Title: Operating system for dc control power source
Inventor: OSHIMA HIROSHI
IPC: H02M7/08
Filed: 1988-12-14
Abstract: PURPOSE:To reduce the load of a flyback DC/DC converter by providing a DC control power source for a control circuit through rectification of AC power when the AC power source is sound while through a battery upon power interruption. CONSTITUTION:When an AC power source is sound, AC power is transformed 108 and rectified 109 to produce DC power which is fed through a high level priority circuit 110 to DC power source control circuits (DCCC) 107 and DCCC 115. The DCCC 107 controls the gates 111, 112 of a rectifier 102 and an inverter 103 and provides an output to a priority circuit 113. When power is interrupted, a control circuit 114 receives output from the DCCC 107 through the high level priority circuit 113 based on the output from a sensor 16, while the DCCC 107 receives battery 106 voltage from the high level priority circuit 110. By such arrangement, load of the DCCC 107 and 115 functioning as flyback DC/DC converter is reduced and the size of element is reduced.

After the above sintering or in the course of sintering, the above sintered alloy essentially containing carbon is subjected to surface decarburizing treatment at a temp. in the solid-liquid coexisting temp. range of the binding phase. In this way, the relative concentration of the binding phase in a surface layer at a depth of 10-500mum from the surface of the sintered alloy reaches a maximum at the outermost surface, and, in the part at a depth down to at least 5mum from the surface, the concentration is reduced with the approach to the innermost part and comes close to the average concentration in the inner part. The resulting surface-tempered sintered alloy has breaking resistance and wear resistance sufficient to be used as a base material for a coated sintered hard alloy.

CONSTITUTION:In a process that a process treatment to a wafer 15 is finished and the wafer 15 is delivered to a robot for transfer use, after the application of a voltage to an electrostatic chuck 1 is stopped, an ascension and descent operating rod 25 performs a descending operation by the drive of a driving part 24. At this time, a direct-acting type knock-out pin (the ejection member of a first group) 26 is ejected toward the central part of the rear of the wafer 15 and at the same time, a swing cam (the ejection member of a second group) 29 is made to swing through a joint 27 and a rotating rod 28 and is ejected toward the outer peripheral part of the rear of the wafer 15. Moreover, the wafer 15 receives an ejection force so as to peel from the chucking surface of the chuck 11 at 8 places in total of 4 places on the periphery of the central part of its rear and 4 places on the periphery of the outer peripheral part of its rear. Thereby, a local warpage is never generated in the wafer 15 and the wafer 15 is forcedly peeled from the chuck 11 against the sucking force of a residual charge as keeping an attitude identical with that at the time of suction.
