摘要:
In a lens barrel, a flare diaphragm is disposed on an optical path of lenses or in the vicinity thereof such that the flare diaphragm can advance into and retreat from the optical path for cutting deleterious light corresponding to the lenses moving in the direction of the optical axis. This lens barrel can reliably cut deleterious light flux in a simple structure.

A system promoting a proper recycle of discarded article and contributing economization of energy consumption which will otherwise increase, reduction in the amount of wastes and prevention of environmental pollution due to harmful substances. A recycle system includes an input unit for inputting information concerning article, a storage for storing databases of information for reuse of the articles, a recycle processing method deciding processor for deciding a recycle processing for the article in accordance with recycling rules determined previously by referencing the information for the reuse of the article as contained in the database stored in the storage unit on the basis of the information concerning the article inputted through the input unit, and a recycle factory equipment control unit functioning as an output unit for outputting the result of the decision to a succeeding process.

A strobe camera with a strobe emission section movable between a first position in which strobe light can be emitted and a second position different from the first position. A strobe state detection unit outputs a first strobe state signal when the strobe emission section is in the first position, and a second strobe state signal when the strobe emission section is in the second position. A camera state detection unit outputs a first camera state signal when the camera is in a photographing-permitted state, and a second camera state signal when the camera is in a photographing-prohibited position. A control unit causes the camera to execute a warning operation when the camera state detection unit outputs the first camera state signal and the strobe state detection unit outputs the second strobe state signal, and causes the camera to stop execution of the warning operation and perform an exposure operation when the first strobe state signal is output instead of the second strobe stage signal.

A photographing apparatus is equipped with a photographing optical system, a film holding member on which the photographing optical system is fixed, a supporting frame which rotatably supports the film holding member around a shaft, an outer supporting frame which rotatably supports the supporting frame around the shaft, a finder optical system which has an optical axis different from that of the photographing optical system and which is mounted on the top surface of the outer supporting frame, an AF distance measuring section for measuring the distance to an object, and a captive cam for driving the film holding member and a captive cam for driving the supporting frames for correcting parallax in accordance with the output of the AF distance measuring section. The captive cams are driven also for correcting the blur of an exposure image.

A matrix relay is formed with a plurality of latching relays arranged in a matrix and mounted on a base of an electrically insulative material. Each of the latching relays comprises an excitation coil, permanent magnet, a pair of first and second fixed contacts, and an armature carrying a pair of first and second movable springs each providing movable contacts. The armature is magnetically coupled to the excitation coil so as to be movable in response to energization of the coil by current of selective polarity between close and open positions of the fixed and movable contacts. A plurality of the armatures of the latching relays arranged in a row of the matrix are assembled into a single armature block to be mounted on the base as a single unit. The armature block comprises a single pair of first and second supporting members made of an electrically conductive material. All of the first movable springs and all of the second movable springs of the latching relays of the armature block are connected respectively to the first and second supporting members mechanically and electrically, so that two row paths for electrical signals common to the latching relays arranged in the row of the matrix are provided. This simplification of the structure and electric circuit of the matrix relay would be useful to small-size the matrix relay without complicated fabrication process.

First, a metal layer is deposited on a silicon film surface to form a silicide layer in an interface between the silicon film and the metal layer. Subsequently, the metal layer is all removed by etching such that silicide islands are left on the surface of the silicon film, and then the exposed silicon film surface is dry-etched by using the silicide islands as a selective mask.
摘要:
A camera capable of changing over the photographing frame size thereof having a photographing frame size changing member disposed in a camera body and capable of moving between a first position at which the photographing frame size changing member partially covers a film exposing opening and a second position at which the changing member does not cover the film exposing opening; and an operation member disposed on a rear cover of the camera for selectively bringing the photographing frame size changing member to the first position or the second position, wherein the changing member and the operation member are non-mechanically connected to each other in a state where the film is interposed between the changing member and the operation member. In another embodiment flexible changing members, being positively driven, are guided from a position behind the film to a position in front of the film exposing opening. Visual and/or audible indicators are provided to alert an operator as to the photographing frame size.

A device determines an aperture value Av and a time value Tv for controlling exposure, on the basis of the detected focal length, the detected image magnification and brightness of an object. First, a type of photography is determined according to the focal length (f) and a image magnification .beta., on the basis of fuzzy logic. Then, a combination of an aperture value Av and a time value Tv which are proper for the so-determined type of photography is automatically determined. The combination can be changed by a manual operation. If the combination is changed, a display showing a depth of field corresponding to the changed aperture value Av is indicated.
摘要:
A fluid-filled elastic mount including a first and a second support member, an elastic body for elastically connecting the two support members, and a closure member fixed to the second support member to form a fluid chamber therein. The closure member includes a flexible diaphragm and a metallic member secured to the outer periphery of the diaphragm. The metallic member is press-fitted in a large-diameter portion of the second support member remote from the first support member, and fixed by caulking to the large-diameter portion. At least one sealing rubber lip is pressed between the metallic member and the second support member to assure the fluid tightness of the fluid chamber. Further, a fluid discharge passage is formed radially outwardly of the sealing rubber lip(s), between the metallic member and the large-diameter portion of the second support member, for permitting the fluid to be discharged from the fluid chamber. Also disclosed is a method of producing such a fluid-filled elastic mount.
