point contact การใช้

• There is theoretically point contact between the teeth at any instant.
• P-type point contact ( PPC ) germanium detectors are used.
• This regulatory body is the one point contact for all food manufacturers.
• First is a regime where the break junction comprises a quantum point contact.
• The symmetry set will have endpoints corresponding to 4-point contact with the circle.
• The seal is designed to have a point contact between the O-ring and sealing faces.
• Unlike all other ultrasonic techniques, RUS ultrasonic transducers are designed to make dry point contact with the sample.
• In France, during the war, Herbert Matar?had observed amplification between adjacent point contacts on a germanium base.
• The tool also makes point contact with the fastener as opposed to the line contact seen in the straight style tools.
• If this were not the case, the contact stress of a load being transferred through a point contact would be infinite.
• During this period the demodulator was usually a carborundum point contact diode, but sometimes a vacuum tube grid-leak detector.
• The pace of the work picked up significantly when they started to surround point contacts between the semiconductor and the conducting wires with electrolytes.
• The small area of the point contact minimized minority carrier storage and capacitance, making these diodes fast enough to function at radar frequencies.
• The integer number N is determined by the width of the point contact and roughly equals the width divided by half the electron wavelength.
• An external magnetic field applied to the quantum point contact lifts the spin degeneracy and leads to half-integer steps in the conductance.
• To maximize the signal-to-noise ratio, Dr . Evenson needed to apply a DC bias to the point contact device.
• In 2013, John Loughhead was appointed as the UK s Focal Point contact for China in the area of energy and renewables until January 2015.
• These motions must have their walk cycle key frames aligned, so that at a given generic time, both motions make a forward point contact.
• This conical geometry creates a linear contact patch which permits greater loads to be carried than with spherical ( ball ) bearings, which have point contact.
• The crossed configuration is less mechanically sound because there is only a point contact between the gears, whereas in the parallel configuration there is a line contact.
