IPC: H01H1/26
Filed: 1990-10-01
Abstract: PURPOSE:To maintain an operational condition of a contact point for a constant period and prevent an erroneous operation due to instant stopping, etc., by installing a circuit to delay the discharging of a capacity variable-type capacitor composed of driving electrodes consisting of a movable electrode and a fixed electrode. CONSTITUTION:A switching device is composed of a substrate 1 and a movable device 3 mounted and fixed on the substrate. The movable device 3 is composed of a frame 4, a rectangular movable plate 5, and beams (holding parts) 6a, 6b, with which the movable plate 5 is fixed in the frame 4 and enabled to become twist-deformable, and prepared unitedly from a silicon plate. Further a circuit for delaying the discharging of a capacity variable-type capacitor composed of fixed electrodes 12a, 12b, 13a, 13b and a movable plate 5 is installed. In this case, a contact point is driven by applying voltage to the capacity variable-type capacitor. Consequently, even when the driving voltage is lowered for an instant, electricity application state of the contact point is maintained for a constant period.

Title: Numerical controller
Inventor: SUZUKI HIRONORI
IPC: G05D3/12
Filed: 1988-10-17
Abstract: PURPOSE:To enable accurate machining by setting and adjusting a position loop gain for each motor rotating direction. CONSTITUTION:When a position droop 7 is formed, a polarity decision circuit 16 decides the polarity of the position droop 7. Then when the decided polarity of the position droop 7 is positive, the position droop is multiplied by a preset position loop gain 17 for the positive polarity and when it is decided that the position droop is minus or zero, the position droop is multiplied by a preset position loop gain 18 for the negative polarity or zero. Then the value passed through this process is passed through a DA converter 9 as before to operate as a conventional speed command. Thus, the position loop gain is adjusted by the polarities of the position droop, i.e. the polarities of command pulses. Consequently, the unbalance between the + and - position loop gains is eliminated to improve the control accuracy.

IPC: H01L29/786
Filed: 1986-10-31
Abstract: PURPOSE:To ensure prevention of a back channel, by projecting laser light on a polycrystalline or amorphous semiconductor layer, and recrystallizing the semiconductor layer again. CONSTITUTION:An SiO2 film 11 is formed on an Si substrate 10. After a resist film 12 is deposited, an opening part is formed by patterning. Arsenic ions (As<+>) are implanted in the surface of the SiO2 film 11 through the opening part. Thereafter phosphorus doped polycrystalline Si film 14 is formed. Laser light (a) is projected from above and the polycrystalline Si film 14 is fused. Then, a recrystallized n-type Si layer 15 is formed. At this time, the arsenic ions (As<+>), which are implanted into the surface of the SiO2 film 11, are activated and distributed again on the side of the n-type Si layer 15. Thus a high concentration n-type region 16 is formed at an interface of Si/SiO2. In this way, leaking currents due to a back channel in an MOSFET can be prevented.

Title: Cross-member
Inventor: NAKAJIMA YASUHIRO
IPC: B62D21/00
Filed: 1992-09-30
Abstract: PURPOSE:To provide a cross-member capable of obtaining a high rigidity without increasing the weight of a vehicle body remarkably and also necessitating an additional man-hour. CONSTITUTION:The junction of a lower cross-member 14 with an upper cross- member 16 at the lateral inside of an extension member 10b extending from the end of the cross-member toward the front of a vehicle body is made by a lap joint method. Due to this, even if a horizontal bending stress is produced in the extension member 10b by a load applied from the lower arm, it can be prevented that a crack due to stress concentration is generated in the base end at the lateral inside of it. The splicing of a lower arm bracket 18 positioned at the top of the extension member 10b from the lower-cross member 14 with the upper cross-member 16 at the lateral inside of it is made by the flange joint method. Thus three members to maintain the joint strength against a vertical input load are joined together through a lower arm gusset 20.

Title: Detecting method for plate steel material meandering quantity
Inventor: WAKUZAWA KUNIAKI
IPC: G01B21/06
Filed: 1986-11-05
Abstract: PURPOSE:To improve the accuracy of the product width size by providing detecting means detecting the edge position of a plate steel material at two places respectively in the travel direction of the plate steel material and using the difference between detected results of both detecting means as the meandering quantity of the said plate steel material. CONSTITUTION:Edge sensors 21, 22 are fitted apart from a milling cutter 2 by distance 2L, L respectively. The movement of the plate steel material 1 of an edge mirror main body 3 in the travel path width direction (Y-axis direction) is performed by operating a cylinder 4 based on the information from a detector 11 and two edge sensors 21, 22 fed to a controller 7. The edge sensors 21, 22 detect the same edge section of the traveling plate steel material 1 at their installation positions. If a difference occurs between values of two edge sensors 21, 22, the difference is judged to be the meandering quantity in the distance L, the information on this difference is held in the distance L then fed to a servo valve 5 to operate a cylinder 4. As a result, cut quantities of the plate steel material 1 on both ends can be correctly controlled, and quality can be improved.
