摘要: A zoom lens mechanism foldable and retractable to be used in a digital still camera to control zooming of the zoom lens uses programmed data written in a micro controller unit (hereinafter referred to as MCU) instead of the conventional cylindrical grooved cams that are usually used to mechanically control zooming of a zoom lens of a digital still camera, and the assembly of the second lens group is rotatable inside the lens barrel, and the first lens group can be folded and retracted into the space provided by the rotation of the second lens assembly.

摘要: A plasmid vector characterized by comprising a promoter sequence that can be recognized by an RNA polymerase which is not inherent in a host and that controls the expression of desired genes and a replication origin that increases the number of copies under the induction by exogenous factors; methods for expression and isolation of target genes by using the vector; a polypeptide having the activity of an AccIII restriction endonuclease; and a DNA encoding the polypeptide. The invention provides for the first time a plasmid vector which can introduce an exogenous desired gene encoding proteins which are lethal or harmful to hosts into the hosts, a method for efficiently expressing the proteins by using the vector, and also a method for permitting a restriction endonuclease gene constituting a restriction-modification system to be isolated even in the absence of a modification enzyme gene, which has been difficult in the prior arts.
