Abstract: A tetrafluoroethylene resin molded article obtained by fusing PTFE by heating a tetrafluoroethylene resin by heating, and then executing a gradual cooling or a cooling including a holding at a temperature equal to or higher than 313° C. and lower than 321° C. for 10 minutes or longer, and having, when heated to 365° C., then cooled to 245° C. with a rate of ?1° C./min, and then heated to 365° C. with a rate of 10° C./min, a heat of fusion which, within a range from 296 to 343° C., is equal to or larger than 32 J/g and less than 47.8 J/g, a porous article obtained by expanding the molded article, and a composite article, a filter, an impact deformation absorber and a sealing material utilizing the molded article or the porous article.

Abstract: A method of preparing a gel from carboxymethyl cellulose alkali metal salt, which is an anionic cellulose derivative, by using acid or acid solution. To increase the strength and the elasticity of a gel, a water-insoluble metal compound or organic reinforcement is added when mixing. The obtained gel is one of environmentally friendly type gels because the raw material is derived from plant.

Abstract: A motorcycle having a vehicle body and a vehicle body frame. The vehicle body frame includes a head pipe; a pair of left and right tank rail portions including a widening portion having a width increasing in a vehicle width direction extending rearward of the vehicle from the head pipe, a parallel portion having a substantially fixed width, and a narrowing portion having a width decreasing the vehicle width direction, the widening portion, the parallel portion and the narrowing portion extend along left and right sides of the vehicle body of a motorcycle; and a pair of left and right rear arm bracket portions bending and extending from rear ends of the tank rail portions. The vehicle body frame has a front frame part and a rear frame part connected through a frame connecting surface substantially perpendicular to an axial direction of the parallel portion.

Abstract: A gel manufactured by irradiating ionizing radiation in the range of 5-1000 kGy to an obtained paste compound of a density of 10% by weight or more after adding water to carboxymethyl carrageenan and wherein each gram of dry gel obtained is capable of absorbing 20 grams or more of water. The ionizing radiation may be gamma rays, electron beams or X-rays.

Abstract: After adding water to the carboxymethyl carrageenan which is raw material and mixing them well, the ionizing radiation of more than fixed dose is irradiated to the obtained paste sample of fixed concentration. As a result, an excellent hydrogel in heat resistance which does not dissolve at 50° C. or more can be obtained. The manufactured gel can be used for many kinds of products. Because this gel has a biodegradation characteristic, it is possible to dispose by composting.
