    摘要： An explosion-proof type rotating electrical machine having excellent cooling and brush powder discharge capabilities. A drive shaft of a rotor is provided with slip rings for supplying current to a field coil, which is energized through brushes capable of activating the field coil by contacting with the slip rings. The brush compartment incorporated with the brushes and slip rings and the outside of the rotating electrical machine are connected with each other through an air suction path, the brush compartment and an inside space of the rotating electrical machine are connected with each other through an air blowing path, in which a flame stifling wire net is provided. When operating the rotating electrical machine in a flammable gas atmosphere, sparks generated due to a contact failure between the brushes and the slip rings ignite the flammable gas filled in the brush compartment to produce flames, the flames then reach the flame stifling wire net by a blowing cool air sucked from the air suction port, where the flames are cooled and extinguished by the flame stifling wire net. Brush powders are discharged to the outside of the brush compartment from the air blowing path by the cooling air.

    摘要： A direct current detecting device is disclosed in which two pairs of saturable cores are provided so as to enclose a conductor carrying a direct current to be measured. On each of the saturable cores, a bias winding, a feedback winding and an output winding are wound. First and second output circuits are provided, each connected with a pair of output windings and each including two closed current paths consisting of the output winding, a common load, a common A.C. supply source and a diode. The diodes function to allow the greater one of current flows of the two closed paths to be passed through the common load. An amplifier is connected to receive the difference between output signals of the two output circuits. The output of the amplifier is supplied to the feedback winding whereby the magnitude of the feedback current becomes a function of the magnitude of the current flowing through the conductor.

    摘要： A waterproof connecting structure for a pipe for connecting an intake passage of an internal combustion engine and an external gas detector to convey gas into the intake passage. The structure includes a connecting space to which the pipe is connected and a partition wall formed between the intake passage and the connecting space. The connecting space has a larger diameter than the pipe. The partition wall includes an elongate hole for placing the interior of the intake passage and the connecting space in fluid communication. This configuration prevents intrusion of droplets drifting in through intake air and allows a high degree of freedom for location of the pipe.

    摘要： In a vehicular alternator, a stator is arranged to oppose a rotor in a housing. The stator includes a stator core, which forms a plurality of slots extending in an axial direction of the stator core, and a stator winding wound around the stator core. The stator winding includes electric conductors held in the slots. Each of the electric conductors has a circumferential width that is smaller than a circumferential distance between a first wall and a second wall defining the slot. The first wall and the second wall oppose each other in a circumferential direction. The electric conductors are alternately in contact with one of the first wall and the second wall.
