After materials to be cooked have been put into the container main body 12, the container cover plate 10 is aligned monolithically with the container main body 12 by rotation fasteners 13. When the motor 5 is rotated, a speed reducing mechanism 8 allows stirring to be reduced to an optimum revolution, and also allows torque to be developed so as to let the stirring vanes 14 be rotated so that the materials to be cooked are stirred. This constitution can prevent highly viscous materials to be cooked such as curry, stew and the like from being locally boiled and burning, and can also distribute temperature uniformly. Furthermore, this prevent a cook from being burnt because of spray of cooking oil.

IPC: G03G9/107
Filed: 1987-03-26
Abstract: PURPOSE:To obtain a lightweight carrier for a developer not requiring high torque of a developing machine and having controlled unevenness of magnetic characteristics by forming layers of an iron oxide-base magnetic body on the surfaces of core particles by plating. CONSTITUTION:Layers of an iron oxide-base magnetic body are formed on the surface of core particles by plating to obtain a magnetic carrier for a developer having 20-80emu/g saturation magnetization (sigmae). Arbitrary particles having <=4.0 specific gravity after plating the magnetic body can be used as the core particles. For example, the core particles are resin particles contg. a rubberlike elastic body or hollow inorg. particles such as glass, silica or SHIRASU (volcanic glass) balloons. The layers formed by plating are regulated so that the carrier has 20-80emu/g, preferably 30-65emu/g saturation magnetization. Since the resulting carrier is light in weight and the density of a toner can be increased when the particle size of the carrier is made smaller, high quality stable images are obtd. over a long period.
