Patent number: 9776636Abstract: A calculation method and apparatus for calculating a starting point for acceleration/deceleration operation of a vehicle with high accuracy using more input values while at the same time keeping calculation cost and time to a minimum is disclosed herein. An ECU making up a system calculates a start point for acceleration/deceleration operation of a vehicle on the basis of traveling condition information that changes as the vehicle travels and vehicle information that changes only slightly as a result of the travel of the vehicle. As a result, if the driver maintains a throttle operator at a given opening angle or more at a point before the start point, an actuator applies a force in the direction of closing a throttle valve to the throttle operator, thereby notifying the driver that the vehicle is close to the start point.Type: GrantFiled: September 28, 2015Date of Patent: October 3, 2017Assignee: Honda Motor Co., Ltd.Inventors: Yamato Nakamizo, Tetsuya Kudo, Toraki Iwamaru, Satoshi Fukuoka, Takao Fujiwara, Masatoshi Sato

Patent number: 5970613Abstract: A tappet made of Al alloy is used in a valve operating mechanism of an internal combustion engine of a vehicle. On the whole outer circumferential surface of the tappet, a helical projection and a helical groove are formed alternately to form an uneven surface. A plurality of uneven surfaces are formed on a ridge of the projection at regular intervals. The outer circumferential surface is coated with a wear resistant Fe film by thermal spraying. The uneven surfaces on the projection provide high adhesion strength of the film to the outer circumferential surface of the tappet to improve peel resistance, thereby increasing durability and reliability of the Al alloy tappet.Type: GrantFiled: June 15, 1998Date of Patent: October 26, 1999Assignee: Fuji Oozx Inc.Inventors: Akiyoshi Mori, Nobuo Hara, Satoshi Fukuoka, Tatsuo Kanzaki

Patent number: 5918366Abstract: An Al alloy tappet used in an internal combustion engine has a spiral groove on the outer circumferential surface of a tappet body. The spiral groove is formed by pushing a cutting tool against the outer circumferential surface and feeding it in an axial direction. Near the lower end of the tappet body, feed rate is decreased, and the cutting tool is moved away from the tappet body to form a smaller spiral groove which increases in diameter downwards. The outer circumferential surface of the tappet body is covered with a coating layer such as Fe, and the lower end which has the smaller spiral groove is chamfered.Type: GrantFiled: August 28, 1997Date of Patent: July 6, 1999Assignee: Funi Oozx Inc.Inventors: Akiyoshi Mori, Satoshi Fukuoka, Tatsuo Kanzaki
