Abstract: 본 발명은 두개의 전화선(국선)을 사용하는 전화기에서의 착신자의 전화를 자동으로 전환시킴과 동시에 키폰전화기에 가고자 할 장소에 특정의 전화번호를 입력시킨 후 그 키폰전화기에 착신자의 전화가 걸려오면 입력된 전화번호의 곳으로 전화를 자동으로 걸 수 있게 하는 전화기에서의 착신 전환 방법 및 회로에 관한 것이다. 종래의 전화기는 착신자로 하여금 전화가 걸려오면 자기가 있는 곳으로 착신자의 전화를 전환시킬 수 있는 회로가 없기때문에 착신자로 하여금 일정시간후에 다시 전화를 걸어야 하고, 착신자의 전화를 받는 경우 그 착신자의 통화내용이나 그에 따른 약속장소와 전화번호를 일일이 메모해야 하는 문제점과 또 간이교환장치에 사용되는 키폰전화기는 사용자가 자리를 옮기는 경우 긴급한 용무로 키폰전화기에 걸려온 전화를 받지 못하는 문제점이 있었다. 
     본 발명은 제1도에서와 같이 두개의 전화선(국선)을 이용하여 외출시에 자기가 있는 곳의 전화번호를 기억시켜서 착신자로 하여금 전화가 걸려오면 전화번호를 기억시켜 놓은 곳을 다른 한개의 전화선을 통해 착신자의 전화를 자동전환시킬 수 있게 하고, 또 제4도에서와 같이 키폰전화기에 가고자 할 장소에 특정의 전화번호를 입력시킨 후 그 키폰전화기에 착신자의 전화가 걸려오면 입력된 전화번호의 곳으로 전화를 자동으로 걸어 착신 전환할 수 있게 한다.

Title: Deflecting yoke for cathode-ray tube
Inventor: KIM HU-DUK
IPC: H01J29/76
Filed: 1990-11-27
Granted: 1993-02-20
Abstract: The deflection yoke for cathode ray tube is composed of  5-30 wt.% magnetic material, 60-90 wt.% resin and 1-5  wt.%  elastomer. The magnetic material is selected from rare earth  metal  systems, SmCO5 or Sm2 (CoFeCuM)17. Where M is Zr, Ti or HF. The resin is chosen from epoxy resin, nylon resin or polyolefin  resin.  The elastomer is rubber. The yoke shows a strong magneticity and makes little difference in magnetic characteristics with  the  variation of temperature.

Title: Process for the preparation of phosphor for color cathode-ray tube and devices therefor
Inventor: KIM UNG-SU
IPC: C09K11/00
Filed: 1990-12-31
Granted: 1994-01-07
Abstract: The fluorescent material having a high luminance is produced by (a) putting a mixture (12) of Y2O3, Eu2O3, K2HPO4, Na2CO3 and S into the inner of the aluminium oxide crucible (11) of 500 ml volume, (b) putting a mixture of water and S into of the aluminium oxide crucible (14) of 1000 ml volume housing the crucible (11), and (c) firing the cnucible (14) at 1200 deg.C for 2 hr. The sulphur (S) acts as a catalyst in the production of the fluorescent material of (a) process, and it generates a reduction atmosphere in the firing process (b).

Title: Automatic vehicle tracing system with emergency call function
Inventor: PARK HYON-CHOL
IPC: G01S1/02
Filed: 1990-12-31
Granted: 1993-06-23
Abstract: The system tracks the vehicle in real time, and receives  the emergency relief demand signal from  the  vehicle.  The  automatic vehicle tracking  system  comprises  a  frequency  converter  (50) converting modulated POCSAG code into  middle  band  frequency;  a demodulator (21) demodulating the middle band frequency; a  POCSAG decoder (22) decoding the  address  included  in  the  demodulated POCSAG signal, comparing the address with  a  built-in  data,  and generating flags; a logical means (53) receiving  the  flags  from the decoder (22) and transmitting  control  signals;  a  modulator (54)  modulating  the  transmitted  control  signals;  a  PN  code generator (34) controlled by the logic means (53);  a  multiplexor (35) selecting emergency messages.

Title: Distributed parallel processing network
Inventor: FILKEN DAVID L
IPC: G06N99/00
Filed: 1990-08-18
Granted: 1993-05-27
Abstract: A parallel distributed processing network of the back propagation type is disclosed in which the weights of connection between processing elements in the various layers of the network are determined in accordance with the set of steady solutions of the stiff differential equations governing the relationship between the layers of the network.
