Abstract: The reliability of transformer differential relays is enhanced by providing a method and apparatus which enable improved discrimination between transformer current differentials due to transformer inrush current and current differentials due the occurrence of an internal fault. This improvement in discrimination is provided by generating a first signal representative of currents flowing in at least two windings of the transformer, a second signal representative of a positive portion of the first signal, and a third signal representative of a negative portions of the first signal. A first output signal is generated when the magnitude of the second signal exceeds a first predetermined value, and a second output signal is generated when the magnitude of the third signal exceeds a second predetermined value. A trip signal is generated upon coincidence of the first and second output signals. Additional operate energy is generated when the magnitude of the absolute value of a vector sum operate signal, representative of the vector sum of currents flowing in at least two windings of the transformer, exceeds a first predetermined magnitude. The additional operate energy is terminated and additional restraint energy is generated when the magnitude of a percentage restraint signal, representative of the absolute values of currents flowing in a least two windings of the transformer, exceeds a second predetermined magnitude for a predetermined period of time.

Abstract: A first network sends a first message, uniquely identified as a sync message to a second network. The first network produces a first relative time of when the first message is transmitted. When the first network recognizes that the first message was sent, a second relative time is obtained to send a second message to the second network containing a real time of the first network of when the first message was sent. The second network produces a third relative time within the second network of when the first message is received. The real time of the first network contained in the second message is associated to the third relative time of the second network, thereby synchronizing the time of the second network to the time of the first network. Any skew of time associated with transmission protocols of the first and second network is thereby eliminated.

Abstract: A synchronizing system accomplishes synchronous reproduction for video and audio signals The number of unit audio data blocks to be put in one pack is set in such a way that the difference between the presentation start times for the stream of video data and the stream of audio data in one pack in a predetermined pack period becomes a predetermined value, and the pack carries positional information of the pack in the predetermined pack period to the pack. In a reproducing apparatus, the difference between presentation start times for video signals and audio signals in each pack is acquired by referring to positional information (AAU sequence number) in a stream of packs, transferred by the above transmission method, and at least one of the presentation start times for video signals and audio signals in the stream of packs is controlled so that the difference between the presentation start times coincides with the difference between the presentation start times corresponding to the positional information.

Abstract: A method of forming an artificial snow layer (3) is disclosed. Water content is added to to atmosphere (7) above a floor by a humidifying device (13), or water mist is added to the atmosphere (7) by a water-mist supplying device. The water content or the water mist is frost-frozen by a refrigerating device (6) incorporated at the floor, thus forming on the floor an accumulated frost layer as an artificial snow layer (3). A method of maintaining the formed artificial snow layer (3) is also disclosed. After the formation of the artificial snow layer (3), an atmosphere refrigerating device (12) is stopped or reduced in its operation so as to release the maintenance of the atmosphere below the freezing point.

Abstract: A high power, flip-chip microwave monolithic integrated circuit (MMIC) assembly (30) has a high power microwave monolithic integrated circuit (MMIC) having a surface with an active area (72) in which heat is generated. The assembly also has a host substrate (34). A thermally conductive bump (51) formed over the surface of the MMIC has a first portion (51') in close proximity to and in thermal communication with the active area (72) of the MMIC and a second portion (51'') which is in close proximity to and in thermal communication with the host substrate (34). The second portion (51'') of the thermal bump (51) has a greater cross-sectional area than the first portion (51'). A multi-layer, multi-exposure method of manufacturing the improved thermal bump (51) includes several steps. A plating membrane (80) is formed on a surface of the MMIC (32). A first layer of negative photoresist is applied to the surface of the plating membrane (80), and is exposed with a first masked pattern of light. A second layer of negative photoresist is applied on top of the first layer of photoresist. The second layer of negative photoresist is exposed with a second masked pattern of light. Unexposed areas of the first and second layers of photoresist form a "T" shape. The first and second layers of photoresist are developed with a photoresist developer, thereby leaving a "T"-shaped via in the photoresist. An electrically and thermally conductive metal is plated onto the plating membrane and into the via to form a substantially "T"-shaped bump (51), which is then attached to a host substrate. The resulting bump has greater cross-sectional area at the host substrate than at the MMIC (32).

Abstract: A communications adapter receives and transmits simultaneously packet and/or isochronous data between two interfaces; a network and a host bus system. The adapter stores the isochronous and packet data in receive and transmit queues configured in a FDDI RAM buffer. A controller manages the transfers of the data into and out of the queues. A local bus interacts with the system to provide descriptors of addresses in the system for transfers of data out of the queues to the system or the network. The controller is programmable to provide a variable threshold for the transfer of data between the queues and the system or the network. A systems interface unit handles the transfer of data to/from the system and allows data to bypass the queues and directly access the system or the network.
