摘要:
Disclosed is an artificial tooth that is structured such that the tooth is firmly held in its proper position in a core until a plate resin is fully polymerized and cured in succession to the manufacture of a wax denture. To this end, the artificial tooth has on its portion to be embedded into the core a projection for a temporary bond with the core. Also disclosed is a manufacturing method of an acrylic resin denture comprising the steps of forming a projection for a temporary bond with a core, on the portion of a finished artificial tooth to be -embedded into a core material before the finished artificial tooth is embedded into the core by applying a drop of resin that is of the same type as the material of the artificial tooth, and the step of removing the core along with the projection after a plate resin is polymerized. Instead of the application of a resin drop, a resin pellet can be glued on the portion of the finished artificial tooth to be embedded into a core material before the finished artificial tooth is embedded into the core.

The mold assembly for magnesium alloys comprises a mold and/or a core, each formed of an air permeable material. The air permeable material is any one or any combination of a network, a sheet having multiple holes, and cloth. The network, the sheet or the cloth is any one or any combination of a metal, a chemical fiber, and a ceramic material. The invention also provides a casting method for magnesium alloys, which uses that mold assembly.

摘要:
A developing device in which toner fed from a toner cartridge is caused to flow down by a toner supply roller and, then, mixed with a developer by an agitating roller unit which is made up of a spiral blade and a plurality of radial blades. The spiral blade of the roller unit is greater in outside diameter than the radial blades. Those parts of the spiral blade where the individual chambers are located are notched at one side of the spiral blade and intermittently with respect to an order in the circumferential direction, and those parts of the radial blades where the individual chambers into which the developer from the notched parts of the spiral blade flows are notched. The developing device further comprises a developing roller, a paddle wheel for supplying the developer to the developing roller, a doctor blade for regulating the developer on the developing roller to a predetermined thickness, a separator for returning the developer scraped off by the doctor blade toward the paddle wheel and roller unit, a restricting member extending from a developer outlet side of the separator to a position between the paddle wheel and the developer agitating roller unit for blocking a part of the developer collected from the separator. The developer is moved away from the paddle wheel in response to rotation of the roller unit.
