    摘要： Provided is a flame-retardant thermoplastic resin composition in which any halogenated flame retardant is not used but a phosphoric flame retardant is used, which has flame retardancy meeting U.S. UL Standard 94 V-2, which exhibits excellent dripping performance during burning, and which is excellent in balance between properties. The flame-retardant thermoplastic resin composition contains 100 parts by mass of a copolymer mixture containing a graft copolymer (A) obtained by graft-polymerizing a rubbery polymer, a vinyl cyanide compound, and a copolymerizable vinyl compound and a vinyl copolymer (B) which is obtained by copolymerizing the vinyl cyanide compound and the copolymerizable vinyl compound and which has a mass-average molecular weight of 90,000 to 160,000 and 5 to 20 parts by mass of a phosphoric flame retardant (C) blended with the copolymer mixture. The content CB1 of vinyl cyanide units in the acetone-insoluble fraction of the copolymer mixture is 22.0% to 32.0% by mass, the content CB2 of vinyl cyanide units in the acetone-soluble fraction thereof is 22.0% to 34.0% by mass, and |CB1−CB2| is 0% to 3.0% by mass.

    摘要： A gain control circuit of the current mirror circuit type in which a current source for a first current mirror circuit is constituted with the output stage of another current mirror circuit. Among the junctions of the first current mirror circuit and the another current mirror circuit, the bias side junction of the first current mirror circuit is used as an input terminal and the other as an output terminal. A predetermined current is supplied to a resistor connected to the emitter of the bias side transistor of the first current mirror circuit to obtain a predetermined gain. Application of a signal to the resistor, which signal is opposite in phase to an input signal, serves to cancel the influence of the input signal to thereby eliminate fluctuations in the gain.

    摘要： Disclosed is a variable output-type constant current source circuit capable of varying its output current in a stepwise manner without the complication in circuit configuration and the increase in size of a semiconductor circuit board for incorporating the circuit therein. The constant current source circuit comprises a first self-biasing type constant current circuit 3a configured such that transistors M1, M2 are operable to cooperatively supply a given voltage across a resistor RS to generate a stabilized current IR1. In order to vary the output current, the constant current source circuit includes a switching circuit 5 (transistor M5) connected in series to a series circuit connecting in series the transistor M1 and the resistor RS, and a second constant current circuit 4 connected in parallel to a series circuit connecting in series the transistor M1, the resistor RS and the transistor M5. The second constant current circuit 4 is also configured to serve as an activation circuit for the first constant current circuit 3a.

    摘要： An object detecting system including an ultrasonic transducer element array including first to N-th ultrasonic transducer elements, a first means for intermittently supplying burst driving pulses to the ultrasonic transducer elements at different times in each of successive intermittent periods. Also, the object detecting system includes a second means coupled between each of the first to N-th ultrasonic transducer elements and the first means for applying the burst driving pulses to the first to N-th ultrasonic transducer elements, successively. The second means includes first to N-th delay circuits which delay applying the burst driving pulses to the ultrasonic transducer elements with the first to N-th delay circuits giving different delay time periods, respectively, so that the delay time periods are successively longer in the order from the first delay circuit to the N-th delay circuit and each of the ultrasonic transducer elements is supplied with the burst driving pulse through two kinds of the delay circuits connected in parallel in such a manner that the M-th number of the ultrasonic transducer elements is coupled with the M-th and (N-M+1) th delay circuits, with M being a number from one to N.
