A phase detector device having a modulo N operator coupled with an adder is disclosed. The article can also include an epitaxial superconducting layer deposited on the epitaxial buffer layer. First slits are formed in the pixel electrode, and second slits are formed in the common electrode. The slope of the conical guide ring’s sidewall is sufficient so that the upper tiers are stacked slightly inward and offset over the lower tiers over the entire length of the guide ring, thus gradually reducing the lateral forces exerted on the unsupported upper tiers. Then, the job is processed with one or more of the processors selected from the first group of processors and the second group of processors.
