  • Voltage application time period measuring circuit and power supply apparatus including the same
    Patent number: 8450994
    Abstract: Provided are a voltage application time period measuring circuit which does not require a battery, and a power supply apparatus including the voltage application time period measuring circuit. Each of a voltage application time period memory (32) and a set time period memory (33) is a nonvolatile memory, and hence it is unnecessary to provide a battery for holding information stored in each of the memories in the outside of the voltage application time period measuring circuit (30) and a power supply apparatus cost is reduced correspondingly.
    Type: Grant
    Filed: November 19, 2010
    Date of Patent: May 28, 2013
    Assignee: Seiko Instruments Inc.
    Inventors: Jun Miyanoiri, Shinichi Idomukai, Tomoyuki Nakaue, Teruyuki Iwashima, Takashi Kohata
