A shutter speed setting member is mechanically connected to an electrical timing circuit and an electrical control circuit wherein the movement of the setting member to either an automatic exposure controlling position or any one of a number of manual exposure setting positions actuates respective change-over switches in the timing control circuitry to adjust the exposure and to provide an indication as to whether the exposure is proper so that the photograph will be unaffected by camera movemen...

A camera outfit for connecting a flash unit to a photographic camera including a connecting device is disclosed. The connecting device according to one embodiment of the present invention comprises a solid strip having one end formed with a groove cooperative with a set screw mounted at the bottom of a flash unit. By fastening the set screw, the flash unit can be mounted on the solid strip which is in turn similarly connected to the camera. Alternatively, this connecting device according to othe...

A driving mechanism for the movable reflector in a single lens reflex camera, wherein, when the movable reflector is rotated from a viewing position to a photographing position, in relation to the optical axis, the rotating torque increases proportionally to the increase of the angle of rotation, and when the movable reflector reaches the photographing position, the shutter release is positively effected. In using this mechanism, the movable reflector can be manually operated, and the image cond...

A self-processing camera of the type employing a replaceable magazine housing a stack of self-processing film units successively advanceable from a focal plane window, includes a lens support swingable between extended and retracted positions and spring biased to its extended and releasably locked in its retracted position. A spring loaded transport mechanism is actuated with the manual retraction of the support to advance a film unit, rupture its processing agent envelope and discharge the film...

A camera having detecting means for detecting a light passed through the objective lens, comprising photocells which receive light rays transmitted through an objective lens and which are disposed in front of a light sensitive member but out of the way of the light path of the focusing image light passed through the objective lens, the first screen (the front screen) of a focal plain shutter which is started to run out when said photocells receive the reflected light from the first screen surfac...

A self-processing camera is adapted to receive and contain a plurality of film units, each including an image recording unit consisting of a light sensitive sheet and a superimposed image receiving sheet, with a rupturable portion containing processing agent provided on one side of image recording unit and a trap for receiving excessive processing agent provided on the other side thereof. After each film unit has been exposed, it is individually transported by a film unit transporting frame, so ...

The liner covering the inner wall surface of the drum of a grinding mill comprises a plurality of rectangular lining units each having an inner working surface inclined to approach the drum centerline from its upstream end to its downstream end, the lining units being in mutual dispositions such that lining units which are mutually adjacent in the drum rotational direction are mutually staggered in the drum longitudinal direction, and each lining unit is provided at its leading side part in the ...

A temporary solidifier for playing with sand or the like together with added water to form a work having a desired shape is disclosed. The temporary solidifier consists of a combination of adequate quantities of a glue and a revolsing enzyme and is added to the sand or the like.

A bearing material which comprises a back metal; a porous sintered layer formed by using a powder of iron, copper, iron alloy or copper alloy on said back metal; and an impregnated layer formed by impregnating a mixture of polytetrafluoroethylene resin powder, zinc powder and aluminum oxide powder to said porous sintered layer, said bearing material having excellent resistance to load, wear and scraping and being suitable for reciprocating sliding mechanisms receiving large and fluctuating loads...

A camera has a cavity for receiving a self-processing film cassette and includes an automatic exposure control circuit and a flash device which are provided with energizing contacts located in the cassette receiving cavity. The film cassette houses a battery connected to contacts mounted on the cassette and engaging the cavity contacts when the cassette is received in the cavity. The exposure circuit responds to a photosensitive element exposed to the objective traversing light reflected by the ...
