The three words alone have power to conjure: "Alpine pink fluorite" evokes images of transparent pink or rose-red octahedral crystals resting on clean-looking, coarse-grained white granite, or squatting directly on mirrored faces of gemmy smoky quartz crystals. To recall or imagine such specimens is somehow to call up the exotic, the fugitive and elusive--clearly, in Alpine pink fluorite there is an otherworldliness not to be found in the fluorites, however beautiful, from Weardale or Dalnegorsk or Xianghualing or Cave-in-Rock.
The electronics industry is now enabled with a new technology that allows the integration of small, high Q, low ppm, single or multiple resonators, at a cost below quartz crystal products.
As no small quartz crystal unit was oscillating at this frequency, Kyocera Kinseki divided higher frequencies, such as 16MHz, using IC, to obtain 4MHz.
This technology builds on the fundamental basics of the quartz crystal microbalance (QCM) [1] with several key additional features that are detailed in the Materials and Methods and Results and Discussion sections.
QUARTZ crystal is an excellent balancer and stimulates good health on all levels.
The IMT-202 is a twelve-note even-tempered tuner that uses a quartz crystal, it has a tolerance of +/- 0.5 cents and a calibration mode of 430-439 hz, allowing the pitch to be modified up or down in 1 hz steps.
Accuracy is achieved in the 3f by the use of three discrete quartz crystal oscillators.
