  • Publication number: 20150068880
    Abstract: An operating device includes a push operation mechanism including an operating portion to be push-operated, a tactile presenting means that drives the operating portion, a detecting portion for detecting movement of the operating portion, and a drive control unit that drives the driving portion by a drive control signal and a main vibration pulse signal output after outputting the drive control signal, the drive control signal being generated based on a start pulse signal and a pre-vibration pulse signal. The drive control unit sets a mask time to invalidate a detection signal of the detecting portion in a certain period when the drive control signal is output and switches from the output of the drive control signal to the output of the main vibration pulse signal based on a detection signal of the detecting portion after an elapse of the mask time.

  • Patent number: 7986256
    Abstract: An external input operation clock signal is required for operating a conventional A/D converter, and the performance of the A/D converter is undesirably determined by the characteristics of the external input operation clock. A clock generator circuit for automatically generating an operation clock is provided inside an A/D converter to make the A/D converter require no external input operation clock. Further, a circuit for detecting the operation times of the constituents of the A/D converter is provided to generate a clock with which the A/D converter is optimally operated, thereby realizing high-speed operation and low power consumption.

  • Patent number: 7834794
    Abstract: The conventional A/D converter has a drawback that the conversion precision is degraded when the operation periods of the constituents of the A/D converter are shortened due to the duty ratio of an external input clock because the operation periods of the constituents of the A/D converter depend on the pulse width of the external input clock. However, a highly-precise A/D conversion operation independent of the duty ratio of the external input clock can be realized by providing a circuit for detecting the operation periods of the constituents of the A/D converter, and adjusting the duty ratio of the operation clock according to the detected operation periods of the constituents of the A/D converter.

  • Publication number: 20100270648
    Abstract: A semiconductor integrated circuit has a plurality of capacitor cells, and each capacitor cell has an upper electrode and a lower electrode. These electrodes are respectively connected to an upper electrode wiring and a lower electrode. When, for example, the upper electrode is connected to the upper electrode wiring and the electrode wiring is located at a side of the lower electrode of another capacitor cell or a side of the lower electrode wiring connecting these electrodes, a shield wiring is provided between the upper electrode wiring and the adjacently-located lower electrode of the other capacitor cell or between the upper electrode wiring and the adjacently-located lower electrode wiring. Thus, with this shield wiring, the capacitance coupling between each wiring of the capacitor cells and each upper electrode or each lower electrode of the capacitor cells are effectively suppressed.
