摘要:
A phenol resin-impregnated sheet formed by impregnating a porous resin sheet with a phenol resin having a degree of cure of from 70% to 95% is arranged on and lamininated to the surface of a carbon fiber-reinforced thermosetting resin sheet. The thickness of the phenol resin impregnated sheet is between 0.01 mm and 1.0 mm. A very even, strong and water-proof wood reinforcing material is obtained. The wood reinforcing material is intergrated and cured on the surface of the wood material by the phenol resin-impregnated sheet to reinforce wood material (single board or bonded board) to form a reinforced wood material. The wood reinforcing material adheres suitably with the wood material and does not cause environmental contamination.

A golf club shaft is characterized in that: tenacity can be exhibited by the golf club shaft; power can be accumulated in the process of swinging the golf club; it is easy for a golfer to hit a ball with the golf club; it is possible for the golfer to get distance when he hits a ball; the direction of a ball, which has been hit with the golf club, can be stabilized; the layer member is not detached from the golf club shaft; and damage of the layer member is prevented, so that the mechanical strength and durability of the golf club can be enhanced. The golf club shaft comprises: a main body layer on which a first fiber-reinforced prepreg sheet, the reinforcement fiber of which is impregnated with synthetic resin, is rolled; and an adjustment layer on which a second fiber-reinforced prepreg sheet, the reinforcement fiber of which is impregnated with synthetic resin, is rolled, the adjustment layer being arranged inside the main body layer or in an intermediate portion of the main body layer, wherein the specific gravity of the second fiber-reinforced prepreg sheet is higher than that of the first fiber-reinforced prepreg sheet, the elasticity of the second fiber-reinforced prepreg sheet is lower than that of the first fiber-reinforced prepreg sheet, and a ratio of the volume of the adjustment layer to the volume of all layers is in a range from 10 to 90%.

According to the present invention, a resist resin having in its structure a specific bridged-bond-containing aliphatic ring, and a resist composition comprising the same are provided. By using this resist composition, a resist pattern excellent in both transparency against short-wavelength light and dry-etching resistance can be formed by alkali development with high resolution.

The present invention provides a pattern forming process. The process comprises the following steps. (1) A photosensitive material is prepared by coating a photosensitive composition onto the surface of a substrate. The photosensitive composition comprises the following components: (a) an acid generator which generates an acid when irradiated with actinic radiation, and (b) a compound containing carboxyl groups, which can decompose upon decarboxylation. (2) The photosensitive material is subjected to pattern-wise exposure to actinic radiation, thereby allowing the acid generator (a) to generate an acid in the exposed area. (3) The acid generated in the exposed area is neutralized with a basic compound (c). (4) The carboxyl groups in the carboxyl-group-containing compound (b) in the unexposed area are decarboxylated by applying conditions under which the basic compound (c) can catalyze decarboxylation. (5) The photosensitive material, and composition used in the above process are developed. The basic compound (c) can be introduced in advance into the photosensitive material prepared in step (1). By using such a pattern forming process or a photosensitive composition, a pattern can successfully be formed with high reproducibility without being affected by the environment.

An inner tube tube an outer surface of which is machined to define regerative coolant grooves for flowing a coolant to cool a combustor is split at a throat into upper and lower portions which in turn are fitted into an outer tube fabricated as a unitary structure. The upper and lower inner tube portions and the inner and outer tubes are integrally joined together.
