  • Publication number: 20240331846
    Abstract: A heart rate information concealed video transmission device includes a transmitter and a receiver. The transmitter compresses an input video and transmits the compressed video to a network, and the receiver decodes a received compressed stream, and attempts heart rate estimation by rPPG and generation of a biometric identifier. In order to invalidate heart rate estimation by a biological information processor, a corrected video generator outputs a corrected video in which small temporal variation of the input video is suppressed.

    Abstract: An aluminum wire, which is an electric wire of an electric motor of a compressor, is wound around a copper wire, which is another electric wire, at interval in the length direction. The portion around which the aluminum wire is wound is brazed with a brazing material containing a flux. Thus, the aluminum wire and the copper wire are joined together, and an electric wire joint section is formed. Insulating paper is mounted to the electric wire joint section. The inner surface of the insulating paper is brought into contact with the surface of the electric wire joint section to which a residue of the flux adheres.

  • Patent number: 8981614
    Abstract: Included are a pair of insulators arranged on axial end surfaces of a split core, and an insulating film attached to lateral side surfaces of the tooth part, for insulating the split core from a coil wound around the tooth part. Each insulator includes projections projecting further than a tooth front end part in the circumferential direction, slits which are formed in the respective projections to a corresponding axial end surface side of the tooth front end part and into which the insulating film is inserted, and ribs formed, on an end surface side in the circumferential direction, in the respective projections. The insulating film inserted into the slits is folded back to a back yoke part side with the ribs interposed therein, and fixed by being interposed between the ribs at tip portions of projections of adjacent insulators. Accordingly, the insulating film can be assuredly fixed and prevented from escaping from a slot.

  • Patent number: 7862758
    Abstract: An in-mold coating method for molding a molded product with an excellent external appearance. A resin molded product is kept pressed against a mold cavity surface until immediately before coating. Mold-clamping force in a second step in which the shape of the resin molded product is fixed and that in a fourth step are selected so that the deformation of the mold cavity by the mold-clamping forces is substantially the same in the second and fourth steps. Even if the mold cavity deforms by the mold-clamping force in the second step, the mold cavity deforms similarly in the fourth step to provide a uniform coating thickness. Alternatively, a mold-clamping force smaller than that in the first step is selected for the second step to reduce the degree of deformation of the mold cavity and to achieve a uniform coating thickness.

  • Patent number: 7790081
    Abstract: A process producing an in-mold coated molded product. The process molds a thermoplastic resin material under a mold-clamping pressure in a mold including a fixed mold part and a movable mold part each heated at a predetermined temperature, separates the fixed mold part and the movable mold part when the molded material surface is solidified such that it is durable to a pressure of injection and flow of a coating agent, and injects the coating agent containing a thermosetting resin material between an inner surface of the mold and the molded product obtained. The process also coats the molded product surface with the coating agent as the mold is re-clamped after injecting the coating agent, takes out the molded product coated with the coating agent when the coating agent is cured such that it is neither peeled off nor cracked by opening the mold, and re-heats the molded product after taking it out.
