  • Patent number: 6375436
    Abstract: A hybrid compressor achieving simplification in the structure and capable of driving the compression unit with ease is provided. An electromagnetic clutch unit (40) is provided at a rotating shaft (11) projecting out on one side of a compression unit (10) and an electric motor unit (70) is provided at the rotating shaft (11) projecting out on the other side of the compression unit (10), so that an electromagnetic clutch unit (40) in the prior art can be utilized directly. At the same time, since the electric motor unit (70) is provided at the rotating shaft (11) projecting out the other side of the compression unit (10), the electromagnetic clutch unit and the electric motor unit are set at the same rotating shaft (11) and the compression unit (10) and the electric motor unit (70) are positioned next to each other to reduce the torsional torque generated at the rotating shaft (11).

  • Patent number: 4733540
    Abstract: A control system for controlling operation of a compressor of a vehicular air conditioning system. The control system comprises an electromagnetic clutch which is adapted to disengage so as to cut the drivable connection of the compressor with an engine. The electromagnetic clutch is in an electric circuit including a first switch adapted to close in the overheat condition of a fuel system, and a second switch adapted to close at an abrupt vehicle acceleration. Additionally, a timer is provided in the electric circuit to maintain the disengaged state of the electromagnetic clutch for a predetermined time upon close of both the first and second switches thereby to stop the operation of the compressor, thus improving vehicle acceleration performance under the fuel system overheat condition.

  • Patent number: 4409861
    Abstract: A dial type wire control device includes a drum and a strap or band in combination. The drum is connected to a dial member through a connecting shaft so that the drum and the dial member can rotate synchronously. The band is to be wound on the periphery of the drum when the drum rotates in one direction and to be unwound when it rotates in the opposite direction. Thus, the wire is pulled or pushed to control a subject in a conventional manner.
