Abstract: The present invention relates to a method for providing a semi-worked product and a mandrel covered with a long body which is the semi-worked product, in which the semi-worked product is a long body which is formed without a gap by spirally winding at least one sheet of film, at least one sheet of film of the at least one sheet of film is made of at least polytetrafluoroethylene, the long body has a thickness of 5 ?m or more and 75 ?m or less, and the long body is provided in a state of being in contact with a mandrel.

Abstract: The fish hook tying tool provides a rotating fish hook holder for a fish hook, and an adjacently mounted cutter for a fishing line, thus providing a combined tool for assisting a fisherman in tying fishing line to a fish hook and the trimming the knot after tying the fishing line. The fish hook tying tool includes a hollow housing having opposed front and rear walls, the front wall having an arcuate slot defined therein. In use, the user slides a lug along a path defined by the arcuate slot to drive rotation of a drive gear mounted within the hollow housing. Manual rotation of the drive gear drives a pinion to rotate, which, in turn, selectively drives a coaxially mounted fish hook holder to rotate with the shank and eye of the fish hook extending away from the tool. An attached clamp secures the tool to a support.

Abstract: A production method for a medical instrument includes a plurality of integrated hollow fiber membrane producing a base material forming a cylindrically-shaped body. Each of the hollow fiber membranes sequentially passes through a first point, a second point, a third point, a fourth point, and a fifth point that are set on a core member. In an outward path heading toward the third point from the second point, the hollow fiber membrane reaches the third point from the second point at the shortest distance while being wound in the circumferential direction of the core member. Moreover, in a homeward path heading toward the fifth point from the fourth point, the hollow fiber membrane reaches the fifth point from the fourth point at the shortest distance while being wound in the circumferential direction of the core member in the same direction as in the case of the outward path.

Abstract: A winding apparatus for and a method of applying a winding of a band-like material to a limb of a transformer core. The winding apparatus includes a guide member arranged to be fixed in relation to the core limb and a rotary member carrying a supply of a band-like material.
