Title: Method for roughening stainless steel sheet surface
Inventor: SHIMIZU TAKESHI
IPC: C25F3/06
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To obtain a steel sheet which exhibits a high adhesion property to various kinds of coating materials relating to a wide range of stainless steed kinds by subjecting the stainless steel sheet surface to alternating electrolysis of alternately executing an anode electrolysis at a specific value or above and a cathode electrolysis at potential in a specific range in an aq. ferric chloride soln. SOLUTION: The stainless steel surface is subjected to the alternating electrolysis of alternately executing the anode electrolysis at the potential of >=+0.5VSCE and the cathode electrolysis at the potential of -0.3 to -1.5VSCE in an aq. ferric chloride soln. VSCE denotes the potential (V) to the potential of a satd. calomel reference electrode. As a result, the formation of the ruggedness having the excellent adhesion property to various kinds of the coating materials, such as coating films of org. and inorg. systems and cladding materials on the surface of the steel sheet is made possible. Unless the anode electrolysis is above +0.5VSCE, the rapid formation of good pits is not always possible. The reaction to generate H2 at a sufficiently high rate occurs in the cathode electrolysis at <=-0.3SCE.  Trouble, such as infeasibility of formation of only the shallow pits occurs at the potential baser than -1.5VSCE.

Abstract: PROBLEM TO BE SOLVED: To detect whether or not there is a problem in the wiring which connects a light-receiving element with an IV conversion circuit, by giving an input current to an IV conversion circuit without applying light to the light- receiving element. SOLUTION: When a photodiode 1 receives light, a current flows through a passage K1 . On the other hand, when a switching element 31 within a test circuit is turned on from the outside, the current flows through a course K2 , and the current is drawn out severally from an IV conversion circuit 2. It is so that the current goes by way of a wiring H, by which the photodiode 1 and the IV conversion circuit 2 are connected and the output layer (cathode N) of the photodiode 1 without fail, even in the case that an input current is given to the IV conversion circuit 2 by a test circuit 3. Accordingly, it can detect whether or not there is a problem in the wiring connecting the light- receiving element with the IV conversion element, by giving an input current to the IV conversion circuit without applying light to the light-receiving element.
