MFP matches low-resolution binary image data received by facsimile with a dot pattern showing a jaggy. A permanent current switch is provided and the left and right solenoid superconducting magnets are arranged symmetrically with respect to a center face of the center space. A first on-off valve is inserted in the first line. The superconducting cryostat apparatuses provided by the invention can be configured, in some embodiments, to eliminate the need for sources of external cooling during operation. The loop further includes means for returning the spent to a rehabilitation facility of the spent to form fresh wherein a product is contained in a carrier.
