  • Patent number: 5977888
    Abstract: A touch panel (4) and an operation part (30) are provided on display means (2). A permanent magnet (52) is mounted on a push button (32), and a magnetic metal plate (58) is mounted on a support frame (36). When the push button (32) starts to be pushed down toward the touch panel (4), the push button (32) moves toward the touch panel (4) against magnetic attractive force of the permanent magnet (52) and the magnetic metal plate (58), and an operation forward end part (46) operates a touch switch (4a). Stroke feeling results from this movement. Further, the aforementioned magnetic attractive force abruptly reduces in an initial period of this movement, and an operator of the push button (32) can attain click feeling. Since the stroke feeling and the click feeling are caused in the operation of the push button (32), operability is improved while making the best use of such an advantage that the touch panel (4) is of a thin type.

  • Patent number: 4378474
    Abstract: An electrical switch device manually operable, by a rotatable knob, to a plurality of definable positions for selectively effecting operation of an automotive transmission to a desired gear ratio. The knob and a housing, which includes the switch, may be mounted any place in the vehicle cab within convenient reach of the operator. The switch device is connected to an electronic logic system which monitors the condition of the transmission at all times to either energize or deenergize a lock-out solenoid, which controls a latch mechanism. Depending upon the condition of the transmission and, therefore, of the solenoid, a latch mechanism either permits or inhibits operation of the knob. An override mechanism permits the operator to release the latch mechanism to permit operation of the knob and the switch for shifting of the transmission, in an emergency situation, notwithstanding that the latch mechanism is in a locked position.

  • Patent number: 3984744
    Abstract: A speed control system for electric vehicles for varying the applied voltage to a series wound traction motor to vary the speed thereof by dividing the main power source into a number of small units, which are then grouped and re-grouped through a series of relays actuated by a controller to provide several values of voltage from low to high voltage in an orderly progressive manner. The circuit is also provided with a ballast or surge-limiting resistor in each grouping and re-grouping, resulting in a smooth power flow and thus smooth speed change while at the same time limiting the battery drain to a safe maximum. The ballast resistor is automatically shunted out of the power circuit as the vehicle picks up speed, thereby providing an intermediate control point between each battery re-grouping step.
