Title: The making method of gas valve
Inventor: SOK YUN-KI

Granted: 1992-07-25
Abstract: A plastic working apparatus to  make  T-shape  tubes  of  gas lighters comprises a cutting die, a first die and a second die.  A round bar is cutted to a length by the cutting die so as to have a volume equivalent to the volume of a T-shape tube, and is inserted to the tapered entrance of the second die. Then the round  bar  of cutting is compressed by both dies. While a first pin in the first die is compressing the round bar, the  first  die  is  moved  off. After that the round bar is transformed into  a  T-shape  tube  by successive plastic forming steps. The round bar is a copper alloy. This plastic forming  method  is  simpler  and  cheaper  than  die casting in making the T-shape tube of gas lighter.

Abstract: Disclosed is a compact disc play-back method. The method includes a first step which controls a first focusing operation, a second step which judges whether a disc area is a data area or not when the focusing is on at the first step, a third step which controls a tracking if the disc area is a data area at the second step and tries reading of TOC and then performs a normal play-back operation if it succeeds to read TOC, a fourth step which judges the disc area if it fails to read TOC and continuously tries the TOC reading if it is a data area from the result of the judgement at the third step and if it is not data area moves an object lens so that a pick-up means can approach to a data area, a fifth step which controls to move of the object lens and the feed motor so that the pick-up means can approach to the data area, a sixth step which performs a normal play-back operation if a data search succeeds after track jump in a long jump mode, and a seventh step which tries a continuous search if the data search fails and it is data area, and if it is not data area make the pick-up means approach to the data area by moving the object lens and the feed motor. Thus, disc congestion can be prevented.

Title: Wide screen tv
Inventor: KIL DONG-SON
IPC: H04N7/01
Filed: 1992-09-16
Granted: 1995-08-25
Abstract: The additional channels are displayed on the blank area of a wide screen TV set by 4:3 mode. The TV includes a main memory(4) for storing 4:3 video signal with a specified recording frequency(fwc), POP memory(12) for storing decimated POP video signal, a RGB processor(15) for processing data stored in the POP memory and the main memory to generate 16:9 RGB signals, and a microprocessor(16) for controlling the memories and a tuner.
