摘要： PURPOSE:To provide excellent mechanical strength to a titled element and to prevent trouble such as exfoliation by forming a 1st diffused layer between a 1st layer and intermediate layer and a 2nd diffused layer between a 2nd layer and the intermediate layer. CONSTITUTION:The 1st layer 11 and 2nd layer 15 which are diagonally vapor deposited films are joined respectively via the 1st diffused layer 12 and the 2nd diffused layer 14 to the intermediate layer 13. Since the intermediate layer 13 is an isotropic transparent material, it exerts a less adverse influence on incident light and the effect of phase control is attained by the 1st layer 11 and the 2nd layer 15. Namely, the wavelength at which the light is circularly polarized is defined by the material quality of the 1st material and the 2nd material, the film thicknesses of the 1st layer 11 and the 2nd layer 15 and the angles at which the respective layers are deposited by evaporation. The intermediate layer 13 has the excellent mechanical strength and is securely joined to the 1st layer 11 and the 2nd layer 15 via the diffused layers 12, 14. The inter-layer exfoliation is thereby prevented and the element having the mechanical strength excellent as a whole is obtd.

摘要： PURPOSE: To further efficiently purify NOx in oxygen excessive exhaust gas. CONSTITUTION: A catalyst prepared by supporting a catalytic noble metal on Y-type zeolite or mordenite is arranged in a passage of oxygen excessive exhaust gas and exhaust gas is brought into contact with the catalyst while paraffinic HC is added to the exhaust gas to reduce and purify NOx contained in the exhaust gas. Since the pore size of Y-type zeolite or mordenite is relatively large as compared with that of other zeolite, Y-type zeolite or mordenite is considered to be excellent in the adsorbability of paraffinic HC having a high mol.wt. and shows high NOx purifying capacity.

摘要： PURPOSE:To form double-layer diagonally vapor-deposited films having a double refracting function and liquid crystal orienting function by projecting a material for vapor deposition to a substrate from a diagonal direction, then moving the substrate and projecting the same material for vapor deposition further from a specific angle, thereby depositing the films by evaporation. CONSTITUTION:The material for vapor deposition from a vapor source 3 is projected to the substrate 1 from the diagonal direction to form the 1st diagonally vapor-deposited film on the substrate 1 surface in a vacuum vessel 5 of a vapor deposition device. Ta2O5, WO3, Mo2O3, Bi2O3, Nb2O3, ZnS, etc., are used for the above-mentioned material for vapor deposition. The substrate 1 and the vapor source 3 are then relatively moved so that the angle projected to the substrate 1 is set in a 45+ or -5 deg. vapor deposition direction with respect to the vapor deposition direction of the 1st diagonally vapor deposited film mentioned above. The same material as the above-mentioned material for vapor deposition is projected and deposited by evaporation on the substrate in this position to integrally form the 2nd diagonally vapor- deposited film on the 1st diagonally vapor-deposited film, by which the double-layer diagonally vapor-deposited films useful for a liquid crystal display element are obtd. The incident angle thetafor the vapor deposition of the above-mentioned material for vapor deposition is preferably 45-75 deg..

摘要： PURPOSE: To provide a selective reduction-type NOx catalyst using light oil as a reducing agent and capable of efficiently purifying NOx at 200-400 deg.C. CONSTITUTION: The NOx in an oxygen-excess exhaust gas are reduced and purified by this exhaust gas purifying catalyst, and the catalyst consists of a mordenite-structure zeolite carrier and a transition metal element and noble metal deposited on the carrier. This carrier has elliptic pores, the main pores are unidirectionally extended parallel, and the carrier has an appropriate acid point. Such hydrocarbons as light oil are easily adsorbed in the pore, the noble metal is dispersed and deposited on the acid point, and the catalysis of the noble metal is enhanced. The deterioration of the carrier is suppressed by the transition metal element, the activation of the noble metal with oxygen is controlled, and the overburning of the light oil as the reducing agent is suppressed. Consequently, the temp. to start purifying NOx is kept low, and the temp. range of the inlet gas with the NOx reduced and purified is widened.

摘要： PURPOSE: To efficiently remove NOX in exhaust gas contg. excess oxygen from a diesel engine, etc., over a wide temp. range by using a catalyst consisting of a mordenite type zeolite carrier and Y, etc., and a noble metal carried on the carrier in combination with a reducing agent made of hydrocarbon. CONSTITUTION: A catalyst consisting of a mordenite type zeolite carrier and at least one of Y and La and a noble metal such as Pt carried on the carrier is used in combination with a reducing agent made of hydrocarbon such as light oil. The hydrocarbon such as light oil is adsorbed on the carrier and activated. Since the dispersibility of the noble metal is improved by a porous structure peculiar to the carrier and a moderate acidity, light oil is activated even at a low temp. and an NOX removal reaction is allowed to proceed. At least one of Y and La suppresses the sintering of Pt at the time when thermal load is applied to the catalyst.

摘要： PURPOSE:To enhance durability and light resistance and to improve visibility by forming UV absorptive layers consisting of a UV absorptive inorg. compd. on the inside surface side of transparent substrates and constituting multilayered optical films for preventing reflection together with transparent electrodes. CONSTITUTION:The UV absorptive layers consisting of the UV absorptive inorg. compd. are formed on the inside surface side of the transparent substrates 1a, 1b to constitute the multilayered optical films for preventing reflection together with the transparent electrodes 3a, 3b. The incident UV rays from the transparent substrates 1a, 1b side are absorbed by the UV absorptive films. The deterioration of a sealing agent of the liquid crystal cell 6 or the liquid crystal itself occurring in UV rays is lessened in this way and the reflection is prevented, by which the visibility is improved.
