An ambulatory or stationary device for delivery of a therapeutic amount of nitric oxide to an individual’s lungs. The virtual reality networked computer system has an infrastructure that includes a number of users, hosts and servers. The launch clock signal and the capture clock signal are generated based on a plurality of clock signals having different phases, and a pulse width of the plurality of clock signals is smaller than half of a cycle of the plurality of clock signals. Further, the second material layer exhibits resistivity which is lower than resistivity of the first material layer and higher than resistivity of silicon or semiconductor layers which constitute channels of the switching elements. A flat relief portion is formed between the radially tapered portion and the shielding portion.
