Inventor: DEHARDE HORST
IPC: H02B1/14

Abstract: 2.1 Encapsulated medium voltage switchgears, filled with insulating gas, are being used increasingly because of their small dimensions and a minimal maintenance cost. There is now an endeavour to operate such switchgears conspicuously. Originating from the lever drives for relatively small and medium-size switchgears up to control rooms for centralised remote operation of large switchgears, the task exists of producing a simple remote control for a medium voltage switchgear. 2.2 The invention indicates a solution in which a frontplate 4 of the drive housing 1 is provided with a number of switch cylinders 5 corresponding to the number of switching apparatuses, the piston rods 21 of which switch cylinders 5 are in each case connected in a force- fitting manner via a coupling element 8, 9 to one of the switching shafts 2, and a hydraulic set 12-16, known per se, is inserted in the base 25 of the switch housing 21, which hydraulic set 12-16 is connected via pressure lines 7 to the switch cylinders 5. 2.3 Such a medium voltage switchgear can be used in a versatile manner, e.g. with ring-cable switches, with cable switches and a transformer switch, a high-voltage, high rupture capacity fuse being inserted in the transformer outlet. <IMAGE>

Abstract: Disclosed is a (4T-2R) SRAM cell and method which achieves a much reduced cell area through the combined use of vertical trench pull-down n-channel transistors and a buried-­layer ground plate. The reduced cell area allows the fabrication of a higher density SRAM for a given set of lithographic rules. The cell structure also allows the implementation of a (6T) SRAM cell with non-self-aligned poly-­silicon p-channel pull-up transistors without appreciably enlarging the cell area.

Abstract: In order to produce first and second Lee-error correcting code sequences in a multilevel quadrature amplitude modulator comprising a code converting unit (10) for converting first and second 2 m  -level input digital signals into first and second major converted signals by rearranging a square signal point arrangement into an approximately circular arrangement on a phase plane, each of the first and the second major converted signals consisting of m binary bits numbered from a first (least significant) bit through an m-th (most significant) bit, a first error correcting code producing circuit (21) carries out error correcting calculation for the first through an n-th bits of the first major converted signal to produce the first Lee-error correcting code sequence where n represents an integer (2 ≦ n ≦ m). Similarly, a second error correcting code producing circuit (22) produces the second Lee-error correcting code sequence. The first and the second major converted signals are multiplexed with the first and the second error correcting code sequences into a first and a second major multiplexed signal, respec­tively, which are then modulated into a multilevel quadrature amplitude modulated signal. In a counterpart multilevel   quadrature amplitude demodulator, an inverse operation is carried out to produce the first and the second input digital signals.

Abstract: Neuron architecture in which input analog data is applied in parallel to a plurality of neuron units (Fig. 2; Fig. 4 U1 to U5) in a time division manner. The analog input data is multiplied (3) by digital weight data which can be changed in accordance with the data of the interconnection between units. The product of the time division analog input data and the digital weight data are added in an integrator (4). While the sum of the products is output with regard to the present result, the previous sum of the product is output through a non-linear function forming means (6) simultaneously with the present data, thereby enabling operations for the sum of product in a neuron unit in an intermediate layer (e.g. U1, U2, U3) simultaneously with operations in a neuron unit in an output layer (e.g. U4, U5) and thereby providing outputs in a pipe-line manner. 
     When a first neuron unit (e.g. U1) in a layer produces an output (y1) on an analog bus (A), a second neuron unit (e.g. U2) in the same layer is able to produce an output (y2) such that the outputs (y1, y2, y3) of the first layer are produced on the output analog bus (A) in a time division manner. 
     An analog neuron unit or chip includes a plurality of operational amplifiers. The offset thereof is cancelled by offset cancelling means (8). 
     The above analog neuron unit may be used to provide an intermediate layer and an output layer, so that a neuron system is provided which operates in the form of a layered structure (Fig. 4). One layer comprising a plurality of neuron units (U1, U2, U3) can be repeatedly used by feeding back the output of one layer to the input of another layer to form a neuron system with a layered structure.

Abstract: A foreign matter detector includes an oscillator (1) coupled to an electromagnetic transducer (10) which includes an excitation coil (3) connected to the oscillator (1) and two interconnected detection coils (4,5) adapted to produce a differential signal therebetween when an object is passed through the transducer. A first detector (7A) produces an analog signal corresponding to the component of the differential signal in phase with the oscillating signal, and a second detector (7B) produces a second analog signal corresponding to the component of the differential signal in phase with a phase-shifted version of the oscillating signal. The analog signals are converted to digital signals. As the object passes the transducer, the output of the transducer changes in a first sense during a first part of the passage and in the opposite sense during the remaining part of the passage. A photosensor (50) generates a passage signal which lasts for one part of the object's passage through the transducer. The passage   signal is used to define the digital values of the two digital signals from which representative values X and Y are selected. These values are used in one or more discriminant equations to determine whether foreign matter has been detected. Coefficients for the discriminant equations are derived by passing sample objects through the detector. The coefficients can be stored, together with a code associated with the type of object being detected, for later retrieval.

Abstract: An optical shaft angle encoder has a plurality of active photodiodes (26) in an array on a semiconductor chip. A rotating code wheel (3) has alternating areas (13, 15) for alternately illuminating or not illuminating the active photodiodes (26) in response to the rotation of the wheel (3). Errors in the duty cycle involving the end active photodiodes (26) in the array are largely avoided by having a plurality of inactive photodiodes (27) at each end of the array with width and electrical properties effectively the same as the active photodiodes (26) so that leakage current to each end active photodiode (26) of the array is substantially equal to the leakage current to active photodiodes (26) remote from the end of the array. Similarly, leakage current which may affect the duty cycle of individual photodiodes (26) may be minimized by surrounding the individual photodiodes with a reverse biased photodiode junction.
