Patent ES-337928-A1 (ES)
Title: Electroetching an aluminum plated semiconductor in a tetraalkylammonium hydroxide electrolyte
IPC: H01L23/485
Filed: 1967-02-24
Abstract: In fabricating a semi-conductor device, an Al layer on a semi-conductor body (e.g. of Si) is electrolytically etched in an aqueous solution of tetraalkylammonium hydroxide R 4 N+(OH)- using a metal cathode so as to remove A1 from the layer. R may be methyl, ethyl, propyl or butyl. The four alkyl radicals in the compound may not all be the same but may be selected from the above radicals. As shown, a Si transistor element 10 of PNP configuration has thereon a silicon oxide mask 16, a Ti layer 17, an A1 layer 18 and a photoresist mask 19. Unmasked parts of the Al layer are electrolytically etched in a 2% aqueous solution of tetramethylammonium hydroxide at 25 C. The element may be suspended by metal tweezers which comprise one electrode connection. The cathode may be a Mo rod positioned one inch from the A1 surface. The electrolytic etching may be at 10,000 Angstroms per minute using 200 milliamps. Unmasked parts of the Ti layer are removed by chemical etching in a solution of dilute H 2 SO 4 and HF. Subsequently the photoresist mask is removed.
Patent ES-340516-A1 (ES)
Title: Pressure Reducing Regulators for Gaseous Fluids
IPC: G05D16/10
Filed: 1967-05-13
Abstract: A combined gas pressure regulator and safety valve comprises safety and regulating closure members 10, 11 carried by a common stem 9 secured to a diaphragm 4. The latter is loaded by springs 5, 14 the former of which is not effective until the outlet pressure as communicated to chamber 16 enters the diaphragm to disengage a flange of spring seat 7 from housing flange 8. Thus, when the system is idle or the gas supply fails, spring 14 urges the stem downwards to seat the safety closure member 10. To open the valve, a by-pass closure member 23 is unseated by depressing button 21 to allow gas flow to the outlet 3 via passages 26, 25, 27. When the outlet pressure rises to a value predetermined by the load exerted by spring 5, closure member 11 seats. In the modified bypass valve of Fig. 4 (not shown), resilient closure member (32) is unseated by pulling knot (21) to allow gas flow via passages (31, 26, 27).
Patent ES-340573-A1 (ES)
Title: Photographic shutter
IPC: G03B9/10
Filed: 1967-05-16
Abstract: An impact shutter comprises a blade 14 pivotably mounted on a stud 13 extending from a plate 11, which blade is rotated to uncover a lens aperture 12 by an impulse from an impact lever 26 applied so as to pass through the centre of percussion (C of P) of the blade, C of P being a distance d from the stud along the line through the centre of gravity (C of G) of the blade. The distance d is given by d = Ig/Mr+ #r where M is the mass of the blade, #r is the distance from the stud of (C of G) and I g is the moment of inertia of the blade about (C of G). An exposure is made by moving a trigger 36 clockwise as seen so as to slip off the impact lever 26 which then rotates under spring action thus hitting the blade 14 and eventually coming to rest against a stop 49. The blade 14 is pivoted clockwise until a lug 20 thereof engages a rebound member 50 when the blade is returned to its closed position with a spring 15 holding it against a stop 19. The rebound member 50 is connected to a speed adjusting lever 52 the position of which can be varied, thereby varying the shutter speed. For each speed setting except the slowest the blade rebounds off the member 50. For the slowest speed the spring 15 returns the blade to its closed position before the member 50 is engaged. The shutter may be self-setting or may be reset manually or by actuation of film advance mechanism. The blade 14 may be of the type having an arcuate opening therein, which opening is moved into and out of alignment with the lens aperture 12. With impulses from the impact lever 26 and from the member 50 passing through C of P little or no shock is transmitted to a camera causing camera movement during exposure, and thus shutter speeds of up to 1/2000 sec. may be obtained.

Patent ES-345096-A1 (ES)
Title: Pulse detection apparatus
IPC: H04L25/08
Filed: 1967-09-15
Abstract: In a pulse-shaping and delaying circuit, a transistor T1 is biased in the non-conductive direction by a voltage derived by integrating the input signals in one circuit (R2, D2, C5), the pulse being fed to the input of the transistor T1 by a second integrating circuit (R3, D3, C6) so that the transistor T1 only becomes conductive after a time dependent upon the time constants of the two integrating circuits. The output of T1 is also coupled to a further pulse forming circuit (Fig. 3) via a diode D5 controlled by input pulses via a further integrating circuit (R1, C4, D4). As shown, pulses at E having a duration of 100 Ás., the shortest interval between two pulses being 20 Ás., are fed via an interference-removing low-pass filter TP and an integrating circuit R3, D3, C6 having a time constant of 24 Ás. to the base of T1. Each negative-going input pulse at E cuts off diode D3 and allows T1 to become saturated after a delay due to the discharge of C6, giving a positive-going step at the collector. The output terminal T2 is normally isolated by a diode D5 until diode D4 becomes non-conductive after a delay due to the charging of C4, when D5 passes the collector pulse to the output terminal T2. The output pulses terminated by T1 being turned off by the trailing edge of the input pulse at E. The pulse at T2 may be fed to a monostable pulse-shaping circuit or, as shown in Fig. 3, to a circuit comprising a series-connected pair of transistors T2, T3. T3 is normally conductive, holding the output terminal I at 12 V. until a pulse arrives from D5 when T2 becomes saturated, setting the output A to 0 V., the voltage dropped in D7 turning off T3 for the duration of the pulse.

Title: Sensing circuit having regenerative latching circuits responsive to threshold differences in biasing voltages derived from a pair of differentially variable currents
IPC: H03K3/013
Filed: 1969-12-12
Abstract: A sensing circuit, more particularly for bipolar read-out pulses from a magnetic core or thin film store comprises a differential transistor amplifier 16 and two bi-stable circuits 22, 221 each receiving inputs from both transistors of the amplifier so that one or other switches to its second state if the amplifier is unbalanced. As shown, the bi-stable circuits are Schmitt triggers which are normally in one state but in response a strobe pulse at 70 and an output from the sense/inhibit line 40 one or other is changed in state by the resulting difference between the voltages V 1 and V1 2 or V1 1 and V 2 . The strobe pulses are timed to occur at a low noise point of the input pulses and also effect resetting of the bistable circuits. The outputs may be commoned by transistors 68, 681 to provide a monopolar output.
