Title: Spindle motor and disc drive employing it
Inventor: SAITOU FUMIAKI
IPC: H02K21/22
Filed: 1998-11-13
Abstract: PROBLEM TO BE SOLVED: To limit tilting of a drive pin at the time of chucking and to make smooth vertical motion of the drive pin by providing a side wall where a linear part rising in the axial direction and a following curve part are formed continuously in an oval or arcuate hole for passing the drive pin made in a rotor case. SOLUTION: When a spindle 25 is inserted into the central hole 54 of a disc 56 at the time of chucking and a rotor case is turned, top face of a drive pin 28 turns while sliding on the lower surface of a disc 56. The drive pin 28 is reset upward by the reaction of a leaf spring 30 at a position aligned with the drive hole 55 of the disc 56 and fitted in the drive hole 55. A side wall 29 where a curved part and a linear part are formed continuously is provided in an oval or arcuate hole 53 for passing the drive pin made in a rotor case. According to the structure, the air gap between the drive pin 28 and the side wall 29 is reduced by enhancing the machining accuracy of the side wall 29 and the tilting angle of the drive pin 28 is decreased. Furthermore, vertical motion is made smooth and chuck miss can be prevented.

Title: Gas insulated switch
Inventor: SHIRAISHI MASAZUMI
IPC: H02B13/02
Filed: 1990-11-28
Abstract: PURPOSE:To remove minute gaps and materialize a compact insulating bushing excellent in voltage resistance property by filling up the minute gap, which occurs between the insulating bushing and the insulating bushing mounting base, with liquid-form insulator, and then hardening it. CONSTITUTION:Addition-reaction hardenable liquid-insulator 15 is filled up on the surface of an insulating bushing 11, which fronts the opening of an insulating bushing mounting plate 8D or 8E. Since the addition-reaction hardenable liquid-insulator 15 is of low viscosity before hardening, silicon gel is filled in the minute gap generated between the insulating bushing and the mounting plate. By the minute gap being filled up with insulator, the electric field concentration of the minute gap does not occur, and voltage resistance property improves. Hereby, the voltage resistance property improves more than ever, a compact insulating bushing can be offered, in its turn a compact SF6 gas insulated switch can be materialized.
