Description
一部の所定領域は、ひげ玉の貫通孔を挟み接続部と対向する領域であってもよい。 Some of the predetermined area may be an area facing the connecting portion sandwiched holes beard ball.
また、レーザ照射工程の後に、ひげぜんまいをエッチング液に浸漬させてエッチングするウェットエッチング工程を設けるようにしてもよい。Further, after the laser irradiation process, a wet etching process may be provided in which the hairspring is immersed in an etching solution for etching.
また、ひげぜんまいと結晶構造の異なる保護膜を形成する保護膜形成工程と、保護膜を部分的に除去するトリミング工程と、を備えるようにしてもよい。Moreover, you may make it provide the protective film formation process which forms the protective film from which a balance spring and a crystal structure differ, and the trimming process which removes a protective film partially.
本発明のひげぜんまいは、回転軸体と嵌合するための貫通孔を有するひげ玉と、ひげ玉と接続部で接続し、貫通孔を中心にしてひげ玉に巻回されるコイル形状のぜんまい部と、を備える、所定の結晶構造を有する材料からなるひげぜんまいであって、一部の所定領域の結晶構造は、他の領域の結晶構造と異なっていることを特徴とする。The hairspring of the present invention is a hairspring having a through-hole for fitting to a rotating shaft body, a coil-shaped spring that is connected to the whiskball at a connection portion and wound around the hairball around the through-hole. And a balance spring made of a material having a predetermined crystal structure, wherein the crystal structure of some predetermined regions is different from the crystal structure of other regions.
一部の所定領域は、ひげ玉の貫通孔を挟み前記接続部と対向する領域であってもよい。A part of the predetermined region may be a region facing the connection part with the through hole of the whisker ball interposed therebetween.
一部の所定領域をひげ玉の貫通孔を中心とした角度θで表したとき、θは、１８０度以下であることが望ましい。When a part of the predetermined region is expressed by an angle θ with the through hole of the whisker ball as the center, θ is desirably 180 degrees or less.
さらに、角度θは、約９０度であることが望ましい。Further, the angle θ is preferably about 90 degrees.
また、一部の所定領域の結晶構造が晶質であり、他の領域の結晶構造が非晶質であってもよい。Further, the crystal structure of some predetermined regions may be crystalline, and the crystal structure of other regions may be amorphous.
また、一部の所定領域の結晶構造が非晶質であり、他の領域の結晶構造が晶質であってもよい。Further, the crystal structure of some predetermined regions may be amorphous, and the crystal structure of other regions may be crystalline.
ひげぜんまいと結晶構造の異なる保護膜を、ひげぜんまいの表面に設け、保護膜が除去されたトリミング領域を有していてもよい。A protective film having a crystal structure different from that of the hairspring may be provided on the surface of the hairspring, and the trimming region from which the protective film is removed may be provided.
