摘要： PURPOSE:To enable measurement of a torque quickly and accurately as transmitted through a rotary magnetic body, by measuring the mean of torques transmitted through a rotary magnetic body at each inflection point section without being affected by offset components. CONSTITUTION:A symmetrical AC waveform voltage is applied to an exciting coil 16 of a magnetic sensor 12 through an AC amplifier 32 to alternately magnetize a rotating shaft and a distortion generated in the rotating shaft is detected 20 as electromotive force. The resulting detection signal is inputted 46 through an amplifier 34, a detector 36 and an A/D converter 38. An angle of rotation of the rotating shaft is also detected 42 and a timing signal therefore is inputted into the converter 38, an arithmetic unit 40 and a memory 44. Then, the converter 38 converts a rectified detection signal Si into digital from analog as outputted 36 each time a first timing signal is inputted from a generator 42 and outputs it to the arithmetic unit 40. Then, a subtractor 48 substracts an output signal Gj the memory 44 from an output signal Fj of a totalized 46 on the basis of first and second timing signals outputted 42 and the subtracted value Ej is sampled and held 50 to be outputted at each channel.

摘要： PROBLEM TO BE SOLVED: To restrict any initial discharge capacity drop from taking place so as to enable charging/discharging cycle characteristics to be improved, by using a composition formed by means of replaced introduction of Li in a part of Mn sites as well as making replaced introduction of a metallic element of a specific valence in a part of Li sites of LiMn compound oxide of spinal type crystal structure. SOLUTION: As a composition, (Li1-x Mx )8a [Liy Mn2-y ]16c O4 is used. Here, if the metal M subject to replaced introduction to Li site is monovalent metallic element, Li site valence is invariant without any replacement effect, and in the case of more than tetravalent, difference from Li ion is excessively large and replaced introduction to Li site is difficult and crystal structure becomes unstable, therefore bivalent or trivalent metallic element is employed. Therefore, as a metallic element M, Zn, Ga, In, etc., have diameters not so much different from the diameter of Li ion, they are liable to be configured in a tetrahedron sites, and without giving any strain to a crystal lattice, crystal structure is stabilized, no breakage of the lattice can happen even though charging/discharging are repeated so as to enable improvement in charging/discharging characteristics.
