Patent number: 7642745Abstract: An apparatus capable of charging a battery mounted on a robot while allowing the robot to remain stably still in the state of standing on its legs is provided. Driving a first connector backward while it is connected with a second connector would cause a body of the robot to tilt as if being pulled by the first connector. However, it is possible to prevent the posture of the robot from becoming unstable by utilizing the fact that the connected state of first signal terminals and second signal terminals is maintained in that state. The backward driving of the first connector is restricted when a charge control unit is capable of communicating with a control system via the first signal terminals and the second signal terminals. This prevents the undesirable event that the posture of the robot becomes unstable due to the first connector being driven backward unconditionally.Type: GrantFiled: March 31, 2008Date of Patent: January 5, 2010Assignee: Honda Motor Co., Ltd.Inventors: Satoshi Kaneko, Koji Okazaki, Norio Neki, Hiroyuki Makino, Takashi Nakayama, Masaaki Muromachi

Patent number: 7406911Abstract: An expander (M) employing steam as a working medium is formed from a first radially inner group of axial piston cylinders (49) arranged annularly on a rotor (27) so as to surround the axis (L) of an output shaft (28), and a second radially outer group of axial piston cylinders (57) arranged annularly so as to surround the first group of axial piston cylinders (49). The first and second groups of axial piston cylinders (49, 57) are driven by a common swash plate (39), and the first and second groups of axial piston cylinders (49, 57) are arranged with circumferentially displaced pitches. High-temperature, high-pressure steam firstly operates the first group of axial piston cylinders (49), then operates the second group of axial piston cylinders (57), and the outputs from the two are combined to drive the output shaft (28). This achieves a further reduction in the size and a further increase in the output of the axial type expander (M).Type: GrantFiled: March 5, 2002Date of Patent: August 5, 2008Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Makoto Uda, Hiroyuki Makino, Kouhei Ohsono

Publication number: 20060153698Abstract: A rotary fluid machine is provided in which, among first bearings (23f, 23r) and a second bearing (24) supporting in a casing (11) opposite ends of a rotor (22) that includes an axial piston cylinder group (56) for converting the pressure energy of a working medium into mechanical energy, only the first bearings (23f, 23r) are formed from combined angular bearings that can support an axial load, and the second bearing (24) is formed from a radial bearing that can support a radial load and is axially movable relative to the rotor (22). Since the rotor (22) is axially positioned relative to the casing (11) by only the first bearings (the combined angular bearings) (23f, 23r), a difference in the amount of axial thermal expansion between the casing (11) and the rotor (22) can be absorbed by the second bearing (radial bearing) (24) without any problem. This can solve effectively problems caused by a difference in the amount of thermal expansion between the casing and the rotor of the rotary fluid machine.Type: ApplicationFiled: December 22, 2003Publication date: July 13, 2006Inventors: Hiroyuki Makino, Kensuke Honma, Yasuharu Kamoi

Publication number: 20050254965Abstract: An expander is provided in which spherical projections (61a) formed at the forward end of pistons (42) of an axial piston cylinder group abut against spherical depressions (31a) formed in a swash plate (31), and an elliptical contact point locus (T) of contact points (p) between the spherical depressions (31a) and the spherical projections (61a) is offset toward the expansion stroke side of the axial piston cylinder group. As a result, in a middle region of the expansion stroke where the speed of the piston (42) is high and the surface pressure of the contact point (p) is high, the position of the contact point (p) can be made as close as possible to an axis (L3) of the spherical depression (31a) and an axis (L2) of the piston (42), thus reducing a bending moment and a radially biased load exerted on the piston (42) and minimizing any increase in sliding resistance and any occurrence of abnormal wear.Type: ApplicationFiled: June 20, 2003Publication date: November 17, 2005Applicant: HONDA GIKEN KOGYO KABUSHIKI KAISHAInventors: Hiroyuki Makino, Kohei Oosono

Publication number: 20040216602Abstract: A rotary valve of a rotating fluid machine is constructed by bringing into contact, on sliding faces which are orthogonal to an axis, a moving valve plate provided on a rotor and a stationary valve plate provided on a valve body. An annular member pivotably supports the valve body by a fulcrum shaft. The annular member has a pair of projections at its two ends. The pair of projections are engaged slidably in the direction of the axis with a pair of guide grooves formed in a rear cover. When the valve body is pressed in the direction of the axis to bring the sliding faces into close contact with each other, the pair of projections receive a uniform frictional resistance from the guide grooves, so that the annular member is prevented from inclining off a plane orthogonal to the axis. Therefore, the compliance of the sliding faces can be secured to prevent a working medium from leaking and to suppress uneven wear of the sliding faces.Type: ApplicationFiled: February 2, 2004Publication date: November 4, 2004Inventors: Kenji Matsumoto, Naoki Itoh, Hiroyuki Makino

Publication number: 20040200350Abstract: An expander includes a rotor rotatably supported by a casing, a group of axial pistons and cylinders installed so that its axis is surrounded by the rotor, and a swash plate having a rotating surface inclined with respect to the axis of the rotor and is rotatably supported by the casing. The relative rotation of the swash plate and the rotor around the axis is restricted and the relative shifting of the swash plate and rotor in the direction of the axis is allowed, by fitting a slider, fixed to the swash plate by a synchro-pin, into a long hole of an output shaft. Therefore, it is possible to prevent wrenching between the swash plate and the rotor due to thermal expansion while reducing the bending moment acting on the pistons of the group of axial pistons and cylinders of the expander.Type: ApplicationFiled: January 13, 2004Publication date: October 14, 2004Inventors: Hiroyuki Makino, Naoki Ohta, Kensuke Honma
