摘要:
A driving mechanism for holding and shifting a part to be driven. The mechanism has at least three carrying elements for carrying the part elastically by exerting force upon the part in directions generally perpendicular to an axis of the part, at least one of the carrying elements being of a actuating type including a frictional actuator, the frictional actuator having a contact face for contacting the part under the pressure, the contact face oscillating at high frequency so as to make the part move in a direction almost rectangular to that of exerting the force upon the part.

A silver halide photographic light-sensitive material comprised of a support base having thereon a silver halide emulsion layer and an antistatic layer. The antistatic layer contains a nonionic surface active agent having two polyoxyethylene chains in a molecule, the agent being represented by the formula (I): ##STR1## wherein R.sub.1 and R.sub.3 each represents a substituted or non-substituted alkyl, aryl, alkoxy, aryloxy, acyl, amido, sulfonamido, carbamoyl or sulfamoyl group, or a halogen atom, R.sub.2 and R.sub.4 each represents a hydrogen atom, a substituted or nonsubstituted alkyl, aryl, alkoxy, aryloxy, acyl, amido, sulfonamido, carbamoyl or sulfamoyl group, or a halogen atom, R.sub.5 and R.sub.6 each represents a hydrogen atom, or a substituted or nonsubstituted alkyl or aryl group, wherein the sum total of carbon atoms in R.sub.5 and R.sub.6 is 2 or more, or R.sub.5 and R.sub.6 may form a ring by linking with each other, and m and n independently each represents an average degree of polymerization of ethylene oxide which is 2 to 40. The antistatic layer provides a photographic material which has excellent antistatic effects without causing undesirable effects on the photographic properties of the material. The antistatic layer does not cause screen contamination and the antistatic effects do not deteriorate with the passage of time. Particularly good results are obtained with silver halide light-sensitive materials utilized with high speed processing at a high temperature especially when the materials are of high sensitivity.
摘要:
A compact optical lens barrel mechanism for relativenonrotational displacement of a series of lens elements forming an optical system is provided. Lens elements can be mounted for selective subdivision into operative lens groups for both focusing and introducing a variable soft focus condition. The barrel mechanism includes a mounting cylinder having appropriate linear alignment elements. A translational cylinder is rotatively journalled within the mounting cylinder. Three lens mounting members can be relatively movable and are designed to each carry a predetermined number of lens elements. The rear lens mounting member can be moved by the translational cylinder to provide a variable amount of spherical aberration to produce a soft focus condition. An exterior focusing ring and a soft focus condition ring can be rotatively mounted relative to the stationary mounting cylinder for linearly moving the respective mounting members.
