摘要： To provide a Fresnel lens wherein changes in focal length due to temperature dependence of the refractive index can be compensated. By introducing a fractal structure into prisms in a peripheral region in which the prism angle is large and therefore the aspect ratio h/p of the prisms is large, the aspect ratio is reduced from h/p to h'/p and the slope of the envelope 20 to the underside of the slopping face is reduced, and thereby a shape in which a change in focal length due to temperature dependence of refractive index can be compensated for by a change in the shape of lenses due to expansion/contraction, is obtained.

摘要： A covering device including an elastic covering member (15) in a hollow cylindrical shape, having an inner diameter in a contracted state smaller than an outer diameter of a cable portion to be sealed, and a core (11) in a hollow cylindrical shape, having an inner diameter larger than an outer diameter of the cable portion to be sealed, on the outer periphery of which the elastic covering member (15) is mounted in an expanded state. The elastic covering member (15) and core (11) are arranged while surrounding the cable portion to be sealed so that the contracted elastic covering member (15) closely covers the cable portion to be sealed when the core (11) is pulled out therefrom. A slip member (13) having a low surface friction is interposed between the inner periphery of the elastic member (15) and the outer periphery of the core (11) to facilitate removal of the core (11).

摘要： When using an acrylic resin with a refractive index of 1.494, for example, the structure of the Fresnel lens is such that in a segment where a deviation angle of 19.5° or less is required, refraction-only prisms which do not cause any reflections are used, while in a segment where a deviation angle of 31.0° or larger is required, single-step total reflection prisms in which light is totally internally reflected once and then refracted are used and, in a segment where a deviation angle not smaller than 19.5° but not larger than 31.0° is required, two-step total reflection prisms in which light is totally internally reflected twice and then refracted are used.

摘要： [Problems] To provide a body section with sufficient rigidity without impairment of the sliding facilitating ability of a sliding section of a slidingly detachable core member included in a cold shrink tube unit. [Solving Means] A slidingly detachable core member 12 includes a body section 22 that forms a hollow cylinder, and a sliding section 24 that is integrated with one axial end of the body section 22 and is so flexible as to be turned over to lie on the outer circumferential surface of the body section 22. The body section 22 consists of a plurality of plate-like portions 26 that are assembled to form the hollow cylinder. The sliding section 24 consists of a plurality of porous structural parts 28 that are formed adjacently to the plate-like portions 26 respectively. The core member 12 is incorporated in a seal region of an elastic tube member included in a cold contractile unit with the sliding section thereof turned over to lie on the outer circumferential surface of the body section 22. The core member 12 has pull tabs 30 that are integrated with the body section 22 while being isolated from the sliding section 24.
