Patent KR-900005790-B1 (KR)
Title: Pulse generator
Inventor: ONO TADAHIRO
IPC: H03M1/00
Filed: 1985-06-12
Granted: 1990-08-11
Abstract: The pulse generator includes a transducer, e.g. a resolver coupled to a driven body, for converting mechanical motion to a phase-modulated signal. A generator supplies an excitation signal as a carrier of the phase-modulated signal to the transducer. A counter receives clock pulses from a generator to form a content of count representing a time interval by which the logically high or low output from a waveform shaping circuit, for the phasemodulated signal, is longer or shorter than the corresponding period of the excitation signal. A gate circuit allows the count pulses to enter the counter until the counter, having contents of count corresponding to the time interval, is initalised. An output sate circuit issues the counted pulses as a serial train.

Title: Process for producing methoxyiminoacetamide compounds and intermediates
Inventor: TAKASE AKIRA
IPC: C07C249/04
Filed: 1991-07-25
Granted: 1999-06-15
Abstract: A process for producing a E-isomer of the formula:wherein X is hydrogen, C<sub>1</sub>-C<sub>6</sub> alkyl, C<sub>1</sub>-C<sub>6</sub> alkoxy or halogen; A is -CONHCH<sub>3</sub> or -COOR; and R is C<sub>1</sub>-C<sub>6</sub> alkyl comprises reacting a Z-isomer of the formula [VI]:wherein X, A and R are as defined above, with an acid in a C<sub>1</sub>-C<sub>6</sub> alcohol.

Title: Manufacturing method of weft elasticity woven
Inventor: KIM NAM-JUN
IPC: D03D15/567
Filed: 1991-08-27
Granted: 1993-08-31
Abstract: weaving the fabric, using the weft yarn of thermoplastic synthetic filament  false-twisted  crimped  yarn, whose stretchability is 28-45 %, stretch recovery rate is 75-99 %, shrinkage rate in hot-water is 35-55 % and  the  twist  number  is 95-215 ea./m, and the warp yarn so that the weft  number  (n)  per inch of the weft yarns is 560 < n root D2 < 990 (where D2  is  the denier of the weft yarn) and the warp yarn number (N) per inch  of the reed is 78 < N x root D1 < 1610 (where D1 is the denier of the warp yarn); heat-treating; and finally shrinking the weft yarn  so that the condition after F-setting is 26.2 < N1 x root D3  -  N  x root D1 / N x root D1 x 100 < 77.9 (where N1 is  the  weft  number per inch after F-setting, D3 is the denier of the warp yarn  after F- setting).
Patent KR-940004480-B1 (KR)
Title: Pick-up correction device for digital recording apparatus
Inventor: YUN JONG-KYONG
IPC: G11B5/09
Filed: 1991-11-12
Granted: 1994-05-25
Abstract: The amplitude of start and end part of a pick-up signal is raised to normal pick-up signal level so that the effective period of a pick-up signal is enlarged. The apparatus includes a level compensator for changing level of pick-up signal, a data decoder for reproducing data from pick-up signal, an envelope level detector for detecting envelope level of the pick-up signal, an envelope level controller for controlling envelope level of pick-up signal.
Patent KR-970008860-B1 (KR)
Title: Cutter of waste yarn for twisting machine
Inventor: LEE SANG-JIN
IPC: D01H9/16
Filed: 1991-11-20
Granted: 1997-05-30
Abstract: To be able to enhance the workability of a twister and to reduce human resources at the same time as generation of various accidents caused by a manual work, an operation controlling means comprises air cylinders 1,2 for moving an electric heating type cutting knife(10) and an absorbing nozzle(20). And a timer T1 for controlling the operation of this air cylinders 1, 2, a solenoid valve 1, also a timer T2 for operating the above absorbing nozzle(20) are included in this twister. In addition a solenoid valve 2 and a timer T3 which stops the operation of the electric heating type cutting knife and the absorbing nozzle, at the same time as returning the components to their original position, and which controls the solenoid valve 1 are contained therein.

Title: Polymerization process and catalyst
Inventor: JOB ROBERT C
IPC: C08F10/00
Filed: 1990-04-19
Granted: 1994-05-04
Abstract: A process and a catalyst for the production of elastomeric primarily syndiotactic polypropylene characterized by short average block lengths wherein propylene is polymerized in the presence of the catalyst which comprises the reaction product of a magnesium alkoxide and a tetravalent titanium halide which takes place in the presence of an electron donor, an organoaluminum compound, and a selectivity control agent which is an effectively hindered heterocyclic aromatic nitrogen compound wherein the hindrance is not provided by a Cl- or methoxy group.
