Abstract: A zoom lens for a camera having a between-the-lens shutter includes a motor for moving the lens along an optical axis in forward and rearward directions. A switch is operable by an operator to control operation of the motor for moving the lens from an initial position on the axis to a final stationary position that establishes the focal length of the lens. Control apparatus is responsive to the setting of the switch for operating the motor such that movement of the lens from its initial position to its final position always ends after the lens travels to its final position in a predetermined direction.

If all of the transferred images, i.e., unfixed images have been fixed, the fixing operation is stopped, and at least one of the fixing rollers is retracted.

Abstract: An Albada finder has a negative objective lens and a positive eyepiece lens. A frame is formed inside the area of the object-side surface of the positive eyepiece lens and a partial reflection area is formed on the eyepiece-side surface of the negative objective lens. The partial reflection area reflects an image of the frame. The frame is formed to enclose a small area of the object-side surface of the eyepiece lens while the partial reflection area is formed to enclose a small area of the eyepiece-side surface of the objective lens. Substantially all of the remaining area of the eyepiece-side surface of the negative objective lens not enclosed by the partial reflection area fully transmits all light incident on the surface.

Abstract: Positive displacement vacuum pump is provided with a pump body, and a piston is positioned in the pump body with the piston being mounted for actuation by alternative linear movement. An elastic element biases the piston in a first direction, and a cam acts on a first end of the piston, with the cam being rotatably movable along an axis that is coaxial with the longitudinal axis of the piston to drive the piston in an alternating linear movement. A transverse bar is positioned between a first end of the piston and the cam, and the transverse bar is rotatably fixed but translationally guided in the direction of alternative linear movement of the piston. Additionally, the cam comprises a double surface to equally bias the transverse bar at two positions along the length of the bar.

Abstract: The well-known Grob cold forming machine for carrying out the Grob method of impact roll-shaping utilizes rolling head carriers that move toward and away from the workpiece wherein each rolling head carrier is provided with rotatably driven rolling heads. Journalled in the rolling heads are impact formers or rollers which, during rotation of the rolling head, within their circle of rotation perform single forming steps on the workpiece which is mounted on a mandrel. In addition, each rolling head carrier carries a freely rotatably journalled pressure roll having an axis parallel to or angled relative to the mandrel axis, the pressure roll being located outside the rotational circle of the impact former. Via the use of pressure rolls, mainly axial shaping is achieved and thereafter, via the use of the impact former, mainly radial shaping is achieved in the same set-up and on the same mandrel.

Abstract: A method and apparatus for sucking a free end of an optical fiber includes a sucking nozzle. The sucking nozzle is positioned downstream of a capstan wheel around which the optical fiber is wound. The opening of the sucking nozzle is positioned within a range of movement of a path line of the free end of the optical fiber. The path line of the end of the optical fiber moves in accordance with the speed of travel of the optical fiber. The sucking nozzle is positioned perpendicular to a plane defined by the path line of movement of the end of the optical fiber and transverse to an axis of the capstan. Thus, the sucking nozzle is positioned to reliably suck a free end of the optical fiber for a broad range of speeds of the optical fiber.

Abstract: A light intensity control circuit for an optical scanning device in which an intensity of a beam emitted by a laser diode, is modulated in accordance with an image signal. The image signal includes information about gradation levels of an image to be formed by the scanning device on a photoconductive surface.

A driving circuit drives the laser diode such that the intensity of the beam is determined in accordance with the image signal and a difference between the first intensity value and the second intensity value.
