摘要:
A process for producing an ink jet head, including forming an ink flow path pattern whose surface has been subjected to insolubilization treatment on a substrate having an energy-generating element, applying a UV curable flow path forming material on the pattern and substrate to form an ink flow path forming layer, irradiating part of the ink flow path forming layer with ultraviolet rays for development, thereby forming an ink ejection orifice, and removing the pattern, thereby forming an ink flow path. The step of forming the pattern includes applying a positive resist containing a resin having a phenolic hydroxyl group on the substrate to form a positive resist layer, patterning the positive resist layer to form an ink flow path pattern prior to insolubilization treatment, applying a coating agent containing a compound having two vinyl ether groups on the pattern, and heat-treating the pattern coated with the coating agent.

The present invention provides a method for manufacturing a high quality ink jet head in which, in a case where a coating resin layer constituting ink flow path walls is formed, even when a solvent having a strong dissolving force is used, it is not feared that a configuration of an ink flow path pattern is distorted. In the method, a photosensitive resin composition layer in which an inter-molecule bridging reaction proceeds by irradiation of an ionization radiant ray having a first wavelength band and a molecule decaying reaction of main chain decomposing type of the resin proceeds by irradiation of an ionization radiant ray having a second wavelength band different from the first wavelength band is formed on a substrate on which energy generating elements were provided. Thereafter, an ink flow path pattern is formed by the irradiation of the ionization radiant ray having the first wavelength band and a developing process. Then, a coating resin layer constituting ink flow path walls is formed on the ink flow path pattern. After ink discharge ports are formed, the photosensitive resin composition layer forming the ink flow path pattern is dissolved and removed by irradiating the ionization radiant ray having the second wavelength band.

A seam welding apparatus enables, even when metallic sheets are arranged in a line in a short distance, the welding electrodes to come into contact only with the metallic sheet to be welded, so as to provide a reliable welding of the metallic sheets to form connected portions having high strength. The roller electrode 20, which has on its outer peripheral portion the conical electrode surface 21, is supported by the central axis inclined relative to the surface of the metallic sheet 50 to be welded, and there is provided the stationary electrode 30 in which the portion including the flat electrode surface 31 has the smaller thickness. The electrode surface 21 of the roller electrode 20 is brought into contact with the surface of one of the metallic sheets 50 to be welded, while bringing the electrode surface 31 of the stationary electrode 30 into contact with the surface of the other metallic sheet 50. It is possible to prevent interference of the roller electrode 20 and the stationary electrode 30 with the metallic sheet 50, which is not currently subjected to the welding, and to hold firmly the metallic sheet 50 to be welded by the roller electrode 20 and the stationary electrode 30 to perform the seam welding.
