Title: Polyphenylene sulfide resin composition
Inventor: INOUE YOU
IPC: C08G75/02
Filed: 1989-07-10
Abstract: PURPOSE:To obtain a polyphenylene sulfide resin composition low in coloration and excellent in toughness by curing a polyphenylene sulfide having a specified melt-viscosity by heating in a nonoxidizing inert gas and mixing the cured sulfide with a glass fiber. CONSTITUTION:A polyphenylene sulfide resin composition comprising 100 pts.wt. product obtained by curing a polyphenylene sulfide(PPS) having a melt viscosity >=400P before curing (as measured under conditions of a temperature of 300 deg.C and a load of 10kg with a koka-type flow tester fitted with a die of a diameter of 0.5mm and a length of 2mm) by heating to about 200-270 deg.C in a nonoxidizing inert gas and 10-200 pts.wt. glass fiber having a weight loss <=0.7wt.% upon heating at 330 deg.C for 1hr. The reason for the curing an inert gas is presumably that excessive oxidative crosslinking occurring in curing in the air can be prevented in a nonoxidizing atmosphere and mainly the removal of valatiles centained in PPS, such as an oligomer, and an increase in the mol.wt. by a thioether exchange reaction, etc., proceed, so that a PPS composition low in coloration and excellent in toughness can be obtained.

Title: Data transmission method for communication repeater
Inventor: KATSUMATA HIDEKI
IPC: H04L12/46
Filed: 1995-07-12
Abstract: PROBLEM TO BE SOLVED: To avoid ordinary data from being stagnated and aborted in the communication repeater and to improve the efficiency of a LAN. SOLUTION: In the case of sending data from a LAN to other LAN via the communication repeater, the communication repeater stores data and records a storage time and compares the storage time of oldest priority data with that of oldest non-priority data (S2). Then the data are being sent in the order of priority. Simultaneously the number of times of the count run over by priority data are counted and recorded. Non-priority data are run over by priority data one after another and when the count reaches a prescribed value (m) (S9), the communication repeater revises the non-priority data into the priority data (S10). Thus, the revised data are sent from the communication repeater as oldest priority data with precedence over other non-priority data.
