    摘要: Specified image transformation is applied to a first source video signal to generate a main image and symmetric image transformation is applied to a second source video signal same as or different from the first source video signal in accordance with the image transformation applied to the main image and the point, line, or plane specified as a symmetry yardstick to generate a symmetric image point-symmetric, line-symmetric, or plane-symmetric to the main image. Thereby, it is possible to easily obtain a symmetric image symmetric to a main image to which image transformation is applied only by specifying a point, line, or plane serving as a symmetry yardstick.

    摘要: A local oscillator system carries out a frequency switching method, in which local signals with fewer spurious components can be obtained. The local oscillator system is provided with frequency generators for generating signals with different frequencies and frequency dividers connected to the frequency generators. The dividers divide the frequency of the signals to output the frequency-divided signals while operating in an active mode and output undivided signals while the dividers are operating in inactive mode. The dividers are controlled so that one of the dividers is in the active mode and the remaining dividers are in the inactive mode. The output signals from the dividers are combined with each other to form a single output signal and then the single output signal is sent to a filter. The filter selects a component having a desired local frequency from the single output signal. Spurious components caused by unselected frequencies are removed by the filter because they are not divided.

    摘要: The activity of a tellurium-free metal oxide catalyst used for ammoxidation of organic compounds at a temperature of from 300.degree. C. to 600.degree. C. is improved in the presence of (a) elemental tellurium or a tellurium compound which is in contact with said catalyst or in the presence of (a) elemental tellurium or a tellurium compound and (b) a molybdenum compound which are in contact with said catalyst. This activity improvement process can be applied to both the fresh catalysts and the spent catalyst having a deteriorated activity. The above described component (a) is preferably composed of a tellurium containing solid to be used in a state of a dry physical mixture with said catalyst. The above described components (a) and (b) are preferably composed of a tellurium containing solid and a molybdenum containing solid respectively or a tellurium-molybdenum containing solid to be used in a state of a dry physical mixture with said catalyst.The tellurium containing solid, the molybdenum containing solid or the tellurium-molybdenum containing solid may be at least a member selected from the following group:(1) A solid wherein a tellurium component and/or a molybdenum component is supported or unsupported on an inert carrier,(2) A solid wherein a tellurium component and/or a molybdenum component is added to a metal oxide catalyst (fresh or spent) and/or said metal oxide catalyst is enriched with the tellurium component and/or the molybdenum component, and(3) A solid composed of a compound containing at least one element selected from the group consisting of an alkali metal, an alkaline earth metal, La, Ce, V, Nb, Cr, W, Mn, Fe, Co, Ni, Cu, Zn, Cd, B, Al, Ga, Ge, Sn, Pb, P, AS, Sb, Bi, S and Se in addition to tellurium, molybdenum or tellurium and molybdenum, or a mixture of these compounds, supported or unsupported on an inert carrier.The present invention is advantageously applied to ammoxidation in a fluidized bed.
