The picture is processed on an oscilloscope 32 as the waveform corresponding to the impression and the level of luminance signals becomes convex downward. The width size of the projecting waveform 32a is calculated as time elapses and outputted to a printer 33. The abrasion loss of the tape sliding surface 1a of the head 1 can be found from the variation of the opened state of the impression 7.

Filed: 1995-12-13
Abstract: PROBLEM TO BE SOLVED: To keep the quality of a platinum-membrane joined body constant by using a complex salt consisting of a platinum ammine complex ion and a hydroxide ion as a platinum ion source. SOLUTION: A platinum ion is adsorbed on a cation-exchange resin membrane by ion exchange. A platinum metal layer is then deposited on the membrane surface by the use of a reducing agent to produce an electrode- membrane joined body for electrrolysis. In this case, a complex salt consisting of a platinum ammine complex ion and a hydroxide ion is used as a platinum source. Tetraammine platinum dihydroxide (Pt(NH3 )4 )(OH)2 or hexaammine platinum tetrahydroxide (Pt(NH3 )6 )(OH)4 is used as the platinum ion source. A perfluorohydrocarbon resin membrane having a sulfonic group or a carboxylic group is used as the cation-exchange resin. As a result, the variations in platinum ion exchange are prevented.
