An image transmitting element and process for producing a photo-shield spacer plate used for the image transmitting element are disclosed. The image transmitting element comprises: a lens array plate comprising micro-lenses one-dimensionally or two-dimensionally formed as an array on a transparent substrate; and a photo-shield spacer plate joined with the lens array plate on one surface thereof, the photo-shield spacer plate comprising an array of photo-transmissible holes formed therein each corresponding to the micro-lenses, respectively, at least a part or the whole of an inner wall of each of the photo-tranmissible holes being a photo-absorptive surface, the photo-shield spacer plate comprising a pair of members each having grooves each forming a longitudinally divided half of the respective photo-transmissible holes, the pair of members being joined and contact with each other so that the grooves of one of the pair of members are made to accord with the grooves of the other of the pair of members so as to form the photo-transmissible holes.

Image transmitting element and process for producing photo-shield spacer

A method for forming a coating of a desired pattern on the surface of a substrate which comprises covering the substrate surface with a sheet-like mask having openings corresponding to the desired pattern and directing a film-forming substance from a source toward the substrate surface through the mask, wherein relative to a press member having at least one slit with a width w.sub.2 sufficiently smaller than the width w.sub.1 of the substrate, the substrate and the mask in the superimposed state are moved in at least the widthwise direction of the slit, said press member being urged against the mask to secure close adherence between the mask and the substrate, and the film-forming substance is directed toward the substrate through the slit of the press member during this relative movement.

Method for forming patterned coating

A humidity-sensitive sensor, especially useful on the window of an automobile with the sensor on the inside surface of the glass. The sensor has a pair of spaced electrodes and a humidity-sensitive coating composed of a hydroscopic resin extending over the pair of electrodes. The resin can be an acrylate resin or a methacrylate resin, and preferably is a resin which has a volume change of at least 10% in response to a 50% change in humidity. Dispersed in the resin are electrically conductive particles, preferably in an amount of from 20 to 60% by volume of the amount of resin. The sensor, prior to its use in an operating device, is preferably exposed to a high humidity condition and a low humidity condition at least thirty times in order to stabilize it.
