Inventor: SHIGEHARA HIROSHI
IPC: G06F7/505
Filed: 1987-02-21
Granted: 1990-08-20
Abstract: First and second binary data is multiplied in 2's complement format and a predetermined number of significant bits of the actual multiplication result are deleted to obtain a virtual multiplication result. An adder/subtractor performs addition/ subtraction of the third binary data and the fourth binary data in 2's complement format in response to a control signal. The most significant bias of the third binary data is the virtual multiplication result and a number of lower bits of the third binary data are an inverted most significant bit of the virtual multiplication result. The inverted most significant bit of the virtual multiplication result is supplied to the adder/subtractor as the least significant bit when the adder/ subtractor operates in an adder mode.

Title: Method of manufacturing structural foam
Inventor: KIM DO-HYONG
IPC: B29C45/76
Filed: 1991-11-21
Granted: 1994-12-07
Abstract: The structural foam is manufactured by foaming the plastic row material with foaming agent to be used for a construction material. The foam has many holes in inner part and non-foamed skin. In conventional injection molding, the difference of pressure between a cylinder and a mold causes the surface inferiority owing to the gases during the foaming. In order to improve the workability, the mold is presealed before the injection starts and the mold pressure is controlled to show the same pressure as that of the injector cylinder and then the pressure is maintained until the mold is filled to about 80-90 % with resin. The foaming is started by decreasing the mold pressure to atmosphere for structural foam manufacture.

Abstract: A process for forming a fine contact of a high integrated semiconductor element such as a DRAM, a SRAM, or an ASIC which requires a fine pattern is disclosed. In the process, a first insulating film(7), a second insulating film(8), and a polysilicon film(9) are sequentially deposited at an upper portion of a wafer. A mask pattern of a sensitive film(20) is formed at an upper portion of polysilicon film(9). Polysilicon film(9) and second insulating film(8) are sequentially dry etched. A portion of first insulating film(8) is etched. Sensitive film(20) is removed. A space polysilicon film(10) is formed at a side wall of portions in which first insulating film(7),  second insulating film(8), and polysilicon film(9) are etched.  Material on a desired contact portion(6A,6B) is etched by using space polysilicon film(10) as a mask to form contact holes(22,23).
