Abstract: PURPOSE:To enable elimination of a space area formed in a dehydration shaft as a specified installation space by providing a one-way clutch which is mounted in a space between a washing and a dehydrating drum to enable intercoupling of the two drums. CONSTITUTION:Though a band brake 33 brakes a dehydration shaft 31 during washing operation, it has one-sided effectiveness, in which it is effective only to one-way rotation, in terms of a mechanism. Thereby, a one-way clutch 40 is mounted between washing and dehydrating drums 2 and 3 so that rotation in an opposite direction thereto is braked. The one-way clutch 40 is formed on the under surface side of the bottom part of the washing drum 2 such that an annular boss part 41 is protruded upward.

Title: Semiconductor device
Inventor: HIRASHIMA TOSHINORI
IPC: H01L21/60
Filed: 1999-08-25
Abstract: PROBLEM TO BE SOLVED: To make a semiconductor device thin, improve the radiation property of the semiconductor device, drop the on-resistance and operate the device at a high speed by installing an insulating sheet, covering the first main face of a semiconductor chip in an area except for a region where a plurality of projecting electrodes are arranged. SOLUTION: An insulating sheet 9 is laid between the element-forming face of a semiconductor chip 10 and the first parts 2A and 3A of a lead 2 and a lead 3. Projecting electrodes are installed between the electrode of the semiconductor chip 10 and the first parts 2A and 3A of the lead 2 and the lead 3, and they are thermally compression-bonded. Thus, a resin path by resin forming becomes unnecessary, and the overall thickness of a package becomes small, by the amount corresponding to the thickness of the resin path. Since the upper faces of the first patterns 2A and 3A and the second parts 2B and 3B as a whole of the leads 2 and 3 are exposed from the insulating sheet 9, radiation property for discharging heat generated from the semiconductor chip 10 outside becomes high.  Thus, the semiconductor device can be made thin, radiation property can be improved, and on-resistance can be dropped.

Abstract: PURPOSE: To completely burn out organic binder resin with almost no oxidation of copper paste metal without decomposing of a ceramic layer by sintering a laminated non-sintered green complex, containing a copper paste metal by microwaves. CONSTITUTION: This composite material containing thermoplastic organic binder, wherein particles selected from a group comprising glass particles and the mixture of the glass particles and crystalline particles are dispersed, is used, and a green sheet, which forms a patterned metallic layer and has the sintering temperature less than the melting point of a conductor, is formed.

Then, the overlapped and laminated sheets are laminated together, and the laminated body is heated by microwaves to a burn-out temperature. Thus, a binder in the green sheet is decomposed and removed. Thereafter, the laminated body is sintered, and the desired ceramic composite structure is obtained.
