To provide a method for producing a polyoxamide resin by one-step polymerization without performing a pre-polycondensation step in a solvent, which is necessary in the conventional production of a polyoxamide resin. A device for use in drilling subterranean formations includes a first structure secured to a second structure with a bonding material. The invention further provides methods for detecting the GIP90130 polypeptides or nucleic acid sequences, methods for inhibiting interactions between GPBP and GIP90130 polypeptides, between pol k76 and GIP90130 polypeptides or aggregation of GIP90130 polypeptides, and methods for treating patients with autoimmune disorders or cancer. Each of the view finders has an external digital video input unit, which receives input of the digital video signal, and a tally display control unit, which controls tally display based on the tally signal superimposed on the digital video signal. The method and apparatus allow for many variants, all derived from the same general scheme, and which allow different levels of protection against faults. The lens includes a geometrical optics portion for converging light having been incident thereon from its light incoming plane, and two diffraction optics portions provided on the light incoming plane and a light outgoing plane of the geometrical optics portion, wherein the diffraction optics portions are made from a material different from that of the geometrical optics portion.
