Abstract: A first switching unit switches a first power grid from an isolated operation to a grid-connected operation. In switching the first power grid from the isolated operation to the grid-connected operation, the first switching unit determines a master and a slave among a plurality of power adjustment resources and allows the first power grid to be connected to the second power grid after master-slave control by means of the master and the slave such that electric power of the first power grid is in synchronization with electric power of the second power grid. The first switching unit preferentially selects as the master, a power adjustment resource close to a point of connection between the first power grid and the second power grid from among the plurality of power adjustment resources.

Abstract: A power management system includes a plurality of power adjustment resources electrically connected to a microgrid. The plurality of power adjustment resources include a plurality of EVSEs, each of EVSEs including a parking space. When any one of a plurality of power feeding vehicles is parked in the parking space, an EVSE enables power feeding from a vehicle parked in the parking space to the microgrid. A CEMS server manages the parking space. When a balance of power supply and demand in the microgrid is in an overdemand state, the CEMS server allocates the parking space to a power feeding vehicle that responds to a request for power feeding to the microgrid, of the plurality of power feeding vehicles.

Abstract: A methotrexate-containing transdermal preparation effective for rheumatoid arthritis comprises an organic amine. The organic amine may preferably be an alkonolamine such as monoethanolamine, diethanolamine, triethanolamine or diisopropanolamine, or an alkylamine such as ehtylamine, diethylamine or triethylamine. The transdermal preparation is, for example, a plaster, a cataplasm, an ointment, a cream or a lotion.

Abstract: An improved conveyor system for a so-called drive-in bank through which cash, deposit slip or the like are safely transferred from the customer station to the teller station and vise versa is disclosed. To assure that each of customers who reach the bank is visually recognized from the teller room a plurality of vertical hollow columns at the customer station are arranged one after another in a spaced relation in the direction of reaching of customers' cars and a plurality of vertical hollow columns at the teller station are centralized in a small area adjacent to the teller room. A plurality of horizontally extending hollow beams are fixedly mounted on the top end parts of the vertical hollow columns at both the customer and teller stations in such a manner that the former are turned by a predetermined angle relative to the latter as seen from the above.
