Abstract: PURPOSE:To provide the composite with high strength and high elasticity by mixing Y2O3 stabilized ZrO2 short fibers in a molten metal of an Al base alloy, injecting the above into a die while pressure is applied, executing secondary pressurizing and controlling the reaction rate. CONSTITUTION:Y2O3 stabilized ZrO2 short fibers subjected to interface soln. treatment are previously mixed in a molten metal of an Al base alloy contg., by weight, 0.1 to 6% Mn, 0.2 to 4% Cr, 0.2 to 4% Si, 0 to 2% Ni and 0 to 2% V. They are injected into a die while pressure is applied and are integrally compounded. Furthermore, secondary pressurizing is executed to form acicular intermetallic compounds, which are uniformly dispersed and allowed to coexistent into an Al solid soln. matrix. Moreover, under pressure casting, an Al matrix peritectic alloy is brought into reaction with the intermetallic compounds to execute the compounding of the peritectic matrix alloy intermetallic compounds/the Y2O3 stabilized ZrO2 short fibers. In this way, the composite can be manufactured by a die casting method.

Title: Preparation of toner for development of electrostatic charge image
Inventor: NAGATSUKA TAKAYUKI
IPC: G03G9/08
Filed: 1988-12-22
Abstract: PURPOSE:To obtain a toner for developing electrostatic image which provides picture images having high picture quality by disintegrating previously coagulated additive agent as pretreatment before mixing color particles with the additive agent. CONSTITUTION:After disintegrating a previously coagulated additive agent, the additive agent is mixed with a toner and dispersed on the surface of the toner. Satisfactory effect is obtd. only when the additive agent is fine silica powder. The fine silica powder has strong coagulability and remains easily in the form on coagulated product. But, the amt. of the coagulated body of silica is reduced remarkably by this pretreatment, so clogging of a sieve is prevented by this method, and filtration of a mixture of the mixture of the fine silica powder with the toner is attained with high filtrability and improved productivity. Moreover, since almost all of the added fine silica powder sticks effectively to the surface of the toner particles, fluctuation of the amt. of silica to be added is held at a low level. Thus, a toner for developing electrostatic images capable of providing satisfactory picture images is obtd.
