Title: A flow restriction detector for a nozzle assembly
Inventor: KELBRICK WILLIAM J
IPC: B08B9/032
Filed: 1995-08-18
Abstract: A flow restriction detector for a nozzle assembly of a liquid dispensing machine is capable of detecting a blocked or partially blocked nozzle during the cleaning of the nozzle assembly.  During nozzle cleaning, a return plate is attached to the nozzle plate of the nozzle assembly to receive a flow of pressurized fluid from the nozzles.  Both the inlet and return fluid lines are provided with pressure sensors, and the return line has a constant back pressure applied to it so that the differential between the inlet and return line pressure sensors is in the range 5-10 psi.  The pressure differential is monitored during cleaning and from one cleaning to the next for the purpose of identifying a blocked or partially blocked nozzle.  A change of as little as 5% from the pressure differential value established for an unblocked system may indicate a partial blockage of a nozzle.

Title: Method of manufacturing a multilayer solar cell
Inventor: WENHAM STUART ROSS
IPC: H01L31/076
Filed: 1995-12-01
Abstract: A semiconductor structure and method of forming the structure, where a supporting substrate or superstrate (12) provides the mechanical strength to support overlying thin active regions. The thin dielectric layer (11) deposited over the substrate or superstrate (12) serves to isolate the deposited layers from the substrate from optical, metallurgical and/or chemical perspectives. A seeding layer (13) is then deposited, the seeding layer being of n-type silicon with appropriate treatments to give the desired large grain size. This layer may be crystallized as it is deposited, or may be deposited in amorphous form and then crystallized with further processing. A stack of alternating polarity layers (14, 15, 16, 17) of amorphous silicon or silicon alloy incorporating n-type or p-type dopants in the alternating layers is then deposited over the seeding layer.      Solid phase crystallization is then performed to give the desired grain size of 3 µm or larger which can be achieved by extended heating of the layers at low temperature.
