Patent KR-930008167-B1 (KR)
Title: Method and apparatus for preventing the copying of a video program
Inventor: RYAN JOHN O
IPC: G11B27/024
Filed: 1987-07-16
Granted: 1993-08-26
Abstract: A video signal is modified so that a television receiver will still provide a normal color picture but which a video tape recorder will detect and prohibit its being recorded. A plurality of ordered pairs of pseudo-sync and positive pulses are added to the video signal vertical blanking interval following the normal sync pulse. A disabling circuit (22) in a video tape recorder (10) detects the modified signal. This detection may be by comparing the voltage differential between the pseudo-sync pulse tip and the positive pulse relative to the normal voltage differential between the sync pulse tip and the back porch of the blanking interval. Alternatively, the modified signal can be detected by identifying the pulse frequency of the signal in the blanking interval. A high frequency is indicative of the presence of the modified signal. A control signal (26) is produced by the disabling circuit (22) when the modified signal is present, and this disables a recording device (20). If no modified signal is detected, the recording device is enabled.

Title: Arrangements for neon lamps
Inventor: LEE MYUNG-JUN
IPC: H05B41/30
Filed: 1988-02-04
Granted: 1990-09-21
Abstract: The start circuit uses a ferrite core as a high voltage transformer in which the primary winding is supplied with 20 KHz power and provides output current of 25 mA or greater one. The input voltage rectified by a bridge type rectifier (1) is stored in a condenser (C4) for triggering a SCR (SCR2) through a diode (TD). When the SCR is turned on, a dividing resistor (R7) voltage drops and a condenser (C3) triggers a SCR (SCR1) simultaneously. At this time, the secondary winding provides high voltage to start the Neon lamp and the induced voltage is generated at the primary winding also.  The induced voltage biases a transistor (Q3) to bypass the condenser (C4) voltage and a condenser (C2) provides inverse voltage to the SCR5(SCR1-2) to turn off them.

Abstract: A flexible disk cassette (20) is provided and includes improved means for stabilizing flutter of the disk upon rotation of the latter within the cassette, particularly at the access slot (60;74) where the disk may be coupled to read/write heads for data recording or reproduction. The cassette includes a flexible data storage disk (30) coated on both sides with a data storage recording medium and a pair of cleaning liners (86;88) each positioned on a respective side of and in selective contact with the disk. The disk, sandwiched between the liners, is positioned in the cassette between a pair of spaced-apart covers (22;24) bonded to one another. Respective radially extending access slots are provded in the covers to provide access of the read/write heads to the data storage medium on the disk. Positioned adjacent each radial edge of the access slot and facing the respective liner is a flat-surfaced, raised portion or land (78;80;64;66). Respective pluralities of spaced apart, radially extending ribs of uniform height are formed on the inside surface of each cover in opposed, interdigitated reiation, the respective planes of the surfaces of each plurality of ribs being spaced apart to accommodate the liners and disk while positioning the liners in selective contact with the disk to effect stabilization while maintaining torque necessary to rotate the disk at an acceptable level.

Abstract: Y signals are sampled to twice of [constant of about 570  x fH , and these Y signals are converted to 0-7.2  MHz  by  removing the high pass components. C  signals  are  sampled  to  a  carrier frequency of [constant of about 570 x fH  to form signals of 7.5 - 9.5 MHz. These separated Y and  C  signals  are  loaded  to  two carrier waves, and the overlapped portions  are  allowed  to  pass through,  so  that  the  transmission  of  high  resolution  video signals, which is compatible with the NTSC  method,  is  possible. The Y signals  including  YH  signals  are  demodulated  from  the transmitted modulated signals, thereby obtaining  high  resolution video signals.

Title: Method for making a metal matrix composite of directional solidification metal
Inventor: AGHAJANIAN MICHAEL KEVORK
IPC: B22F3/26
Filed: 1989-10-10
Granted: 1997-12-03
Abstract: A metal matrix composite is formed by contacting a molten matrix alloy (18) with a permeable mass of filler material or preform (16) in the presence of an infiltrating atmosphere. Under these conditions, the molten matrix alloy (18) will spontaneously infiltrate the permeable mass of filler material of preform (16) under normal atmospheric pressures. Once a desired amount of spontaneous infiltration has been achieved, or during the spontaneous infiltration step,the matrix metal which has infiltrated the permeable mass of filler material or preform (16) is directionally solidified. This technique allows the production of spontaneously infiltrated metal matrix composites having improved microstructures and properties.

Granted: 1994-09-09
Abstract: In an active matrix type liquid crystal display device which drives liquid crystal by applying voltage via a thin film transistor to each of transparent display electrodes (15) arranged in a matrix form, source buses (19) are each composed of a transparent conductive bus (19A) formed by a transparent conductive layer extending along each column of the display electrodes (15) and a metal bus (19B) formed by a high melting point metal layer overlapping and extending along the transparent conductive bus (19A). An insulating layer (23) is coated almost all over the surface of a base plate (11) on which the source buses (19) are disposed. The insulating layer has slot-like windows (19D) each extending along one side of each display electrode (15) so that the surface of the corresponding metal bus (19B) is partly exposed. A bus segment (19C) formed by a conductivity metal layer fills each slot-window (19D) to make direct contact with the metal bus (19B). With such a source bus structure in which the high conductivity metal layer and the transparent conductive layer are connected through the high melting point metal layer, the resistance value of the source bus (19) is small and remains stable for a long time.

Title: Depressed engraving processing method of enlarging character in printer
Inventor: LEE HYON-YONG
IPC: G06K15/00

Granted: 1993-09-23
Abstract: The method for making shade of enlarged characters  comprises the steps  of:  selecting  the  upper  position  of  the  original character and storing it to a buffer; storing the lower  character data adjacent to the upper position to  another  buffer;  shifting each of the character data by a degree respectively and storing it to a third buffer; and transfering the upper character  erased  in the another buffer to an image buffer and making the  shade.  Thus this invention can reduce the memory to a half of the conventional memory size and makes the shade process speedy.

Granted: 1994-06-11
Abstract: The feeding apparatus for photocopy machine has a intermediate roller contacting with a paper feeding roller that simplifies the driving mechanism. The link (17) is activated by activating the solenoid (20) to thrust upward the paper cassette (14) where a sheet of paper is pressed by the paper feeding roller (28) to transfer the paper to the intermediate roller (8) and returned to the original position by deactivating the solenoid (20).
