There is disclosed a silver halide photographic emulsion comprising silver halide grains, wherein 50% or more of the projected area of the silver halide grains to be contained is occupied by tabular grains having an aspect ratio of 2 or more and a grain thickness of 0.2 &mgr;m or less, with the tabular grains each having a phase with the content of silver bromide being 10% or more, and wherein in the phase, the tabular grains each contain a metal complex dopant in an amount necessary to increase the density of a dislocation. This emulsion produces high contrast and better granularity while it has high sensitivity. Further, there is also disclosed a silver halide photographic emulsion, wherein the average equivalent-circle diameter of the total tabular grains among the silver halide grains contained is 2.0 to 4.0 &mgr;m, and the tabular grains contain at least one metal complex having, as a ligand, a heterocyclic compound in a number more than half of the coordination number of the metal atom. This emulsion has high sensitivity and excellent photographic characteristics exhibiting little change of gradation upon exposure to high-intensity illumination. In addition, the present invention provides a silver halide color photographic light-sensitive material using the emulsion, and a color image forming process that is simple and rapid and places little load on the environment, using the material.

摘要:
A heating apparatus for hyperthermia utilizes electromagnetic waves for locally heating cancerous cells within a living body. Electromagnetic waves output from a single electromagnetic wave generating means are branched into a plurality of branched electromagnetic waves, which are respectively employed to conduct hyperthermia treatments for a plurality of patients. The whole of the hyperthermia system is controlled in a concentrated fashion from a single section by means of time-division multiplexing. It is therefore possible for a plurality of patients to be subjected to hyperthermia treatment at the same time and in parallel with each other, even when the conditions of these patients differ from one another. Further, it is advantageously possible to simplify the arrangement of the system as a whole and stabilize the control of the system.
摘要:
A heating apparatus for hyperthermia utilizes electromagnetic waves for locally heating cancerous cells within a living body. When it is necessary for a plurality of patients to be subjected to hyperthermia treatment at the same time and in parallel with each other, the control of a plurality of electromagnetic wave outputs and the control of cooling of the surface of a heated region are effected by a centralized control which employs time-division multiplexing. Thus, it is advantageously possible to efficiently carry out a hyperthermia treatment which is fitting for the condition of each of a plurality of patients.
