Patent KR-890002113-B1 (KR)
Title: Apparatus and method for manufacturing helical cores
Inventor: TALEF ALEXANDER
IPC: H02K1/16
Filed: 1982-09-17
Granted: 1989-06-20
Abstract: The device uses a rotating ring of pins to pull a prepunched continuous strip of material between two components which operate cooperatively to deform the strip by thinning one of its edges. The deforming force is held constant to avoid aberational deformations due to variations in strip thickness.  The continuous strip is pressed against the axial face of a mandrel.  A braking device provides tension on the strip as it progresses through its deformation, and a suitable dereeler provides a continuous supply of straight, prepunched strip material.  The apparatus provides for either two power driven deforming members or one power driven member and one idler.

Title: Compositions of refractory seramic mould
Inventor: KIM DONG-OK
IPC: B22C1/00
Filed: 1982-09-20
Granted: 1986-02-18
Abstract: The mold is improved by making the surface area per unit volume as small as possible, and by insuring that the refractory materilk used has a diamateral particle ratio which is beyond five to two. Here a maximum packing ratio was obtained by mixing large particles of 10 - 40 mesh (14-23%), middle particles of 100 - 140 mesh (21-24%) and small particles below 325 mesh (53-65%). As the refractory material, sands which were below 0.8% per 1000≰C in the coeffecient of linear expansion were used. An economical ceramic mold with enhanced its strength and minimized consumption of coking material has a high productivity.

Granted: 1988-09-07
Abstract: Video signals recovered from spiralling and circular information tracks or concentric circular information tracks on a record disc in a prescribed sequence of tracks.  The record disc is rotated and a selected track is played back by following the track with a read beam.  A predetermined number of tracks is then jumped across by incrementally moving the read beam radially of the disc during the vertical interval of the recovered video signal.  At least one frame of the recovered video signal is played after the jumping step.  The jumping step can now be alternately and repeatedly performed, similarly with playing at least one frame.

Title: High frequency heating apparatus
Inventor: MAHEHARA NAHOYHOSHI
IPC: H02M7/48
Filed: 1986-05-09
Granted: 1990-11-17
Abstract: Prim. current is supplied from the power supply (E) to the boost transformer (T) which is a leakage type transfer. The magnetron (M) connected to the transformer sec. winding (S) has a reverse blocking bad characteristic. The comparatively low coupling coefft. 0.6-0.8, between the prim. (P) and sec. (S) windings of the transformer provides a virtual leakage inductance in the flowpath for anode current (IA) to the magnetron. The by-pass capacitor (CP) which shuts the magnetron provides a path for current flow even when the magnetron is in reverse blocking state. This ensures that the transofrmer magnetisation is maintained and avoids the prodn. of voltage spikes by virtue of the sec. being virtually open-circuit.

The circuit includes a 2's  complement  adder  (1)  for  operating input data, an overflow compensator (2) for outputting positive or negative maximum value when operation in the 2's complement  adder generate overflow, an overflow direction flag (1a) for sending 1 o 0 to the overflow compensator when positive or  negative  overflow occurs in the 2's complement adder, and an overflow flag (1b)  for sending 1 to the overflow compensator when overflow occurs in  the 2's complement adder.

Abstract: This is new photosensitive resin composition including 2-  or 3- member macromer as polymer binder. Resin  composition  comprises 20- 60  wt.  pts  photopolymerization  compd.  including   terminal ethylene unsaturated  group,  30-70  wt.  pts  polymer  binder  of formula (I), (II), or (III), 0.1-10 wt. pts photo  initiator,  and 0.5-12 wt. pts additives. In formula, R is H or CH3. In (I)  ratio of 1:m:n is 0.45-0.85:0.05-0.30:0.15-0.55; mol.wt. is  1000-10000. In (II) 1:m:n is 0.5-0.7:0.1-0.3:0.1-0.3; Mw is  40000-60000.  And in (III) 1:m:n is 0.70-0.95:0.05-0.3:0;  Mw  is  1000-10000.  This composition has not viscosity. Its productivity is high.

Title: Method of fabricating dielectric layer for a capacitor
Inventor: JANG KUN-HA
IPC: H01L27/108
Filed: 1991-04-26
Granted: 1994-05-25
Abstract: Method of fabricating dielectric layer of capacitor in which a field oxide 2 is formed on a p-type silicon substrate 1, and a polysilicon 4 is deposited on the substrate to carry out photolithography, to form a pacitor dielectic layer 3 is disclosed, wherein a plate electrode is deposited and then a native oxide is formed using load-rock system, to form a silicon dielectric layer on the native oxide, and the silicon dielectric layer is thermal oxidised and a doped polysilicon is deposited, to form a dielectric layer, thereby reducing the power consumption and increasing the yield.
