The invention relates to a multi-component chlorine dioxide producing system. The invention produces effective amounts of chlorine dioxide in five minutes or less without instantaneous production or loss of chlorine dioxide. The invention further includes a dispensing apparatus to allow for the dispensing of the multi component system to allow for insitu production of chlorine dioxide.

The present invention provides a transflective liquid crystal display device which includes diffusion reflective electrodes suitable for a display of high definition. Into an organic resin film material PET which is formed by mixing NQD as a photosensitive agent in an acrylic resin having a specific gravity of 1.05 and a refractive index of 1.50, spherical particles PTC made of acrylic modified polystyrene which has a specific gravity of 1.00, a refractive index of 1.50 and a particle size of 1.6 μm are mixed at a rate of 3:1 so as to form an organic insulation film material in which a total solid content is adjusted to 30% and viscosity is adjusted 20 mPa·s. The organic insulation film material is applied and is dried to form an organic insulation film. A portion of the organic insulation film which is to be arranged below a diffusion reflective electrode is exposed using an exposure mask having half exposure apertures which are formed of a large number of slits and the organic insulation film is hardened. Aluminum is sputtered to the organic insulation film and is subject to photolithography etching treatment thus forming the diffusion reflective electrodes MT in a reflective region. A reflective region of the diffusion reflective electrode MT has an uneven surface shape which traces uneven surface shapes of the spherical particles PTC mixed into the organic insulation film PF arranged below the diffusion reflective electrodes MT.

An image display device includes phosphor layers which are formed on an inner surface of a light transmitting face plate, a black matrix film which is formed on the inner surface of the face plate in a state that the black matrix film defines the phosphor layers into phosphor layers of respective colors, and electron beam sources which are arranged in the inside of the evacuated envelope in a state that the electron beam sources face the phosphor layers in an opposed manner and irradiates electron beams to the phosphor layers. An area occupying ratio of the black matrix film as viewed from an image display screen side of the face plate is set within the range of 60% to 95%.

A high contrast and brightness fluorescent screen of a color picture tube has a light absorbing layer in the form of fine dots or stripes provided for the inner surface of a panel of the tube on which the phosphor layer is formed, and a light reflection layer provided at an interface between the light absorbing layer and the phosphor layer. To manufacture the fluorescent screen, a photosensitive resin layer coated on an inner surface of the panel is exposed to light through a photomask mounted on outside of the panel to form a pattern. Nonluminous light absorbing substance is applied on the pattern to form the light absorbing layers.

Light exposure apparatus comprises a light source, a spectral filter perivious to light of a prescribed wavelength range, a glass member whose cut-off frequency in the prescribed wavelength range is variable with temperature, and a temperature control for controlling the temperature of the glass member. Intensity of the light from the light source, passing through the spectral filter and glass member, and impinging upon the surface subject to light-exposure is controlled by the temperature control.

In a method of forming a fluorescent screen on the inner surface of a face plate of a color picture tube wherein a film of photosensitive composition consisting essentially of a diazonium salt, the portions of the films to be deposited with phosphors are exposed to light through a color selection electrode so as to impart sticky property to the portions by a photoreaction and moisture in atmosphere and then a powder of phosphors is deposited by utilizing the sticky property, a photosensitive binder is incorporated into photosensitive film which undergoes a cross-linkage reaction with the photosensitive composition, thus rendering the mixture insoluble in water.
