The jaw plates can be used either on fixed or movable jaws, or both.

Abstract: An n-channel device (10) and a p-channel device (11) are formed from a single epitaxial silicon layer (60,61). During the deposition of the single epitaxial silicon layer (60,61), dopants are added to the epitaxial reaction chamber and subsequently changed to define a drain region (24,33), a channel region (27,34), and a source region (30,35). The dopant concentration is modified during the formation of the channel region (27,34) to create a doping profile (50). The doping profile (50) has a first profile (51) that is constant and a second profile (52) that changes.

Abstract: A workpiece support for a vise which is used for clamping a small workpiece on the vise and which can solve the problem that the prior art workpiece support has not versatility in clamping workpieces of various different configurations. In the workpiece support, a magnet is detachably mounted in a support plate and the support plate is fixedly attracted to a jaw plate of the vise through the magnet. Therefore, by forming a step in one side of the support plate along an edge and mounting the magnet in the support plate in a reversible manner, any one surface of the workpiece support can be selected as an attraction surface and the workpiece support can be used in many various forms depending on the workpiece configurations.

Abstract: There is provided a method and device for automatically aligning the proximal edges of two or more appreciably magnetic sheets to be connected along abutting edges. The device preferably includes supports to align the magnetic sheets in substantially planar relationship aligned relative one another with their proximal edges oriented in approximately abutting relationship and generally aligned along a predetermined contiguous seam line. At least one of the sheets is to remain moveable on the supports relative to the other sheets. The alignment device further preferably includes an electromagnetic mechanism for simultaneously creating an effective north pole along the proximal edge of one of the supported sheets, and an effective south pole along the confronting proximal edge of the other sheet. These opposing poles cause a magnetic attraction between the proximal edges of the sheets which automatically pulls and aligns the proximal edges into intimate contact along their length.

Abstract: A method of forming composite articles from components (12, 14, 16) is described in which the components are joined by adhesive at their interfaces (18). The components have cavities (22) and the adhesive is compressed while it sets by placing magnetically attractable particulate material (20) into the cavities on one side of the interface and placing magnets (26) on the other side of the interface so that the attraction between the magnets and the particulate material compresses the adhesive. The particulate material may be removed from the cavities after the adhesive has set through apertures (24).
