Inventor: LEE DONG-KIL
IPC: H04N5/76
Filed: 1991-07-08
Granted: 1993-12-24
Abstract: The method involves receiving current time  information,  and recording a program whose  pre-programmed  time  is  the  earliest among the reserved programs. The pre-programmed time of  the  next program in the same block is compared with those  of  programs  in other block, and the next program is recorded at  the  appropriate time and the block time comparison is repeated  to  establish  the next successive program to be recorded. The  section  length  from the reserved recording section of the next program to the starting point of a  corresp.  program,  is  calculated  when  the  program pre-programmed time in another block is earlier than that  of  the next program in the same block. A fast forward function shifts  to the recording position of the corresp. program for the duration of the calculated  section.  The  block  programs  are  analysed  and arranged according to content.

Abstract: double-standard signal receiving units for extracting a clock by inputting main and spare signals to be used as reference signals of a synchronization circuit; double-standard signal loss detecting units for detecting a loss state of the main and spare signals so that the double-standard signal receiving units can have a switch function of a ratio of 1:1; a reference clock loss detecting unit for detecting a reference clock under connection with the double-standard signal receiving unit; double-reference clock generating units for selectively outputting the other reference clock in addition to a control signal provided from the reference clock loss detecting unit; double-system clock generating units for generating a system clock by inputting outputs of the double-reference clock generating units; an operating mode detecting unit for detecting a phase synchronization state of the system clock generating units whose input terminals are connected with the double-system clock generating unit, respectively; and a system clock selecting unit for switching a stable clock of two outputs from the double-system clock generating units through an input of the control signal of the operating mode detecting unit.

Title: Injecting apparatus for fuel pump
Inventor: LEE YANG-RO
IPC: F02M37/00
Filed: 1993-04-03
Granted: 1995-03-23
Abstract: The apparatus improves a fuel discharge efficiency by modifying the structure of upper/lower case and an impeller sucking the fuel from a fuel tank and supplying it for the engine. The apparatus comprises the impeller(100) rotated between the lower case(200), having a fuel suction groove(210), and the upper case(300), having a fuel discharge groove(310); a plurality of impeller grooves(110) equidiatantly formed on the circumference of the impeller(100); inducement means(120), prepared on the impeller grooves(110), causing the suction force; a ring shape body(130) inserted into the outer circuference of the impeller(100).

Granted: 2001-10-22
Abstract: PURPOSE: A liquid crystal display and a driving method thereof are provided to a correction voltage for a predetermined period to a line electrode driving signal for correcting a gray voltage and delaying a column electrode driving signal for the predetermined period, thereby realizing erroneous gray scale. CONSTITUTION: A liquid crystal display includes a line gray voltage control element(331) for providing a predetermined period for correcting a gray voltage to a line electrode driving signal, and a column gray voltage control element(351) for generating a column electrode driving signal corresponding to a signal section generated by the line gray voltage control element.
