Title: Contact position detecting device and machine tool employing said device
Inventor: MINAMINO IKUO
IPC: F16C32/04
Filed: 1988-03-30
Abstract: PURPOSE:To facilitate provision of a machining size, e.g. a grinding amount, based on a contact position, by providing a contact means which detects contact between a tool at the tip of a rotor shaft pivotally supported to a magnetic bearing and a work or other object, e.g. a dresser, from the change in position or the change in an exciting current of the magnetic bearing. CONSTITUTION:When a grinding starting button is pressed and a grinding work is started, a signal is received from a table and support bed drive circuit 23 through a D/A converter 24 by means of a control part 18 to rapidly run a servo motor 4, and a grinding stone (a) at the tip of a rotor shaft 2 pivotally supported by a magnetic bearing approaches a work (b). When the grinding stone (a) is brought into contact with the work (b), the rotor shaft 2 is moved to the position sensor 14 side. The movement of the rotor shaft increases the detecting current of the position sensor 14, and a point of time when a value equivalent to the increase exceeds a threshold preset by a setter 19 is detected as a contact position between the grinding stone (a) and the work (b). Contact occasioned by movement in a direction extending at right angles with the direction of the axis of the grinding stone (a) is detected by sensors 11 and 12.

Abstract: PURPOSE:To shorten turn-on time by forming a gate electrode in an approximate H-shaped form which is arranged at the center of an emitter layer approximately symmetrical. CONSTITUTION:PNPN4 layers consisting of the P emitter layer, an N base layer, a P base layer 4 and the N emitter layer 5 are laminated in a discoid Si wafer. A large number of short circuit holes 11, which penetrate some parts of the layer 5 and expose the layer 4, are formed, and the layer 4 is short-circuited with the layer 5 by a cathode electrode 8 through the short circuit holes 11. There exists an auxiliary thyristor at the center section of the wafer, the gate electrode surrounds the auxiliary thyristor in a ringed shape at the center section of the wafer, and arms extend in the approximately symmetrical H-shaped form from the center of the Si wafer while being connected to the ring. Accordingly, distances up to each point of the layer 5 from the electrode 10 shorten, and the presence of the short circuit holes 11 hardly function as obstacles in regard to an extent of currents. Thus, turn-on time is shortened.
