JPS5834193A - Display plate for clock - Google Patents

Abstract

PURPOSE:To obtain a clock display plate which is excellent in its appearance, by forming an electric nonconductor layer on the surface of the display plate of an electric conductor, and electroplating a time display and a pattern electrically on the part which has formed an electric conductor by removing a part of said nonconductor layer. CONSTITUTION:A body 1 of a dial or a panel cover is formed, for instance, by aluminum, and on the surface, an aluminum oxide layer 2 having thickness of about 15-30mu by an anode oxidation method, etc. is formed, and a coating material, etc. are applied. Subsequently, the aluminum oxide layer is partially removed by cutting, etc. As a result, to the part which has become an electric conductor, plating 3 of Ni, Cr, etc. is executed to suitable thickness by the electroplating method, and a time display and a pattern are formed. In this way, a clock display plate which is excellent in its appearance can be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is based on the use of electrically non-conductive materials (mut, o, g4mo, etc.) in the manufacture of wristwatch dials and parting plates. Electrochemistry such as oxidation method ejIIIl&, true!

Elatin l by chemical or physical methods.
Then, in order to remove the electrical non-conductor, it is cut by a mechanical method, and then etched.The electrically conductive parts are plated by an electrical method to create time displays, patterns, letters, etc. It is characterized by the fact.

The content of the present invention will be explained based on the drawings.

FIG. 1 is a partial cross-section of the present invention, where 1 is the main body of the round dial plate and is made of electrically conductive metals and metal oxides, 2 is the main body 1! ! (2) is an electrically non-conductive layer with a shape, 3 is an electroplated layer on the 9th part of the eratin/glue, a pattern, and a letter, and 4 is the etched surface of the part that has become conductive;
b represents *** of the nonconductor layer and the conductive image.

The details of each processing method will be explained below.

The main body 1 is made of aluminum oxide, with a thickness of 415 to 30 pf) formed on both sides of the knife, and an aluminum oxide layer (as'a) formed in the shape 11IL. The countless pores are colored with dyes, pigments, etc.

However, if you use the Photo Regime F method, Regis Reinki is all II! After applying the master coat* properly, remove only the exposed areas that need to be etched with a solvent such as thinner after hardening.

If a mechanical method is used, the oxidized electric tool layer may be partially removed by cutting or the like.

Next, examples of methods using a vacuum distillation method and a sputtering method will be explained.

Example 2 First, aluminum oxide ('Ax's) was applied to the surface of the main body 10 of the dial and parting plate by vacuum vaporization method or sputtering method.
Electrically non-conducting material such as silicon oxide (gipsy Os) 91,000 μm to IP is applied, and after death it is properly mastered by photoetching, printing, painting, etc., and then if it is oxidized silicone, caustic soda is used. , if it is silicon oxide,
Immerse it in concentrated acid and clean the exposed parts.
The thickness of the nonconductor layer 2 is etched slightly. After that, the material of the main body 1 is 1.
Perform 1 plating using the same method as 11H.

The etching method may be reverse sputtering (dry etching using a vacuum device).

As explained above, sP6 has good corrosion resistance characters **W and mR
It is now possible to create a good dial and parting board for the Punto 2-stroke with the glossy surface of the markings, patterns, and letters.

The material of the main body 1 can be electrically conductive metals or metal compounds, and the inks that have passed through the main body IK master can be removed with a solvent such as thinner.
