    Abstract: A uniaxial eccentric screw pump enabling a stator to be easily separated into an outer cylinder and a lining member, and being capable of solving problems such as a positional shift and deformation of the lining member, and an occurrence of uneven wear and an unstable discharge amount associated with the positional shift and deformation. The stator includes a liner portion having a cylindrical shape and being integrally formed so as to have an inner peripheral surface of an internal thread type and an outer cylinder portion. The liner portion includes, at both end portions thereof, flange portions protruding radially outward, and an outer cylinder mounting portion is provided between the flange portions. The outer cylinder portion is mounted in a non-bonded state on the outer cylinder mounting portion, and both end portions of the outer cylinder portion abut on the flange portions, respectively.

    Abstract: A catheter comprises a tubular body portion (11) including an elongate portion (13) made of a transparent material, and at least one substantially linear contrast-radiography portion (14a, 14b) made of an X-ray opaque material and extending in the longitudinal direction of the elongate portion. The body portion (11) is hollow to allow passage of a liquid therethrough. A majority of the transparent material is composed of an aromatic polyurethane, while the material forming the at least one contrast-radiography portion (14a, 14b) is a mixture composed at least mainly of the X-ray opaque material and an aliphatic polyurethane.

    Abstract: A first cam mechanism 8 is provided between outer portions of opposite surfaces of a rotor 2 and a piston 3. A shaft portion 2c is integrally formed in a central portion of the opposite surface of the rotor 2 opposed to the piston 3. A pair of outwardly projecting portions 9a, 9a are formed in an outer peripheral surface of the shaft portion 2c. A through hole 3a in which the shaft portion 2c is inserted is formed in the piston 3. A pair of inwardly projecting portions 9b, 9b are formed in an inner peripheral surface of the through hole 3a. The outwardly projecting portions 9a, 9a are arranged such that each of the outwardly projecting portions 9a can pass through a gap between the inwardly projecting portions 9b, 9b and the inwardly projecting portions 9b, 9b are arranged such that each of the inwardly projecting portions 9b can pass through a gap between the outwardly projecting portions 9a, 9a. A second cam mechanism 9 is provided between opposite surfaces of the outwardly projecting portion 9a and the inwardly projecting portion 9b opposed to each other when the rotor 2 is rotated through a predetermined angle after the outwardly projecting portion 9a have passed through the gap between the inwardly projecting portions 9b, 9b.
