  • Publication number: 20220147640
    Abstract: A secret sharing storage system includes at least one user terminal, n units (n: an integer of 2 or more) of storage devices, and a main controller that is communicably connected to a random number generator. The main controller acquires a random number generated by the random number generator in a case of receiving original data sent from the user terminal, executes distributed processing on the original data by using the random number to generate n pieces of distributed data, and stores the n pieces of distributed data respectively in the corresponding n units of storage devices.

  • Patent number: 9871485
    Abstract: The stepper motor driver circuit controls driving of a stepper motor. The stepper motor driver circuit generates a driving current having a pseudo-sinusoidal waveform that varies stepwise every one period of a reference clock signal and makes the waveform of the driving current vary in response to a measurement value of an exciting voltage on a coil of the stepper motor at a time when the driving current is zero.

  • Publication number: 20160352281
    Abstract: A motor driving circuit includes a frequency dividing circuit that outputs a divided clock signal obtained by dividing a reference clock signal, a temperature detecting element that detects a temperature in the motor driving circuit, a selecting circuit that receives the clock signals, and output one of the clock signals according to the temperature detected by the temperature detecting element, and a motor driving output unit that outputs a motor driving signal based on the selected clock signal. When the detected temperature is a predetermined temperature or more, the selecting circuit outputs the divided clock signal instead of the reference clock signal.
