Abstract: PURPOSE:To improve the jointing state of both an ion-exchange membrane and a catalytic electrode layer and to obtain an electrochemical apparatus wherein an internal resistance has been diminished by performing a wet treatment, a fixation and a dry treatment for the ion-exchange membrane. CONSTITUTION:After an ion-exchange membrane 1 has been swelled to a hydrous state by such a method that the membrane 1 is immersed in boiling water, the circumference of the membrane is fixed by a frame or the like made of a resin, thereafter the membrane is dried under vacuum. A catalytic electrode layer incorporating an electrically-conductive catalyst powder such as platinium and a fluorine-contg. high molecular binder such as polytetrafluoroethylene is press- fixed and jointed onto both surfaces of said membrane 1 or the reverse surface to a surface on which a catalytic electrode has been jointed by an electroless plating and thereby a cathode 2 and anode 3 are formed. By said process, an electrochemical apparatus for water electrolysis or the like wherein the jointing strength of both the ion-exchange membrane and the catalytic electrode layer is large and the electric resistance of the jointing interface is small is obtained.

Abstract: PURPOSE:To keep off any useless over speed in an internal combustion engine in a no-load state. CONSTITUTION:When a no-load state is detected by a neutral switch 7 or clutch switch 8, a first timer 12 starts, measuring a first specified time. After measurement, a second timer 16 is energized by a first comparing means 14 while engine speed Ne is judged that it is more than first engine speed Necut stored in an Necut storage means 15.
