Abstract: In a Stirling cooling apparatus, a refrigerant is circulated within a refrigerant circulation circuit in such a way that the refrigerant receives cold, as latent heat, from a Stirling chiller and then releases the cold, by absorbing heat of vaporization, as it vaporizes in an evaporator, thereby cooling the inside of a refrigerator chamber. As the refrigerant, carbon dioxide, a natural refrigerant, can be suitably used.

Abstract: An adsorbent for adsorbing fuel vapors is disclosed. The adsorbent is to be disposed in an inlet system of an internal combustion engine. It has pores, and 50% by volume or more of the pores have a pore diameter falling in a range of from 1.4 to 2.8 nm. It exhibits a unit pore volume of 0.3 mL or more with respect to 1 mL thereof. It is formed as a particle. It exhibits high performance on adsorbing fuel vapors, and shows high durability even when it is used for long period of time.

Abstract: A throttle valve is opened after stopping an engine to prevent the valve from sticking. Then, when a temperature of the valve has become lower than the polymerization temperature, the valve is closed to seal the vapor of the HCs in a surge tank downstream. Changes in the temperature of the valve are, for example, estimated based on a temperature of an intake air detected by an intake temperature sensor.

Abstract: An intake device for an internal combustion engine has: a first intake pipe which is connected to the engine so as to conduct an intake air to the engine, and which has an opening portion that is provided in an upstream-side lower portion of the first intake pipe located at an upstream side in a flowing direction of the intake air; and a second intake pipe which has a downstream-side end portion that faces an upstream-side end portion of the first intake pipe, with a gap formed therebetween, and which conducts the intake air to the first intake pipe. An unburned gas reflux passage is provided for conducting an unburned gas from the engine to the first intake pipe. A container surrounds the gap and the opening so as to receive the unburned gas flowing from the opening portion. Thus, it becomes possible to prevent release of unburned gas into the atmosphere by performing a simple process on a conventional structure.

Abstract: In construction of a mechanical component such as a pin or a strip, at least one curved section extending in the moving direction is formed on the contact end of the component, or at least one inclined section converging in the chain entry side is formed on the contact end of the component; and/or a curved or inclined section is formed on the contact end of the component extending at least partially in the vertical direction; and/or at least one groove extending in one of the vertical and moving directions is formed in the contact end of the component.

Abstract: An absorbent, such as, for example, an active carbon, is provided in an intake air passage, for example, in an air cleaner, to efficiently adsorb fuel vapor. To ensure that fuel vapor adsorbed into the intake air passage can be efficiently desorbed even when there is only a small amount of the intake air, an intake throttle valve is provided upstream of the adsorbent and an opening of the intake throttle valve is throttled so as to decompress an area near the adsorbent. Desorption of fuel vapor also can be efficiently promoted by using a heater to directly heat the adsorbent in the intake air passage or by heating the intake air to indirectly heat the adsorbent.

Abstract: The present invention provides a method of machining a female screw groove in a workpiece whereby the spindle of an internal grinding wheel for machining the workpiece into a female screw is tilted relative to the screw's axis at an angle (&xgr;) smaller than the lead angle (&agr;) of the female screw. First, specifications of the female screw, data on the configuration of the thread groove, and the tilt angle are supplied to a program for calculating data on dressing of the grinding wheel wherein the locus of the groove on cross-sections normal to the axis of the grinding wheel and wheel dressing data are calculated. Second, the grinding wheel on the aforementioned spindle is shaped or dressed by simultaneous triaxial control of the rotation of the single point dresser about a b-axis, and the feed of the grinding wheel table along a z-axis and a cross slide along an x-axis based on the foregoing data. Thereupon, the female screw is machined with the dressed grinding wheel.
