  • Publication number: 20220017257
    Abstract: A can body has a curl portion to which a skirt portion of a cap is mounted. In the curl portion, an outer periphery upper-side bent portion that forms an outer peripheral portion of a folded-back top portion, an outer periphery-side tubular portion that extends downward in a can axis direction, an outer periphery lower-side bent portion that is bent inward in a radial direction, and a curl end portion that extends from an inner peripheral edge of the outer periphery lower-side bent portion are continuously formed. When a radius of curvature of an outer surface of the outer periphery upper-side bent portion is R5 (mm), a radius of curvature of an outer surface of the outer periphery lower-side bent portion is R6 (mm), and a radius of curvature of an outer surface of the inflection portion is R7 (mm), which is 0.05 to 0.2 mm, R7<R6<R5 is established.

  • Publication number: 20150141822
    Abstract: A method for generating a region of interest (ROI) wherein in setting ROIs in biological tissues to be compared, burden on a subject can be reduced and the reproducibility of elasticity measurement improved, including: setting candidate points in an arbitrary designated region in a notable tissue in a contrast image of an object designated by an input device; determining partial differential values of pixel values in a two-dimensional direction in the contrast image and thus detecting a tissue boundary; acquiring a shortest distance between the detected tissue boundary and each point, and setting a circle or polygonal region inscribed in the circle having the maximum shortest distance as a radius around the candidate point having the maximum shortest distance as a region of interest; and imaging the region of interest and superimposing it on the contrast image and displaying it on an image display unit.

  • Patent number: 8485976
    Abstract: Even when a region of interest (ROI) is changed on a frozen image, an elasticity image of ROI after the change can be displayed without executing re-measurement. An ultrasonic diagnostic apparatus 1 has a control unit 110 having a first ROI setting unit 38 and a second ROI setting unit 39. When ROI is set by the first ROI setting unit 38 of the control unit 110, an elasticity information calculating unit 32 sets an area larger than ROI as a calculation area, calculates distortion, elasticity modulus, etc. of a tissue corresponding to each measurement point on a tomographic image of the calculation area, generates elasticity information based on the distortion, the elasticity modulus, etc., and outputs the elasticity information to an elasticity information storing unit 33. The control unit 110 changes the position/size of ROI by the second ROI setting unit 39 under a state that the frozen image is displayed.

  • Patent number: 4516078
    Abstract: A variable frequency passband circuit comprising two passband filters and three mixers (front, intermediate and output mixers) connected in a cascade fashion disposed in a signal path. Two VCOs inject frequency signals into the front mixer and the output mixer. The two VCOs are respectively controlled by control signals at two potentiometers through transfer switching means so that the synthetic passband of the filter may be varied. One potentiometer suppresses the higher frequency region of a baseband signal and the other potentiometer suppresses the lower frequency region of the base band signal, irrespective of USB or LSB receiving mode.
