Abstract: A deterioration diagnosis unit of an arithmetic unit constituting a remaining performance evaluation system diagnoses the deterioration degree of a secondary battery that has already been used for primary use based on an actual measurement value. The deterioration speed update unit updates the deterioration speed of the secondary battery based on the diagnosis result of the secondary battery. The remaining performance estimation unit estimates the remaining performance of the secondary battery after the start of secondary use based on the updated deterioration speed and a usage method at the time of the secondary use of the secondary battery.

Abstract: A lens barrel 10 comprises fourth lenses L4a and L4b, a substantially cylindrical fourth lens group unit 20, and a substantially cylindrical cam frame 14. The fourth lens group unit 20 holds the fourth lenses L4a and L4b and has a plurality of cam pins 22a to 22c and 23 protruding in the radial direction. The cam frame 14 is disposed substantially coaxially with the fourth lens group unit 20, and has a plurality of cam grooves 14c that are formed in a direction intersecting the optical axis direction and engage with the cam pins 22a to 22c and 23; assembly grooves 14d and 14f that are provided contiguously with the cam groove 14c, engage with the cam pins 22a to 22c and 23 in the mounting and assembly of the fourth lens group unit 20, and guide these cam pins from the end portion to the cam groove 14c in the optical axis direction; and a concave portion 14g that holds the cam pin 23 in the assembly groove 14f in the assembly of the fourth lens group unit 20.

Abstract: An arc welding control method is for performing control in an arc period. The control includes: (i) increasing a welding current to a first current value at a first gradient and maintaining the welding current at the first current value for a first period; (ii) reducing the welding current from the first current value to a second current value at a second gradient and maintaining the welding current at the second current value for a second period; (iii) increasing the welding current from the second current value to a third current value at a third gradient; and (iv) starting to reduce the welding current from the third current value within a third period, which is shorter than the first period, after the welding current reaches the third current value.

Abstract: An alkaline dry battery includes a positive electrode, a negative electrode, and a separator disposed between the positive electrode and the negative electrode. The positive electrode contains electrolyte and the negative electrode contains electrolyte. The positive electrode further contains electrolytic manganese dioxide, sodium, and zinc. The electrical potential of the electrolytic manganese dioxide is 300 mV or higher and 340 mV or lower with respect to that of a reference electrode made of mercury oxide. The content of the sodium in the positive electrode is 800 ppm by mass or more and 3000 ppm by mass or less. The content of the zinc in the positive electrode is 2400 ppm by mass or more and 4600 ppm by mass or less.
