Latest Patents
One of Nakamura's latest patents is for an AT-cut crystal oscillating reed and the method of etching the same. This invention involves an AT-cut crystal oscillating reed formed by etching an AT-cut crystal wafer. The wafer features a rotational parallel cut, which is achieved by rotating a parallel cut by an angular degree relative to the X-axis of the wafer. The etching cross-section of the reed has a surface at an angle of about 90 degrees from the front or back surface. This design ensures uniform characteristics and excellent reliability. Additionally, the patent describes a method of etching the reed from the wafer, utilizing a corrosion-resisting film with gaps. This innovative approach allows for the mass production of crystal oscillating reeds at a relatively low cost.
