    摘要： An apparatus of fabricating a liquid ejection head is provided. The apparatus includes: a first die including projected streak portions aligned in parallel by a predetermined pitch and gap portions formed between the adjacent projected streak portions, wherein the first die is adapted to form the groove-like recess portions by pressing the projected streak portions to a metal plate; and a second die for supporting the metal plate to which the projected streak portions of the first die are pressed. Each of the projected streak portions includes: an inner wall forming portion for forming an inner wall of the corresponding groove-like recess portion extending in a depth direction of the corresponding groove-like recess portion; a connecting face portion; and an inclined face portion, continuous via the connecting face portion to the inner wall forming portion, for forming a bottom portion of the corresponding groove like recess portion into a substantially V-like shape.

    摘要： [Object] To provide a method for manufacturing a scale having an improved abrasion resistance, the scale, and an encoder having the same.[Solving Means] A scale base material 17 is arranged on the upper surface of a mount 26. A pattern base material 18′ as a material of pattern portions 18 are laminated on the upper surface of the scale base material 17. In this laminated state, the pattern base material 18′ is punched toward the scale base material 17 via a press work. Accordingly, the punched pattern base material 18′ is embedded and held in a thickness of the scale base material 17, and the pattern portions 18 are formed.

    摘要： There is provided a first die, in which a plurality of projections are arrayed in a first direction with a fixed pitch to form at least one array of the projections. Each of the projections is elongated in a second direction perpendicular to the first direction. The first die faces a first face of the plate member. A second die is opposed to the first die while supporting a second face of the plate member. At least one first region is formed on the plate member so as to have a less rigidity than another region of the plate member. The first die and the second die are approached so that the projections are dug into a second region in the first face of the plate member, thereby forming partitioned recesses to be pressure generating chambers of a liquid ejection head. The at least one first region is adjacent to at least one of ends in the first direction of the second region, such that the first region and the second region are arranged in the second direction.

    摘要： A metallic plate member having at least one through hole to be a part a common liquid reservoir of a liquid ejection head is provided. In a first die, a plurality of first projections are arrayed in a first direction with a fixed pitch. Each of the first projections is elongated in a second direction perpendicular to the first direction. The plate member is mounted on a second die, and a regulating member is inserted into the through hole. The first projections are pressed against a first region in a first face of the plate member which is adjacent to the through hole in the second direction, so as to generate a plastic flow of a material in the plate member into gaps defined between the first projections, while the plastic flow is regulated by the regulating member. A plurality of recesses formed by the first projections and a plurality of partition walls formed by the material flown into the gaps constitutes a part of the pressure generating chambers.

    摘要： A cylindrical rod 20 is formed by bending sheet metal 10 so as to bond together a pair of edges 12 and 14 of the sheet metal 10. The cylindrical rod 20 includes therein (i) convex portions 16 each of which protrudes from the edge 12 and includes a sub-portion whose width is larger at a side thereof more distant from the edge 12 than at a side thereof less distant from the edge 12, and (ii) concave portions 18 which are formed on the edge 14, have a shape complementary to the shape of the convex portions 16, and are fitted into the convex portions 16. A cylindrical rod which has high circularity and high linearity, in other words, which hardly has vertical and horizontal curves can be provided.
