描    述     This paper describes the essential details of a portable shielded temperature-controlled piezo oscillator constant in frequency to better than one part in 100,000. The quartz plate is mounted in a special plate holder so that the air-gap changes very little as the quartz plate shifts in the holder. The plate holder is mounted in a thermal-attenuating chamber consisting of a copper cylinder and layers of asbestos, contained in a wooden box. The copper cylinder is mounted on heavy bronze coil spri...More
