This paper describes an automatic step and repeat reduction camera with precision positioning by applying the theory of light interference, using a He-Ne gas laser for light source. The camera consists of a laser interferometer system, a set of precision mechanism, a numerical control device and a laser frequency stabilizer. The displacement of the working table is measured and located by the laser interferomenter system, so the accuracy of the camera in repeat positioning is better than micron. In this paper,...

This paper describes an automatic step and repeat reduction camera with precision positioning by applying the theory of light interference, using a He-Ne gas laser for light source. The camera consists of a laser interferometer system, a set of precision mechanism, a numerical control device and a laser frequency stabilizer. The displacement of the working table is measured and located by the laser interferomenter system, so the accuracy of the camera in repeat positioning is better than micron. In this paper, the properties in the design of the laser interferometer system and the problems concerned with application of laser to precision positioning of the working table in the camera are given with some emphasis. At the sametime, it affords major technical parameters and experimental data. At the end of this paper, the analysis of accuracy and the result of calibration of the cameras show that actual accuracy of the cameras is up to about e0.75 micron. Cameras of this type are now used in industrial practice.

>=The resonance effect of thermoacoustic prime mover is analyzed in this paper. The resonator coupled to the oscillation system with smaller amplitude and higher frequency is a frequency stabilizer. Its operation frequency is decided by the rate of energy input to energy dissipation of the resonator. If the energy input is smaller than the energy dissipation of the resonator, the resonator will not work. If the energy input is bigger than the energy dissipation of the resonator, the resonator works with corresponding...

>=The resonance effect of thermoacoustic prime mover is analyzed in this paper. The resonator coupled to the oscillation system with smaller amplitude and higher frequency is a frequency stabilizer. Its operation frequency is decided by the rate of energy input to energy dissipation of the resonator. If the energy input is smaller than the energy dissipation of the resonator, the resonator will not work. If the energy input is bigger than the energy dissipation of the resonator, the resonator works with corresponding frequency. The higher frequency is, the bigger energy dissipation of the resonator is, because energy dissipation of resonator increases with the square of oscillation frequency of resonator. The mode of operation of a thermoacoustic prime mover changes from higher energy dissipation to lower energy dissipation.

分析热声热机的谐振效应,一个与小振幅高频率振动系统相结合的谐振管是一个频率稳定器,其稳定的频率由输入谐振管的能量和谐振管的损耗之比来决定。当输入谐振管的能量小于谐振管的损耗,则谐振管可能停振。当输入谐振管的能量大于谐振管的损耗,则谐振管以相应的谐振频率振动。由于谐振管的损耗随频率的平方而增加,频率越高,损耗越大。所以谐振管高频起振后将向低损耗的低能态变化。
