Abstract: A butterfly valve for hot fluid, including: a cylindrical duct (2); a flap (3) pivotally
mounted inside said duct; a shaft (4) attached to said flap so that a rotational torque can be
transmitted to the flap; a pin (5) inserted into a peripheral portion of said flap so that the

is fully opened. In the butterfly valve a driving force for opening and shutting does not
change, and the butterfly valve smoothly opens and shuts even in use for a long period
of time in a hot gas flow even in the case that the use of the valve at a high temperature
causes an adhesion of oxidized scales or an increase of a coefficient of friction between
members.

Abstract: A fuel vapor treating mechanism (30) includes a canister
(31) for adsorbing fuel vapor produced in a fuel feed system.
The treating mechanism (30) purges the fuel vapor adsorbed by
the canister (31), along with air, to an intake system of the
engine (10). An ECU (40) computes a value representing the
flow rate of the purged gas as a value that represents the
capability of the treating apparatus. The ECU (40) sets a
decision value in accordance with the amount of the fuel vapor
produced in the fuel feed system. The decision value
represents a required capability of the treating mechanism
(30) . When the value representing the capability is less than
the decision value, the ECU (40) prohibits stratified charge
combustion and causes the engine (10) to perform homogeneous
charge combustion. Therefore, as many opportunities as
possible are provided to perform stratified charge combustion,
which improves fuel efficiency.

durch eine vom Fahrer über eine Bedieneinrichtung, insbesondere einen

Die Erfindung zeichnet sich dadurch aus, daß die Schwenkbewegung des Entriegelungshebels (1,1')
nicht auf den Bowdenzug (8) übertragen wird, da sich der Entriegelungshebel
entlang einer in ihm eingehängten Bowdenzuglitze (4) bewegen kann, weil
ein Formschluß zwischen Bowdenzuglitze und Entriegelungshebel über eine Verdickung (5)

Abstract: A receiver includes inversely spreading circuit
(12), a RAKE synthesizing circuit (13), a noise
measuring circuit (15), a weighting circuit (16) and a
decoder (14). The inversely spreading circuit
inversely spreads a reception signal for every path
using a spreading code to produce path data signals
for paths. The RAKE synthesizing circuit synthesizes
the path data signals to output a RAKE synthesis
signal while carrying out a weighting operation for
every path such that the RAKE synthesis signal has a
maximum S/N ratio. The noise measuring circuit
measures a noise level of each of the path data
signals, and calculates a total noise amount for the
paths from the measured noise levels. The weighting
circuit carries out a weighting operation of the RAKE
synthesis signal based on the total noise amount to
produce a weighted signal such that a time change of
distortion in the RAKE synthesis signal is cancelled.
The decoder decodes the weighted signal to produce an
information sequence.

Abstract: A stratified charge is formed in an engine by injecting
fuel at an impingement surface (70) adjacent an outlet (38)
of an injector (32). The injected fuel thereby forms a
cloud shallowly penetrating the combustion chamber (24) so
as to float therein to reduce wall-wetting and subsequent
soot formation. A substantially flat top piston (16) urges
the cloud upwardly during a compression stroke of the
engine. The cloud remains substantially unmixed with the
inducted air, thereby producing the stratified charge. The
continued motion of the piston (16) causes the cloud to move
toward the spark plug (30) for ignition.

Abstract: A classification application utilizing a table of
connection numbers and associated TCP/IP applications is
utilized for determining a wireless packet communication,
quality of service level by decoding a connection number
field of the compressed packet header. Packets carrying
different connection numbers can be mapped to different
Quality of Service planes. When a non-active TCP connection
becomes active, the classification application detects and
identifies the connection by reading the connection number
field of a compressed TCP/IP header in a packet of the
application. The classification application applies the
appropriate Quality of Service level as determined from a
user database and a list of available Quality of Service
levels. If the connection has no table entry, the TCP/IP
application is identified based on comparison to a pre-loaded
table of port numbers and a new entry is created in
the connection number table.

Abstract: A magnetic position sensor for sensing the position of a
foot pedal in a motor vehicle and producing an electrical
signal representative of the foot pedal position. The
position sensor has a stator 7 with a channel 17 and a
magnet 8 which can move along the surface 7a of the
stator, the magnetic field in the stator channel 17 being
dependent on the position of the magnet 8 relative to the
stator 17. The magnet is connected to the foot pedal so
that the movement of the foot pedal causes the magnet 8
to move along the stator surface and changes the magnetic
field in the channel 17, the magnetic field in the channel
17 being sensed by a Hall probe 6 which produces an
electrical signal proportional to the displacement of the
magnet 8.
