    摘要: An improved bias circuit of the quarter-wavelength microstrip line type for a high-frequency amplifier is provided which is of divided form, including two, open and short stubs the sum of whose lengths in effect amounts to a quarter wavelength. The characteristic impedance of such microstrip line can be effectively increased by properly selecting the ratio of the stub lengths, thus enabling realization of a wider-band high-frequency amplifier circuit with reduced cost.

    摘要: A process for producing a molybdenum-bismuth-iron-containing metal oxide fluidized bed catalyst which has a controlled particle diameter and has satisfactory activity and physical properties. In a process for producing a fluidized bed catalyst containing molybdenum-bismuth-iron and silica as a carrier component, dried products formed in a spray drying step and having a particle diameter outside a desired range are pulverized, then the pulverized one is mixed into a slurry before spray drying, the resulting mixture is spray-dried, and the spray-dried particles are subjected to a classification operation to obtain particles having a diameter within the desired range, which are then calcined. The catalyst produced according to the present invention is suitable for producing acrylonitrile by ammoxidation of propylene.

    摘要: For the production of acrylonitrile by ammoxidation of propylene, there is provided a process capable of giving a high yield and maintaining such an effect for a long period of time. In producing acrylonitrile by ammoxidation of propylene, a fluidized bed catalyst is used and the reaction is carried out while appropriately adding a molybdenum-containing material, wherein the fluidized bed catalyst contains molybdenum, bismuth, iron, nickel, chromium, potassium, an F component and silica as essential components, and has a number of Mo/Me of from 0.8 to 1, wherein the Mo/Me is a number obtained by dividing the product 20 of a valence number of molybdenum as molybdic acid and an atomic ratio of molybdenum by the sum of respective products of respective valence numbers and atomic ratios of bismuth, iron, nickel, chromium, potassium, the F component element, a G component element and a Y component element.
