    摘要: When a gain control circuit is its maximum gain, an offset adjusting circuit generates an offset adjusting voltage so that an offset voltage included in an output signal of this gain control circuit becomes a target voltage within a dynamic range of a digital correction unit, and a control circuit adjusts an offset by adding the offset adjusting voltage to a control signal from a processing circuit in an adding circuit. In this case, a residual offset voltage included in an output signal of this gain control circuit is corrected by a digital correction unit. All of the electrical offset in the analog circuitry are not cancelled, but the offset adjustment is carried out to a range correctable by the digital correction circuit.

    摘要: A sound absorbing mechanism using a porous material has a sound absorbing plate of a thin plate porous material made by partially heating for welding plastic particles and a supporting member for supporting the sound absorbing plate and forming a back air space. More than one pair of resonators having a separated back air space in the aforementioned back air space are fixed to the sound absorbing plate, and the resonators are disposed to be opposed to a sound insulator with the supporting member between. Plural reflecting members or increased sound absorbers may be disposed to be opposed to the surface of the sound absorbing plate opposite to the surface equipped with the resonators, or a perforated protecting plate fixing the plural reflecting members or the increased sound absorbers thereon are may be equipped. The sound absorbing mechanism has a superior sound absorption characteristic from lower frequencies to higher frequencies.

    摘要: A method of producing an anti-slip shoe sole makes use of a shoe sole forming die having a plurality of independent, projection-forming cavities in the bottom thereof. The cavities open to a reverse side of the die through respective escape holes connected to the cavities. A foamable, unvulcanized green rubber containing hard fibers dispersed therein is set in the shoe sole forming die. Heat and pressure are applied to the unvulcanized green rubber to cause the unvulcanized green rubber to fill the cavities and further to flow into the escape holes, thereby forming a shoe sole blank having projections integral therewith. Buffing is effected on the bottom portions of the projections, thereby allowing ends of the hard fibers to appear in the ground-contact surfaces of the projections.
