Title: Rf chain circuit for atomic clock
IPC: H01S1/02
Filed: 1992-07-30
Abstract: PURPOSE: To utilize a digital frequency dividing circuit by increasing the frequency of a surface acoustic wave oscillator (SAW) and to obtain superior insulation by suppressing a phase shift which depends upon the temperature. CONSTITUTION: A SAW 60 for a high-frequency oscillator 46 is constituted by using a readily available SAW of 640MHz and a two-frequency-dividing circuit is provided to reduce its frequency to 320MHz. One of its outputs drives a cesium beam tube through a multiplier 68. The 2nd output demultiplexes a standard output frequency of 10MHz through a frequency divider 69. Further, the 3rd output generates a phase lock signal through a low-frequency oscillator 44. Therefore, the necessary multiplication quantity is reduced o 1/32 as large as usual. The reduction of a multiplication coefficient reduces problem points regarding temperature. Further, the SAW outputs are less than the phase noise of a conventional crystal control oscillator which is multiplied to the same frequency, so a superior microwave signal can be supplied to the cesium beam tube.

IPC: B02C17/16
Filed: 1990-08-23
Abstract: PURPOSE:To increase crushing efficiency by providing an agitated chamber in a cylindrical vessel and erecting a pillar having a square cross section rotatably at the center of the chamber. CONSTITUTION:The balls 7 made of nickel - chromium steel with the surface hardness enhanced by hardening are packed in an agitated chamber 1c as a crushing medium so that the total volume of the balls 7 is adjusted to about 80% of the volume of the chamber, and a material 9 to be crushed is charged from a passage hole 8a while rotating a square pillar 3. Since the shape of the cross section of the space partitioned by the side surface of the pillar 3 and an attachment 4 is varied, the balls 7 in the space are irregularly moved and agitated. Consequently, the material 9 is crushed by the impact and frictional force of the ball 7 and moved downward between the balls 7 by gravity, and the crushed material 9 is continuously discharged outside a cylindrical vessel 1 from the slit 6a of a perforated plate 6 through an outlet 1b. The crushing efficiency is drastically increased in this way.
