The compound is useful as an additive in a rubber composition based on natural rubber or a diene-based synthetic rubber and a non-carbon inorganic filler to greatly improve the mechanical properties of the vulcanizate without increasing the Mooney viscosity of the unvulcanized rubber composition.
摘要:
A counter drive mechanism for use in a tape recorder having a resettable counter includes movable means preferably in the form of a rotatable disc having a tape engaging peripheral surface which abuts the tape such that the disc is rotated as the tape moves. The rotation of the disc is mechanically transferred to the counter to index same. Since the counter is driven in accordance with the movement of the tape, and not by the tape drive mechanism as is conventional, the accuracy of the counter is significantly enhanced. The peripheral surface of the disc is provided with a pair of electrically isolated conductive strips which, when electrically connected by contacting an electrically conductive foil strip on the tape, complete a circuit to energize the counter resetting means such that the counter is automatically reset at the appropriate tape position.

A body member to be exterior parts of a portable device used both outdoors and indoors has a coating film containing a photochromic dye provided on at least a part of an internal surface of a transparent base material. Further, a plastic is used as the transparent base material. Besides, an ultraviolet absorbent that absorbs an ultraviolet ray having a wavelength shorter than a wavelength region in which a color developed by the photochromic dye is expressed is diffused in the transparent base material made of the plastic. In addition, the coating film containing the photochromic dye is formed by a coating liquid that contains a class of hindered amine light stabilizer or a class of hindered phenol light stabilizer.
