摘要:
The present invention is to provide a base material for a laminate having a high strength, reduced thickness, and light weight. In the present invention, a base material is prepared by incorporating a thermosetting resin binder into a non-woven fabric of para-aramid fibers prepared by a wet type paper making, and then heating a plurality of the resultant non-woven fabric sheets under pressure. The non-woven fabric sheet comprises 95 to 70 mass % of the para-aramid fibers and 5 to 30 mass % of the thermosetting resin binder.

A polished-piece holder is provided that does not easily stick or adsorb to a polishing pad of a polishing apparatus and reduces occurrences of production line troubles and therefore the number of failed polished pieces. A single sheet of a thermosetting resin impregnated fiber substrate or a laminated sheet formed by laminating a plurality of sheets of the thermosetting resin impregnated fiber substrate is formed under heat and pressure into a plate. The thermosetting resin impregnated fiber plate is then processed to form a polished-piece holder for holding pieces to be polished. The evaluation portion has a certain length in a direction of the average line. The thermosetting resin impregnated fiber plate has a surface roughness with a maximum wave height Ry of 10 &mgr;m or greater over an almost entire area of the surface layer. The maximum wave height Ry is determined in an evaluation portion of a wave curve by summing a height Rp of a highest crest and a depth Rv of a deepest trough from an average line of the wave curve. The wave curve is taken from a cross-sectional curve obtained by the surface roughness measuring device.

A braking member includes a body member and first and second interposed members. The first and second interposed members are detachably/reattachably mounted between a mounting groove and the body member. A braking force of the braking member is configured to be adjusted by attaching/detaching first and second projection members to/from first and second concave portions that are formed in a mounting groove so that the first and second projection members can contact the inner peripheral sides of the first and second interposed members.

摘要:
First sounding mechanism, which issues sound when spool rotates relative to spool shaft, is furnished with sound-emitting member, pawl member, and plate spring. Sound-emitting member is non-rotatably mounted on spool shaft, and has multiple jags radially jutting on its outer periphery. Pawl member has body portion pivotably mounted on spool; pawl portion formed on the spool-shaft side of the swing center; and arcuate contact face formed on body portion on a side of the swing center SC opposite spool shaft. First-side radius R1 of contact face, is smaller than its second-side radius R2. Plate spring mounted on spool at an end nearer the first side of contact-face is, and contacts contact face at the other end, urging pawl portion of pawl member to collide with sound-emitting member. In a spinning-reel sounding device having a pawl member, the tone fluctuations due to spool rotational direction are controlled.
