  • Vehicle charging system and vehicle charging method with first and second charging operations
    Patent number: 9618954
    Abstract: In response to connection of a vehicle with an external power supply, a plug ECU (PLG-ECU) performs a first charging operation of controlling a charger using a target value which is set to a state of charge lower than a predetermined full state of charge, until the state of charge of a power storage device reaches the target value. After the state of charge reaches the target value, the PLG-ECU stops charging of the power storage device, and restarts charging of the power storage device so that the state of charge reaches the predetermined full state of charge at a scheduled time to end charging which is specified through the use of an input unit.
    Type: Grant
    Filed: October 7, 2011
    Date of Patent: April 11, 2017
    Assignees: TOYOTA JIDOSHA KABUSHIKI KAISHA, FUJI JUKOGYO KABUSHIKI KAISHA

  • Optical glass
    Patent number: 8404604
    Abstract: A P2O5—BaO—ZnO—Nb2O5 type optical glass contains 25-50 wt. % P2O5, 15-35 wt. % BaO, 1-25 wt. ZnO, and 3-10 wt. % Nb2O5. The optical glass has a high refractive index (particularly preferably the refractive index nd of 1.6 or more), low dispersion (an Abbe number ?d of 42 or more), a low deformation point, and improved resistance to devitrification upon molding, and is suitable for precision-mold press molding or other molding processes and also suitable for transfer of a fine structure.
