Abstract: A resin composition comprises a copolymer (A) comprising ethylene as a major component produced with a single-site catalyst, and an ethylene-vinyl alcohol copolymer (B) having an ethylene content of 20-60 mol. % and a degree of hydrolysis of 95% or above, the resin composition satisfying the equation (1): 1/99≦{weight of (A)}/{weight of (B)}≦99/1  (1) A preferred resin composition comprises a copolymer (A) which has a density of 0.90-0.94 g/cm3 and the resin composition further comprises a carboxylic acid-modified polyolefin (C) and satisfies the equations (2) and (3): 60/40≦{weight of (A)}/{(weight of (B)}≦:99/1  (2) 0.1/99.9≦X≦:20/80  (3) wherein X={weight of (C)}/{total weight of (A) and (B)}. Another preferred resin composition comprises a copolymer (A) which has a density of 0.85-0.

Abstract: Electrical connective terminals for an input use and an output use of magneto-electric conversion element and a magnet are insert molded to a synthetic resin holder. At least one part of one end face of magnet is covered by one end of the synthetic resin holder 5. At an outer face of the covering part a circuit board 6 on which the magneto-electric converter element is mounted is installed. The covering part is arranged between the magnet and thr magneto-electric converter element. Thereby a predetermined gap is assured between the magnet and the magneto-electric converter element. When a distance formed between the magnet and the rotor of magnetic material is expressed as L, a distance formed between the magnet and a magnetic sensing part of the magneto-electric converter element is expressed as L1, then L1 equals to ¼L−¾L (L1=¼L−¾L) and the distance L1 is set with a range of 1.5 mm−4.5 mm.

Abstract: Provided is a polyvinyl alcohol having a triad isotacticity of at least 72% and an intrinsic viscosity of at least 0.1 dl/g (deciliter/gram) as determined by measurement of solution viscosity in acetone at 30.degree. C. of the polyvinyl acetate obtained by acetylation thereof. The polyvinyl alcohol of the present invention has a crystalline structure different from those of conventional isotactic polyvinyl alcohols and, as a result, exhibit excellent characteristics including high crystallinity and high melting point, as well as markedly high water resistance and thermal resistance. It has use as a high-strength fiber, high-water-resistant fiber, thermally resistant fiber and thermally resistant film.
