Abstract: Device for taking out sample pieces such as mount-attached slide films from a file sheet in which the sample pieces are held and received in an arranged fashion. Conventionally, such sample pieces needed to be taken out independently. A main body is provided with engaging pawls which engage with respective side walls of a plurality of the sample pieces. The plural sample pieces can simultaneously be taken out by moving the main body along the file sheet through a guide. Therefore, operation for taking out the sample pieces from the file sheet can greatly be facilitated.

Abstract: A glass stage for use as an upper stage in an overhead type projector system. The glass stage includes a rectangular frame body having substantially the same dimension as that of a lower stage of a projector, a lower transparent plate fixed to the rectangular frame body, and an upper transparent plate which pushes a strip film onto the lower transparent plate. The upper plate is rotatably supported by brackets provided on the frame body. Each of the brackets is provided with a longitudinal hole which engages with hinge pins for guiding movement of the upper transparent plate in a drawing direction thereof. The longitudinal hole is provided with a portion inclined downwardly at an end of a pushing side of the upper transparent plate. The rectangular frame body is provided at one side portion thereof with small holes through which the upper stage-fitting pins are to be snugly fitted.

Abstract: An apparatus for simultaneously inserting a plurality of slides into a file sheet and a method for using such apparatus is disclosed. The apparatus comprises a series of pockets which align with a series of compartments in a slide structure. Pawl members in the compartments engage with the slides to retain the slides in the pockets. The slide structure moves reciprocally longitudinally, as well as vertically in the plane of the mounting plate.

Abstract: A microscope including a base frame, a stage provided on or over the base frame, and a file page placed on the stage and adapted for supporting a plurality of samples. An arm extends from the base frame up to a place over the stage. A magnifying optical system has an optical axis directed in a direction orthogonal to the stage, and an illuminating optical system is provided on the axis of the magnifying optical system at a place spaced from the stage.

Abstract: The present invention includes an apparatus for displaying a model of a flying object in a flying condition. By the propulsion of powerless models of flying objects through a circular path under an external power source, the aerodynamic characteristics of the model of the flying object cause the model to be lifted into a flying condition. The apparatus is useful for observing the flight stability of a model of a flying object and as a promotional display for models of flying objects. A driving device is used to rotate the model through a flight path. A transparent hanging line connects the model to the propulsion device.

Abstract: A desktop film viewer includes a box-shaped structure consisting of a cover member and a main member fitted with each other, a light transmission diffusion plate provided on the cover member, and a light source and reflectors provided in the main member to illuminate the light transmission diffusion plate. The box-shaped structure comprises wedge-shaped side surfaces. At the acute angle edges of the wedge-shaped side surfaces, the main member and the cover member are pivotally connected to each other. The box-shaped structure further comprises foldable linked stays for maintaining the box-shaped structure opened at any angles.

Abstract: An information recording carrier-holding sheet in which laterally and vertically extending partition walls are formed in a single rigid resin sheet to form a plurality of rectangular depressions for allowing information recording carriers to be housed therein. Planar lugs are formed on the opposite side walls of each of the rectangular depression while projecting from almost the central portions of the opposite side walls in the longitudinal direction thereof to the inside of the rectangular depression. Guide members for guiding the movement of the information recording carrier in the rectangular depression are provided at the planar lugs in each of the rectangular depressions or in the vicinity thereof.

Abstract: An information recording carrier-holding frame comprising a substantially perpendicular depression peripheral wall defining a depression with a bottom wall; planar lugs provided at at least two opposed side portions of the depression peripheral wall and projecting to the inside of the rectangular depression; and a support provided in and rising from the bottom wall and spaced from the depression peripheral wall portion opposed to the depression peripheral wall portion which is located on the insertion side of the information recording carrier and has no planar lug. An information recording carrier-holding sheet is also disclosed which comprises a plurality of such information recording carrier-holding frame laterally and vertical arrayed thereon.

Abstract: Disclosed herein is a film jacket for strip film comprising a surface sheet, a back sheet and a pair of locating means each consisting of at least two welded portions as a unit which are separated from each other in the width direction of the strip film at distance slightly larger than the width of the strip film, said pair of the locating means being separated from each other in the length direction of the strip film pocket and said welded portions constituting a film pocket for holding a strip film therein. The welded portions of the paired locating means on either one of the upper and lower sides of the film pocket may be united together to form a short or long welded portion which is positioned between the welded portions on the other side of the film pocket.
