Filed: 1998-02-18
Abstract: PROBLEM TO BE SOLVED: To dissolve a sense of incongruity in a conventional retrieval result that data including a key word for retrieval is retrieved in a lower order than the data including no key word for retrieval when the retrieval result is outputted. SOLUTION: A data retrieving device is provided with a matching degree with title calculating means 4 to calculate a matching degree of the data with the key word acquired from a title, a matching degree with text calculating means 5 to calculate the matching degree of the data with the key word acquired from a text and a total matching degree calculating means 6 to calculate a total matching degree in which the matching degrees acquired from the both means are totaled. Thus, unnecessary data for a user is excluded from the retrieval result and the retrieval result is more exactly obtained. Furthermore, the data including the key word for retrieval in the title is retrieved in an upper order.

Title: Powder developer ejection type imaging apparatus
Inventor: SHIBATA TOKIFUMI
IPC: G03G15/05
Filed: 1999-02-15
Abstract: PROBLEM TO BE SOLVED: To form a plurality of dots on a recording medium for respective through holes by applying a voltage to a deflection electrode disposed in the vicinity of the through hole independently from individual electrodes and generating a new field for varying the flying direction of developer passing through the through hole. SOLUTION: When a pulse voltage having a peal level of +250V, for example, is applied to a deflection electrode 40L and a pulse voltage having a peal level of -50V, for example, is applied to a deflection electrode 40R, a field stronger than the field already formed between a developer carrying roller and a back face electrode roller by first and second bias power supplies and urging a developer to the deflection electrode 40L side is formed. Consequently, the developer held at the developer carrying roller part facing a corresponding through hole 34 is separated from the developer carrying roller and enters, as a group, into the hole 34. The developer flies while being deflected to the deflection electrode 40L side with respect to the direction of deflection axis 43 by means of the deflection electrode 40L and forms a dot centering a point 601.

Title: Information recording/reading method
Inventor: IKEDA HIDEO
IPC: G06K17/00
Filed: 1988-02-17
Abstract: PURPOSE:To highly sensitively read information even when detecting elements cannot be stuck by changing the magnetic characteristics of a part of the base material of ferromagnetic material, writing the information, impressing and magnetizing a magnetic field in parallel to a surface, detecting a leakage flux, and attaining reading. CONSTITUTION:When laser beams 2 are irradiated on a base material 1 of a cold rolled steel sheet, a sharp heating cooling operation is applied to an irradiated part 3, an extreme residual stress is generated, the magnetic characteristics of the part 1 are changed from those of the circumferential area, and holding force becomes larger than that of the circumferential area. When the magnetic field is impressed and magnetized over the whole writing area in parallel with the base material surface, large residual magnetization is generated in the part where the laser beams are irradiated. By using hole elements arranged vertically to the base material surface so as to detect the leakage magnetic flux in parallel with the base material surface due to the residual magnetization, the recorded information can be highly sensitively read. Thus, by writing the necessary information by means of a symbolized bit pattern, it can be utilized as the information recording system of a marker, etc.

Title: Tube coupling for soft tube
Inventor: NAKAMURA RYOICHIRO
IPC: F16L33/23
Filed: 1999-02-15
Abstract: PROBLEM TO BE SOLVED: To easily hold water stop performance by providing a main body having a diametrically expansive part of a tube end socket, a first screw on the inside surface and a stopper, rubber packing and a bolt forming a second screw on an outside surface and a ring housing part on an inside surface. SOLUTION: When connecting mutual tubes 12 by a tube coupling 10, an interval L between the inmost end surface of a diametrically expansive part 20 and a tip surface of a bolt 16 is set large to reduce insertion resistance of the tubes 12 to reduce compressive force imparted to rubber packing 26. While, a metallic or hard plastic reinforcing in-core 40 is installed in an end part of the tubes 12. When inserting the tubes 12 into a socket 18 from an end part of the bolt 16, a fastening ring 36 of a ring housing part 32 and the packing 26 are diametrically expanded in order by a taper surface of the in-core 40, and the ring 36 engages with an outside surface of the tubes 12, so that the packing 26 is brought into pressure contact with an outside surface of the tubes 12. When the tip of the tubes 12 abuts to a stopper 24, insertion of the tubes 12 is completed.  Fastening torque of the bolt 16 is adjusted, and proper compressive force is imparted to the packing 26 to thereby easily hold water stop performance of a joining part.

Title: Air-fuel ratio control device for engine
Inventor: MATSUMOTO MIKIO
IPC: F02D41/14
Filed: 1996-02-23
Abstract: PROBLEM TO BE SOLVED: To prevent emission from being degraded by setting a greater gain of an air-fuel ratio feed-back in an early stage of shifting from a steady condition to an accelerating condition, widening an effective air-fuel ratio of catalysts, and thereby correcting slipping as a result of the air-fuel ratio feed-back. SOLUTION: While an engine is in operation, it is judged by a control unit whether a condition of an air-fuel ratio feed-back (hereafter, FB) can be made or not first, when it is recognized to be YES, it is also judged whether a condition is established or not, in which a gain of the air-fuel ratio FB can be made by a catalyst upstream sensor, and when its result is recognized to be YES, next, the output of the upstream sensor is read in, and if an air-fuel ration is rich, the result of the previous judgement is referred, and when the previous air-fuel ratio is lean, the quantity of step correction (PR) is computed in order to make an air-fuel ratio lean. An air-fuel ratio is thereby corrected with high accuracy by correcting the balance between the aforesaid PR and PL which is computed when an air-fuel ratio is lean, based on the output of a catalyst downstream sensor.

Title: Radioactivity measuring method
Inventor: MATSUMOTO KANAME
IPC: G01T7/02
Filed: 1980-03-21
Abstract: PURPOSE:To check the settlement of radioactivity and prevent time lag or the like of a measured value with higher accuracy by measurig a sample water with addition of a substance which tends to be pasty by dissolving in water forming a sticky liquid or a gel. CONSTITUTION:When measuring radioactivity of a radioactive waste liquid from a nuclear power generation plant, a substance such as CMC, glue, gelatin, starch paste, cone starch and agar is added thereto to check the settlement of a settling radioativity, which tends to be pasty when it is dissolved in water, forming a sticky liquid or a gel. If necessary, after the sample water is heated and agitated to be  pasty, the radioactivity thereof is measured in a measuring vessel. This prevents  difference in the measured value due to time lag from the sampling to the measurement and overcomes personal difference in the measured value depending on a  person who carries out the measurement.

IPC: B32B33/00
Filed: 1980-03-21
Abstract: PURPOSE: To develop visually three dimensional appearance by a method wherein an org. foaming agent is used and a particle thereof is floated and exposed to a coating surface without foaming said foaming agent to lower a gloss degree of said part.  
     CONSTITUTION: An opaque ground coat layer 2 and an optional pattern 5 consisting of a pattern 3 to be formed into a protruded part and a pattern 4 to be formed into a recessed part are printed on a base material 1. Subsequently, a transparent or a translucent synthetic resin containing an org. foaming agent is coated thereon to provide a synthetic resin layer 6 with a low gloss degree. Because the synthetic resin layer 6 is reduced in the gloss degree by a phenomenon wherein a particle of the org. foaming agent contained in said synthetic resin composition is exposed to the coating surface of the resin layer and light is subjected to diffused reflection, it is not necessary to foam said foaming agent. An ink or a paint forming a skin film with a high gloss degree is partially coated on said synthetic resin layer 6 to obtain the decorative board.
