Title: Microcomputer FSK modulator
Inventor: MIZUNO TAKASHI
IPC: B60R16/023
Filed: 1995-09-13
Abstract: A microcomputer includes therein an operation control part which can be operated when a clock signal is applied thereto by an oscillation circuit. If the operation control part reads out an identification code from an EEPROM, then it switches a control signal to be given to a switching element in accordance with the levels of the respective bits. When the control signal is off, the oscillation frequency of the oscillation circuit is F1. On the other hand, if the control signal is turned on, then one terminal of a capacitor is grounded to thereby switch the oscillation frequency over to F1. The clock signal is divided by a frequency dividing circuit into m parts before it is output. The frequency of the output signal after divided becomes f1 or f2 in accordance with the above switching and the output signal is transmitted in the form of a frequency modulation signal.

Abstract: The present invention relates to a microwave strip line filter having a pair of dielectric substrates stacked and bonded to each other. In order to overcome that an electric characteristic of the filter may be varied due to any displacement of the relative position of resonant electrodes which may occur at a change of temperature during when the dielectric substrates are stacked to each other, the resonant electrodes (11, 12, 13) on one (10) of the dielectric substrates are formed to have a pattern of predetermined dimensions, and the resonant electrodes (21, 22, 23) on the other dielectric substrate (20) are formed to have a pattern which is similar to said pattern but smaller than said predetermined dimensions. 
     In order to prevent the electric characteristic from being adversely affected by bonding agent when the dielectric substrates are superimposed and bonded to each other, the dielectric substrates are bonded to each other by applying the bonding agent (26) to the resonant electrodes (21, 22, 23) on one of the dielectric substrates (10 and 20). 
     Further, in the present invention, a pair of dielectric substrates are made of ceramic materials having relative dielectric constants in order to easily and exactly obtain various desirable resonant frequency characteristics by using resonant electrodes having same pattern.

Abstract: An aliasing sampler probe (22, Fig. 1) for detecting plasma RF voltage and current employs a sampling signal with a sampling rate slower that the RF fundamental frequency selected to produce an aliasing waveform at an aliasing frequency that is several orders of magnitude below the RF fundamental frequency. In one embodiment, the RF power is applied at 13.56 MHz (Fig. 3A), and sampling pulses have a sampling rate of 2.732 MHz (Fig. 3B) to produce replicas of the RF voltage and current waveforms (Fig. 4) at an aliasing frequency of about 100 KHz. The aliasing replicas preserve phase and harmonic information with an accuracy that is not available from other sampling techniques.

Abstract: A method of storing video programs (M 1 , M 2 , M 3 , M 4 , M 5 -M 22 ), such as movies, for video-on-demand access includes forming a hierarchy (H 1 , H 2 , H 3 , C 1 , C 2 , C 3 ) for the movies based upon anticipated frequencies of access. Typically, more than one magnetic disk (16; 40, 42, 44, 46, 48 and 50) is used to store the video programs, with each disk being partitioned into concentric annular zones (18, 20, 22, 24, 26, 28, 30, 32, 34, 36 and 38). In one embodiment, there is a direct correspondence between the hierarchy and the assignment of video programs to the annular zones. The movies that are anticipated to have the highest frequency of video-on-demand access are placed in the radially outermost zone until it is filled. The next highest video program is then recorded in the next zone. This pattern is followed until the radially innermost zone is filled. In a second embodiment, the same pattern is followed, but with the movies within the outer zones being strategically located within those zones in order to potentially reduce seek time. In a third embodiment, the highest rated video program in the hierarchy is located in a zone somewhat inwardly from the radially outermost zone, again attempting to provide a grouping that reduces seek time. In a last embodiment, the highest rated video programs in the hierarchy are recorded in the outermost zone, but the remaining video programs are recorded in a random fashion. This last embodiment trades some of the high bandwidth benefit at outer zones for the benefit of ease of implementation.

Abstract: The proposed invention deals with pulp and paper production, in
particular, with the process for preparing pulp cooking liquors to
manufacture a fibrous semifabricate. 
     A cooking liquor is proposed to be prepared by saturation of a water
medium with sulfurous anhydride provided that this water medium is in fact
either a pulp and paper mill waste water with activated sludge (18-40g/l) and
soda ash (1,55-2,50% by weight) in it or alkali hydrolyzate produced in
treatment of the same waste water by a mixture of base salts containing
sodium carbonate (50-90% by weight based on Na 2 O) at the temperature 25-40°C
followed up with a solid sediment removal and the saturation goes on
until sulfurous anhydride concentration in the liquor is 2,5-5,5% by weight. 
     The proposed method allows to increase considerably the output of a
fibrous semi-fabricate and improve its mechanical characteristics not to
speak of utilizing waste water generated at a waste water treatment plant of
a pulp and paper mill and expanding a sources of raw materials needed for

Abstract: Method and apparatus providing connection-oriented services for packet switched data communications networks. Directory services include distributed discovery of MAC addresses and protocol alias addresses. Topology services include a link state topology exchange among switches, which provides each switch with a complete topology graph of the network. This enables an access switch receiving a data packet to determine a complete path from a source end system to a destination end system. Another service includes resolution of broadcast frames to unicast frames, in order to reduce the amount of broadcast traffic. Policy restrictions may be applied prior to connection setup. Path determination services enable multiple paths from a source to a destination. Connection management includes source routed mapping of connections on the desired path. A distributed call rerouting service is provided wherein if a link on an active path fails, each switch receives a topology change notification and unmaps any connection involving the failed link. A broadcast/unknown service provides restricted flooding of nonresolvable packets. Furthermore, connection-oriented switching is provided based on the source and destination MAC addresses as a connection identifier. Still further, resolution of networks outside the switch domain is enabled by access switches listening for network and server route advertisements and maintaining best routes to said networks and servers. The best route metrics may be combined with best path metrics to determine a path from a first access switch to an egress switch connected to the external network.
