    摘要： A rear projection type display system with a transmissive screen. A transparent reinforcing plate is coupled to a lenticular sheet of the screen on the light output side by a connective member to broaden the horizontal diverging angle by 60 degrees or more to the right and left sides. The duty factor of a black stripe formed on the lenticular sheet is set to 60% or more so improve the contrast of an image. The diverging angle at each point of a vertically-diffusing lens for diverging light in the vertical direction is modulated in accordance with the height of each point to offer a proper visual angle range in the vertical direction.

    摘要： A process for manufacturing an alkenyl compound which comprises reacting an alkylbenzene and 1,3-butadiene in the presence of metallic sodium or a combination of metallic sodium and an oxide, a hydroxide, or a salt of potassium, rubidium or an alkaline earth metal, or a mixture of these under a pressure of 1 kPa (gauge) to 30 MPa (gauge). The process can produce alkenyl compound which is an industrially valuable compound as a raw material for the manufacture of naphthalenedicarboxylic acid, a highly useful raw material of polymers, at a high yield using a small amount of metallic sodium.

    摘要： The present invention provides a spray-drying granulation apparatus having a chamber comprising (a) an upper section which is a spray-drying section for spraying a feed solution from a nozzle and drying the formed droplets with hot air and (b) a lower section which is a fluidized granulation section, in which apparatus there is used, as the nozzle for spraying a feed solution, a two-fluid pressure nozzle comprising a centrifugal pressure nozzle for spraying a feed solution and a cylindrical pipe for blowing out a high-speed gas, provided around the centrifugal pressure nozzle. This spray-drying granulation apparatus enables spraying of even a feed solution of large volume with only one nozzle. Further with the two-fluid pressure nozzle of the apparatus, there is no need of replacement of nozzle parts when the feed rate, concentration, viscosity, kind, etc. of the feed solution are changed greatly, because the diameters of droplets formed by spraying can be controlled by controlling the speed of the high-speed gas, while in the conventional nozzles the replacement of nozzle parts such as orifice, core and the like has been necessary when the above change is made.
