Title: Gaas substrate and its production
Inventor: SHIMAKURA HARUTO
IPC: C30B29/42
Filed: 1995-03-16
Abstract: PURPOSE: To obtain a GaAs substrate wherein the concentration of EL2, an inherent defect placed at a deep position, is higher at a place near the surface of a thin substrate than at its inner place, by annealing a GaAs wafer at two stages whose conditions are different from each other. CONSTITUTION: In the first annealing stage, a wafer cut out from a GaAs single crystal is vacuum-sealed in a quartz ampule together with a suitable amount of arsenic and subsequently held in the atmosphere of an arsenic pressure of 0.8 times or higher a stoichiometric equilibrium steam pressure at a temperature of 1000-1100 deg.C for a prescribed time (e.g. 2hr). In the second annealing stage, the treated wafer is cooled to 400 deg.C, held in the atmosphere of an arsenic pressure of 2 times or higher the stoichiometric equilibrium stream pressure at 800-1000 deg.C for a prescribed time (e.g. 3hr), and subsequently cooled to room temperature. In the obtained GaAs substrate, the concentration of EL2 is higher at a place near the surface than at an inside place, and the EL2 concentration at a place deep by at least 60μm from the surface of the substrate is >=1.6×10<16> cm<-3> .

Abstract: PURPOSE: To facilitate the forming process for key grooves through which a disk plate is engaged with an output shaft connected with an engine and to prevent oil from flowing into the clutch by a method wherein one of the key grooves is employed as an outlet of oil leaking from the engine.  
     CONSTITUTION: On a powered lawn mower, when an operating lever 111 is revolved in a desired direction, its bent parts 11a, 11a push a pressure plate 6 downward against a spring 9. Accordingly, a clutch spring 35 expands, the clutch plate 26 and the disk plate 15 are connected in a unitary body and a working cutter 40 is turned by the rotation of the output shaft 4. In said clutch mechanism, on the collar member 13 attached to the disk plate 15 are formed two pairs of slits 14, 14 from a long cylindrical part 13a to a flange part 13b and when they are choked by a stopper 16 fixed to the collar member 13, key grooves 13d are formed.

Filed: 1988-03-11
Abstract: PURPOSE:To keep a conforming member from being positioned in a side aligning position while a bin is moving to prevent the disturbance of the conformation of sheets by providing a conforming member movement control means for controlling a conforming member driving means. CONSTITUTION:A bin unit 9 has a number of bins B while having a conforming rod 43 which is moved centering around a moving center shaft 42. At the time of conforming sheets, the conforming rod 43 is moved from the home position to a side aligning position 43a which is determined in line with the size of the sheets and brought into contact with the end portions of the sheets to conform the sheets in cooperation with a conforming reference board 41 and, then, moved to a standby position 43b to be on standby for the conformation of the following sheets. Even if the conforming member 43 has started to move to the side aligning position 43a to carry out the conformation of the sheets, it arrives at the side aligning position 43a after the movement of the bin B is stopped without arriving at the side aligning position 43A at least while the bin B is moving, and without completing the conforming action. After the movement of the bin B is stopped, the conforming member 43 arrives at the side aligning position 43a to conform the sheets in the side aligning position 43a.

Filed: 1993-03-18
Abstract: PURPOSE:To prevent discharge from occuring, measure a potentialat a small region in noncontact state, and achieve miniaturization of the device by providing a measurement probe, an electrical element, and a charge measurement means. CONSTITUTION:After a measurement probe 1 is brought closer to the object at the grounding potential, the probe 1 is brought closer to a potential measurement surface 2. At this time, the charge determined by air between the probe 1 and the measurement surface 2 and the amount of static electricity of an electrical element 3, the potential, etc., of the measurement surface 2, flows into or flows out of the measurement surface 2 via an element 3, the probe 1, and an insulation substance 1a from a constant potential source 4. A charge measurement means 5 measures the potential of the measurement surface 2 by detecting the amount of charge entering or escaping from the element 3. The substance 1a is sealed to the tip of the probe 1, thus preventing discharge and measuring the potential of a small region without any contact. Also, since the configuration of the probe 1 is extremely simple, the device can be miniaturized easily.

Abstract: PURPOSE:To produce simply and easily a bearing having excellent shape accuracy and strength in the stage of producing a long shaft-shaped bearing provided with a bulge in the middle part by using a core pipe having the final shape made of a shape memory alloy. CONSTITUTION:A core pipe 6 for a bearing having parts for supporting a shaft at both ends 6a and a bulge 6 in the middle is manufactured of a shape memory alloy. Said pipe 6 is put into the molding space 11 of molding dies for the bearing 7 constituted of an upper die 8, a middle die 9 and a lower die 10 and a sintering metal as a raw material for the bearing is packed between the pipe and the inside wall of the molding dies to form the bearing 7. The raw material is then sintered so that the bulge 6 of the pipe 6 is restored to the original shape by the heat thereof to straighten the same. The core pipe is thus easily removed from the bearing 7. The bearing 7 of long shaft shape having journal parts 7a, 7b at both ends and a part 12 which is a large-diameter recess and does not contact with the shaft in the middle part is thus easily produced. Since there is the extremely thin-walled part in the large-diameter recess, the bearing having excellent strength is obtd.

Title: Travel measuring method
IPC: G01B21/00
Filed: 1991-03-22
Abstract: PURPOSE:To enable it to measure the extent of more than resolution in a measuring instrument by shifting a direction of actually measuring the travel of an object by an angle theta, and measuring the travel of the object in relation to a direction to be measured by this measuring value and the angle theta. CONSTITUTION:In this method, there are provided a Y-axis slide 2 for shifting a work table 1 in the Y-axis direction and an X-axis slide 3 for shifting the table 1 in an X1-axis direction tilted as far as an angle theta to an X axis orthogonal with a Y axis. Suppose the table 1 is shifted by a size A on the x1 axis, the value to be actually known is an amount of travel B along the X axis, so that this travel B is found as B=AXcostheta. In this connection, the size A is the value measured by a linear scale head. Thus, as compared with the case that a linear scale is installed in the X-axis direction and measured, the extent of resolution is improved by a portion for costheta. In addition, since the table 1 shifts by C=AXsintheta even in the Y-axis direction, it is compensated by this value C in the Y-axis direction and thereby a precision movement can be done in the X-axis direction.
