摘要： There is disclosed a method of manufacturing a chamber formation plate of a liquid ejection head. The chamber formation plate includes a first region formed with at least recess portions to be pressure generating chambers communicated with nozzles from which liquid droplets are ejected by pressure generated in the pressure generating chambers. A metal plate and a forging die are provided. A reference part is provided on the metal plate. The reference part defines a relative position between the first region and the forging die. At least one deformation absorber is provided at a second region of the metal plate where is between the first region and the reference part. At least one plastic working is performed by the forging die, with respect to the first region to form at least the recess portions, while plastic deformation of the metal plate caused by the plastic working is absorbed by the deformation absorber.

摘要： A method and apparatus for the precise manufacture of high quality, four-sided electrical contacts by means of a closely controlled material skiving process. The apparatus is designed so that the starting material from which the four-sided electrical contacts are made is closely constrained in the area of the shear boundaries so that predictable and precisely controlled shearing of the material can repeatedly be achieved to initially form four precursor sides, two of which are arcuate. The apparatus also includes sequentially operating forming mechanisms for precisely forming the precursor sides of the precursor contact into a final end product configuration.

摘要： Methods for manufacturing a press formed article (22) may include half die cutting a substantially flat material (1, 10) by press forming, thereby forming a first processed material (10null) having a first intermediate press formed article (16) defined therein. The half die cutting step is preferably performed while simultaneously compressing the central portion of the material in order to induce outward plastic flow within the first intermediate press formed article. These methods optionally may include pressing the first intermediate press formed article back into the first processed material, thereby forming a second processed material (10null) having a second intermediate press formed article (20), and separating the second intermediate press formed article from the second processed material, thereby forming a final processed material (10nullnull) and an unfinished press formed article (22null).

摘要： A compound indenter for metal coldwork, and a method of employing such tooling. The compound indenter tool is used to produce deformation in a workpiece structure, to provide a selected beneficial residual stress profile in the workpiece, in order to provide high fatigue life structures in a minimum number of manufacturing steps. Preferably, action of a compound indenter causes deformation of the workpiece, causing dimples in the workpiece. By optimized use of the method, a relatively uniform beneficial residual stress profile is provided at both the surface and at the midplane apertures in a workpiece, so as to improve overall fatigue life. An improved, compound indenter tool profile shape is described, having a first, elongate indenter with a shaped indenter surface portion, and a second shaped indenter surrounding the first indenter and forming an annular shoulder recessed from the surface portion of the first indenter. Additionally, a foot having a bottom portion can be used to confiningly surround the second indenter during application of force to the surface of a workpiece, to prevent surface deformation.

摘要： A bond tool is used in semiconductor package to break a lead at a notch formed thereon and then bonds the broken lead to a die pad. In an embossing-type bond tool, an end thereof is provided with a projected portion for vertically pressing against the lead to form a transversely extended groove thereon. In a scissor-type bond tool, an end thereof is formed into two opposite sharp blades for horizontally cutting the lead at two lateral edges thereof to provide two symmetrical cuts. Unlike the conventional notches that are formed on the lead during the complicate forming process of the lead, the groove and the symmetrical cuts are easily formed on the straight lead without notch to provide a weak point at reduced manufacturing cost. The difficulties in forming the conventional notches on the lead due to the highly precise lead windows, lead width, and lead pitch can therefore be avoided and thus improve the yield for manufacturing of lead bond substrates.
摘要翻译：在半导体封装中使用焊接工具在其上形成的缺口上断开引线，然后将断开的引线键合到管芯焊盘。在压花型粘接工具中，其端部设置有用于垂直压靠引线的突出部分，以在其上形成横向延伸的凹槽。在剪刀式粘合工具中，其端部形成为两个相对的锋利刀片，用于在其两个侧边缘处水平切割引线以提供两个对称的切口。与在引线的复杂形成过程中在引线上形成的常规凹口不同，凹槽和对称切口容易形成在没有凹口的直引线上，以降低制造成本来提供弱点。因此，可以避免由于高精度的引线窗，引线宽度和引线间距而在引线上形成常规凹口的困难，从而提高了引线接合基板的制造成品率。

The first forging punches are arranged at a fixed pitch to form a punch row in a first direction. Each of a plurality of second forging punches is operable to form a second recess on the metal plate. The second forging punches are arranged adjacently to first forging punches located at both ends of the punch row. The first recess is to be a first part of the member which is used to eject liquid from the liquid ejection head, and the second recess is to be a second part of the member which is not used to eject liquid.

The passive-adaptive indentor has a first member that includes a first working end that is configured to create a first residual stress field that extends to a predetermined depth in the material. The passive-adaptive indentor also has a second member that includes a second working end that is configured to create a second residual stress field that extends to a generally fixed second depth of the material regardless of the depth to which the first residual stress field extends. A method of using a passive-adaptive indentor for cold working a material is also presented.

摘要： An apparatus for producing optical aperture is disclosed. A pressing body has a plane covering a tip and at least a part of stoppers. An opaque film formed on the tip. The pressing body is displaced toward the tip for forming an aperture on a point of the tip. According to the apparatus, the amount of displacement of the plate can be controlled excellently by the stopper and can be made very small. Thus, the aperture having a uniform and small size can be produced on the point of the tip easily.
