Title: Drag current controller for electromagnetic clutch
Inventor: MIYAWAKI MOTOHISA
IPC: B60W10/101
Filed: 1985-06-27
Abstract: PURPOSE:To achieve smooth starting, in a transmission system where an electromagnetic clutch is combined with a stepless belt transmission, by flowing the drag current to the electromagnetic clutch only under quite low speed including stoppage upon opening of travel range accelerator. CONSTITUTION:Upon reaching of vehicle speed detected through a vehicle speed sensor 50 to V1 which will show the border between the direct-coupled region and released region of clutch under traveling of vehicle, power supply to the clutch coil 8 of electromagnetic powder clutch 1 is interrupted through a control unit 2 thus to disconnect the clutch 1. While upon reaching to V2 where the vehicle will almost stop, the drag current corresponding with the output from a line pressure sensor 54 for detecting the line pressure PL in the hydraulic system of stepless transmission 2 will flow into the coil 8 thus to produce slight drag torque in the clutch 1. Since said drag torque is set with correspondence to the static frictional torque when starting the belt of stepless transmission 2, smooth starting can be achieved.

Title: Trimming unit
Inventor: SUGIHARA KAZUYOSHI
IPC: H01L21/67
Filed: 1985-06-27
Abstract: PURPOSE:To accomplish high-precision positioning by a method wherein a displacement gauge accurately determines the position of a trimming mechanism and the difference between the actual position signals and target position signals is fed back into a controlling unit for the actuating of driving members. CONSTITUTION:A closed loop servo is constructed for the actuation of a trimming mechanism. The attitude of the trimming mechanism is determined by an eddy current type non-contact displacement gauge 41 detecting the positions of the X, Y and theta axes of the trimming mechanism. The detected signals are amplified by a pre-amplifier 42 and then digitized in an AD converter, whereafter they are applied to a comparator 44. Target position signals yielded by a computer 45 are also applied to the comparator 44. A controlling circuit 46 goes into operation and actuates driving members 6-9, which continues until the difference is small enough to fall within the range of tolerance outputted by the computer 45. This neutralizes the interference with each other of the three axes in a trimming mechanism, and allows the trimming mechanism to accomplish its inherent long-stroke movement and high-precision positioning.

Title: Crystal vibrator
Inventor: KOMATSU CHUICHI
IPC: H03H9/13
Filed: 1992-06-02
Abstract: PURPOSE:To improve the soldering strength by plating silver onto the surface of solder on a lead wire of a crystal vibrator, heating the vibrator to a temperature of 200-290 deg.C so as to diffuse the silver onto the soldering surface. CONSTITUTION:A lead wire 4 formed by barrel-plating copper and solder to nickel silver is subject to film forming of silver by flash plating by nearly 100A. The lead wire 4 is welded to an electrode part 3 formed by film-forming chromium and silver to a crystal 1 by the vapor-deposition method with hot air. When the temperature is 200 deg.C or below, silver is not diffused in the solder, and when the temperature is 290 deg.C or over, solder is molten and solder drooping or solder balls are formed resulting in disabling welding or silver is deeply diffused in the solder, then the density of silver is decreased and no effect is obtained. The silver of the lead wire 4 is diffused in the solder when the solder is molten by selecting the heat temperature to be 200-290 deg.C and the silver of the electrode section 3 diffused into the solder is suppressed, then the exfoliation and loss of the silver of the electrode section 3 is prevented and the reduction in the adhesion strength between the lead wire 4 and the crystal 1 is prevented.

Title: Plasma treatment method
Inventor: KAWASHIMA SADAMI
IPC: H01L21/3065
Filed: 1984-07-09
Abstract: PURPOSE:To improve a yield of manufacture by omission of process by effecting a plasma treatment with using a carrier-to-carrier type crystal carrier. CONSTITUTION:Transfer of an Si wafer (it is contained in a carrier-to-cattier type Teflon carrier) of after etching of an SiO2 film to a crystal carrier and transfer of a wafer of after ashing of a resist to the carrier for a treatment of the next process are carried out at one time and the processing steps can be saved because the crystal carrier is carrier-to-carrier type. Furthermore, there is no need of using tweezers or vacuum tweezers so that the Si wafer is not demaged and a decline in yield is not caused. Also, as the crystal carrier is never deformed, such part that intervals among the positioned Si wafers of after etching of SiO2 films become narrow is not produced. Accordingly, ashing of the resist of the positioned Si wafer is all completed by a plasma ashing treatment of the predetermined time.

IPC: G05D3/12
Filed: 1983-08-03
Abstract: PURPOSE:To give the stable servo control to the seeking action speed of a movable head of a magnetic disk by composing a speed signal after a harmful mechanical vibration component is satisfactorily attenuated by means of a secondary LPF. CONSTITUTION:The speed detection signal of a disk movable head obtained by a head movable part 102 and a speed detecting circuit 103 is mixed with the output of a gain matching element 6 obtained on the basis of the detection current of a servo current detecting circuit 104 through a mixer 8. Then a high frequency component is deleted by the secondary LPF3 together with a harmful mechanical vibration component. The speed signal having a low S/N and passing through the LPF3 is mixed with a servo current detection signal passed through a gain matching element 7 and the secondary BPF4 through a mixer 9. As a result, a speed signal containing no harmful mechanical vibration component is composed with a good S/N. Thus it is possible to give the stable servo control to the seeking action speed of a movable head of a magnetic disk.
