    摘要： To realize virtual surround reproduction with small deterioration in the SN ratio of an entire reproduction system, in the case of adding together virtual surround signals and front-channel audio signals in an adder 1300, volume normalization is carried out in a volume normalizing section 1200 before the addition. In the case where the addition is not performed, the virtual surround signals and the front-channel audio signals are output independently of each other without being subjected to volume normalization in the volume normalizing section 1200.

    摘要： This invention relates to a water-soluble fiber and a method of manufacturing the fiber. The water-soluble fiber of the invention is composed of a high molecular compound with a weight average molecular weight of not less than 10,000, which high molecular compound is obtainable by reacting a polyalkylene oxide compound, which is obtainable by addition polymerization of an ethylene oxide-containing alkylene oxide and an organic compound containing two active hydrogen atoms, with a polycarboxylic acid, an anhydride thereof, a lower alkyl ester thereof, or a diisocyanate and is manufactured by spinning the same high molecular compound. The water-soluble fiber of the invention is not only high in elongation and tensile strength but is readily soluble in water.

    摘要： A loudspeaker system having wide-directional characteristics includes a loudspeaker body having a polyhedron shape, preferably of dodecahedron and a plurality of speakers disposed on outer surfaces, respectively, of the polyhedron-shaped loudspeaker body in a manner that axial lines of adjacent two speakers intersect each other at a predetermined angle. A correction filter is further operatively connected to the speakers, and the correction filter provides a correction value set so as to obtain a flatness of sound pressures at various portions around the loudspeaker body.

    摘要： A high-speed current switch circuit of this invention has an n-type MOS transistor Q11 which switches and outputs a current, and a control circuit 11 which performs switching control of the MOS transistor Q11. In the control circuit 11, a source follower is formed by an N-type MOS transistor Q12 and a constant current source I2 which is a load on this transistor. A switch SW11 is connected to the MOS transistor Q12 to perform switching control of a current flowing through the MOS transistor Q12. The control circuit 11 includes a switch SW12 capable of grounding the gate of the MOS transistor 11. The source of the MOS transistor Q12 is connected to the gate of the MOS transistor Q11. Thus, even if a large current is caused to flow through the output transistor, the output transistor can be made to operate for switching at a high speed.

    摘要： A synchronization signal detecting section is internally provided with a stream type counter for counting stream type information output from a header information analyzer and a stream type determining section for instructing, based on a value in the stream type counter, a signal processing section to initiate stream conversion. If the value in the stream type counter reaches a predetermined value, it is determined that the input signal is a stream signal. If the value in the stream type counter does not reach the predetermined value, synchronization signal detection is restarted from the address which is one bit ahead of an address stored in a synchronization address storing section.
