摘要:
Halogenated isobutylene-co-paramethylstyrene polymer, preferably brominated isobutylene-co-paramethylstyrene polymer (BIMS) and blends thereof, preferably blends of isobutylene based rubber, show improved heat resistance versus butyl inner tube compositions and retain the superior barrier properties of butyl inner tube compositions versus inner tube compositions with butyl/EP blends.

摘要:
Vulcanized rubber parts suitable to dampen vibrations generated by mechanical devices are disclosed. The parts are based on a cured composition comprising one or a mixture of a diolefin polymers, e.g., natural rubber, a halogenated copolymer of a C4 to C7 isomonoolefin, e.g., isobutylene, and a para-alkylstyrene, filler and a curing system. The vulcanized parts exhibit improved aging and high temperature resistance and reduced deterioration of dynamic properties after long term exposure to high temperatures.

A suspension system of a vehicle which judges the direction of a damping force of a shock absorber of damping force characteristic variable type, provided between the sprung member and the unsprung member, either oscillation-stimulating direction or oscillation-restraining direction with respect to vertical osciallation of the sprung member, and it also judges the size of the damping force of the shock absorber. The damping force characteristic of the shock absorber is set higher when it is larger than the predetermined value and it is set lower when it is less than the predertemined value. The predetermined value can be changed according to the road surface, oscillation-restraining energy becomes larger than the oscillation-stimulating energy thereby. Therefore, improvement of the comfortableness to ride in and running stability can be planned and also, noise and oscillation caused by unnecessary changes of the damping force characteristic of the shock absorber in a high oscillation frequency range due to road bumps can be reduced.
摘要:
A printed circuit board and video switcher board containing the circuit board including a first dielectric lamina having opposed surfaces and a first layer deposited on one of the surfaces which has of a plurality of first layer signal lines on one of the surfaces. A plurality of first ground areas of defined width are arranged between the first layer signal lines such that each of the first layer signal lines has one of the first ground areas on a side thereof so that none of the first layer signal lines is immediately adjacent to another first layer signal line. A second substantially uninterrupted layer on the other surface of the first lamina forming a second ground area which is substantially coextensive with the other surface. At least two holes extend through the first lamina between the first and second ground areas and each of the holes has openings at the first ground areas and at the second ground area. A conductive member in the holes electrically connects the first and second ground areas for shielding the first layer signal lines from each other, and the separation between the holes is less than the width of the first ground areas.
