Inventor: KAMIYA SHIN
IPC: G10L15/183
Filed: 1989-02-16
Abstract: PURPOSE:To obtain the correct voice recognizing result with a simple process by producing a connection matrix (syntax structure/meaning restricting conditions) with use of a word meaning dictionary and the example sentences. CONSTITUTION:Several example sentences produced with use of the words registered in a word meaning dictionary 3 are divided every paragraph and inputted to a meaning analyzing part 2. Then two types of grammar-meaning pairs are produced to the independent words and the affixial words of various paragraphs with use of the pairs of parts of speech and meanings (grammar- meaning pairs) of the dictionary 3. Thus plural grammar-meaning pairs are used as rows or columns for production of an inter-paragraph connection matrix. The part 2 refers to this connection matrix stored in an inter-paragraph connection matrix store part 4 and selects only a paragraph string that satisfies the syntax structure/meaning restricting conditions out of those paragraph strings obtained from the paragraph lattices received from a voice recognizing part 1. Then the selected paragraph string is outputted as a sentence. Thus the voices are correctly recognized in a simple way.

Title: Treatment of halogenated aliphatic hydrocarbon
Inventor: UKISU YUUJI
IPC: A62D3/34
Filed: 1998-02-19
Abstract: PROBLEM TO BE SOLVED: To realize an efficient decomposition and a procedure to make chemical compounds harmless under moderate conditions by performing the dehalogenation and the treatment to make the chemical compounds harmless through a chemical reaction in the presence of 2-propanol, a catalyst and an alkali compound. SOLUTION: A chemical compound which can be treatment to be harmless is aliphatic hydrocarbons which have at least, one halogen atom as a substituent group regardless of whether it being saturated or unsaturated or straight-chain or branched. For example, chemical compounds such as trichloroethylene and tetrachloroethylene are treated in 2-propanol. For a catalyst, one kind selected from platinum, palladium or the like or their oxides is borne by a carrier such as silica gel, alumina, carbon or the like. An alkaline metal hydroxide such as lithium hydroxide or sodium hydroxide as an alkaline compound and a catalyst are added to a solution obtained by dissolving halogenated aliphatic hydrocarbons into the 2-propanol and thus a suspension is obtained and then is subjected to a dehalogenation reaction.  Further, the suspension is dehaloganated under moderate conditions of normal temperature and normal pressure. Consequently, it is possible to make the suspension harmless in a short time and save on energy and running cost.

Title: Diaphragm type formed bellows and its manufacture
Inventor: OKADA HIDEKI
IPC: B21D15/10
Filed: 1998-02-19
Abstract: PROBLEM TO BE SOLVED: To improve durability so as to be also used in such a use as generating not only a deformation in a compressing direction but also a deformation in an extending direction and a pressure difference between inside and outside a bellows. SOLUTION: Working is executed by a working force becoming a specific pressure of <=700 Kgf/cm<2> when a material of 20%-40% in elongation is used and working is executed by the working force becoming the specific pressure of <=100 Kgf/cm<2> when a material of >40% in elongation is used so that the ratio R min/t of the minimum bending radius R min to a plate thickness (t) becomes >=0.8. In such a,manner, a compressed wrinkle by strong working is not generated inside bending in an R shape part in a tip end and stress is not concentrated in the part. Therefore, durability is improved because durability is not reduced even though a bellows is used in a tensile side and also stress is not concentrated as well even though the pressure difference is generated inside and outside the bellows.
