  • METHOD OF PRODUCING AN ELASTIC PLATE MEMBER FOR A LIQUID JET HEAD
    Publication number: 20130242002
    Abstract: A method for producing an elastic plate for a liquid jet head, which includes etching a rolled metal plate based on a rolling direction of the rolled metal plate, to form an etched portion and a non-etched portion on the rolled metal plate. The thickness of the etched portion is thinner than the thickness of the non-etched portion and the rolling direction is substantially perpendicular to a long side of the rolled metal plate.

  • MANUFACTURING METHOD OF A LIQUID EJECTING HEAD AND A LIQUID EJECTING APPARATUS WITH SAID HEAD
    Publication number: 20090165300
    Abstract: A liquid ejecting head which has a first substrate and a second substrate having a burr resulting from press working formed at one side thereof is manufactured by the first joining step of joining the first substrate to the non-burred other side of the second substrate and the second joining step of disposing a sheet for protecting the shape of the burr on one side of the second substrate and joining the second substrate and the first substrate joined in the first step by holding between pressing members in such a manner that the sheet is in contact with the burr.

  • Method of producing an elastic plate for an ink jet recording head
    Publication number: 20070067991
    Abstract: A plate member constituting a channel unit of an ink jet recording head has a metal plate which is produced by rolling an etchable material, and a polymer film which is laminated onto one face of the metal plate. The long side is perpendicular to the rolling direction of the metal plate. Warpage which easily occurs in the longitudinal direction is suppressed by the rigidity which is large in a direction perpendicular to the rolling direction.

  • Method of producing an elastic plate for an ink jet recording head
    Patent number: 7159315
    Abstract: A method of producing an elastic plate for an ink jet recording head is provided. In one implementation, the method laminates and bonds a deformable metal plate or polymer film and a rolled metal plate. Also, the method etches the rolled metal plate based on a rolling direction of the rolled metal plate to form a through hole serving as an elastically deformable region.
