  • Patent number: 11586175
    Abstract: A tool is equipped with a torque sensor, suited for a tightening task of a fastening component of a device such as a fluid control system that requires a large number of fastening components for assembly and has a narrow space for access to the fastening components, and capable of automatically detecting a tightening torque. The tool includes a torque sensor capable of detecting a tightening torque for tightening a fastening component acting on a bit. The torque sensor initiates measurement of the tightening torque when the tightening torque detected exceeds a set threshold value, completes measurement when the tightening torque detected falls below the set threshold value and a set time elapses, and outputs torque-related data formed on the basis of measurement data from measurement initiation to measurement completion and including a measurement time. The torque-related data includes a peak value of the measurement data.

  • Publication number: 20210278925
    Abstract: A technique is provided that is capable of obtaining image data for personal identification clearly in a short time at an arbitrary position in an area region at least about several times greater than a fingertip. In addition, a technique is provided that allows smooth progress of a series of process flow in a reservation site and an electronic commerce site for excellent user experience. An information processing system is provided that includes: an input section having a surface and configured to allow a user to contact or approximate a position specifier to the surface for information input; and a processing section configured to perform processing based on the information input to the input section, wherein the input section includes a position detection mechanism configured to detect a position of the position specifier on the surface and a reading mechanism configured to read biometric information of the user.

  • Patent number: 8278910
    Abstract: A PLL for controlling a motor includes first and second feedback loops. The first feedback loop includes an oscillator for generating a signal having a frequency corresponding to an input voltage, a first phase comparator for outputting a first phase difference signal corresponding to a phase difference between the signal from the oscillator and an input signal, and a first smoothing filter for smoothing the first phase difference signal to output the smoothed signal as the input voltage. The second feedback loop includes a second phase comparator for outputting a second phase difference signal corresponding to a phase difference between a signal having a frequency corresponding to a rotational speed of the motor and the input signal, an adder for adding the first and second phase difference signals, and a second smoothing filter for smoothing an output of the adder to output the smoothed signal to the motor.
