Patent KR-890004507-B1 (KR)
Title: Device for preventing electromagnetic wave in microwaves range
Inventor: JIN SOK-UNG
IPC: H05B6/76
Filed: 1986-11-29
Granted: 1989-11-06
Abstract: The device, which is used for preventing microwave oven from leaking microwave energy through a gap between a front plate and a door, comprises a seal plate (4) on inner wall (1') of a door frame (1) in a parallel direction with the front plate, and an opening part where a gap between a center line (5') and the inner wall (1') is formed as widely as λ/4.  A distance between an outer wall (1") and the center line (5') is  λ/8 wide.  Using other microwave absorbing material is unnecessary, and the microwave leakage at right angle or a certain inclined angle is prevented.

Title: Automatic focus and exposure controlled camera
Inventor: RASCHKE KLAUS
IPC: G03B9/24
Filed: 1987-02-05
Granted: 1990-03-12
Abstract: Automatic focus and exposure control mechanisms are coupled to a shutter release member.  Cocking of a spring-driven slide against springs causes simultaneous cocking of a spring-driven exposure control against a further spring.  Upon release, the shutter slide first moves slowly under the control of a velocity limiter to control the movement of a rotatable focus drive sector gear and a pair of control pawl springs.  After focus and exposure setting has been effected by a regulator the slide is released from a limiter to move rapidly and effect shutter release.

IPC: H01J31/12
Filed: 1992-03-03
Granted: 1994-12-23
Abstract: The method includes the steps of depositing a cathode pattern (5) of column electrodes on a back glass plate (3), chemically depositing an insulating layer (7) on the cathode pattern (5) to deposit a gate (6) of row electrodes on the layer (7), depositing an insulating layer (41) on the whole FED structure, applying a photosenstive layer (42) on the layer (41), repeatedly exposing and etching the photosenstive layer (42) and dielectric layer (41), by using masks, to form a spacer (40) before the formation of the microtips (9) and gate (6), thereby preventing the microtips and gate caused by the surface-contamination.

Title: Board of preventing noise made by polyvinyl
Inventor: LEE KUN-HUI
IPC: E01F8/00

Granted: 1995-02-06
Abstract: Sound waves generated from motors collides against blades (2) of the panel to reflect. The reflected sound also collides in crossing in the same cup (1) for gathering sound. After that, this reflex action is repeated for the reflected sound to pass holes (6) to finally come in to air pockets (5)(7). Sounds are finely broken by repetition of refex action in the single concave cup (1) for gathering sound. Soundproofing effect is produced because the reflected gathered sounds are absorbed in air pockets (5)(7).

Title: Production of natural insecticidal component fraction
Inventor: HAN CHANG GYUN
Filed: 1992-12-23
Granted: 2001-01-15
Abstract: PURPOSE: A process of preparing an insecticidal component fraction is provided by extracting finely ground ginkgo leaves in an aqueous solution of lower alcohol and then dissolving the obtained crude fraction of an insecticidal component in lower ketone. Whereby, the insecticidal component exerts no influence on human body or environment. CONSTITUTION: Ground ginkgo leaves are extracted in an aqueous solution of lower alcohol and 25 to 35%(w/v) of the crude extract of ginkgo leaves are extracted in a nonpolar solvent selected from ethyl acetate, dichloromethane, chloroform, carbon tetrachloride and hexane to produce a crude fraction of a natural insecticidal component, which is dissolved in lower ketone selected from acetone and methyl ketone and added with activated carbon, followed by agitation for 60 to 90min.

Title: Initial synchronization arrangements for parallel partial correlator
Inventor: KIM DAE-HO
IPC: H04L7/10
Filed: 1992-12-29
Granted: 1995-05-03
Abstract: The system comprises a parallel partial correlator(21) for partially correlating received signals and PN codes in parallel to output the correlating result, an integrator(23) for integrating output of a low pass filter(22), a comparator(24) for comparing threshold with output of the integrator to output the compared result, and a synchronization controller(25) for outputting an initial synchronization identification signal if the output of the integrator(23) is bigger than threshold.
