Patent JP-S58198544-A (JP)
Title: Thermoplastic resin composition
Inventor: MORIMOTO TAKUROU
IPC: C08K7/00
Filed: 1982-05-17
Abstract: PURPOSE:To provide a thermoplastic resin compsn. which can be colored black without lowering physical properties, by incorporating a fibrous reduced alkali titanate in a thermoplastic resin. CONSTITUTION:0.2-50wt% fibrous reduced alkali titanate and, if necessary, carbon black, liquid adhesive and additives are blended with a thermoplastic resin. The fibrous reduced alkali titanate can be obtd., e.g., by heat-treating a mixture consisting of titanium oxide, an alkali carbonate and a compd. which decomposes at 500 deg.C or lower and evaporates or burns. When the content of the fibrous reduced alkali titanate in the resin compsn. is less than 0.2wt%, the resin comspn. can not sufficiently be blacked, while when it exceeds 50wt%, the strength and the appearance of the resin compsn. are deteriorated and workability during mixing becomes poor. A dispersant may be added in order to facilitate the dispersion of the alkali in the resin. Examples of the dispersants are nonionic, anionic, cationic and ampholytic surfactants.

Inventor: IWATA HIROSHI
IPC: B22C3/00
Filed: 1993-03-04
Abstract: PURPOSE:To dispense with the repairing/executing process, to omit the set-up process, and to remarkably improve the dimensional precision by using the plating film having the heat insulating property, the heat resistance and the functionality to the die in the low pressure casting and the die casting. CONSTITUTION:The surface roughness of the die is rough in the range of 30-400mum, the adhering surface of the plating is increased, and the stresses associated with the thermal expansion/contraction are dispersed to prevent the peeling of the film. The eutectoid dispersion of the particles and fibers such as the organic resin and ceramics is realized on the plating film. This allows the relaxation and dispersion of the stresses in the plating film and provides the effect of the peelability. The heat treatment is executed to release the excessive gasified contents in the plating layer and the adhesivity is improved. The eutectoid-dispersed particles and fibers of organic resin are eluted by the heat in the heat treatment to form the porous plating film to keep the heat insulation. The eutectoid-dispersed particles and fibers of ceramics improves the heat resistance and the heat insulation. In addition, the eutectoid dispersion of the high thermal conductive substance in the plating film can manufacture the casting of aluminum of fine equi-axed crystal.

Title: Image density control method of copying machine or the like
Inventor: MASUMURA MASAO
IPC: G03G15/08
Filed: 1989-04-03
Abstract: PURPOSE:To prevent picture quality from deteriorating by switching control corresponding to an image density signal to control over toner supply corresponding to magnetic permeability detecting signal when a detected value of magnetic permeability variation is different from a set prescribed value. CONSTITUTION:When the detected value of magnetic permeability variation varies above or below the set prescribed value, the control over toner supply corresponding to an image density signal detected by an optical sensor 28 is switched to the control over toner supply corresponding to a magnetic permeability detecting signal detected by a developer density sensor 29. Thus, when toner density becomes a certain value larger or smaller than the certain specified value, the control is switched to the toner supply control, so developer density can be controlled into a certain range and defects such as greasing and carrier sticking can be eliminated.
