Publication number: 20240068833Abstract: A vehicle display device includes a display that is mounted on a vehicle and superimposes and displays an image on a real landscape in front with respect to a front windshield, a controller that controls the display, and a position information acquisition unit that acquires a position of a preceding vehicle. The controller calculates a first virtual straight line that connects the position of the preceding vehicle and a position of the vehicle. When the controller determines that the first virtual straight line is along a straight direction of the vehicle, the controller displays a marker image at a position below the preceding vehicle. When the controller determines that the first virtual straight line is inclined with respect to the straight direction, the controller performs display movement control to display the marker image so as to be shifted from the position below the preceding vehicle.Type: ApplicationFiled: August 22, 2023Publication date: February 29, 2024Inventors: Kazuyoshi Ogasawara, Takenobu Tomihira, Hiroki Kitahara

Patent number: 7070173Abstract: An apparatus for adjusting the air-fuel ratio of a fuel mixture to be supplied to an engine. The apparatus has a pair of needle valve bodies and a pair of receptacles formed in a main body of a carburetor for receiving the needle valve bodies. Each needle valve body has a needle and a head. The needles are axially movable relative to a respective needle orifice. The needles may be axially advanced and retracted by rotating the needle valve bodies within the receptacles to respectively decrease and increase the flow of the fuel mixture around the needles and through the orifices. To prevent tampering with the needle valve body setting, the head of the needle valve body has an unconventional shape requiring a specialized tool to rotatably adjust the needle valve body. To further prevent tampering, the head is recessed with the main body of the carburetor.Type: GrantFiled: June 30, 2005Date of Patent: July 4, 2006Assignee: Walbro Engine Management, L.L.C.Inventors: Paul J. Dow, Hiroki Ogasawara, Tetsuya Takahashi, Toshimasa Takahashi, Giovanni Vimercati

Patent number: 6481699Abstract: An acceleration device of a carburetor for a two cycle engine with a rotary dual valve which controls air flow through both a scavenging passage and a separate air intake passage each extending through a carburetor body. The carburetor body houses a metering fuel chamber and an air reference chamber defined by a diaphragm between them. Fuel in the metering fuel chamber is discharged through a port into the air intake passage. An acceleration pump has an actuation chamber which communicates with the scavenging passage and a pump chamber which communicates with the air reference chamber and a membrane between them. During engine acceleration the membrane is displaced by a pressure introduced into the actuation chamber to forcibly send air into the air reference chamber from the pump chamber to move, the diaphragm into the metering fuel chamber, and thereby increase the fuel delivered to the air intake passage.Type: GrantFiled: October 16, 2000Date of Patent: November 19, 2002Assignee: Walbro Japan, Inc.Inventors: Tamio Aihara, Hiroki Ogasawara

Patent number: 6382599Abstract: A circuit for delivering fuel into a valve chamber of a rotary throttle valve type carburetor. The fuel delivery circuit includes a fuel supply nozzle, protruding into the valve chamber and fixed at the bottom of the valve chamber to the carburetor body, and an intermediate wall. The intermediate wall is connected to the bottom of the carburetor body. The intermediate wall has a first chamber defined therein, a second chamber defined therein, and structure which cooperatively defines a first passage and a second passage therein. The first passage communicates the first chamber to the fixed end of the fuel supply nozzle, and the second passage communicates the second chamber to the first chamber. In addition, the fuel delivery circuit also includes an enclosure having a pressurized fuel chamber disposed under the intermediate wall, wherein the intermediate wall cooperatively defines a third passage that communicates the pressurized fuel chamber to the second chamber.Type: GrantFiled: August 1, 2000Date of Patent: May 7, 2002Assignee: Walbro Japan, Inc.Inventors: Tamio Aihara, Hiroki Ogasawara
