  • Patent number: 6001171
    Abstract: ST-cut and AT-cut quartz seed bodies (18,40) for quartz crystal synthesis and method (100) for making the same are disclosed. An extended quartz seed body (18) having an angle of about 42.75.degree. rotated about a X axis (20) from a +Z axis (22) to a -Y axis (24) and defining a ST-cut is provided and a quartz crystal bar (32) is grown thereupon. Analogously, an extended quartz seed body (40) having an angle of about 35.25.degree. rotated about a X axis (20) from a +Z axis (22) to a -Y axis (24) and defining an AT-cut is provided and a quartz crystal bar (48) is grown thereupon. In each case, the subsequent quartz crystal bar (32,48) may be wafered parallel to the seed body (18,40) thereby; reducing waste (68), recovering the seed body (18,40) for reuse, producing wafers (70) without intervening seed portions, and increasing factory capacity.
    Type: Grant

  • Patent number: 4631197
    Abstract: A method and apparatus is disclosed to allow the frequency adjustment of a crystal resonator sealed in a housing. The housing includes a transparent area which has plating material deposited thereon. The plating material is vaporized by a laser beam which sprays onto the crystal resonator thereby adjusting the operating frequency. The laser beam is scanned over the transparent area until an effective amount of plating material has been vaporized to adjust the frequency of the crystal resonator.
