Title: Method of/and apparatus for manufacturing slide fastener coupling elements
Inventor: GASAI GAZUMI
IPC: B21F45/16
Filed: 1982-05-11
Granted: 1987-01-28
Abstract: The coupling elements are made from a rod of metal of an Yshaped cross section having a base, as a prospective coupling head, and a pair of diverging legs. As the rod is fed longitudinally stepwise, it is transversely sliced into coupling element blanks, one at a time, on the backward stroke of relative movement of a coacting cutting die and punch. At the end of the backward stroke of the cutting die and punch, a chamfering surface on the cutting punch is forced against the base of the rod to form a chamfered portion so that each sliced coupling element blank has the chamfered base. The chamfered base of each coupling element blank is then formed, by a coating forming die and punch into a final coupling head of one coupling element.

Title: On earth broadcasting and satellite broadcasting common receiver system
Inventor: LEE KI-RYONG
IPC: H04N5/46
Filed: 1989-11-14
Granted: 1992-03-27
Abstract: Satellite broadcast  signals  and  ground  broadcast  signals [which pass through an upcounter terminal (300)   are  selectively supplied to an LNB (100). A mixing terminal  (30)  which  receives the output signals of the LNB (100) also selectively  receives  an oscillating frequency from a local osciallating terminal (31)  for satellite broadcast and from a local oscillating terminal (39) for ground broadcast through a switch (SW2). Second IF signals of a BS tuner terminal (200)  are  selectively  supplied  through  another switch (SW3)  to  both  an  IF  tuner  terminal  (40)  for  ground broadcast  and  to  an  IF  tuner  terminal  (41)  for   satellite broadcast. With the system, the manufacturing cost case be  saved, and a miniaturization is rendered possible.
