Patent number: 10717369Abstract: A charge control apparatus for an electric vehicle that includes: a traction motor; a traction battery to which charging current is supplied from an external power source and that supplies current to the traction motor; and an electric device actuated by part of the charging current during charging of the traction battery is provided. The charge control apparatus includes: an instruction unit to instruct decrease of load of the electric device in case that the electric device is actuated during charging of the traction battery; a restriction unit to restrict the charging current after instruction of the decrease of load; and a load decreasing unit for decreasing load of the electric device after restricting the charging current.Type: GrantFiled: August 16, 2017Date of Patent: July 21, 2020Assignee: MITSUBISHI JIDOSHA KOGYO KABUSHIKI KAISHAInventors: Kazuya Koike, Shinya Fujiwara, Norihiko Hatsumi, Koichi Tano

Patent number: 8061313Abstract: A variable valve device is constructed to prevent inclination of a sliding surface of a high speed rocker arm. In an engagement surface where a connecting pin and the engagement portion of a high speed rocker arm are in contact, the center of the width of the surface in the direction of the cam shaft is provided closer to the high speed rocker arm than the center of the width in the direction of the camshaft of a cam contact surface where the high speed cam and the sliding surface of the high speed rocker arm are in contact. The low speed rocker arm includes a cam receiver and a connecting portion. The width of the connecting portion is larger than that of the cam receiver. The side surface of the connecting portion projects beyond the side surface of the cam receiver. The high speed rocker arm includes a cam receiver and a connecting portion.Type: GrantFiled: February 18, 2009Date of Patent: November 22, 2011Assignee: Yamaha Hatsudoki Kabushiki KaishaInventors: Toshihiko Takahashi, Kazuya Koike

Patent number: 8033256Abstract: An engine having a variable valve mechanism arranged to switch a lift degree of a valve between a low speed state and a high speed state includes a cam carrier defined by a cam bearing portion, a rocker shaft support, and a hydraulic cylinder support. The cam bearing portion is provided on a line passing through the bore center of a cylinder in a plane perpendicular or substantially perpendicular to the camshaft. The low speed rocker arm swings in response to the low speed cam of the camshaft. The high speed rocker arm swings in response to the high speed cam of the camshaft. The low speed rocker arm includes a through hole. A connecting pin is slidably inserted into the through hole and urged toward the hydraulic cylinder support. A hydraulic cylinder is provided in the hydraulic cylinder support.Type: GrantFiled: February 18, 2009Date of Patent: October 11, 2011Assignee: Yamaha Hatsudoki Kabushiki KaishaInventors: Toshihiko Takahashi, Kazuya Koike
