Title: Similar document retrieving device, similar document retrieving method and storage medium recorded with program for retrieving similar document
Inventor: TANOSAKI YASUO
IPC: G06F17/30
Filed: 1998-03-06
Abstract: PROBLEM TO BE SOLVED: To enhance retrieving accuracy when a similar document is retrieved by extracting a composite word from a retrieving key document and a document to be retrieved. SOLUTION: When the composite word, i.e., 'brush character address printing function' exists in the retrieving key document or the document to be retrieved and the maximum number of connections is specified as three, all the composite words like 'brush character address', 'character address printing', 'address printing function', 'brush character', 'character address', etc., consisting of the number of words to be equal to or less than the maximum number of connections are extracted from each document, appearance frequency of the composite words is calculated and a degree of similarity between the retrieving key document and the document to be retrieved is calculated.  Since different composite words to characterize the documents with specified contents are thoroughly extracted, a more proper degree of similarity between the documents is calculated and highly accurate retrieval of similar document intended by a user is performed.

IPC: G01J3/36
Filed: 1984-03-22
Abstract: PURPOSE:To make the saturated charge amount of a detecting element constant over a wide wavelength range by varying the photodetection area of each detecting element with light intensity. CONSTITUTION:Detecting elements 10-1-10-n are so formed as to have an area distribution proportional to the wavelength of the intensity of dispersed light reaching a photodiode array.

Abstract: PURPOSE:To provide stable seaking operation at a higher speed in accordance with a device characteristic for the fluctuation factor of a linear motor characterisitic, a control circuit characteristic and power source fluctuation, etc., at the time of the seeking operation of an optical head. CONSTITUTION:The current signal of the linear motor in the seeking operation of a driving circuit 14 is fetched into a microprocessor 7 by an A/D converter 12 and the optimum table of a speed reference table stored in a ROM6 is selected from a maximum acceleration current at a seeking time and an average driving current at a speed-reducing time and the optical head is seeked at a high speed. Thus, optimum acceleration is set always for the dispersion of a circuit characteristic, the dispersion of the constant of linear motor power, the fluctuation of source voltage and the stable seeking operation with high reliability is performed. Further, a nacessity that the acceleration is set lower estimating the lowering of a margin for generating acceleration due to the fluctuation factor is eliminated and the seeking operation is quickened.

Title: Monitoring circuit for bias current of laser-diode
Inventor: NISHIE MITSUAKI
IPC: H01S5/042
Filed: 1980-04-30
Abstract: PURPOSE: To enable to monitor bias currents under a binary system of the output of a comparator by a method wherein a temperature sensing circuit is mounted which changes following the temperature characteristics of a laser diode, and the output of the temperature sensing circuit is forwarded to the comparator.  
     CONSTITUTION: When the temperaure of a laser diode LD changes to a low temperature from a high temperature, the resistance value of a sensor 2 increases. Thus, when bias current Io is within a proper value, the input of a comparator II is kept within a set value. Consequently, a LED4 of a normal condition displaying section III emits light. When the currents Io exceed the proper value, on the other hand, the input of the comparator II also exceeds the set value. as a result, the LED7 of an abnormal condition displaying section IV emits light. In this case, a bias circuit of the diode LD decreases the current Io because a feedback circuit flowing the proper currents Io in response to temperature is installed, thus hardly changing the output of a temperature sensing circuit I, then keeping the output within the set value. Accordingly, the quality of a function of the feedback circuit can be determined by monitoring the adequacy of the Io current.

Title: Method for rolling high si steel sheet
Inventor: FUJITA FUMIO
IPC: B21B3/00
Filed: 1987-03-11
Abstract: PURPOSE:To improve rolling efficiency and to relax restricting condition to an equipment by executing hot rolling under giving difference between the peripheral speeds having the special condition to the upper and lower work rolls. CONSTITUTION:At the time of rolling the hot-rolled steel plate having 4.0-7.0wt.% Si content at the temp. range of 100-400 deg.C, the rolling giving the difference of peripheral speeds to the upper and lower work rolls is executed. That is, by setting the roll peripheral speed at the low speed side to more than the inlet speed of the material and the roll peripheral speed at the high speed side to less than the outlet speed of the rolled material, the difference between the peripheral speeds is given to the upper and lower work rolls. By this method, as the effect to the rolling load by the friction coefficient at the time of rolling is reduced, the rolling pressure can be reduced to low. Therefore, the rolling reduction ratio per one pass is reduced and the rolling efficiency is improved by reduction of consumption of energy for heat insulating and shortening of rolling time. As the sheet rolling can be executed by work roll having ordinary diameter, the restricting condition to the equipment is relaxed.

Abstract: PROBLEM TO BE SOLVED: To provide a display element in which high-precision, highreliability, and colored display is possible. SOLUTION: A negative electrode 2 comprising material of a low work function for injecting electrons is formed on a surface (upper surface) of a first substrate 1, and a light emitting layer 3 is formed further on a surface (upper surface) of it.

Surfaces of the light emitting layer 3 and the carrier transport layer 6 are tightly applied to each other to form an electric junction part 7 to compose a light emission element. The holes injected from the transparent electrode 5 are transported through the carrier tranpsport layer 6 to be injected to the light emitting layer 3.  The electrons are directly injected from the negative electrode 2 to the light emitting layer 3, thereby light is emitted by recombination of the electrons and the holes inside the light emitting layer 3 or around an interface of the hole transport layer 6.

IPC: G01F1/66
Filed: 1990-03-09
Abstract: PURPOSE:To measure a flow velocity with high accuracy by arranging a transmission- side ultrasonic wave vibrator and a reception-side ultrasonic wave vibrator nearly at right angles to each other on the cross section where the orientation direction of the vibrators crosses the axial direction of control at right angles. CONSTITUTION:The transmitting ultrasonic wave vibrator 1 and receiving ultrasonic wave vibrator 2 are fitted to a conduit 3 at such an interval that they slant at specific angles to the travel direction of the conduit 3 and at almost 90 deg. viewed from the axis direction of the conduit 3. An ultrasonic wave which is generated by the vibrator 1 is propagated in its directional area 5 and reflected at an irregular part of liquid 4, e.g. a blood corpuscle when the liquid 4 is the blood corpuscle. When the liquid 4 flows at a certain flow velocity, the frequency of the reflected ultrasonic wave varies by Doppler effect in proportion to the flow velocity. A wave which is generated in the area 5 of the vibrator 2 as to the reflected ultrasonic wave is received by the receiver 2 and converted into a voltage signal, which is sent to the electric circuit part of the measuring instrument 22. Then the flow velocity, flow rate, flow direction, etc., of the fluid 4 are calculated in the measuring instrument 22 and the results are displayed.

Filed: 1984-03-23
Abstract: PURPOSE:To offer a basic circuit suitable for the fuzzy logic by connecting a wired OR to an output of a current mirror whose input consists of an FET and an input current source. CONSTITUTION:The limit difference circuit consists of the current mirror 1 comprising a P-MOSFET, wired OR, diode 2, two current source 3, 4 and an output terminal 5. The current source 3 having a sweep-out current Ix and the output terminal 5 via a diode 2 in opposite polarity to the sweep-out direction of the current mirror 1 are connected to the output drain. Since the current Ix is drawn by the current source 3, an output current of Iz=Ix-Iy is sucked through the diode 2 from the terminal 5 when the relation of Ix>Iy exists. In case of Ix<=Iy, the output current of Iy-Ix is about to be flowed forcibly, since it is blocked by the diode 2, the current flowing to the terminal 5 is zero.
