IPC: H03M1/10
Filed: 1992-04-16
Abstract: PURPOSE:To reduce a voltage adjustment time for a deviation in an offset voltage by adjusting the offset voltage with a 2nd offset adjustment voltage having a larger step width than a step width of a 1st offset adjustment voltage. CONSTITUTION:A logic means 5 outputs an H level logic signal when OR of the high-order prescribed number of bits of m-bit digital signal except the MSB outputted from an A/D converter 2 is at an H level and outputs an L level logic signal when the OR is at an L level. A D/A converter means 6 outputs a 2nd offset adjustment voltage having a larger step width than a step width of a 1st offset adjustment voltage when the D/A converter means 6 receives an H level logic signal from the means 5 and a positive or negative overflow signal from an U/D counter 3. When the logic signal reaches an L level, the means 6 outputs the 1st offset adjustment voltage. A switch section 7 connects the input side of the filter 1 to ground while the logic signal applied thereto is at an H level. As a result, when an offset voltage is deviated largely in the initial state, the offset voltage adjustment time is reduced.

Title: Induction hardening method of thin-walled ring
Inventor: ITOU HIROSHI
IPC: C21D1/10
Filed: 1982-06-05
Abstract: PURPOSE:To prevent the plastic deformation and the deviation in the axial center of revolution owing to expansion during hardening and to obtain a desired hardened layer and dimensional accuracy, by supporting and restraining the circumferential surface of a thin-walled ring elastically in the stage of subjecting said ring to induction hardening. CONSTITUTION:The circumferential surface of a thin-walled ring A is supported elastically by plural elastic members such as leaf spring 13 or the like installed on a rotary support ring 11. The ring 11 is rotated in this state and while the ring A is rotated, the ring is heated with an induction heating coil B opposed to the circumferential surface thereof to apply high-frequency hardening thereon. Even if the ring A expands in the diametral direction, the springs 13 deform elastically following up to the expansion, and the elastic deformation of the circumferential surface of the ring A is prevented by supporting the restraining with the springs 13. The dimensional shrinkage after cooling is thus prevented. Since the springs 13 support the ring A in contact with the equally divided positions in the circumferential direction thereof, the stable depth and hardness of the hardened layer are obtained without deviation in the axial center.
