IPC: C23F13/20
Filed: 1994-01-20
Abstract: PURPOSE:To provide a potential automatic control type electric protection method having a system in which protection current from an anode of galvanic anode method is controlled so that the potential of a body to be protected measured by a reference electrode may be normally maintained at a fixed set potential in cathode protection of galvanic anode method and to provide a simple controlled potential automatic control device for it. CONSTITUTION:An anode of galvanic anode method 2 and a body to be protected are connected to a collector and a emitter of a bipolar type power transistor 5 or a drain and a source of an electric field effect type power transistor respectively. The difference between a potential Ep of the body to be protected measured by a reference electrode and a set potential Es is amplified by a voltage amplifier 6 driven by a power source other than that for a transistor 5. By controlling a collector current or a drain current of the transistor 5 by the output of the voltage amplifier 6, the potential of the body to be protected is controlled and maintained at a set potential.

Title: System for return to origin of cnc
Inventor: BAIDA TERUO
IPC: G05D3/12
Filed: 1995-02-07
Abstract: PURPOSE: To return to an origin without using any deceleration switch or dog concerning the system for return to the origin of CNC for confirming a machine origin position at the time of machining start. CONSTITUTION: A linear scale 2 is fitted to a table 1 along the moving axis of the table 1. This linear scale 2 outputs pulse signals at fine intervals corresponding to the moving amount of the table 1 and one reference origin signal corresponding to the machine origin position at least on its one terminal side. At prescribed timing such as when a power source is turned on or a command is inputted from a console, a return-to-origin control means 3 sends the command of an operation for return to origin to a servo amplifier 4. Thus, a servo motor 5 is driven and the operation for return to the origin is performed to the axis of the table 1 or the like to be the object of return to the origin. Then, the return-to-origin-control means 3 stops the operation for return to the origin corresponding to the timing when the reference origin signal is inputted.

Filed: 1987-01-31
Abstract: PURPOSE:To reduce the operation noise by installing a band body which is laid in free slidable contact onto the peripheral surface on the pump part side of an eccentric cam and can be bent in reciprocation. CONSTITUTION:The both edge parts of a bend-shaped body 62 in a thin elastic metal belt form which is laid in free slidable contact or rolling contact on the peripheral surface on the pump 10 part side of an eccentric cam 49 and can be bent in reciprocation are fixed onto the inner surface of a center space part 42.

IPC: H04L7/027
Filed: 1985-02-05
Abstract: PURPOSE:To improve the transmission characteristic and to attain long ranged transmission distance by using the level of a received waveform so as to change the phase of a data extracting clock. CONSTITUTION:A bipolar pulse signal from an electronic exchange side passes through a transformer 1, enters a rectifier circuit 2 and becomes a unipolar form pulse signal. The unipolar form pulse signal enters a positive input of a comparator 5 and a peak value/threshold value setting circuit 3. A threshold value 2 of the peak value/threshold value setting circuit is set usually to a half of a peak value 1 and the set value is impressed to an inverting input of the comparator 5. A pulse waveform shown in figure (b) appears at an output of the comparator 5 and the shaped pulse signal enters a flip-flop circuit 6 and a PLL circuit 7. The clock extracted in the PLL circuit 7 enters a phase adjusting circuit 8, and an output signal of a comparator 4 enters the control input of the phase adjusting circuit 8. Thus, when the transmission range is short, a signal of level '1' is fed to the control input of the phase adjusting circuit 8 and when the transmission range is long, a signal of level '0' is fed to the control input of the phase adjusting circuit 8 so as to control the phase.
