Abstract: To provide a photosensitive material exposure apparatus which is easy for soft focusing exposure. A liquid crystal light regulation member 72 capable of holding light transmission and scattering functions reversibly is disposed between a light source 54 and paper 12. Original image light from a negative film 10 is made to pass through the liquid crystal light regulation member 72, so that the paper 12 is exposed to the light which has passed through the liquid crystal light regulation member 72. The relation of haze (%) with the ratio B/A of the distance B between the liquid crystal light regulation member 72 and the paper 12 to the distance A between the negative film 10 and the paper 12 is represented by B/A<0.3-0.0025 H, preferably, B/A<0.3-0.0029 H. The light transmission and scattering functions can be held wholly or partly or for every pixel by controlling current conduction to electrodes, so that the liquid crystal light regulation member 72 can be made to serve as a soft focusing filter.

Abstract: A method for processing a silver halide photographic material is disclosed, comprising a support and a light-sensitive silver halide emulsion layer provided on the frontside of the support, said photographic material being arranged in a processing container containing a processing solution to form a gap or series of continuous gaps adjacent to the surface of the light-sensitive layer between the frontside of the photographic material and the backside of the same photographic material, or between the frontside of the photographic material and a second photographic material, or between the frontside of the photographic material and a light-insensitive member, said gap or continuous series of gaps having a substantially constant gap width, comprising the steps of introducing a processing solution stream into each gap and replacing the processing solution thus introduced in an amount at least equivalent to the capacity of the gaps.

Abstract: Photosensitive material is processed by charging a plurality of serially arranged compartments defined in the interior chamber of a single processing tank with processing solution, and successively passing the photosensitive material through the compartments while maintaining continuous contact with the solution. The solution can be a developer, bleach-fix solution or wash water. An apparatus is also provided comprising a single tank, a plurality of compartments defined in the tank, and feed rollers in the compartments for feeding the photosensitive material through the compartments.

Abstract: A photosensitive material-drying apparatus for drying a photosensitive material after being dipped in a treatment solution to wet the same. Water-absorbing rollers for contact with the same surface of the photosensitive material are provided in the vicinity of a photosensitive material-introducing inlet, and are arranged along a direction of transfer of the photosensitive material. The water-absorbing abilities of the water-absorbing rollers is increased progressively in the direction of transfer of photosensitive material.

Abstract: A processing tank is partitioned into a plurality of compartments which are serially connected to define a continuous processing path having an entrance and an exit for photosensitive material. The path is filled with a processing solution having a desilvering function such that the processing solution in at least one compartment has a different composition from the processing solution in at least one of the remaining compartments. Silver halide photosensitive material is successively passed through the compartments without contact with the ambient air. Desilvering the photosensitive material after exposure and development in this way reduces the amount of processing solution used, especially replenished, while achieving improved photographic properties.

Abstract: A space-saving, efficient wash tank is provided in which a plurality of compartments are serially connected through narrow channels to provide a continuous processing path, and wash water is supplied to the path through a selected compartment, whereby a strip of photosensitive material is washed with the water during its passage through the path. This wash tank ensures efficient washing and water saving when the selected compartment has a smaller volume than the remaining compartments or when the selected compartment is substantially emptied of the water during a quiescent period, or bath. Wash water flows in counter flow to the travel direction of photosensitive material during operation and is drained from the lowermost compartment at the end of operation.

An outlet for discharging the solution is provided at a location other than the first and last compartments, usually at an intermediate compartment. A plurality of inlets for respectively supplying processing solutions having different functions can be provided at different locations so that the apparatus accomplishes two or more functions in a single tank. The apparatus becomes compact and the amount of processing solution replenished is reduced.

Abstract: A filter apparatus having a filter element and a stop valve, both incorporated in a body thereof. By means of an engagement, the stop valve is coupled with a cap which is fitted to a body of the filter apparatus by thread-engagement. When the cap is removed from the body for replacement of the filter element, the stop valve rotates together with the cap to close an inlet port of the filter apparatus. On the other hand, when the cap is fitted to the filter apparatus, the stop valve directs the fluid into the filter apparatus since an opening provided in the stop valve coincides with the inlet port because of rotation of the stop valve.

Abstract: A feed roller having a hard roller body and a cylindrical resilient cover member fitted onto the hard roller body. The feed roller has internal contact portions formed on an inner surface of the cover member, the internal contact portions being kept in contact with the outer periphery of the roller body when the cover member is fitted onto the roller body; external contact portions formed on an outer surface of the cover member so as to project outwardly in the radial direction of the cover member; and spaces defined between the inner surfaces of the external contact portions and the outer periphery of the roller body. Accordingly, the cover member can easily be attached to the roller body and enables objects to be fed by a small clamping reaction force, thereby preventing the objects from being damaged.

Abstract: In an open joint structure for the prevention of water leakage an isobaric space is formed which has no difference between pressure in the space and ambient pressure. The open joint structure contains at least one groove 11 extending in the vertical direction formed on the exterior side of a vertical edge of a precast concrete curtain wall and which faces an opposing groove 11 of an adjacent precast concrete curtain wall. A heat barrier plate 10 with cutout portions on through holes 13 is mounted between the side walls in the grooves, thereby dividing the isobaric space into a fire-blocking isobaric space (A) between the exterior side of the wall and the heat barrier plate 10 and a radiant heat-blocking isobaric space (B) between the heat barrier plate 10 and a pair of preformed sealants 20, 20. This structure exhibits both a fire-resistant function and a watertight function in an open construction method.

Abstract: An apparatus for heating a processing liquid has a heater for heating the processing liquid and a temperature sensor for detecting the temperature of the liquid. The heater and the sensor are housed in a protective housing made of a metal or a ceramic material. Since the heater and the temperature sensor are provided together in one unit, the mounting of the apparatus on a processing tank is facilitated. In addition, since the output of the temperature sensor changes in accordance with whether the liquid level of the processing liquid is above or below the position to the temperature sensor, it is also possible to detect the liquid level from the change in the output of the temperature sensor.
