Title: Axial line bending method for work and its device
Inventor: KITSUKAWA MOTOHIKO
IPC: B21D7/08
Filed: 1989-12-11
Abstract: PURPOSE:To reduce the frictional resistance and to prevent the damaging of work or the abrasion of supporting device by feeding the long size work, inserting it through the supporting device, holding with the bending device and applying the vibration to the contacting part of the work and supporting device in the state of shifting the bending device. CONSTITUTION:The long size work 2 is fed in the axial direction with the driving device 11, this work 2 is inserted into the inserting hole of the supporting device 3, and held with the bending device 5. And in the state of shifting the bending device 5 against the axial line, the contact part of the supporting device 3 and the work is subjected to vibration with the vibration applying device 13 and the work 2 is bent. In this time, the frictional resistance on the sliding surface of the supporting device 3 is reduced and the inserting through of the work is easily executed. The vibration is applied in the sliding direction in order to promote the relative reciprocating motion on the sliding surface. Further, if the ultra-sonic vibration is applied, the reduction of the sliding resistance becomes remarkable.

Title: Pulse laser device
Inventor: OKAMURA KATSUYA
IPC: H02M9/04
Filed: 1990-11-27
Abstract: PURPOSE:To see that the oscillatory current flowing in the switch part does not flow even in the case that the impedance matching between a power source circuit and a laser discharge part is not taken by connecting the series circuit of a diode and a resistor in parallel with the capacitor at the preceding stage of a magnetic pulse compressing circuit. CONSTITUTION:A peaking capacitor CP is reversely charged due to the unconformity between power source impedance and discharge impedance. Even when a capacitor C2 is charged in the middle by a semiconductor switch SW being turned on, since the polarity of a diode 12 is the one of holding the charge voltage of the capacity C2, there is no influence at all. Moreover, once the peaking capacitor Cp is reversely charge, this time the peaking capacitor Cp discharges electricity through a resistor 11, a diode 12, and a saturable reactor SL. At this time, when the saturable reactor SL saturates, impedance is matched between the circuit impedance being determined by the inductance and the peaking capacitor and the resistor 11, so discharge current attenuates quickly.

Abstract: PROBLEM TO BE SOLVED: To normally supply a normal dynamic focusing voltage by correcting a focusing voltage deviation in the center of a cathode-ray tube owing to the AC component difference of the dynamic focusing voltage to be impressed by means of the change-over of a DC voltage component in an impression focus voltage at the time of receiving a signal being different in a horizontal scanning frequency or a video signal period, etc. SOLUTION: When a signal system is different, the focusing voltage is impressed during a video signal period by the constant change-over setting of an LC resonance circuit which is constituted of a transducer 7, a resistor 8, a coil 9, a capacitor 10 and a transistor 11, a dynamic focusing waveform is made to be equal to a cathode-ray tube effective screen waveform but, even in this case, the waveforms of a whole period are different and AC zero-points are different. The actual impression voltage to a cathode-ray tube focusing terminal is the summed voltage of the DC voltage from the focus adjusting volume 3 center top and the AC voltage of the capacitor 6, the focus deviation in the center of the cathode-ray tube occurring when the signal system is different is avoided by permitting the resistor 4 to be connected or short-circuited and receiver image quality is improved.

According to the aforesaid construction, the equipotential lines in the vicinity of the tip part A of a fixed main contact 15 is off the tip part A and the aforesaid gap becomes large, thereby alleviating electric field concentration. Also, electric field concentration is similarly alleviated at the tip part B of a fixed arcing contact 25. Consequently, potential distribution between electrodes becomes uniform.

IPC: H01L21/22
Filed: 1988-12-21
Abstract: PURPOSE:To make it possible to perform accurate heat treatment by directly measuring the temperature of a wafer or the vicinity of the wafer with non- contact type thermometer, and controlling the temperature of a heat treating apparatus.
