  • Battery and electronic apparatus
    Patent number: 8409748
    Abstract: A battery and an electronic apparatus are disclosed by which it can be discriminated with a simple configuration whether or not the battery is of a thin type. The battery is configured such that a wall portion for discrimination of a battery characteristic which is swollen in a lengthwise direction and connects to a connector section is formed at a location of one of end faces positioned rather near to an end portion in a widthwise direction of a case of the battery.
    Type: Grant
    Filed: November 4, 2005
    Date of Patent: April 2, 2013
    Assignee: Sony Corporation
    Inventors: Hideki Hagiwara, Michihito Kobayashi, Yoshihiro Konno, Shoichi Shintani, Yoichi Miyajima, Tsugio Sameshima, Tomohiro Tsumura, Kazuhiro Kitagawa, Kiyoshi Miyamori, Toshio Takeshita, Atsushi Takahashi, Naoto Hosoya, Yoshihisa Tsuchida, Seiya Amatatsu, Nobutatsu Takahashi

  • Multi-rate constant voltage battery charger with display
    Patent number: 5172044
    Abstract: A voltage setting value for charging a battery starts from a first constant voltage level less than a full battery voltage and after a period of time the battery voltage reaches that first level and the charging current begins to decrease. The charging current decrease is detected and the voltage value is increased to a next constant voltage level and the process is repeated until the constant voltage level is reached that equals the full battery voltage. Each time the voltage level is changed the corresponding percentage of the battery voltage is displayed to represent the charging amount.
