Abstract
Abstract An orifice plate for a jet drop recorder is fabricated by plating techniques. It is formed throughout of a single, homogeneous material, such as nickel, for compatibility with the recorder ink, and is of sufficient thickness to provide adequate strength. The orifices are open on both sides for easy cleaning.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
128 words
A method of producing a solid orifice plate adapted for use in a jet drop recorder, comprising: (a) forming a resist peg on a substrate to define an orifice recess, (b) plating the substrate around the sides of the peg to form the orifice recess and over the peg to form an orifice smaller than the recess over the peg, (c) forming a resist plug larger than the orifice over the orifice to define a cavity on the side of the orifice opposite the recess, (d) plating the substrate again around the sides of the plug to thicken the orifice plate and to form the cavity, and (e) removing the resist and substrate to leave an orifice plate having an orifice disposed between the recess and the cavity.
Claim 2
Independent Claim
128 words
A method of producing a solid orifice plate adapted for use in a jet drop recorder, comprising: (a) forming a resist peg on a substrate to define an orifice recess, (b) plating the substrate around the sides of the peg to form the orifice recess and over the peg to form an orifice smaller than the recess over the peg, (c) forming a resist plug larger than the orifice over the orifice to define a cavity on the side of the orifice opposite the recess, (d) plating the substrate again around the sides of the plug to thicken the orifice plate and to form the cavity, and (e) removing the resist and substrate to leave an orifice plate having an orifice disposed between the recess and the cavity.
Claim 3
Dependent Claim
25 words
The method of claim 1 wherein both said plating steps further comprise plating the substrate with the same material for forming a homogeneous orifice plate.
Claim 4
Dependent Claim
21 words
The method of claim 2 wherein said plating steps further comprise plating with nickel for forming a solid nickel orifice plate.
Claim 5
Dependent Claim
25 words
The method of claim 1 wherein said first plating step further comprises plating inwardly across the top edges of the peg to form the orifice.
Claim 6
Dependent Claim
32 words
The method of claim 1 wherein said forming steps further comprise forming a substantially cylindrical peg and a substantially cylindrical plug for forming a substantially cylindrical recess and a substantially cylindrical cavity.
Claim 7
Dependent Claim
13 words
A solid, homogeneous, metallic orifice plate produced by the method of claim 1.
Claim 8
Independent Claim
152 words
A method for producing a solid nickel orifice plate adapted for use in a jet drop recorder, comprising: (a) forming a substantially cylindrical resist peg on a substrate to define a substantially cylindrical orifice recess, (b) plating the substrate with nickel around the sides of the peg and inwardly across the top edges thereof to form the orifice recess and to form an orifice smaller than the recess over the peg, (c) forming a substantially cylindrical resist plug over the orifice to define a substantially cylindrical cavity on the side of the orifice opposite the recess, the plug and cavity being larger than the peg and recess, (d) plating the substrate again with nickel around the sides of the plug to thicken the orifice plate and to form the cavity, and (e) removing the resist and substrate to leave an orifice plate having an orifice disposed between the recess and the cavity.
Claim 9
Independent Claim
152 words
A method for producing a solid nickel orifice plate adapted for use in a jet drop recorder, comprising: (a) forming a substantially cylindrical resist peg on a substrate to define a substantially cylindrical orifice recess, (b) plating the substrate with nickel around the sides of the peg and inwardly across the top edges thereof to form the orifice recess and to form an orifice smaller than the recess over the peg, (c) forming a substantially cylindrical resist plug over the orifice to define a substantially cylindrical cavity on the side of the orifice opposite the recess, the plug and cavity being larger than the peg and recess, (d) plating the substrate again with nickel around the sides of the plug to thicken the orifice plate and to form the cavity, and (e) removing the resist and substrate to leave an orifice plate having an orifice disposed between the recess and the cavity.
