  • Publication number: 20180211843
    Abstract: A technique capable of controlling in-plane uniformity of a film formed on a substrate includes a step of forming a film on a substrate by performing a predetermined number of cycles in which a step of supplying a metal-containing gas to the substrate and a step of supplying a reducing gas containing an element that becomes a solid by itself to the substrate are performed in a time-division manner. The reducing gas has a property of changing a deposition rate of the film from an increasing rate to a decreasing rate in accordance with the exposure amount of the reducing gas with respect to the substrate. In the step of supplying the reducing gas, the exposure amount of the reducing gas with respect to the substrate is adjusted in accordance with the property of the reducing gas.

  • Patent number: 10033480
    Abstract: SISO decoding of a reception signal having a scrambled symbol arrangement is realized using a process having reduced complexity. Coordinates are generated for a reference point obtained by scrambling and mapping a symbol number not a symbol reference point position. This reference point simulates transmission-side scrambling and is generated for each symbol number by a first mapping unit. Because the binary expression of a corresponding original signal number is retained, a bit likelihood calculation unit can easily calculate a bit likelihood based on the distance between the reference point and a reception signal. The calculated bit likelihood is then deinterleaved and subjected to SISO error-correcting decoding. The thus obtained bit likelihood is then reinterleaved and used to calculate a symbol probability. Soft symbols are generated through the multiplication of all the calculated symbol probabilities by corresponding reference points output by a second mapping unit similar to the first mapping unit.

    Abstract: In a method for determining upper and lower limit values for a target brightness when image contrast is extended, an upper and lower limit value search processing unit establishes two adjacent areas in accordance with brightness of a grayscale histogram, and, while scanning the positions of those areas, compares the frequency of those areas to a threshold, and if one frequency value is greater than or equal to the threshold value and the other frequency value is lower than the threshold, performs upper and lower limit value search processing wherein a brightness value at the boundary of the two areas is determined as an upper or lower limit value. Thresholds for upper and lower limit value search start position and frequency are established based on the shape of the grayscale histogram of an image to be processed. The shape of the grayscale histogram is identified according to preset classifications.
