Abstract
Abstract An ink jet recording head comprises an ink path communicating with an orifice for discharging an ink, and energy-generating means for generating energy to be utilized for discharging the ink from the orifice, provided along the ink path, wherein a base member provided with the energy-generating means and a resin member provided with a recess for forming the ink path are bonded to each other while keeping the recess inside, thereby forming the ink path, and wherein a shearing bonding force between the resin member and the base member is larger than a stress generated due to a difference in coefficient of thermal expansion between the resin member and the base member.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
120 words
A process for producing an ink jet head, comprising the steps of: providing a base member having an energy-generating means for generating energy used for discharging an ink; providing a solid layer made from a removable material in a pattern corresponding to an ink path on the surface of the base member provided with the energy-generating means; arranging a mold at a side of the solid layer of the base member to form a space between the base member and the mold; charging a resin containing a plasticizer into the space to effect transfer molding, thereby bonding the resin to the base member and the solid layer; removing the mold; and removing the solid layer to form the ink path.
Claim 2
Dependent Claim
120 words
A process for producing an ink jet head, comprising the steps of: providing a base member having an energy-generating means for generating energy used for discharging an ink; providing a solid layer made from a removable material in a pattern corresponding to an ink path on the surface of the base member provided with the energy-generating means; arranging a mold at a side of the solid layer of the base member to form a space between the base member and the mold; charging a resin containing a plasticizer into the space to effect transfer molding, thereby bonding the resin to the base member and the solid layer; removing the mold; and removing the solid layer to form the ink path.
Claim 3
Dependent Claim
24 words
A process according to claim 1, further comprising the step of applying a surface treatment with a silane coupling agent onto the base member.
Claim 4
Dependent Claim
120 words
A process for producing an ink jet head, comprising the steps of: providing a base member having an energy-generating means for generating energy used for discharging an ink; providing a solid layer made from a removable material in a pattern corresponding to an ink path on the surface of the base member provided with the energy-generating means; arranging a mold at a side of the solid layer of the base member to form a space between the base member and the mold; charging a resin containing a pigment into the space to effect transfer molding, thereby bonding the resin to the base member and the solid layer; removing the mold; and removing the solid layer to form the ink path.
Claim 5
Dependent Claim
120 words
A process for producing an ink jet head, comprising the steps of: providing a base member having an energy-generating means for generating energy used for discharging an ink; providing a solid layer made from a removable material in a pattern corresponding to an ink path on the surface of the base member provided with the energy-generating means; arranging a mold at a side of the solid layer of the base member to form a space between the base member and the mold; charging a resin containing a pigment into the space to effect transfer molding, thereby bonding the resin to the base member and the solid layer; removing the mold; and removing the solid layer to form the ink path.
Claim 6
Dependent Claim
24 words
A process according to claim 3, further comprising the step of applying a surface treatment with a silane coupling agent onto the base member.
Claim 7
Dependent Claim
13 words
A process according to claim 3, wherein the resin further comprises a plasticizer.
Claim 8
Dependent Claim
23 words
A process according to claim 5, further comprising the step of treating the surface of the base member with a silane coupling agent.
