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: A vibration transmission damping apparatus (1) is attached to a structural object (13) and supports the structural object (13). The vibration transmission damping apparatus (1) includes a cylinder (2) and a piston (3) arranged inside the cylinder (2). A space enclosed by the piston (3) and the cylinder (2) forms a fluid chamber (4) which is filled with air. The piston (3) supports the structural object (13) by pressure generated by the air. A fluid passage (7) which communicates the fluid chamber (4) with the outside is connected to the fluid chamber (4). Further, the fluid passage (7) is provided with an on-off valve (8V). The on-off valve (8V) is opened/closed at frequency of vibration whose transmission to the structural object (13) is not desirable so as to discharge the air in the fluid chamber (4) to the outside.

Abstract: A vehicle-body supporting apparatus is provided between a vehicle body of a vehicle and a wheel to support the vehicle body. The vehicle-body supporting apparatus includes an air chamber that is filled with a gaseous matter, a vibration input unit that inputs at least one of vibration from the vehicle body and vibration from the wheel to the air chamber by reciprocating relative to the air chamber, a fluid path that the gaseous matter in the air chamber passes through, and a fluid-path opening/closing unit that is attached to the fluid path to open/close the fluid path at predetermined frequency corresponding to a frequency of reciprocation of the vibration input unit relative to the air chamber.

Abstract: This vehicle body supporting system includes a gas passage that interconnects a gas chamber of one vehicle body supporting unit and a gas chamber of another vehicle body supporting unit and a gas passage opening/closing unit disposed on the gas passage. The gas passage opening/closing unit opens and closes the gas passage at a predetermined frequency corresponding to a frequency of reciprocative movement of transmission components of the vehicle body supporting units relative to the gas chambers.

Abstract: Evaluation tires, each having a plurality of structural elements including a target structural element, are prepared. Only the experimental structure of the target structural element is different among all the evaluation tires, while the structures of other structural elements are identical. Radial force variation of each of the evaluation tires is measured. Corrected radial-force variation of each of the evaluation tires is calculated by subtracting a 1st order component of the radial force variation from the radial force variation, and the structure of the target structural element is determined based on the corrected radial-force variations of the evaluation tires. This process is repeated for other structural elements.
