Patent ES-457351-A1 (ES)
Title: Capacitor storage memory
IPC: G11C11/34
Filed: 1977-03-30
Abstract: A semiconductor memory produced in a unipolar technology includes a cell which has an inversion capacitor with one terminal connected to a bit/sense line, the other terminal is coupled to a source of charges by a pulse from a word line. To provide a word organized array of these cells, each word includes a source of charges produced at the surface of a semiconductor substrate and plurality of inversion capacitors are formed also at the surface of the semiconductor in spaced apart relationship from the charge source. Information is written into the capacitors by applying voltages of two different magnitudes, representing 1 and 0 bits of information, to one terminal of the capacitors while a word pulse produces inversion layers at the surface of the substrate between the capacitors to interconnect serially the charge source with each of the capacitors. The capacitors having the larger voltage store the greater amount of charge. This charge can then be detected by measuring the voltage across the storage capacitors when a work pulse again connects the charge source with each of the capacitors.

Patent ES-8106990-A1 (ES)
Title: Pulse generator for a horizontal deflection system
IPC: H04N5/06
Filed: 1980-12-10
Abstract: A pulse generator is provided which may be advantageously used to produce a deflection drive signal in a television receiver. A capacitor is initially charged to a reference voltage level. Prior to the time at which the output pulse is to be generated, the capacitor is charged from a current source for a known time duration at a first rate. At the end of the charging interval, the capacitor has accumulated a known increment of charge proportional to the charge interval, and a new voltage level is established across the capacitor. The generator is now prepared to produce an output pulse. At a subsequent time, when the output pulse is needed, the capacitor is discharged at a second rate by a second current source. During the time interval that the second current source is discharging the capacitor, an output pulse is produced by the generator. A sensing circuit monitors the charge condition of the capacitor, and when it detects that the capacitor has been discharged to the initial reference voltage level, the sensing circuit disconnects the discharging current source from the capacitor, thereby terminating the output pulse.
