Patent TW-390050-B (TW)
Title: Clip connector
Inventor: ISHIYAMA YOSHIAKI
IPC: H01R12/70
Filed: 1998-08-11
Granted: 2000-05-11
Abstract: A connectable plate (2) is mounted on an upper surface of a horizontal portion (the uniform thickness portion) (1b) of a housing (1). A plurality of contacts (3) mounted on the housing come into contact with a pattern of the connectable plate. A clip (4) has a U-shaped cross-sectional configuration. A spacing of a resilient forked portion of the contacts (an opening width) is larger than the thickness of the connectable plate but smaller than the sum of the thickness of the connectable plate and the thickness of the uniform thickness portion. When the clip is mounted to the connectable plate and the housing, an insulating coating portion (4d) of the clip slides onto the upper surface of the connectable plate, and a connector-housing-side end portion (4b) of the clip presses against an inclined protion (1a) of the housing. Thus, the opening width of the clip becomes larger, se that the connector-housing-side end portion slides smoothly onto the lower surface of the uniform thickness portion. As a result, the clip holds the connectable plate and the housing, and does not cause damage to either the connectable plate or to the clip connector.

Title: Continuous process for the production of segmented elastomer polyester copolymer
Inventor: HAGEN RAINER
IPC: C08G63/78
Filed: 1999-04-13
Granted: 2001-10-21
Abstract: The invention relates to a continuous process for the preparation of segmented elastomer polyester copolymers that shows greater flexibility with respect to the types and amounts of product to be produced than the known processes. The flexibility is achieved by splitting up a low-molecular PBT product stream from a continuous PBT process and partly using it as feed for the transesterification reaction with the polyalkyleneoxide glycol yielding soft segments to form a low-molecular segmented polyester copolymer, which is subsequently further condensed in the melt or optionally in the solid phase to form high-molecular segmented polyester copolymers. Even greater flexibility can be obtained by operating several parallel production lines for segmented polyester copolymer. Fluctuations in the types of copolyester product to be produced and the amounts thereof are accommodated predominantly in the polycondensation step of the PBT production.

Abstract: A memory module 10 is fitted with a ""cover and heat sink"" 5 having a U-shape in cross section in such a manner that the memory module 10 is inserted into a U-shaped deep recess of the ""cover and heat sink"" 5, and all packaged memory ICs 3 and the other components 2 mounted on each face of a printed circuit board 1 are covered by the ""cover and heat sink"" 5, with a silicone grease 6 being filled between the ""cover and heat sink"" 5 and the packaged memory ICs 3. The heat generated in each packaged memory IC 3 is conducted to the ""cover and heat sink"" 5 through the silicone grease 6, and the heat is radiated from the surface of the ""cover and heat sink"" 5 having a large surface area. In addition, since all the components 2 and 3 mounted on the printed circuit board 1 are covered with the ""cover and heat sink"" 5, the components 2 and 3 mounted on the printed circuit board 1 are protected from a mechanical shock. Furthermore, it is possible to discriminate whether or not the degree of the warping of the printed circuit board 1 exceeds a permissible limit. Because, if the warping of the printed circuit board exceeds a certain limit, the memory module cannot be inserted into the U-shaped deep recess of the ""cover and heat sink"" 5.
