Abstract: The method and machine is shown for the production of rolls or logs of web material. The web material is fed through a nip (5) formed between two winding rollers (1, 3) and wound up around a core to form a roll or log (R) within a winding space defined by said two winding rollers and by a third roller. At the end of the winding of a log, the third roller (7) is temporarily accelerated to locally increase the speed of the web and to put the web material in tension between the third roller and one of said winding rollers. The tearing of the web material takes place because at that moment the incoming web is pinched between a new core and the one winding roller on which the material is driven out. <IMAGE>

Patent KR-960001941-B1 (KR)
Title: Plate display device
Inventor: PARK KYUNG-RYONG
IPC: C03C17/36
Filed: 1992-11-10
Granted: 1996-02-08
Abstract: The device comprises a matrix of selection lines and data lines, each micro light valve comprising a data electrode connected to a data line through a via, a selection electrode connected to a selection line, a common electrode between the selection and data electrodes, a frame and a shifting element which can be moved by drive signals to be applied to the data and selection electrodes so as to pass or shut off a light beam. Drivers are connected to the selection and data lines for supplying selection and data signals to the light valves. Micro-mechanical display device has a large area and superior performance.

Title: Single chip optoelectronic integrated circuit and manufacturing method thereof
Inventor: OH KWANG-RYONG
IPC: H01L27/146
Filed: 1992-12-15
Granted: 1996-11-07
Abstract: recess etching of a semi-insulating substrate(1) to the height of a photo detector, and growing an n-channel layer(2), an etching barrier layer(3), a p-InGaAs layer(4), an undoped InP layer(5), an undoped absorbing layer(6) and a n-InP layer(7) in sequence; etching the n-InP layer(7) and the absorbing layer(6) and the InP layer(5) selectively except the region of the photo detector; selective etching to separate the photo detector and a transistor electrically; forming p-electrodes(8,9) of the photo detector and the transistor; forming a gate by etching the p-InGaAs layer(4') and the p-InP layer(3') selectively using the p-electrode(9) as a mask; forming two electrodes(10a,10b) of the photo detector and a source electrode(11a) and a drain electrode(11b) of the transistor; etching a polyimide(12) for the contact of a second wiring metal; and connecting the photo detector with the transistor electrically by depositing a wiring metal(13).

Title: Co-producing mehtod of 1,1-dichloro-1-fluoroethane and 1-chloro-1,1-difluoro ethane
Inventor: NAM KYONG-HUI
IPC: C07C17/10
Filed: 1992-12-16
Granted: 1995-09-28
Abstract: 1,1-Dichloro-1-fluoroethane(HCFC-141b) and 1-chloro-1,1-difluoroethane(HCFC-142b) are simultaneously prepared by reacting 1.3-2.3 mole ratio of fluoric acid anhydride with 1,1,1-trichloroethane, at 30-60 deg.C and 0-1kg/cm2G in the prsence of antimone pentachloride(SbCl5) as a catalyst. The ratio of the obtd. HCFC 141b/HCFC-142B is controlled at 40/60-10/90 wt.%. by the mole ratio of fluoric acid anhydride with 1,1,1-trichloroethane, reacting under adjustmorl adjustment of temp., pressure and concentration of the catalyst. The obtd. HCFC-141b and HCFC-142b is useful as a foaming agent for urethane, cleaning agent, refrigerant, and dispersing agent for aerosol. The obtd. HCFC-141b and HCFC-142b each can be a substitute for CFC.

Title: Method for manufacturing a cell capacitor in dram
Inventor: LEE BONG-JAE
IPC: H01L27/10
Filed: 1992-12-26
Granted: 1996-04-26
Abstract: The method includes the steps of forming a gate electrode(23), source and drain region(24) on an active region of a semiconductor substrate(1), forming a first silicon oxide layer(25a) on the substrate, forming a bit line polysilicon layer, second silicon oxide layer(25b), silicon nitride layer(27), node polysilicon layer(28c) and third silicon oxide layer(25c) in series, opening contact holes to expose the source and drain, forming a node polysilicon layer(28), and oxide sidewalls(25d) on the sides of the node polysilicon layer(28), forming a pillar polysilicon layer(29) on the oxide side walls(25d) and node polysilicon layer(28) and removing the pillar polysilicon layer(29) placed on the node polysilicon layer(28) and oxide layer(25d) and silicon layer(29,28c) placed therebelow, to form a capacitor node electrode.
