The present invention provides an active material which can increase the discharge capacity of a lithium-ion secondary battery as compared with the case using conventional LiMnPO4 as a positive electrode active material. The active material in accordance with the present invention contains a crystallite of LiMnPO4, the crystallite having a size of 20 to 93 nm in a direction perpendicular to a (060) plane thereof.

A method for effecting a measurement of the unbalance of a small weight rotor body such as a impeller or turbine wheel for a turbo-charger in an internal combustion engine. A shaft, on which the rotor body is inserted and which is on both ends thereof supported on a pair of bearing units, is rotated while the rotor body is held on the shaft under an elastic frictional force. The unbalance is at every angular position of the rotor body measured during the rotation of the shaft.
