Abstract: A method and apparatus for demodulating includes differential-detecting an
input signal into which a unique word is inserted, correlating an output of the
differential-detection and a data table obtained by differential-detecting the unique
word, detecting a time when an electric power of a correlation output which exceeds a
threshold value becomes the local maximum, reading the input signal stored in a buffer
from the leading end of the unique word, estimating a frequency error of the input
signal based on a phase of the correlation output, obtaining a signal by removing the
frequency error from the read signal and inverse-modulating a unique word portion in
the signal in which the frequency error has been removed, according to a data of a
unique word table, and then reproducing a carrier signal.

Abstract: The invention provides a pellicle comprising a frame having one end surface and another end surface and a membrane extended over the frame on the one end surface side. A channel is formed in the other end surface of the frame. The channel is filled with a layer of a tackifier capable of expanding upon heating and/or light irradiation such that the tackifier layer does not protrude outward beyond the other end surface of the frame in an unexpanded state, but protrudes outward beyond the other end surface of the frame when expanded. No liner is attached to the tackifier layer.

Abstract: A fluid flow control mechanism for use in refrigerant circuit of vehicle has a compressor, a condenser, and an evaporator connected to each other in series. The fluid control mechanism includes a passageway control device having an actuating chamber therein and controlling to change the size of an opening of the inlet of the compressor in response to a pressure difference between the inlet of the compressor and the actuating chamber. A valve control device connects the actuating chamber of the passageway control device with the outlet of the compressor and the inlet of the compressor to minimize a pressure difference between the inlet of the compressor and the actuating chamber when the vehicle accelerates. The fluid flow control mechanism reduces the excessive load on the compressor caused by the vehicle accelerating while simultaneoulsy preventing torque shock when the compressor is started.

Abstract: Cette invention se rapporte à des procédés et à des appareils pour systèmes de radiocommunications mettant en oeuvre des mesures d'énergie (par exemple, d'intensité du signal). De façon à permettre l'exécution des mesures parallèlement au décodage et à la démodulation des signaux d'information, on peut fabriquer un double du signal reçu. Ce double peut être traité de manière à permettre la mesure sur n'importe quel canal souhaité. Diverses techniques d'accès telles que l'accès multiple par répartition en fréquence (AMRF), l'accès multiple par répartition dans le temps (AMRT) et l'accès multiple par différence de code (AMDC) sont envisagées. Les informations de mesure peuvent ensuite être transmises au système en vue de leur utilisation pour l'établissement du transfert. Les procédés de la présente invention permettent d'effectuer des mesures aux fins d'un transfert assisté par la station mobile (MAHO mobile assisted hand off) sans que les temps morts soient disponibles pour un récepteur et sans qu'un récepteur à exploration spécialisé soit utilisé uniquement pour les mesures.

Abstract: A method of sealing electronic parts mounted on the
substrates with a resin, by porous plate-printing, by
employing a primary porous plate-printing in which
sealing portions of an electronic part mounted on a
substrate are filled with a sealing resin through resin
push-in pores formed in the porous plate in vacuum by
reciprocally moving a squeeze, the resin is introduced
based on a pressure difference in vacuum of a degree
lower than that of the above vacuum state so that the
sealing resin infiltrates into every gap under the wires
bonding the lead wires of the substrate to the electronic
part, and supplementary sealing with the resin is
effected by a secondary porous plate-printing. Even
those portions in the structure of the electronic part
that cannot be easily filled with the sealing resin can
be filled with the sealing resin without forming air-containing
voids. Besides, such portions can be filled
without causing damage to the wires. The sealing with
the resin is effected maintaining flat surfaces of the
sealing resin, highly precise shape and size of the
resin-sealed structure, and offering highly improved
reliability for the resin-sealed electronic parts.

Abstract: A grinding wheel is for use in a grinding
machine, and is attached on a wheel spindle of the
grinding machine for simultaneously grinding at
least two parts of a workpiece. The grinding wheel
includes at least two wheel cores. Each of wheel
cores has a disk-like shape. An abrasive layer is
disposed on a circumferential surface of each of
the wheel cores. A spacer portion is inseparably

keeping a space between the abrasive layers of the
wheel cores. And a first labyrinth portion located
on one of side surfaces of one of the wheel cores
for forming a labyrinth seal with a second
labyrinth portion arranged on the grinding machine. 
     The number of separable parts of the grinding
wheel are extremely decreased in consideration of
imbalance of every part. The spacer portion is
integral with at least one of the wheel cores.
Since the grinding wheel is easily accurately
balanced, vibration of the grinding wheel is
decreased and stability is enhanced when the wheel
spindle is driven at very high speed. As a result,
machining accuracy for grinding is enhanced.

The apparatus includes a processor programmed to

the processor reduces the current cell rate of each
elastic connection and releases at least some non-elastic
connections such that the current cell rate of each
elastic connection is reduced and the non-elastic
connections are released until the total of the current
cell rates of the elastic connections and the equivalent
cell rates of the non-elastic connections have been
reduced by at least the bandwidth change amount. When the
bandwidth change amount is positive, the processor
increase the current cell rate of each elastic connection

Abstract: A method of injecting fuel in multicylinder engines. A fuel pre-pressure is generated to be converted within acceleration pipes by opening controlled shutoff valves and recirculating fuel to a fuel pump inlet. The fuel under pre-pressure is conveyed via a fuel pump into a pre-pressure common rail common to several engine cylinders. This pre-pressure is only a fraction of the required injection pressure. When the pre-pressure is exceeded, fuel is fed from the pre-pressure common rail, via pressure-limiting valves, into a return common rail common to several engine cylinders. The shutting off of the shutoff valves provokes a steep rise of fuel pressure, due to a water hammer effect. This produces a high-pressure wave since the closed shutoff valve supplies high pressure for fuel injection through the respective injection nozzle associated with the shutoff valve. One acceleration pipe is used for every shutoff valve between the pre-pressure common rail and the return common rail. At least one injection nozzle is actuated in the respective acceleration pipe per shutoff valve.
