摘要:
A noble metal catalyst powder produced by using co-precipitation method is made of noble metal alloy particles containing Pa, Pd, and Rh. The noble metal alloy particles have an average particle size within a range of 0.2 μm to 2.0 μm. A standard deviation in content of each of Pa, Pd, and Rh is not more than 20 mass %. This standard deviation in content of each of Pa, Pd, and Rh is detected at not less than ten detection-points of the noble metal catalyst powder by quantitative elemental analysis. A gas sensor element has the noble metal catalyst powder. An A/F sensor is equipped with the gas sensor element using the noble metal catalyst powder.

摘要:
To realize an anisotropic bonded magnet that reduces cogging torque without lowering output torque.The present invention provides a hollow cylindrically shaped anisotropic bonded magnet for use in a 4-pole motor, formed by molding anisotropic rare-earth magnet powder with resin. The alignment distribution of the anisotropic rare-earth magnet powder in a cross section perpendicular to the axis of the anisotropic bonded magnet is in the normalized direction of the cylindrical side of the hollow cylindrical shape in the main region of a polar period, and in a transition region in which the direction of the magnetic pole changes, steadily points towards a direction tangential to the periphery of the cylindrical side at points closer to the neutral point of the magnetic pole, and becomes a direction tangential to the periphery of the cylindrical side at that neutral point, and steadily points toward the normalized direction of the cylindrical side at points farther away from the neutral point.

摘要:
In a case where one of a left and right pair of drive wheels is a non-controlled wheel to which braking force of a vehicle behavior control is not applied, and the other of the drive wheels is a controlled wheel to which braking force is applied, a detected vehicle wheel speed for the non-controlled wheel is corrected to a smaller value in accordance with increase in the roll angle, and increase in the braking force of the controlled wheel when a roll angle of a vehicle body is larger than a threshold value. In a vehicle behavior control, when lateral G acts upon the vehicle during turning, braking force is applied to the controlled wheel that is at the outside of the turn. This braking force application causes driving force of the controlled wheel to be partially transferred to the non-corrected wheel that is at the inside of the turn, whereby the vehicle wheel speed of the non-corrected wheel is increased. Accordingly, in the present invention, correction calculation is performed.
