  • Publication number: 20210113170
    Abstract: This diagnostic image processing apparatus receives an input of an X-ray image of a hand or a foot, detects, in the X-ray image, the imaging range of the left hand, the right hand, the left foot, or the right foot, and extracts, at least for each joint located in the detected imaging range and used for assessment by using an assessment method selected from either van der Heijde method or Genant method, portions of relatively high luminance from the opposing ends of a pair of bones located across each of the joints. Then, the diagnostic image processing apparatus generates and outputs information about a distance and an area between the extracted high luminance parts as diagnosis information for each joint used for the assessment carried out by the selected assessment method.

  • Patent number: 10753503
    Abstract: A solenoid valve for a fuel system has an electric coil and an armature disposed in a housing. A preassembled valve unit with valve seat, valve member, valve spring, and armature plate connected captively to each other is provided. In the valve unit, the valve seat is loosely secured between valve member and armature plate. The valve unit is inserted and secured in an open housing end and the valve spring contacts an inner shoulder of the housing. Armature plate and armature form a magnetic circuit. The valve member is supported on the armature plate and switched to open and close an outlet of the valve seat. By suppling current, a magnetic field is generated in the armature and attracts the armature plate into an operative valve position. The valve spring returns the armature plate into a rest position when the coil is currentless.

  • Publication number: 20200072162
    Abstract: An attachment structure for a solenoid valve which can be stably attached to and removed from a carburetor unit with a single movement and without increasing the number of parts. A rod-like supporting portion is disposed a predetermined distance away from a surface of a carburetor unit and extending in a direction substantially perpendicular to a direction of and installed near an opening in the surface of the carburetor unit. A cylindrical engaging portion extends from a circumferential face of a cylindrical body fitted on the solenoid valve substantially perpendicular to an axial line of the rod-like supporting portion, and forms a groove-like engagement portion which is narrower in diameter than the rod-like supporting portion, whereby the engaging portion, via the groove-like engagement portion, is coupled to and supported by rod-like supporting portion when an insertion portion of the solenoid valve is inserted into the opening.

  • Publication number: 20190052774
    Abstract: An image processing apparatus includes an acquisition unit that acquires information about a color space specified for an object to be processed by interpreting input image data, and a determination unit that determines whether a first color conversion or a second color conversion is used by using the information acquired by the acquisition unit. The first color conversion is used for converting only a color to be processed into a color in a device-dependent color space. The second color conversion is used for converting the color to be processed and the color having a different density into a color in the device-dependent color space.

  • Patent number: 10145346
    Abstract: An electromagnetic fuel valve has a valve chamber, a valve element and a valve seat assigned to the valve element. The valve chamber is delimited by an electromagnetic drive which moves the valve element relative to the valve seat. The drive includes a receiving housing for a coil carrier with an electrical coil. A magnet core is inserted into the coil carrier and has an end section facing the valve element. At an open sealing end facing toward the valve chamber, a sealing element is arranged between the end section of the magnet core and the receiving housing. To achieve good sealing, that end section of the magnet core situated in the sealing element expands the sealing element and compresses the material thereof radially against the edge of the sealing end of the receiving housing to seal the valve chamber to the interior space of the receiving housing.
