IPC: G01C19/64

Abstract: @ A gyroscope system includes a coherent light source that supplies counterpropagating waves to a sensing loop through a pair of directional couplers. The polarizations of the waves are controlled so that they traverse identical paths before recombining in one of the couplers to form an interference pattern. Rotation of the sensing loop, a phase modulator and a frequency shifter cause phase changes in the counter propagating waves. A detector monitors the interference pattern of the combined waves and provides a signal to the coherent demodulator that controls the phase modulator. The output of the coherent demodulator is input to a servo loop circuit that drives a voltage controlled oscillator. The output of the voltage controlled oscillator is an oscillatory signal having a frequency equal to the shift in frequency that the counter propagating waves experience in traversing the frequency shifter. The feedback circuitry adjusts the frequency shift to null the phase difference between the counterpropagating waves. The frequency shift is linearly related to the frequency of the signal output from the voltage controlled oscillator. Each cycle of the output of the voltage controlled oscillator corresponds to a fixed angular increment of displacement of the sensing loop. The rotation rate of the sensing loop is a function of the frequency shift and transit time of the waves through the sensing loop. The gyroscope system determines rotation rates and angular displacements over a wide dynamic range by measuring the frequency and zero crossings of the oscillatory output of the voltage controlled oscillator.

Abstract: During the transfer of semiconductor elements, they are conveyed in containers closed on all sides to prevent contamination. The container can only be opened under clean-room conditions. The new container and the new method are intended to prevent any contamination even if the container is not stored or manipulated under clean-room conditions. 
<??>In the container, a directed and at least approximately laminar clean-air current flows round semiconductor elements (2) in the clean- air region. At the same time the static pressure in one clean-air region is higher than in the ambient space polluted with an impermissibly large number of particles. The clean-air current entrains any dirt particles still present so that they are not able to deposit on the semiconductor elements (2). As a consequence of the higher static pressure, a forced outward flow from the clean-air region with the higher static pressure into the ambient space is achieved, as a result of which entry of dirt particles from the ambient space is prevented.
