摘要： A semiconductor laser device includes an optical fiber having an optical fiber grating formed therein, a semiconductor laser having an active layer with a single quantum well, for emitting laser light, and a coupling optical system for coupling the laser light emitted out of the semiconductor laser into the optical fiber. The coupling optical system can include a narrow-band filter for adjusting an incident angle of the laser light emitted out of the semiconductor laser. The optical fiber grating can have a reflection bandwidth wider than or substantially equal to a 3dB bandwidth of the gain of the semiconductor laser or a spectrum full width at half maximum of the laser light of the semiconductor laser.

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.
