摘要:
A handle system for a rolling luggage case, including a telescoping post members extensible from a retracted position within a luggage case to an extended position protruding from the luggage case, a cross member extending between adjacent end portions of the telescoping post members, and a handle pivotally mounted to the cross member. A post cap member is attached on an end of the telescoping post member that is distal from the luggage case. The post cap member includes a cylindrical bearing surface to which a handle is pivotally mounted. The cylindrical bearing surface includes a pin reception aperture disposed on a circumference of the cylindrical bearing surface. The cylindrical bearing surface and the pin can be fabricated from a rigid structural material, such as metal.
摘要:
Dislocation and etch channel-free quartz resonator blanks are made from a cultured quartz stone by visualizing the dislocation-free areas of the cultured quartz stone by X-ray topography, cutting seed plates for the next generation of crystal growth from the dislocation-free areas of the cultured quartz stone, growing dislocation free quartz from said seed plates using conventional growth techniques, and cutting dislocation-free quartz resonator blanks from said dislocation-free quartz.
