Title: Production of perovskite-type multiple oxide powder
Inventor: OKABE KAZUMI
IPC: C01G25/00
Filed: 1990-10-16
Abstract: PURPOSE:To obtain the subject powder having increased surface area by reacting a specific alkoxide with an alkaline-earth metal hydroxide in the presence of an alkali metal hydroxide, insolubilizing the reaction product with an alkali metal carbonate, separating the product from the reaction mixture by filtration, converting to a complex salt with acetylacetone and baking the salt. CONSTITUTION:An alkaline-earth metal hydroxide such as Ba(OH)2 is dissolved in boiling water in the presence of 1-4 times mol of an alkali metal hydroxide such as NaOH, the solution is added with an alkaline-earth metal hydroxide and an equimolar amount of a <=15C alkoxide of a tetravalent metal (e.g. Ti isopropoxide) and the components are made to react with each other at 60-95 deg.C. After the reaction, the reaction product is insolubilized by adding <=5mol% of an alkali metal carbonate such as K2CO3. The obtained reaction product powder is separated by filtration, washed with warm water and the pH of the washing liquid is maintained at >=10 by adding N,N'-dimethylbenzylamine, etc. The produced powder is dispersed in pure water, added with <=10mol% of acetylacetone and made to react at 90-95 deg.C. The obtained complex salt is separated by filtration, dried and calcined at 400-600 deg.C to obtain a perovskite-type multiple oxide powder expressed by the general formula ABO3 (A is alkaline-earth metal element; B is tetravalent metal element).

Filed: 1989-10-27
Abstract: PURPOSE:To shorten the maximum delay time for transfer of data with an interruption having high importance by deciding previously the quantity of data to be transferred in a single time based on the importance of each interruption. CONSTITUTION:A transfer data unit setting device 9 is provided to a signal processor 1 to set the data transfer unit in accordance with the importance of each interruption together with a data transfer unit informing signal line 10 which informs an input/output device 3 of the data transfer unit.
