Title: Production of edge for speaker diaphragm
Inventor: TSUCHIYA KAZUO
IPC: H04R7/20
Filed: 1980-05-30
Abstract: PURPOSE:To enhance the yield to a raw material, by forming an edge through giving a heating press processes with use of a mold to an edge component piece produced consistently from a columnar raw material. CONSTITUTION:A base material 4 constituting a cylindrical edge is punched and formed from a columnar raw material 3 obtained by giving a mixing and stirring plus a foaming to the edge materials. The material 4 is cut with a prescribed thickness in the direction orthogonal to the direction of axis length to form a ring-shaped edge component piece 4a. The piece 4a is put into a lower die 2 and then receives a heating and pressing process with use of a force plug 1 and the die 2. Thus an edge is obtained. Furthermore, small-sized edge base materials 4' is punched successively out of the residual part 3b that the material 4 has been punched, thereby the residual part is used effectively.

Title: Coagulation of rubber latex
Inventor: TANAKA TATEAKI
IPC: C08C1/16
Filed: 1980-05-30
Abstract: PURPOSE: To coagulate a latex without forming rubber aggelomerate, by coagulating and growing latex particles by adjusting the pH at 7 or below by adding an aqueous lactic acid solution of a specified acid concentration to a conjugated diene type rubber latex at a specified temperature and, then, adding a bacis substance to the latex.  
     CONSTITUTION: In coagulating and growing the particles of a conjugated diene type rubber latex (e.g., poly-1,3-butadiene) by lowering the pH of the latex by addition of an aqueous lactic acid solution, the latex is coagulated by adding the aqueous lactic acid solution to the latex while keeping the temperature at 30°C or above and maintaining the acid concentration of the aqueous lactic acid solution at 1.5W15% and, then, adding a basic substance, e.g., NaOH. It is possible to obtain an industrially useful rubber latex without significantly forming rubber agglomerate and markedly lowering the rubbery polymer concentration.
