Title: Lifting stacked flat objects from each other - involves blowing air through needle into gap between top sheets for easier removal
Inventor: LAPPALAINEN TEUVO
IPC: B65B43/18
Filed: 1990-09-26
Abstract: The stacked flat objects are lifted off from each other through vacuum grippers which pick up the topmost object which in turn is first perforated in order to produce at least one temporary open channel (12) which runs at least up to the depth of the boundary face (19) between the topmost object (10) and the one (11) underneath. Air is blown in through the channel (12) onto the boundary face (19) which becomes an air gap which separates the topmost object from the one (11) underneath and prevents the vacuum produced by the vacuum gripper from reaching the other objects lying below. The topmost object can be easily removed from the stack. Compressed air can be blown in between the top two objects through a cannula like needle (12). USE/ADVANTAGE - Easier single removal of the objects without breaks in the operation.

Patent DE-4136511-A1 (DE)
Inventor: RADERMACHER KLAUS
IPC: H01L21/36
Filed: 1991-11-06
Abstract: A process is disclosed for producing a silicon-iron silicide-heterostructure for electronic components. The object of the invention is to obtain a process that allows optoelectronic heterostructures composed of silicon and semiconductive FeSi2 to be produced so that silicon technology optoelectronic components may be integrated. For that purpose, high-energy Fe-ions are first implanted in the silicon substrate. This structure is then temper-hardened at a temperature above the transformation temperature of FeSi2 until a continuous layer made of metallic FeSi2 is created in the silicon substrate. Nuclei are then implanted in said layer. Finally, this Si/FeSi2-heterostructure is tempered below the transformation temperature. As result a continuous layer composed of semiconductive FeSi2 is obtained.

Title: Method of reducing contribution of unwanted photons to image produced by gamma ray imaging system
Inventor: BERLAD GIDEON
IPC: G01T1/164
Filed: 1992-06-09
Abstract: The method for recording fewer of the events that are caused either by Compton scatter photons or by gamma radiation interacting with lead involves locally determining the energy spectrum and fitting the determined energy spectrum with a trail function composed of a photopeak component of known energy shape, but unknown magnitude, and a Compton scatter component having a theoretically derived energy shape and an unknown magnitude for each pixel of the image.     The trial function is locally fitted to the measured energy spectrum to obtain the values of both the Compton Coefficient and the gamma radiation interacting with lead. The method enables removal of Compton contamination and also the contamination caused by interaction of the gamma photons with lead components.
