Title: Information retrieval device and method therefor
Inventor: KOTANI TAIZO
IPC: G06F17/30
Filed: 1996-02-20
Abstract: PROBLEM TO BE SOLVED: To obtain a relative document via a key word by retrieving the document which includes a synonym of the key word and a word having the same meaning attribute as the key word that are approximate to each other. SOLUTION: A CPU 1 temporarily stores the word serving as an input key word in a RAM 3 and tries to retrieve a word that is completely coincident with the key word out of a document data base. If the coincident word cannot be retrieved, the CPU 1 retrieves a synonym of the key word. That is, the input word stored in the RAM 3 is decomposed into the words of minimum units and the words which are not used for the retrieval are eliminated, so that a synonym retrieval key word is obtained. Thus the CPU 1 refers to a word associative dictionary based on the obtained key word to acquire a synonym and a meaning attribute code.  Then the CPU 1 retrieves a document that includes the synonym and also has a word having the same meaning attribute acquired from a meaning attribute system dictionary as the key word in a range of the prescribed length including the said synonym out of the document data base of a hard disk storage 7.

Title: Solidified grain granulator
Inventor: YOSHIOKA TERUO
IPC: B01J2/26
Filed: 1993-01-28
Abstract: PURPOSE:To granulate imperfectly solidified grains as only the fly ashes or the cement or only the mixture composed thereof or the imperfectly solidified grains obtd. by slightly adding water thereto in addition to the desired solidified grains are discharged from the outlet of a fly ash solidifying and kneading machine for adding the cement to the fly ashes and hydrating the mixture. CONSTITUTION:A solidified grain granulator 20 is disposed under the discharge port 1a of the fly ash solidifying and kneading machine 1. Granulating belts 26, 36 are respectively put around pulleys 22 and 24 as well as 32 so that the transportation side rises from below to above. The imperfectly solidified grains tend to be lowered by gravity and receive the force to rise by friction with the granulating belts 26, 36, thereby the grains are vertically moved on the granulating belts. The grains are compacted by incorporating the fly ashes and the cement therein during this time. Their own gravitational force is made larger than the force by the friction as the grains grow bigger. Such grains fall from the upper solidified grain granulator 20a to the lower solidified grain granulator 20b and are further subjected to the granulation effect in the lower solidified grain granulator 20b. These grains fall in the form of the solidified grains onto a curing conveyor 2.

IPC: H03B5/32
Filed: 1988-02-16
Abstract: PURPOSE:To provide a wide range of temperature compensation by providing plural programs with a temperature detection characteristic of an ambient temperature detection means and selecting a program in response to the ambient temperature detection means in use. CONSTITUTION:A voltage from a regulator 40 is given to a CPU 30, a temperature detection part 32, and a D/A conversion part 36. The ambient temperature detection means 32 consists of a variable resistor 42 connected in series with a fixed resistor 44 and a temperature reply element 46 such as a thermister. The resistance of the thermister is decreased as well known as the ambient temperature increases accordingly. Thus, since the A/D input terminal of the CPU 30 receives a power voltage divided by resistors 42, 44 and the thermister 46, the terminal receives a voltage varied with the ambient temperature. The variable resistor 42 acts like correcting the dispersion in the thermister and the power voltage to make the A/D input voltage at room temperature constant. The comparison data between the data of the A/D input voltage and the ambient temperature is programmed in a ROM part of the CPU 30.
