Patent ES-367242-A1 (ES)
Title: Coupling of bistable elements by conductivity modulation
IPC: G11C19/28
Filed: 1969-05-04
Abstract: Bi-stable semi-conductor devices are coupled by intermediate semi-conductor regions which include a "conductivity modulation" region receiving minority carriers drained from an accumulation region of the preceding bi-stable device and connected to the accumulation region of the next device. In the shift register shown, if a first thyristor 1 is conductive, lowering the terminal 36 to a negative voltage causes the upper base of a double base diode to become negative and thus the emitter 17 to become conductive. Minority carriers thus drain from the accumulation region adjacent the gate of the thyristor and switch the thyristor off. The carriers transferred to the conductivity modulation region of the double base diode allow the latter to conduct when the voltage at 36 is restored and this either fires the next thyristor or confirms its conductive condition. If thyristor had initially been off, the double base diode would not have fired thyristor 2 and if it were on the action of the second double base diode 2 would have switched it off. Diodes 21 and 25 prevent false operation due to reverse currents. In Fig. 2 (not shown), the thyristors are replaced by four-electrode double base diodes, the emitter electrodes being connected to the upper base by a diode (not shown) to provide a low resistance path during the shift pulse and thus to prevent false firing. The connection (67) corresponding to 16 may be a hook collector. The circuit may be made in integrated circuit form and it is stated that some of the connections could be in point contact form. It is also stated that the invention could be applied to a ring counter.

Filed: 1969-09-23
Abstract: An aerial system for the simultaneous transmission and reception of two waves which are orthogonally polarized and which differ in frequency by an amount equivalent to a desired intermediate frequency, comprises a primary horn radiator 1, Fig. 1, which faces a reflector 11, and which is supported by stays 12, 13, 14, 15 from said reflector. Coaxial feeders 16, 17 from the rear of the reflector 11 extend along the stays 12, 13 into the horn 1. Said horn comprises a rectangular cross-section waveguide portion, which is terminated by a shortcircuiting plate 4, Fig. 2, at the rear, and which is flared out to a rectangular aperture in front. A transmitting probe 2 extends from the feeder 17 into the horn, near the aperture. It is disposed parallel to one pair of sides of the rectangular horn, and is fitted with a rod 23 of dielectric material to improve matching. A receiving probe 3 is constituted by a semiconductor diode which is disposed parallel to the other pair of sides of the rectangular horn and near the short-circuiting plate 4. The crosssection of the rectangular horn in the region of the short-circuiting plate may be such as to support the fundamental mode of the received waves, and the long side of the rectangular aperture of the horn may be parallel to the electric field of said waves. The casing of the diode of the probe 3 is secured to one wall of the rectangular cross-section waveguide portion of the horn, and a pin from its other side extends into a coaxial plug 26, for the feeder 16. To improve matching, the probe 3 is displaced away from the centre-line of the said rectangular cross-section, and a choke coupling 27 is provided for the plug 26. The probe 3 picks up a small portion of the energy transmitted by the probe 2, although it is orthogonally polarized, and this is heterodyned with received energy in the diode to produce an output at the intermediate frequency on the feeder 16. In another embodiment, a receiving probe (30), Fig. 3 (not shown), extends into the horn near the shortcircuiting plate from an associated semiconductor diode (31) outside the waveguide portion of the horn. A dielectric material rod (32) is fitted to the probe (30), to improve matching.
