Abstract: Provided is a high-performance sliding seismic isolation device with a slider that realizes a contact pressure of 60 MPa. The device includes an upper shoe 1 and a lower shoe (2) having sliding surfaces 1a and 2a with curvatures, respectively; and a columnar steel slider (7) disposed between the upper shoe (1) and the lower shoe (2), the slider having an upper surface 4a and a lower surface 4b that are in contact with the upper and lower shoes, respectively, and have curvatures. The upper surface 4a and the lower surface 4b of the slider (7) have double-woven fabric layers (5) and (6), respectively, each double-woven fabric layer containing PTFE fibers and fibers with higher tensile strength than that of the PTFE fibers, and the PTFE fibers being arranged on the sides of the sliding surfaces 1a and 2a of the upper shoe (1) and the lower shoe (2).

Abstract: A plurality of battery modules are provided for each module monitoring unit. When a battery module is normal, a photo-FET of a photocoupler contained in a module monitoring unit 5 associated with the battery module is turned on. When it is abnormal, the photo-FET is turned off. Those photo-FETs, provided in association with the battery modules, are connected in series by two signal lines. A management unit detects whether the circuit including those signal lines is opened or closed, and finds an abnormal battery module on the basis of the detection.

Abstract: Forced discharging circuits each of which is configured by connecting in series a transistor, a reverse blocking Zener diode, and a discharging resistor are connected between positive and negative output terminals of cells, respectively. In each of the Zener diodes, the Zener voltage is set to be substantially equal to the cut-off voltage of discharge of the corresponding cell. The bases of the transistors are connected to a switching control circuit. The transistor of each of the forced discharging circuits is set so as to have a larger on-duty ratio, as the cell to which the forced discharging circuit is connected is remoter from a ground line, so that the average currents flowing through the cells are equal to one another.

Abstract: A steel center axis force member passes through a steel buckling-restriction member. A stick preventing coat is disposed between the surface of the center axis force member and the buckling-restriction member. Thereby, a buckling-restriction bracing member having a narrower body and lighter weight can be provided to facilitate a rapid manufacture with lower cost.
