Title: Process of forming foundry cores and molds
Inventor: DUNNAVANT WILLIAM R
IPC: B22C9/02
Filed: 1980-12-21
Granted: 1984-05-18
Abstract: Foundry cores and molds are produced by mixing a foundry granulate with an ethylenically unsatd. monomer and/or polymer binder, shaping the material, and polymerising the binder with a radical initiator that is an organic peroxide and a catlyst.  This process is used esp. for cold-box prodn. of foundry molds and cores for casting light metals, esp.  Al.  The molds and cores have good mechanical strength and excellent breakdown properties, give very good cast surface quality, and can be hardened rapidly to give a high prodn. rate.  The initial granulate / binder mixt. has a long shelf life.

     상기한 목적을 달성하기 위해서, 본발명에서는, 전화국의 교환기와 이용자가정의 전화기를 접속하는 전화망의 유휴시간에, 이 전화망을 거쳐서 국외의 센터로부터 이용자가정에 방송데이터를 전송하도록 한 통신장치를 전제로 해서, 패킷통신에 의해 센터와 이용자가정과의 사이에서 일대일의 쌍방향통신을 행하고 있다. 
     일대일의 쌍방향통신이 가능하게 되므로, 관제장치로부터 특정한 단말장치로의 다운로드데이터의 송신, 및 특정한 단말장치로부터 관제장치로의 입로드데이터의 송신이, 단말장치사이의 혼신없이 행하여져서, 예를들어, (a)관제장치로부터 특정한 단말장치로 다운로드데이터를 전송하고, 이 다운로드데이터가 단말장치에 정확하게 도달하여 있는지 어떤지를 업로드데이터에 의해 센터에서 확인하는 것, (b)단말장치로부터의 음악의 요구, 명령을 업로드데이터로서 센터에서 받아들이는 것, (c)관제장치와 단말장치와의 사이에서 에러가 없는 통신을 행하기 위한 포로토콜을 구축하는 것 등이 가능하게 된다.

Title: Signal transmission method of wire remote controller
Inventor: KIM YONG-BUM
IPC: H04Q9/00
Filed: 1992-10-08
Granted: 1996-02-26
Abstract: a) connecting I/O ports(I1, O1) of a main microcomputer(10) and ones (I2, O2) of a microcomputer(20) of remote controller in reverse each other; and b) connecting both of ports for driving voltage(VCC) and ground(GND) respectively. The data values of zero and I according to transmission of 8 bit data are recognized as high and low levels in sequence of time so that the command transmission is performed.

Title: Insulation tank and constructing method thereof
Inventor: KIM KYONG-JU
IPC: B65D90/06
Filed: 1992-12-08
Granted: 1995-05-04
Abstract: The heat-insulated tank applied for the steam accumulator, hot-water storage tank, cryogenic tank, enables to increase the heat insulation performance and reduce the constructional cost. The tank comprises a fluid storage tank (11); a lattice-type frame (16) fixed by fixing means and separated from the circumference of the tank (11) at a certain distance; a plurality of plates (12) mounted on the respective lattices of the frame to form a space between the plate and the circumferences of the tank; heat insulation material (13) filled in a gap between the circumference and the plate (12).

Title: Electric control type steering system
Inventor: JO SONG-HYON
IPC: B62D5/06
Filed: 1992-12-31
Granted: 1995-04-28
Abstract: The device for variously controlling the power steering force according to the vehicle speed, reduces the steering force for simplifying the manipulation of the handle in low-speed and increases the running stability of the vehicle at high-speed. The device comprises the power cylinder having the primary/secondary oil chambers divided by a piston; a supply passage for supplying the hydraulic oil of the oil tank to the oil chambers according to the steering directions; a rotor valve for controlling the flow direction of the oil at the steering or non-steering state; a leak passage between the supply passage and the return passage for returning the oil to the oil tank; a proportional solenoid valve for controlling the flow; a vehicle speed sensor; an electronic controller for controlling the opening of the solenoid valve.
