Patent KR-900003434-B1 (KR)
Title: Mulching devices for a lawn-mower
Inventor: MOULIN EDWARD DU
IPC: A01D42/00
Filed: 1987-05-09
Granted: 1990-05-19
Abstract: There is provided a mulching arrangement for a rotary motor lawn- mower. The attachment comprising a base plate upon an upper surface of which a rotary motor lawn-mower is removably mountable. A feed hopper is attached and adapted to receive vegetable matter to be converted into mulch. The feed hopper is in communication with the upper surface of the base plate via a feed passage which is so formed and mounted relative to said base plate. On operation of the lawn- mower a vibrating moment is imparted from the mower and base plate to said feed passage. This minimizes or avoids clogging and blocking by vegetable matter passing therethrough.

Title: Method of fabricating interconnect layers on integrated circuit chip using seed-grown conducts
Inventor: JEAN-MARIE GUTIERREZ
IPC: H01L21/285
Filed: 1987-07-28
Granted: 1996-06-26
Abstract: A process of forming an interconnection layer for an integrated circuit in which the conductor pattern is embedded in a layer of insulating material to form a conductor-insulator layer. The conductor-insulator layer is formed by selectively filling recesses in a layer of insulating material with conductive material. The filling of the recesses is accomplished in two steps: depositing an initial layer of conductive material by a process which selectively deposits the conductive material on a seed material located in the bottom of the recesses, then depositing the bulk of the conductive material by a process which selectively deposits conductive material on existing conductive material.

A demultiplexer is coupled to the receiver and the memory for demultiplexing the signal to recover one of the number of phases in response to the predetermined information and the baud rate. The selective call receiver also includes a decoder coupled to the demultiplexing means for decoding said one of said number of phases of said signal to derive a selective call message therefrom.

Patent KR-970002875-B1 (KR)
Title: Low free formaldehyde methylol hydantoin compositions
Inventor: FARINA THOMAS E
IPC: A61K31/415
Filed: 1993-05-20
Granted: 1997-03-12
Abstract: Compositions of dimethyloldimethylhydantoin, monomethyloldimethylhydantoin, and dimethylhydantoin having less than 0.1% by weight of free formaldehyde based upon 100% by weight of total composition; and wherein the weight ratio of dimethyloldimethylhydantoin to monomethyloldimethylhydantoin ranges from about 1:1.25 to about 3.5:1, are provided. These compositions may be prepared (1) by reacting dimethylhydantoin and a formaldehyde-containing source wherein the molar ratio of formaldehyde to dimethylhydantoin ranges from about 1.2:1 to about 1.55:1 or (2) by admixing (a) from about 80 to about 90% by weight of an aqueous solution of methyloldimethylhydantoin having greater than about 0.1% by weight of free formaldehyde with (b) about 20 to about 10% by weight of dimethylhydantoin based upon 100% weight of aqueous dimethyloldimethylhydantoin solution and dimethylhydantoin combined.

Title: 공간스테레오신장기를갖는음성신호처리장치
IPC: H04H20/88
Filed: 1993-08-26
Granted: 2002-06-26
Abstract: 본 발명은 각각의 스피커에 좌측 및 우측 스테레오 사운드 채널을 갖는 스테레오 음성 처리 시스템(20,26,24,28)에 관한 것이다.  상기 시스템에는 서로 이격된 제 1 쌍의 스피커(30)들이 청각적으로 실제보다도 훨씬 더 이격된 것처럼 들리도록 스테레오 사운드의 공간 신장이 제공된다.  음성 시스템에는 제 2 쌍의 스피커들을 접속시키기 위한 설비(40)가 제공되는데, 상기 제 2 쌍의 스피커들은 그 이격된 거리가 제 1 쌍의 스피커들보다도 크게 되도록 배치된다.  이러한 2 차적인 스피커가 사용될 경우에 음성 시스템에는 공간 신장이 없는 스테레오 사운드를 제공하는 장치가 제공된다.
Patent KR-960012149-B1 (KR)
Title: Expansible anchor of metal and a process for the manufacture thereof
Inventor: WOLFGANG HENGESBACH
IPC: F16B13/06
Filed: 1993-10-28
Granted: 1996-09-16
Abstract: The expansion anchor comprises a shaft (1) which exhibits, at its rear end, means for fastening an object and, at its front end, a cross-sectionally reduced portion (3) with an adjoining expansion cone (4), and it further comprises an expansion sleeve (5) which is pushed over the said portion and has longitudinal slits (6) and locking elements (7) which project beyond the diameter of the expansion sleeve (5). The locking elements are a plurality of continuous punched-out portions running in the longitudinal direction of the expansion segments. The punched-out portions are each in the form of a triangle with the point directed towards the front end of the expansion segments. The contour of the projected development of the expansion sleeve is initially punched out in slight under-size, and the sheet metal is then compressed in its thickness in a pressing procedure. The locking elements are punched out after the compression. <IMAGE>

Title: Metal doped control method for life time killer
Inventor: JUNG WOOK-JIN
IPC: H01L21/22
Filed: 1993-12-10
Granted: 1997-05-23
Abstract: A method of controlling the concentration of a metal impurity used for the lifetime killer for determining the switching time of a semiconductor power device includes the steps of evaporating metal impurities (Au, Pt) on the rear surface of a silicon wafer, and carrying out rapid thermal diffusion process using RTP in the ambient of nitrogen at 1000 deg. C, to allow the metal impurities to reach the front of the silicon wafer, which will be used to be the active region of the power device.
