Provided herein are DNA origami devices useful in the targeted delivery of biologically active entities to specific cell populations. The proximal housing can be provided with a plenum chamber being defined therein, the plenum chamber being in fluid communication with at least one nozzle. One of the removablereplaceable process cartridges may be associated with an exposure device which is only used to expose a portion of that process cartridge while the other removablereplaceable process cartridges may be associated with at least one other exposure device. The third joint is configured to position the mounting post in a selected vertical position relative to the mounting rail and in a selected longitudinal position along the mounting rail. An opening is formed in the interlayer insulating film subjected to the planarization treatment. When an L2 cache control unit that controls an L2 cache in the write-back mode, a bus interface unit, and so on, are normal and snoop processing may be continued, the snoop processing is continued in the processor, in which an error occurred, regardless of whether or not the processor is reset.
