Title: Vibration control method and device of wire electrode for wire cut spark discharge machine
Inventor: MORI NAOTAKE
IPC: B23H7/10
Filed: 1986-03-20
Abstract: PURPOSE:To restrict sufficiently a lateral vibration of a wire electrode owing to the discharge reaction during the processing, and improve the processing accuracy, by furnishing an electromagnetic exciting unit, an oscillator, a pulley, a brake roller, and the like, and converting a tension imposed to the wire electrode periodically. CONSTITUTION:When a vibration of an electromagnetic exciting unit 1 is delivered to an oscillator 2, a pulley 3 is vibrated up and down. Since the wire passes through the pulley 3 after a specific tension is given to the wire by a brake roller 21, a new vibrating tension is given to the wire, and the tension of the wire varies vibrantly as a whole centering around the tension given by the brake roller 21. Therefore, in the wire oscillating system between an upper and a lower dices 26 and 26, the tension as the parameter of the system is converted to control the lateral vibration sufficiently. Consequently, the processing accuracy such as the accuracy of straightness can be improved.

Abstract: PURPOSE:To shorten the period of a read scan by using a CCD image sensor as a charge storage type photoelectric converting element and also by taking a scan for erasing charge accumulated in the element by residual light from a light source. CONSTITUTION:Fluorescent lamp 1 is applied with a driving voltage from fluorescent-lamp lighting power source 7 for time TA. Then, the time from the start of the lighting of fluorescent lamp 1 until light emitting intensity becomes zero is denoted as TB. Next, CCD image sensor 14 is made to take a scan for reading signal charge accumulated for time TA from the point in time when the driving voltage to fluorescent lamp 1 becomes zero, thereby obtaining a color-separated picture signal. Next, a scan for reading signal charge accumulated in sensor 14 is carried out by the residual light of fluorescent lamp to discharge sensor 14 completely. Then, the picture signal obtained by this scan is inhibited from being output. From when the read scan of sensor 14 is started, switch 8 is changed over and fluorescent lamp 2 is applied with the driving voltage from electric power source 7 for the same operation.

Title: Controller for generator
Inventor: TAKAYAMA AKIRA
IPC: H02P9/04
Filed: 1988-03-18
Abstract: PURPOSE:To extend the life of a generator by reducing a set voltage in accordance with the temperature of a generator. CONSTITUTION:When the output voltage of a generator 1 rises so that a potential at a point A rises, a potential at a point P becomes high. When a potential at a point P exceeds the breakdown voltage of a Zener diode D1, a transistor Tr1 turns ON, and a transistor Tr2 turns OFF. Thus, no current flows from a battery 4 to a field coil 7, and no current develops in the generator coil 1. On the other hand, when the temperature of the generator rises due to the temperature rise around the generator and the heat generation of the generator itself, the resistance value of a thermistor 10 is increased so that the potential at the point P becomes high. Thus, the life of the generator can be extended.

Abstract: PURPOSE:To detect short-circuited and disconnected spots of a converter quickly and accurately by forming a Wheatstone bridge so as to make one arm thereof as one arm of a bridge of a converter using a strain gauge to perform an indication based on an unbalanced output. CONSTITUTION:Terminals of a converter 1 using a strain gauge are connected in the combination of A-B, B-C, C-A or D-A to form one arm of a Wheatstone bridge 3 in response to the operation of a rotary switch 2. At the same time, LEDs D1-D4 or D5-D10 are selected at a display section 7 corresponding to the combination of terminals A-B... with a switch 6 interlocking the switch 2. Short-circuiting is detected by lighting of the LEDs D1-D4 through a pnp-type transistor Tr1 responding to a negative output due to imbalance of the bridge 3 while disconnection at the gauge or the terminals is detected by lighting of the LEDs D5-D10 through an npn-type transistor Tr1 responding to the positive output. With such an arrangement, short-circuited and disconnected spots of the converter using the strain gauge are detected quickly and accurately.
