Abstract: A pin insertion hole penetrating an outer member from an outer circumferential side to an inner circumferential side is formed in the outer member. A pin groove that is concave from an outer circumferential side to an inner circumferential side is formed in an inner member. A positioning device includes a pin that is inserted into the pin insertion hole of the outer member and the pin groove of the inner member, a liner holder that comes in contact with a groove side surface of the pin groove, and a liner that is disposed between the liner holder and the pin in the pin groove.

Abstract: An UV-irradiation apparatus of an embodiment is provided with an irradiation unit, a measuring unit, a detecting unit, a calculator and a display. The irradiation unit irradiates treatment water as a treatment target with treating ultraviolet rays. The measuring unit measures ultraviolet ray intensity of ultraviolet rays transmitted through the treatment water. The detecting unit detects a deterioration of the irradiation unit in accordance with the ultraviolet ray intensity measured by the measuring unit. The calculator calculates the ultraviolet ray permeability of the treatment water, on the basis of the ultraviolet ray intensity of ultraviolet rays emitted from the irradiation unit depending on a preset setting value and the ultraviolet ray intensity measured by the measuring unit. The display displays the detection result of the deterioration of the irradiation unit by the detecting unit, and the ultraviolet ray permeability calculated by the calculator.

Abstract: A position adjustment device is provided with an eccentric pin and a push rod. The eccentric pin has a rotating shaft part, and an eccentric shaft part inserted into an end in a circumferential direction of a lower-half inside member. The push rod is inserted into the lower-half inside member from an end surface in the circumferential direction of the lower-half inside member, the push rod being able to come into contact with the eccentric shaft part within the lower-half inside member. The rotating shaft part has a columnar shape with a rotational axis line. The eccentric shaft part is formed with: a side peripheral surface that comes into contact with the inner peripheral surface of an eccentric shaft hole in the lower-half inside member into which the eccentric shaft part is inserted, and a rod contact surface that comes into contact with the push rod.
