Title: Spray casting method
Inventor: OOHASHI MICHIO
IPC: B22D23/00
Filed: 1982-09-20
Abstract: PURPOSE:To prevent oxidation during atomizing and to perform spray casting without macro segration by ejecting liquid hydrogen to the molten metal flow falling downward from a vessel for molten metal, and capturing the liquid drop which is internally melted in a casting mold. CONSTITUTION:Molten steel is charged through a vessel such as a ladle 1 or a tundish 2 to the center of a liquid dropping nozzle 3. On the other hand, the liquid hydrogen of an ultralow temp. supplied from the nozzle 3 is ejected toward charging molten steel flow 5. The molten steel flow is made into fine liquid drops here and the liquid hydrogen colliding against the molten steel evaporates simultaneously with the collision. The pulverized steel particle falls toward a casting mold 7 while dispersing slightly. The molten steel flow under falling is cooled by the liquid hydrogen and the evaporated gaseous hydrogen of a low temp so that the molten steel is captured in the semi-solidified state having partly solidified surface skin and is charged into the mold 7. A cast ingot is obtd. after cooling. Since this operation is accomplished in a casting chamber 8, the operation in a gaseous hydrogen atmosphere is possible without causing any problem that arises in oxidation.

Title: Glossy-finish belt
Inventor: IBUCHI YOSHIAKI
IPC: B29D29/00
Filed: 1988-06-29
Abstract: PURPOSE:To make handling simple and to eliminate the lowering of image quality and the generation of abnormal sound by applying fluororubber and/or a specific fluorinated polymer to a base sheet composed of polyimide resin. CONSTITUTION:A glossy-finish belt 53 is constituted of a three-layer structure consisting of a polyimide film 53a, a primer 53b and a tetrafluoroethylene/ hexafluoropropylene copolymer (FCL) 53c. For example, the primer 53b composed of an epoxy adhesive is applied to the polyimide film 53a and the FCL 53c is applied thereto two times to perform baking and vulcanization. The releasability of the polyimide resin is enhanced by fluororubber and the FLC and the generation of unpleasant sound such as 'crump' at the time of the separation of paper is prevented. Since the heat resistance of the polyimide resin is extremely good, wavy strain is not generated by long-term use and handling is also simple.

Title: Image display device
Inventor: SAKAMOTO TSUTOMU
IPC: H04N5/66
Filed: 1992-06-22
Abstract: PURPOSE:To reduce the capacity and cost of a gamma(gamma) compensating circuit. CONSTITUTION:A gamma compensation table 25 converts an 8-bit video signal into a 4-bit upper compensation value and applies the value to an adder 33. Each of plural gamma compensation tables 26 to 31 converts the 8-bit video signal into a 7-bit lower compensation value and applies the converted value to the adder 33 through a switch 32. The adder 33 constitutes upper 4 bits out of a 10-bit output by the most significant bits of the upper and lower compensation values and constitutes lower 6 bits out of the 10-bit output by the 1st to 6th bits of the lower compensation value. The switch 32 is controlled by the temperature of a liquid crystal panel to select one output from any one of tables 26 to 31. Since the video signal is divided into an upper compensation value and a lower compensation value, the number of bits can be reduced and the capacity of the gamma compensation tables can be reduced.

Filed: 1993-07-01
Abstract: PURPOSE:To provide a TAB type semiconductor device, mountable on circuit boards by solder reflow, that allows the reduction of number of components and the simplification of structure for the reduction of material cost and assembling man-hour. CONSTITUTION:A TAB tape that retains a semiconductor chip 1a through leads 9, is put along and stuck to the circumferential surface of an insulating plate 8 surrounding the semiconductor chip 1a. Terminal sections 9a, that is, one ends of the TAB tape leads 9, are exposed to the rear of the insulating plate to form external terminals. This makes it unnecessary to form external terminals on a semiconductor chip housing case or previously provide an insulating plate with external terminals as conventional. Further, the above-mentioned method eliminates the need for a process to partially peel an insulating sheet off a TAB tape. The semiconductor chip 1a is covered with a resin film member 12 for its retention.
