    摘要： A diagnostic system in which the accuracy of the diagnosis of the deterioration state of a catalyst (40 in Fig. 1) in a catalytic converter (4) for cleaning the exhaust gas of an internal combustion engine (2) is enhanced without incurring a rise in cost. The temperature of the catalyst (40) is estimated using the operating-state signal (for example, the flow rate of intake air Q a or the width 120 of a fuel injection pulse) of the engine (2) by a diagnostic device (8). The conversion efficiency of the catalyst (40) calculated from the outputs of oxygen sensors (6a, 6b) is corrected using the estimated temperature by the diagnostic device (8). The deterioration state of the catalyst (40) is diagnosed on the basis of the corrected temperature by the diagnostic device (8).

    摘要： A photosensitive composition used in forming patterns for colour picture tubes comprises (a) a copolymer of acrylamide and diacetoneacrylamide and (b) a water soluble aromatic bisazide compound. This composition is improved by incorporating a sulfonated vinyl monomer such as sodium-p-styrene-sulfonate in the copolymer. This composition has the advantage that it follows a reciprocal failure law; i.e. the degree of cross linkage of B is related to the intensity i and exposure time t of irradiation by the equation B =f(i.t.P) where p is Schwarzschild's constant, which is in the range 0

    摘要： In a method of forming a fluorescent screen of a color picture tube by a dry process, the method comprises a first step of precoating an emulsion containing a powder of acryl resin on an inner surface of a face plate of the color picture tube, a second step of coating on the primary coating a photosensitive composition consisting essentially of a diazonium salt to form a thin film, a third step of exposing to light a selected portion ofthe thin film to render the same to become adhesive, a fourth step of depositing a powder of a phosphor to form a phosphor layer of a first color and a fifth step of repeating the third and fourth steps to form phosphor layers of second and third colors. This method can prevent fogs caused by adhering phosphors of other colors to peripheries of previously deposited phosphor previously coated.
