Abstract: A zoom camera with a pseudo zooming function for assigning a frame a pseudo zoom ratio by which a printing area and a print magnification of the frame are modified to obtain a photo print that looks like being photographed at a virtual focal length that is equal to a multiplication product of the pseudo zoom ratio and an actual focal length of a taking lens used for photographing the frame. A virtual focal length is determined in accordance with operating direction and amount of a manual zooming operation member. A viewfinder is controlled in correspondence with the virtual focal length, to show a photographic field to be contained in a photo print as photographed at the virtual focal length.

Abstract: A camera system for taking i.d. (identification) pictures includes a camera body having a pair of taking lenses, to which one of a plurality of film holders of different film formats is removably attachable from the rear side of the camera body, depending on what film format is suitable for the size of photographs to be taken. A deflection unit deflecting the optical axes of the taking lenses, or a conversion lens unit changing the magnification of the taking lenses as well as deflecting the optical axes of the taking lenses is removably attachable to the front of the taking lenses, depending on the size of the photographs to be taken.

Abstract: An apparatus wherein liquid may be continuously fed at a constant small rate includes a liquid reservoir displaceable up and down and provided at a lower portion thereof with a liquid delivery orifice block, a small liquid dropping tank displaceably supported for up and down movement and provided with a liquid dropping chute and an intake nozzle communicating with the orifice block and disposed at a location lower than the location where the liquid dropping chute is attached to the small liquid dropping tank, a photoelectric droplet counting mechanism provided facing a dropping portion of the dropping chute, and a reservoir raising/lowering mechanism and a tank raising/lowering mechanism adapted respectively to either raise or lower the liquid reservoir and dropping tank in accordance with signals from the counting mechanism.

Abstract: Apparatus for performing operations of agitating a material to be treated in a rotary kiln and scraping away substances adhering to the inner wall of the rotary kiln effectively at a high efficiency so as to operate the rotary kiln continuously for a long time and perform the heat treatment in the rotary kiln very smoothly.

Abstract: A heat shrinkable film is laminated on a film having less heat shrinkage which can be a metal coated film with an adhesive composition having a relatively low shear strength. The heat shrinkable laminate film forms creases by heat shrinking it.
