Abstract: A double-sided luminous compound substrate is disclosed. The double-sided luminous compound substrate comprises: a first transparent substrate, having a plurality of first conductors parallel disposed on a surface thereof, and a plurality of parallel-disposed second conductors overlapping the first conductors, each first conductor having a plurality of emitters equidistantly disposed thereon and electrically connected thereto; a second transparent substrate, disposed parallel to and opposite to the first transparent substrate, further comprising a fluorescence layer formed on the side facing the first transparent substrate; and a plurality of spacers, disposed between the first and second transparent substrates.

Abstract: A method for manufacturing an electrode plate with improved reliability, comprising: (a) providing a glass substrate; (b) spreading an Indium Tin Oxide (ITO) layer on a specific area of the glass substrate; (c) exposing and developing the ITO layer; and (d) screen printing at least a thick film conductive layer on the ITO layer.

Abstract: An improved shield of belted wheel of a compound machine comprises mainly a slide hole disposed at an appropriate location of upper portion thereof and a slide cover positioned correspondingly to the slide hole. The slide cover is characterized in that it comprises two rails located at lateral sides of bottom surface thereof to permit the slide cover to move along the confines of the slide hole in such a way that there is a sufficient open space in the slide hole to allow the shield to be lifted through the main shaft. The shield can be therefore opened up and closed with ease and speed.
