IPC: B21B15/00
Filed: 1992-01-30
Abstract: PURPOSE:To enable restraining breadthwise variation small at the tip and rear end in the rolling of the ensuing stage by edging a slab for widening the tip part and rear end part so as to provide plural stair-like stepped parts. CONSTITUTION:A slab 2 is successively fed between press tools and the slab width of the slab 2 is rolled down with the inclined part of the press tool. When the slab is passed between the tools by a prescribed length, a 1st stepped part 2a is formed by narrowing the rolling-down width to a width corresponding to a 2nd width widening amount. When the slab is further passed through the tools, the 2nd stepped part 2b is formed. While the rolling-down width is held in a normal width as it is, edging is continued. In this way, widened area having the stepped parts 2a, 2b of two steps is formed at the tip of the slab 2. The slab 2 is further fed between the tools, the 1st stepped part 2c on the side of the rear end part is formed and then, the 2nd stepped part 2d in the rear end part is formed by widening the rolling-down width by one corresponding to the 2nd width widening amount in the rear end part when the prescribed amount of the slab 2 is passed.

Filed: 1992-01-30
Abstract: PURPOSE:To improve EMI characteristic by constituting LPF with the capacitor of a filter circuit and the inductor of a boosting converter part so as to reduce a switching frequency noise. CONSTITUTION:The boosting converter part 22 inputs AC rectified by a rectification circuit DB through an inductor L3, turns it on/off with a switching device Q and charges it to a capacitor C3 through a diode D. A power factor improvement control circuit 24 turns a switching element Q on/off with high switching frequency to stabilize the output of the boosting converter part 22. LPF is constituted of a capacitor C4 connected between a loading line and a feed-back line, which are communicated with the rectification circuit DB and the boosting converter 22 and the inductor L3 of the boosting converter part 22 so that the switching frequency noise is reduced. Thus, the EMI characteristic is improved.

Filed: 1978-02-14
Abstract: PURPOSE:To prevent scattering of magnetic fluid by providing non-magnetic members on the opposite sides of magnetic poles in such a manner that they face a movable shaft. CONSTITUTION:Cylindrical members 7 and 8 of a non-magnetic material are mounted on the sides of magnetic poles 2 and 3 such that they face a shaft 1, and they are not penetrated by the magnetic flux 6.
