Abstract: A thick-film sheet member provided by a thick film which has a predetermined thickness and a predetermined thickness and a predetermined plan configuration, without the thick film being fixed to a substrate. This thick-film sheet member can be produced by (a) forming a paste film having a predetermined thickness, on a predetermined film formation surface in a predetermined pattern, and (b) peeling the paste film from the predetermined film formation surface after subjecting the paste film to a firing treatment effected at a predetermined temperature. The paste film is constituted by a thick-film material in the form of particles which are bonded together with a resin and which are sintered at the predetermined temperature.

Abstract: A thick-film sheet member producing method including: (a) a support-body preparing step of preparing a support body having a film formation surface provided by a particle layer constituted by high-melting-point particles which are held together with a resin and which have a melting point higher than a predetermined temperature; (b) a paste-film forming step of forming a paste film on the film formation surface, by applying a paste onto the film formation surface; and (c) a firing step of subjecting the support body on which the paste film has been formed, to a heat treatment effected at the predetermined temperature, so as to burn the resin included in the particle layer, whereby the high-melting-point particles become unbound from each other in absence of the resin that has been burned. The paste film is sintered in the firing step, whereby a thick film is formed of the sintered paste film.

Abstract: In an AC plasma display panel having a glaze layer covering address electrodes, a proper amount of conductive filler is introduced into the glaze layer, to lower the volume resistivity of the glaze layer. Thus, generation of spark discharge can be suppressed in driving the display panel.

Abstract: According to the present invention, an oxygen concentration detector includes a housing, a detecting element inserted into said housing and a cover for covering a top portion of said detecting element. The detecting element is made of solid electrolyte and includes an atmospheric chamber therein. The cover includes an air vent portion for introducing air into said atmospheric chamber of the detecting element. The detecting element includes an air introducing path open to the atmospheric chamber at a side wall of the detecting element. It is possible to provide an oxygen concentration detector capable of introducing the air into the atmospheric chamber and maintaining an oxygen concentration in the atmospheric chamber at the same level as an atmosphere constantly.

Abstract: A winding apparatus for winding a coated wire on the drum for making a coil which is used for a stator or an alternator. A sectional shape of the wire which is introduced to the winding apparatus is circular, and the wire is deformed in order to make the sectional shape of the wire polygonal, so that the polygonal wire is fed to the bobbin in order to be wound on the bobbin. The resulting coil wound by the apparatus has an increased density.
