Title: Ink jet recorder
Inventor: MATSUMOTO SHUZO
IPC: B41J2/05
Filed: 1989-12-15
Abstract: PURPOSE:To make regulation of a focus position of irradiation with electromagnetic wave energy needless by a method wherein a flat microlens is formed in a substrate glass forming a part of a recording ink chamber corresponding to a heating part. CONSTITUTION:Parallel light obtained by passing through a coupling lens 7 is focused in recording liquid 2 with a flat microlens 6, and an ink liquid is discharged. Since the lens exists directly in a substrate forming a part of a liquid chamber and a passage at that time, a focus position is determined by formation of the microlens 6. Therefore, complex regulating operation for focusing in specified liquid becomes needless, and a stable characteristic with no dispersion is easily obtained. The flat microlens 6 is generally arranged on one or a plurality of straight lines so as to be made to correspond to a heating part of ink. An arranging pitch of the heating part should preferably conform to a printing dot pitch and therefore, a lens form of the flat microlens should suitably be 10-50 mum. Thereby, it can be also so formed as to comply with a paper surface in a matrix state manner.

IPC: G02B3/00
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To control the size of a microlens by forming a fluidity controlling layer all over a low melting point glass layer and melting the low melting point glass layer by heating to form a microlens. SOLUTION: A diffusion preventing layer 2 is formed on a supporting substrate 1, and a low melting glass layer 3 is formed thereon. A photosensitive resist coating film 4 is applied to form a resist pattern 5. The pattern is used as a mask for etching to form grooves 6 in the low melting point glass layer 3. Then a fluidity controlling layer 8 is formed all over the low melting point glass layer 3. As for the fluidity controlling layer 8, a photosetting or thermosetting resin which can be ashed at the calcining temp. of the low melting point glass is used. The substrate 1 is calcined at a temp. higher than the softening point of the low melting point glass layer 3 and lower than the softening point of the substrate 1. When the low melting point glass layer 3 flows by melting, the fluidity controlling layer 8 suppresses the layer 3 from spreading.  The fluidity controlling layer 8 disappears by ashing and microlens 9 are formed.
