Abstract: The present invention provides a compact air induction system for an internal-combustion engine in which an air inlet section, a collection section and the intake port section for a plurality of cylinders of the internal-combustion engine are formed adjacent to each other and connected directly or through a partition wall. A control unit for controlling the engine is mounted in the passage at the downstream of the air inlet section.

Abstract: A control device in an internal combustion engine, interlocking with a device to generate swirls in a combustion chamber of the internal combustion engine by providing bypass passages which allow air to bypass a throttle valve for regulating intake air flow rate of the internal combustion engine to control an output power of the internal combustion engine and allow the air to flow in from the side of atmosphere to communicate with air intake ports for respective cylinders on the downstream side of the throttle valve.

Abstract: An air intake system for an internal combustion engine uniformly distributes the fuel-air mixture in the cylinder, and concentrates the mixture in the vicinity of an ignition plug in the cylinder by selecting the direction of supply of sprayed fuel, thereby improving ignitability of the mixture at the time of lean-burn operation. The system produces tumble flow in the cylinder for accelerating combustion and provides lean-burn operation, thereby suppressing consumption of the fuel and reducing the amount of exhaust gas. The fuel is injected by a fuel injection valve and collides with an intake valve, before being atomized. The atomized fuel flows into the cylinder from the side of the intake valve closer to the fuel injection valve. On the other hand, high-velocity air flow from bypass passages enters the cylinder from the side of the intake valve closer to the ignition plug, so as to produce tumble flow in the cylinder.

Abstract: The suction is provided as an integral member which includes a casing having an air inlet and a plurality of ports forming outlets to the engine cylinders, a filter in the casing for filtering air flowing through the air inlet, a collection chamber in the casing for receiving air from the filter, at least one throttle valve in the casing for controlling the flow of air from said filter to said collection chamber, and a plurality of suction pipes for communicating with the respective cylinders of the engine through said outlets. The suction device can be made compact to thereby more effectively use the engine compartment of an automobile.

Abstract: A storage apparatus such as a copier or facsimile machine which stores information on paper and uses parts which the operator replaces upon expiration because of consumption of the part or deterioration of the part. A system is provided so that the consumable part can have its life-time measured by devices on the main body of the storage apparatus. Each consumable part has an indication of what stage of consumption or state within its life-time that it has reached. That is, for a copier after a certain number of copies are made one of a number of fuses in the consumable part can be fused as an indication of the state of the part.

Abstract: Digital information representing a displayable image is selectively modified to create various rotation effects, including rotations of the viewed image about various lines in its display plane and angular rotations within that plane. In the modification process, the information is moved between source and destination areas in a data processing system memory, without requiring intermediate buffer storage of the information during the process and therefore without requiring additional processing steps associated with intermediate buffer storage. The source and destination areas are of equal size and may overlap. This technique is applicable to document scanning apparatus as well as computer display apparatus.

Abstract: A backing for tufted carpets, having improved tufting properties such as a small penetration resistance to tufting needles, a uniform distribution of values of penetration resistance and yet superior intrinsic properties, and a tufted carpet produced from the backing are provided, which backing is produced by weaving polypropylene tape yarns oriented by stretching, these polypropylene tape yarns comprising foamed polypropylene tape yarns having a foam content of 1.0 to 20%.
