IPC: G21C15/02
Filed: 1990-03-08
Abstract: PURPOSE:To mitigate thermal stresses of members and to keep structural integrity by elimianating a baffle plate which is, used to be, essentially required, and by forming, in stead, a gas space at least at an upper surrounding wall part. CONSTITUTION:At an upper half part 5A of a housing vessel of high temperature coolant, a plate 24 forming a gas space is placed, and its upper and lower ends are fit to an outer circumference part of the upper half part 5A to form a ring shaped gas space 25 internally. This space 25 is connected to a cover gas atmosphere which is sealed into an upper end part of a reactor vessel 1 through a gas vent hole 26 on a top part of the space. Under this constitution, temperature of a region G is around 380 deg.C and of a region E is around 530 deg.C during normal operation. Accordingly, by setting appropriately width of a region F which is the space 25, and by making the region function as a thermal insulating material, temperature of the region F can be set to be around 450 to 480 deg.C. Consequently, temperature difference to thickness direction of the plate 24 forming the gas space, becomes some 70 to 100 deg.C and the temperature difference can be reduced and also its structure can be simplified by elimination of a baffle plate.

Filed: 1989-03-10
Abstract: PURPOSE:To prevent thermal fogging by incorporating a part contg. polyvalent metal ions at a specific ratio or above into a photosensitive silver halide at >=10% weight of the silver halide. CONSTITUTION:The Frenkel balance in silver halide particles collapses and the concn. of interlattice silver ions lower when a large amt. of the polyvalent metal ions are doped. On the other hand, the silver ion vacancy concn. having the equil. relation with the interlattice silver ions increases. The salt of the polyvalent metal ions is required to be made present during the particle formation of the silver halide in order to dope a large amt. of the polyvalent metal ions. The part where the silver ion vacancy governs, namely, the part where the polyvalent metal ions are doped at >=1X10<-4>mol/molAg is required to be >=10% of the weight of the total silver halide even if any structure is assumed. The heat developable photosensitive material which prevents the thermal fogging is obtd. in this way without hindering the development.
