Abstract:
A thin plate-shaped substrate 21 comprised of a monocrystal is provided with a piezoelectric element 24, and both ends of a movable piece 20 whose one surface is provided with a movable contact 25 are fixed and supported to a base 11. Then, by curving the movable piece 20 via the piezoelectric element 24, the movable contact 25 is brought in and out of contact with a pair of fixed contacts 38 and 39 that face the movable contact. With this arrangement, a subminiature micro-relay having a mechanical contact mechanism that has a small resistance in turning on the contact and the desired vibration resistance, frequency characteristic and insulating property can be obtained.

Specifically, disclosed is a resin composition comprising: 100 parts by weight of (a) a thermoplastic resin; 20 to 80 parts by weight of (b) a nonconductive fibrous inorganic filler having an average fiber diameter of not more than 15 μm; and 10 to 70 parts by weight of the total of (c1) a graphite and (c2) a graphite in which (c) graphite having an average particle diameter of 1 μm to 50 μm wherein each kind thereof has a different particle diameter; and at least one of differences in average particle diameter between two kinds thereof is not less than 5 μm.
Abstract:
This invention provides a polymer alloy comprising a polyphenylene sulfide resin and a polyphenylene ether resin. This polymer alloy can eliminate molding whitening which, upon molding, occurs on the surface of the molded product, can impart excellent surface appearance and flame retardance, and further can improve balance between heat resistance and toughness (impact strength) and mechanical strength. The resin composition comprises 45 to 99 parts by weight of a polyphenylene sulfide resin comprising (a) 0 to 96% by weight of a specific linear polyphenylene sulfide resin and (b) 100 to 4% by weight of a specific crosslinking-type polyphenylene sulfide resin. The resin composition further comprises (c) 55 to 1 part by weight of a polyphenylene ether resin. Further, the resin composition comprises (d) 1 to 20 parts by weight, based on 100 parts by weight in total of components (a) to (c), of a styrene copolymer and/or an ethylene copolymer containing any one functional group of glycidyl and oxazolyl groups.
