Title: Information retrieval method and device therefor, and medium for storing information retrieval program
Inventor: KUBOTA RIE
IPC: G06F17/30
Filed: 1996-03-25
Abstract: PROBLEM TO BE SOLVED: To retrieve a large quantity of documents stored in a disk, etc., at a high speed and with desired fuzziness allowed. SOLUTION: A character chain file included in a n index file stores the variable length chains, fixed length chains and delimitation patterns and their corresponding document numbers and intra-document position numbers and shows the positions of these numbers in a position information file which stores them. An extension character chain file stores the extension character chains and shows the positions of the variable length chain numbers and inter-variable length chain position numbers corresponding to the expansion character chains in an extension position information file which stores those chain numbers and chain position numbers. Thus, a document including the character strings which have the arrays of characters similar to a designated character string is retrieved at a high speed and by means of the index file.  In other words, a character string similar to the desired one to be retrieved is chosen out of a document and the degree of similarity is turned into the numerical value from two points of view, i.e., the number of continuous coincident characters and the number of excessive intervenient characters.

Title: Semiconductor integrated circuit
Inventor: IWAHASHI HIROSHI
IPC: H01L29/788
Filed: 1982-04-24
Abstract: PURPOSE:To apply the optimum potential to the source of a memory cell, and to execute the stable writing by providing an impedance means between the 3rd MOSFET and a power supply to drop the voltage for a source potential control circuit of a memory cell. CONSTITUTION:An MOSFET3 of a source potential control circuit 40 supplies the common potential VS* to the source of each memory cell in order to keep the source potential at a fixed level. An MOSFET7 of a depression mode is put between the drain of the MOSFET3 and the source of a MOSFET2 as an impedance means. This FET7 produces a voltage drop to set the drain potential of the FET3 at the same level as the drain of an actual memory cell. As a result, the source potential VS* of the memory cell is set at the minimum level to avoid the punch through of the memory cell. This ensures the stable writing.

Title: Control system for moving speed of cursor display
Inventor: YAMAZAKI NOBUO
IPC: G06F3/038
Filed: 1987-03-25
Abstract: PURPOSE:To improve the working efficiency in the titled control system by delivering the tilting angle of a control lever after converting it into the data on the cursor moving speed different from the normal level in case the change of a variation rate is instructed. CONSTITUTION:An instructing means 12 gives an instruction for change of the variation rate of the cursor moving speed. Thus a cursor address control part 11 outputs the tilting angle of a control lever 1 after converting it into the data on the cursor moving speed different from a level changed in a normal state. In such a way, the cursor moving speed is changed. Owing to the instruction of the means 12, it is possible to change the cursor speed in response to the details of a part indicated by a cursor even in case the lever 1 is tilted by an extent equal to a normal level. As a result, both the operability and the working efficiency can be improved in a cursor speed control system.

Title: Fuel closing reference positional automatic compensator for exhaust gas recirculating valve in exhaust gas recirculating control equipment
Inventor: HASEGAWA SHIYUNPEI
IPC: F02D21/08
Filed: 1981-05-08
Abstract: PURPOSE: To contrive correct exhaust gas recirculating control by automatically compensating the full closing reference position of an exhaust gas recirculating valve, in a fuel feeding control equipment to control the air-to-fuel ratio using an electronic means.  
     CONSTITUTION: In addition of performing the regular EGR operation on the basis of lift command values in response to the absolute pressure PB for the number of revolution Ne in the engine, discrimination whether or not it is at EGR operation is done on the basis of the difference between the actual lift rate LACT of the valve body of an exhaust gas recirculating valve 19 and the valve lift command value LMAP which is selected from the actual number of engine revolution Ne and the absolute pressure PB. However, in the exhaust gas recirculating valve 19, the zero reference position of the valve opening degrees, namely the full closing position of the valve body 19a is changed, therefore a lift sensor 24 does not give signals as output for correctly indicating the actual valve lift rate. Thus, in case where the condition of the lift command value LMAP=0 has been continued for the determined time (approximately 3sec), the future EGR rate can be controlled in such a way that the lift detecting value from the lift sensor 24 at that time is assumed as the new zero reference position.

Abstract: PURPOSE:To reduce the deterioration in the read quality due to a digital error liable to take place on a border line or a halftone by scanning plural strings of optical sensor arrays simultaneously and applying arithmetic processing to plural obtained video signal outputs. CONSTITUTION:A scanning circuit 4 sequentially scans to obtain three video signal outputs simultaneously from a read light sensor array 1, a succeeding line light sensor array 2 and a preceding line light sensor array 3. Since the arrays 1-3 are arranged with the resolution in the subscanning direction, they are video signals corresponding to the n-th picture element of (m+1)th, m-th and (m-1)th columns. On the other hand, an output terminal of the array 1 connects to a delay device 5 and the video signal of the m-th column and (n-1)th picture element being one preceding picture element is outputted at the output. The adder 6 applies arithmetic processing to the output of the array 2 and the output of the array 3. The output of the adder 6 is subtractor from the output of the array 1 with a subtractor 7. Thus, notch due to digital error is reduced and the edge is able to be emphasized, then a sharp picture is obtained.
