A conductive lead 21 or 22 welded to a positive electrode 11 or a negative electrode 12 protrudes from the upper surface side and the lower surface side of an electrode group 10. The conductive leads 21 and 22 have spiral shape portions 21b and 22b and end portions 21c and 22c for welding, respectively. The end portion 21c for welding of the conductive lead 21 is welded to a lid unit 5, and the end portion 22c for welding of the conductive lead 22 is welded to a can bottom 203 of a battery can 2. The end portion 22c for welding of the conductive lead 22 is positioned corresponding to a hollow portion 15a of an axial core 15.
摘要:
In a charging control system for recording data regarding charging a secondary battery, a status recording unit refers the charging voltage value and the charging current value and records the referred charging voltage, the referred charging current and reference time when the charging current value is referred and time when the charging voltage value is referred, on the recording unit. A battery protecting unit stops the charging the secondary battery when the charging voltage exceeds the predetermined target voltage value. The status recording unit starts recording of the charging voltage value, the charging current value, and the reference time on the recording unit, when the charging voltage exceeds the target voltage value as a result of a fail in stopping the charging by the battery protecting unit because of occurrence of a trouble in the battery protecting unit.

A quantitative echo sounder includes delay circuits, phase correction circuits, an incidence angle calculator and a directivity correction unit. The delay circuits adjust transmission start timing or phases of acoustic waves radiated by individual vibrating elements based on pitch and roll angles measured by a motion sensing device so that the direction of an acoustic axis of a transmitting beam matches a sounding direction. The phase correction circuits adjust phases of received echo signals based on the pitch and roll angles so that the direction of an acoustic axis of a receiving beam matches the sounding direction. The incidence angle calculator calculates echo signal incidence angle with respect to the sounding direction from phase differences among receiving beam signals obtained by four vibrating element groups. The directivity correction unit corrects a measured target strength by using the echo signal incidence angle calculated by the incidence angle calculator.

A process for producing 2,6-dimethylnaphthalene by subjecting 2,7-dimethylnaphthalene to an isomerization reaction, wherein the isomerization reaction is carried out by the use of a metallosilicate catalyst that comprises a metallosilicate having a main cavity defined by a ten-oxygen-membered ring, that is in the form of aggregates of fine crystals of the metallosilicate, the external surface area of the aggregate as calculated from t-plot analysis made in the nitrogen adsorption method being 25 m2/g or more, and that has been treated to inactivate acid centers present on the external surfaces of the fine crystals until the rate constant basic value N becomes 0.5 or less.
摘要:
In order to provide a charge/discharge technology for controlling an assembled battery system without promoting degradation or reduction in the lifetime of the assembled battery system, the assembled battery system includes a function for controlling charge and discharge power of a plurality of units each including a secondary battery and a power converter as one unit, the plurality of units being electrically connected in parallel to each other. When each unit performs charge or discharge by at least one or more times, charge and discharge of the unit are controlled so as not to be performed until a predetermined pause time period elapses.
