Patent KR-860000895-B1 (KR)
Title: Producing method of human growth hormaone
Inventor: SUKUMODO KANAME
IPC: A61K38/27
Filed: 1981-07-23
Granted: 1986-07-16
Abstract: Prodn. of human growth hormone(hGH) comprises (a) growing a cell capable of producing hGH in any warm-blooded animal other than a human or in a device, esp., a diffusion chamber which supplies them with the nutrient body fluid directly from warmblooded animals. (b) The grown cells are then treated with an hGH inducer. Suitable host animals include hens, pigeons, dogs, cats, cows, etc. Pref. cells which are recommended for use include intact acidophiles from anterior hypophysis, viral trasformed or X-irradiated cells, human acidophils adenomas or lymphoblastic luekemia hybridomas. Inducers are amino acids and metabolites such as serotonin and polypeptides. A multiplication factor(for the transplanted cells) of 10 - 100 million can be achieved in 1 - 20 weeks.

Title: Nuclear reactor with partitioning by bracing rods and plateo
Inventor: VARDEAU JEAN-JACQUES
IPC: G21C5/10
Filed: 1982-03-13
Granted: 1989-04-28
Abstract: The core consists of numerous fuel assemblies (5) located inside a cylindrical sheath (8).  The core is placed in a reactor vessel, and a prim. coolant flows up the bore of sheath.  Between the peripheral assemblies (22) and the inside wall of the sheath is a space which contains a vertical row of horizontal spacer plates (18) fixed to the inside wall of the sheath.  Each spacer plate contains several holes in which vertical rods can slide. The rods form several rows which are close together and near the peripheral assemblies, so the rods form partitions controlling the flow of the prim. coolant near the inside wall of the sheath.

Title: Chrominance signal processor
Inventor: THOMAS YOST D
IPC: H04N9/64
Filed: 1982-04-09
Granted: 1988-06-30
Abstract: The circuit is used in a colour television receiver employing a comb filter.  The comb filter e.g. one using CCD's responds to switching signals for providing separate outputs from which the luminance and chrominance television signal components are derived.  The translating circuit includes two cascaded, bandpass filters.  The first filter receives comb filter output signals including desired chrominance signals and undesired signal components.  The circuit prevents unwanted high frequency components, partic. those associated with the comb filter switching signals, from reaching the colour demodulators of the receiver.

Title: Process for bonding copper or coppoer-chromium alloy to ceramics
Inventor: KASHIWAKI YOSHIYUKI
IPC: B23K20/00
Filed: 1983-02-16
Granted: 1987-04-09
Abstract: This invention relates to the bonding method of copper or copper- chromium alloy and ceramics. A chromium film, approximately 1micron m thick, is formed at the bonding side of alumina ceramics by continuous vacuum evaporation method, and it is converted to the chromium oxide film by continuous heating. The copper is attached to the chromium oxide film, and the assembly is continuously heated in an inert gas atmosphere. The assembly is cooled in the vacuum furnace, and bonded strongly because the thermal stress is absorbed by the plastic deformation of copper.

Abstract: The method charges the call fee with  self-equipped  ordinary apparatus of  the  PBX.  The  information  about  the  time,  data subscriber code, dialed number, or  kind  of  used  line  etc.  is recorded on the CPU memory during the call.  When  completing  the call, the CPU checks the dialed number whether it was a  local  or international one, and determines which code table  is  referenced according to the checking result. When there is an index  code  in the dialed digital code the unit time and fee  rate  are  selected from the code table as well as the basic time and rate. The actual fee is calculated with the selected data and  accumulated  on  the subscriber memory. The stored contents can be printed out  through an I/O interface after converting the data to the ASCLL code.

Abstract: 방사선-중합성 혼합물 및 감광성 내식막 마스크의 제조방법 
     본원에는 중합성 화합물, 메트아크릴산, 메트아크릴산 에스테르 및 스티렌(여기에서 스티렌은 40 내지 65중량%이다) 단위를 함유하는 중합체 결합제, 실릭산 또는 실리케이트 염기를 갖는 미분된 무기 염료, 광중합 개시제, 분자내에 적어도 두개의 에폭시 그룹을 함유하는 화합물 및 에폭시 그룹에 대한 열 경화제를 함유하는 방사선-중합성 혼합물에 대해 기술되어 있다. 특히, 이 혼합물은 땜납 내식막 마스크 제조에 적합하며 80 내지 150℃에서 가열시킴으로써 상 및 현상액에 노출시킨 후 경화시켜 납땜 조건하에서 내식성을 갖는 스텐실을 형성할 수 있다.
