Abstract: A wiper blade (1) comprising a base portion (3) to be attached to a wiper arm, a lip portion (4) to sweep away a water droplet or dust etc. adhered to a glass window, a thin neck portion (2) for connecting the lip portion (4) and the base portion (3), and a sweeping surface layer portion formed on a side surface of a cross section of the lip portion (4), the sweeping surface layer (7) comprising a scale-like powder (9) having good sliding property and a binder (10) comprising a water-repellency silicone-base rubber composition for binding the scale-like powder (9) to the lip portion (4). The scale-like powder (9) is laminated in a thickness direction of the lip portion (4) and the laminated scale-like powder is bound to each other with the binder (10).

Abstract: A key top member for a push button switch structure capable of facilitating change and modification of a design while eliminating deformation and misregistration of a display section, being accommodated to a variety of data, being increased in design properties and visibility, and being reduced in manufacturing cost. An upper resin sheet made of thermoplastic resin and having display sections such as a letter, a symbol, a pattern or the like printed thereon is formed with projections having configurations conforming to outer configurations of key top elements. The projections are each securely provided therein with a filler member made of photo-setting resin directly or through an adhesive.

Abstract: A key top element capable of being manufactured while permitting a design of a display section thereof to be readily modified and corrected, accommodating a variety of data for design formation, and capable of exhibiting increased design properties. The key top element includes a printed sheet constituted by a substrate sheet member, an on-demand printed layer and a white- or silver-colored layer, as well as transparent key top members fixedly bonded to the printed sheet. The on-demand printed layer is printed in the form of a symbol or the like on the substrate sheet member using an on-demand printing machine. A push button switch element is also disclosed which includes such a key top element and a light-permeable rubber cover base bonded to the key top element.
