摘要： A driving circuit for a brushless motor having a permanent-magnetic rotor is disclosed which is capable of positively carrying out starting of the motor and rapidly interrupting exciting current to protect the motor, when the rotor fails to rotate during the normal operation. The driving circuit includes transistor control circuits each including a capacitor, a PUT, and a capacitor charging circuit comprising a Zener diode and a resistor; and a resistor series circuit for flowing conductive signal current to a transistor switch which serves to supply current to exciting windings. The PUT is conductive to allow the transistor switch to be kept non-conductive when the capacitor is charged to a predetermined voltage.

摘要： PROBLEM TO BE SOLVED: To enhance current interrupting performance by increasing generation of a gas from the surface of an insulation such as an arc chute, while increasing discharge of a hot gas by arcing. SOLUTION: The slit of the arc chute is extended in the direction facing the locus of a movable contact to form a gas exhausting passage, and one or more partition plates are provided in the gas exhausting passage on the almost same plane as the rotation plane of the movable contact or along its almost parallel plane. The sum of the widths of a plurality of slits formed by the partition plate provided in the gas exhausting passage is made equal to or larger than the width of the slit provided along the locus of the movable contact. From the wall surface of the slit provided along the locus of the movable contact till the wall surface of the gas exhausting passage having the partition plate, the wall surface is widen so as to form a taper shape.

摘要： PROBLEM TO BE SOLVED: To provide an air-break switch capable of being miniaturized, excellent in the performance of breaking small electric currents such as exciting currents of a transformer. SOLUTION: An arc-extinguishing room part 14 has a narrow gap part 14b in which a narrow gap is formed along the locus of movement of a movable electrode 12, and an insertion opening 14c. A buffer room 22a of a buffer room part 22 communicates with the narrow gap part 14b via a gas passage part 21. The pressure inside the arc-extinguishing room part 14 is raised by the arc when the electric current is broken, though the pressure rise is moderated by the buffer action of the buffer room 22a. Hot gas accumulated in the buffer room 22a returns to the narrow gap part 14b when the pressure in the narrow gap part 14b is lowered, and is discharged from the insertion opening 14c. Therefore, sudden spouting of the hot gas from the insertion opening 14c can be prevented when the movable electrode 12 is pulled out of the insertion opening 14c, and the earth fault to a switch housing 1, that is the earth electric potential, can be prevented. Accordingly, the switch housing 1 can be miniaturized.

摘要： PROBLEM TO BE SOLVED: To provide the space optical transmitter by which interruption of an optical path is warned for the user on the occurrence of the interruption in the optical path so as to surely inform the user of it. SOLUTION: The two space optical transmitters placed at positions apart from each other send a data signal with a light emitted to space in 2-way. The one transmitter is provided with a link pulse generating circuit 17 that generates a link pulse signal with a prescribed pulse width and a link pulse transmission circuit that sends the link pulse signal in the case of non-data transmission state where no data are sent. The other transmitter is provided with a link pulse detection circuit 19 that detects a link pulse signal sent from the one transmitter and a timer circuit 20 that receives a detection signal from the link pulse detection circuit 19 and provides an output of a signal to an alarm device 21 when the detection signal from the link pulse detection circuit 19 cannot be detected within a prescribed time.
