Abstract: In a double-layered construction corrugated tube 23 of a wire harness 21 which are provided on an outer side of a high voltage cable 22, an outer corrugated tube 26 is formed without a slit. In addition, an inner corrugated tube 27 is formed so as to be inserted from one end to the other end of the outer corrugated tube 26 with the high voltage cable 22 accommodated therein. The inner corrugated tube 27 is formed so that a pitch P1 between adjacent ridge portions 38 thereof is narrower than a pitch P2 between adjacent groove portions 30 of the outer corrugated tube 26.

Abstract: An image-forming-apparatus simulation apparatus includes a storing section, a first acquiring section, a generating section, a display section and a control section. The storing section stores a defective event table. In the defective event table, event specifying information are associated with image correction rules. Each event specifying information represents a defective event relating to an image forming apparatus. Each image correction rule represents a method for simulating an influence of a defective event on an image formed by the image forming apparatus. The generating section selects at least one image correction rule. The generating unit executes image processing on target image data based on the selected image correction rule to generate defect-image data representing a defect image expected to be formed on a recording medium when the defective event occurs.

Abstract: In a variable venturi type carburetor having a slow speed system, a fuel vapor conduit is provided, an inlet of which is open to a main fuel passage, an outlet of which is open to an intake passage. Fuel vapor occurring in the main fuel passage is carried through the fuel vapor conduit, so as not to be introduced into a slow fuel passage; thereby, the engine is rotated stably with a relatively lean air-fuel ratio.

Abstract: A variable venturi-type carburetor comprising a metering jet and at least one air-bleed bore formed on the cylindrical inner wall of the metering jet. The amount of air fed into the fuel passage of the carburetor from the air-bleed bore is controlled by an output signal from the oxygen concentration detector arranged in the exhaust manifold so that the air-fuel ratio of the mixture fed into the cylinder of the engine becomes equal to the stoichiometric air-fuel ratio. The metering needle is arranged so that it contacts the cylindrical inner wall of the metering jet and partially covers the air-bleed bore.

The upstream end portion of the tip face of the suction piston and the tip edge of the raised wall define an isosceles triangular air inlet opening therebetween when the amount of air fed into the cylinder of the engine is small.

Abstract: A variable venturi-type carburetor comprising a vacuum chamber and an atmospheric pressure chamber which are separated by a suction piston. A needle is mounted on the central portion of the tip face of the suction piston. A suction hole, interconnecting the vacuum chamber to a venturi portion of the carburetor, is formed on the tip face of the suction piston at a position located upstream of the needle. The vacuum chamber is open to the atmosphere via a flow rate control valve apparatus when the engine temperature is low. The vacuum chamber is disconnected from the atmosphere by the flow rate control valve apparatus when the engine temperature is high.
