Title: Surface protection layer producing method in magnetic record carrier
Inventor: LEE JONG-HWAN
IPC: G11B5/702
Filed: 1985-10-10
Granted: 1989-06-03
Abstract: Surface protection layer forming method in a magnetic record carrier is provided for easily controlling the thickness of a protection layer without using the melting substance.  To form the polymer protection layer on the magnetic layer of a base film, liquid phase polymer of 20≰ -300≰C is vaporized under the vacuum by an ultrasonic generator.  Vaporized polymer may be evaporated onto the magnetic surface of the base film kept at 0≰-120≰C to form the protection layer with the thickness of 50∦-2000∦.  The polymer substance is pref. photosynthetic acrylate copolymer.

Granted: 1990-05-04
Abstract: Optical recording carrier comprises a substrate; a layer (A) of an amorphous phase; and a Te metal layer (B) of a crystalline phase. Layer (A) is made of an optical recording material (I) contg. one of Te and TeOx (Ox2) as a main component, the amophous phase being changed to a crystalline phase by the irradiation of a laser beam, on layer (A), thereby recording information on (I). Layer (B) has a thickness of 50-300 angstroms and is provided between the substrate and layer (A) and is in direct contact with layer (A), such that layer (B) accelerates the phase change of (I) from the amorpholus phaes to the crystalline phase, to facilitate the recording of information on (I). ADVANTAGE-Sensitisation can be reduced, to shorten sensitisation time and improve C/N characteristics.

Inventor: TAKUCHI MASAO
IPC: G11C11/401
Filed: 1986-08-14
Granted: 1990-04-21
Abstract: The dynamic semiconductor memory device has a matrix arrangement of memory cells each designated by a row address, a column address, an error checking and correcting circuit.  The row address is received from an exterior in response to a row address strobe signal and the column address is received from the exterior in response to a column address strobe signal.  A refresh operation is performed when the column address strobe signal becomes low before the low address strobe signal.  Refresh operations are selectively performed with and without an error checking and correcting operation depending on timings of the row and column address strobe signals.

Granted: 1990-09-29
Abstract: Casting nozzle for use in continuous casting has a hollow chamber between an inner wall forming a pouring hole and an outer wall forming the nozzle proper. The upper part of the wall is of gas permeable material and the lower part is of impermeable mateiral, the periphery of the latter part containing reticulate small holes which communicate with the hollow chamber, opening at an outlet in the lower part of the nozzle. A blowing gas can be introduced into the chamber via a socket, passing through the permeable material and the small holes. The small holes are formed when organic filaments wound round the inside wall of the nozzle carbonise, volatilise or shrink on heating.

Title: Water supply control apparatus
Inventor: YOSHIDA TOKAO
IPC: H03K17/94
Filed: 1986-12-27
Granted: 1990-05-28
Abstract: A sensor responsive to one, at a time, of two driving signals detects whether thereis a user of a water flushing device at one of two periods, to produce a sensor signal selectively including a user- present signal and a user-absent signal of the one period. The sensor signal is used for controlling a water supply valve. The control in response to the user-absent signal issues a switching signal to generate the driving signal of the first period and in response to the user-present signal issues a second switching signal to generate the driving signal of the sencond period. A second control responsive to the water supply valve control signal operates the water supply valve.

Abstract: When the mis-align is generated in forming a  contact  region for contact between the storage electrode of the stacked capacitor and the source 3 region, the ion implantation  process,  with  the same conductive type as that of the source region, is carried out, to form the another source region under the bottom surface of  the contact region.

When  no   mis-align   is   generated,   the semiconductor memory device further  comprises  another  diffusion region formed below the source region.

Title: Audio output clipping method and circuit
Inventor: HWANG IN-UK
IPC: H03G7/04
Filed: 1991-07-19
Granted: 1994-04-30
Abstract: The circuit prevents the output signal clipping caused by high input signal level. The circuit includes a voltage divider (31) for attenuating output voltage of an audio amplifier, an A/D converter (32) for converting attenuated output voltage into digital signal, a clipping discriminator (33) for discriminating clipping state by checking output signal of the A/D converter, a D/A converter (34) for generating analog control signal according to the output signal of the clipping discriminator, and a gain adjuster (35) for adjusting the gain of the audio amplifier according to the analog control signal generated by the D/A converter.

Title: Brightness improvement system
Inventor: KIM SANG-RYOL
IPC: H04N9/77
Filed: 1992-01-15
Granted: 1995-01-28
Abstract: To improve the brightness signal for the good image in image processing, the interference of the color modulation signal with the brightness signal must be restricted. To do this, a system is suggested, where the interference is restricted through the proper processing with the signal based on the brightness signal separate from the image processor and the color modulation signal demodulated. The system is composed of a low path filter passing the low frequency component in the brightness signal, a high pass filter separating the high-frequency color modulation signal, a variable amplifier to remove the color modulation signal having the data at color boundary, and an adder mixing the output signals passing the above three elements .
