Title: A checking and controlling apparatus for use in capsule-packaging machines
Inventor: TREBBI ROBERTO
IPC: A61J3/07
Filed: 1999-11-02
Granted: 2001-02-21
Abstract: The thrusters (6) or the rams for pressing the metered amounts of product into the metering seats are equipped with force transducers (T) which emit an electrical signal proportional to the thrust exerted during the said pressing step and this signal is transmitted to the processor (39) for controlling the operation of the packaging machine, which compares the signal with predefined reference values, in order to check whether or not the weight of the metered amounts lies within acceptable values. If it does not, the processor causes expulsion, from the unloading flow the full capsules, of those capsules with metered amounts which have an unacceptable weight and which, if necessary, may be weighted using precision means (49) connected to the processor which may use this signal to confirm the operation of the said transducers or correct it automatically. All the capsules produced by the packaging machine and checked one-by-one for their weight then undergo a statistical check as to the weight itself using precision means connected to the processor which, also on the basis of the signals supplied by the said force transducers, if the packaging machine is provided with means for automatically adjusting the metering seats and the heightwise position of the pressing thrusters or rams, causes activation of these adjusting means so as to ensure that the metering devices produce metered amounts of product with an acceptable weight. Force transducers are also associated with the thrusters or rams for discharging the metered amounts of product from the metering devices, and the associated signals produced are transmitted to the processor which records them and can use them, if necessary, to perform processing of the signals produced by the force transducers associated with the said pressing thrusters or rams.

Abstract: This invention provides etching process for multi-layer structure in semiconductor device. It involves the formation of multi-layer structure on silicon substrate. Groove pattern is produced through the application of processes of photolithography, etching ... etc., and trench is formed through the application of processes of oxidation, deposition, dry etching ... etc. Deposition of undoped and doped polysilicon is performed sequentially to create composite polysilicon structure whose surface is then planarized using chemical mechanical polishing. Uniform oxide layer is formed on the surface of the composite polysilicon structure using blanket implantation and oxidation method. Finally, the multi-layer structure outside the trench is removed by wet etching and dry etching. This process has the advantages of being low cost and easy for production because it employs less dry etching processes and substitutes when using wet etching processes as well.
