Title: Processor-controlled drive apparatus for a semiconductor-wire bonder and method of operating same
Inventor: BILANE GLEN BRADLEY
IPC: H01L21/60
Filed: 1979-11-20
Abstract: An apparatus for bonding wires onto semiconductor is provided with a processor controlled vertical drive mechanism (26,27,28) coupled to a bonding head of the type having a bonding tool (21) mounted therein. Known numerical control arrangements for tools are too slow for such bonding operations. In this apparatus height of the bonding tool (21) at a reset position and at a bonding position is programmed into the processor for each bonding operation on a semiconductor device of workpiece, the processor learning from the first operation. Sensing contacts (56,59) are provided on the bonding head for establishing and sensing the reset position and the bonding positions. The processor is programmed to compute intermediate positions between said predetermined vertical positions to obtain optimum high speed movement of the bonding head and the bonding tool (21) during subsequent bonding cycles.

Filed: 1979-09-17
Abstract: The invention adjusts the stroke depth of the ram (6) by permitting a modification of the position of the stops (3) without having to raise the block (4) from the part being shaped. The stops (3) are temporarily unloaded there by a thrust opposite to that of the block (4) - the counterthrust being obtained for example by double action cylinders (2) - without releasing the pressure on the part being shaped. This permits a fine adjustment to the stroke depth in a single operation. The method is applicable to bending presses comprising mechanical means (3) for stroke limiting as well as those comprising hydraulic means for stroke limiting. <IMAGE>

Patent EP-0018130-A1 (EP)
Inventor: DURHAM ROBERT L
IPC: A01G5/06
Filed: 1980-04-01
Abstract: A composition which forms a firm, bound aggregate-water support for floral arrangements with 60%-80% by weight water. The composition comprises a water-insoluble, water-retaining binder, such as a particulate, water-insoluble, water-swellable, cross-linked polymer, and inert non-packing, highly porous water-trapping, aggregate particles dispersed throughout, the particles being present in an amount and having a bulk density and surface area effective to disperse the composition through-out the water as the composition is added to it without hand kneading or stirring. Only sufficient binder, 0.1% to 5.0% by weight, is present to firmly bind the aggregate particles together. Rice hull ash is prefered as the aggregate and the preferred binder is acrylonitrile-starch graft copolymer. The composition can be added to water in a container of any size or shape in an amount sufficient to form the bound aggregate and the composition sinks in and disperses throughout the water and forms a support without the need for mixing with a mixer or kneading with the hands. The aggregate-water support is also used for rooting of some plants and transporting cut flowers.

Abstract: Compositions comprising 1-99 parts by weight of crystalline polyolefin resin and correspondingly 99-1 parts weight of polynorbornene per 100 total parts by weight of resin and polynorbornene and enough plasticizer to reduce the glass transition temperature of the polynorbornene to within the rubbery range, typically between 30-400 parts by weight of polynorbornene plasticizer per 100 parts by weight of polynorbornene, are moldable thermoplastic compositions exhibiting improved strength, greater toughness or impact resistance than the components of the blend. Compositions comprising more than 80 parts by weight of crystalline polyolefin resin per 100 parts by weight of polyolefin resin and polynorbornene combined are thermoplastic compositions exhibiting improved impact resinstance. Compositions comprising less than 80 parts by weight of crystalline polyolefin resin are elastoplastic, i.e.,they exhibit elastomeric properties yet are processable as thermoplastics. In preferred compositions of the invention the polynorbornene is cross-linked and is dispersed throughout the polyolefin resin as discrete particles having a size 50 microns number average or below. A preferred process for the production of the compositions of the invention in which the polynorbornene is cross-linked comprises masticating a blend of polyolefin resin and polynorbornene with rubber curative at cross-linking temperature until the polynorbornene is cross-linked.

Abstract: A process is described, which is employed especially for the sterilisation and disposal of contagious materials such as arise for example in connection with the most widely varying hospital waste, but also in the form of contagiously effected foodstuffs or similar goods. In this case, the process includes a vacuum steam sterilisation in which the materials, where these include damp waste, for example contaminated blood, residues form the OP area of hospitals, or from pathology, a homogenisation of the sterilised mass and a dry preparation, while it is possible to dispense with the homogenisation as a rule in the case of dry contagious masses. For the last mentioned materials, it is particularly advantageous to employ to implement the process a steriliser which, being mounted on a motor vehicle or the like displaceable support, permits a combination of contagious materials which are present at different places and which are then sterilisable directly in this steriliser serving as transport container, connected to a suitable steam vacuum and reduced pressure source.

Abstract: Ceramic materials intended for cutting and consisting of aluminium oxide with additives of hard carbides or nitrides, above all titanium carbide, have up to now, because of their sintering inertia, in general been pressure sintered to obtain satisfactory properties. According to the invention a ceramic alloy of excellent technological properties now exists and consists principally of Al 2 O 3  and hard nitrides or carbonitrides, such as first-hand TiN orTi(C, N). This has been performed by providing the alloy with a certain fraction of an Al-O-N-compound, such as nitrogen stabilized aluminium oxide with cubic or nearly cubic structure.
