    摘要: It is an object of the present invention to provide a high frequency-capable printed wiring board material reduced in the dielectric loss tangent, weight, thickness and cost without compromising the workability, and provide electronic components using the same. The present invention provides a prepreg obtained by using a quartz glass cloth composed of low-density quartz glass fibers as a base material and impregnating the cloth with a thermosetting resin composition having a low dielectric loss tangent, and provides electronic components using a cured product of the prepreg as an insulating layer.

    摘要: It is an objective of this invention to obtain: a composition superior in processability, dielectric properties, heat resistance, and adhesiveness by controlling phase separation of a 1,2-polybutadiene resin composition without deterioration of dielectric properties exhibited in high-frequency regions; and a multilayer printed wiring board using the same.This invention relates to a polybutadiene resin composition, comprising: a crosslinking component (A) comprising repeating units represented by the following formula (1) and having a number average molecular weight of 1000 to 20000; a radical polymerization initiator (B), the one-minute half-life temperature of which is 80° C. to 140° C.; and a radical polymerization initiator (C), the one-minute half-life temperature of which is 170° C. to 230° C.; wherein 3 to 10 parts by weight of the component (B) and 5 to 15 parts by weight of the component (C) are contained relative to 100 parts by weight of the component (A). The invention also relates to a prepreg, a laminate, and a printed wiring board, which are produced using the same.

    摘要: A nuclear reactor vessel structure includes an inner peripheral tube-shaped steel plate, an outer peripheral tube-shaped steel plate, and an intermediate tube-shaped steel plate disposed between the inner and outer peripheral tube-shaped steel plates, and is configured to support a nuclear reactor vessel on the inner peripheral side of a tube-shaped structure with concrete placed between the steel plates. The nuclear reactor vessel structure includes a support having a tube-shaped plate disposed on the inner peripheral side of the intermediate tube-shaped steel plate, and an annular plate which protrudes to the inner peripheral side of the tube-shaped plate and to which a connection section is affixed. The support is affixed to the concrete, which is placed between the inner peripheral and the intermediate tube-shaped steel plates, by first bar members, and the support is also affixed to the inner peripheral tube-shaped steel plate by second bar members.
