Title: Detector for position and speed
Inventor: UZUKA MITSUO
IPC: G11B15/467
Filed: 1981-12-30
Abstract: PURPOSE:To integrate a speed detecting section and a position detecting section  of a VTR or the like to enable the detection in a small size and at a high accuracy by magnetic detection of a frequency signal corresponding to the relative  moving speed between two objects moving relative thereto and reference position signals indicating relative reference positions depending on the magnetic fields of the signals magnetized on common signal tracks. CONSTITUTION:A frequency signal FG is induced between output terminals of a first detection coil section and a phase signal PG between output terminals of the second detection coil section by relative movement of an FG magnet 48 and FG coil 51. The use of the FG coil 51 having a wavelength selectivity allows the detection of magnetic fields of signals for the frequency signal and the phase signal on the same signal track in respective detection coil sections of the FG coil 51 by means of an FG magnet. In addition, the frequency signal FG obtained by the first detection coil provides a highly accurate speed information as any error in the magnetization pitch lambdaM of the first magnetized surface of the FG magnet 48 is equalized.

IPC: G01B11/00
Filed: 1988-08-29
Abstract: PURPOSE:To measure the quantity of eccentricity of the body existing in a glass pipe with respect to said pipe by a method wherein an object to be measured wherein the body is provided in the glass pipe is passed between a light projector and a photodetector to measure the output voltage of a sensor, and the center position of the glass pipe and that of the body are calculated from the relation between the position of the object to be measured and the output voltage of the sensor. CONSTITUTION:An object 3 to be measured wherein a body 2 is provided in a glass pipe 1 is placed on a moving table 4 at a predetermined position and the moving table 4 is subsequently fed at a predetermined pitch to allow the object 3 to be measured to pass between the light projector of a transmission laser type sensor 5 and a photodetector 7. As a result, the output voltage of a straight line part appears at the position in the vicinity of the outer diameter of the glass pipe 1 and that of the body. From this straight line part, the imaginary outer diameter of the glass pipe 1 and that of the body 2 can be respectively calculated. Since the center position of the glass pipe 1 and that of the body 2 are respectively calculated from said imaginary outer diameters, the quantity of eccentricity of the body 2 to the glass pipe 1 is calculated as a numerical value.

IPC: E01C3/00
Filed: 1993-08-27
Abstract: PURPOSE:To obtain a base course material based on steelmaking slag. CONSTITUTION:A process for producing a base course material based on steelmaking slag, comprising adjusting the basicity (CaO/SiO2) to 2.0-5.0 by a weight ratio in the manufacture of steel iron, adding fluorite and/or calcium chloride to the mixture, cooling the mixture, spontaneously aging this mixture under an atmospheric pressure, crushing the cooled slag, adjusting the particle size of the crushed particles, and forcibly aging these particles by blowing steam into them under an atmospheric pressure. In this process, the spontaneous aging may be preceded by the crushing and the particle size adjustment. The base course material produced by either of these processes may be mixed with blast furnace slag and/or waste concrete to produce a mixed slag-based base course material. Thus, the base course materials can be produced at good efficiency within a short time from steelmaking slag.

Title: Simulation device
Inventor: TERANISHI KUNIO
IPC: G09B9/00
Filed: 1990-08-13
Abstract: PURPOSE:To obtain such a structure that tensile loads do not act on a spherical bearing by interposing between one of sliders and an oscillation stand a bearing case which holds the spherical bearing in such a manner as allowing the spherical bearing to freely slide in its horizontal direction within a predetermined area. CONSTITUTION:An oscillation stand 1 is urged to heave by causing hydraulic cylinders 12 disposed on the right and left sides of the oscillation stand 1 to expand and contract simultaneously. Thereby right and left sliders 4 each rise and fall along a shaft 2 and vertically drive the oscillation stand 1 integrally therewith. Then each hydraulic cylinder interposed between each slider 4 and the oscillation stand 1 is vertically moved integrally with the oscillation stand 1. Should synchronization error occur between the two expanding and contracting hydraulic cylinders 12, the oscillation stand 1 is tilted and time distance between the oscillation stand 1 and the spherical bearing 6 is increased. In such a case the spherical bearing 6 spline-coupled to the inside of a bearing case 5 is slid leftward so as to cancel out the increase of the distance. Therefore tensile loads do not act between the oscillation stand 1 and each slider 4 even with the syncronization error of the hydraulic cylinders 12 and a member such as the spherical bearing 6 interposed between the oscillation stand 1 and each slider 4 is in no danger of being damaged.
