Latest Patents

Fumio Kimura holds a patent for a length-extentional quartz resonator. This resonator features a pair of linearly arranged longitudinal oscillating portions that are designed to undergo dominant length-extentional oscillation. The oscillating frequency of this resonator falls within the range of 1.04 MHz to 1.06 MHz. The design includes a rectangular frame member that supports and surrounds the oscillating portions, with an overall length of 4000 μm ± 200 μm. The frame member is equipped with longitudinal frame portions connected to the oscillating portions through transverse support portions, which are engineered to undergo flexural oscillation. The width of these portions is set between 110 μm and 260 μm, effectively suppressing the coupling between the dominant length-extentional oscillation and the flexural oscillation.
