip end of an optical fiber. CONSTITUTION:Light beam incident from the optical fiber 1 is diffused in the focusing rod lens 2 of 1/4 pitch so that the beam diameter may be expanded, and is made parallel to apply itself to the polarizer plate 4. Only the polarized component that agrees with the direction of polarization is taken by the polarizer plate 4 and applied to the double refraction crystal 5. The light beam is divided into an ordinary ray and an extraordinary ray and a retardation is developed because the C-axis of the double refraction crystal 5 is shifted from the direction of polarization of the polarizer plate 4. When the light ray moves back and forth in the wavelength plate of 1/4 pitch and passes through the double refraction crystal 5 again and reaches the polarizer plate 4, an elliptic polarization is produced, only the component that agrees with the direction of polarization of the polarizer plate 4 is taken.
