Title: Origin return method in numerical controller
Inventor: TANIKOSHI KEIJI
IPC: G05B19/18
Filed: 1986-02-18
Abstract: PURPOSE:To prevent a movable member from colliding to a mechanical limit and to satisfactorily return to an origin by driving a drive mechanism so that the movable member can be displaced to approach to a limit sensor at the time of switching the operation to an origin return mode. CONSTITUTION:After a power source is turned on, the movable member 2 is automatically returned to the mechanical origin by a command signal from a control circuit 12. An origin sensor 7 is discriminated in a sensitive state or not. If so, that is, the movable member 2 is in an origin vicinity area B, the drive mechanism is driven and displaced counterclockwise at a low speed until an encoder 11 outputs a unit drive signal, and inverted in response to the output of the unit drive signal. Then the movable member 2 is moved clockwise at a low speed, and a servo motor 1 is stopped in response to the output of the first unit drive signal from the encoder 11 after the origin sensor 7 is switched in an insensitive state. With the stoppage as a mechanical origin the origin return processing is terminated.

Filed: 1990-02-15
Abstract: PURPOSE: To make an oscillation frequency relatively independent of a supply voltage by using a reference voltage independent of the supply voltage in the gate bias of an n-channel transistor TR of each pair of CMOS TRs. CONSTITUTION: Plural stages each of which consists of a pair of CMOS FETs 26 and 28 are connected in a form of a ring, and each pair of FETs are connected in series between a power source VCC and the ground. Common terminals of the pair of FETs are connected to the gate of a p-FET 26 of a pair of FETs in the next stage. A fixed reference voltage VREF is applied to the gate of the n-FET 28 of each pair of FETs. A capacitive means 30 grounds the output of each pair of FETs. When a voltage extended over the capacity 30 in the preceding state is discharged through the n-FET 26, conduction of the p-FET 28 is started. Then, the voltage VREF applied to the gate of the n-FET 26 makes discharging of the capacitor 30 independent of VCC.

IPC: F02P7/02
Filed: 1981-03-13
Abstract: PURPOSE:To make durable a distributor comprising a rotor electrode and peripheral electrodes to which the rotor electrode is opposed across a minute gap and to reduce electromagnetic wave noises, by coating the spark discharge surface of the distributor with a silicone substance and exposing a part of the material of the spark discharge surface. CONSTITUTION:Among the top 16, bottom 17 and discharge section 12 of a rotor electrode 3, at least the discharge section is coated with a liquid silicone substance 13 such as silicone varnish. After the substance 13 is fixed by baking, at least one punched part 15 is provided on the discharge section 12 by a press or the like so that the metal of the rotor electrode 3 is exposed at 14. Since the rotor electrode 3 has such double structure and its inner material is exposed, a residual charge effect is produced by the silicone substance 13 without causing intermittent discharge, to reduce electromagnetic wave noises. Because the silicone substance 13 is baked after being applied, it does not flay away during the rotation of the rotor 5. According to this constitution, the durability of the rotor electrode 3 is heightened.
