Title: Silver halide photographic sensitive material having improved fastness of dye image
Inventor: KANEKO YUTAKA
IPC: G03C7/26
Filed: 1986-09-29
Abstract: PURPOSE:To prevent decoloration and discoloration of a magenta color image due to light by using jointly a specific magenta coupler with a magenta tone stabilizer for the titled material. CONSTITUTION:The titled material comprises one or more kind of the magenta coupler shown by formula I and the magenta tone stabilizer shown by formula II, respectively. In the formulas, Z is a nonmetallic atom group necessary for forming a nitrogen contg. heterocyclic ring, X is H or a group capable of releasing by reacting with the oxidant of a developing agent, R is H or a substituent, R<1>-R<3> are each H or alkyl, cycloalkyl or aryl, etc. In case that the total numbers of R<1>-R<3> groups are less than 8, said coupler and stabilizer flow into a processing solution from the photosensitive material. So that, the total of said carbon numbers is necessary to be >=8. Thus, the fastness of the magenta dye image with respect to light, heat and moisture is improved, and the generation of a yellow stain is prevented in the noncolored part of the image.

Title: Oil deterioration preventing device
Inventor: SAITOU TOMOKATSU
IPC: C11B3/00
Filed: 1990-08-31
Abstract: PURPOSE:To reduce the deterioration of oil so as to enable long time use by forming a semiconductor coat on the surface of a base material made by ceramics to make a compact, and holding the compact in a housing in such a manner that the semiconductor coat is in contact with oil. CONSTITUTION:When an oil deterioration preventing device is dipped in frying oil of a high temperature about 180 deg.C, the frying oil flows into the interior of a housing 4 through holes 4a and communicating holes 4b to be in contact with a compact 1. As a semiconductor coat 3 formed on the surface of a ceramic ball 2 comprises an n-type semiconductor using titania as base, the coat absorbs the energy from the frying oil such as the thermal energy, the kinetic energy generated when the compact is moved in the oil by the heat convection to cause microvibration, and so on, whereby electrons are generated in a conduction band. The electrons generated in the interior are diffused to reach the surface immediately to conduct a reduction action. The surface of the semiconductor coat 3 is put in an activation state to conduct a reduction action to the oil, so that the oxidation of the oil can be restrained and reduced.
