Abstract: Record position information is recorded in a lead-in area disposed on an innermost peripheral side of a disc. When a record commanding means for commanding a start of recording operation is operated while a reproducing operation of a reproducing means is being stopped, a recording head is moved to a blank area on the disc which is detected on the basis of the record position information recorded in the lead-in area and input data is recorded in the blank area. When the record commanding means for commanding a start of recording operation is operated while the reproducing operation of the reproducing means is being paused, the recording head is moved to a position of a signal which has been outputted when the recording operation has been paused and the input data is recorded from this position.

Abstract: In multiplexing a plurality of coded data, degrees of difficulty of coding of the data are measured (500V,500A), the coding rate for each of the data is decided (506) by allotting a certain target bit rate with a ratio of the each of the measured degrees of difficulty of coding so that the bit rate of the multiplexed data becomes equal to the target bit rate, the data is then coded (306V,306A) in response to the decided coding rates, and the coded data is multiplexed (312) before being outputted to a transmission line (210A) or recording medium (210B). Thus, the bit rate of the outputted data is always kept at the target value to improve the usage rate of the transmission line.

Abstract: The present invention relates to antennas. One of the problems which arises during the operation of a linear array antenna with electrical downtilt is that cross-polar radiation currents are generated. These cross-polar radiation currents, if at the same frequency as the operating band of the antenna, interfere with the required gain of the antenna. The present invention provides a solution to cross-polar radiation currents with an antenna assembly comprising first and second apertured ground planes 802, 808 with an antenna probe feed network printed upon a dielectric substrate supported therebetween, the array of radiating elements having different phase input feeds, wherein an outwardly extending ground plane flange 818 extends from one of the apertured ground planes. There is also provided a method of receiving and transmitting signals by means of a layered antenna of this construction.

Abstract: A method and apparatus for impregnating a porous substrate
with a solids-bearing saturant first introduces the saturant into the substrate
from a first side, and then introduces a displacement material into the
substrate from the first side. This displacement material forces at least some
of the saturant in the substrate farther into the substrate, away from the first
side. A wide variety of devices can be used for introducing the saturant and
the displacement material into the substrate, including pressure saturators,
converging chamber pressure saturators, roller coaters, blade coaters, and
the like. By pushing the saturant away from the first side with the
displacement material, the first side can be made more suitable for further
processing such as adhesive bonding.

Abstract: In a sludge drying process, the sludge is deposited as a thin layer upon a heated surface and brought to simmering temperature and allowed to dry until it reaches approx. 50% dry solids. It is then mixed with sludge which has been previously dried and reduced to at least 90 % dry solids. The resulting mixture has solids content at least 60 (preferably 65-70)% and a friable structure. This mixture is then subjected to a further drying process in which the sludge is deposited on a surface as a thin layer into and through which warm air is blown. The vapours emitted from the simmering process are cooled to about 85 degrees C and condensed, the residual gases then being supplied to a flame and oxidised. Claimed apparatus for the process has a thin-layer drier (1) with a dried sludge discharge (4)to the second stage mixer (7) input (8) and discharge (11) to the final stage blower-drier. The drier (14) comprises a vibrating sieve (16) through which hot air is blown from below by a jet (18) at a 200-240 degrees C.

Abstract: The laser optic includes at least two optic converter elements (8, 9, 22) arranged one after another in the radiation path, whereby at least one of the elements is traversed by a laser beam, and the laser beam is fanned out into several parallel partial beams in a plane vertically to a first axis.

Abstract: In a Fibre Channel Arbitrated Loop communications architecture
(40,45), dynamic loop sizing includes selectively bypassing operational device
ports (10,15,20,25,30,35) in the loop in order to minimize overhead associated
with loop size. In redundant systems with multiple loops, the system is
optimized by judicious distribution of the bypassed ports among the loops.
Redundancy is at no point reduced. By bypassing unused or unneeded ports off
of a loop, the round trip delay of the loop is appreciably shortened. By
minimizing the round trip delay, arbitration overhead and access latency is
reduced, and loop bandwidth and overall performance is improved. Dynamic load
sharing balances the load between the dual loops when using dual ported devices
on the loops. Dynamic load sharing is accomplished by bypassing a given subset
of devices off each loop to reduce round trip delay; monitoring traffic on the
loops; and controlling which devices are attached to which loop in order to
balance the load across the loops. Dynamic system configuration features
provide an optimized system configuration on a discretely continuous basis,
including implementing dynamic loop sizing, dynamic load sharing, and managing
the interconnection of multiple loops and controllers.

Abstract: A transmission for a four-wheel drive vehicle having a multi-speed
geartrain (42) and power transfer mechanism (44) incorporated into a common housing
assembly (45). The multi-speed geartrain includes a input shaft (46), a mainshaft (48), and a
plurality of constant-mesh gearsets arranged for selectively coupling the mainshaft (48)
to the input shaft (46) for driven rotation at various speed ratios. The mainshaft (48) can be
selectively coupled to the power transfer mechanism (44) for establishing two alternative
power transmission routes. In particular, a range shift mechanism (58) is provided for
establishing a high-range power transmission route and a low-range power
transmission route from the mainshaft (48) to the input of an interaxle differential (60). The
torque delivered to the interaxle differential (60) is split between the front (32) and rear (38)
drivelines to establish a full-time four-wheel drive mode. As an option, a transfer clutch (200) is
provided for automatically controlling slip and torque biasing between the outputs of
the interaxle differential (60). A lock-out clutch (184) is provided for
permitting the interaxle differential (60) to be locked for establishing a locked four-wheel
drive mode. As a further option, a mode clutch can be provided for permitting one
of the drivelines to be selectively disconnected from the transmission for establishing
a two-wheel drive mode.

Abstract: A dynamic method for optimizing interference levels
between multiple downlink beams (12a,12b,12c) transmitted
from a satellite (10) with a common frequency spectrum
causes the power level of at least one of the interfering
beams to be adjusted so as to produce desired interference
levels within the beams' respective ground target areas
(A,B,C). The beam power adjustments are preferably
accomplished by varying the drive levels of the high power
amplifiers (28A,28B,28C) on board the satellite, at least
one of which is initially operated at less than its maximum
rated power level. Single or multiple beam powers can be
adjusted, either up, down or some up and some down. Power
level adjustments are normally made in response to actual
beam power profiles not matching design standards, to
changing service priorities among the different beam target
areas, and to changing signal power requirements for the
different beams.
