  • Patent number: 5778674
    Abstract: In a diesel engine in which boost air is supplied by a turbocharger, the generation of dry soot, which is a component of smoke, is suppressed by lowering the intake air temperature in the cylinder at the compression top dead center position of the piston. The fuel injected into the intake air is ignited by the heat of this compression. In order to reduce the intake air temperature at the top dead center position without reducing the amount of the intake air, the boost pressure of the turbocharger is lowered and also the effective compression ratio by the piston for the intake air is raised by, for example, altering the closing timing of an intake valve.

  • Patent number: 5781541
    Abstract: An arrangement (apparatus and method) for providing a code division multiple access (CDMA) transmission system in an urban environment using spatially-diverse antennas and time-diversity devices and techniques to provide improved cell coverage without the detrimental effects of multipath (Rayleigh) fading. The spatially-diverse antennas output identical CDMA-modulated signals to a serving area at different times, whereby each CDMA-modulated signal output from a corresponding antenna has a sufficent delay to avoid mutual interference with the identical CDMA-modulated signals output from other antennas. The delay assigned to each antenna is within a range greater than a chip interval, and less than or equal to a base station sequence offset between base stations. As a result, a subscriber station is able to separately demodulate the received CDMA-modulated signals from the different antennas as CDMA signals having adequate multipath delay for demodulation using a rake receiver.

  • Patent number: 5781620
    Abstract: The invention provides a method for automatically selecting a carrier network from a plurality of available networks to carry a telephone call (including MTS, video, data, etc.) for which toll charges are to be levied. The selection is made as a function of the call-type, and the method may be used, for example, to select a carrier, pre-subscribed to by a subscriber, for intra-LATA toll calls, inter-LATA and international calls. Alternatively, within a call-type, a carrier may be selected on the basis of toll rates, either on a per-call basis or by pre-subscription. A receiving end-office receiving a call from a calling station determines call-type and accesses a database whose contents either produce the identity of a preferred carrier for the call-type or the identity of the carrier having the lowest toll rate for the call. In any case, the identity of the carrier is returned from the database to the end-office and the end-office switch acts to connect the call to that carrier's network.

  • Patent number: 5777873
    Abstract: In a test system, test fixtures that hold modules are controlled to enable an operator to separate modules that pass a test from modules that fail. When a module under test is properly loaded in a test fixture, a test fixture controller instructs a tester to start a test procedure. For a semiautomatic test fixture, a test start command is automatically supplied to the tester when the test fixture is closed around the module under test. The test fixture controller automatically interprets the test results provided by the tester. The module that passes the test is automatically released from the test fixture. If the module fails, the test fixture controller keeps it locked in the test fixture. The module is released only when an operator presses a failure acknowledgement button on a control box.

  • Patent number: 5774393
    Abstract: A memory cell includes a read/write word line R/WL1 driving access transistor Q1 in read and write operations and a write word line WL1 driving access transistor Q2 in the write operation. In the write operation, both access transistors Q1 and Q2 are driven, and storage information is written in the memory cell by a bit line and a /bit line having potentials complementary to each other. On the other hand, in the read operation, only access transistor Q1 is rendered conductive, and storage information is read out through the bit line. Since access transistor Q2 is rendered non-conductive, a P type TFT transistor and an N type transistor operate as a CMOS type inverter having a large voltage gain. Therefore, a sufficient operating margin is secured even in the read operation.
