  • Patent number: 11852482
    Abstract: A controller applies a predetermined voltage to a fixed part detection excitation electrode to vibrate a movable part in a second direction and simultaneously applies a predetermined voltage to a fixed part drive electrode to vibrate the movable part in a first direction. The controller acquires, of the movable part, a first resonance frequency along the first direction and a second resonance frequency along the second direction. The controller controls a drive spring adjustment part to adjust a spring constant of the drive spring, such that the first resonance frequency is maintained constant, and controls a detection spring adjustment part to adjust a spring constant of the detection spring such that the second resonance frequency is maintained constant. The controller detects the angular velocity based on a result of synchronously detecting signal from the fixed part detection electrode with the first resonance frequency.

  • Publication number: 20230061042
    Abstract: In a method for manufacturing a micro vibration body having a three-dimensional curved surface, a mold defining a recess part is prepared, and a plate-shaped reflow material is arranged on the mold so as to cover the recess part. Pressure of a space defined by the recess part covered with the reflow material is reduced, and the reflow material is deformed by heating from an upper surface side opposite to a lower surface facing the recess part and by means of the pressure reduced. When the reflow material is deformed, a part of the mold is heated and / or cooled. As another example, when the reflow material is deformed, a mold having a different heat capacity portion is used to generate a temperature gradient in the mold.
