Patent number: 11912160Abstract: In an inverter generator controller, residual charge of a battery is detected and generated power output is detected. Then, low-load charging of the battery is implemented if the detected generated power output of the engine generator unit is equal to or greater than the detected load output demand and the detected generated power output of the engine generator unit is less than the predetermined low-load value a, when the detected residual charge of the battery is equal to or less than the first threshold value. When the detected residual charge of the battery becomes greater than the first threshold value, the low-load charging of the battery is terminated.Type: GrantFiled: March 29, 2018Date of Patent: February 27, 2024Assignee: Honda Motor Co., Ltd.Inventors: Yukihiko Kiyohiro, Taiyo Onodera, Minoru Maedako

Patent number: 8695167Abstract: A work machine handle device having a foldable handle is disclosed. As the handle is to be changed from a folded-up state to a use state, the handle is turned about a frame as a turning fulcrum. An actuating protuberance provided integrally to a turning member of a clamp body is pushed by a handle engaging/disengaging part provided to a front end of the handle, and the turning member is caused to turn. The handle engaging/disengaging part is held from either side and automatically restrained by a clamp mechanism. When the handle is changed from the use state to the folded-up state, a restraining mechanism is operated to release the engagement between the restraining mechanism and a distal end of the turning member. The turning member is turned by a return force of a spring provided to the clamp body, the handle engaging/disengaging part ceases to be restrained, and the handle can be folded up.Type: GrantFiled: June 22, 2011Date of Patent: April 15, 2014Assignee: Honda Motor Co., Ltd.Inventors: Hiroshi Mizuguchi, Taiyo Onodera, Yosuke Toyohira

Patent number: 7513223Abstract: An engine-driven work machine is provided in which an engine/work machine unit (5) is housed in a box (30) and a cooling fan (15) for generating a flow of cooling air from an air inlet (39) to an air outlet (40) via the surroundings of the engine/work machine unit (5) is disposed within the box (30), wherein a gas/liquid separation chamber (32) for restricting the flow of cooling air is provided between the air inlet (39) and the engine/work machine unit (5), and the gas/liquid separation chamber (32) is provided with a first wall face (32a1) for changing upward flow of cooling air into a lateral direction after it has collided with the first wall face (32a1) and a second wall face (32a2) for changing the lateral direction of flow into an obliquely downward direction. This enables mist contained in cooling air taken into the box to be separated and removed effectively before the cooling air reaches the surroundings of the engine/generator unit.Type: GrantFiled: January 13, 2006Date of Patent: April 7, 2009Assignee: Honda Motor Co., Ltd.Inventors: Taiyo Onodera, Hitoshi Yuki
