Abstract: The status of the head/end apparatus including the modulator and the demodulator for broadcasting of cable television is detected and recorded for the system maintenance. The central control means generates the first information during the initializing step to send to the control module the needed information. The control module monitors the circumference temperature on scheduled interval and compares the sensed data with the first information to send the difference to the central control means with the error message only when the error condition is detected. The central control means displays the warning message on the display device, generates the warning sound, and dispatches the second information to deal with the error.

Title: Recording method and apparatus for electro-rheological fluid
Inventor: SONN SANG-SUK
IPC: B41J2/04
Filed: 1992-06-30
Granted: 1996-12-14
Abstract: The apparatus is designed to record electrostatic absorption using electro-rheological fluid. The apparatus includes : an injection head (10) having a nozzle (12) for injecting ink; a valve means for controlling flow of ink by applying a record potential (15) generating an electrical field to change viscosity of ink; and an acceleration means for conveying ink from the nozzle to a recording paper (16).

Title: Quinoline-imide polymer
Inventor: SONN TAE-WON
IPC: C08G73/12
Filed: 1992-07-18
Granted: 1996-07-23
Abstract: The process for making quinoline-imide polymer includes the steps of ;(a) making diamine by dissolving aromatic quinoline diamine in organic solvent such as N-NMP, N,N-DMAc, N,N-DMP or DMSO; (b) polymerizing by adding aromatic 4-basic oxide anhydride such as PMDA, BPDA, BTDA, ODPA, DSDA, 6FDA or NTDA to it; (c) obtaining polyquinoline amic acid film from it; (d) treaing it with heat. The viscosity of the polymer is above 0.1 dl/g when measuring at 30 deg.C with 0.5% sulfuric acid.

Title: Double deck type optical disk player
Inventor: KIM JUNG-TAE
IPC: G11B17/04
Filed: 1992-07-31
Granted: 1996-08-21
Abstract: The optical disk player is designed to perform the same function as an optical disk player of double deck type with an optical pick-up driving to the left and the right. The player contains : a conveyor motor (22) located on a deck frame (20) having a disk deck (14) and guide rods (26); a conveyor rack (28) protruded from a fixing chassis (30); a movable chassis (32) for guiding the deck frame (20); and a stopper (36) located under each disk tray (34, 34') for guiding the deck frame (20).

Title: Polysiloxanic stabilizers containing sterically hindered phenols groups and reactive groups
Inventor: PALLINI LUCIANO
IPC: C07F7/08
Filed: 1992-09-14
Granted: 1997-05-07
Abstract: Polymeric stabilizers with a polysiloxanic structure contain sterically hindered phenol groups and reactive groups capable of binding themselves to the polymeric structure to be stabilized. These polymeric stabilizers are particularly suitable for applications which require the non-extractability of additives due to solvents, fats or soaps.
