An adapter (101) connected between a host computer (104) and disk storage devices (107, 108), provides interfaces for connecting to the host computer and the disk storage devices which have the same interface design. The adapter itself includes control means (204, 207, 209, 210, 211) for building a redundant disk storage system. Moreover, the adapter itself includes means for detecting and indicating a failed disk storage device, means for replacing the failed disk storage device, and means for rebuilding a redundant disk storage system after the replacement of disk storage devices. A command is configured so that the host computer can have access to each of the disk storage devices for maintenance purpose. <IMAGE>

Title: Chrominance signal control circuit of video signal
Inventor: KIM SUNG-JOON
IPC: H04N9/64
Filed: 1993-07-21
Granted: 1997-03-25
Abstract: A circuit for controlling a color signal of an image signal is disclosed. The circuit comprises a color signal processing unit(10) for receiving an image signal, dividing the received image signal to a color signal and a luminance signal, and providing RGB signals through a matrix; a switching block(20) for switching the RGB signals from the color singal processing unit(10) to provide the switched signal to a CRT; and a switching unit connected between the color signal processing unit(10) and the switching block(20), controlling an on/off operation of the RGB signals according to a control signal provided from a microcomputer(30).

Title: Apparatus for displaying screen of tv
Inventor: KIM HAN JIN
IPC: H04N5/45
Filed: 1993-07-22
Granted: 2001-05-02
Abstract: PURPOSE: An apparatus for displaying a TV screen is provided to offer OSD service through the screen of TV having PIP and POP functions and selectively display a letter broadcast. CONSTITUTION: The first and second tuners(102,103) tune composite video signals received through an antenna, respectively. A synchronous signal generator(104) generates a synchronous signal according to a control signal generated by a microcomputer. An OSD processor(105) generates and processes an OSD signal on the basis of the synchronous signal. A signal mixer(106) for mixing the synchronous signal with the OSD signal to generate an OSD video signal. The first signal selector(107) selects one of the tuned video signals. The second signal selector(108) selects one of the video signal tuned by the first tuner and the OSD video signal. A main screen signal processor(109) processes the signal selected by the second signal selector to display on a main screen. A letter broadcast decoder(110) decodes a letter broadcasting signal in the signal selected by the second signal selector. A letter broadcast output selector(111) transmits the decoded letter broadcasting signal. The third signal selector(112) selects one of the signal tuned by the second tuner, OSD video signal and the transmitted letter broadcasting signal. A sub-screen signal processor(113) processes the signal selected by the third signal selector to display on a sub-screen. A display(114) device displays the signal processed by the main screen signal processor and the letter broadcasting signal on the main screen, and displays the signal processed by the sub-screen signal processor on the sub-screen.

Title: Process for the production of high colouring carbon black
Inventor: BANG JONG-HAN
IPC: C09C1/48
Filed: 1993-08-24
Granted: 1996-09-16
Abstract: The carbon black that shows high colouring property has a nitrogen adsorption(BET) specific surface area (N2SA) of 190 to 210 m2 /g, a dibutyl phthalate absorption number of 50 to 70 ml/100 g, an extraction from the nitrogen adsorption(BET) specific surface area(N2SA) and iodine adsorption number of 8.5 to 10.5. The carbon black can be used for a black pigment in case of dispersing into a plastic, paint or ink.

Title: Insulating film forming method of semiconductor device and apparatus therefor
Inventor: PARK INN-SUN
IPC: C23C16/44
Filed: 1993-08-31
Granted: 1997-05-02
Abstract: A forming method of an insulating layer of semiconductor devices is provided to simplify processes, perform at low temperature and improve an aspect ratio. The method comprises the steps of: forming a conductive pattern(53) on a lower insulating layer(52); performing a plasma treatment at the exposed surface of the conductive pattern(53) and the lower insulating layer(52) in order to be different the polarity of the surface each other; and depositing an insulating layer(54) having a different depositing rate according to the surface polarity on the resultant structure, thereby easily forming flattened insulating layer.
