Abstract: Gas manifolds which are excellent in both phosphoric acid proof and electric insulation and which have sufficient corrosion proof over a long period are provided. A resin sheet with high phosphoric acid proof is folded to have a size smaller than that of the corner sections of the inner plane of gas manifolds by the size corresponding to a thermal expansion, and the folded planes are thermally compressed in air tight to form box-shaped linings. These linings are applied to the inner planes of the gas manifolds. Patches are thermally compressed to the outer surface of the bottom section of the linings and each patch is fitted loosely with a male hook or a female hook. A female hook or a male hook for engaging with the hook on each patch is fitted on the inner plane of the gas manifolds at an opposing position. The linings can be fixed to the gas manifolds engageably and disengageably by these hooks.

Abstract: In a method for winding a toroidal coil, a winding of a first layer is made by means of repeating the following three steps. At a first step, one end of a wire is inserted into a central aperture of a core from one side thereof to extend the wire along an axial direction of the core; the other end of the wire is abutted to one surface of the core such that the other end is radially extended; and a tension is applied to the wire and the core with the other end of the wire is then turned in a diametrical direction of the core perpendicular to the radial direction. At a second step, the one end of the wire is inserted into the central aperture of the core towards the other side; and the tension is applied to the wire and the core is then rotated at a desired angle in one direction on a central axis of the core.

Abstract: In a color image display apparatus, light beams intensity modulated by a green color image signal are deflected by an ocillating mirror, and then focused on a photo-conductive layer (PCL) member of a light-written type spacial light modulation element (SLM) through two focusing lenses for light write operation. Light beams intensity modulated by a time-axis compressed time-divisional image signal of two remaining colors (red and blue) are deflected by another mirror oscillated simultaneously with the ocillating mirror, and then focused on a PCL member of a SLM of the same type through two focusing lenses for light write operation. A read light beam is resolved into the light of the green wave length band and the lights of red and blue wave length bands, respectively, and then given to the SLMs, respectively for light read operation. The two read light beams reflected by the SLMs are synthesizing, and then projected on a screen through a common projection lens.

A reading light beam emitted from a light source is separated into three color beams, e.g., Red, Green and Blue color beams through a tri-color separation and composition optical system. The separated color beams are irradiated on image forming devices provided correspondingly with Red, Green and Blue color images to read out color images respectively therefrom. Each of the reflected light beams from the image forming device carrying color image information impinges again on the tri-color separation and composition optical system to compose a composite image beam. The composite image beam is projected on the screen through an optical lens system comprising a first lens group, a second lens group and a third lens group disposed along an optical axis in order.
