（４）モジュールとの位置決め用ピンの、ロー付を行な
う （２ケ所）。(4) Braze the positioning pins with the module (2 locations).
（５）表面のパフ掛けを行なう。(5) Puff the surface.
（６）電解脱脂を行なう。(6) Perform electrolytic degreasing.
（７）砂掛けを行なう （表面不純物の除去）。(7) Perform sanding (removal of surface impurities).
（８）遠心脱水乾燥を行なう。(8) Perform centrifugal dehydration and drying.
（９）目付けを行なう。(9) Carry out the basis weight.
（１０）塗布又は下地メッキ付を行なう。(10) Apply coating or base plating.
０１） メッキの場合はクリアコーティング処理をす
る。01) In case of plating, apply clear coating.
（１２）植表示枠の接着カシメを行なう。(12) Adhesively swage the plant display frame.
といった熟練を要する幾つもの工程を経なければならず
、作業性が悪い。This requires a number of steps that require skill, and the workability is poor.
しかも上記の工程のうち、特に（２）と（４）はモジュ
ールとの位置決め相関関係もあり、窓径の形状寸度保障
窓径に対する位置決めピンの位置間距離を、その公差範
囲に管理することは非常に困難であった。Moreover, among the above steps, (2) and (4) in particular have a positioning relationship with the module, and the distance between the positions of the positioning pins with respect to the window diameter must be managed within the tolerance range. was extremely difficult.
本発明は、上記のとおり従来の欠点を除去するためにな
されたものであり、工程を削減し、抜加工用の型製作も
不要にし、かつ品質が均一 なマスキングプレート付ガ
ラスおよびその製造方法を提供することを目的としたも
のである。The present invention was made to eliminate the drawbacks of the conventional glass as described above, and provides a glass with a masking plate and a manufacturing method thereof that reduces the number of steps, eliminates the need for making molds for punching, and has uniform quality. It is intended to provide.
以下図面に示す実施例によって本発明を詳述する。The present invention will be explained in detail below with reference to embodiments shown in the drawings.
第１図、第２図において１はガラス本体であり、斜面カ
ット２を有し、３はガラス接着面である。In FIGS. 1 and 2, 1 is a glass body having an inclined cut 2, and 3 is a glass bonding surface.
このような液晶表示腕時計の力゛ラス裏面に、本発明に
係る凹部４をダイアモンド工具型打等により形成する。The recess 4 according to the present invention is formed on the back surface of the force watch of such a liquid crystal display wristwatch by stamping with a diamond tool or the like.
ライポンＦならびに塩化第一スズ溶液により十分前処理
脱脂を行なったのち、凹部４に金、銀、銅などの蒸着物
質を、真空蒸着やスパッタリング蒸着などの方法で付与
し、蒸着膜５を形成する。After sufficient pretreatment and degreasing with Rypon F and stannous chloride solution, a vapor deposition substance such as gold, silver, copper, etc. is applied to the recess 4 by a method such as vacuum vapor deposition or sputtering vapor deposition to form a vapor deposited film 5. .
更に、ガラス本体１を陰極リングにセットしたのち、電
解浴槽に入れ、凹部４に電着金属６を成長固着させ、ガ
ラスとマスキングプレー１へを、一体的に接合形成させ
る。Further, after the glass body 1 is set in the cathode ring, it is placed in an electrolytic bath, and the electrodeposited metal 6 is grown and fixed in the recess 4, so that the glass and the masking plate 1 are integrally bonded.
真空蒸着あるいはスパッタリング蒸着後、四部４に電鋳
による電着金属層を、成長固着させる理由としては、蒸
着膜そのものの厚みが、多層コーティングを施したとし
ても、オングストローム台、また蒸着前に銀鏡処理を施
しても１ミクロン程度と、導体化処理膜自体の厚みが非
常に薄く、ガラス取付、取外しといった取扱い上で、打
コン等により膜ハガレが生じやすい。The reason for growing and fixing the electrodeposited metal layer by electroforming on the four parts 4 after vacuum deposition or sputtering deposition is that the thickness of the deposited film itself is on the angstrom range even if multilayer coating is applied, and silver mirror treatment is required before deposition. The conductive film itself has a very thin thickness of about 1 micron even if it is applied, and the film is likely to peel off due to hammering, etc. during handling such as attaching and removing the glass.
またガラス衝撃保障といった面からも、凹部４には電着
による金属充填が必要となる。Further, from the viewpoint of glass impact protection, the recess 4 needs to be filled with metal by electrodeposition.
充填用電着金属としてニッケルを要求する場合は、スル
ファミン酸ニッケルを使用し、銅を要求する場合は、酸
性硫酸銅液をそれぞ使用する。If nickel is required as the electrodeposition metal for filling, nickel sulfamate is used, and if copper is required, acidic copper sulfate solution is used.
本発明は上記のように電鋳技術を応用し、ガラスとマス
キングプレーｌ〜の一体化を計ったことにより、
（１）マスキングプレーＩ・および横表示枠等の部品製
作が不要となり、従来その製造工程で、特に要求されて
いた熟練度が必要なくなり、作業性が大幅にアップする
。The present invention applies the electroforming technology as described above to integrate the glass and the masking plate I. (1) It eliminates the need to manufacture parts such as the masking plate I and the horizontal display frame, which was previously not necessary. The manufacturing process no longer requires special skill, greatly improving work efficiency.
。（２）価格アップの大きな要因となっていた型製作費
用の排除から、製品１個当りのコストダウンに大きく寄
与できる。. (2) Eliminating mold manufacturing costs, which were a major factor in price increases, can greatly contribute to reducing the cost per product.
（３）従来のように、マスキングプレートとモジュール
との位置決めおよび位置間距離公差の管理保障が必要な
くなり、組込時の組込性が大幅にアップする。(3) It is no longer necessary to position the masking plate and the module and to manage and ensure distance tolerances between the positions, as in the past, and ease of assembly is greatly improved.
（４）マスキングプレー１〜および横表示枠の排除にと
もない、ケース総厚の薄型化に大きく貢献でき外観の見
栄えが向上する。(4) Elimination of masking play 1 and the horizontal display frame greatly contributes to reducing the total thickness of the case and improves the external appearance.
（５）製作部品点数を減少したことにより、製造日程を
大幅に省略することができるため、安くかつ大量に生産
することができる。(5) By reducing the number of manufactured parts, the manufacturing schedule can be significantly shortened, allowing for cheap and mass production.
等の顕著な諸効果を有する。It has various remarkable effects such as
