- The tips for U / S soldering irons are also coupled to a heating element while the piezoelectric crystal is thermally isolated, not to degrade the piezoelectric element.
- The Sauerbrey equation was first derived by G . Sauerbrey in 1959 and correlates changes in the oscillation frequency of a piezoelectric crystal with mass deposited on it.
- A "'crystal earpiece "', is a type of piezoelectric earphone, producing sound by using a piezoelectric crystal, a material that changes its shape when electricity is applied to it.
- "' John Ernest ( J . E . ) Benson "'was an Australian engineer and researcher who contributed to studies on piezoelectric crystals, television and sound systems, particularly loudspeakers.
- Since weighted strings have obvious shortcomings in real-life devices _ like airbag triggers _ sophisticated accelerometers measure the deflection of materials like piezoelectric crystals, which produce electricity when they are bent.
- This work, for the Anti-Submarine Division of the British Naval Staff, was undertaken in utmost secrecy, and used quartz piezoelectric crystals to produce the world's first practical underwater active sound detection apparatus.
- In these devices, piezoelectric crystals are used to generate high frequency ( 20 60 kHz ) acoustic waves in molten solder layers or batch, to mechanically disrupt oxides that form on the molten solder surfaces.
- Unlike most ink jet printers which fire drops only when needed, the IRIS printer's four 1-micrometer glass jets operate continuously under high pressure, vibrated by a piezoelectric crystal to produce drops at a 1 MHz rate.
- The force mode used in the colloidal probe technique is illustrated in the figure on the left . The scanner is fabricated from piezoelectric crystals, which enable its positioning with a precision better than 0.1 nm.
- A piezoelectric crystal creates an acoustic wave as it vibrates within the gunbody and causes the stream of liquid to break into droplets at regular intervals : 64, 000 to 165, 000 droplets per second may be achieved.
- Cady held more than 50 patents, and was the inventor of the crystal-controlled oscillator, the highly selective narrow-band crystal filter, one of the principal theorists of the ferroelectricity in crystals, and a historian of the science of piezoelectric crystals.
- It was the work of the aforementioned Espenschied and Herman Affel of Bell Labs who patented their piezoelectric crystal " lattice " filters to provide sharp bandpass cutoff that made all single-sideband carrier work developed at Bell Labs possible.
- The acceleration causes the three disks in the safety mechanism to rotate 90?in succession, ungrounding the circuit; the circuit from the nose to the base of the detonator is then completed when the piezoelectric crystal is crushed on impact.
- Michelson interferometers have the largest field of view for a specified wavelength, and are relatively simple in operation, since tuning is via mechanical rotation of waveplates rather than via high voltage control of piezoelectric crystals or lithium niobate optical modulators as used in a Fabry P�rot system.
- The company developed the Micro Piezo inkjet technology, which used a piezoelectric crystal in each nozzle and did not heat the ink at the print head while spraying the ink onto the page, and released Epson MJ-500 inkjet printer ( Epson Stylus 800 cartridge ) in March 1993.
- An improvement over the 8080 is that the 8085 can itself drive a piezoelectric crystal directly connected to it, and a built-in clock generator generates the internal high amplitude two-phase clock signals at half the crystal frequency ( a 6.14 MHz crystal would yield a 3.07 MHz clock, for instance ).
- Although that is no problem for the makers of airbag systems _ who are by far the biggest purchasers _ and far cheaper than a piezoelectric crystal device, Lemaire said that the cost is still about twice what home appliance makers are willing to pay to create washing machines that can sense when their loads are off balance and use the information to automatically adjust their spin cycles.
