Abstract
Abstract The present invention provides a method for manufacturing a liquid jet recording head, comprising the steps of providing a liquid jet recording head sub-assembly; polishing a surface of the sub-assembly on which the discharge openings are to be formed; and removing the filler from the liquid passages. Method further comprises a step of curing the filler to become harder than the pencil hardness H before the polishing step. The present invention further provides a liquid jet recording head manufactured by the above method, and a liquid jet recording apparatus including such recording head.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
100 words
A method for manufacturing a liquid jet recording head, comprising the steps of providing a liquid jet recording head sub-assembly by forming a liquid passage wall forming member for forming walls of liquid passages communicating with respective liquid discharge openings between a substrate and a lid plate and by filling a filler into said liquid passages; polishing a surface of said sub-assembly on which said discharge openings are to be formed; and removing the filler from said liquid passages, characterized by that a step of curing said filler to become harder than the pencil hardness H before said polishing step.
Claim 2
Dependent Claim
64 words
A method for manufacturing a liquid jet recording head according to claim 1, wherein said filler comprises a solid layer made of resin soluble to a removing liquid, said liquid passage wall forming member is disposed to cover said solid layer and is made of active energy ray curable material, and said lid plate is made of material permeable to the active energy rays.
Claim 3
Dependent Claim
57 words
A method for manufacturing a liquid jet recording head according to claim 1, wherein said liquid passage wall forming member comprises photosensitive compound, and said filler comprises material which can be filled in said liquid passages after said substrate, said liquid passage wall forming member and said lid plate were laminated and which can be solidified later.
Claim 4
Dependent Claim
13 words
A liquid jet recording head manufactured by the method according to claim 1.
Claim 5
Dependent Claim
13 words
A liquid jet recording head manufactured by the method according to claim 2.
Claim 6
Dependent Claim
13 words
A liquid jet recording head manufactured by the method according to claim 3.
Claim 7
Dependent Claim
33 words
