A processing system includes process modules, load lock modules, an equipment controller, and a machine controller. The equipment controller controls transfer and processing of wafers in the processing system. A transfer destination determining portion determines the transfer destination of each wafer such that each wafer is sequentially transferred to a normally operating process module. When an abnormality occurs in a process module, an evacuation portion temporarily evacuates to a cassette stage the wafer determined is to be transferred to the abnormal process module and that has not yet been transferred to the abnormal process module. When a new transfer destination of the evacuated wafer is determined, if a process that is performed immediately before processing the evacuated wafer in the processing module as the new transfer destination satisfies a predetermined condition, a transfer inhibition portion inhibits the transfer of the evacuated wafer to the new transfer destination.

The invention relates to a method of making a film, and to a die for making the film. The fluid die includes a fluid feed manifold connected to a housing having positioned therein at least one fluid feed channel in fluid communication with the fluid feed manifold. The housing also includes at least one profiling block within the fluid feed channel.

An additive manufacturing apparatus including a build chamber in which an object is built and a flow device. The flow device comprises a body having a Coand{hacek over (a)} surface and a passageway connectable to a pressurised gas source. The passageway has an opening located adjacent to the Coand{hacek over (a)} surface to, in use, direct a jet of gas over the Coand{hacek over (a)} surface. A space adjacent the Coand{hacek over (a)} surface is in fluid communication with the build chamber such that gas drawn into and / or propelled from the space causes gas flow through the build chamber.

An acoustic matching layer according to the present invention includes a powder of a dry gel. The dry gel preferably has a density of 500 kg / m3 or less and an average pore diameter of 100 nm or less. By using the dry gel powder, a variation in the property of the acoustic matching layer can be reduced.

An acoustic resistor for use in an audio device includes a resin film having air permeability in a thickness direction of the resin film, and the resin film is a non-porous film having through holes formed to extend straight through the resin film in the thickness direction. This acoustic resistor is used in an audio device including: a transducing part that performs conversion between sound and an electrical signal and that includes an acoustic element; a housing enclosing the transducing part and having at least one opening; and a passage for gas that is present inside the housing and communicates with the opening and in which the acoustic element is placed. The acoustic resistor is placed between the opening and the acoustic element in the passage. The variation in properties of the acoustic resistor of the present disclosure can be made smaller than that of conventional acoustic resistors.
