Title: Method and device for detecting 3-point designated circular arc
Inventor: KURIHARA KATSUHIKO
IPC: G06T11/80
Filed: 1990-02-28
Abstract: PURPOSE:To quickly delete a 3-point designating circular arc which is not clearly detected out of the detection subjects and to attain the fast detection processing by deciding whether a rectangle including a circular arc crosses a detecting range or not. CONSTITUTION:A rectangle including a circular arc is calculated from the coordinate data on the start points X1 and Y1, the intermediate points X2 and Y2, and the end points X3 and Y3 which display a 3-point designating circular arc on a display device without calculating the center point of the circular arc. Then it is decided whether the rectangle crosses a detecting range or not. If not, no 3-point designating circular arc is detected, if so, the center point and the radius of the 3-point designating circular arc are calculated. Then the cross between the circular arc and the detecting range is decided. Thus it is possible to quickly delete the 3-point designating circular arc that is not clearly picked out of the picking subjects and to increase the detection processing.

Title: Electrolysis method for alkali chloride using cation exchange membrane
Inventor: YOSHIDA MITSUO
IPC: C25B9/23
Filed: 1980-04-15
Abstract: PURPOSE: To make current density in an exchange membrane uniform, lower electrolytic voltage and make possible stable operation by electolyzing alkali chloride in an electrolytic cell using the cation exchange membrane and porous flat plate anodes.  
     CONSTITUTION: In electrolyzing an aqueous alkali chloride soln. in an electrolytic cell divided into an anode chamber and a cathode chamber by a cation exchange membrane, a porous flat plate anode is used as an anode. In this case, gaseous Cl 2  is the easier to vent the nearer the peripheral parts of the pores of the porous parts and the ions of alkali metal are easier to be replenished at the interface between the anodes and the exchange membrane, hence current is easy to flow. Therefore, the voltage drop of the exchange membrane is smaller as the total of the cut  lengths of the pores provided to the flat plates is larger. Particularly if the total cut  end length is kept at about ≥3m/dm 2 , the voltage drop is smaller than the case  when expanded metal anodes are used.
