Title: Apparatus for forming a plurality of axially spaced beads in a hollow, substantiallycylindrical sheet metal blank
IPC: B21D22/06
Filed: 1964-09-17
Abstract: A method of corrugating a sheet metal cylinder (12) comprises placing the cylinder on a die unit (13, Fig. 3), including radially movable die segments (14), expanding the die unit to form a corrugation, and successively forming further corrugations whilst holding the cylinder by engaging one or more of the corrugations already formed and permitting the unformed portion of the cylinder to move towards the corrugation being formed. The die units may equal in number the corrugations to be formed, each arcuate segment (14) of a unit having a stem (18) guided in a passage (20) formed in a casing (21). The passages are staggered (Fig. 4), so that the segments may be juxtaposed. A roller (19) on the stem (18) is engaged by a core (15) movable by a fluidpressure cylinder (24) to expand the segments against the force of return springs (16) in grooves (17) in the segments. The outer surfaces of the segments are formed by rubber rings (31). The core has a cylindrical guide portion engaging the bore of casing (21) and one or, if the core is to operate in both directions, two tapered ends. Slots are formed in the core which are in axial alignment with the rollers (19), and in the slots are cams (27) adjustable by a screw-threaded conical sleeve (28). As the core moves along the cylinder, the straight portions of the cams retain three of the die units expanded to hold the cylinder as a further corrugation is formed.

Patent ES-349367-A1 (ES)
Title: Improvements in and relating to semiconductor devices
IPC: H01L21/00
Filed: 1968-01-16
Abstract: A semi-conductor device such as an integrated circuit comprises a semi-conductor body having a portion 1 of one conductivity type and one or more islands 2 of the opposite type adjoining one surface of the body and forming electrically separating PN junctions 3 with the portion, at least one semi-conductor circuit element (e.g. transistor, diode, resistor, capacitor or multi-layer structure) incorporating a zone 5 of the one conductivity type being formed in at least one island and the breakdown voltage of the junction 3 being lower than the breakdown voltage between the zone 5 and the island. The breakdown voltage of the junction 3 is determined by a local, more highly doped, zone of the portion 1, preferably in the form of a separation channel 7, and a local, more highly doped, buried zone 8 of the island, the more highly doped zones being separated by, and defining part of, the PN junction 3 and the impurity concentration characteristic of the one conductivity type in the zone 7 having a maximum adjacent the part of the junction defined by the zones 7 and 8. In one method of making the device, arsenic is vapour-deposited on one surface of a silicon wafer 1 and diffused into the wafer in an oxygen atmosphere to form the highly doped zone 8 and an oxide layer (9, Figs. 3-7, not shown). A channel (10) enclosing the island 2 is etched in the oxide layer, the exposed silicon is etched to a depth of a few tenths of a micron, and boron is vapour-deposited to form a highly doped region (11) which is then diffused through the zone 8 to reach the portion 1. This is possible because boron diffuses about ten times as fast as arsenic. The oxide layer is then removed, an epitaxial layer 4 is grown on the surface, and a further oxide layer 12 is formed on the layer 4 and provided with a channel (13) immediately above the region (11). Boron is vapour deposited in the channel (13) and diffused into the layer 4 to meet the region (11) to form the highly doped separating channel 7, and simultaneously with this diffusion, or subsequently, boron is diffused through a suitable opening in the oxide layer to form the base zone 5 of a transistor. Phosphorus is then diffused-in to form the emitter zone 6 and collector contact zone 28 and finally aluminium is deposited to form contacts 18-20. The circuit is connected to voltage sources V 1 , V 2 in such a way that the voltage difference V 1 between the portion 1 and the base zone 5 is smaller than the difference between the breakdown voltages defined above. When the voltage V 2 is increased the junction 3 breaks down before the breakdown voltage between the base zone 5 and the collector zone 4 is reached so that damage to the transistor is prevented.
Patent ES-355077-A1 (ES)
Title: Method of forging blanks, notably crankshafts
IPC: B21K1/08
Filed: 1968-06-15
Abstract: A crank-shaft is forged from a billet 1 by a pair of dies 4, 5 which are held in a movable die block 2 and a fixed crosshead 3 respectively and the die block is moved in a direction at an angle to the billet axis to upset the billet and form a crank-shaft web between the dies. The size of the web may be determined by the volume of the billet or by a retaining die ring 6 so that the dies 4, 5 and the ring form a closed die. The bearing faces of the dies 4, 5 may be initially non-parallel, Fig. 7 (not shown), so that the crank-pins formed are non-parallel when the dies are abutted. A double set of tie-rods or columns 9, 10 are provided to absorb the forging load and intersect at the centre of gravity of the formed web. The die block 2 is raised by piston-cylinder assembly 8 and slides on a slideway 12 of the press frame 11. The apparatus can be modified for multi-throw crank-shaft forging, Fig. 10 (not shown). This apparatus comprises a pair of two-part dies (14), (15), mounted in a fixed crosshead (17) and a slide (16). The crosshead and slide each have apertures (18), (19) aligned with the die apertures to allow axial movement of the billet for the separate forging of each throw. The billet is rotated about its axis and/or a transverse axis after each forging to correctly position the crankpins. The billet may be forged hot or cold and heaters in the form of induction heaters or gas burners may be provided in the device.
