Title: Method and apparatus for dry etching of silicon nitrode film
Inventor: HAYASAKA NOBUO
IPC: H01L21/302
Filed: 1987-05-30
Granted: 1990-06-18
Abstract: Dry etching of a silicon nitride film, formed on a silicon dioxide film on a substrate, is carried out using a gas contg. fluorine and other halogens, at least the fluorine being activated in a region separated from the etching vessel to obtain an active species which is fed into the etching vessel for etching the silicon nitride film selectively w.r.t. the silicon dioxide film. The process is useful in semiconductor mfr. Use of activated fluorine species and another halogen gives high etching selectivity while maintaining a sufficiently high silicon nitride etching rate.

Title: Method for preparation of novel immobilized biocatalysts
Inventor: HARDER ABRAHAM
IPC: C12P1/00
Filed: 1986-11-17
Granted: 1995-10-21
Abstract: Immobilized water-insoluble biocatalysts in particulate form comprise living cells, particularly yeast, dispersed in a cross-linked gelling agent. An enzyme, particularly amyloglucosidase, may be co-immobilized in the particles. These particles are prepared by suspending the living cells in an aqueous solution of a gelling agent, dispersing this suspension in a water immiscible organic liquid to form a suspension in the liquid of aqueous particles comprising the living cells and gelling agent, gelling the gel and cross-linking the gelling agent. It is found that when living cells such as microbial cells and especially yeast are immobilized in this way, that surprisingly, not only is their viability retained, but the ability of yeast cells to produce ethanol under continuous fermentation conditions is significantly improved. Specific strains of Saccharomyces cerevisiae, suitable for immobilization in this way, are described.

Inventor: MUN YONG-U
IPC: B63B39/02
Filed: 1991-09-10
Granted: 1994-02-23
Abstract: A rolling attenuator is disclosed in which additive weight switches are used to increase the volume of one of volume varying means and to decrease the volume of the other one, a shutter on the volume increasing means is closed, the other shutter is opened so that the balance of fluid is destroyed to shift a balance weight toward the wave, thereby preventing the overturn of ships.

Title: Current mirror sense amplifier
Inventor: JANG SONG-JUN
IPC: G11C11/407
Filed: 1991-10-19
Granted: 1994-06-22
Abstract: The current mirror sense amplifier includes a first MOS FET connected between a common connection point of a first sense circuit and a second MOS FET to receive the output of a second sense circuit through its gate; and a third MOS FET connected between a common connection point of the second sense circuit and a fourth MOS FET to receive the output of the first sense circuit through its gate, thereby reducing the power consumption of a sense amplifier.
Patent KR-950007488-B1 (KR)
Title: Starilization method and apparatus of laser frequency and power
Inventor: SHU HO-SONG
IPC: H01S3/10
Filed: 1991-11-19
Granted: 1995-07-11
Abstract: The method uses the secondary beat signal among three longitudinal modes as a distinguish signal for stabilising the laser frequency and power output, stabilises a length of a resonator at A point or B point according to the usage state of an inverting amplifier in an automatic controller; and can select the stabilised single mode by operating a second polarizing element.
Patent KR-100192115-B1 (KR)
Title: Interstage casing for a pump made of sheet metal and method of manufacturing the same
Inventor: KAJIWARA KEN-ICHI
IPC: F04D1/06
Filed: 1991-12-24
Granted: 1999-06-15
Abstract: An interstage casing made of sheet metal includes a cylindrical receptacle-like body having a bottom wall (24) on an end thereof and an open end opposite to the end. The open end has an axial end surface (22) and a radially inner surface (23) which serve as a member of a spigot joint to be joined to a next interstage casing. The cylindrical receptacle-like body also includes a cylindrical side wall (21), a cylindrical portion (25) joined between the bottom wall (24) and the cylindrical side wall (21) and having an outside diameter slightly smaller than an inside diameter of the open end, and a flat portion (27) joined to the recessed portion (26) and serving as an end surface of the bottom wall (24). The flat portion (27) is adapted to be engageable with the end surface of the open end of an adjacent interstage casing. The flat portion (27) has an outside diameter slightly larger than an outside diameter of the open end. The interstage casing further includes a recessed portion (26) joined to the cylindrical portion (25) and smaller in diameter than the cylindrical portion. The recessed portion provides a space for installing an O ring (31) therein.
