Title: Indexing system for japanese document system
Inventor: OMACHI EIKO
IPC: G06F17/21
Filed: 1986-05-02
Abstract: PURPOSE:To obtain an indexing system for a Japanese document system where only the pages of the index words of designated areas are listed as reference pages, by designating the index words to be retrieved out of sentences. CONSTITUTION:The originals of input sentences are defined as the index words with pages and stored in a memory medium in the order of index words for Japanese sentences, Western language sentences and other language sentences. An index means extracts the index words with pages out of the memory medium to decide the presence or absence of the same index words. If the absence of the same index words is confirmed, the processing is finished. While the presence or absence of the same pages is checked if the same index words are detected. If the same pages are not detected, plural pages corresponding to the same index words are listed as reference pages. Then the corresponding page is defined as a reference page and other undesired index words listed as the same index words are deleted. When the same pages are detected, the same index words are defined as a single index word. Then the headers of index words are added for the Japanese sentences, the Western language sentences and other language sentences to perform editing. Then these sentences are stored in the form of the image of a print list and also printed.

Title: Method of and device for correcting single bit error* and double bit error using double bit error detecting logic and syndrome bit memory
Inventor: JIEEMUSU HAAMAN SHIYUNEEMAN
IPC: G06F12/16
Filed: 1978-08-25
Abstract: A method of and an apparatus for obtaining double bit error correction capabilities in a large scale integrated (LSI) semiconductor memory system using only single bit error correction, double bit error detection (SEC, DED) logic are disclosed. The method is based upon the statistical assumption that in a large scale integrated semiconductor memory, substantially all errors in the data bits that make up a data word are initially a single bit error and that increasing multiple, i.e., double, triple, etc., bit errors occur in a direct increasing ratio of the use or selection of the data word. In the present invention, all data words are priorly tested to be error free. Subsequent detection of single bit errors results in the correction of the single bit error and the storage of the single bit error correcting syndrome bits in a syndrome bit memory. Subsequent detection of double bit errors, in the previously single bit error detected and corrected data words, results in the correction, by single bit error correcting syndrome bits, of the previously detected single bit error. This single bit error corrected data word is then again single bit error corrected, i.e., two successive single bit error corrections, to provide a twice corrected double bit error data word.

Title: Combustion device
Inventor: OGINO TOSHIRO
IPC: F23D3/10
Filed: 1988-04-26
Abstract: PURPOSE:To reduce the generation of tar, to shorten an extinguishing time, and to reduce the occurrence of overcombustion, by a method wherein a slitform opening is formed circumferentially of the lower part of an outer grate, and a space between the outer grate and a wick outer cylinder is insulated thermally. CONSTITUTION:Vaporization of fuel is continued by means of a combustion heat and an air flow fed through pores 11 in the vicinity of a wick 1 by means of heat draft generated in a combustion chamber 8. Air required for combustion is diffused and mixed with vaporized gas fed in the combustion chamber 8 through air holes 11 formed in inner and outer flame cylinders 6 and 7, and the air-fuel mixture is raised within the combustion chamber 8 as it is burnt. Since, though a combustion amount at the lower part of the combustion chamber 8 is increased, transfer of heat from an outer grate 5 to a wick outer cylinder 3 is disconnected by means of a slitform opening part formed in the lower part of the outer grate 5, the increase in temperature of the wick outer cylinder 3 is decreased, and transfer of heat from the wick outer cylinder 3 to a wick 1 is decreased.
