Title: Measuring apparatus for reaction of metallic hydride
Inventor: NISHIZAKI MICHIYOSHI
IPC: C01B6/00
Filed: 1980-12-17
Abstract: PURPOSE: To accurately measure the degree of hydrogenation reaction in an instantaneously responding way by placing an elastically deformable partition wall in a reaction  measuring chamber formed at the inside of a reactor and detecting a change in the  volume of metallic hydride due to the occlusion of hydrogen.   
     CONSTITUTION: Each cylindrical wall 11 and each wall body 12 made of sintered metallic body or the like permeable to gaseous hydrogen and impermeable to metallic  hydride are unitedly set at the inside of the wall 10 of a reactor to unitedly form a  reaction measuring chamber 13 and a blank chamber 14. The chambers 13, 14 are  parted by partition walls 15 made of elastically deformable stainless steel sheet or the  like impermeable to gaseous hydrogen. The wall 15 of the chamber 13 undergoes elastic  deformation in accordance with changes in the pressure of gaseous hydrogen and in  the volume of metallic hydride 16. The wall 15 of the chamber 14 undergoes elastic  deformation in accordance with a change in the pressure of gaseous hydrogen. By  detecting the deformations with deformation detecting elements 17, a change in the  volume of the metallic hydride 16 in the chamber 13 corrected with the element 17 of  the chamber 14 is detected in an instantaneously responding way. Accordingly, the  degree of hydrogenation reaction of metallic hydride 1 is measured accurately.

Abstract: PURPOSE:To reduce interference noise by stopping a frequency divider generating a frequency divider signal not selected by a frequency divider signal selector. CONSTITUTION:A stop controller 1 provided in the inside of a switched capacitor filter(SCF) driving clock signal generator 8 outputs a stop signal to stop each frequency divider to any of signal lines 3-5 by using a control signal outputted to a signal line 2 from an external device 6 and the frequency divider receiving the stop signal is stopped. A frequency divider signal selector 15 uses a signal of a selection control signal line 10 outputted from the external device 6 so as to select the required frequency divider signal and an SCF drive clock signal 17 is outputted to the signal line. The SCF drive clock signal 17 is inputted to the SCF 18 to form a filter having a required band. Thus, no signal exists in mixture in other frequency divider in the interference noise generated in the frequency divider signal selector 15 and the noise level is minimized.
