Abstract: Tubular workpieces of oriented polymers such as polyethylene polyester and PVC are formed by drawing a workpiece over an expanding former in the absence of any force perpendicular to the axis of the workpiece. The processes do not require the use of any liquid lubricant. They enable greater degrees of expansion and hence orientation in the direction perpendicular to the axis to be achieved and result in products of improved appearance and strength.

Title: Self-aligning contact and interconnect structure
Inventor: GODINHO NORMAN
IPC: H01L21/28
Filed: 1991-01-11
Granted: 1996-01-02
Abstract: An MOS transistor for use in an integrated circuit, particularly CMOS integrated circuits, is fabricated with a self-aligning contact and interconnect structure which allows for higher packing density.     Self-aligning source and drain contacts overlap the gate but are prevented from short circuiting to the gate by oxide insulation between the source/drain contacts and the gate, and a layer of silicon nitride above the gate. Contacts to the gate are made on top of the gate over the active region of the transistor because the source and drain regions are protected by a hardened layer of photoresist during etching of insulation to expose the gate contact. Source, drain and gate contacts are protected by a layer of titanium silicide so that interconnects are not required to completely cover these areas.  Low resistance interconnects are formed of titanium silicide encapulated by a thin film of titanium nitride.

Abstract: An information processing apparatus includes an arithmetic operation executing unit, a memory unit, a memory control unit, a resource managing unit, and an execution designating unit.  The arithmetic operation executing unit executes an arithmetic operation on the basis of an instruction.  The memory unit stores the arithmetic operation result from the arithmetic operation executing unit.  The memory control unit has a buffer for temporarily storing data from the arithmetic operation executing unit and controls data transfer between the arithmetic operation executing unit and the memory unit.  The resource managing unit manages use states of resources of the arithmetic operation executing unit.  When an instruction is a data store instruction, the execution designating unit sends a buffer holding request to the memory control unit regardless of the resource state of the arithmetic operation executing unit.  When a buffer holding response is supplied from the memory control unit, the execution designating unit designates execution of the data store instruction to the arithmetic operation executing unit and the memory control unit on the basis of management information from the resource managing unit.

Filed: 1992-01-09
Granted: 2002-07-23
Abstract: A method of controlling the amount of a biologically active substance binding to a cell surface having both receptors to the substance and receptors for the Fc domain of an antibody that can complex with the substance or other antibodies that can complex with the substance. By exploiting the generally more numerous Fc receptor sites, substance binding can be increased and/or controlled. Method contemplates controlling amounts of substances such as cytokines, hormones, and growth factors that are associated with cells such as monocytes, macrophages, granulocytes, B cells, T cells, and platelets. Method is illustrated using conjugated antibodies to tissue necrosis factor (TNF) to increase the binding of TNF to monocytes.

Title: Reflective grain defect scanning
Inventor: MATTHEWS PETER CHARLES
IPC: G01N21/55
Filed: 1992-03-06
Granted: 1998-10-13
Abstract: Grain defect scanning is accomplished by a pair of light detectors directed toward an inspection point illuminated by a collimated light beam incident upon the inspection surface at a given angle of incidence.  one detector, the specular detector, is positioned along the specular angle of reflection as defined by the angle of incidence and the other detector, the diffuse detector, lies substantially along the angle of incidence.   When specular reflection dominates, as when the inspection point corresponds to clearwood,  the specular detector indicates a higher reflective light intensity than the diffuse detector.  When diffuse reflection dominates, however, as when the inspection point corresponds to a grain defect, both detectors indicate similar reflective light intensity.    Grain  defect  discrimination  is  accomplished  by calculating a ratio of specular detector output to diffuse detector output.   Further  analysis  of  the relative magnitudes  of the detector outputs provides a basis for identifying grading marks, such as ink and wax marks, at the inspection point.
