Patent EP-0338610-A2 (EP)
Inventor: FRATTA ANTONINO DR ING
IPC: H02K19/06
Filed: 1989-04-03
Abstract: The synchronous reluctance machine has a rotor with axial magnetic segmentation comprising axial laminations (L) of a ferromagnetic material alternated with layers of a nonferromagnetic material, with permanent magnets (M) inserted in these layers at an orientation which produces a magnetic flux in the direction (q) of the quadrature axis and in a sense opposed to the magnetic flux produced by the quadrature components of the current in the stator. The permanent magnets (M) are proportioned so that the flux they produce is at least approximately equal in absolute value and opposed to the sense of the flux produced by the quadrature component of the nominal operating current flowing in the stator.

Abstract: The present invention provides methods for treating reclaimed sand obtained from dismantled foundry molds and cores which contain a cured binder derived from an ester cured alkaline phenolic resin. Treatment of the reclaimed sand with a silane solution, particularly an aqueous solution, enhances the tensile strengths of foundry molds and cores produced therefrom beyond those obtained with untreated reclaimed sand. Methods for producing foundry cores and molds which incorporate such a treatment process are also provided by this invention as are raw batch formulations.

Abstract: A compensating system for inspecting potentially warped printed circuit boards provides the inspection head of a printed circuit board inspection apparatus with a compensating device which is capable of detecting deviations in the printed circuit board which depart from a reference standard, for use in accurately compensating for such deviations during the board inspection procedure. An appropriate source (including ultra­sonic, laser and directed light sources) is used to direct emissions toward the surface of a printed circuit board to be inspected. Detected reflections are then used to provide infor­mation useful in determining deviations of the surface of the printed circuit board from the reference standard, to adjust the anticipated locations for any component features, connecting leads or pins which are to be inspected within the subject viewing field.

Abstract: Bei bekannten Modulationsstromregelungen wird häufig dem digitalen Nutzsignal ein niederfrequentes Pilotsignal überlagert und die sich im Lichtsignal ergebenden beiden Überlagerungsprodukte ausgewertet. Bei Laserdiodensendern mit Übertragungsgeschwindigkeiten von wenigstens einigen 100 Mbit/s muß wegen der Einschaltverzögerung der Laserdiode der Laserdiodenvorstrom so hoch eingestellt werden, daß sich nur ein Überlagerungsprodukt im Lichtausgangssignal ergibt, eine Regelung des Modulationsstroms in der bekannten Weise also nicht mehr möglich ist. Für die Modulationsstromregelung bei hohen Übertragungsgeschwindigkeiten wird erfindungsgemäß in das digitale Übertragungssignal periodisch wenigstens eine Impuls folge eingefügt oder eine im digitalen Übertragungssignal bereits enthaltene Impulsfolge ausgewertet, die wenigstens aus einem Teil mit überwiegenden Anteil logischer Einsimpulse und einem Teil mit überwiegenden Anteil logischer Nullimpulse besteht. <IMAGE>

Abstract: A cache controller (44) for cache memory (42) in accordance with this invention monitors main memory (60) accesses by a CPU (48) and determines whether read and write hits to occur. Upon a read hit, the cache controller (44) causes the CPU (48) to read from cache memory (42) and not from main memory (60). Upon a write hit, the cache controller (44) causes data from the CPU (48) to be written to cache memory (42) and not main memory (60). The cache controller (44) also snoops main memory (60) accesses by remote bus master devices to determine whether remote bus master snoop read and write hits occur. Upon a remote bus master snoop read hit, the cache controller (44) causes data in a cache memory location corresponding to an addressed main memory location to be written to the remote bus master device and not written from the addressed main memory location. Upon a remote bus master snoop write hit, the cache controller (44) causes data written from the remote bus master device to be written into a cache memory location corresponding to the addressed main memory location. If the remote bus master has control of the system bus, the controller (44) prevents the CPU (48) from performing a locked write instruction sequence. If the CPU is already executing the locked write instruction sequence, the remote bus master is denied control of the system bus.

Abstract: The present invention is directed to a heat shrink clad core optical conduit and to an optical conduit having either a thermoplastic, thermos et or liquid, light transmitting core surrounded by, preferably a fluoropolymer cladding which is in turn surrounded by a tight-fitting, finish polymer jacket which may be either transparent or translucent, and is preferably made of a polyvinyl chloride, polycarbonate, acrylic or silicone material. Numerous fillers and inserts maybe used in the finish jacket polymer and the finish jacket polymer may be formed into various shapes. Bondable jacket materials may be used. The preferred method of forming the manufacturing jacket around a heat shrinkable fluoropolymer cladding is by extruding a low extrusion temperature polymer over a heat shrink clad in its expanded form into which an increased interior pressure is maintained to prevent shrinkage during the extrusion process. The preferred method of forming the finish jacket around a base clad core material is by an extrusion process where the finish jacket material is extruded over a heat shrink type fluoropolymer clad, in its expanded form, cured thermoset core thereby simultaneously shrinking the clad.
