Abstract: Disclosed herein are an improved method and apparatus for optically reading pre-recorded magnetic information on a magneto-optic recording element. The invention addresses the technical problem of minimizing the adverse effect of unpredictable variations in the state of polarization of the beam of radiation used for read-out. Such variations may be produced, for example, by birefringence variations in a transparent layer or substrate through which the recorded information is recovered. According to the invention, the undesired polarization variations are sensed from the system's output signal, and an error signal representative of such variations is produced. Such error signal is used to adjust the state of polarization of the read-out beam prior to detection by the system's detector elements. Preferably, the read beam is directed through the combination of a quarter-wave plate and a Faraday rotator, and the error signal is used to control the magnetic field of the Faraday rotator. In effect, the combination of the quarter-wave plate (QWP) and Faraday rotator (FR) behaves like a variable phase retardation plate as far as the resultant output signal is measured by differential detection is concerned.

Abstract: A load is supplied by transformer 10 supplied via a voltage regulator and thyristor network. The thyristor network and regulator are simultaneously controlled to respond to changes in the load and in practice the thyristors respond rapidly and are re-adjusted as the regulator is inherently more slowly adjusted. The result is that the thyristors produce minimum reflected harmonics overall in the mains and an optimum power factor can be achieved for each power setting.

Abstract: An inductive sensor arrangement exhibits a transmitter coil (1) which is fed by a high-frequency oscillator (3). The transmitter coil (1) generates a spatial electromagnetic field (5). Two coil arrangements (6 and 9) in which a current is induced by the transmitter coil (1), are inductively coupled to the transmitter coil (1). Two first receiver part windings (6a, 6b) are arranged in such a manner that they are exposed to different induction with an unsymmetric position with respect to object irregularities, for example gaps in a metal body. This makes it possible to detect lateral offset signals of the part windings (6a and 6b) with respect to the irregularity (4c) of the object (4). Such signals, which indicate the lateral offset of the object irregularity, can be obtained by directly or indirectly connecting the outputs of the two part windings (6a, 6b) in opposition to one another. In addition, a second coil arrangement (9) is provided which exhibits an equal number of receiver part windings (9a, 9b) to the first coil arrangement (6). The part windings (9a, 9b) are arranged approximately in line with the part windings (6a, 6b) above the object. By comparing the output signals of the associated part windings of the two coil arrangements (6a, 9a and 6b, 9b), signals can be obtained which have a relationship to the distance between the sensor arrangement and the metallic object (4). If the distance signals of the two pairs of part windings (6a, 9a and 6b, 9b) differ from one another, correction signals can be obtained from this. <IMAGE>

Abstract: A method and structure is provided to test for leakage currents in a fuse array (208). A diode (170-1-170-M) is connected to each column in the array in order to isolate the column (280-1-280-M) from the test circuitry during normal operation of the device. During testing, current is fed through a diode (170-1-170-M) to a column, and the corresponding leakage current is measured. In one embodiment, the anodes of each diode are connected in common to a single test point (175), and the total leakage current from the entire fuse array (208) is measured simultaneously. In another embodiment, addressing means are used to selectively address a desired one of the test diodes and thus a corresponding one of the columns such that leakage current through a single column. In another embodiment, regardless whether all of the columns are simultaneously accessed or are addressed individually, rows are individually addressed in order to enable measurement of leakage current of either a single fuse, or the total leakage current of the fuses associated with an entire row, respectively.

Abstract: In an intrinsically safe igniting and safety circuit for a gas burner, for the temporal determination of a purging period, a first charging capacitor (C2) is charged via a first diode (D1) and the series circuit of the exciter windings of a closing relay (GR) for the solenoid valve (V) and of a bistable safety valve (SR), without in the course of this one of the two relays responding. As soon as the voltage at the first charging capacitor exceeds a predetermined value, an operational amplifier (OP) switches through a first electronic switch (T2) connected from the junction (P1) of the two exciter windings to earth. The closing relay responds, opens the gas supply via the solenoid valve and sets an ignition spark generator in operation. A delay circuit, consisting of a second charging capacitor (C4) which can be charged from the first charging capacitor (C2), two voltage dividers (R4, R5; R7, R8) and an operational amplifier (OP), lays down a given delay time by discharging the second capacitor (C4), after which the first electronic switch (T2) closes again. The installation is thus cut out by dropout of the safety relay, unless a flame detector circuit (FS) connected to a flame detector (FL) previously switches through, on the appearance of a flame within said safety time, a second electronic switch (T1) connected parallel to the first electronic switch (T2) and thus forms a holding circuit for the closing relay. <IMAGE>
