摘要： The present invention is for providing an oil-impregnant sintered bearing, which can reliably preserve an oil film on a sliding face, and a method for manufacturing the oil-impregnant sintered bearing. An oil-impregnant sintered bearing is made by providing an internal diameter, which a rotating axis member is inserted through, in a bearing main body, formed by a porous sintered alloy having internal pores therein, and providing a sliding face in one region of the inner peripheral face of the internal diameter, the sliding face being obtained by closing the pores which have been opened in the inner peripheral face. The density in a section preserving oil pressure, which extends from the sliding face of the bearing main body toward the outer side of the diameter, is made higher than the density in other sections of the bearing main body.

摘要： A motor controller is provided with: an estimated temperature calculating means that calculates an estimated temperature of a motor; and a control unit that can perform a driving control of the motor only when the estimated temperature is not larger than a predetermined value. A mode switching means switches the control unit and the estimated temperature calculating means between in a normal operation mode in which they can drive the motor and in a sleep mode in which electric power consumption thereof is smaller than in the normal operation mode in accordance with a predetermined condition while the motor is stationary. An activating means activates the estimated temperature calculating means in the sleep mode for a predetermined active time every time a predetermined sleep time is elapsed.
