20090152044 | Steering apparatus for vehicle - A steering apparatus for a vehicle capable of executing a steer-by-wire (SBW) mode of steering road wheels by a steering mechanism mechanically disconnected with a steering device. The steering apparatus includes a clutch which is composed of a shaft rotated together with the steering device, an internal gear ring which has a rotation center coincide with that of the shaft and transmits its rotation to the steering mechanism, an external gear ring partially intermeshed with the internal gear ring, lock members which transmit/disconnect the rotation of the shaft to the external gear, and a lock operating member for displacing the lock members to lock/unlock positions. | 06-18-2009 |
20090260913 | Steering apparatus for vehicle - A steering apparatus for a vehicle capable of executing a steer-by-wire (SBW) mode in which road wheels are steered by a steering mechanism mechanically disconnected with a steering device. The steering apparatus comprises: a connecting mechanism which can connect the steering device and the steering mechanism mechanically; and an SBW control unit which sets the connecting mechanism to a disconnected state to control the steering mechanism based on an operating amount of the steering device under the steer-by-wire mode, and sets the connecting mechanism to a connected state to switch a steering mode from the steer-by-wire mode to a steer-by-wire backup mode when it has been determined that the steer-by-wire mode cannot be executed properly. The connecting mechanism is set to the disconnected state while being energized and set to the connected state while being non-energized. The SBW control unit checks whether or not the steer-by-wire mode can be executed properly at start of engine and always during operation of engine. Therefore, an SBW backup system can be activated unfailingly when the system is out of order. | 10-22-2009 |

20080264068 | Magnetic Convection Heat Circulation Pump - A magnetic convection heat circulation pump, wherein magnets are disposed inside a magnetic field flow passage for passing a magnetic fluid therein or on a part of the inner wall surface of a circulation flow passage in a magnetic pump thermally joined to a heat receiving part. The magnetic fluid is driven since a magnetic force is directly applied to the magnetic fluid and a large temperature gradient is produced between the heat receiving part and the magnetic pump due to a difference between a heat quantity transferred from the heat receiving part indirectly to the magnetic pump and the heat quantity of the magnetic fluid led into the magnetic pump. | 10-30-2008 |
20080277100 | Heat Transfer Apparatus of a Forced Convection Type - A forced convection heat transfer apparatus wherein a large quantity of heat can be efficiently transferred even when a temperature difference is small, by transmitting power to a magnet, which is rotatable along a circulation flow path of a magnetic fluid, and obtaining a magnetic fluid circulation speed in proportion to the rotating speed. | 11-13-2008 |
20090139227 | ROTARY HEAT ENGINE - A rotary heat engine having a cylinder and a rotor having a rotating shaft rotatably placed in the cylinder. The cylinder has a heat receiving section for supplying heat to the inside of the cylinder and a heat radiating section for radiating heat from the inside. The engine also has an engine section body and an operation liquid storage section. A vaporized gas supply channel and a gas recovery channel communicating with the inside of the cylinder are provided, respectively, on the heat receiving section side and heat radiating section side of the cylinder in the engine section body. The operation liquid storage section is between the vaporized gas supply channel and the gas collection channel in order to aggregate and liquefy recovered gas and is installed such that both channels fluidly communicate with each other. Also, the operation liquid storage section has a heat insulation dam provided with a through hole for preventing backflow of fluid flowing inside. | 06-04-2009 |

20080272582 | ENERGY ABSORBING STEERING SYSTEM - In an energy absorbing steering system including a steering shaft to which a steering member is coupled, and a steering column that rotatably supports the steering shaft, at least one of the steering shaft and the steering column includes an impact absorbing portion that contracts when a load equal to or higher than a predetermined value is applied, and the impact absorbing portion includes a first impact absorbing portion having a first impact absorption load, and a second impact absorbing portion having a second impact absorption load different from the first impact absorption load. | 11-06-2008 |
20080277193 | ELECTRIC POWER STEERING DEVICE - A steering shaft is composed of an upper shaft, a lower shaft, an input shaft, and an output shaft. The upper shaft, the lower shaft, and the input shaft can rotate together, and the input shaft and the output shaft are relatively rotatably coupled to each other via a torsion bar. The rotational position of a rotor coupled to the output shaft is calculated based on the detected rotational position of the lower shaft and a steering torque detected based on the amount of relative rotational displacement of the input shaft and the output shaft. Thus, it is not necessary to include a rotor rotational position detecting unit for detecting the rotational position of the rotor within the electric motor, which reduces the size of the electric motor. | 11-13-2008 |

The facing area between the stator and the rotor can be increased by providing the inner rotor and the outer rotor in the electric motor. Consequently, the electric motor can be miniaturized while a certain output thereof is maintained. The vehicle steering apparatus can be miniaturized by miniaturizing the electric motor. | 11-20-2008 |
