摘要:
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.
摘要:
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.

A pipe inner surface inspection apparatus that can accurately inspect the inlet portion of a pipe is provided. The pipe inner surface inspection apparatus provides a guide unit (13) that is inserted into a pipe head (5); stabilizers (15) (17) that are installed on the guide unit (13) with gaps therebetween in the axial direction and substantially align the axial center of the pipe head (5) and the axial center of the guide unit (13); a drive shaft (19) that moves in an axial direction and around an axial center and engages the guide unit (13); and an inspection portion (21), for inspecting the condition of the inner surface of a pipe head (5), is rotatably installed on pivot shafts extending in a direction normal to a plane perpendicular to the axial center of the pipe head (5) at the center position in an axial direction at a rearward position more separated in an axial direction than the portion of the guide unit (13) sandwiched between the stabilizers (15) (17) and the stabilizer (17) side end portion is positioned at the axial center side, and in an unloaded state, is energized so as to always move within a range in which the diameter of the outer peripheral side position of the stabilizer (17) side end portion is smaller than the inner diameter of the pipe head (5).
