摘要:
The present invention relates to a resin composition for reflector plates containing 30 to 95% by weight of a semi-aromatic polyamide having the ratio of aromatic monomers to all the monomer components being 20% by mole or more, and 5 to 70% by weight of potassium titanate fiber and/or wollastonite. Additionally, the present invention relates to a resin composition for reflector plates used for an ultraviolet-ray generating source, comprising a thermoplastic resin and at least one inorganic compound selected from the group consisting of fibrous and flaky inorganic compounds capable of reflecting ultraviolet rays as well as visible light.

摘要:
This invention relates to a method or apparatus by which comparatively low-voltage electric wires and cables laid at power stations and other locations can be diagnosed for deterioration of their polymer-insulation in a non-destructive way. The method or apparatus comprises applying a torsional force to the electric wire or cable, detecting the resulting repulsion as a torque, and estimating the degree of deterioration of the polymer-insulation in the electric wire or cable on the basis of the detected value of torque.
摘要:
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.
摘要:
A biodegradable aliphatic polyester, such as polylactic acid, is mixed with a monomer having allyl and molded into a molding having the crosslinking degree of the biodegradable aliphatic polyester increased. Thereafter, the molding is exposed to ionizing radiation to thereby obtain a molding excelling in heat resistance. Triallyl isocyanurate or triallyl cyanurate is used as the monomer having allyl.
摘要:
By making different duty controls at the time of change in rotating speed and at the time of stable rotating speed, respectively, it is possible to realize the driving of a brushless motor 3 which enables smooth and rapid change of a rotating speed coping with a load.
摘要:
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.
