    摘要： A head cleaning device includes a first wiping member, a first drive mechanism, a second wiping member, a second drive mechanism, a common drive source, and control circuitry. The first wiping member wipes a nozzle face of each of a plurality of liquid discharge heads. The first drive mechanism moves the first wiping member to a first wiping position at which the first wiping member wipes the nozzle face and a first retraction position spaced apart from the nozzle face. The second wiping member wipes the nozzle face. The second drive mechanism moves the second wiping member to a second wiping position at which the second wiping member wipes the nozzle face and a second retraction position spaced apart from the nozzle face. The common drive source drives the first drive mechanism and the second drive mechanism. The control circuitry controls the common drive source.

    摘要： [Problem] To provide a reducing agent supply apparatus that can quickly melt urea aqueous solution solidified in a reducing agent injection valve to allow early start of the injection control of urea aqueous solution, a method for controlling the reducing agent supply apparatus, and an exhaust gas purification apparatus.[Means for Resolution] A reducing agent supply apparatus, including: a storage tank for storing liquid reducing agent; a pump for pumping the reducing agent; a reducing agent injection valve for injecting the reducing agent pumped by the pump in an exhaust pipe of an internal combustion engine; and a reducing agent passage connecting the pump to the reducing agent injection valve, wherein, when the internal combustion engine stops, a purge process of collecting the reducing agent in the reducing agent passage into the storage tank is performed, and wherein, on part of the reducing agent passage, a siphon function portion is provided for, even when, at the start of the internal combustion engine, the reducing agent injection valve is in injection failure due to solidification of the reducing agent in the reducing agent injection valve, causing some of the reducing agent to reach the reducing agent injection valve after the start of the pump to cause the solidified reducing agent to melt.

    摘要： [Problems] To provide a multilayered structure which eliminates the need of providing any particular adhesive layer, enables the ethylene/vinyl alcohol copolymer to exhibit excellent oxygen-barrier property to a sufficient degree, and can be effectively used even when a polyolefin resin is used as the inner and outer layers.[Means for Solution] A multilayered structure having an adhesive intermediate layer of a blend of an ethylene/vinyl alcohol copolymer (A) and a maleic anhydride-modified olefin resin (B) between an inner layer and an outer layer, the adhesive intermediate layer containing the ethylene/vinyl alcohol copolymer (A) and the maleic anhydride-modified olefin resin (B) at a weight ratio of 4:6 to 8:2, the phase structure of the adhesive intermediate layer being a sea-island structure with the maleic anhydride-modified olefin resin (B) as the sea or being a bicontinuous phase, and the adhesive intermediate layer having a standard deviation of not less than 65 when a contrast profile of the ethylene/vinyl alcohol copolymer (A) and the maleic anhydride-modified olefin resin (B) in the adhesive intermediate layer near the interface thereof is numerically expressed on a scanning electron microphotograph of the cross section of the multilayered structure in the direction of thickness by using an image analysis software.
