Title: Heat-cooking device
Inventor: IKEDA NOBUO
IPC: H05B11/00
Filed: 1986-06-17
Abstract: PURPOSE:To make it possible to divide a cooling air flow into the upper and lower parts of an oven pan and to bake a food crisply while ventilating suitable by providing suction ports and exhaust pots in both upper and lower parts of a heating chamber partitioned by a rack. CONSTITUTION:By setting an oven pan 8 in the oven, the oven is divided into upper and lower parts. Therefore, at the time of a grill heat-cooking using an electric heater, a heating space becomes small, and the ambient temperature of a food rapidly increases, thus shortening the cooking time. By setting the oven pan on a rail 9 a partition is created between cooling air suction ports 6 and 6'. Therefore, air entering into the oven through the suction port 6 flows toward the oven upper chamber and is discharged out of the oven through an exhaust port 7, air entering the oven through the suction port 6' flows toward the oven lower chamber, and is discharged out of the oven through the exhaust port 7'. By adjusting the opening degree of suction ports 6 and 6' and exhaust ports 7 and 7', vapor generated from the food can be controlled to a quantity required for ventilation.

Title: Manufacture of lithium aluminate powder
Inventor: NAKANISHI MIKINORI
IPC: C01F7/04
Filed: 1981-09-08
Abstract: PURPOSE:To obtain finer LiAlO2 powder in the manufacture of LiAlO2 by a chloride method by using LiCl-KCl as a flux. CONSTITUTION:LiOH.H2O and gamma-Al2O3 are prepared as reactive substances, and LiCl and KCl are prepared as a flux. These starting materials are blended in 45:55 weight ratio of reactive substances: flux, 1.02 equiv. ratio of LiOH.H2O/ Al2O3 and 58:42 molar ratio of LiCl: KCl. The blend is dry-pulverized, mixed, heated, held, and cooled to room temp. The resulting product contains a small amount of Li2O formed by adding LiOH.H2O in excess, so the product is washed in water to remove the Li2O, and by drying the washed product, LiAlO2 powder  having a large specific surface area is obtd. The reason that the powder is  obtd. is considered to be that the reaction of LiOH with Al2O3 proceeds at a  low temp. because of the low m.p. of the flux and LiAlO2 crystals grow at a  restricted low speed.
