IPC: G03C5/26
Filed: 1983-07-14
Abstract: PURPOSE:To control a change in the performance of a developing soln. with the lapse of time by filling an alkali processing soln. contg. a 3-pyrazolidinone developer into a breakable container, incorporating the container into a photographic element so that the soln. is released into the photographic layer, and subjecting the processing soln. to specified heat treatment before use. CONSTITUTION:A 3-pyrazolidinone developer is added to an alkali processing soln. which is used in the presence of a silver halide developing agent after exposure. The processing soln. is filled into a container breakable under pressure, and the container is incorporated into a photographic element at a position suitable for the diffusion of the processing soln. released from the container by breaking in the photographic layer. At the position, the container does not hinder the exposure of the silver halide emulsion layer. The processing soln. is heat treated before use in the absence of oxygen for >=T days represented by the equation (where X is the maximum heating temp. of >=about 40 deg.C). The performance of the processing soln. changes gradually in the absence of oxygen for several years, yet finally the change stops perfectly. The change depends largely on temp., and the change is accelerated at a high temp., yet finally it also stops. Accordingly, a favorable characteristic curve with no change in gradation is obtd. by using the processing soln. after heat treatment for a fixed period.

Abstract: PURPOSE:To easily and certainly peel and separate a sheet wound on a drum with high reliability by providing a suction/separation means which sucks a sheet by suction when it is pressed into contact with the sheet, and separates the sheet from the drum when it is separated from the drum. CONSTITUTION:In the state where a suction/separation means 17 is pressed into contact with the carrying directional top end p-d side of a sheet P wound on a drum 12 to attract the sheet P by suction, the means 17 is separated from the drum 12, and thereby the sheet P is separated from the drum 12.

Filed: 1991-03-15
Abstract: PURPOSE: To effectively reject all splice-containing tubes by rejecting a tube disposed at a second place at the time of a measured length of a strip being equal to a strip length decided between first and the second places. CONSTITUTION: When a count by a counter arrives at a predetermined value corresponding to a time required for a splice to move from a splice detector 20 to a rejecting chute 82 at a present operating speed of the machine, each counter generates an output signal. Pulses counted by the counter are guided out from a meter wheel regulated at a speed of a strip entering the machine, and the apparatus is automatically regulated to a machine operating speed. A valve controller operates an allowance/rejection valve to deflect a tube adjacent to the chute 82 to the chute 82 to prevent it from arriving at an allowance tube 84. Thus, the tube including the seam from an input strip can be rejected.
