Title: Steel with superior rolling fatigue characteristic
Inventor: TAKAGI MASAAKI
IPC: C22C38/00
Filed: 1990-10-31
Abstract: PURPOSE:To improve the rolling fatigue characteristics without finely reducing the 0 content of the steel by specifying the composition of oxide inclusions present in the steel and the aspect ratio of the oxide inclusions after processing. CONSTITUTION:The composition (wt.%) of the oxide inclusions present in the steel is set substantially so that SiO2 is 25-80%, Al2O3 is 5-30%, and CaO+MnO is 10-55% (where the total of those oxides is 100%). Further, the >=60% oxide inclusions with a >=3.0 aspect ratio after processing are included. The chemical component composition of the steel is set preferably so that C is 0.15-1.20wt.%, Si 0.15-2.50wt.%, Mn 0.10-3.00wt.%, and Fe and impurities for the rest. This steel contains the oxide inclusions in elongated states by proper amounts, so the rolling fatigue characteristic is improved.

Title: Method and apparatus for eddy-current flaw detection
Inventor: YOTSUTSUJI JUNICHI
IPC: G01N27/90
Filed: 1995-11-14
Abstract: PROBLEM TO BE SOLVED: To detect the size and the direction of a very small flaw by referring to the magnitude of the output signal of a secondary coil obtained at a time when two primary coils arranged so as to be close at distances which can interfere magnetically with each other are excited at an in-phase and an opposite phase. SOLUTION: When two primary coils 2 are excited respectively at an in-phase and an opposite phase, magnetic fluxes as shown by one-dotted chain lines are generated, and eddy currents as shown by broken lines are generated at an object 1, to be inspected, by the magnetic fluxes. When the two eddy currents are synthesized, a synthesized eddy current as shown by a solid line is formed. Then, when the coils are excited at the in-phase, the eddy currents in a direction parallel to the arrangement of the two coils 2 are intensified. When the coils are excited at the opposite phase, the eddy currents in a direction at right angles to the direction of the arrangement of the coils 2 is intensified. In an eddy-current flaw detection method, the sensitivity of a flaw in a direction at right angles to the eddy currents is highest.  When the coils are excited at the in-phase, a flaw in a direction at right angles to the arrangement of the coils 2 is detected with good sensitivity. When the coils are excited at the opposite phase, a flaw in a direction parallel to the coils 2 is detected with good sensitivity. Consequently, the size and the direction of the flaw can be detected on the basis of this relationship.

IPC: H01F1/11
Filed: 1986-12-11
Abstract: PURPOSE:To suppress flocculation of ferrite and to obtain magnetic powder having improved dispersibility by adding fine soft magnetic or antiferromagnetic metallic particles to a sintered body pulverized after a heat treatment and treating the same with a dilute acid while impressing a high-frequency magnetic field thereto. CONSTITUTION:The fine soft magnetic or antiferromagnetic metallic particles are added to the sintered body subjected to the pulverization and the treatment thereof is executed under the impression of the high-frequency magnetic field thereto in a stage for extracting the crystal of hexagonal ferrite by treating the sintered body subjected to the pulverization with the dilute acid. The fine soft magnetic or antiferromagnetic metallic powder to be used is exemplified by chromium, nickel, manganese, molybdenum, etc., and the grain size thereof ranges preferably 0.01-0.5mum. The amt. of said powder to be added is 0.01-0.5wt% by the weight of the sintered body subjected to the pulverization after the heat treatment. A magnetorestriction effect is thereby generated in the ferrite, by which the sepn. between the ferrite crystal and glass phase is accelerated and the fine soft magnetic or antiferromagnetic metallic particles are intruded among the ferrite particles to suppress the flocculation of the ferrite particles. The dispersibility is thus improved.

Title: Intake manifold for engine
Inventor: KAMATA YOSHITO
IPC: F02M35/10
Filed: 1994-11-04
Abstract: PURPOSE: To reduce the installation height of connecting pipes for extraction of intake negative pressure and also reduce the affection of intake pulsation inside a surge tank in an intake manifold. CONSTITUTION: A part of the upper wall part of a surge tank 11 interconnected to the collective part of an intake pipe 7 is expanded toward the outside so as to form an expanded part 12. Also multiple connecting pipes 14 (straight pipes) are connected to the side walls of the expanded part 12, and interconnected to the inside of the swelled part 12. Then a negative pressure response actuator is connected to the connecting pipes 14 so as to take out intake negative pressure from the surge tank 11 as negative pressure source. Because the top end part of the connecting pipes 14 is extended along the upper outer wall surfaces of the surge tank 11, the installation height of the connecting pipes 14 is reduced.  In addition, because the affection of intake pulsation inside the surge tank 11 becomes less apt to be transmitted to the connecting pipes 14 due to volume of interior of the swelled part 12, a uniform and stable intake negative pressure can be taken out from each connecting pipe 14.

Title: Recording-paper edge position detection method using reflective optical sensor, and image forming device
Inventor: TAKADA YUTAKA
IPC: B65H7/14
Filed: 1998-10-03
Abstract: PROBLEM TO BE SOLVED: To adjust reflective optical sensors for detecting the position of recording paper in order, not via manual control, in accordance with dispersion in their characteristics and mounted positions, fluctuations in their environment, and the like. SOLUTION: The recording-paper edge position detection method using a reflective optical sensor detects the edge position of recording paper by radiating light on it and figuring out the output level of the reflected light. As a reflective optical sensor 22 detects edges of recording paper at a first position, another sensor 24 detects the next recording paper at a second position upstream of the first position along the recording paper feed path. Upon such detection of the next recording paper, both recording paper sheets are delivered downstream only by a preset distance set longer than the interval between the first and second positions. With the next recording paper certainly set at the first position, controlled variables for the light emitting part of the reflective optical sensor 22 are controlled until the light receiving part thereof produces a target output level.  Those controlled variables regulated in this way are used to drive the light emitting part and thereby detect edge positions of recording paper.
