Title: Numerical controller for load
Inventor: CHIBA JIRO
IPC: H02P8/36
Filed: 1989-05-29
Abstract: PURPOSE:To rapidly and precisely numerically control a load by setting a counted value in which the driving and stopping points of a load correspond to the moving distance of the load in a counter, and controlling it with remaining counted value when it is subtracted by a position detection signal. CONSTITUTION:A ball screw 4 is driven by the output of a 2-phase reluctance motor H, and a load E is driven by its output shaft. A counted value corresponding to the load E is set in a counter, and the set counted value is subtracted by utilizing the position detection signal of the motor H. The motor H is driven at a high speed in a zone in which the remaining counted value is larger than a first set value, it is converted to a reverse torque to be abruptly decelerated when it reaches the first set value, and it is driven at a constant speed to become a predetermined speed. When the remaining counted value becomes a second set value, it is converted to a 2-phase stepping motor. When the remaining counted value becomes zero, change of an input electric signal for a stepping operation is stopped to stop the motor. Thus, the numerical control of the load E can be rapidly and precisely conducted.

Title: Power steering device
Inventor: SUZUKI KATSUHIRO
IPC: B62D5/083
Filed: 1997-05-07
Abstract: PROBLEM TO BE SOLVED: To improve an assembling property by arranging a pair of spring members to hold both sides of an input shaft on an output shaft or a member integrally rotating with this output shaft and displaying preset force by spring force of this spring member. SOLUTION: An initial load, that is, preset force of spring members 13, 13 works on an input shaft 4. By this amount, neutral rigidity is improved, and steering safety at the time of rectilinear travelling is maintained.

IPC: B23K35/02
Filed: 1981-08-25
Abstract: PURPOSE:To obtain a brazing material which can easily be made into a wire or plate even when plural metal elements lowering workability are contained, by mixing a metal or alloy, which has a melting point lower than that the external circumferential material of a high-melting-point metal or alloy so that the melting point decreases gradually toward the core. CONSTITUTION:For example, a cylinder made of is used as an external circumferential material, and a core material uses tin; and the core material of tin is intruded into the cylinder of copper and then extrusion and wire drawing are performed. When a metal or alloy having a melting point lower than that of the external circumferential material is used, the core material is never melted even when the external circumferential material is melted by external heat during brazing operation. Further, when the core material is heated up to the melting temperature, the external circumferential material is melted more than necessary to flow out to even parts other than a part to be brazed. For this purpose, the melting point is decreased gradually toward the core.

Title: Self-reset type warning device
Inventor: ARINOBU ICHIRO
IPC: G08B17/00
Filed: 1990-05-23
Abstract: PURPOSE:To evade such danger that an abnormal state is left as it is although a warning output is sent out once by providing a warning output stop resetting means which resets a warning output stop state a specific time after a warning output stop means stops the warning output of a warning output means.

Title: Method for growing semiconductor
Inventor: KATOU TAKESHI
IPC: H01L29/812
Filed: 1980-09-25
Abstract: PURPOSE:To prevent occurrence of warping by providing a growth blocking layer on a substrate in a net shape and selectively growing a semiconductor crystal. CONSTITUTION:An SiO2 film 2 is grown on GaAs semiconductor substrate 1. Then a photoresist film 3 is deposited, and unnecessary SiO2 film is removed so that the film 2 is remained in a net shape. Then a GaAs crystal 3 is grown on said substrate 1. After the growth, the net shaped film 2 is removed. The required large area GaAsP crystal is obtained by selecting the width of the net shaped film 2 so that the side of the crystal blocks are not linked by the lateral growth of both sides of the crystal blocks. In this constitution, since the crystal is separated in the blocks, the strain due to the thermal expansion and the like is alleviated by the gaps between the blocks, and the degree of warping becomes small.
