Patent number: 6467471Abstract: Even when a reaction delay time of an A/F ratio detection device changes, an A/F ratio controller prevents an A/F ratio feedback control from being disturbed. The controller is programmed to calculate an A/F ratio feedback coefficient by proportional term control and integration term control, and to set length of time for said integration term to be carried out in accordance with an operating state of the engine. It is programmed to calculate the integration term based on the set time and to set a proportional term for shifting said A/F ratio feedback coefficient. It is further programmed to detect a deviation between a first A/F ratio feedback coefficient before the integration term is carried out and a second A/F ratio feedback coefficient after the integration term is carried out and the coefficient is shifted by the proportional term set by said means for setting the proportional term. Based on the detected deviation, the length of time for the integration term to be carried out is corrected.Type: GrantFiled: December 14, 2000Date of Patent: October 22, 2002Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Masayuki Wakui, Wataru Inagawa

Patent number: 6467456Abstract: An engine ignition timing control system for outboard motor having a propeller connected to the engine to be rotated and mounted on a boat such that the boat is propelled forward or backward. The engine is equipped with a decompression mechanism and is started by a recoil starter. In the system, at the time of engine starting, the ignition timing is set to a predetermined crank angle until the detected engine speed exceeds a first prescribed engine speed, while it is set to a value obtained by retrieving a table by at least the detected engine speed after the detected engine speed exceeds the first prescribed engine speed. And, the ignition timing is advanced until the detected engine speed is equal to or greater than a second prescribed value and is then returned to the retrieved value. With this, the engine speed can be reliably increased at starting, without need for a throttle opener or air-fuel ratio enrichment, thereby enhancing engine starting performance.Type: GrantFiled: May 16, 2001Date of Patent: October 22, 2002Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Sadafumi Shidara, Kazuhiro Satoh

Patent number: 6464176Abstract: A flap mounted on a tapered main wing of an aircraft, is supported by at least two link units. The link units are formed into analogous shapes with an analogous size ratio equal to the ratio between corresponding chord lengths of the main wing. As a result, the amounts of protrusion of the flap are varied in the span direction in accordance with the analogous size ratio, and the flap performs a three-dimensional motion such that it is moved in the span direction while being retracted and lowered. Thus, the flap can be moved to protrude to an optimal position and through an optimal angle according to the chord lengths of the main wing. When the flap is a slotted flap, an appropriate slot width can be ensured at each of the portions in the span direction, whereby the aerodynamic characteristic of the flap mounted on the tapered main wing can be uniform in the span direction.Type: GrantFiled: July 25, 2001Date of Patent: October 15, 2002Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Minoru Uchida, Hiroshi Yamanouchi, Wataru Yada, Hidetaka Nagano

Patent number: 6464175Abstract: A flaperon operating device having a center pulley and a slider supported on a center shaft. When the center pulley and the slider are rotated about the center shaft, left and right driving pulleys are rotated in the same direction, whereby left and right flaperons are operated in opposite directions to provide aileron functions. When the slider is slid rearwards on the center shaft by an actuator, the left and right driving pulleys are rotated in opposite directions, whereby both the left and right flaperons are lowered to provide flap functions. If the left and right flaperons are lifted or lowered by a very small angle in the same phase by the actuator, boundary layers on main wings can be controlled to reduce the drag.Type: GrantFiled: July 13, 2001Date of Patent: October 15, 2002Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Wataru Yada, Hiroshi Yamanouchi, Minoru Uchida, Katsutoshi Tada

Patent number: 6464145Abstract: An IC card produces electric power by rectifying a high-frequency signal received from a reader/writer. A MOS transistor is connected to an antenna and the received signal is rectified by the parasitic diode of the MOS transistor. The capacitance accompanying the transistor is added to the capacitance of an input tuning capacitor. Switching the on/off state of the transistor causes the capacitance added to that of the tuning capacitor to change; accordingly, the input tuning frequency changes and the relation between the input tuning frequency and the frequency of the received high-frequency signal changes. As a result, the amplitude of the received high-frequency signal changes and thus the obtained power also changes.Type: GrantFiled: May 4, 2000Date of Patent: October 15, 2002Assignee: Rohm Co., Ltd.Inventor: Shigemi Chimura
