Negative plates cross-section

Fuji Peel-Apart Film FP-100. In 1984 Fuji introduced FP-lOO, a peel-apart instant color film rated at ISO 100. The FP-lOO system uses a dye-release process similar to that used in the Fuji integral films. Figure 16b is a schematic cross section of FP-100, and Figure 11b (on the colored plate) is a micrograph of the unprocessed film in cross section. The negative stmcture includes a spacer layer between the red-sensitive layer and the cyan dye-releaser layer that it controls, similar to that shown in the FI-800 stmcture, but there are no spacers between the other emulsions and corresponding dye-releaser layers. 

The flat supply air unit can be built of, for example, sheet metal as a box with one side perforated. The area of the perforated side must be slightly wider than the area to be protected since the acceleration of the plume (if colder supply air than the surrounding air is used) will cause the cross-section to be reduced. A uniform velocity profile is important to achieve the desired result divergences may result in negative effects to such a degree that the aim will not be reached. The use of a fabric felt filter downstream of the perforated plate to produce a more uniform velocity profile is therefore recommended. ... 

Under reverse bias (cathode positive, plate negative), the very few electrons that may escape the unheated plate will miss the wire, because the solid angle subtended is so small (or the scattering cross section is small), so the reverse-bias current is low, except at very high negative bias.

Accordingly, the lead sulfate develops evenly throughout the cross-section of the negative plate, as shown schematically in Fig. 17.6(a). 

The cells, fluid manifold plate and positive and negative terminals are sandwiched between upper and lower endplates which are linked by peripheral tie rods. The tie rods provide the compressive load to contain the structure. However, to ensure the load is distributed evenly over the complete cross-sectional area of the module, the upper endplate incorporates a sealed flexible bladder which is pressurized to 20.7-22.4 bar (2.07-2.24 MPa) with nitrogen gas. This ensures that electrical continuity is maintained within the cell module and prevents leakage of gases or liquids either within the module or to the surrounding atmosphere. Typical operating characteristics of the cell stack are...

Figure 11.7 A schematic cross section of a typical electron beam evaporator. The magnetic field poles and consequently the magnetic field is out of the plane of the drawing. The high negative potential of the filament assists in electron emission and establishes the electron energy and point of impact on the crucible. Generally electrostatic deflection plates are added to sweep the electron beam into and out of the plane of the drawing.
