Abstract
A stimulator for a continuous ink jet print head is fabricated by providing a surface roughness of between 100 and 200 microinches on the surface of the stimulator body and attaching a piezoelectric transducer strip to the body using an acrylic cement having a viscosity of between 2 and 100 centipois. The resulting stimulator exhibits improved lifetime with acceptable acoustic properties.
Claims6
A stimulator for an ink jet print head, comprising:
- (a) a body of high acoustic Q material having a surface finish in the range of 100 to 200 microinches RMS;
- and
- (b) a plurality piezoelectric strips attached to said body by an acrylic cement-having an uncured viscosity of between 2 and 100 centipois.
A method of making a stimulator for continuous ink jet print head, comprising the steps of:
- (a) providing a body of high acoustic Q material;
- (b) treating the surface of said body to produce a finish having a roughness of 100 to 200 microinches RMS;
- (c) providing a plurality of piezoelectric strips;
- and
- (d) attaching said strips to said surface with an acrylic cement having a viscosity of between 2 and 100 centipois.
