Abstract: A substrate treatment apparatus includes: a plurality of solution treatment modules stacked at multiple stages, each configured to perform a treatment using a treatment solution on a substrate; and a solution supply unit configured to supply the treatment solution to the plurality of solution treatment modules, wherein: the solution supply unit includes supply pipelines provided with a solution feeder corresponding to the solution treatment modules; and the solution feeder includes a pump configured to pressure-feed the treatment solution to the corresponding solution treatment module and a filter configured to filtrate the treatment solution, and is arranged adjacent to the corresponding solution treatment module in a horizontal direction.

Abstract: A golf club head cover (10) includes: a cover main body (11) formed so as to house a head (H) of a golf club, the cover main body (11) having an opening (11a) that allows a shaft (S) of the golf club to protrude outside in a state in which the head (H) is housed; a lid part (12) that opens and closes the opening (11a); and an attaching means (13, 14) for attaching a peripheral edge portion of the lid part (12) to a peripheral edge portion of the opening (11a) so as to bring the peripheral edge portion of the lid part (12) into close contact with the peripheral edge portion of the opening (11a), the attaching means (13, 14) being configured such that a close contact position of the peripheral edge portion of the lid part (12) with respect to the peripheral edge portion of the opening (11a) varies in accordance with the position of the shaft (S) protruding from the opening (11a).

Abstract: [Technical Problem] An object is to provide a golf club head cover and a holding tool for the same that are able to prevent the golf club head cover from being unintentionally released from a predetermined holding position. [Solution] The holding tool for a golf club head cover comprises: a first connector (10) disposed at a predetermined holding position for holding the head cover; a second connector (20) provided on the head cover, the second connector (20) being formed so as to be detachably fitted to the first connector (10); and an engaging part (13) provided on one connector (10) of the first connector (10) and the second connector (20), the engaging part (13) engaging with the other connector (20) of the first connector (10) and the second connector (20) when the connectors (10, 20) are fitted to each other, thereby to restrict movement of the other connector (20) in a direction opposite to the fitting direction.

Abstract: This optical connector holder includes a holder body into which optical connectors are inserted, connector housing recesses are formed on the holder body and caps which fit together with said optical ferrules of said optical connectors that are inserted into said connector housing recess and which cover their connection end faces, wherein said caps separate from said optical ferrules and remain on said holder body side when said optical connectors are withdrawn from said connector housing recesses.

Abstract: A holding member includes a flared tubular body and collectively holds a plurality of unused optical fibers provided with optical connectors within an optical distribution frame. The tubular body has a rectangular cross section and includes an elongated rectangular lower opening and an upper opening wider than the lower opening. A part of sidewalls of the tubular body is formed to serve as an openable cover. The cover is first opened; the optical fibers provided with the optical connectors are accommodated in the tubular body; and then the cover is closed.
