Systems and methods are provided in which residual materials are removed from an interior surface of a drum or similar vessel at the end of a duty cycle. This is followed by application of a non-siliceous aqueous solution to the cleaned surface, which provides a durable low-friction coating to the interior wall of the rotating drum mixer throughout the following duty cycle or use.

Contaminant is prevented from migrating from a gripping hand and contaminating a substrate case after cleaning the substrate case. The apparatus cleans, in a state with no substrate, a substrate case C which holds a substrate, provided with a booth 10 which forms a clean space, provided with cleaning tanks 40, 50 which hold and clean the parts of the substrate case C in a separated status in the booth 10, provided with a conveyance mechanism 60 which grips part of the substrate case C by a gripping hand 70 and conveys them to and from the cleaning tanks 40, 50, making the gripping hand 70 stand by at a standby position Q in the booth 10 during cleaning of the substrate case C, and provided with a cleaning means 80 for cleaning the gripping hand 70 during cleaning of the parts. The cleaning means 80 is provided with a spray nozzle 81 which sprays a gas toward the gripping hand 70 and an exhaust fan 82 which exhausts the gas from the inside of the booth 10.

A container cleaning device includes a mounting plate shaped for accommodating a wafer; and a nozzle assembly disposed on the mounting plate and including a base and a shell complimentarily disposed on the base. The shell includes an inlet and at least one outlet member disposed on an edge. The base includes a recess communicating with the inlet, and at least one outlet element each being inclined at a predetermined angle with respect to the shell. Each outlet member of the shell is adjacent to and communicates with the corresponding outlet element of the base.

The invention concerns a device and a method of remotely controlling a motorized submerged surface cleaning apparatus (1) comprising a body and a drive device, said remote control device comprising a control terminal (15) having a housing, a device (16) for transmitting control signals for the drive device, characterized in that the housing comprises an orientation detector furnishing at least one orientation parameter of the housing, and in that said device comprises a unit for processing orientation parameters, producing a first command for the drive device for an orientation parameter that is within a first interval of values, and a second command for the drive device for an orientation parameter that is within a second predetermined interval of values.

The present invention provides a metal cavity inwall decoking method, comprising: a. Process sealed compression to the metal cavity; b. Process rapid decompression to the metal cavity.

The present invention makes such substance as hydrocarbon volatiles, moisture and so on inside the coke gasify quickly because of fierce change of pressure differential by compressing and then decompressing the metal cavity rapidly, which makes the coke crush and fall off from the inwall of metal cavity and finally finish the decoking work. The decoking method claimed in the present invention is simply and convenient to operate, and can greatly increase the decoking efficiency.
