Abstract: For path selection in a multi-stage ATM switching matrix, the free transmission capacities of intermediate ATM lines are stored individually by means of an occupancy memory. For arranging new virtual circuits, a required transmission capacity is in each case signalled. Depending on the condition of the latter, path selection takes place only via intermediate ATM lines with instantaneously adequately free transmission capacity. Bit rate classes are formed to store the free transmission capacity. The required transmission capacities are also filed in these. Memory spaces assigned to each individual intermediate line are binary-coded in memory elements of the occupancy memory which are provided for each bit rate class, in each case for one intermediate ATM line group which is connected on the output side and/or on the input side to an ATM switching element, if transmission capacity is in each case still freely available according to the allocated bit rate class. During the path selection, the coincidence of the binary coding provided for the respective bit rate class is checked.

Abstract: A method is described for the controlled access to time-multiplex channels in a transmission system by means of tokens. The transmission system contains a multiplicity of stations which access a transmission path and one of which specifies a time frame. Some of the time slots of the time frame are used as fixed channels, others for the transmission of packets and the remainder as signalling channels. Before transmitting a packet, every station first transmits a token in a signalling channel and transmits the packet only after the undisturbed reception of said token in the signalling channel. The sequence in which the stations acquire access to the channels used for packet operation depends on a priority number contained in the token and on a packet length number specifying the length of the packet to be transmitted. Every station determines, from the data of the tokens contained in the signalling channels, the starting point for its own transmission in one of the subsequent time frames by taking the sum of all the packet lengths which are specified in the tokens which are in a token location situated in the time frame before its own. <IMAGE>

Abstract: An optical wavelength-converting device for generating the second-harmonic wave through Cerenkov radiation has a substrate (12) made from nonlinear optical crystal which acts as a cladding layer. Formed on the top surface of the substrate is a long, narrow waveguide layer (16), whose refractive index is larger than that of the substrate. In the substrate (12), multi-layered domain-inverted sections (14a, 14b, 14c) are formed. With this arrangement, the nonlinear optical coefficient is locally changed, there by compensating for phase mismatching between the fundamental wave and the second-harmonic wave in the direction perpendicular to the substrate's surface. This compensation helps improve the efficiency in converting the laser input light (18) of the fundamental wave into the second-harmonic wave (20).

Abstract: The object of the present invention is to provide a prime mover by which rotary force can be obtained only with magnetic actions of a magnet. The first rotary body provided with the second magnetic body can be driven and rotated as the second magnetic body is attracted by the first magnetic body attached to the inner circumferential face of the body base which is in a stationary state. And When the second magnetic body passes through a position confronted to the first magnetic body, the second magnetic body is covered up with the magnetic control member on the second rotary body which is driven and rotated under such a condition as the speed thereof is accelerated for the first rotary body by the first rotary body. As a result, the magnetic action of the first magnetic body is not exerted on the second magnetic body. 
     The above state is repeated by turns at each of the portions divided in the axial core direction of the prime mover, thereby causing the rotation of the prime mover to be maintained.

Abstract: A spread spectrum demodulator for use with a phase-shift-keying modulated spread spectrum signal used in mobile satellite communications. An objective of the spread spectrum demodulator is to perform tracking by producing from a correlation pulse signal an error signal having a time discrimination characteristic. The spread spectrum demodulator generates from the correlation pulse signal an error signal whose level varies in response to a phase difference between a pseudonoise signal contained in a received signal and a reference pseudonoise signal. A clock in synchronism with the received signal is generated from this error signal, thereby demodulating the received signal.

Abstract: An audio surround system particularly arranged for use in a theater provides the enhanced ambience and wide sound image advantages of a stereo enhancement system (SRS system) having directivity servos. A stereo enhancement system known as the "SRS" enhancement system enables a pair of relatively closely spaced speakers to provide a wide sound image lacking in any apparent point source and having enhanced directivity. A first SRS system (10) is modified for use with a set of front speakers (16, 22, 26) by increasing speed of its directivity servos, minimizing "pumping" caused by the increased directivity servo speed, increasing its threshold, and providing a bleed for minimizing reverberation effect. A similar SRS system (34) drives a set of rear speakers (40, 46, 50) and is differently modified to eliminate certain high pass filters, increase speed of its directivity servos, and to feed only ambience signals to left and right rear speakers (40, 46). Center sound, the sum signal from the rear SRS system (34), is fed to a sub-woofer (50).

Abstract: There is disclosed a timing system for use in a microprocessor for initiating microprocessor outputs onto an input sampling from an external bus in synchronism with a bus timing clock. The timing system is operative in a first mode for internally generating the bus timing clock and in a second mode for being driven from an externally generated bus timing clock. In the first mode, the timing system generates first and second inverse phase timing clocks responsive to an external clock source and independently generates the internally generated bus timing clock with the rising edges of the bus timing clock coinciding with the rising edges of the first microprocessor timing clock and the falling edges of the second microprocessor timing clock. In the second mode, the timing system generates the first and second microprocessor timing clocks in response to the externally generated bus timing clock. In both modes, the timing system initiates an output onto the bus upon the common assertion of the first microprocessor timing clock and the bus timing clock and initiates sampling of an input from the external bus upon the inverse assertion of the second microprocessor timing clock and the bus timing clock.
