Title: Method of detecting excessive temperature for sensor and sensor using the same
Inventor: TOYODA HIDEKI
IPC: G01K11/12
Filed: 1993-04-28
Abstract: PURPOSE:To enable the detection of degrading in characteristic and the presence of a breakage owing to an abnormal rise in the temperature of a sensor only with observation from outside by applying a thermopaint on a circumferential surface as varying reversibly in color near a specified temperature. CONSTITUTION:Thermopaints 40a and 40b are painted on a side 34 of a metal cap 33 of a pressure sensor and on a smooth surface of a cylindrical seating surface 43 near the side of a piezoelectric element 11. The thermopaints 40a and 40b are composed mainly of organic and inorganic salts and a double salt of heavy metal such as Ni, Co or Pb varying reversibly in color near a specfied temperature. The material discharges a gas of CO2, SO2, NH3 or the like at a specified temperature or causes an oxidization, decomposition and the like and discolors depending on the temperature as a result of such a chemical reaction. Thus, with the arrangement of the thermopaints 40a and 40b, an abnormal rise in the temperature is judged to be the cause from any change in color of the thermopaints 40a and 40b in case malfunctioning of a pressure sensor occurs. Otherwise, it is attributed to another cause.

Title: Measuring method for optical disk characteristic
Inventor: ITO SHO
IPC: G11B7/26
Filed: 1987-05-27
Abstract: PURPOSE:To accurately measure the up-down deflection quantity and tilt angle of a disk by irradiating a guide track part of the disk with laser light and detecting variation in the direction of diffracted light. CONSTITUTION:The laser light 3 is made incident on a disk guide groove part 2 formed in the disk almost at right angles to the disk, light position detectors 5L and 5R are placed at left and right diffracted light photodetection positions at the same distance from the incidence position, and their polarities are equalized to that of the side facing the incident laser surface. The outputs of the detectors 5L and 5R are amplified by differential amplifiers 6L and 6R and inputted to an adder 7 and a subtracter 8 to obtain a sum output Va and a difference output Vb. Consequently, the sum output Va and difference output Vb are quantities proportional to the up-down deflection quantity and tilt angle of the disk and the gains of the adder 7 and subtracter 8 are adjusted to find the up-down deflection quantity and tilt angle directly.

Title: Simple-type dust sampler
Inventor: TSUGAWA TOSHIICHI
IPC: G01N1/02
Filed: 1990-05-18
Abstract: PURPOSE:To enable sharp reduction of the weight by rotating a rotary disk at a prescribed speed, by driving a prescribed flow rate of sample air against a dust sticking surface on the rotary disk by a blower and by measuring dust caught and collected on the dust sticking surface, by a radiation detector. CONSTITUTION:A flat rotary disk 1 is fitted to a shaft of a motor 3. An adhesive sheet 2 is stuck on the surface of this disk 1 being opposite to the motor 3, so as to prepare a dust sticking surface. A blower 5 is disposed so that a blowoff port thereof is opposed to the dust sticking surface and that the axial line of the blowoff port is made parallel to the shaft of the motor 3. On the opposite side of the motor 3 to the blower 5, a radiation detector 4 is disposed so that a detecting surface thereof is opposed in proximity to the dust sticking surface. The disk 1 is rotated at a prescribed speed, a prescribed flow rate of sample air is driven against the dust sticking surface by the blower 5 and the dust caught and collected on this surface is measured by the detector 4. When the drive of the sample air is continued, an output of the radiation detector increases with time and saturated after a certain time. The time till it is saturated is in reverse proportion to the concentration of the dust in the air, while the strength of radioactivity measured at the point of saturation is in proportion to the strength of the radioactivity in unit dust. When the time of the saturation and the output of the detector at the time point of the saturation are known, accordingly, the radioactivity in the air can be calculated with ease.

A distance to the inner circumference of the steel pipe P is measured by means of the linear gauge sensor 24 and laser distance meter 25 every time when arms 23a, 23b rotate at prescribed angle, then the measured value is outputted to the operator 35. Thus, the inner diameter and inner circumference length of the steel pipe P can be measured.

Filed: 1992-04-23
Abstract: PURPOSE:To prevent reduction of MnO in molten slag from being reduced and entering molten steel and to easily produce a low-Mn steel by adding a specific quantity of boron oxide into the molten steel at the time of tapping the molten steel from a converter. CONSTITUTION:At the time of tapping the molten steel from the converter after making the molten steel by decarburize-refining molten iron in the converter, the boron oxide is added at 0.5-3kg/ton of the molten steel. Reducing agents such as A, Si, etc., are added at the time of tapping the molten steel because of deoxidation of the molten steel and the adjustment of components, but as MnO in the molten slag has an intense affinity with B2O3 and is combined with B2O3, activity of MnO is rekmarkably lowered. Therefore, Mn reduced with Al and Si do not go into the molten steel, and rather, Mn in the molten steel is oxidized to MnO and removed into the molten slag, and the low-Mn steel is easily and stably obtd.
