Title: Recording reservation method with screen guidance
Inventor: RYU KEUN-BAE
IPC: H04N5/445
Filed: 1986-11-07
Granted: 1991-10-15
Abstract: A method is used for easily reservating the video  record  by displaying the reservation information on a television  screen.  A microprocessor  recognizes  the  reservation  key  input  or   the function key input of a remote controller, and provides the signal to display the reservation record  information  to  the  on-screen controller. The on-screen controller produces the character signal to display the reservation  record  information.  A  video  signal mixer mixes the character signal for  displaying  the  reservation record information and the video signal.

Title: Digital analog double use recording & playing system
Inventor: YANG TAE-SOK
IPC: G11B20/10

Abstract: A system for a video cassette recorder is capable of recording/reproducing analog video and audio signals as well as digital video and audio signals for a HDTV. The revolution of a head drum may be determined different from each other depending on the selected mode, i.e., digital or analog signal recording/ reproducing mode, and thus thd digital signal having a different recording bandwidth from the analog signal can be recorded on and reproduced from a conventional analog tape.

Title: Process for the preparation of iron hydroxide by oxidation-reduction electric potential
Inventor: SON JIN-KUN
IPC: C01G49/02
Filed: 1992-12-30
Granted: 1995-10-24
Abstract: Preparation of iron hydroxide (gamma-FeOOH) comprises (A) adjusting concentrations of reactants, FeCl2 and NaOH, by keeping the initial voltage at -400˜-800 mV ; (B) producing iron oxide seed by adjusting agitation speed and air supply until the electric potential reaches +50˜+20 mV ; and (C) growing the iron oxide seed at the oxidation-reduction potential of -100˜+100 mV by adjusting agitation speed, air supply and alkali feeding rate. A couple of electrodes, a calomel electrode as reference electrode and a platinum electrode as indication electrode, to measure the oxidation-reduction potential are installed in the reaction vessel.
