IPC: H04N19/436
Filed: 1994-06-22
Abstract: PURPOSE: To keep the entire storage capacity of buffer memories as small as possible by using the N pieces of the buffer memories, provided with a storage amount smaller than a maximum storage device NC on the N pieces of parallel routes. CONSTITUTION: A demultiplexing circuit 10 provided with a single-input terminal 11 and the N pieces of output terminals 12A-12N receives encoded signals through the terminal 11 and outputs the encoded signals through the output terminals to the N pieces of parallel circuits 30A-30N. The N pieces of the routes 30A-30N perform decoding. The output signals are multiplexed by a multiplexing circuit 40, form a single data stream for indicating original video signals and are displayed. The storage capacity of the respective buffer memories is kept smaller than the N.C by an additional buffer memory circuit 20, and thus the overall storage capacity of the N pieces of the buffer memories becomes far smaller than N<2> .C.

Title: File excellent in transparency and slipperiness
Inventor: KANAI TOKUTARO
IPC: C08J5/18
Filed: 1991-05-16
Abstract: PURPOSE:To impart slipperiness (and antifog properties when used in agriculture) and long-term persistence of the slipperiness (and antifog properties) to a vinyl chloride resin film for general and agricultural use without detriment to the transparency of the film. CONSTITUTION:Acrylic resin particles are incorporated into a vinyl chloride resin film, or at least one side of the film is covered with a layer of the particles. The particles incorporated into the film protrude out of the film surface or the surface of the layer of them, giving a roughened and slippery surface. The particles, having a refractive index close to that of the vinyl chloride resin, do not adversely affect the transparency of the film, and, when the particles are spherical, diffused reflection is prevented, preventing the transparency from being lowered.

Filed: 1983-08-01
Abstract: PURPOSE:To increase the contacting area of a lead with a bump by forming the bump for one lead of a plurality of small bumps, thereby reducing the area of a recess part of the central portion of the bump at the plating time. CONSTITUTION:A photoresist 16 having approx. 40mum of pattern width is formed, and with the photoresist as a mask gold is plated to form two small bumps 7a, 7b. Since the width of the bump is approx. 40mum, a recess which occurs without approx. 20mum from the periphery of the bump at the plating time is regarded as almost non in a prindiple. Accordingly, a recess is not formed at the center of the bump. Thus, the bonding area of the lead of a lead frame with the bump after bonding the inner lead can be increased.

Title: Manufacture of self-aligning high performance lateral operation silicon control rectfier and static ram
Inventor: OSUMAN AASETSUDO AKUKASU
IPC: H01L21/822
Filed: 1988-06-10
Abstract: PURPOSE: To increase integration density, and reduce the base-collector capacity, and further, reduce the parasitic resistance, by making the rectifier into such a structure, that the width of the base region of a lateral NPN device is drastically reduced and the volume of the region of the storage charge under the base is reduced. CONSTITUTION: A transistor T2 is a lateral PNP device, a transistor T5 is a lateral NPN device, a transistor T3 is a vertical NPN transistor, transistors T1 and T4 are parasitic board PNP transistors, and the width 47 of the lateral NPN base is drastically narrow, since it is self-aligned. A small-sized structure is made and the width of the NPN base is greatly reduced by an emitter and the right end of a base region being self-aligned with the left end of an injector. Because the storage charge under the lateral NPN base decides the switching time, the width is made as narrow as possible.

Title: Descaler for steel material
Inventor: FUKUZUKA TOSHIO
IPC: B21B45/00
Filed: 1977-11-24
Abstract: PURPOSE:To remove easily strongly adhered primary scale by a high pressure water jet descaler by suppressing as much as possible the cooling of steel by providing a heat insulating cover, a heater, etc., on the path of steel from the heating furnace for steel to descaler in the rolling of steel by a hot rolling mill. CONSTITUTION:When the steel 8 is heated at the heating furnace 3 and then rolled by the hot rolling mill 1, the primary scale on the surface is removed by the descaler using a high pressure water jet in advance. However, the primary scale adhered to such steels as aluminium-killed steel, silicon-killed steel, etc., is difficult to remove. Since the removing rate of scale by the descaler 4 is better the higher the temperature of steel, the heater 9, e.g., burner, etc., is placed between the heating furnace 3 and the descaler 4, or the temperature of steel is kept by the heat insulating cover 5 to keep its surface temperature at more than 1000 to 1050 deg.C and then the steel is sent to the descaler 4. Thus, the primary scale on the killed steels can be easily removed.
