Patent number: 6043862Abstract: A wet-type plate-making machine is disclosed in which the amount of a developer in a developing tank and the toner concentration of the developer are maintained constant. In accordance with the detection values of two liquid level detection switches mounted in the developing tank, the developer is supplied from a developer refill pump thereby to maintain a constant amount of developer. The toner concentration of the developer is maintained constant by supplying the toner from a toner refill pump when the detection value of a concentration detection unit of light-transmission type is low, and by supplying the developer from a developer refill pump when the detection value of the concentration detection unit is high. In the case where the developer concentration or the toner concentration fails to change in this control operation, an alarm signal is outputted indicating that the developer bottle or the toner bottle, as the case may be, is empty.Type: GrantFiled: July 2, 1998Date of Patent: March 28, 2000Inventors: Yutaka Ishiyama, Kimiya Yamada, Hiroyuki Nagakura, Eisuke Tsuda

Patent number: 5812898Abstract: A system for processing photographic material has a series of processing vessels containing different water-based processing baths. A reference vessel is mounted on one of the processing vessels and serves to compensate for the evaporation of water from the processing vessels. To this end, the reference vessel accommodates a body of water as well as a float switch having an upper contact and a lower contact. The reference vessel and processing vessels are open at the top and a feeding arrangement is provided to admit water into the respective vessels through their open tops. The feeding arrangement includes one or more pumps connected to a control unit which is further connected to the float switch. When evaporation causes the water in the reference vessel to fall to the level of the lower contact of the float switch, the control unit activates the pump or pumps to replace the water lost from each of the vessels by evaporation.Type: GrantFiled: June 7, 1996Date of Patent: September 22, 1998Assignee: Agfa-Gevaert AG-PhototechnikInventors: Gerhard Benker, Wilfried Hehn

Patent number: 5809362Abstract: A photosensitive material processing device having a processing tank in which is stored a processing solution for processing photosensitive materials. The processing tank is formed such that, given that a tank volume is V milliliters and a path length is L centimeters, a value V/L is less than or equal to 25. A circulating path which circulates the processing solution within the processing tank is provided. A cast heater which heats the processing solution in the circulating path to a predetermined temperature is provided on the circulating path. Accordingly, because the processing tank is long and thin, stores a small amount of processing solution, and has a value V/L of less than or equal to 25, the cast heater heats the processing solution to the predetermined temperature in a short time and stably maintains the predetermined temperature. The photosensitive material processing device is advantageous in terms of cost and environmental preservation.Type: GrantFiled: January 30, 1997Date of Patent: September 15, 1998Assignee: Fuji Photo Film Co., Ltd.Inventor: Osami Tsuji
