Title: Resistance welding equipment
Inventor: TAKASAKI HIROYUKI
IPC: B23K11/24
Filed: 1999-07-19
Abstract: PROBLEM TO BE SOLVED: To provide an excellent welding by preventing a large electric current at an earlier stage of a welding by connecting capacitors in parallel in a rectifier circuit connected to an AC power supply, controlling the rectifier circuit with a compensation control unit for a voltage fluctuation, and controlling a pulse-width with a fixed pulse width controlling unit. SOLUTION: When a welding starting switch 52 is closed, a rectifier circuit 54 performs a full-wave rectification of the confluence output of a three-phase AC power supply 50 and charges a capacitor 56. The charged voltage of the capacitor 56 detected by a charged voltage detection unit 64 is transmitted to a fixed pulse-width controlling unit 70. When the charged voltage reaches a prescribed value, the fixed pulse-width controlling unit 70 makes an inverter 58 begin to operate at a fixed pulse width. Thus a welding electric current flows into welding electrodes 24a and 24b and a weld starts. While the welding is carried out, when a the charged voltage of the capacitor 56 drops to an allowable value or smaller, a voltage fluctuation compensation control unit 66 immediately advances the ignition angle of an SCR in the rectifier circuit 54 to increase the charging voltage and recover the charged voltage to a prescribed constant value.

Title: Original platen for copying machine
Inventor: SUDO AKIRA
IPC: G03G15/04
Filed: 1985-09-19
Abstract: PURPOSE:To facilitate copying work by providing a cushion plate on the main body of an original platen through a compressing spring and providing a stopper to abut on transparent plates interpolating the original between them, on the main body. CONSTITUTION:The distance of the original surface to the optical system of the copying machine is executed by a transparent plate 29 positioned by a stopper 31, and the correct focusing to the original surface can be executed. The fine unevenness on the original surface due to the sticking original is absorbed by the thrust force of a comparatively soft cushion plate 27 and the occurrence of the shadow in the copying image is prevented. On the other hand, in case of the thick original, the whole surface of an original placing table surface is displaced by the elasticity of a compressing spring 25, and the focus surface can be always maintained by the stopper 31.

IPC: H03D13/00
Filed: 1985-09-19
Abstract: PURPOSE:To apply automatic correction so as not to cause a phase difference by providing a compensation multiplication circuit having the same circuit constitution and the same performance in addition to a desired multiplication circuit. CONSTITUTION:Since a high frequency signal inputted from an input terminal B and a signal inputted to an input terminal C have a different signal path, they receive a delay due to a transistor (TR) and a parasitic capacitance and their phase differ from each other. When the high frequency signal is inputted to a correction multiplication circuit 3, an error voltage between input voltage takes plate at an output of a differential amplifier 7. A current of a variable current source 402 is decreased by the error voltage. Then the gain band width fT of a TR 401 is decreased. Then the output of the 2nd phase shift circuit 4 is a phase-shifted signal. Then an output voltage of said differential amplifier 7, that is, a control voltage controls said variable current source 402 so as to zero the phase difference between the signal subjected to said phase shift and the signal inputted from other input terminal C'.
