    摘要: To supply electromotive force to a solid semiconductor element in an ink tank in a non-contact and stable manner. An electromagnetic apparatus (a standstill electromotive force supply unit) is placed at a home position HP. When a carriage is at a standstill at this home position HP, if the electromagnetic apparatus is AC-driven, magnetic properties of both ends (magnetic poles) continue to change mutually and penetrate a solid semiconductor element in the ink tank on the carriage so that a constantly changing magnetic flux is generated. Electromotive force is generated by electromagnetic induction on a coil of the solid semiconductor element. In addition, if the carriage reciprocates during printing operation, the coil L of the solid semiconductor element crosses inside the magnetic flux due to a plurality of permanent magnets (a movement time electromotive force supply unit) arranged on a carrier path (range of movement), and so the electromotive force is generated on the coil by electromagnetic induction. Such electromotive force is converted into energy for activating and operating the solid semiconductor element.

    摘要: A method for manufacturing ink jet recording heads includes the steps of forming a film of a first inorganic material in the form of ink flow path pattern using a soluble first inorganic material on the substrate having ink-discharge, pressure-generating elements formed thereon, forming a film of a second inorganic material becoming ink flow walls on the film of the first inorganic material using the second inorganic material, forming ink-discharge openings on the film of the second inorganic material above the ink-discharge, pressure-generating elements, and eluting the film of the first inorganic material. With this method, it becomes possible to set the ink-discharge, pressure-generating elements and the ink-discharge openings (ports) of each head with extremely high precision in a shorter distance with a good reproducibility to record images with higher quality and without any deformation of the head due to the applied heat, while providing a good resistance to ink and erosion, as well as a higher dimensional precision and reliability that may be affected otherwise by swelling or the like.
