IPC: G11B20/14
Filed: 1989-07-20
Abstract: A digital phase locked loop circuit produces a reference waveform synchronized with a sequence of read data signals by dividing the reference waveform which consists of 0's and 1's windows, into early and late regions for determining the occurrence of a read data pulse within a window. The occurence of a data pulse during an early or a late region produces a corresponding phase error signal. The phase error signal controls the frequency of the reference signal by increasing or decreasing the periods of the early or late regions to synchronize the reference signal with the sequence of read data signals. A period table is addressed by a combination of reference signal timing and a frequency register whose output is modulated over several cycles.

Abstract: A wholly integrated, multistage, CMOS voltage multiplier utilizes as a diode structure for transferring electric charge from an input node to an output node of each stage an enhancement type MOS transistor, the gate of which is coupled to the same switching phase to which the output capacitor of the stage is connected by means of a coupling capacitor. During a semicycle of charge transfer through said MOS transistor, the coupling capacitor charges through a second MOS transistor of the same type and having the same threshold of said charge transfer MOS transistor, connected in a diode configuration between the output node of the stage and the gate of the charge transfer MOS transistor, in order to cut-off the latter when reaching a voltage lower than the voltage reached by the output node by a value equal to the threshold value of said second transistor. In this way, a significant voltage drop across the charge transfer transistor is efficiently eliminated, thus allowing the generation of a sufficiently high output voltage though having available a relatively low supply voltage.

Abstract: In a method for receiver-end bit detection of differentially encoded binary or quaternary PSK signals for differential coherent demodulation, received processed signals (yn) are first supplied in parallel to L symbol detectors of the order j (j=1, 2, 3..L; (L>1)). The complex conjugate signals (y<*>n-1, y<*>n-2,... Y<*><H N=0>n-L) delayed by j symbol periods and the unmodified processed input signals (yn) are multiplied to form non-quantised output values zn<(j)> of the L symbol detectors in multiplication components and subsequently complex-conjugated. Previously detected and regenerated PSK symbols (@n-1, @n-2,... @n-L+1), which are delayed by timing components, are then fed back accordingly, whence a symbol (an) is determined, for which the sum of the square intervals (¦zn<(j)>-an@n-1@n-2.... @n-j+1¦<2>) where j = 2, 3,... L of the L symbol detectors assumes a minimum value.

Abstract: An apparatus is described for classifying particles (30) and includes an optical system for transmitting to a focal plane which includes at least one particle (30), two substantially parallel optical beams (22, 24), the beams (22, 24) being initially mutually coherent but of different polarizations. The beams (22, 24) are displaced and focused in the focal plane. A further optical system is positioned in the path which the beam takes after departing from the focal plane and combines the beams so that a particle-induced phase shift in one beam is manifest by a change in elliptical polarization of the combined beams. A first detector (52) is responsive to the beam's intensity along a first polarization axis to produce a first output and a second detector (54) is responsive to the beams intensity along a second polarization axis to produce a second output. The first and second outputs are added (56) to provide an extinction signal and, in a separate device (218), are subtracted to provide a phase shift signal. The extinction signal and phase shift signal are both fed to a processor (60) which classifies a particle in accordance therewith.

Abstract: A thin film deposition method consists of depositing a thin film on a wafer by supplying a reactant gas molecules toward and onto the wafer within a vacuum vessel or chamber. 
     The pressure within the vacuum vessel is set to the pressure under which the mean free path (d) of the molecules contained in the supplied reactant gas can be longer than the shortest distance (L) between the wafer and the wall of the vacuum vessel exposed to the vacuum side, or d > L. 
     The temperature of the wafer is set to the temperature (T sub) at which the reactant gas can cause substantially the thermally decomposing reaction. 
     The temperature of the vacuum side-exposed wall of the vacuum vessel (T wall) is set to a temperature range having the lower limit higher than the temperature (T vap) at which the saturated vapor pressure can be maintained to be equal to the partial pressure of the molecules contained in the reactant gas, and having the upper limit lower than the temperature of the wafer (T sub), or T vap < T wall < T sub.

Abstract: A multidimensional systolic array processor uses a multidimensional array of systolically coupled processing elements to perform matrix-vector multiplication of matrix and vector signal sets. A two-dimensional array uses a PxQ matrix (P rows and Q columns) of processing elements which are coupled to systolically process the signals, e.g. via multiplication and accumulation. The processing elements are coupled both row-to-row and column-to-column for pipeline processing within each row and each column, i.e. multidimensional pipelining, thereby increasing processing parallelism and speed. Interconnectivity of the processing elements is minimized by forming separate column and row signal subsets of the vector signal set which are coupled simultaneously to each processing element in the first row and first column, respectively. Size of the processing elements is minimized by reducing local storage of matrix signal subsets within each processing element. Separate column and row signal subsets of the matrix signal set are formed and coupled into each processing element of the first row and first column, respectively. As the matrix column and row signal subsets are systolically processed and transferred row-to-row and column-to-column, respectively, each signal subset is reduced in size by one signal, thereby requiring the transfer and temporary local storage of successively smaller matrix signal subsets. A three-dimensional processor uses a PxQxT array (T planes of P rows and Q columns) of processing elements which are coupled plane-to-plane-to-plane.
