摘要:
In a vehicle for off-road use, an engine is mounted on a lower portion of a body frame, a carburetor is attached to the engine, and a main air cleaner is attached to the carburetor. The carburetor is provided with an air vent unit attached thereto, for transferring atmospheric pressure to fuel in a float chamber in the carburetor, and a supplemental air cleaner is attached to the tip of the air vent unit. The supplemental air cleaner is disposed above the engine, and above and anterior to the carburetor and the main air cleaner. Since the supplemental air cleaner is substantially covered, from below, by the internal combustion engine, the carburetor, and the main air cleaner, fluids splashed up from a road surface can be blocked by these components, so that the supplemental air cleaner is substantially prevented from being exposed to splashed fluids.

The object is to enable highly accurate and high-speed estimation of quality-deteriorated areas. The quality-deteriorated area estimating device comprises: a flow quality information collecting unit for collecting flow quality information including a transmitter address, a receiver address, and communication quality of a flow flown by a network user; a route information collecting unit for collecting structure information of the network; a flow-quality/via-link table managing unit and a table storage unit for finding, based on the collected flow quality information and the structure information of the network, a link that the flow goes through, judging occurrence of quality deterioration in the flow, and managing a result thereof in a table; and a quality-deteriorated area estimating unit for outputting, when there is quality deterioration in one or more flow, a subset including the link that an arbitrary flow with quality deterioration goes through among the subset of the set of links that the set of the arbitrary flows with the quality deterioration go through, which also has the minimum number of elements, as a quality deteriorated area in the table managed by the flow-quality/via-link table managing unit.

A premixed air-fuel mixture supply device is joined to a combustor liner included in a combustor for a gas turbine or an aircraft engine. The premixed air-fuel mixture supply device has a pilot fuel injection unit having an inner wall, and a prevaporizing, premixing main fuel injection unit having an outer wall surrounding the inner wall. A combustion air passage is defined by the inner and the outer wall. An intermediate wall is disposed in the combustion air passage so as to divide an upstream part of the combustion air passage into a secondary combustion air passage surrounding the inner wall, and an outer combustion air passage surrounding the intermediate wall. Fuel inject holes are formed in the intermediate wall to inject fuel radially outward into the outer combustion air passage. A swirling device is disposed in the secondary combustion air passage to swirl combustion air flowing through the secondary combustion air passage. An atomization lip is formed in a tail part of the intermediate wall.

This invention consists in improvements in a buried-heterostructure laser with buried optical guide, and facilitates the oscillation of the laser in the fundamental mode thereof and also enhances the available percentage of production of the laser. An active layer and an optical guide layer are sandwiched between two cladding layers, to form an optical confinement region. The width of the semiconductor material assembly varies in the direction of the stacked layers, and the narrowest part thereof is located on a side opposite to the optical guide layer with reference to the position of the active layer. The side surface of said semiconductor material assembly parallel to the traveling direction of laser radiation is buried by a burying layer.
摘要:
In a distribution type fuel injection system, the injection advance angle, or the relative angular position at which fuel injection begins, is controlled by a first spring loaded piston (44). The spring force is opposed by pressurized fuel from a pump (14), the pressure increasing with engine speed. A second spring loaded piston (49) moves the first piston (44) to an advanced position for starting the engine and is retracted when the fuel pressure reaches a certain value to retard the advance angle in an idling speed range. The fuel pressure moves the first piston (44) to progressively advance the angle in a higher speed range. An O-ring (61) is provided to an end of the second piston (49) which abuts against an end wall (53) so that the fluid pressure receiving area of the second piston (49) is small when the second piston (49) abuts against the end wall (53) but is greater when the second piston (49) is moved away from the end wall (53). The effect is that the second piston (49) is prevented from moving and retarding the advance angle until the engine speed and fuel pressure reach a relatively high value upon starting of the engine. Thereafter, the advance angle will be retarded upon a return of the engine speed to the idling range.
