Patent KR-860000646-B1 (KR)
Title: Method and device for forming bell-like section of single wall to double wall pipe
Inventor: LUPKE MANFRED A A
IPC: B29C48/13
Filed: 1983-10-26
Granted: 1986-05-28
Abstract: The appts. includes a travelling mould with a cavity having a corrugated section sepd. by bell sections. Single wall bells are formed in a double wall thermoplastics pipe by moulding an outer wall to provide corrugated sections sepd. by bell sections and extruding a smooth inner wall into the outer wall. The inner wall is not subjected to the action of an internal presser and is removed wholly or in part from the bell section after the pipe is fromed. As the pipe cools, the air pressure in the chamber between the outer and inner walls reduces considerably tending to collapse the outer wall.

Title: Silicate compound removing method from iron pickling waste liquid
Inventor: HURUSHO GENGI
IPC: C02F1/28
Filed: 1984-11-07
Granted: 1990-07-31
Abstract: The waste liquor is passed downwards through an adsorption bed of filled adosrbent substrates (ceramic or organic mouldings, net plate of fiber or spherical fiber fillers). The adsorption is initiated at the top and continued through the bed. The voids between the substrates are uniformly distributed and the substrates preferably have a surface area sufficient for adsorption and a passage cross section sufficient to allow flow of the liquor without clogging occurring for at least two months. The method is used in regenerating the waste pickling liguor into HCl for reuse and the high purity inon opide for prodn. of ferrites and pigments.

Abstract: In an N-type substrate (21), a P-minus diffusion region (22) about 3 microns thick is formed at the time of fabrication of transistor wells, with P+ contact regions (23) for a resistor and diode. A field oxide layer (24) isolates other circuit elements, and about 350 angstrom units of gate oxide (25) underlie a polysilicon layer (26) which operates as a series resistor between the I/O pad and circuit. The polysilicon layer is convertd with a thin layer of thermal oxide (27) to prevent P diffusion from a phosphosilicate glass covering (28). Contact holes (29) are connected by aluminium wiring patterns (30).

Filed: 1986-10-15
Granted: 1990-08-01
Abstract: A light beam is projected on a reference plane (5) and an object (6) to be measured. A drive voltage causes a change of phase difference when applied to the phase shifter (8). The magnitude of phase shift of the reflected lights is detected by a phase shift detector (13) on the basis of the drive voltage at a point of time at which the change of the phase difference of the reflected lights has been compensated. An up or down pulse is generated by an up-down pulse generator (22) upon detecting a discontinuous change in the magnitude of phase shift attributed to displacement of the object to be measured. A pulse is generated by another pulse generator (31) upon sensing a change in brightness of an interference signal also attributed to object displacement.

Patent KR-100214894-B1 (KR)

IPC: H01L29/167

Abstract: 마이크로미터 근방 또는 마이크로미터 이하의 채널 길이를 가지며, 핫-캐리어의 발생을 야기하는 상태하에서 동작되도록 설계된 MOSFET 소자는 게이트 산화물-실리콘 계면(18)에서 실리콘 기판(12)에 탄소가 도우핑된다. 산화물-실리콘 계면은 수소 원자를 포함할 수 있다. 이들 수소 원자는 대부분 탄소 원자에 결합되며, 실리콘에 결합되는 것보다 더 강하게 탄소 원자에 결합되어, 그 결과, 핫-캐리어들이 수소 원자를 분열시켜 계면에서 핫-캐리어 포획 장소를 형성할 가능성이 적게 된다. 따라서, 핫-캐리어 경시 변화가 실질적으로 감소된다. 이러한 능력은 마이크로미터 이하 크기의 소자에서 특히 유용하며, 정상동작 전압을 낮출 필요가 없게 한다.

Patent KR-930007673-B1 (KR)
Title: Method of substituting memory unit with deficiency
Inventor: KAWASHITA ASAYOSHI
IPC: G11C29/00
Filed: 1990-11-30
Granted: 1993-08-18
Abstract: An external storage apparatus which includes a recording medium on which a replacing area or defective spare block area is used in place of a defective block. Reassignment processing of the replacing area to the defective block is performed under a command issued by a host system. A managing unit manages the number of blocks remaining unused in the replacing area. Upon reception of the command for assigning the replacing area to the defective block from the host system, the reassignment processing of the defective block from the host system, the reassignment processing of the defective block is performed, and the number of blocks remaining in the replacing area which is managed by the managing unit is supplied to the host system.
