  • Patent number: 11535685
    Abstract: A method of continuously producing an ethylene-vinyl acetate copolymer in a polymerization vessel containing a reaction liquid containing ethylene, vinyl acetate, a polymerization initiator and methanol, the polymerization vessel being connected via piping to a heat exchanger circulating a coolant, the method includes the steps of: supplying ethylene, the polymerization initiator and methanol to the polymerization vessel; introducing pressurized gas containing ethylene present in a gas phase portion of the polymerization vessel into the heat exchanger; supplying vinyl acetate cooled to between ?50° C. and 23° C. to an upper portion of the heat exchanger; flowing vinyl acetate down in the heat exchanger while absorbing ethylene; letting vinyl acetate dissolving ethylene out of a bottom portion of the heat exchanger and adding to the reaction liquid in the polymerization vessel; and taking the reaction liquid out of the polymerization vessel.

    Abstract: A breast image generating method correlates radiographing order information for instructing to radiograph each of left and right breasts of a subject in an oblique direction with identification information indicating a relationship between data of a breast image and the radiographing order information so as to be stored in a storing device. A breast is radiographed based on the radiographing order information to generate data of a breast image, radiographing order information corresponding to the generated data of a breast image is identified based on the identification information, and a stamp image is superposed at a prescribed position on the breast image taken through radiographing conducted in the oblique direction to make a composite image in accordance with whether a breast region indicated by the identified radiographing order information is left or right, so as to display the composite image on a displaying device.

  • Patent number: 5107515
    Abstract: Part of a laser beam, which is generated by a laser tube and reflected by a reflection surface of a high-reflectance mirror to travel while diverging at the predetermined angle, is divided by a dividing mirror. The spectral band width of the divided laser beam is narrowed by an etalon and a diffraction grating. The laser beam with the narrowed spectral band width is reflected by a high-reflectance return mirror, returned to the laser tube, and amplified in the laser tube. The laser beam with the narrowed spectral band width is amplified in substantially the same space within the laser tube where the laser beam was generated.
