IPC: H01L27/02
Filed: 1995-02-07
Abstract: PURPOSE: To provide a semiconductor device of a simple wiring structure wherein current amplification factor of an IIL transistor is high. CONSTITUTION: Relating to a semiconductor device containing an IIL transistor, an n-type diffusion layer 9, acting as a collector area, is electrically connected to a contact part of an aluminum wiring 10, with a polysilicon cap 11 so formed as to cover the n-type diffusion layer 9 in between. The size of a contact hole 8 for the collector area or the contact part of the aluminum wiring 10 is made smaller than the collector area, so that, without extending interval of the collector area. the aluminum wiring can be assigned between the collector areas. Thus, Sc/Sb of the IIL transistor can be larger, and current amplification factor βeff of the IIL transistor is raised. The aluminum wiring 10 does not need to be of multilayer structure, so, wiring structure is simplified.

Title: Production of application tape
Inventor: SAITO MASAO
IPC: C09J7/02
Filed: 1994-02-16
Abstract: PURPOSE:To provide an application tape which causes no change in adhesive strength of a pressure-sensitive adhesive with the lapse of time and is excellent in anchoring of the pressure-sensitive adhesive to a paper substrate by directly coating a paper substrate with an acrylic pressure-sensitive adhesive, drying the coating, and then conducting humidity conditioning. CONSTITUTION:A paper substrate is directly coated with an acrylic pressure-sensitive adhesive, and the coating is dried and then subjected to humidity conditioning, thereby preparing an application tape. Alternatively, an acrylic pressure-sensitive adhesive layer formed on the surface of a processing paper may be transferred onto a paper substrate impregnated with an acrylic emulsion to prepare an application tape. Since the paper substrate is impregnated with an acrylic emulsion, the paper substrate has an improved affinity for the acrylic pressure-sensitive adhesive, contributing to a significant improvement in adhesive strength. Therefore, even when the acrylic pressure- sensitive adhesive is applied by transfer, no adhesive transfer to an adherend occurs, enabling the preparation of an application tape having excellent die cuttability. Further, even when no humidity conditioning is carried out, neither curl nor cockle occurs, offering a good production efficiency. Furthermore, neither change in adhesive strength nor discoloration and fading with the lapse of time occurs.

Title: Rack device for refrigerator
Inventor: OOSHIMA ATSUHIRO
IPC: F25D25/04
Filed: 1990-01-30
Abstract: PURPOSE:To prevent spur gears from levitating from a rack and eliminate the danger of dropping of the rack by a method wherein the spar gears at both left and right ends are rotated simultaneously on the rack by a driving device, rotating a gear shaft or the spur gears, to permit the up-and-down movement of the rack and a frame while retaining them horizontally while a projection, proximated to the gear shaft, is formed at the inside of the section of a rear frame. CONSTITUTION:Spur gears at both left and right ends are rotated simultaneously on a rack 14b by a driving device 6, rotating a gear shaft 4 or the spur gears 5, whereby a rack 1 and a frame 2 can be moved up-and-down while keeping them horizontally. When much food is put on the rack, a load is transmitted from the rack 1 to the frame 2, the gear shaft 4 and the spur gears 5. Accordingly, the gear shaft 4 is deflected and the spur gears 5 are levitated from the rack. The deflection of the gear shaft 4 is pushed by a projection 2d formed on the rear frame 2c whereby the levitation of the spur gears from the rack is suppressed. On the other hand, an interval between the left and right frames 2 can be set arbitrarily by cutting the rear frame by a proper size. Accordingly, the left and right frames 2 can be arranged easily in a different refrigerator.
