Title: Xy stage device
Inventor: YAMAZAKI KAZUNORI
IPC: G12B5/00
Filed: 1993-05-26
Abstract: PURPOSE:To absorb the running precision error of a driving stage and prevent it from being transmitted to a driven stage by connecting the driving stage to the driven stage by a connecting spring. CONSTITUTION:When a driving stage 14 is driven along an X-axial guide 19 and a Y-axial guide 16, this driving force is transmitted to a driven stage through a connecting leaf spring 31. The driven stage 11 is guided in two freedom directions of XY to a standard guide surface 12 by a magnetic absorbing air slide 32. Since the leaf spring 31 is highly rigid for X-axial direction, Y-axial direction and 9, direction, the driving force of the driving stage 14 is faithfully transmitted to the driven stage 11, but the rigidity in Z-axial direction and thetaX and thetaY directions are small. Thus, the running precision errors (DELTAZ, DELTAthetaX, DELTAthetaY) generated in the driving stage 14 are absorbed by the leaf spring 31, and never transmitted to the driven stage 11.

Title: Ultrasonic wave gas flowmeter
Inventor: KASHIWASE YUTAKA
IPC: G01F1/66
Filed: 1991-04-27
Abstract: PURPOSE:To measure a flow rate which in corrected by the specified temperature by using the ultrasonic wave in the gas flowing through a pipe. CONSTITUTION:A pair of ultrasonic wave probes 2 and 3 are arranged so as to face each other through fluid to be measured on the straight line which is inclined with respect to the central axis of a pipe 1 wherein gas flows. An ultrasonic wave is propagated in the forward direction and in the reverse direction with respect to the flowing direction of the fluid. The flow rate of the gas in the standard state is measured by using the time difference between the propagating times of the ultrasonic wave. Since the difference between the propagating times of the ultrasonic wave in the forward direction and in the reverse direction in the measurement is used, the effect of the common fluctuation in the fixed delay time for both directions can be removed. Since the flow rate which is corrected for temperature is obtained by using the relationship among the sound speed, the absolute temperature and the volume, mounting of a temperature transmitter is not required, and the flow rate which is corrected for the temperature can be accurately measured.
