Patent ES-343349-A1 (ES)
Title: Pattern deposit by laser
IPC: B23K26/12
Filed: 1967-07-22
Abstract: In a vapour deposition process of forming a pattern of a material such as Pt on a first substrate, e.g. cellular Si, the material is evaporated from a layer of said material on a second substrate in juxtaposition to said first substrate by focusing a converging beam of intense radiant energy, e.g. a laser beam on to the second substrate, the required pattern being formed by relative movement of the substrates with respect to the focus of the radiant beam. As shown in the Figure, infra red radiation from a laser is directed via mirror 1, compound lens 10, optical flat 8 on to substrate 5 of glass having a Pt film 7. A substrate 4 is spaced 50 microns beneath substrate 5 by mica separator 6. The substrates are mounted in vacuum vessel 3 on a co-ordinate table 2 which is moved during deposition to produce the required pattern. The deposited pattern forms the interconnections between the devices in an integrated circuit.

Title: Drum brakes
IPC: F16D65/22
Filed: 1967-09-23
Abstract: In an actuator of the roller expander type for a drum brake, two oppositely displaceable tappets 14 have opposed inclined ends each engaged by one or more rollers 36, rotatable on a common shaft 32 movable at least in line with the tappet axes so as to accommodate unequal wear of the brake shoes 46. As shown in Fig. 2, the tappets 14 have rectangular cross-section and are displaceable within rectangular openings of a body 10 by downward movement of a pull rod 40. Each tappet 14 has an end 16 of circular section engaging carriers 44 for brake shoes 46. The carriers 44 may be omitted. Three rollers 36 of equal diameter are pivoted on a pin 32 in a yoke 28 and arranged so that the outer rollers engage only the right hand tappet 14 whilst the centre roller engages only a land formed on the inclined edge of the left hand tappet 14 (see Fig. 4). The head 42 of the pull rod 40 and a collar 30 have part-spherical surfaces to allow movement of the pin 32 parallel to the tappet axes. In Fig. 5, the tappets 50 have circular cross-section, rotation being prevented by rectangular bearing pads spigotted on to the inclined end faces of the tappets. The yoke 58 is centralized within the housing 52 by engagement of the bearing pads 54 (Fig. 4) between the inner surfaces of the yoke. The bearing pads 54 are of different size, incorrect assembly being prevented by a lug 66 formed in the cover 64. The actuator is mounted behind a brake back plate so that the pull rod 62 projects at an angle of 11 degrees 30 minutes to the normal. In Fig. 9 (not shown), roller bearings are interposed between the common pin and each roller, whilst in Fig. 8 (not shown), the centre roller is replaced by two parallel rollers.

Title: Tone decoder having plural reference tones
IPC: H04L27/144
Filed: 1968-01-05
Abstract: The frequency of an input signal f(t) which may have any one of n predetermined frequencies is determined by mixing the input signal with n-1 reference frequencies and feeding the resultant n-1 beat signals to associated low pass filters which each generate an output signal when the input signal f(t) is one of the pair of frequencies adjacent the associated reference signal. The combination of outputs from the filters represents the frequency of the input signal. In the embodiment described in which the input signal may have one of three frequencies the outputs from the filters 25, 26 are fed to detectors 27, 28 which generate a " 1 " signal in response to an output signal from the associated filter, the outputs from the detectors being fed to AND gates 31, 32, 33 and inverters 29, 30 so that a signal is generated on one of three lines 1T, 2T, 3T to control a device 34.

Title: Encapsulated microelectronic devices
IPC: H01L23/538
Filed: 1969-05-27
Abstract: An assembly of integrated circuit clips 10, Fig. 3, embedded in a block 20 of cast encapsulating material with their surfaces, provided with terminal pads (16), Fig. 1 (not shown), exposed and the terminal pads interconnected by conductors 28 overlying the surface of the block 20, is formed by casting encapsulating material in a mould in which the individual clips are arranged with their surfaces against one face of the mould and subsequently removing the one face of the mould to expose the terminal pads of the clips so that conductors can be formed on the surface of the block. As described the clips comprise a substrate (12), Fig. 1 (not shown), of semi-conductor material having operative elements 14, e.g. transistors, diodes and resistors, and terminal pads 16 formed thereon. Each clip may be bonded to a metal pin 22 of, e.g. gold-plated alloy of nickel and iron, acting as a heat sink. The clips are located face downwards on a glass plate (32), Figs. 6-8 (not shown), backed by a mirror (31), using a microscope (38), the required positions of the clip and the mould walls on the plate having previously been marked, e.g. by etching, on the surface of the plate. The clips and mould walls are held in position before encapsulating by an adhesive, e.g. a silicone material in a solvent or carnauba wax. The encapsulating material may be a ceramic, e.g. magnesium carbonate or a silicon dioxide material or an epoxy resin which may have a mineral filler. After the material has set and the glass plate removed, the interconnection conductors may be applied by sputtering alternating insulating 50, 56 and conductive 53-55, 58, 59 layers, Fig. 13, of silicon dioxide and aluminium on to the block, the sputtered materials being limited to selected areas by photo-resist techniques. Alternately insulating areas of glass and conductive areas of cermets may be applied as paint or ink through screen stencils.

Patent ES-454331-A1 (ES)
Title: Self-locking fasteners
IPC: F16B39/282
Filed: 1976-12-17
Abstract: The fastening element, e.g. a screw or a nut, has a plurality of rounded-off elevations on the surface which is directed towards the workpiece on which the fastening element acts. These elevations are formed as projecting ribs (2) which have at least one rounded-off portion which, when turning the fastening element relative to the workpiece, slide over the surface of the workpiece in the manner of rolling elements. In this arrangement, ribs hardly penetrate into the material of the workpiece at all. Rather, an essentially uniform fastening of the entire bearing surface of the workpiece beneath the head of the fastening element is effected. At the same time, a locking action with respect to unintentional loosening of the fastening element is achieved because the elastic/plastic deformations, which arise during tightening, of the material of the workpiece result, once the tightening procedure has been completed, in bulges between the rib elevations, which provide sufficient resistance against automatic loosening.

Title: Process for embossing a relief pattern into a thermoplastic information carrier
IPC: G11B11/00
Filed: 1977-05-03
Abstract: There is disclosed a method for embossing a relief pattern of high resolution into a thermoplastic information carrier by means of a heatable embossing matrix. The matrix, which exhibits the desired relief pattern, is pressed onto the thermoplastic information carrier, and is then heated by means of an electric current. After the electric current has ceased, the embossing pressure is maintained until the thermoplastic information carrier has hardened through cooling. Alternative methods permits selected variation of the relief pattern to be embossed by selectively altering the surface of the support member which supports the information carrier during the embossing operation or by selectively heating the embossing matrix.
