摘要:
The present invention relates to a blind rivet nut. Blind rivet nuts are used to connect items to surfaces of materials, such as roof racks to automobiles, and have proven to be extremely reliable. However, difficulties occur when attempting to connect to several layers of materials or when material thickness increase, as it has been necessary to increase hole size in order to ensure hole registration and this can cause sealing problems. The invention provides a blind rivet nut capable of being used through one or several layers with improved grip capability and improved sealing ability preventing ingress of moisture. Lines of weakness in the form of grooves are formed in a portion of the body of the blind rivet nut so that material deforms selectively thereby improving the grip of the blind rivet nut. A flange has an annular recess that enables an O-ring seal to deform more efficiently, giving a larger ‘footprint’ than was previously possible thereby enhancing sealing.

The invention relates to a blind rivet, related method of removal and a tool. The removable blind rivet has a rivet body that receives a mandrel. The rivet body has a flange with a line of weakness formed therein. The line of weakness is adapted to shear under an axial load, whereby the flange is severed, substantially as a single item, from the rivet body. The invention extends to a tool for removing the rivet, the tool having: a body and a punch surface, the punch surface adapted to apply an axial force to a region of the flange, whereby the flange is severed from the rivet body in the form of an annulus, leaving a hollow rivet body that may be removed from a workpiece. The advantage of the invention is that it enables the flange to be removed form the rivet body as a single item.

A method of forming transistors with close proximity stressors to channel regions of the transistors is provided. The method includes forming a first transistor, in a first region of a substrate, having a gate stack on top of the first region of the substrate and a set of spacers adjacent to sidewalls of the gate stack, the first region including a source and drain region of the first transistor; forming a second transistor, in a second region of the substrate, having a gate stack on top of the second region of the substrate and a set of spacers adjacent to sidewalls of the gate stack, the second region including a source and drain region of the second transistor; covering the first transistor with a photo-resist mask without covering the second transistor; creating recesses in the source and drain regions of the second transistor; and forming stressors in the recesses.

The present invention relates to the significant functional role of several C. elegans genes and of their corresponding gene products in cell cycle progression during cell division that could be identified by means of RNA-mediated interference (RNAi) and to the identification and isolation of functional orthologs of said genes including all biologically functional derivatives thereof. The invention further relates to the use of said genes and gene products (including said orthologs) in the development or isolation of anti-proliferative agents, particularly their use in appropriate screening assays, and their use for diagnosis and treatment of proliferative and other diseases. In particular, the invention relates to the use of small interfering RNAs derived from said genes for the treatment of proliferative diseases.

Iridescent magnetic pigments are produced by depositing a ferrite layer and a second metal oxide layer in succession on a substrate. The substrate may be platy and is coated with the ferrite, which is then coated with the second metal oxide layer to provide interference color effect. At least one of the layers is magnetic. The magnetic pigment may be used in coatings such as paints.

The present invention relates to a blind rivet and blind rivet removal system and related method. Once set the blind rivet is not normally removed. However, increasingly removal is required due to the need to recycle automobiles. In order to remove blind rivets it has been necessary to remove the rivet flange by a variety of methods. Generally these methods were ineffective due to the resistance afforded by the mandrel and the risk of damage to the application or workpiece. Removing this unwanted swarf and debris often proved difficult. The invention provides a rivet with a stepped flange and a rivet removal tool with clips adapted to fit between the flange and surface of a workpiece so that upon relative displacement of the clips a rivet is extracted in a substantially axial direction as a single item. The invention also includes a tool and related method of blind rivet removal.
