Abstract: A management system includes a plurality of resources configured to be electrically connected to an external power supply, and a management device configured to manage the resources. The management device includes a planning unit and a management unit. The planning unit is configured to determine a power balancing plan of each of the resources by using first information on a use schedule of each of the resources and second information indicating a magnitude of an environmental load in a process of generating electric power to be supplied by the external power supply. The management unit is configured to manage the resources to cause each of the resources to operate according to the power balancing plan or a modified power balancing plan in power balancing of the external power supply.

Abstract: Disclosed is a display device provided with a circuit board applicable to various models, wherein the operations of a system microcomputer on the circuit board can be switched without using a physical connector. The display device is provided with: a main board applicable to various models; and a TV microcomputer, which is provided on the main board and stores the set value data of each of the models. The main board is provided with: an external memory I/F which has external memory said external memory storing the model identifying information of the display device stored. The TV microcomputer specifies the set value data of the display device on the basis of the model identifying information of the display device, said model identifying information having been read out from the external memory, and the TV microcomputer switches the operation on the basis of the specified set value data.

Abstract: A lead acid storage battery has a cell composed of a positive plate comprising a positive active material layer and a positive current collector plate, a negative plate comprising a negative active material layer and a negative current collector plate, a separator and a frame-shaped gasket. In the cell, the positive plate and the negative plate are laminated with the gasket put between them. The gasket is in contact with peripheral edges of the positive current collector plate and the negative current collector plate. The positive active material layer and the negative active material layer are located in a cell space surrounded by both of the plates and the gasket with the separator put between them.

Abstract: A battery of this invention is equipped with a positive electrode having a following structure. A resin sheet is bonded to one side or both sides of a metal sheet, a large number of through holes are made at least on the resin sheet, and an active material is filled in the through holes.
