Abstract: PURPOSE:To produce a work free from dispersion in hardened quality by conveying a work, having a shaft part and a grooved part to be hardened, to a hardening stage, hardening the grooved part in the lower part of a conveyance line, and then hardening the shaft part in the upper part of the conveyance line. CONSTITUTION:A work W of constant velocity joint member, requiring hardening for a shaft part 2 and a grooved part 3, is conveyed to a hardening stage and is then centered and lowered to a grooved part heating position. The lowered work W is turned by means of a lower part center mechanism 17, and the grooved part 3 is heated by a heating coil 7 for hardening the groove part and then cooled by a peripheral jacket 9 for cooling the grooved part. After cooling is completed, the work W is raised to a shaft part heating position, and the shaft part 2 is heated by a heating coil 8 for hardening the shaft part and then, without delay, the lowering of the work W is started, and simultaneously, cooling for the shaft part 2 is also started by means of a jacket 10 for cooling the shaft part. When the work W is lowered to the position of a conveyance line L, the work W is turned until the cooling for the shaft part 2 is completed. When cooling is completed, turning is stopped and centering is released.

Abstract: PURPOSE:To enable the titled circuit to lower the variation of an output level by making the load element of a differential invertor circuit into constitution that one or plural pieces of DMESFET load, the gate drain electrode of which is short circuited, are connected. CONSTITUTION:Normally-on type Schottky junction field effect transistors (DMESFET) 104, 105 are the load DMESFETs to connect respective date electrode to the gate drain electrode, i.e., VDD. When the threshold voltage VT of the DMESFETs 101-103 varies, the threshold voltage of the load DMESFETs 104, 105 varies as well, and a circuit current IDSS varies, but the current-voltage characteristics of the load DMESFETs 104, 105 vary as well. Thus, because the output L level variation of the differential invertor circuit is small against the threshold voltage variation of the DMESFET, caused by a manufacturing dispersion, a circuit working margin is improved, and a manufacturing yield is improved.
