Abstract: A polyethylene resin composition for spacer for optical fiber cable provided with a plurality of channels spirally formed on the periphery surface thereof for receiving the optical fiber comprising polyethylene resin having a melt index of more than or equal to 0.01 g/10 min to less than 0.30 g/10 min, a density of 0.941 to 0.955 g/cm.sup.3 and a flow ratio (HLMI/MLMI) in accordance with JIS K7210 of 20 to 55, and optionally fluorine elastomer.

Abstract: A carrier for electrostatic latent image developing for use in methods of developing an electrostatic latent image formed on the surface of a latent image-bearing member by transporting a developer comprising a toner and a carrier via the rotation of a developing sleeve having a built in stationary magnet roller, the carrier for electrostatic latent image developing including magnetic powder dispersed in a binder resin and having a saturation magnetization of about 50 to about 80 emu/g, residual magnetization of about 3 to about 10 emu/g, and coercive force of about 20 to about 50 oersted.

Abstract: The present invention provide a carrier for development of electrostatic latent images, comprising magnetic powder dispersed in binder resin, the carrier having a mean particle size in a range of 30 to 80 .mu.m and satisfying the following relational expression:(x).sup.2 /.phi..sup.2 .gtoreq.9.0wherein x represents mean particle size of the carrier and .phi..sup.2 represents variance of particle size distribution.The carrier of the present invention is superior in chargeability and fluidity and free from occurrence of carrier adhesion even when used in combination with small particle size toner and which can form excellent copy images.

Abstract: A thermal transfer recording medium comprising a support and a heat-fusible ink layer, coated on the support, which comprises a colorant and a binder. The binder comprises a polyurethane having bisphenol units or a polyether having bisphenol units and an hydroxyl group at the terminals. The thermal transfer recording medium provides a transferred image with a high quality regardless of the transferring paper.

Abstract: The present invention relates to a telescopic drinking straw or double sucking tube in which a synthetic resin tube section having a smaller diameter is inserted into a synthetic resin tube section having a larger diameter. In the sucking tube, a flange which is in tight contact with the inner surface of the larger tube section is formed on the smaller tube section, while a convex portion supporting the smaller tube section is formed on the inside of the larger tube section. Both the larger and smaller tube sections are produced from materials having different compositions from one another, so that leakage of fluid from a joint portion of the larger and smaller tube sections as well as shaky motion of the smaller tube section are prevented by these arrangements.

Abstract: A product comprising a soft elastic base material and an electroconductive film formed on the base material by applying a coating composition to the base material and fixing the composition by an insolubilizing treatment such as irradiation with light, heating or the like, the composition comprising an aqueous solution of polyvinyl alcohol, a fine powder of electroconductive material dispersed therein and an insolubilizing agent for insolubilizing the polyvinyl alcohol by the insolubilizing treatment. The composition may contain a softener to impart softness to the electroconductive film. The soft elastic base material is made of a spongy foamed material and fixed to the peripheral surface of a base roller.
