Upon cleaning of crankcase gas generated during operation of an internal combustion engine in its crankcase, a centrifugal separator is used, which includes a rotor arranged for rotation by means of a driving motor and arranged by its rotation suck crankcase gas from the crankcase through a conduit to the centrifugal separator. During operation of the combustion engine a parameter, e.g. a measurement of the load on the combustion engine is sensed, the magnitude of said parameter being related to the amount of crankcase gas generated per unit of time in the crankcase. Depending upon a sensed change of the sensed parameter the rotational speed of the rotor of the centrifugal separator is changed in a way such that the gas pressure in the crankcase is maintained at a predetermined value, or within a predetermined pressure interval, during the operation of the combustion engine.

A filtration system is provided with filter media operable to remove solids, particulate and colloidal matter from a process fluid. Acoustic, vibration and sonic energy may be used to clean associated filter media to allow substantially continuous filtration of process fluids. The filtration system may be satisfactorily used with process fluids having a relatively high concentrations of solids, particulate and colloidal matter.

A cleaning method comprises: cleaning the liquid contact member by supplying a first liquid for cleaning to the liquid contact member; recovering the first liquid supplied to the liquid contact member; supplying a second liquid different from the first liquid to the liquid contact member after the liquid contact member is cleaned with the first liquid; recovering the second liquid supplied to the liquid contact member; and performing a process in which a concentration of the first liquid comprised in the recovered second liquid is set to a predetermined concentration or less.

The invention provides an air conditioner, which comprises a panel body, a panel and a panel opening mechanism, wherein the panel is arranged on the front side of the panel body; the panel opening mechanism is arranged on the panel body; the panel opening mechanism is connected with the panel in a driving way; the upper part of the panel opening mechanism is rotationally connected with the panel body; the lower part of the panel opening mechanism is clamped together with the panel body; and the panel opening mechanism is provided with a maintenance position which is clamped together with the panel body by being separated from the lower part of the panel opening mechanism, rotates around the upper part of the panel opening mechanism and is used for opening the lower part of the panel. According to the air conditioner, the upper part of the panel opening mechanism is rotationally connected with the panel body, the lower part of the panel opening mechanism is clamped together with the panel body, and the lower part of the panel opening mechanism can be separated from the panel body by slightly applying force outwards when cleaning or maintenance is required; and the panel and the panel opening mechanism can rotate together around the upper part of the panel opening mechanism, so that the panel is opened to the maintenance position, the panel is fixed effectively, and the panel can be opened conveniently to meet the requirement of maintenance or cleaning.

A new remover chemistry based on a choline compound, such as choline hydroxide, is provided in order to address problems related to removal of residues, modified photoresists, photoresists, and polymers such as organic anti-reflective coatings and gap-fill and sacrificial polymers from surfaces involved in dual damascene structures without damaging the dielectrics and substrates involved therein. An etch stop inorganic layer at the bottom of a dual damascene structure may or may not be used to cover the underlying interconnect of copper. If not used, a process step of removing that protective layer can be avoided through a timed etch of the via in trench-first dual damascene processes.

A dishwasher and a controlling method thereof are provided. The dishwasher includes a tub, a door, a steam generator, and a dish storage. The tub holds dishes and is opened at one end. The door selectively seals the opened end of the tub. The steam generator is provided outside the tub to generate steam. The steam discharger discharges the steam generated by the steam generator into the tub. The dish storage stores dishes to be sterilized by the steam discharged from the steam discharger.

An image forming apparatus includes an image bearing member, a toner image forming member, an intermediary transfer member for forming a primary transfer portion, and a primary transfer member supplied with a transfer voltage. The apparatus also has a voltage source for supplying, to the primary transfer member, a transfer voltage and a voltage of a polarity opposite to the transfer voltage, an image bearing member cleaning apparatus for removing toner from the image bearing member, a secondary transferring member, and an intermediary transfer member cleaning apparatus for electrostatically removing toner from the intermediary transfer member. The apparatus further has a voltage source control apparatus for controlling the voltage source so as to apply, to the primary transfer member, a voltage having an absolute value larger than a discharge threshold and having the polarity opposite to the transfer voltage, when a non-recording toner pattern passes through the primary transfer portion.
