Patent KR-860001971-B1 (KR)
Title: Apparatus and method for vulcanizing a tire
Inventor: SARUMARU KAZUMASA
IPC: B29D30/06
Filed: 1982-03-25
Granted: 1986-11-07
Abstract: A bagless tire vulcaniser and moulder comprises a pair of cooperating mould halves defining a carcass receiving cavity. Located within the cavity is a device for pressing the beads of the tire firmly against the walls of the cavity to prevent leakage of vulcanising medium which is supplied into the interior of the tire. The device is radially expandable against the bias of springs to a position in which pressing members can engage the beads of the tire as the mould is closed. After vulcanising and moulding, the pressing device radially contracts under the influence of the spring to an out-of- the-way position not interfering with tire removal.

Title: Directionally imaged sheeting
Inventor: HOCKERT ERIC N
IPC: G09F13/16
Filed: 1984-02-07
Granted: 1990-08-09
Abstract: A monolayer of microsphere lenses are embedded in a transparent layer e.g.polymeric sheet. A reflective layer e.g. Al or Ag is deposited on the profiled back surface of the sheet so that each microlens has a concentric area of reflective layer. The reflective layer has small axial openings made by laser beam and giving an image when viewed from the front of the sheet along line under ambient or transmitted light or retroreflective conditions. A coloured layer behind the reflective layer can be provided to give coloured images by impregnation of the spacing layer of the sheet. Instead of holes the image can be formed by recesses or other deformities. Authenticating overlay film on documents or drivers' licences, coloured and black and white images are possible.

Title: Method for reduction of sinter
Inventor: JO YONG-HWAN
IPC: C22B1/16
Filed: 1984-02-17
Granted: 1987-12-28
Abstract: The method presents an optimum composition of sintered ore with a thickness of 500-520 mm which comprises magnetite in 14-16 wt.%, slag 19.8-20.0 wt.%, TiO2 0.2 wt.%, quicklime 0.36-0.8 wt.% and the balance of hematite and unavoidable impurities.  The increased amount of slag restrains the diffusion of cracks and oxygen to stabilize the formation of magnetite, and TiO2 is limited to 0.2 wt.% at maximum to prevent the deterioration of reduction degradation index.

Abstract: The decoder using a DSP chip to simplify thit design  detects the start bar  and  end  bar  to  operate  the  DSP  so  that  the mulfunction caused by the noise signal is prevented.  The  decoder comprises the first and second counters (2,3) counting  the  white and black bar codes generated from a 40 MHz clock  generator  (1), the first and second latches (4,5) latching  the  counted  numbers temporarily and providing to the DSP, a D flip-flop (6)  detecting the start (STB) and end (ENB) bars  and  providing  the  detection signal to the DSP, a DSP (7) counting how many white and black bar codes are  entered  when  the  compaing  them  to  self  contained standard bar code length, RAM (8) and ROM  (9)  communicating  the data to the DSP, and the third latch  (11)  latching  the  counted number by the DSP and providing them to a host computer (10).

Abstract: 빠른 개시 시간을 가지며 다른 유사한 회로에 직렬로 접속되거나 차동 증폭기와 종속 접속될 수 있는 직류 차단 증폭기. 
     상기 회로는 배터리 절약기술을 채용하는 디지털 페이징 수신기에서 사용하기에 적합하다. 
     상기 회로는 제1 및 제2의 차동 증폭기(40,42 및 44, 46)와 제1 및 제2의 평형 입력 라인(52, 56)을 포함하여, 상기 제1의 입력 라인(52)은 동작시 상기 제1의 입력 라인(52)을 통해 인가되는 교류 신호를 증폭하는 제1의 차동 증폭기에 접속되고, 상기 제2의 입력 라인은 동작시 상기 제2의 입력 라인(56)을 통해 인가되는 교류신호를 증폭하는 제2의 차동 증폭기(44,46)에 접속된다. 상기 제1 및 제2의 차동 증폭기(40,42 및 44, 46)의 출력은 상기 제1 및 제2의 평형 입력 라인 각각의 직류 상태와 무관한 증폭된 신호를 생성하기 위해 결합된다.
