Title: Similar document retrieval system and storage medium used for same
Inventor: ISHIZUKA IKUTO
IPC: G06F17/30
Filed: 1997-08-28
Abstract: PROBLEM TO BE SOLVED: To obtain the efficient similar document retrieval system in consideration of the inclusion relation between documents of important concepts without requiring preparations and maintenance for external information such as a word dictionary and a syntax rule by performing a dividing process based upon the inclusion relation for word extraction based on the character kind division. SOLUTION: A word extraction part 1 divides the text of an input document 5 by character kinds and calculates the word groups of the input document 5 and their in-document frequencies. An index update part 2 reflects the word groups and in- document frequency information of the input document 5 on indexes 7. A retrieval part 3 finds the importance of the words of the input document 5 from the in-document frequencies of the words of the input document 5 and frequency information of the respective words in the whole document held in the indexes 7 and finds the similarity to documents containing the words by referring to the indexes 7 from a word of high importance. This process is repeated until certain calculation end standards are met. Then the contents of a document having high similarity are taken out of a document data base 8.  A document storage part 4 adds a pair of a document identifier and document contents to the document data base 8.

IPC: G11C5/00
Filed: 1988-09-19
Abstract: PURPOSE:To prevent an unnatural force from being applied between a memory cartridge and a connector by driving a motor to move the memory cartridge in the direction of cartridge insertion and drawing in the cartridge through a spring to load it to the connector and applying a prescribed energizing force only at the time of loading operation to the connector. CONSTITUTION:When a memory cartridge 10 is inserted and a second slide member 40 is moved in the direction of cartridge insertion by driving the motor, a drawing-in force is applied to the memory cartridge 10 through a spring 46, a first slide member 30, and an engaging member 60 from the second slide member 40 and is moved in the direction of cartridge insertion. When the second slide member 40 is moved to a prescribed position, the memory cartridge 10 is loaded to a connector 26, and a prescribed energizing force is temporarily applied through the spring 46. Thus, the memory cartridge 10 is surely loaded to the connector 26, and an unnatural force is not applied between the memory cartridge 10 and the connector 26.

Abstract: PURPOSE:To enhance detection accuracy and a frequency characteristic, by providing the voltage converting part with an operational amplifier connected to the output terminal of a current transformer on the input side thereof. CONSTITUTION:The output terminal of a current transformer 13 is directly connected to the non-inversion input terminal (+) and inversion output terminal (-) of an operational amplifier 14 and the input terminal (+) is connected to a ground line GND. An absolute value amplifying circuit 16 is equipped with a plurality of resistors R, operational amplifiers 17, 18 and diodes 19, 20 and takes the absolute value of the voltage value at the output terminal of the amplifier 14 to output the same to the output terminal of the amplifier 18 and outputs DC voltage across both terminals of the smoothing capacitor 22 connected through a resistor 21. By this constitution, the secondary current of the current transformer 13 flows through the loop consisting of the feedback resistor 15 and output terminal of the amplifier 14 and the ground line GND but, since the input terminals of each operational amplifier is regarded as in an imaginary short state in general, the load impedance of the current transformer 13 becomes almost zero. Therefore, detection accuracy and a frequency characteristic can be enhanced.

Abstract: PURPOSE:To steepen attenuation characteristics at a frequency value lower than a passing frequency band by setting up the length of an inner conductor of a band pass filter having a higher passing frequency to a value slightly longer than 1/4 wavelength. CONSTITUTION:The length l3 of the inner conductor 9 of a comb line type band pass filter ..(BPF) 31 is set up to a value slightly shorter than 1/4 wavelength of the center frequency of passing band frequency of the BPF 31. Thereby, attenuation characteristics on the side higher than the passing band are steepened. On the other hand, the length l4 of the inner conductor 10 of a BPF 32 is set up to a value slightly longer than the 1/4 wavelength. Thereby, the attenuation characteristics on the side lower than the passing band are steepened and mutual coupling between both the inner conductors goes to weak electrostatic coupling C. Therefore, the mutual interval between both the conductors can be minimized.

Abstract: PURPOSE:To obtain such a plastic molded type semiconductor device that the cracking of the plastic molded section of a resin, etc., of a rectangular chip caused by stress produced in a rectangular semiconductor chip can be prevented by providing notched grooves near central sections on the longer sides or each side of the semiconductor chip. CONSTITUTION:In this plastic molded type semiconductor device mounted with a rectangular semiconductor chip 1, notched grooves 10 are provided near central sections on the longer sides or each side of the chip 1. For example, notched grooves 10 for relieving stress are provided near central sections on the longer sides of a flat rectangular DRAM 1 of 16.48mmX8.54mm in size sealed with an SOJ plastic molded type package 2. Since the grooves 10 are provided near central parts on the longer sides or on each side of the semiconductor chip where the maximum stress is generated, each side of the chip 1 apparently becomes shorter and generated stress can be reduced. Therefore, the adhesion between the chip 1 and sealing plastic material, such as a resin, etc., can be improved and, at the same time, the reflow-crack strength and moisture resistance reliability of this semiconductor device can be improved.
