摘要:
An automatic film developing apparatus for developing a photographic film being guided by a leader, comprising a film separating and forming mechanism for separating the developed film conveyed from the developing section of the apparatus from the leader, and forming the separated portion of the film into a specified shape. The developed film is automatically separated from the leader by the film separating and forming mechanism, and, at the same time, the separated portion is formed in a predetermined shape so as not to be caught in the guide of the negative mask or in a predetermined shape so as to be easily wound up in the cartridge, thereby saving the labor and enhancing the job efficiency.
摘要:
The present invention relates to a chromone derivative of formula (1): ##STR1## (wherein R.sub.1 and R.sub.2 are the same or different and independently represent a hydrogen atom or a lower alkyl group) as well as a synthetic intermediate thereof and an aldose reductase inhibitor comprising said derivative as an active ingredient. The chromone derivatives of the present invention can be easily synthesized, and are useful as aldose reductase inhibitor with an excellent inhibitory action on aldose reductase.
摘要:
Various arrangements are proposed for coupling films to a leader. A hole is formed in one of the films and the leader to receive a tab which is formed on the other. These arrangements allow stable coupling of the films to the leader and easy uncoupling. They eliminate the use of splice tape.
摘要:
There are disclosed a leader for use in developing a film, methods for attaching the leader to the film and for detaching it therefrom, and an apparatus for automatically attaching the leader to the film and detaching it therefrom. The apparatus for automatically attaching the leader to the film includes a leader set cover for holding the leader, a leader guide defining an arcuate path, leader feed means for feeding the leader from the leader set cover to the leader guide, leader backing means for backing the leader to a leader controlling part to curve the leader, and film feed means for feeding the film toward an elongated opening of the leader.
摘要:
A film feeding apparatus feeds films in cartridges secured to leaders into a film developing section, A film insertion box provided adjacent to the film developing section has a film setting chamber and a film feeding chamber. An inlet slit is formed in the film feeding chamber. Mounted in the film feeding chamber are a first carrier device for feeding the leaders inserted into the slit downwards with the cartridges disposed thereunder, a second carrier device (50) for intermittently feeding the leaders toward a deep area of the film feeding chamber, and a third carrier device for feeding the leaders up into the film setting chamber. In the chamber are provided leader guides for guiding the leaders toward the film developing section, and an infeed device for feeding the leaders into the film developing section.

摘要:
A film-rewinding apparatus to rewind a film from a cartridge into a container which can accommodate the film therein by inserting the film from an opening of the container. The apparatus comprises a cartridge-supporting portion which supports the cartridge; a shielding door driving mechanism for opening and closing the shielding door; a spool-driving mechanism for feeding the film out by driving the spool; a container-supporting portion for supporting the container; an opening and closing driving mechanism for opening and closing the opening; and a film-dismounting mechanism for dismounting the film from the spool. The film-rewinding apparatus can easily perform rewinding by only operating a handle or lever, or by a switching operation, after the cartridge and the intermediate magazine are set and the cover is locked.
