Patent number: 7335087Abstract: An eyeglass lens processing apparatus includes: a controller that controls a second driver for rotating lens chucks for chucking an eyeglass lens and a third driver for changing an axis-to-axis distance between an axis of a processing tool and an axis of the lens chucks so that a processing load falls below an allowable value; and a processing mode selector that selects one of a first processing mode in which the allowable value is set to be high, and a second processing mode in which the allowable value is set to be low so as to suppress axis deviation when the lens having a surface slipping readily is processed. The controller controls the first driver so that a second chucking pressure of the lens chucks when the second processing mode is selected is smaller than a first chucking pressure of the lens chucks when the first processing mode is selected.Type: GrantFiled: November 30, 2006Date of Patent: February 26, 2008Assignee: Nidek Co., Ltd.Inventors: Motoshi Tanaka, Yoichi Sugiura

Patent number: 6401691Abstract: A damping chamber is formed in a pressure relaxation device connected to a high pressure fuel pipe. Valve bodies are provided at openings of partitions, and a spring force is applied to the valve bodies by a spring in a valve closing direction. When a high pressure portion reaches an inlet of the damping chamber, the valve body opens to hold and absorb the high pressure portion in the damping chamber. When a low pressure portion reaches the inlet of the damping chamber, the high pressure portion held in the damping chamber is gradually released via a restricted orifice to cancel the low pressure portion, thereby reducing the pressure pulsation of fuel.Type: GrantFiled: October 22, 1999Date of Patent: June 11, 2002Assignees: Nippon Soken, Inc., Toyota Jidosha Kabushiki KaishaInventors: Takanobu Kawano, Tohru Yoshinaga, Katsuyuki Tanaka, Kenji Kanehara, Yoshihiro Nakase, Masaki Takeyama, Yoichi Sugiura, Katsuhiko Aoyama, Toshio Imamura

Patent number: 4543634Abstract: An ignition timing control system for controlling a fuel injection flow rate and an ignition timing commensurate to an intake air flow rate and an engine rotational speed. The ignition timing is controlled to the maximum permissible ignition advance angle when a throttle valve is fully closed and the fuel injection is stopped, for example, during deceleration, and thereafter, the ignition timing is controlled to the optimum ignition advance angle commensurate to an engine rotational speed upon return to the fuel injection.Type: GrantFiled: August 12, 1982Date of Patent: September 24, 1985Assignee: Toyota Jidosha Kabushiki KaishaInventors: Nobuyuki Kobayashi, Hiroshi Ito, Yoichi Sugiura
