Title: Ii-vi compound semiconductor light-emitting element and its manufacturing method
Inventor: KURAMOTO MASARU
IPC: H01S5/00
Filed: 1996-09-26
Abstract: PROBLEM TO BE SOLVED: To suppress the increase in crystal defects by providing an active layer that is spatially separated into the recombination region and the non- recombination region of a carrier within an active layer surface. SOLUTION: A layer consisting of ZnCdSe is formed. A square mask pattern is formed by the exposure technology and only a light-emitting region (recombination region) 6 of ZnCdSe is left below a resist by a reactive ion etching. After the resist has been eliminated, it is buried into the surface, thus forming a barrier region (non-combination region) 7 and an active layer 5. By separating the recombination region 6 and the non-combination region 7 spatially within the active layer, the growth of a dark-line defect in <100> direction, generated from a point defect accompanied by a rapid deterioration can be suppressed. This type of deterioration depends greatly on the amount of distortions in the active layer, and the recombination density of carriers and the increase in defect has directivity.  Therefore, by spatially separating the recombination region 6 and the non-combination region 7, increase in defect with directivity can be suppressed.

Title: Circumferential automatic welding equipment
Inventor: WADA SHOJI
IPC: B23K9/028
Filed: 1987-10-12
Abstract: PURPOSE: To perform automatic welding by detecting the pipe diametrical surface in the diametrical direction of a pipe by a position detecting sensor to detect the center of the pipe and moving a welding head by the quantity of correction in the triaxial direction with respect to the detected position and fitting the axial center of the welding head to the axial center of the pipe.  
     CONSTITUTION: A touch sensor 11 is pushed forward from the welding head 12 by a cylinder 19 and the touch sensor 11 is inserted into the pipe 2 by turning a feed screw 16 in the Y axial direction by driving a motor 15. Next, a feed screw 14 in the X axial direction is turned and the touch sensor 11 is moved on right and left to measure the inner diameter of the pipe 2 and fixed on its central position. In the same way, the central position of a Z axis is detected to complete the centering work of the pipe 2. The cylinder 19 is actuated to bring back the touch sensor 11 to the rear from the welding head 12. The welding head 12 is moved to the central position of the pipe 2 found by the centering work by a triaxial positioning controller and an electrode 6 is rotated with the axial center of the welding head 12 as a center to perform the welding.

Filed: 1996-09-26
Abstract: PROBLEM TO BE SOLVED: To provide a disk rotating drive device capable of preventing a center ring from holding onto a motor rotating shaft at the time of sliding the center ring for the purpose of chucking a disk. SOLUTION: The disk rotating drive device 1 has a motor main body 2 and a chucking mechanism 3 capable of holding the disk D to be in the state of being rotatably driven by the motor main body, and the chucking mechanism 3 is operated for the purpose of chucking the disk by sliding the center ring 32 along the motor rotating shaft 52. A shaft hole 32b of the center ring 32 is equipped with an inner circumferential surface 32c set to surface roughness capable of preventing the center ring from holding onto the rotating shaft 52 at the time of sliding along the rotating shaft. This surface roughness of the inner circumferential surface 32c is set to a value to fall within a range from 1.3μm to 3.0μm at the max. roughness (Rmax). As a result, holding onto the center ring can be prevented, and at the same time, its backlash can also be suppressed to fall within an allowable range.

Title: Driving control device of motor-driven object for vehicle
Inventor: MONZEN TOMOAKI
IPC: E05F15/20
Filed: 1995-10-02
Abstract: PROBLEM TO BE SOLVED: To easily detect a movement by manual operation by providing a control means for determining the driven direction of a DC motor from induced electromotive force appearing on a pair of terminals of the DC motor driven in accordance with the moving direction of a motor-driven object to drive the DC motor in a predetermined direction on the basis of the result. SOLUTION: In a detection circuit 2 connected to a terminal T1, when a slide door is opened or closed by manual operation, so that an electric motor M is forcibly rotated in the regular direction or in the reverse direction, the voltage of the terminal T1 due to induced electromotive force is amplified by an operational amplifier OP and compared with a reference voltage by a comparator CMP. When the slide door is closed, so that the terminal T1 has a higher potential than that of a terminal T2, the output of the operational amplifier OP exceeds the reference voltage of the comparator CMP and a transistor Tr is turned off and the input terminal P1 of a microcomputer 1 for control has 'L' level. To the contrary, when the terminal T2 has a higher potential than that of the terminal T1, the input terminal P1 remains unchanged and kept 'H' level.

As a result, the delivery port surface 1a is prevented from being rubbed with the carriage guide surface 4g. The delivery port surface 1a and delivery ports provided on the delivery port surface 1a are protected.

Filed: 1990-09-25
Abstract: PURPOSE:To improve the yield of a magnetic head to be obtained by manufacturing the thickness of a soft magnetic thin film so that the other end opposite to a sliding surface end is thicker than the sliding surface end. CONSTITUTION:The magnetic head is equipped with a substrates 1a and 1b provided with a sliding surface 12 with a magnetic recording medium, a groove 5 formed in the substrates 1a and 1b adjacent to the sliding surface 12 and soft magnetic films 2a and 2b made along the wall surface of the groove 5, and constituted to form a gap opposing the respective soft magnetic thin films 2a and 2b by a pair of substrates 1a and 1b. The thickness of the soft magnetic thin films 2a and 2b is made so that the other end opposite to the end of the sliding surface 12 is thicker than the sliding surface end. Thus, since the mutu ally opposing areas of opposite each soft magnetic thin film are increased than before, even if the deviation of the soft magnetic thin film due to the variation of the working accuracy of a manufacturing process is generated, a magnetic circuit bigger than heretofore can be obtained. Therefore, the reduction of the efficiency of the magnetic circuit constituted by the opposite soft magnetic films is controlled.

Abstract: PURPOSE:To exactly and speedily check whether a cover switch is normally reacts or not by providing a checking means to be operated with a condition that the specified operation of a manual switch is executed and to drive an announcing device in correspondence to the switch operation of a cover switch. CONSTITUTION:A microcomputer 36 executes a checking program when the specified operation of various switches 14-20 is executed. Namely, the checking means is operated. In a condition that this checking means is operated, when a cover 10 is opened by a check worker, a cover switch 11 is turned off in a certain open angle position.
