摘要:
A thermodevelopable light-sensitive material having a reduced frequency to fog formation by heat, comprising a support and at least one layer containing (a) an organic silver salt, (b) a catalytic amount of a light-sensitive silver halide or a compound capable of forming a light-sensitive silver halide by reaction with the organic silver salt (a), (c) a reducing agent (d) a binder, and (e) an N-haloacetamide. In order to increase the transparency of the thermodevelopable photographic layer of the material and the density of the image and to improve its preservability, a topcoating of polymer can be formed on the light-sensitive layer.

A gas sensor unit including a gas sensor and a sensor cap, The gas sensor includes a gas detecting element, an electrode provided on the gas detecting element and a sensor terminal connecting to the electrode for transmitting an output signal from the gas detecting element. The sensor cap is adapted for transmitting the output signal to an external device. The sensor cap includes a cap terminal electrically connecting to the sensor terminal and an enclosing member bonding to the gas sensor so as to form an internal space in cooperation with the gas sensor. The enclosing member includes a communicating hole through which the internal space is in communication with a space outside the gas sensor unit, and the communicating hole is gas-permeably and watertightly closed by a filter member.

Developer is supplied to a first spray pipe disposed in a developing bath. The inside of the developing bath is provided with a heater. A liquid-flow generating unit comprises a liquid-flow generating head and a branch duct, which is connected to a branch pipe of the first spray pipe via a rubber hose. A part of the developer flowing in the first spray pipe is forwarded to the liquid-flow generating head. By a gap-forming ring, a gap is secured between an outer surface of the heater and an inner surface of the liquid-flow generating head so that the developer uniformly flows along the outer surface of the heater in a longitudinal direction thereof. A heater cover is attached to the liquid-flow generating head. An inner surface of the heater cover inclines in the longitudinal direction of the heater.
