Abstract: A method of making a composite structure including at least a plating film disposed on a substrate having at least a surface portion formed from a metallic base material. The method includes the steps of discharging a composite plating solution containing insoluble particles from a nozzle and impacting the composite plating solution on the surface portion of the substrate at a predetermined flow rate. During at least a portion of the discharging and impacting steps, the surface portion of the substrate is abraded with the insoluble particles in the plating solution discharged from the nozzle. A voltage can be applied between the base material and the nozzle, which are electrically connected by the plating solution, to thereby deposit a plating film on the surface portion of the substrate by electroplating.

Abstract: A camera having an autofocus function, independent of a photographing optical system, includes a photographing optical system including synthetic resin lenses and an autofocus optical system, provided independent of the photographing optical system, having at least one synthetic resin lens and a stop decentered in a direction perpendicular to the optical axis of the synthetic resin lens. Thus, in the camera, the shift of the imaging position of the photographing optical system which is caused by an ambient temperature or humidity change is favorably corrected, and good photography can be performed.
