Title: Laser beam marking device
Inventor: OSHIMA MICHIHIRO
IPC: B23K26/08
Filed: 1993-04-08
Abstract: PURPOSE:To provide a laser beam marking device for easily executing the marking with the laser beam at high speed as the same degree as the marking on a flat plate. CONSTITUTION:A pulse motor is rotated in a straight line stage 45 to drive and rotate the screw shaft, and a supporting table 25 screw-connected with the screw shaft is advanced. A holder 22 supported so as to be rotatable to a supporting wall body 24 and a member 21 to be worked, fitted to the holder 22 are advanced in the same direction as the supporting table 25. At this time, as the holder 22 is wound in one round with the wire 31, the member 21 to be worked, fitted to the holder 22 is rotatively moved while moving to the straight line. The member 21 to be worked, giving the rotative movement together with the straight line movement can be regarded as one flat plate in the case of observing from a laser head 60. Therefore, a program for executing the marking on the flat plate can be used and the marking can easily be executed to the member to be worked with the laser beam at the high speed as the same degree as the marking on the flat plate.

IPC: F25B41/06
Filed: 1990-03-29
Abstract: PURPOSE:To keep a cooling capability and provided a positive lubrication of a compressor by a method wherein a diaphragm is flexed in response to a pressure difference between a refrigerant chamber and a thermo-sensitive chamber, a valve disc is moved through a plunger and a degree of opening of an expansion orifice is adjusted. CONSTITUTION:A plunger 29 is always biased upwardly by a compression coil spring 11 through a spring seat 9, a valve disc 8 and an operating rod 31. Accordingly, a position of the valve disc 8 in respect to the valve seat 7 (a degree of opening of an expansion orifice) is kept at a position where a biasing force of the compression coil spring 11, a refrigerant pressure in a refrigerant chamber 25 and a gas pressure in a thermo-sensitive chamber 24 are balanced to each other. An amount of refrigerant supplied to an evaporator 18 is adjusted in response to a degree of opening of an expansion orifice 6. In turn, since a coefficient of thermal expansion of refrigerant circulating in a freezing cycle and a coefficient of thermal expansion of inert gas enclosed in the thermo-sensitive chamber 24 are different from each other, when a thermal load of the evaporator 18 is low, a discharging amount of refrigerant in a variable volume compressor 15 is less, the refrigerant in liquid phase is returned back to the compressor 15 and then a mechanism of the compressor 15 is lubricated by lubricant oil contained in the refrigerant.

Title: Agc circuit
Inventor: YAMASHITA NORIYUKI
IPC: H04N5/53
Filed: 1986-04-10
Abstract: PURPOSE:To prolong the attach time even when the capacitance of a charge/ discahrge capacitor is small by applying charge/discharge of the AGC voltage at a part of the vertical blanking period. CONSTITUTION:When an AGC error voltage Ve rises and the relation of Ve>Vc is obtained. The collector current of a transistor (TR) Q1 is larger than a con stant current IO corresponding to a difference voltage Vd= ¦Ve-Vc¦ and the collector current of a TR Q4 is larger than the constant current IO. Since the collector current of the TR Q2 is smaller than the constant current IO, the current corresponding to the difference voltage Vd is conducted from the collec tor of the TRQ4 to the capacitor C1, which is charged up. The voltage Vc rises through the charging and when the relation of Ve=Vc is obtained, the charging to the capacitor C1 is stopped. Since the charging is executed only at Pv='L', the terminal voltage Vc of the capacitor C1 rises little by little at every vertical blanking period. Since the AGC is applied by the voltage Vc, the attack time is prolonged.

IPC: G11B7/2405
Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To eliminate the occurrence of a defect of application of a resin due to rupturing of air bubble and scattering and to make the quality higher and the productivity better by switching the inside of a vacuum chamber from a vacuum to the atmospheric pressure when the generation of the air bubbles in the resin is detected in a stage for bonding the resin onto a substrate. SOLUTION: The end face of a substrate 101 coated with a resin 104 is clamped by a substrate chuck 102 in a vacuum chamber 108 and the evacuation of the vacuum chamber 108 is started. Air bubble detecting sensors 105a and 105b arranged in prescribed positions monitor the resin surface at all times. When the sensors detect the bulging by the air bubble 106, the sensors top the vacuum and open a leak valve 109 to restore the atmosphere pressure in the vacuum chamber 108. When the air bubble does not exist any more, the vacuum evacuation is started again. This operation is repressively executed until the vacuum degree attains a set value. The operation to switch the inside of the chamber to the vacuum and the atmosphere pressure is carried out several times in the manner described above, thereby, the application stage for coating can be processed without the rupture of large air bubbles.

Abstract: PURPOSE:To conduct quenching accurately into a free shape by irradiating laser light intermittently at a worked matter surface, quenching a necessary portion only, and then, cutting unquenched surface containing portions only, and grinding the quenched portion. CONSTITUTION:A middle material 1a is scraped out of a round stick material with a finishing stock left at a cylindrical portion 2 outer diameter, and quenching is conducted by irradiating laser light scanned in a rotary axis direction from a laser head 20 while a chuck 13 is being rotated. At this time, a laser oscillator is conducted with ON/OFF control so that cylindrical surface portions which are to become a groove 3 and a key 4, mat not by quneched. Afterwards, unquenched portions, that is, the groove 3 and key 4 portions are removed by means of end mill cutting working, and then, the outer periphery of the cylindrical portion 2 is ground by means of a cylindrical grinder. As a result, there is no need of conducting the grinding work of groove 3 and the bottom surface of key groove 4 and a side wall 7, so component working including a qunching process can be conducted extremely efficiently.
