Publication number: 20040031472Abstract: A fuel supply system for use in an internal combustion engine, comprising: an intake passage; a downstream fuel injection valve near the port of each cylinder of the engine and downstream of the intake passage; and a controller, wherein the intake passage includes a fuel injection/evaporation device which has an upstream fuel injection valve; a heater for evaporating injected fuel; and an air passage for supplying the injected fuel with air. The controller is adapted to control the amount of fuel injected from the downstream fuel injection valve and the upstream fuel injection valve, thereby controlling the fuel-air ratio of the injected fuel.Type: ApplicationFiled: August 14, 2003Publication date: February 19, 2004Applicant: HITACHI, LTD.Inventors: Masami Nagano, Takanobu Ichihara

Publication number: 20040031474Abstract: A device 10 for illuminating luminescent paintballs before the paintballs are projected down the barrel of a paintball gun includes a conduit 12 configured to form a forty-five degree angle to promote the arranging of luminescent paintballs into a single row as the paintballs “fall” from an enclosure and into the conduit 12 to ultimately exit the conduit 12 and drop into a discharge mechanism, a plurality of ultraviolet lamps 14 that are positioned about an inner portion of the conduit 12 to illuminate the luminescent paintballs thereby urging the paintballs to “glow” in the dark, a “horseshoe” configured bracket 16 that disposes the lamps 14 at preselected portions of the conduit 12 that maximizes the exposure of the paintballs to ultraviolet light from the lamps 14, a low voltage D.C.Type: ApplicationFiled: June 13, 2003Publication date: February 19, 2004Inventor: Paul M. Ciesiun

Publication number: 20040031475Abstract: A portable concrete saw has a rotating concrete cutting blade that is rotated about a rotational axis by rotating drive shaft mounted to the saw and driven by a motor on the saw. A threaded recess in a distal end of the drive shaft is aligned parallel to the rotational axis but offset from that axis. An arbor sleeve is mounted to rotates with the distal end of the drive shaft. The sleeve has a non-symmetric blade mounting portion thereon to orientate the cutting blade in only one orientation. The sleeve has a hole therethrough parallel to the rotational axis through which the distal end of the shaft extends. A clamping plate has a recess aligned with and configured to receive at least one portion of the blade mounting portion in order to align the plate to rotate about the rotational axis. The plate has a geometric center with a hole through the plate parallel to the rotational axis but offset from the geometric center.Type: ApplicationFiled: August 16, 2002Publication date: February 19, 2004Inventor: Charles E. Markley

Publication number: 20040031476Abstract: A semiconductor wafer saw and method of using the same for dicing semiconductor wafers are disclosed comprising a wafer saw including variable lateral indexing capabilities and multiple blades. The wafer saw, because of its variable indexing capabilities, can dice wafers having a plurality of differently sized semiconductor devices thereon into their respective discrete components. In addition, the wafer saw with its multiple blades, some of which may be independently laterally or vertically movable relative to other blades, can more efficiently dice silicon wafers into individual semiconductor devices.Type: ApplicationFiled: August 19, 2003Publication date: February 19, 2004Inventors: Warren M. Farnworth, Tom A. Muntifering
