Title: Outputting method for measured value of digital apparatus for measuring length
Inventor: YAMAMOTO SEIJI
IPC: G01B21/00
Filed: 1982-10-08
Abstract: PURPOSE:To enable the calculation of a stable measured value by setting a time interval of one period of a low-frequency oscillation affecting the measured value or of an integer multiple of said period, by sampling a plurality of measured values, by calculating an average value thereof, and by removing thereby the low-frequenct oscillation. CONSTITUTION:The relative displacement amounts of a scale 3 and s reading head 4 are input to a counter 6 and counted thereby. Oscillation frequencies different according to the environment of measurement are set appropriately by a time setting circuit 7 for setting a time interval of one period of low-frequency oscillation or of an integer multiple thereof. A sampling rate is set by a clock circuit 8. A storage circuit 9 accumulates and stores data input within the time interval set by the time setting circuit 7. An average value calculating circuit 10 divides an input value from the storage circuit 9 by the number of sampling data and delivers an average value obtained from the division. As the result, the oscillations of comparatively low frequencies are removed and a stable measured value can be obtained.

Filed: 1987-07-16
Abstract: PURPOSE:To obtain a buffer oscillator immune to noise mixing or missing of a synchronizing signal by using a window signal of a period measurement means to control the passing of an external synchronizing pulse generated from the external synchronizing signal. CONSTITUTION:A period measuring means 11 counts a clock pulse S2 and consists of a counter whose count is stopped at a prescribed count, an initial value is set on the counter by triggering (loading) of the external synchronizing pulse S3 to measure the period of the external synchronizing pulse S3 by a time TM till the count is stopped by a prescribed count.
