    摘要: An automatic insertion bookmark 10 designed to allow a bookmark portion 14 to be automatically inserted into and placed on an opened page 20a of a book 16. The bookmark 10 includes a fixing portion 12, a connecting portion 13, and a bookmark portion 14. The fixing portion 12 is either prefixed to one of the following or fixed thereto when the bookmark 10 is used: a back cover 18 of the book 16; a front cover 20 of the book 16; and, a leaf 19 of the book 16 in the immediate vicinity of either the back cover 18 or the front cover 20. A proximal end of the connecting portion 13 is connected to an upper portion of the fixing portion 12. Further, the bookmark portion 14 is connected to a distal end of the connecting portion 13. When the bookmark 10 is used, the bookmark portion 14 is folded downward at a portion where the bookmark portion 14 and the connecting portion 13 are joined together. As a result, the bookmark portion 14 is directed downward in an opposed relationship to the fixing portion 12.

    摘要: A vehicle includes a PCU controlling electric power supplied to a motor, a first power storage device, a second power storage device, an ECU, a charger, system main relays SMR1 to SMR4, SMRA, SMRB, and charging relays CR1 to CR4. The first power storage device is formed such that a first module and a second module which are separately disposed are connected in series through SMRA and SMRB. The first power storage device is connected to the PCU through SMR1 and SMR2. The second power storage device is connected to the PCU through SMR3 and SMR4. The charger has a capacitor that is connected to the first power storage device through CR1 and CR2 and also connected to the second power storage device through CR3 and CR4. When charging is completed, the ECU turns on CR1, CR2, SMR1, and SMR2, and turns off SMRA, SMRB, CR3, CR4, SMR3, and SMR4.
