摘要： A non-aqueous electrolyte secondary battery in which a positive electrode formed of a graphite powder and an negative electrode formed of a material capable of absorption/desorption of a lithium metal or lithium are placed to face each other in an electrolyte containing lithium salt. The positive electrode of this battery where a Lc (112) which is the size of crystallite in a c axis direction which is calculated from a (112) diffraction line of a graphite crystal and determined by a powder X-ray diffraction method which is from 4 nm to 30 nm, and a charge capacity at the first cycle which is calculated on the basis of a total weight of the graphite material of the positive electrode filled in the battery is 20 to 50 (mAh/g). Preferably, the graphite powder of the positive electrode has an ratio (A/B) which is the ratio of a specific surface area A determined by a nitrogen absorption (BET) method to a surface area B determined on the basis of an area average diameter of 20 or less.

摘要： A non-aqueous electrolyte secondary battery includes a positive electrode 11 made of graphite powder and a negative electrode 13 made of lithium metal or a lithium-intercalatable/deintercalatable material. The positive electrode 11 and the negative electrode 13 are faced to each other with an electrolyte, containing a lithium salt, interposed in between. The positive electrode 11 has a carbon-derived absorption peak which appears within a range of 3200 gauss to 3400 gauss in an electron spin resonance method in which measurement is performed using an X band. A relative ratio (ΔH40K/ΔH296K) of the full width of half maximum intensity ΔH40K of the peak measured at a temperature of 40 K to the full width of half maximum intensity ΔH296K of the peak measured at a temperature of 296 K is 2.1 or more. Accordingly, it is possible to provide the non-aqueous electrolyte secondary battery which prevents degradation of the capacity in charge/discharge cycles after performing high temperature floating charge.

摘要： A hydraulically driven traveling vehicle comprising a pair of right and left driving axles (driving sprockets) differentially connected to each other by a differential mechanism, the input section of the differential mechanism having the output rotation of traveling HST 110 (110) transmitted thereto, both driving sprockets having mutually opposite two-flow output rotations separately transmitted thereto from a steering HST (120), thereby effecting traveling driving and turning, electromagnetic solenoids (61a, 61b, 62a, 62b) serving as output regulating devices for the traveling HST and the steering HST being provided so that the manipulated variables and directions of a speed change lever and a steering operation tool are converted into electric signals, on the basis of which electric signals the output current values of the electromagnetic solenoids are controlled, causing the respective output rotary speeds of the HSTs to correspond to the output current values.
