Patent ES-297430-A1 (ES)
Title: Photo-sensitive device including layers of different conductivity types
IPC: H01L21/00
Filed: 1964-03-10
Abstract: A photo-sensitive device has a supported layer of lead monoxide containing a region of high conductivity in direct contact with an intrinsic or substantially intrinsic region which forms the active part of the device. In operation the high conductivity region is arranged to act as an optical filter for the active region as well as acting as a current supply region. In one embodiment a photo-cell has a transparent glass support bearing a transparent electrode of tin oxide or gold. Over this a lead monoxide layer is formed by vapour deposition. The layer is made either distinctly N-type by forming it with excess lead or by doping with bismuth or antimony or distinctly P-type by forming it with excess oxygen or by doping it with thallium. The layer is built up by depositing further lead oxide from an atmosphere containing both oxygen and a donor gas such as water vapour, the relative amounts of these being adjusted to give impurity compensation. This part of the layer may be given increased red sensitivity by doping it with sulphur, selenium, or tellurium. A second electrode of silver or gold is then applied by vapour deposition and a transparent cover sealed to the support. In operation, light is shone on to the cell through the support and high frequencies are absorbed in the highly conductive region and only the longer wavelengths reach the intrinsic region which is the effectively active part of the device. By making highly conductive layers of increased thickness the response of the cell may be taken to longer wavelengths. X-rays, however, can penetrate the conductive region and activate the cell. If the cell is exposed to light through the transparent cover intervention by the filter is avoided and the effective response extended. A second embodiment is a glass-cased vidicon camera tube. A transparent tin oxide or gold electrode is provided on its window. Over this a strongly N- type layer of lead oxide is deposited. Bismuth, antimony, water, or mixtures thereof may be used to obtain the desired doping. An intrinsic or substantially compensated layer of lead oxide is deposited over this and may contain sulphur, selenium, and/or tellurium to increase its longwave response. At its free surface this layer is provided with a thin P-type layer having no appreciable transverse conductivity. Again the highly conductive N-type layer acts as an optical filter and if desired its thickness may be increasd to such an extent and it may contain sulphur, selenium, and tellurium so that the tube responds only to X-rays.

Title: Phase shifting circuits for color television receivers
IPC: H04N9/64
Filed: 1967-05-20
Abstract: In a colour television receiver adapted to receive an NTSC type subcarrier, the hue of the colour picture is adjusted by means of a phase-shifting circuit (part of phase-shift circuits 24, Fig. 1) coupled between the output of a colour reference oscillator 21 and an automatic frequency and phase control detector 22 which utilizes the separated burst component from burst separator 20 to synchronize the generation of the colour reference oscillation in oscillator 21 with respect to the burst component. Detector 22 which includes a balanced phase detector produces a correction voltage representative of the phase and frequency difference between the separated burst component and the phase shifted colour reference oscillation coupled across the phase-shifting circuit. The phaseshifting circuit comprises the series combination of an inductor and a capacitor and a variable resistance coupled across the capacitor, Fig. 2 (not shown), and the phase is shifted by changing the resistance of the variable resistor, the circuit being such that its impedance remains constant throughout the range of the variable resistor. Preferably, the inductive reactance of the inductance equals one-half the capacitive reactance of the capacitance at the frequency of the colour reference oscillations and a fixed capacitor having relatively high impedance is coupled between the colour reference oscilator and the phase shifting circuit. The variable resistance may be mounted on the front panel of the receiver and be coupled to the capacitor by means of a shielded cable, the capacitance of the cable being added in parallel to that of the capacitor and the value of the capacitor being selected to meet the above impedance requirements.

Patent ES-362681-A1 (ES)
Title: Connecting and disconnecting system for switching equipment
IPC: H04Q3/00
Filed: 1968-01-18
Abstract: In an exchange having a switching network consisting of mechanically latched cross-bars, the release of operated cross-points is effected just prior to the setting up of a new connection and not immediately on termination of the connection to which they relate. As shown, looping of a caller's line lg1 is detected in his line circuit JA1 and the marker MQ connects it via singlestage cross-bar switch CCA to the inlet of oneway feedbridge AL1 if this is free. It should be noted that the feedbridges are one-way, only in respect of call-setting and not in respect of speech transmission and moreover, each group of subscribers may have access to more than one feedbridge via their single switch. The feedbridge seizes a free register EN which reverts dial tone and then accepts dialled digits from the caller. The identity of the called party, e.g. lgm, is passed to the marker and stored on a relay contact tree (Fig. 2, not shown). A relay sequence switch is effective thereafter to successively transmit disconnect signals to the vertical magnets of column 1 in switches CCA and CCC whereby any actuated cross-points in these columns are released. The sequence switch then applies signals to the vertical magnet of column 1 and to the horizontal magnet of row 1 in switch CCB whereby already operated crosspoints, if any, in the column are released and, virtually simultaneously therewith, the required cross-point is closed so as to connect the called line to the outlet s of the feedbridge. The register indicates ringing and then withdraws followed by the marker.
