Inventor: ODA YOSHIO
IPC: C25B9/19
Filed: 1980-10-03
Abstract: PURPOSE:To prevent the degradation in the performance of exchange membranes and obtain hydrogen efficiently with low voltage by forming a gas and liquid permeable porous layer having no electrode activity on the surface of a cation exchange membrane used for an electrolytic cell for water. CONSTITUTION:A gas and liquid perfmeable porous layer of about 10-99% porosities and about 0.01-200mu thicknesses having non electrode activity is formed on the surface of a cation exchange membrane formed of a fluorine-contg. polymer or the like having sulfonic acid groups or carboxylic groups. As a method for forming the porous layer, a method of mixing fine powder of metal oxides such as, for example, titanium oxide, tantalum pentaoxide, or the like and a binder, a thickner, etc. to prepare a paste, and screen-printing the paste on the surface of an ion exchange membrane by using such paste is used. The resultant cation exchange membrane is disposed between an anode a cathode, and water is electrolyzed, whereby the occurrence of phenomena such as blistering of the exchange membrane is prevented.

Filed: 1982-08-10
Abstract: PURPOSE:To improve the efficiency of line utilization in case of forgotten hook- on, by detecting a busy tone and a howler tone by a connector of cordless telephone to bring the line to an idle line state. CONSTITUTION:A line relay 13 contacts only during calling, a signal from a terminal is inputted to a transmission section 16 and a tone detecting circuit 17 via the relay 13 and a hybrid circuit 14, and the signal inputted to the transmission section 16 becomes a transmission modulating wave and is outputted to a receiving section 32 from an antenna 20. When the busy tone or the howler tone of a telephone exchange is detected at the circuit 17, the detecting signal (a) controls the relay 13 to interrupt the connection to bring the line to an idle line state, and a detecting signal (b) controls the transmission section 16 to interrupt the output to prevent useless power consumption, thereby bringing the line to the idle state, that is, using effectively the assigned transmission and reception frequency.

It follows that the electrodes 11 and 13 are formed, respectively, on both sides of the inside and outside of the solid electrolyte 12 this way, and that the electrode 13 at the outermost layer is exposed to the outside as it is, but the electrode 11 on the inner periphery side is lead out to the outside through the gas supply pipe 14 leading to this. Hereby, if each element such as the solid electrolyte 12, etc., is formed in order to the outer periphery of the element on the inner periphery side, that will do, and unefficient work such as masking, etc., can be obviated, and work efficiency in manufacturing can be improved.
