  • Patent number: 10900411
    Abstract: The present disclosure aims to improve circulation of intake air and distribution of bypass intake air to cylinders, while reducing an increase in the overall height of an engine. A supercharger extends along a cylinder bank at a side of a surge tank extending along the cylinder bank. A bypass pipe branching off from an upstream intake pipe configured to introduce the intake air into the supercharger extends along the cylinder bank above the supercharger. A downstream side intake pipe configured to guide the intake air from the supercharger to the surge tank extends downward from the supercharger. The downstream intake pipe is, in a U-shape as viewed along the cylinder bank, connected to the surge tank.

  • Patent number: 7874070
    Abstract: An injection valve has a nozzle body, a valve needle positioned in the nozzle body, an actuator for actuating the valve needle, and an orifice plate fixed at an end of the nozzle body. The orifice plate has a valve seat for cooperating with the valve needle and an orifice for injecting a fluid. The orifice plate is provided with a projection having a convex-curved surface on an orifice outlet side of the orifice plate. A flat surface portion is formed in the area of the convex-curved surface, and the outlet of the orifice is located in the flat surface portion.

  • Publication number: 20080241330
    Abstract: The present inventions provides a process for producing ready-to-eat gelatin noodle which can inhibit the dissolution during the boiling step as well as the extension and the swell-up after cooking to result in producing ready-to-eat gelatin noodle which makes us feel suitable elasticity and comfortable chewing on eating it and is delicious. This ready-to-eat gelatin noodle is produced from a starting material of mixed starch which consists of potato starch and green-gram starch mixed with each other. A food base material such as carrot powder is kneaded into the mixed starch and 2 to 5 wt % of curdlan is added to the mixed starch containing the food base material. This mixed starch with the food base material contained is kneaded with water and is extruded into boiling water through a die to form lines of noodle. These lines of noodle are boiled with boiling water and then are washed with water to cool them. The thus cooled lines of noodle are frozen in a refrigerator and de-frozen.

  • Publication number: 20080233259
    Abstract: A process for producing instant bean-starch vermicelli (harusame) that is capable of suppressing not only dissolution during boiling but also elongation and swell after cooking, and that exhibits appropriate elasticity and gives firm palatability. This instant bean-starch vermicelli is produced from a mixed starch consisting of potato starch and mung bean starch as a raw material. In the mixed starch consisting of potato starch and mung bean starch, the content of potato starch is in the range of 30 to 70 wt. %. 0.25 to 5 wt. % of curdlan is added to the mixed starch. The resultant mixed starch is kneaded with water, and extruded into hot water through a die to thereby obtain linear noodles. The linear noodles are boiled with hot water, washed with water, and cooled. The thus cooled linear noodles are frozen in a freezer, thereafter thawed, cut into given lengths, weighed and dried by means of hot air.

  • Patent number: 7021569
    Abstract: A fuel swirler positioned upstream of an injection orifice is disposed at the tip of a nozzle body in a fuel injector, in which the fixed core and the nozzle body are coupled to each other via a non-magnetic cylindrical seal ring press-fitted and welded to the outer circumference of one end on the nozzle body side of the fixed core and the inner circumference of one end of the nozzle body. The inner circumference of the fuel swirler and the inner circumference of the seal ring function serve as a guide for slidably guiding a stroke movement of the needle. The fuel swirler is held between the receiving surface of the nozzle body and the orifice plate, thus defining an annular fuel passage between the outer circumference of the fuel swirler and the inner circumference of the nozzle body, so that fuel flows into a passage groove formed at the lower end surface of the fuel swirler via the annular fuel passage.
