The present invention relates to a technique for producing a jointed member by subjecting two to-be-jointed members which are contacted each other to friction stir welding. The method for producing a jointed member executes a dwelling step in which a probe is rotated only for a predetermined period at at least one of a probe starting point position which is a position of the probe for forming a joint starting point in the to-be-jointed member and a probe end point position which is a position of the probe for forming a joint end point in the to-be-jointed member.

An ink cartridge includes a storage portion, a housing, a movable member, a support portion, and an intermediate member. The storage portion has flexibility and is configured to store ink. The housing that covers the storage portion and at least a central portion of the storage portion is fixed to the housing. The movable member contacts with the storage portion in the housing, and is rotatable in accordance with changes in a position of contact with the storage portion. The support portion is provided in the housing and includes a pair of engagement portions. The pair of engagement portions are disposed at an interval therebetween and rotatably support the movable member. The intermediate member is disposed between the movable member and the storage portion.

A brazing sheet of aluminum alloy composed of a core material and a first brazing filler metal covering one surface of the core material. The core material contains as an essential component 0.2-1.0 mass % of Cu and as optional components at least one species of no more than 1.5 mass % of Si, no more than 1.8 mass % of Mn, no more than 0.35 mass % of Ti, and no more than 0.5 mass % of Mg, with the remainder being Al and inevitable impurities. The first brazing filler metal has a liquid phase ratio (X %) at 600° C. and a thickness (Y μm) such that X and Y satisfy the following relationship: (1) 30≦X≦80, (2) Y≧25, and (3) 1000≦X×Y≦24000. The brazing sheet provides good brazeability and maintains high corrosion resistance after brazing on the surface cladded with the brazing filler metal.

Providing liquid treatment equipment capable of largely reducing a frequency of discarding a treatment solution as a whole and capable of implementing smooth and high quality liquid treatment with less manufacturing burden. Equipment comprises a treatment solution bath capable of accommodating a treatment solution for implementing liquid treatment to a substrate to treat, a treatment solution circulating system circulating the accommodated treatment solution between the outside of the treatment solution bath, and a product removal unit removing a reaction product due to the liquid treatment contained in the circulated treatment solution. By circulating the accommodated treatment solution between the outside of the treatment solution bath, reaction products contained in the circulated treatment solution are removed by means of the product removal unit. Thereby, a chemical change substance and a decomposition product remaining in a treatment solution can be removed, resulting in preventing a treatment solution from deteriorating.
