Abstract: A device (1) whereby a pile (4) of rectangular items (7) is placed on an inclined surface (14) and pushed towards the straight front edge (20) thereof by a push unit (30). The surface (14) presents two pairs of conveyor belts (58, 58') parallel to each other and coplanar with the surface (14); and the pile (4) is arrested upon a bottom portion (17a, 17b) of the first item (7) in the pile (4) activating a first or second limit stop sensor (27a, 27b), which activates a respective pair of belts (58, 58') so as to move the bottom left or right portion (17a, 17b) of the item (7) and so orient the item (7) in relation to a gripping plane (P). A gripping unit (70) with two suction cups (103) movable along a three-dimensional trajectory grips the oriented item (7) and feeds it to a follow-up conveyor belt (75).

Abstract: An embodiment of the present invention is a switching power supply that includes a full-wave bridge rectifier to rectify incoming AC line voltage, a transformer having a primary winding and two secondary windings and a switched mode power supply chip that includes an integrated high voltage power MOSFET with a low voltage tap in the drift region. The MOSFET controls power switching of the primary winding of the transformer and has a high voltage present during initial power-up. This high voltage is dropped across the JFET part of the MOSFET and supplies a safe operating area protection circuit with a low voltage signal that will shut-off the MOSFET if the current passing through the MOSFET produces a voltage drop at the tap that exceeds a predetermined maximum.

Abstract: This invention relates to an improved solid state suppressor, such as a bidirectional thyristor structure, and a method for making the same. Due to the fact that at least part of the substrate is substituted with a material of a second conductivity type, thus forming a deep anode (22,22') or cathode (52), it is possible to produce a suppressor having a substrate which has an effective thickness that is less than the physical thickness of the slice. This allows for a good functioning suppressor which is unlikely to break during fabrication.

Abstract: An optical subassembly is disclosed which provides for passive alignment between an active optical device, lens and optical fiber. A first substrate is used as a mount for the active optical device and a second substrate is formed to include an aperture designed to capture the lens. Alignment fiducials formed on the mating surfaces of the first and second substrates provide accurate optical alignment between the active device and the lens. An optical fiber receptacle is formed to mate with the optical header supporting the substrates and thus provide alignment between the optical fiber and the active device/lens configuration. Preferably, the receptacle is formed to prevent physical contact with the aligned substrates, so that any movement of the receptacle will not effect the alignment between the device and lens.

Abstract: In a passive optical COUPLE ATM network, sampling times are obtained which cannot be accurately defined in time due to delay differences. It is therefore the object to find the exact phase angle of each data packet. For this purpose, the header of the packets is in each case sampled continuously and staggered in time, the staggering corresponding to the time "bit duration/N different samplers" (N = number of). The samples are read in parallel with one another into N shift registers (33.0 - 33.7). The content of the shift registers which is being built up during this process is checked at the bit rate of the packets for whether it corresponds to a predetermined keyword (S) or not. The resultant check bits (P) are stored for the duration of one clock interval. The in each case current check bits and the stored check bits are jointly used for determining the centre of the agreements found. The serial output (43.0 - 43.7) of the shift register (33.0 - 33.7) which corresponds to the respective centre then supplies the samples of the respective packet. <IMAGE>

Abstract: Disclosed is a method of planarizing the surface of a silicon wafer in integrated circuit manufacture where trench isolation techniques are employed. The trenches (20-23) and active areas (31-34) on a semiconductor substrate (10) are conformally coated with a layer (15) of silicon oxide. A layer of patterned polysilicon then is deposited on top of the oxide and etched to create filler blocks (30) in depressions above the trenches. Next, the polysilicon is annealed to thereby fill the trenches with an expanded oxide block. The resulting relatively planar surface then is polished back to the nitride cap, to thereby produce a high degree of planarity across all trench and active area dimensions.

Abstract: An optical system (10) for providing low and high resolution images of a patterned wafer (11) to provide for film thickness measurements thereof. The optical system (10) comprises a spectrally filtered light source (18) for providing light to illuminate the wafer (11). A low resolution imaging system (34) is provided for imaging the wafer (11) at a relatively low resolution. A high resolution imaging system (37) is provided for imaging a subarea of the wafer (11) at a relatively high resolution to create an enlarged image in the same object plane as the wafer (11). An image producing system (35) is provided for producing a visual image of the wafer (11) derived from the low and high resolution images. The high resolution imaging system (37) uses subaperture optical elements, comprising either a small scanning lens or a sparse array of lenses, to image small areas of the wafer (11) at higher resolution, and the subaperture optical elements (37) create an enlarged image in the same object plane as the actual wafer (11). Both areas are then imaged onto the image producing system (35) such as a CCD array (35) of a CCD camera (35a), by the low resolution imaging system (34) (a lens or reflector) to provide a common or cofocal feature of the present invention. This arrangement avoids frequent refocussing to make thickness measurements on different parts of the wafer (11). The present invention allows the determination of thin film thicknesses of patterned wafers (11), planar wafers (11), and silicon-on-insulator (SOI) wafers (11), even though the spatial frequencies of the patterns are radically different in all these cases. The present invention provides the ability to make thickness maps of magnified regions within a semiconductor chip as well as test pads located in scribe alleys thereon. The use of high resolution multispectral subimages significantly increases the speed at which thickness maps of these patterned regions are generated. The invention may also be used to measure the that also allows determination of position and orientation of the wafer (11) since the wafer edges are in focus.
