Title: Process for the manufacture of tubes on tube push bench apparatus
Inventor: OBEREM KARL
IPC: B21C1/26
Filed: 1981-06-09
Granted: 1985-10-19
Abstract: A small flange(4) is initially formed on the end of a tube to be rolled, the tube then being mounted on a mandrel rod(2) that is pushed though successive roll passes. The wall thickness of the blank(1) is reduced in at least three passes, the reduction in the first two passes being 40-60% less than in the third pass. The rod and blank are moved relatively slowly into the first pass(6) minimizing the motive force to be sustained by the flange, and movement is accelerated in the third pass. Waste at the flanged end of the blank is further reduced as part of the blank is rolled onto the rod in the reducing passes.

Granted: 1988-04-20
Abstract: The circuit maintains the rotating velocity of a load for induction motor constantly by digital control which uses the method of the pulse-width modulated AC chopper.  After the voltage source is applied, the driving circuit of relay (25) is operated by microprocessor (20) and the input source (AC) is applied to the induction motor through relay switch (RS).  Thence the large initial driving current prevents the transistor (TR1-TR4) of power conversion part (10) from being destroyed.  If the induction motor rotates in few seconds the relay switch is opened and the state signal detected in the velocity detector are applied to the microprocessor (20).

Title: Digital signal modulation circuit
Inventor: CHON BYONG-JIN
IPC: H03K5/00
Filed: 1990-09-13
Granted: 1993-05-22
Abstract: The circuit using a BPSK method comprises  a  digital  signal generator (10) for receiving  a  digital  clock  pulse  (CLK1)  to generate a predetermined digital signal, a first delay  unit  (20) for receiving the digital signal to phase-delay the digital signal according to a digital clock pulse (CLK2),  a  first  delay  array unit (30) for receiving a carrier  signal  to  delay  the  carrier signal, a first multiplexer (40)  for  receiving  the  array  (30) outputs to selectively output one of them by using  the  generator (10) output and the delay unit (20) output as  selection  signals, and a band pass filter  (50)  for  filtering  the  output  of  the multiplexer (40).

Abstract: 위치결정 장치는 캐리지(15,199)에 의해 안내된 테이블(101,213)을 포함하며, 상기 캐리지(15,199)가 베이스(3)에 대해 두 좌표 방향 (X,Y)으로 변위가능하며, 상기 테이블(101,213)이 단지 로렌쯔힘에 의해 동일 좌표 방향(X,Y)으로 캐리지(15,199)에 대해 변위가능하며, 반면 제3좌표 방향(Z)에서 테이블(101,213)의 위치는 정적 가스 베어링에 의해 결정된다. 
     이단 위치결정장치는 특히 광석판인쇄 장치로 사용하는데 적합하다.
