Title: Surface treatment of stainless steel sheet used for front sheet of gas range or the like
Inventor: MIDORIKAWA KATSUO
IPC: C23C22/00
Filed: 1993-02-03
Abstract: PURPOSE:To secure the adhesion of a PFA film to a stainless steel sheet by heating the surface of a passivated stainless steel sheet and adhering the PFA film to the roughened surface. CONSTITUTION:A stainless steel sheet to be used for the front sheet of a gas range, etc., is surface-treated as follows. Namely, the stainless steel sheet St is sandblasted to form a relatively rough surface of about 8-24# having a sharply edged recess 1 in the first stage. The sheet St with the surface roughened is dipped in concd. nitric acid to passivate the sheet St surface in the second stage. The sheet St surface is heated to 330-440 deg.C in the third stage. A PFA film is adhered to the roughened surface of the sheet St in the fourth stage. Consequently, the sharp edge of the recess is not deformed when heated.

Filed: 1995-03-13
Abstract: PURPOSE: To optionally set process contents corresponding to key input by an application on the side of an information center by processing a key code inputted at the information providing terminal by the terminal itself or sending it out through the terminal as it is. CONSTITUTION: When there is key input to the information providing terminal 19, whether the key code is to be outputted to a central control unit 9 through the terminal or to be processed by the information providing terminal 19 itself is selected. For example, the key codes of a stop key and a resinging key in KARAOKE mode and even a ten-key, a determination key, etc., in information service mode are sent out to the central control unit 9 through the terminal. Consequently, different processes differing with applications such as a process wherein the ten-key is regarded as the specification of its number as it is and a process wherein the code of the ten-key is processed as a selection number when a specific selection candidate is selected out of plural candidates can be coped with by modifying the program only on the central control unit side 9.
