Abstract: Provided herein is an arrangement for a dishwasher for creating a wash zone with a selectable position within a washing chamber of the dishwasher. The arrangement may include a water spray arm rotatably arranged around an axis in the washing chamber, and a support element arranged to support the spray arm in the washing chamber. The support element may lock the spray arm in at least one position within the washing chamber. The arrangement may include a control unit arranged to control the operation of the dishwasher and a user interface for selecting the desired wash zone position within the washing chamber, and arranged to communicate the information to the control unit. The control unit may lock the support element in the selected position to create the wash zone. A dishwasher that includes the arrangement and a method for creating a wash zone with a selectable position are provided.

Abstract: Apparatus for cleaning a window of a vehicle is provided. The apparatus includes: a fluid extraction opening provided on the vehicle in proximity to the window of the vehicle; a suction pump mounted in the vehicle; and a fluid tight conduit extending between the fluid extraction opening and the suction pump.

Abstract: Disclosed are an apparatus for treating a substrate and a method of treating substrates. The apparatus includes an inlet valve through which a supercritical fluid flows into the process chamber until an inner pressure of the process chamber reaches a first pressure and a turbulent flow generator turbulently supplementing the supercritical fluid into the process chamber until the inner pressure of the process chamber is recovered to the first pressure. A pressure drop module partially removes a supercritical mixture from the process chamber until the inner pressure of the process chamber is dropped to the second pressure. A pressure drop mode and a supplemental mode may be alternately repeated by the flow controller.

Abstract: A liquid chemical for forming a water repellent protecting film on a wafer having at its surface an uneven pattern and containing at least one kind of element selected from the group consisting of titanium, tungsten, aluminum, copper, tin, tantalum and ruthenium at surfaces of recessed portions of the uneven pattern, the water repellent protecting film being formed at least on the surfaces of the recessed portions. The liquid chemical is characterized by including: a water repellent protecting film forming agent; and water, and characterized in that the water repellent protecting film forming agent is at least one selected from compounds represented by the following general formula [1] and salt compounds thereof and that the concentration of the water relative to the total quantity of a solvent contained in the liquid chemical is not smaller than 50 mass %.

Abstract: A cleaning device is provided that includes a cleaning element, a cleaning head, a housing, an electric pump, a battery, a container of cleaning fluid, an activation button, and a spray nozzle. The cleaning element and the cleaning head have spray openings that are in registration with one another. The container forms a fluid and air tight connection with the pump. The activation button places the pump and the battery in electrical communication. The spray nozzle forms a fluid tight and air tight connection with the pump so that the pump is configured to spray fluid from the container through the first and second spray openings onto a surface to be cleaned. The cleaning head, the cleaning element, and the spray nozzle define a cavity that traps spray from the spray nozzle between the cleaning device and the surface to be cleaned.
