Abstract: PROBLEM TO BE SOLVED: To easily retrieve a desired entry word regardless of a slight error in a keyword in an information retrieval device which retrieves and displays information corresponding to the entry word. SOLUTION: When an input part 12 is operated to input a keyword corresponding to the desired entry word, the keyword is successively compared with individual entry words in a data base 13a to discriminate it completely coincides with each entry word or not. If there is not any entry word which the keyword completely coincides with, the numbers of characters from the head which coincide with those of the keyword and the numbers of characters from the end which coincide with those of the keyword are counted for individual entry words and are compared, and each entry word is stored in a head coincidence retrieval-entry word memory 16d1 together with its number of coinciding characters if the number of characters from the head which coincide with those of the keyword is large,  and each entry word is stored in an end coincidence retrieval entry word memory 16d2 together with its number of coinciding characters if the number of characters from the end which coincide with those of the keyword is large. An entry word of which the number of coinciding characters is largest out of entry words obtained by head coincidence retrieval and end coincidence retrieval is taken as a retrieval entry word and is stored in a retrieval word list memory 16c and is displayed on a liquid crystal display part 17.

Filed: 1988-06-09
Abstract: PURPOSE:To prevent instability of combustion, e.g. blow off, due to blow off even when high load combustion is made on fuel gas having a slow burning velocity and to enable increase of a combustion load by a method wherein burner ports are blinded at intervals of at least two burner ports or up to four burner ports.

When fuel-air mixture of combustion air and fuel gas is increased for high load combustion, the velocity of flow of the fuel-air mixture injected through the burner ports is increased to a value higher than a flame propagation speed. Flame F is blown up to cause the occurrence of blow off. However, since at the blind part 12, recirculation of combustion gas is produced as shown by an arrow mark, fuel-air mixture injected through the burner ports situated around the blind part 12 is continuously ignited by means of high temperature recirculation gas to perform stable combustion, and high load combustion being higher than that of a combustion plate having no blind part 12 can be achieved.
