Title: Ion concentration analysis
Inventor: MATSUOKA YOSHIO
IPC: G01N27/26
Filed: 1978-03-31
Abstract: PURPOSE: To make it unnecessary to prepare much reference liquid, which is adjusted to an accurate concentration, in an ion concentration analyzer using an ion sensitive electrode by using every time the liquid of suitable ion concentration, which has been measured with a reference liquid, as a calibration liquid upon the measurement of a sample.  
     CONSTITUTION: The electromotive forces of two kinds of reference liquid having different concentrations aL and aH (both of which are known) and a calibration liquid having a concentration aS (of any value) are measured to obtain their respective values EL, EH and ES. Equations I and II (wherein: ΔEL=ES-EL; ΔEH=EH-ES; and S stands for concentration gradient of an ion electrode) are usd to calculate S and aS. Then, this calibration liquid is used to alternately and consecutively measure a sample liquid having a concentration a x  (which is unknown) and the aforementioned calibration liquid. The resultant values E x  and ES are used to calculate the concentration aX of the sample liquid in accordance with Equation III (wherein EX=EX-ES). In other words, since the liquid of any concentration, which has been measured only once, can be used many times for the calibration of the sample liquid, the calibration of the measured values can be remarkably facilitated.

Title: Measuring device of moving body stop position and control device of crane using the same
Inventor: NAGATA AKIRA
IPC: G01B21/00
Filed: 1999-02-17
Abstract: PROBLEM TO BE SOLVED: To obtain a position and an inclination of a moving body brought alongside a station relative to the station in high precision, without contact and surely perform loading and unloading of a cargo loaded onto the moving body by correcting the control data of an automatic crane. SOLUTION: Distances WF, WR to the front and rear reflectors 6F, 6R installed in parallel with the side of a moving body are measured by a front and rear range meters 5F, 5R installed on the station side. A distance W between the station 4 and the moving body is calculated from W=(WF+WR)/2, and inclination θ relative to the station 4 is calculated from θ=tan-1[(WR-WF)/L] (where L is the interval between a front and a rear range meters). In addition, a distance WM to a reflector 6M attached at the middle position on the side of the moving body tilting at an angle ϕ is measured by a range meter 5M at the middle position installed on the station side. The deviation X of the stopping position in the longitudinal direction of the moving body is obtained from X=[WM-(WF+WR/2]tan(θ+ϕ), using WF, WR, and θ.  The control information of the crane is corrected using these W, θ, and X.

Filed: 1983-03-11
Abstract: PURPOSE:To manufacture of a thin-film magnetic head which has an inorganic protection film without cavities nor cracks by charging organic resin in the overhang part of a conductor film formed by electroforming and then forming the protection film.
