Abstract: An air-fuel mixture generating device includes a main body equipped with a diaphragm-type fuel pump, a fuel injection valve attached to the main body, and a manual fuel pump attached to the main body for filling a fuel passageway with fuel when the diaphragm-type fuel pump is not operating. The manual fuel pump has an inlet port which communicates with the fuel passageway and a pressure-adjusting valve disposed at the inlet port of the manual fuel pump, thereby enabling it to act not only as an intake valve when the manual fuel pump is operated but also as a relief valve for allowing the fuel inside the fuel passageway to escape into a pump chamber of the manual fuel pump when the pressure of fuel inside the fuel passageway exceeds a predetermined pressure.

Abstract: A muffler for an internal combustion engine has a vertically elongated expansion chamber into which an exhaust gas from the exhaust port of internal combustion engine is introduced. The expansion chamber is separated level-wise into a first expansion chamber and a second expansion chamber by a partition plate. An exhaust emission purifier formed of an oxidation catalyst is attached to the partition plate, thereby allowing the exhaust gas ejected from the exhaust port to be introduced into the second expansion chamber from the first expansion chamber via the exhaust emission purifier. The exhaust emission purifier is spaced apart from the exhaust port by a predetermined distance in a direction orthogonal to an ejecting direction of the exhaust gas.

Abstract: When a content to be partialized is specified to a document, the document creation supporting system records the content of the part in a file separated from the document together with a part holding mark, adds a part reference mark at the position where the part is specified in the document and deletes the content of the part from the document in order to be able to readily confirm the consistency of the part and version number when the document is updated and to be able to confirm contents of documents among a plurality of documents.

Abstract: A muffler for a two-stroke internal combustion engine includes an expansion chamber into which exhaust gas ejected from the exhaust port of the engine is introduced. An air-supplying device is adapted to supply outside air to the expansion chamber. The air-supplying device is actuated by taking advantage of the pressure pulsation in the crank case of the engine, and is constituted by a diaphragm pump.

An exhaust port and scavenging ports are configured and disposed such that they are open in a reduced period of the combustion cycle.

Abstract: A muffler for an internal combustion engine has an expansion chamber (31, 32) into which exhaust gas from the engine is introduced. The expansion chamber has a double wall (32A), with an inner panel (42) of the double wall (32A) having exhaust gas discharge portions (42A, 42B, 42C, 42D) with respective blowout holes (61, 62, 63, 64) for introducing the exhaust gas from the expansion chamber (32) into an air space (Sb) in the double wall (32A). From the air space (Sb), the exhaust gas is vented to the ambient through a discharge hole (37A) in an outer panel (42) of the double wall (32A ). A spark arrester screen (72) covers the discharge hole (37A).

Abstract: In a two-stroke internal combustion engine, total hydrocarbon (THC) exhaust is decreased as a result of small structural changes and without loss of output power. A Schnurle scavenging-type combustion chamber has a hemispherical main surface and an annular skirt-like squish band, and a spark plug is disposed for a spark point to be substantially at the center of the combustion chamber. The squish band has minimized width.

Abstract: Clock skew is minimized in an ASIC by grid-partitioning the IC chip into a number of preferably equal sized regions. An on-chip clock or buffer unit provides a clock signal to be distributed to buffers and clocked loads also on the IC. Equal length metal interconnect traces are formed in a preferably "H"-shaped configuration such that the termini and the center of the traces overlie buffer regions that will receive the distributed clock signal. Metallization interconnect paths are dictated by placement of joiner cells. By making each metal interconnect trace equal in overall length and in layer sub-lengths (if multiple metallization layers are present), clock skew along the interconnect traces is minimized macroscopically. A series of prioritized net lists is generated, defining interconnect paths to each region. A buffer is centrally located within each region, and is surrounded by a ring containing clocked loads to be coupled to the clock signal.
