Abstract: A solid-state battery that exhibits improved battery performance includes: a positive-electrode collector; a negative-electrode collector; a positive electrode layer formed on the positive-electrode collector and containing a positive-electrode active material and a solid electrolyte; a negative electrode layer formed on the negative-electrode collector and containing a negative-electrode active material and a solid electrolyte; and a solid electrolyte layer disposed between the positive electrode layer and the negative electrode layer and containing a solid electrolyte. At least one of the solid electrolyte and the solid electrolyte partly represents a porous solid electrolyte.

Abstract: A die cushion device includes four hydraulic cylinders that support a cushion pad, a die cushion load controller that controls each of the hydraulic cylinders and generates a die cushion load on the cushion pad, and a die cushion position controller that controls each of the hydraulic cylinders to control a position of the cushion pad. In a case where only a left part is produced with a left die by a press machine, the die cushion load controller performs die cushion load control on two hydraulic cylinders on the left side, and the die cushion position controller performs die cushion position control on two hydraulic cylinders on the right side.

Abstract: The die cushion force setting apparatus according to an aspect of the present invention allows die cushion forces (component forces) acting on plural driving shafts to be set easily, makes it easy to apply strong or weak die cushion forces to a complex-shaped drawn part in a plane of a cushion pad, and provides a smooth die cushion force distribution. An operator manually enters a total die cushion force, axial component force of a left front hydraulic cylinder, and center-of-force position by operating an input device. Based on the information entered via the input device, the numerical computing device B1 calculates axial component forces of three hydraulic cylinders through numerical computations. The one axial component force thus entered and three axial component forces thus computed numerically are set as the axial component forces of four hydraulic cylinders.

Abstract: A die cushion force control method and a die cushion apparatus generates a die cushion force on a cushion pad based on a die cushion force command value set in advance. A die cushion force command value equal to or larger than a target die cushion force command value is outputted initially in order to suppress an initial die cushion force overshoot generated when the target die cushion force command value configured to be stepwise is used as the die cushion force command value, then a die cushion force command value decreased continuously (gradually) so as to be smaller than the target die cushion force command value is outputted, and subsequently a die cushion force command value increasing gradually so as to be equal to the target die cushion force command value is outputted.
