Patent EP-1096729-A1 (EP)
Inventor: JOHNSON IAN
IPC: H04W28/04
Filed: 1999-10-28
Abstract: A method of communication between computing entities in a local area
network operating an CSMA protocol in an environment where reflections of
omni-directional transmissions from a plurality of objects cause multi-path fading
includes data packets being transmitted having a header at a first, lower data
rate, followed by transmission of payload data at a second, higher data rate.
Where the packets are not confirmed to be received, the packet is retransmitted a
predetermined number of times before the transmitting entity reduces the payload
data rate of the packet and retransmits the packet. If the retransmitted lower
payload data rate packet is not confirmed to be received within the predetermined
number of transmissions at the lower rate, the packet is dropped.

Abstract: A digital loudspeaker responsive to a binary digital audio signal received at an input
(26). The digital loudspeaker is manufactured as an integrated module comprising an
array of acoustic output transducers each with a diaphragm (20) including a conductive
layer arranged facing a further conductive layer across a gap. The conductive layers of
each transducer form a parallel plate capacitor so that a drive signal applied across the
capacitor induces electrostatic force between the capacitor plates, thereby driving the
diaphragm (20). The non-linear response of the diaphragms (20) is compensated for
by pulse shaping circuits (22) which are arranged adjacent the associated diaphragms
(20). The pulse shaping circuits (22) each receive a unary digital drive signal from an
encoder circuit (24) via tracks (28). The encoder circuit (24) serves to convert the
binary digital audio signal received at the input (26) into a large number of unary
digital drive signals, one for each of the output transducers. Using standard silicon
processing technology, the entire integrated loudspeaker module, including transducers
and drive circuitry, can be integrated onto a single silicon wafer, or two wafers
arranged facing each other. In this way, arrays of a thousand transducers or more can
be manufactured in a single integrated module of modest total area.

Abstract: A machine for drilling oil-holes in crankshafts and the corresponding procedure. It can be used to drill one, two or more crankshafts per cycle. Each crankshaft can revolve on its own axis. The unit described is mounted on a horizontally-faced rotary table with vertical rotating axis, to place the crankshafts at different angles to the Z axis of the machining module, maintaining the horizontal position of the longitudinal axes of the crankshafts. Facing the unit is the machining module, provided with two horizontal spindles, drill tool-holders, with their corresponding guide bushings and parallel to each other, one on top of the other, at the same distance as the two crankshafts. The module has movement in three co-ordinates: axis X (horizontal-transverse), Y (vertical ) and Z (horizontal-presenting tools). A fourth axis W, (with additional module and independent action), moves parallel to Z and carries the guide bushings. It is provided with an automatic changeover, (tool+bushing or just the bushing), incorporating simultaneously the pair of spindles.

Inventor: KAZAHAYA YUKIO
IPC: F04B27/18
Filed: 1999-06-16
Abstract: When thermal load becomes low, a passage 58 is
opened by a control valve 81, whereby the pressure
within a crankcase 8 is increased to reduce the
inclination angle of a swash plate 10. When the
inclination angle of the swash plate 10 becomes minimum,
the cross-sectional area of a second passage 57 is
reduced by the swash plate 10, whereby the pressure
within the crankcase 8 is prevented from being
decreased. On the other hand, when the pressure within
the crankcase 8 is increased, a refrigerant outlet
passage 39a is closed by a check valve 31 serving as a
discharge control valve. In view of the fact that the
differential pressure between the crankcase 8 and a
discharge chamber 12 is smaller and more stable than
that between a suction chamber 13 and the discharge
chamber 12, the compressor is constructed such that the
pressure from the crankcase 8 is caused to act on one
side of the check valve 31 serving as a discharge
control valve, while the pressure from the discharge
chamber 12 is caused to act on the other side of a
valve element 31 of the check valve 30, so that it is
possible to employ a spring having a relatively small
spring force as a spring 32 for urging the spool valve
31 in a valve-closing direction. As a result, even
when the pressure within the discharge chamber is
progressively lowered with decrease in the thermal load,
it is possible to keep the check valve 31 open until
the compressor enters the minimum piston stroke
condition (extremely low-load operating condition) in 
which the swash plate 10 reduces the passage area of
the first passage.
