Abstract: PURPOSE:To provide a golf tee ground consisting of the artificial lawn which possesses the excellent tee insertion performance and outside appearance. CONSTITUTION:A golf tee ground consists of the artificial lawn mixed with sand, and as the sand filling the inside of the lawn part, is used the sand which has the max. resistance force of 10kg or less in the case where a container having an in side diameter of 90mm and a depth of 100mm is charged with sand and a round rod which is made of iron and has a diamete of 20mm is inserted by 50mm from the upper at a speed of 50mm, or the resin-worked sand may be used as the sand filling the lawn part.

Abstract: PURPOSE:To permit economical production of a low-loss plastic optical fiber by subjecting a monomer to be formed to a core component polymer to ultrafilter refining by using an ultrafilter membrane consisting of a specific polymer. CONSTITUTION:The monomer to be formed to the core component polymer is subjected to ultrafilter refining by using the ultrafilter membrane consisting of the polymer expressed by the formula. Any polymers which have >=50wt.% methyl methacrylate unit are usable for the core component polymer and a copolymer with methyl methacrylate in addition to a polymer consisting of the methyl methacrylate alone are also possible. Such copolymers are exemplified by a copolymer of methyl methacrylate and styrene, copolymer of methyl methacrylate and methacrylate such as bornyl methacrylate except methyl methacrylate. The filtration performance of the ultrafilter membrane consisting of the polymer expressed by the formula is preferably

Abstract: PURPOSE:To provide the titled fiber which has excellent light transmission performance at a near UV region wavelength and is less deteriorated in the light transmission performance even if rays of a near UV region wavelength are continuously transmitted and used by regulating the contents of the remaining methyl methacrylate and methyl methacrylate dimer to be incorporated into a core component polymer. CONSTITUTION:The remaining methyl methacrylate and the dimer of the methyl methacrylate incorporated in the core component polymer of this core and cladding type plastic optical fiber composed of the core and cladding satisfy formula I and the content of the remaining methyl methacrylate incorporated in the core component polymer is

Abstract: PURPOSE:To improve the durability of light transmissive performance for rays of wavelength in a near UV region by decreasing the light transmission loss of rays of 400nm wavelength to =80wt% polymethy methacrylate unit and a cladding component is formed of the polymer having the refractive index smaller by >=25% than the refractive index of the core component polymer. The light transmission loss of rays of 400nm wavelength is decreased to

Abstract: PURPOSE: To provide an artificial lawn and a ball game park which have a smooth feel and smooth touch to the foot, good durability, and is hard to set, and suitably used for tight sports and interior by improving the problems of the conventional artificial lawn such as hardness, a scatch and heat injury. CONSTITUTION: In case of an artificial lawn, pile is formed by a copolymer of nylon 6 and nylon 66. In case of a carpet, an artificial lawn formed by thin pile fabric of the above artificial lawn is laid on an indoor foundation bed or a floor. In the case of an artificial lawn stadium, an artificial lawn formed by thick pile fabric of the above artificial lawn is laid on a field foundation bed.
