Abstract: Electrical supply apparatus including a plurality of switches serially coupled via inductor means to a power source said switches being operated alternately or sequentially to supply power from the power source via a supply circuit to a load and a protection circuit which comprises sensing means operative in dependence upon the voltage developed across each of the switches for initiating operation of a circuit breaker which is effective to decouple the apparatus from the power source if the switches are operated contemporaneously so as to short circuit the power source. 
     It will be appreciated that when a switch is conductive, a very low voltage will obtain across it. It will also be understood that current build up in the case of a short circuit will be retarded due to the influence of the inductor means which in one embodiment may comprise the inductive element of a tuned circuit. Thus by sensing the conductive states of the switches, conductive states of two or more switches which produce a power source short circuit, can be detected substantially immediately, whereby the circuit breaker can be operated before the current can build up to a damaging level. Thus by sensing voltage conditions which will eventually give rise to a large fault current, protection steps can be taken before the fault current can rise to a damaging level.

Abstract: A fast and brightly colored oxide film of aluminum which excels in durability and allows no separation of pigment is produced by using an aqueous dispersion of an organic pigment or carbon black finely divided to a size in the range between 3 and 150 nm, forming on the surface of aluminum an anodic oxide film containing pores larger in diameter than the ordinary pores, and causing the organic pigment or carbon black to migrate and deposit in the pores of the oxide film by means of electrophoresis. The formation of the anodic oxide film containing the pores larger in diameter than the ordinary pores is accomplished in the first method by subjecting aluminum to anodic oxidation at high voltage in an aqueous solution of acid. In the second method, the anodic oxide film is subjected either to a treatment of immersion in an aqueous solution of at least one acid selected from among phosphoric acid, sulfuric acid, oxalic acid, and sulfamic acid or to a combination treatment of immersion and AC electrolysis repeated in a prescribed number of cycles in said solution, to enlarge the pores in the anodic oxide film.

Abstract: A magnetic disk drive unit includes sensitivity correcting circuitry (6,7) which offsets a data head (2) outwardly from an on-track position by a given distance (X1), reads first and second servo information (A,B) to provide signals (V A ,V B ), and detects a difference (V1) between the peak values of the signals. Also, the circuit offsets the data head inwardly from the on-track position by a given distance (X2), reads the first and second servo information (A,B) to provide signals (V A ,V B ), and detects a difference (V2) between the peak values of the signals (V A ,V B ).

Abstract: A receiver for pseudorandom noise (PRN) encoded signals consisting of a sampling circuit, multiple carrier and code synchronizing circuits, and multiple digital autocorrelators. The sampling circuit provides digital samples of a received composite signal to each of the several receiver channel circuits. The synchronizing circuits are preferably non-coherent, in the sense that they track any phase shifts in the received signal and adjust the frequency and phase of a locally generated carrier reference signal accordingly, even in the presence of Doppler or ionospheric distortion. The autocorrelators in each channel form a delay lock loop (DLL) which correlates the digital samples of the composite signal with locally generated PRN code values to produce a plurality of (early, late), or (punctual, early-minus-late) correlation signals. Thus, during an initial acquisition mode, the delay spacing is relatively wide, on the order of approximately one PRN code chip time. However, once PRN code synchronism has been achieved, the code delay spacing is narrowed, to a fraction of a PRN code chip time. There are several advantages to this arrangement, especially in environments wherein multipath distortion in the received composite signal is of the same order of magnitude as a PRN code chip time.

Abstract: A method is disclosed for removing oxide from the surface of a semiconductor body having a thick oxide and an adjoining thin oxide, without subjecting the surface to significant over-etching and thus avoiding degradation of the surface of the semiconductor body. A photoresist layer is first deposited covering the thin oxide. The thick oxide is then etched for a period of time so that a portion of the thick oxide remains, and has a thickness comparable to that of the thin oxide. The photoresist layer covering the thin oxide is next removed without appreciably etching either the remaining portion of the thick oxide or the thin oxide. Finally, the thin oxide and the remaining portion of the thick oxide are removed, without appreciably over-etching the surface of the semiconductor body.

Abstract: A noise reducing circuit for electronic receiving instruments, such as telephone receivers (12) in headsets or handsets that are used in noisy locations, provides compensation of the set's receiver unit (11) to-error microphone (13) transfer function to enhance the noise reduction. A further circuit (15) provides pre-conditioning of the incoming voice signal to make the noise cancellation more effective. The tendency of these noise cancelling circuits to oscillate is substantially lessened by added circuitry which rapidly detects onset of oscillation and momentarily reduces the noise cancellation without interrupting the incoming speech path altogether.
