Title: Extrusion of workpieces
IPC: B21C23/00
Filed: 1970-09-30
Abstract: 1324607 Extrusion WESTERN ELECTRIC CO Inc 30 Sept 1970 [1 Oct 1969] 46492/70 Heading B3P An extrusion apparatus which operates continuously comprises a die element 136, Fig. 2c, and billet grippers 130, Fig. 2b, and 116, Fig. 2a which are relatively movable so that the billet 12 is extruded into wire 14 continuously. The grippers comprise a stationary set 116 mounted to a fixed plate 19 and a movable set 130 mounted on a reciprocable cylinder 23. The cylinder is moved by opposed hydraulic units 20, 21, 42, 43, Fig. 1, and maintained in compression. Each gripper set comprises a set of segments 152, Fig. 5a, movable inwards by fluid pressure in a duct 158 and outwards by fluid pressure in channels 168. The gripper set 116 is normally maintained open by fluid in a chamber 118 from a supply 122. The movable gripper set 130 is normally maintained closed by fluid pressure from the extrusion pressure chamber 142. The fluid pressure to operate each gripper set is supplied under the control of servo-valve in dependence on the movement and position of the cylinder 23 and the die. The fluid pressure in the extrusion chamber 142 is controlled by an apertured sleeve 144 which seals ducts 145 when the pressure increases as the ram advances and allows refilling on retraction of the ram. The extrusion is effected hydrostatically and the fluid spaces the billet from the die and flows out therewith. In operation the ram 45, Fig. 6a, with the die element 136 is advanced while the billet 12 is gripped by the stationary gripper set 116. Before the end of the advance the billet is gripped by the gripper set 130 and advanced as the ram 45 slows down to keep the extrusion constant. The ram is retracted and the gripper set 130 advanced at a quicker rate by movement of the cylinder 23. The billet is gripped by the gripper set 116 for the next advance of the ram and the retraction of the gripper set 130. The working fluid may be castor oil with molybdenum disulphide. The billet may be sized by a die 15, Fig. 2a, before extrusion.

Title: Manufacture of electrical heating mats
IPC: H05B3/36
Filed: 1973-10-09
Abstract: 1448700 Flexible heating tape PATENTKONSORTIET ROBERT MEINICH & CO 9 Oct 1973 [13 Oct 1972] 46982/73 Heading H5H A flexible heating film comprises a plurality of narrow parallel conductive strips 5 interconnected at opposite ends by a series of short transverse conductive strips 6 to form a meander heating pattern, the strips 6 being formed from transverse strips, e.g. 9 which extend across all all of the longitudinal strips 5 and the strips 5 and 6 being sandwiched between insulating foil layers 2, 3 which are joined together, e.g. by heat sealing, in those areas which are in direct contact. Terminal connector strips 7 are provided at one end of the film. A hot melt adhesive 8 or adhesive tape may protect the two ends of the heating film. In production metal foil 11 is fed to rotating knives 15 to slit it longitudinally. Next, spacers 17 separate the narrow foil strips 5 produced by a gap corresponding to the gap between the longitudinal strips 5 in the finished product. After a lower insulating web 2 has been introduced, transverse connectors 9 are applied across the entire width of the web, an upper insulating web 3 is applied, the webs 2 and 3 are heat sealed together during passage through a welding device 20 and the transverse connectors 9, which comprise copper strips with the underside coated with lead, are soldered to the strips 5 by heated pressure rollers 22. As shown, the strips 9 having staggered notches from opposite side edges is produced from a continuous strip by a pair of punches as it is fed to the moving web 2 and strips 5. When the finished web is cut to length along the centre of the strip 9, the overlapping of the notches from the opposite edges ensures that the separate short connectors 6, joining only two adjacent strips 5 are formed. Alternatively the strips 9 need have no notches, the individual short connectors 6 being formed therefrom by cutting the strips 9 transversely between every second strip 5. Finally the strips 9 may be replaced by correctly sized and spaced short connectors carried on an insulating carrier strip so that no subsequent operation is needed to divide the transverse connector into separate short sections. Wide sections 2 containing no resistive strip 5 are provided along opposite sides of the film to enable the film to be nailed in position. The resistive foil strips 5 are preferably made of lead-tin-antimony alloy and are thinner than the connectors 6 so that the heating effect is determined predominantly by the strips 5.

Title: Method of making field effect transistors
IPC: H01L27/088
Filed: 1970-10-15
Abstract: 1298375 Semi-conductor devices HITACHI Ltd 15 Oct 1970 [17 Oct 1969] 49045/70 Heading H1K In a method of making an IGFET the opening for the gate region diffusion is determined by the edge of the gate electrode. An IGFET comprises a drain region 12a, of low impurity concentration formed in a silicon substrate of the opposite conductivity type, and isolated by diffused walls 14. An oxide layer 13 overlying the drain region is removed and replaced by an insulating film 15 of SiO 2  or Al 2 O 3 , Si 3 N 4 , SiO 2  and P 2 O 5  or SiO 2  and Al 2 O 3  to form the gate insulation. A gate electrode 17 of polycrystalline silicon, molybdenum, tungsten, titanium, or tantalum is formed on the layer 15, and using photo-resist techniques an opening 18 is made in the insulating layer, the opening being bounded on one side by the edge 17a of the electrode 17, which acts as a mask for that part of the opening. An impurity of the substrate conductivity type is diffused through the opening 18 to make contact with the substrate, and subsequently a diffusion of the drain conductivity type is also made through the opening 18 to form a source region 22. This double diffusion causes a gate region to be formed between source and drain by the first diffusion, the gate width being determined by the difference in lateral diffusions of the two diffusion steps. This gate region may be only 0À5 Á in width. Simultaneously with the source diffusion a diffusion may be made to give a higher impurity drain region 23. Contacts are later made to the drain and source regions, and gate electrode to form the IGFET. The dopants may be of boron and phosphorus, and the contacts of aluminium. In a second embodiment, one source and gate diffusion may be used to form a device having two drains and two gate electrodes. In another embodiment the source and drain region may be formed in a pocket in the substrate. In a further embodiment, the gate diffusion is of less depth than the low impurity drain region, but contacts one of the isolation walls, enabling an integrated circuit to be formed comprising an IGFET and a bipolar transistor, the gate diffusion being simultaneous with the base diffusion of the bipolar, and the source and drain regions being formed simultaneously with the emitter diffusion.
