IPC: C08L77/00
Filed: 1992-03-27
Abstract: A novel miscible blend of component polymers comprised of from about 5 weight percent to about 95 weight percent of a polybenzimidazole and from about 95 weight percent to about 5 weight percent of an aromatic polyamide aromatic polyamide-hydrazide or aromatic polyamide containing heterocyclic linkages. Miscibility of the component polymers of the blend is indicated by infrared, X-Ray and Differential Scanning Calorimetry analyses and scanning electron photomicrographs. In a film or molded article of a blend mostly comprised of a polybenzimidazole, it is preferred that the aromatic polyamide, aromatic polyamide-hydrazide or aromatic polyamide containing heterocyclic linkages be present in the blend in an amount sufficient to result in a blend with improved tensile properties compared to the polybenzimidazole and that is more thermally processable than the polybenzimidazole. In a blend mostly comprised of an aromatic polyamide, aromatic polyamide-hydrazide or aromatic polyamide containing heterocyclic linkages, it is preferred that the polybenzimidazole be present in the blend in an amount sufficient to result in a blend with increased thermal stability and nonflammability compared to the aromatic polyamide, aromatic polyamide-hydrazide or aromatic polyamide containing heterocyclic linkages. The blends, particularly in the form of films or molded articles, may be post-treated with heat or sulfonating agent in order to minizime their shrinkage when subsequently subjected to heat and in order to increase their resistance to solvrnts and acids.

Title: Bus arbitration circuit
Inventor: IWAMOTO HIROSHI
IPC: G06F13/362
Filed: 1990-05-11
Abstract: PURPOSE:To realize a bus arbitration circuit which fairly gives a bus using right acquiring opportunity to plural bus masters with simple hardware by utilizing the advantage of a fixed priority system by providing request storage circuits which store facts that the bus arbitration circuit has accepted bus requests from each bus master. CONSTITUTION:When one of bus masters 1-4 withdraws bus requests before a bus using permit is given to the bus master 1, 2, 3, or 4 after the bus master 1, 2, 3 or 4 sends the requests, a request storage circuit corresponding to the bus master is reset to '0'. This means that the acceptance of the bus request has been erased from a bus arbitration circuit 5 before a bus using right is given to the bus master and the circuit can make bus arbitration without trouble thereafter. In addition, a fair bus using right acquiring opportunity is given to each bus master, because, when the request storage circuit corresponding to one bus master 1, 2, 3, or 4 having lowest priority is set to '1', the bus arbitration circuit operates to prevent the request storage circuit corresponding to the other bus masters having higher priority from being set to '1'.

Title: Ink for marking pen
Inventor: KUROYANAGI KIYOSHI
IPC: C09D11/16
Filed: 1990-05-10
Abstract: PURPOSE:To obtain the tile ink the evaporation of which is suppressed on a pen nib and which provides a rapidly drying hand-written line on an ink- impermeable face by compounding a coloring agent, a resin, a volatile org. solvent and a specified nitrogen compd. CONSTITUTION:An ink for a marking pen is obtd. by compounding a coloring agent, a resin, a volatile org. solvent for the resin and a compd. selected from nitrogen compd. of formulas I, II and III (wherein R is a 12-30C alkyl; Y is a 1-4C alkylene; Z is H or OH). This ink is deposited on the surface of an opened pen nib of a marking pen as a result of the evaporation of the solvent to form a brittle thin film, which suppresses the evaporation of the solvent of the ink. As this thin film is easily destroyed by writing, it does not give any undesirable influence on ink flow-out. In addition, as the amt. of the ink on a hand-written line is extremely small and a relative surface area is large, the amt. of the evaporation suppressing agent therein is not enough for forming a continuous thin film of the whole surface of the hand-written line, so that the solvent could be evaporated to keep the rapid drying property of the hand- written line.
