Patent CA-2097193-A1 (CA)
Inventor: KATAOKA HIROSHI
IPC: B29C33/38
Filed: 1992-09-25
Abstract: It has been conventionally considered difficult to adhere a mold metal and a polyimide, etc. whose coefficients of thermal expansion differ from each other by one figure and to retain the adhesion in injection molding, etc. involving severe heating-cooling cycles over several tens of thousands of times.  The greatest merit of injection molding resides in that a molded article of complicated shape can be obtained through one shot.  It has been demanded to obtain a mirror-smooth injection molded article with good molding surface reproduction without extending the mold-cooling time while retaining this merit.  The present invention provides a mold satisfying both of the durability and the demand.  The present invention relates to a mold for synthetic resin molding comprising a mold body made of a metal having a heat conductivity of not less than 0.05 cal/cmsec°C at room temperature having provided on the cavity wall thereof a polyimide layer, characterized in that said polyimide layer has a thickness of from 0.02 to 2 mm, has a heat conductivity of not more than 0.002 cal/cmsec°C, has a glass transition temperature of not less than 200°C, has been formed by coating a solution of a precursor of a linear high-molecular weight polyimide on the cavity wall followed by heating, has an elongation at break of not less than 10%, and has an adhesive strength of not less than 500 g/10 mm to the cavity wall.

Title: Method of and system for accessing distributed resources on isdn
Inventor: CUMMINGS Paul
IPC: H04L47/43
Filed: 1991-05-24
Abstract: An implementation of an ISDN router (100) enables computers interconnected to each other and to the ISDN to share resources by issuing operating system commands. One computer can access a storage disk or other resource of another computer distributed at any terminal location on the ISDN. Each disk on the Network has a unique name by which it is accessed. The configuration of the Network and number of computers distributed on it are transparent to each user. To improve bandwidth utilization of the ISDN line while sharing terminal resources, a B-channel allocation algorithm (180, 182, 184, 186) executed by routers (100) between the terminals and the ISDN line dynamically allocates bandwidth by monitoring (176) traffic at each destination queue and in response allocating (172) or deallocating (172) virtual B-channels (172, 174).  Bandwidth utilization is optimized by packaging data packets into trains that are transmitted to the destination when the train is completed and upon satisfaction of other conditions. Each train undergoes data compression by execution of a suitable compression algorithm.
