Patent ES-482395-A1 (ES)
Title: Controlled-avalanche tension transistor that can be sensitive to a magnetic field.
IPC: H01L29/82
Filed: 1979-07-11
Abstract: A heretofore undiscovered suddenly conducting avalanche voltage effect is described with relationship to a new family of hybrid transistors. The devices constructed also exhibit magnetic sensitivity. The magnetic responsiveness of such devices creates a new family of magnetic sensors which utilize magnetic modulation of the avalanche voltage produced by the new effect. New transistor structure elements are incorporated in the devices. These include an impact ionization promoter means and an intrinsic, or high resistivity, depleted base region which extends at least partially from a collector toward an emitter. Minority carrier injection efficiency control means and transportation efficiency control means are also included. The character of the base region extending between the emissive junction and the collector is carefully controlled so that the product of the ionization current multiplication factor M and an electron-hole recombination probability factor alpha is less than unity. Within limits, any specifically desired avalanche voltage can be created by controlling the characteristics of the transistor structure. This voltage may then be varied bidirectionally by magnetic fields to form a new class of magnetic sensors.

Patent ES-8103301-A1 (ES)
Title: Automatic adjusters for drum brakes
IPC: F16D65/56
Filed: 1980-05-21
Abstract: A vehicle drum brake comprises an automatic adjuster with thermal compensation, so that the brake does not become over-adjusted following thermal expansion and subsequent contraction of the drum. The adjuster overcomes the problems associated with adjusters which at high temperatures are disabled, and so might leave the brake under-adjusted. The adjuster comprises a bimetallic strip or equivalent incorporated into the adjuster strut to expand the strut when the drum expands, and to contract the strut when the drum contracts. Thus the adjuster takes up excess slack due to lining wear, but not that due to drum expansion. The adjuster is suited for use on those drum brake adjusters where the strut is lengthened by operation of the service brake actuator, and not of the handbrake actuator.

Title: Data receiver adapted to receive a modulated signal and method of operating such a data receiver.
IPC: H03H21/00
Filed: 1980-09-12
Abstract: In a multipoint data communication system using quadrature-amplitude modulation, a master modem (20) and a plurality of tributary modems (11a, 11b . . . 11n) are interconnected via respective transmission channels (13a, 13b . . . 13n, 16). Adaptive equalizer circuitry (55, 56) in the master modem equalizes the channel from a particular tributaryly multiplying samples of signals received from the tributary by an ensemble of tap coefficients associated with the tributary. The tap coefficient ensembles for each tributary are stored in a memory (91) from which they are retrieved at the start of transmission from that tributary. Timing-acquisition circuitry (29) within the master modem adjusts the phase of the letter's sampling circuitry (23, 27) at the start of transmission from a given tributary so that the received signals are sampled at the correct time points. In particular, a timing acquisition signal having spectral components only within the non-rolloff region of the equalized baseband-equivalent transfer function is transmitted by the tributary. The master samples and equalizes the received timing acquisition signal to form a succession of timing acquisition equalizer outputs. The time by which the operation of the sampling circuitry is to be advanced or retarded is determined as a trigonometric function of two successive ones of the timing acquisition equalizer outputs. The timing acquisition signal is illustratively a double-dotting pattern having a four-symbol-interval period. That period is integrally related to the carrier frequency. This allows the samples needed in order to begin forming the timing acquisition equalizer outputs to be generated by replicating the samples taken over only four symbol intervals.

Title: Electromagnetically operable ram actuator in particular for impact printers
IPC: H01F7/13
Filed: 1981-05-13
Abstract: An electromagnetic ram actuator, the electromagnet of which consists of two symmetrically designed magnetizable yoke halves. The facing pole ends of the yoke halves are in each case essentially semicircularly recessed, forming two aligned essentially circular operating gaps. Between the operating gaps a ram is arranged which is shiftable in the direction of their line of alignment and whose cross-section is adapted to the area of the operating gaps. The ram comprises two armature disks of magnetizable material and a spacer element arranged therebetween consisting of predominantly non-magnetizable material. One armature disk is associated with each operating gap. The armature disks are geometrically designed in such a manner that their volume is of the order of the operating gap volume. In the starting position of the ram the armature disks are positioned in front of the operating gaps of the electromagnet in its non-excited state. Upon excitation of the electromagnet, they are pulled into its operating gaps, being accelerated in the process. The ram actuator is particularly suitable for use in impact printers.
