摘要:
A roller 58 is rotatably held by an end portion of an eccentric support roller shaft 50 so that the roller 58 contacts with an inner periphery circular side surface of a rotor 40. Accordingly, a rotational resistance while the rotor 40 is eccentrically rotated can be decreased in comparison with a configuration in which an internal gear formed in an inner periphery of a rotor and an external gear formed in an eccentric shaft interlock each other. Thus, the rotating shaft 52 can be efficiently driven to rotate when a pressure difference is small and energy for rotating the roller 58 is small.

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.

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.

摘要:
A noncrystalline composite alkali metal titanate composition which is chemically stable, outstanding in resistance to hygroscopicity and suited as base materials for friction materials. The said composition comprises at least 60 wt. % of an alkali metal titanate represented by the general formula M2O.nTiO2 wherein M is one or at least two alkali metal elements and n is a number of 1 to 4, and at least 10 wt. % of SiO2, M2O/SiO2 being equal to or less than 2.5. When desired, it is possible to incorporate into the composition an oxide of at least one element selected from the group consisting of B, Mg, Al, P, Ca and Zn, and/or an oxide of at least one element selected from the group consisting of V, Cr, Mn, Fe, Co, Ni, Cu, Y, Zr, Nb and Ba.

An electric power steering apparatus includes a steering assisting electric motor having a motor housing for accommodating an annular rotor and an annular stator. The rotor and the stator are disposed coaxially with a steering shaft. The motor housing is supported by a support member mounted to a vehicle body member. A shock applied to a steering member when the motor vehicle crashes is absorbed by the relative movement between the motor housing and the support member.
摘要:
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.
