Title: Method for drying ceramic plate
Inventor: SHIN HAE-GUN
IPC: C04B33/30
Filed: 1987-05-08
Granted: 1989-10-30
Abstract: Improved efficiency in drying ceramic plate is ensured with the drying method.  The ceramic plate (2) formed by an extruder (1) is transported to a dryer (5) whose length is about 1.5m by the belt of roller.  After passing the dryer, the ceramic plates are dried by the roller drying device (6) whose length is about 1m.  Since the roller drying device comprises a number of heating rollers (6')(6")(6'") (6"") and press rollers (7)(8)(9)(10), the ceramic plates are dried and pressed unifomly without dawage.  The press rollers soften the ceramic plate, allowing the ceramic plate to be winded by winder (11) .

Abstract: An apparatus for compressing and decompressing digital data of a digital system using an ADRC(Adaptive Dynamic Range Coding) is disclosed. The apparatus comprises an encoder logic and a decoder logic. The encoder logic includes a maximum and minimum calculator(23) for calculating the maximum and the minimum values of a block, a subtracter for calculating the difference value between the maximum and the minimum value to provide a dynamic range, an adaptive encoder(25) for adaptively encoding the image data in the block according to the dynamic range, and a compressing converting logic(11). The decoder logic includes a decoding adaptive decoder(12) for receiving the output signal from the encoding logic.

Title: Surface treatment method and apparatus of metallic sheets
Inventor: KIM CHUNG-HO
IPC: C23C18/20
Filed: 1992-05-06
Granted: 1994-03-19
Abstract: The method comprising; degreasing to remove oil and alien substance; coating with photosensitizer; drying; exposing to light to develop; intermediately inspecting; etching the selected portion; and cutting at a regular length, is characterised by including removing the coated photosensitizer on both end sides of metal sheet and coating the both end sides with corrosion inhibitor before the intermediate inspection step. The method prevents an appearence of surface stains and cutting defects, and improves surface flatness.

Title: Image signal display apparatus
Inventor: CHOE SOK-KWON
IPC: H04N7/01
Filed: 1992-09-17
Granted: 1995-05-27
Abstract: The displaying apparatus converts a TV video signal of rate 4:3 in width and length into rate 16:9 on an existing color picture tube (CPT) of rate 4:3 in the screen width and length, then to display it, and also to be able to display as rate 16:9 on the CPT for a wide vision. The apparatus is composed of an image detector, a horizontal/vertical synchronizing separator, a horizontal/vertical deflection controller, starting place and end place counters, an image display area detector, an image processor, a switch and an amplifier.
