Abstract: An information processing method for use in a computer includes: acquiring a charging state and a deterioration state of a battery; determining an upper limit of the charging state of the battery based on the deterioration state; determining a charging plan of the battery based on the upper limit of the charging state determined and the charging state; and outputting the charging plan determined.

Abstract: An Ni-based alloy solid wire for welding has a composition comprising specific amounts of Cr, Ti, Nb, C, S, Mn and Fe, where Mo+W, P, Si, Al, Ca, B, Mg, Zr, Co, O, H, and N are controlled to specific amounts, ([Ti]+[Nb])/[C] is 80 to 150, and the balance is Ni and inevitable impurities. [Ti], [Nb], and [C] represent the contents of Ti, Nb, and C (mass %), respectively.

Abstract: The contents of Cr, Fe, Mn, Ti, Si, Cu, N, Al, C, Mg, Mo, B, Zr, and Nb+Ta in a Ni-base alloy weld metal are properly specified and the contents of Co, P, and S in incidental impurities are controlled. In particular, a weld metal having high cracking resistance is formed by specifying the Mn content in a proper range and restricting the contents of B and Zr at low levels. Regarding a Ni-base alloy covered electrode, by specifying the contents of a slag-forming agent, a metal fluoride, and a carbonate serving as flux components in proper ranges and controlling the contents of Mn, Nb+Ta, and Fe in a flux, good welding workability is achieved and a weld metal having good bead appearance is formed.

Abstract: A flux-cored nickel-based alloy wire contains, based on the total mass of the wire, 3 to 11 percent by mass of TiO2, 0.2 to 1.3 percent by mass of SiO2, 1 to 3 percent by mass of ZrO2, and 0.3 to 1.0 percent by mass of manganese oxides in terms of MnO2, contains of a total of 0.2 to 1.0 percent by mass in terms of Na, K and Li of sodium compounds, potassium compounds, and lithium compounds. The flux has a ratio (([TiO2]+[ZrO2])/[SiO2]) of the total of the TiO2 and ZrO2 contents to the SiO2 content of 5.0 to 14.5, in which [TiO2], [SiO2] and [ZrO2] represent TiO2, SiO2 and ZrO2 contents. The wire shows excellent weldability in welding of all positions typically on 9% nickel steels and nickel-based alloy steels and gives a weld metal having good pitting resistance, bead appearance, and resistance to hot cracking.

Abstract: A process of core molding is disclosed, which permits increasing the positioning accuracy of a base core and a bonded core relative to each other and also avoids handling the first molded base core outside the die to preclude such trouble as breakage of the common die. By the process, a complete core is obtained, which comprises a base core and a bonded core positioned in and bonded to the base core. The base core is molded in a molding space which is defined by engaging a die element and a common die with each other. After removing the die element from the common die while leaving the molded base core in the common die, a different die element is engaged with the common die to define a different molding space for molding a bonded core. The bonded core is bonded to the base core as it is molded.
