Abstract: A fiber-reinforced member includes: a base member having a tubular region with an outer circumferential surface extending along and substantially in parallel with an axial direction; and a fiber-reinforced resin layer constituted of a tow prepreg wound in an overlapping manner to cover the outer circumferential surface of the base member along a predetermined direction crossing the axial direction when viewed in a radial direction of the base member, the tow prepreg serving as a widened tape-like member. The tape-like member constituting the fiber-reinforced resin layer has a portion having a fiber line extending along a direction crossing the predetermined direction. A size of a width of the tape-like member constituting the fiber-reinforced resin layer is not less than 100 times and not more than 400 times as large as a size of a thickness of the tape-like member constituting the fiber-reinforced resin layer in the radial direction.

Abstract: A band, a wristwatch with the band and a method of making the band are described. The band includes a strip-like body with a series of holes provided therein along a length thereof for adjusting an effective length thereof. The body includes a band-shaped support layer of woven or knit fabric of bundles of one or more kinds of fibers, the fibers being selected from a group including carbon fibers, glass fibers, aramid fibers and boron fibers. The body also includes a first resin layer adhering closely to one surface of the support layer, and a second resin layer adhering closely to the other surface of the support layer. The fibers of the support layer extend at a predetermined angle to longitudinal and transverse directions of the body.

Abstract: A golf club head having a primary body of a first material defining an opening. A cover of a second material which covers the opening and includes a periphery. The cover being unsuitable for welding with the primary body. A reinforcing edge mask having a first portion bonded to and at least partially covering the periphery of the cover and also having a second portion secured to the primary body.

Abstract: The present invention intends to prevent deviation and gap from being generated in a joining section of a golf club in which a head main body 10A and a surface material 10B are integrated by joining together and provide a high quality golf club head having an improved durability and manufacturing method thereof. In the golf club head in which the head main body 10A and the surface material 10B are joined together such that they are integral, a groove 18 is provided in a joining section between the both members and joint material 19 composed of fiber reinforced resin material is embedded in that groove. Consequently, the joining strength is intensified.
