Abstract:
A non-halogen series floor material includes an intermediate resin layer containing filler, resin having no chlorine atom in chemical structure as a primary resin ingredient and amorphous poly α-olefin resin whose number average molecular weight is 20,000 or less. The content of the amorphous poly α-olefin resin is 5 to 40% by weight with respect to entire resin ingredients. On the upper surface of the intermediate resin layer, a surface resin layer having a thickness of 30 to 1,000 μm is integrally formed. The surface resin layer includes no chlorine atom in chemical constitution. On the lower surface of the intermediate layer, a heat shrinkage-characteristic cloth is integrally formed by heating it to form a backing layer. This provides a non-halogen floor material that hardly generates toxic gases at the time of burning, can be manufactured at a low cost and is excellent in wear resistance, stain resistance, dimensional stability and workability.

The tile carpet has a structure in which a backing layer (A) of a composition comprising an amorphous polyolefin and a filler containing magnesium hydroxide; a glass or polyester non-woven fabric; a backing layer (B) of a compositon comprising an amorphous polyolefin and a filler containing magnesium hydroxide; a glass or polyester crossed fabric; and a carpet cloth having a sealer layer (C) of a composition comprising, an amorphous polyolefin and a filler, are laminated to one another successively in this order.
Abstract:
An AGC system controls the amplitude of a reproduction signal read out from a recording medium at a predetermined level by adjusting the gain of an AGC amplifier. The AGC system includes a differentiator which differentiates the output signal of the AGC amplifier and then outputs a resultant differential signal. A rectifier rectifies the output differential signal. An operation unit compares the output signal of the rectifier with a predetermined reference value and outputs an error signal corresponding to the difference between them. The gain of the AGC amplifier is adjusted according to the error signal so that the output signal of the AGC amplifier and the output signal of the differentiator may be controlled at respective predetermined levels. The amplitude level of a reproduction signal can be maintained at a predetermined level regardless of the MTF characteristics of an optical system or other factors and a single AGC circuit can provide both reproduction signals which are suitable for both mark edge recording and mark position recording.
