  • Patent number: 8337011
    Abstract: An inkjet recording sheet for forming an image using aqueous pigment ink that includes a substrate and an ink-receiving layer formed on the substrate. The ink-receiving layer is obtained by applying, on the substrate, a coating composition containing: a cationic acrylic silicone emulsion-based resin having a hydrolyzable silyl group as a crosslinking component; a cationic polyether-based urethane resin; and a carbodiimide group-containing resin, followed by curing the applied coating composition. In the coating composition, the content of the cationic acrylic silicone emulsion-based resin is 2 to 7% by mass, the content of the cationic polyether-based urethane resin is 88 to 94% by mass, and the content of the carbodiimide group-containing resin is 2 to 6% by mass in terms of solid matter.

  • Publication number: 20110159215
    Abstract: The present invention relates to a recording medium containing: a transparent sheet containing a substrate and an ink-receiving layer formed thereon; and a release film that is attached to a substrate-side surface of the transparent sheet and is to be stripped of after image recording, in which the release film contains: a release film main body; and an adhesive layer that is disposed facing the substrate-side surface of the transparent sheet and is to be removed together with the release film main body when the release film is stripped off after image recording, and the adhesive layer defines an adhesive-free non-attachment region which is continuously present along a recording medium-conveying direction during image recording.

  • Patent number: 4823082
    Abstract: A signal processing method in an electromagnetic induction test. A test object is subjected to an electromagnetic induction by use of N (N.gtoreq.1) kinds of test frequencies to obtain M (M.ltoreq.2N) kinds of phase detection outputs corresponding to respective states of the test object. The phase detection outputs are then sampled at a plurality of measuring points so that there exists n (n<M) kinds of disturbance factors of which a portion contribute to the electromagnetic induction test. The phase detection outputs have a variance greater than a variance of a target parameter of the test object and contribute to the electromagnetic induction test. A first coordinate axis Z, is determined in a direction in which a variance of a distribution of the group of the measuring points comes to be a maximum in an M-dimensional space formed with the coordinate axes associated with the M kinds of the phase detection outputs. The remaining coordinate axes are likewise determined.

  • Patent number: 4699007
    Abstract: A plurality of ultrasonic transducers or probes are positioned around a region of an object such as a steel tube to be inspected. One of the ultrasonic transducers is energized to emit an ultrasonic beam into the region, and ultrasonic waves reflected from and transmitted through the region in response to the emitted ultrasonic beam are received. Sound pressures are then measured from the reflected and transmitted ultrasonic waves, and an evaluation value is produced by arithmetically dividing the sound pressure of the reflected ultrasonic wave by the sound pressure of the transmitted ultrasonic wave.

  • Patent number: 4537073
    Abstract: For the inspection of a square billet, an ultrasonic testing technique using an angle beam is performed using a phased array system. The phased array probe is disposed in a plane perpendicular to the axial direction of a square billet, at a prescribed distance from the surface of the billet and set at a prescribed angle with respect to the billet surface. The billet is inspected both inside and at the surface layer when the ultrasonic beam is electronically scanned. Inspection of the surface layer only is also performed using a surface defect inspection apparatus. Determination of internal defects (including subsurface defects) is performed based on the subtraction of information from the surface defect inspection from the information from the ultrasonic inspection.

  • Patent number: RE33245
    Abstract: A method of measuring the temperature in a high pressure furnace of a hot isostatic pressing apparatus, wherein a closed-end pipe having its inside communicated with the inside of the high pressure furnace and enabling a pressure medium to pass therethrough is disposed in the furnace, an incident top end of an optical fiber, a bundle of optical fibers or like other equivalent optical rod-like memeber is disposed to the open end of the closed-end pipe so as to be capable of receiving thermally radiated light from the inside of the closed-ended pipe and an exit rear end thereof is led out through a cover and to the outside of said high pressure vessel and a measuring system is connected to said exit rear end to detect heat radiation power from the top end of the closed-end pipe to thereby measure the temperature inside of the furnace.
