Title: Electrolyte-concentration detector for lead storage battery
Inventor: KAMATA YUKINARI
IPC: G01R31/36
Filed: 1978-10-16
Abstract: PURPOSE: To detect the electrolyte-concentration with high precision without being influenced by the variations and fluctuations of the electrolyte surface, by receiving the light reflected from the bottom surface of a prism contacting the electrolyte by an array of light receiving elements, and detecting the change of the index of refraction of the electrolyte due to the change of the electrolyte-concentration.  
     CONSTITUTION: The detector is formed of a point light-source 1, a slit 2 for limiting the angle of the light emitted from this light-source, a prism 3 having a bottom surface in contact with the electrolyte 4, and an array of light-receiving elements 5. If the angle of incidence of the light incident upon the bottom surface of the prism 3 at a point β' is just equal to the critical angle between the prism and the sulfuric acid at that time, the light quantity received by the array of light-receiving elements 5 suddenly increases from a point β where the critical angle condition is established. Thus, when the concentration of the sulfuric acid, and hence the index of refraction thereof and said critical angle are changed, the position of the light- receiving element from which the received light quantity suddenly increases is also changed, so that this can be utilized to detect the electrolyte-concentration with high precision.

Abstract: PURPOSE:To correct the detection signal of a metric unit by regarding the output signals from a plurality of metric units, deviated from the previous combinational operation, as dummy signals and detecting vibration of the floor on which the metric units are disposed based on the components of vibration and then calculating the vertical displacement. CONSTITUTION:Metric units 11-1n weigh objects at weight detecting sections 271-27n thereof to produce signals W1-Wn which are fed to a multiplexer 2 through amplifiers 31-3n. A selected output is then fed through an A/D converter 4 to a CPU 5. A combinational operating means in the CPU 5 then performs combinational operation on the signals W1-Wn to select a combination of total weight values closest to a target value thus driving the gate driving sections 281-28n correspondingly. Metric signals W1-Wn from the metric units 1i-1n not employed in the combinational operation are regarded as dummy signals and the oscillation mode of the floor F is detected based on the components of vibration thus calculating the vertical displacement. The calculated displacement is then subtracted from the signals Wi-Wn thus removing the influence of the vibration of floor.
