  • Patent number: 4802456
    Abstract: An engine comprising a mechanically driven charger arranged in the intake passage downstream of the throttle valve. A bypass passage is branched from the intake passage between the throttle valve and the mechanically driven charger and connected to the intake passage downstream of the mechanically driven charger. A relief valve is arranged in the bypass passage to control the maximum charging pressure produced in the intake passage downstream of the mechanically driven charger. The relief valve is controlled so that the maximum charging pressure is increased when the engine is operating at a low or middle speed, and the maximum charging pressure is reduced when the engine is operating at a high speed.

  • Patent number: 4683666
    Abstract: A coffee roasting apparatus which includes a coffee roaster device which comprises a cylindrical container formed preferably of glass material, a cylindrical drum rotatably extending within the center portion of container, and a heater element disposed within the drum. The drum is formed of wire cloth and driven by a motor. Coffee directly receives radiation heat through the drum. Also, the roaster device is rotatably supported in a housing, which is provided with a cooling space which enables the apparatus to automatically proceed to the discharge of the roasted coffee beans. The interior of the roaster device and the cooling space are connected by an open air circulating pathway. Therefore, the cooling of the roasted coffee beans and the interior of roaster device are separately accomplished with a single air pathway.
