Filed: 1996-11-15
Abstract: PROBLEM TO BE SOLVED: To provide a tile for facing with adhesive lightweight and high in manufacturing yield by making bulk specific gravity in a specific range, and making in a specific range facing finish weight per unit area. SOLUTION: A plurality of thin tiles 3 are provided on the surface of a lightweight base material 2, joint intervals 4 between the tiles 3, 3 are provided and adhered to make tile stretching siding 1. The tile 3 has bulk specific gravity of 1.0-1.9, and stretching finish weight per unit area is 5-8kg/m<2> . In the tile, a forming agent is added to an adhesion raw material, molded, baked and manufactured. A blend amount of the foaming agent is selected so that the bulk specific gravity is 1.0-1.9. When the bulk specific gravity is 1.0 or lower, unevenness of foaming magnification per each tile becomes large, and size yield by backing is lowered. When the bulk specific gravity exceeds 1.9, tile weight becomes heavy unless the tile thickness is made small, and tile stretching finish weight becomes excessive. Thus, the lightweight foaming tile whose faced finish weight is 5-8kg/m<2> can be manufactured at high yield.

Filed: 1987-12-02
Abstract: PURPOSE:To avoid the sense of incongruity from giving to a listener by adopting a constitution such that the degree of separation is controlled stepwise or continuously between the stereo state and the monaural state in response to a multi- path noise so as to avoid the sound field fluctuated as a tremolo. CONSTITUTION:If no multi-path noise takes place, a voltage level applied to a separation control section in a stereo demodulation circuit 16 depends only on a received electric field intensity. That is, the degree of stereo separation of the stereo demodulation circuit 10 varies with the output of a level detection circuit 17 connected to the level meter terminal of an intermediate amplifier 13. If multi-path noise is generated, the voltage level applied to the separation control section depends on the multi-path level as well as the received electric field intensity. That is, a multi-path noise detection circuit 18 connected to the level meter terminal of the intermediate amplifier 13 detects the multi-path noise, thereby controlling the degree of separation stepwise or continuously in response to the multi-path noise.
