Abstract: PURPOSE:To facilitate the adjustment of the deflection amount of an armature by a method wherein a yoke adjusting mechanism for movably positioning an attraction yoke is provided, and the deflection amount of the armature attracted onto the attraction surface is made variable by movably positioning said attraction yoke. CONSTITUTION:In the adjustment of a printing force, firstly a printing head is assembled, and a printing pressure adjusting screw 12 is set so as to press an attraction yoke 4 by a certain extent.

Filed: 1997-09-26
Abstract: PROBLEM TO BE SOLVED: To prevent turbulence from being generated in the direction of longer side even in a low flow rate region of a flat flow route with large rectangular ratio (W/H) and improve the flow rate measuring precision. SOLUTION: A rectangular flow route 11, in which a fluid flows, is formed and a pair of ultrasonic transmitting and receiving apparatuses 12, 13 are so installed face to face on the upstream side and the downstream side as to make ultrasonic waves transversely cross in the direction in the longer side and partitioning plates 15 (15a-15c) are installed in parallel to the flow direction in the shorter side direction of the rectangular flow route.  With this structure, since turbulence of the fluid in the longer side direction is suppressed and since the ultrasonic waves transmitted and received by ultrasonic wave-transmissive windows 6, 7 of the partitioning plates can not reach the counterpart transmitting and receiving apparatuses unless the ultrasonic waves are transmitted through the ultrasonic wave-transmissive windows, disorder of the received waveforms is prevented and flow rate measurement is carried out at high precision.
