  • Patent number: 6914694
    Abstract: A system for printing photos, or images generally, includes a server computer that stores data representing a plurality of images in a photo database. A server web interface enables communication over the Internet, and the server computer includes an image print application that enables images to be printed using a client computer connected to the server web interface over said Internet. The server computer also includes an image enhancement module that enhances an image for printing. In response to a print request (over the Internet) from the client computer, the server computer sends image data and the image enhancement module to the client computer. The server computer activates the image print application to create print commands for a printer driver, and to create enhanced image data in the client computer with the image enhancement module prior to printing. The enhanced image data is removed from the client computer immediately following printing.

  • Patent number: 6102000
    Abstract: A fuel injection apparatus for a diesel engine has a fuel injection pump for feeding fuel under pressure and fuel injection nozzles provided in the engine to inject fuel fed from the injection pump. A pressure sensor for detecting fuel pressure is provided in a midway in a fuel line connecting the injection pump to the injection nozzles. An electronic control unit (ECU) computes the frequency of the fuel pressure based on a detected value from the pressure sensor immediately after fuel is injected from the injection nozzles. The ECU then computes a fuel bulk modulus based on the result of the computation of the frequency of the fuel pressure. Based on the computed bulk modulus, the ECU computes a fuel injection start and end time. Further, the ECU adjusts an instruction value for fuel injection control based on the result of the computation of injection start and end, and controls the injection pump based on the adjusted instruction value.

  • Patent number: 6073537
    Abstract: A roller bush for a fuel injection pump is interposed between a metal roller and a pin. The roller is forced to contact with a cam reciprocating a plunger, and the pin supports the roller rotatably about a rotational axis at either axial side of the bush. Either axial end portions of the bush entirely consist of ceramic, each portions having the axial length from the corresponding axial end surface of L. The ratio of the axial length L to the entire axial length L0 of the bush is set to be equal to or larger than {(11-d)/16}, where d represents the inner diameter of the bush.
