  • Rotary electronic component
    Patent number: 10707035
    Abstract: A rotary electronic component includes a base member, a shaft attached to the base member so as to be rotatable around an axis, and a regulating member that regulates a rotation angle of the shaft. The shaft includes a flange section including a projecting sections and recessed sections alternately disposed in a circumferential direction. The regulating member includes a contact member in contact with the projecting sections and the recessed sections of the flange section of the shaft, and a biasing member that biases the contact member radially inwardly toward the shaft.
    Type: Grant
    Filed: September 27, 2018
    Date of Patent: July 7, 2020
    Assignee: MURATA MANUFACTURING CO., LTD.

  • Piezoelectric power generating device having a stress applying member
    Patent number: 9350273
    Abstract: A piezoelectric power generating device that includes a piezoelectric element having a first surface and a second surface opposite the first surface, a stopper, and a lever. The stopper has a first contact surface that is in contact with the first surface. The lever includes a contact portion, which includes a second contact surface that is in contact with the second surface, and a displacement portion. The lever is arranged in such a manner as to be rotatable relative to the stopper around a rotation axis such that the second contact surface presses the second surface when the displacement portion rotates relative to the stopper around the rotation axis.
