    摘要： A method of forming a metal pattern comprising forming a metal film having a lower layer made of a metal and an upper layer made of a metal different from the metal of the lower layer, forming a resist film having a predetermined pattern on the upper layer, and patterning the metal film by etching the metal film using the resist film as a mask. Here, patterning the metal film comprises etching the upper layer, immersing the resist film and the upper layer in a pretreatment liquid containing a nonionic surfactant after the first etching process, and etching the lower layer after the immersing process.

    摘要： A male die for forming a member incorporated in a liquid ejection head is disclosed. Each of a plurality of first forging punches is operable to form a first recess on a metal plate. 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.

    摘要： An object is to provide a fine forging method for forming partitions of recesses precisely and forming recess shapes for pressure generation chambers etc. with high accuracy as well as a liquid ejection head that is produced by using the fine forming method. A fine forging method for forming groove-shaped recesses that are arranged at a prescribed pitch. After groove-shaped recesses are formed tentatively in a material plate by a first punch in which tentative forming punches are arranged, finish forming is performed on the tentatively formed groove-shaped recesses by using a second punch in which finish forming punches are arranged. An end portion of a projection strip is formed with slant faces or a slant face, whereby an end portion of each groove-shaped recess is formed precisely. A liquid ejection head produced by the above method exhibits stable liquid ejection characteristics and its manufacturing cost can be reduced by virtue of simplified working of forging.

    摘要： There is disclosed a punch for forging a metallic plate member. A first die is adapted to be opposed to a first face of the plate member. A second die is adapted to be opposed to a second face of the plate member. A plurality of first projections are provided on the first die and arranged in a first direction with a fixed pitch. Each of the first projections is elongated in a second direction perpendicular to the first direction. A plurality of second projections are provided on the second die and arranged in the first direction with the fixed pitch. Each of the second projections is elongated in the second direction and provided with a concave portion extending in the second direction at a distal end portion thereof. The plate member is sandwiched between the first die and the second die so that the first projections and the second projections are cut into the plate member in a third direction orthogonal to the first direction and the second direction, to perform a first forging work.
