JPH08127200A - Permanent recording plate - Google Patents

Abstract

PURPOSE: To develop a recording medium and recording method to record a matter which wants handing down to posterity for a long time. CONSTITUTION: Information is recorded by sketching characters, patterns and pictures by melting down the surfaces of various ceramic plates (such as lump and vessel) by making use of laser beam 2. Furthermore, if necessary, a plate is baked by filling its engraved part such as the characters with a coloring agent such as colored glass powder. The ceramic plate on which the information is recorded like this is built in a mounment and kept on forever without fade-out of the character.

Description

Detailed Description of the Invention

[0001]

[Field of Industrial Application] The present invention describes feats, social heritage, literary creations, personal backgrounds, etc. on monuments, honorable monuments, tombs, etc. The present invention relates to a permanent recording method and a recording medium for long-term storage in a urn or the like.

[0002]

[Prior Art] Individual achievements, social heritage records, literature,
Write down creations such as art on paper or wood boards, or metal plates,
It is carved on stones and remains as a monument, a prize or a tombstone.

[0003]

It is almost impossible for the above records to remain forever. For example, as seen in the excavation survey of an old burial mound, valuable recorded materials are corroded and faded,
Or most of them are taken away by digging. There is a stone monument in such a valuable record that is resistant to corrosion and is not taken away, but the problem is that engraving work by special technology is necessary and the recording capacity is small to record it. there were. In addition, it may be engraved on a metal plate with good corrosion resistance, but gold, silver, stainless steel, etc. are not only corrosive but also expensive, they can be melted and recast to other things and destroyed. It may not be said that the optimum material is produced.

[0004]

[Means for Solving the Problems] As a recording material for permanently storing records, it has no value for reuse even if it is melted or crushed, has fire resistance and corrosion resistance, and is mechanically robust.
And it is desirable that you can enter detailed characters, patterns and paintings. The present invention includes alumina, silicon carbide,
A ceramic plate (or lump) made of silicon nitride, zirconia, ferrite, etc., the surface of which is irradiated with a laser beam to evaporate and remove lines and surfaces, so that characters, patterns, paintings, etc. are drawn, and this is a permanent recording medium. It is what

Further, one or a plurality of colored glass powder, colored pigments for ceramics, enamel paint or carbon powder are filled in the concave portion of the engraving of characters, patterns, paintings, etc., which have been melted and removed by the laser beam, and heat fusion is performed. By fixing the colorant, the visibility and the aesthetics are further improved.

As another means, an appropriate method such as X
A letter, a pattern, a painting, etc. are engraved from the surface to the depth of the material using a Y plotter, and then the main recording is performed to obtain a recording medium that can be permanently preserved.

[0007]

[Function] By using a laser beam, very fine characters and patterns can be engraved (heated and evaporated) on ceramics. Therefore, a large amount of information can be recorded, and this ceramic corrodes even when exposed to the atmosphere for many years.
The recorded matter is permanently stored without being damaged, burned, worn out, or destroyed for the purpose of diversion.

[0008]

Embodiments of the present invention will be described with reference to the drawings. First, as a recording plate (or recording medium, the same shall apply hereinafter) for permanent storage, a plate-like or agglomerate of fired ceramics such as alumina, silicon carbide, silicon nitride, zirconia, and ferrite is used as the recording medium 1. The surface is irradiated with a laser beam 2 to be heated and evaporated to draw characters, patterns, and paintings to be recorded. A laser beam can be emitted from a laser processing machine under computer control, and very fine characters and patterns can be drawn.

In this embodiment, the laser beam 2 is a continuous output method of a carbon dioxide gas laser beam having a wavelength of 10.6 micrometer and an output of about 10 watts, and a YAG laser beam having a wavelength of 1.06 micrometer and an average output of 30 watts. Characters were drawn using the pulse output method, and good characters were drawn by both methods. Regarding the output condition, the carbon dioxide gas laser can be favorably used in the range of 5 to 20 W, and the YAG laser can be favorably used in the range of 20 to 50 W, and higher output is also possible and the working depth becomes deep. The output format may be pulse output or continuous output.

On the alumina plate, the laser beam 2
The irradiated part and its surroundings are oxidized to cause black or brown coloring that cannot be easily erased. This colored portion has an effect of clearly drawing a character and is beautiful, but coloring around the character is a drawback that spoils the appearance. In order to remove the coloring around the letters, the alumina plate is set to 70 degrees Celsius.
It is effective to heat at 0 to 850 degrees for a short time,
As a result, the coloring of the character portion does not disappear and remains.

When a character or pattern is drawn on the ceramic recording plate made of silicon carbide, silicon nitride, zirconia, ferrite or the like by heating and evaporating with the laser beam, the drawn part appears in the same color as the color of the substrate. The recording medium may be in this state, but in order to improve the visibility and aesthetics, the imaged portion is filled with a coloring agent, and the necessary portions are further sintered or dried under the temperature conditions required for each.

As the colorant, colored glass powder used in Cloisonne, pigments for ceramics, carbon powder, enamel paint, lacquer and the like are effective.

Next, according to the fourth aspect, as shown in FIG. 3, a ceramic material such as alumina, silicon carbide, silicon nitride, zirconia, and ferrite is colored glass powder on the surface of the plate 1a, and a colored pigment for ceramics. , A colorant 3 such as carbon powder is applied, and the cutter 4 is attached to an engraving machine or an XY plotter (not shown) at a depth reaching the base material from the surface in an unfired state, or a chisel, etc. Carve letters and patterns by hand. The engraved ceramic plate 1a is fired at a temperature suitable for the ceramic.
As a result, letters, patterns, or paintings of a substrate color different from the surface of the recording material will appear clearly.

The ceramic recording plate 1 produced as described above is mounted on the surface of a stone monument, a monumental monument 5 or the like, or by being fitted into a pre-engraved concave portion 5 and pasted with an adhesive or the like. (Fig. 4). As a result, the record will not be erased and will be permanently preserved without being destroyed for the purpose of diversion.

In the above description, a plate-shaped or lump-shaped ceramic is described, but it goes without saying that a container-shaped recording medium can also be used. For example, in FIG.
It is also possible to record on the surface or the inner surface of the box-shaped body 7 as shown in, the surface of an urn or the like, and its use is various.

[0016]

By controlling the laser beam with a computer, fine characters can be drawn, and a large amount of information can be recorded on a ceramic having a small area. Moreover, the recorded information is not erased, corroded or worn, and is not destroyed for the purpose of recycling, and is effective as a recording body of permanently preserved data.

In the conventional stone monument, it was not possible to record a large amount of personal information, so the sharing of the monument was not promoted so much, but in the future, a monument, an honorable monument, and a tombstone will be shared due to soaring land. It is thought that things will increase. If the recording medium of the present invention is used and attached to the monument by an appropriate method such as fitting, it is considered that a large amount of information is recorded and the monument is shared.

By appropriately combining the color of the surface of the recording medium with the color of characters and patterns, it is possible to obtain an excellent aesthetic appearance.
