91Pentagrid converter — For other types of frequency converters please, see Frequency converter. The pentagrid converter is a radio receiving valve (vacuum tube) with five grids used as the frequency mixer stage of a superheterodyne radio receiver. Grids of a 12SA7GT… …
92Synchrocyclotron — A synchrocyclotron is a cyclotron in which the frequency of the driving RF electric field is varied to compensate for the mass gain of the accelerated particles as their velocity begins to approach the speed of light. This is in contrast to the… …

94Continuously variable transmission — Transmission types Manual Sequential manual Non synchronous Preselector Automatic Manumatic Semi automatic Electrohydraulic Dual …
95Quadrupole ion trap — Scheme of a Quadrupole ion trap of classical setup with a particle of positive charge (dark red), surrounded by a cloud of similarly charged particles (light red). The electric field E (blue) is generated by a quadrupole of endcaps (a, positive)… …
96Rotational-vibrational coupling — occurs when the rotation frequency of an object is close to or identical to a natural internal vibration frequency. The animation on the right shows a simple example. The motion depicted in the animation is for the idealized situation that the… …
97Optical heterodyne detection — is an important special case of heterodyne detection. In heterodyne detection, a signal of interest at some frequency is non linearly mixed with a reference local oscillator (LO) that is set at a close by frequency. The desired outcome is the… …
