  • Patent number: 9620971
    Abstract: A battery charger is provided on which power conversion components for converting commercial power to direct current (DC) power are mounted. The power conversion components include a power breaker for switching input alternate current (AC) power on/off, a power conversion circuit for converting the input AC power to a predetermined AC power, a voltage conversion circuit for converting the predetermined AC power to a predetermined voltage, and a rectifier circuit for converting the AC power that has been converted to the predetermined voltage to DC power. The power conversion components are mounted on a core frame, and an outer housing is mounted to the core frame in a manner so as to cover the core frame. The power breaker, the power conversion circuit, the rectifier circuit, and the voltage conversion circuit are mounted in this order to the core frame.

  • Patent number: 4227595
    Abstract: A current transmitting system for use with a self-propelled automatically steered electric vehicle includes a pair of parallel, circularly arranged bus bars connected to a low-frequency A.C. power source, an induction cable extending along the bus bars and connected to a high-frequency A.C. power source, and a current collecting shoe slidable on and along each of the bus bars for transmitting the current carried by the bus bar to an electric device mounted in the vehicle. In this system, each of the bus bars is divided into two sections one of which is connected to the low-frequency A.C. power source through a coil.

  • Patent number: 4034680
    Abstract: The disclosure relates to a dual-mode bus which is operable on a guideway under automatic control and also operable on ordinary surface streets or highways under the control by a bus driver. The dual-mode bus comprises a rear axle having at both ends thereof traction wheels, a frame supported on the axle and a current collector. A floating support is connected between a differential gear housing of the rear axle and the frame and has two spaced portions, first one of which is disposed nearer to the axle than second one of the two spaced portions thereof. An arm having two spaced portions is provided, first one and second one of which are connected to the first and second portions of the floating support, respectively. The arm carries the current collector at a third portion spaced on the same side as the first portion of the arm, from the second portion of the arm. The third portion is spaced, further than the first portion of said arm, from the second portion of the arm.

  • Patent number: 3945455
    Abstract: A first link member branched into two straight arms at a fixed angle is pivotally supported by the vehicle body at the branching point, and the free end of the first arm is linked with a connecting rod which in turn is connected to a steering arm for a road wheel while the free end of the second arm is pivoted to an end of a straight second link member which is equal to the second arm in length, the other end of which second link member is pivoted to a middle portion of a rod supporting at the ends thereof a pair of guide wheels. The rod is provided with means to move the rod relatively to the vehicle body thereby to retract the guide wheels and rotate the second link member until it forms no angle between the second arm.
