  • Patent number: 9242570
    Abstract: A charging system for a hybrid vehicle which prevents a super capacitor from being reverse charged. In the illustrative charging system a DC-DC converter is connected to the inverter and configured to receive the DC electricity from the inverter and drop voltage. A battery is configured to receive the DC electricity from the DC-DC converter and to be charged by the DC electricity. Finally, a means for preventing reverse charging is mounted on a path between the super capacitor and the battery and is configured to prevent energy from flowing from the battery to the super capacitor.

  • Patent number: 6568110
    Abstract: The present invention relates to a nonrotating billboard of a rotation body which is attached on a surface of a rotation center of a vertical rotation member such as vehicle wheel, fan, etc. for showing a nonrotating state of a pattern, emblem or advertisement irrespective of a rotation of a rotation body. The nonrotating billboard includes a housing rotated together with the rotation member, a billboard member having a surface on which a billboard is formed installed in the housing and rotatable relative thereto while maintaining an upright state through use of a weight member. The nonrotating billboard further includes a friction prevention unit for maintaining a free state of the billboard member such that the billboard is restricted from contacting the housing.
