Patent EP-0761981-A2 (EP)
Inventor: HARADA HIDEOMI
IPC: F04D29/46
Filed: 1996-09-09
Abstract: An impeller-driven turbomachinery for use in centrifugal and mixed flow pump overcomes operational difficulties, such as flow separation and generation of surge at low flow rates, often encountered in similar machines of the conventional design. The turbomachinery is provided with variable-angle inlet guide vane and variable-angle diffuser vanes, and the diffuser section is constructed according to a fluid dynamic principle, and the vanes having a wing shape are distributed tangentially so that the diffuser section acts as a centrifugal diffuser. A convenient operational parameter, chosen from such variables as input current to drive motor, rotational speed or torque of the drive motor, inlet/exit pressures, and fluid velocity, is monitored during the operation by means of sensors strategically attached to parts of the operating system. Real time changes in the operating parameter is measured and the setting angle of the inlet guide vane is adjusted in accordance with a predetermined relation between inlet flow volume rates and flow angle of the fluid exiting from the impeller so as to maintain the fluctuations in the monitored operating parameter below a threshold value. If the targeted head value is not produced under this adjustment, the setting angle of the diffuser vanes can also be adjusted based on real time measurements of other operational parameters. If this adjustment fails to produce the targeted head value, then the rotational speed of the impeller can be adjusted to operate the system while avoiding surge and other problems encountered at flow rates. The proposed turbomachinery and method of operations are highly cost-effective because the control methodology is based on theoretical analysis of the flow pattern which is verified by trials, and it is not necessary to determine the operating characteristics of each production lot of fluid machines, thus saving the cost of software development for different machines.

Abstract: In an image-forming device, a toner image can be formed on a recording element (2) on the condition that a control grid (7) always keeps the repulsing force constant to the toner (T). As a result, the control grid (7) is kept free from clogging of its openings with toner particles. 
     While toner (T) on a toner carrier (5) is charged with negative polarity an attracted by applying positive voltage to a backing electrode (8) placed at the back of a transfer belt (2), voltage applied across the electrodes arranged crosswise in directions X and Y of the control grid (7) disposed between the transfer belt (2) and the toner (T) is changed so as to vary the toner repulsing force in space-charged openings of the control grid (7), thereby regulating the amount of toner (T) passing therethrough.

Abstract: A home network architecture has an internal digital network interconnecting devices in the home. Entertainment services are introduced into the network through network interface units that are coupled to an external network and to internal network. The network interface units are selectively directly connected by a direct circuit crossbar to set-top electronics so that video data, for example, may be directly provided from a network interface unit to the set-top electronics without jitter. A passive hub, which does not have packet routing capability, is then used to provide signal regeneration and re-transmission of other data over the network.

The beam forming network includes multiple beam ports (16) which receive as inputs composite beam signals. The beam forming network includes feed ports (18) as outputs which deliver feed signals to the feed array (20). The beam forming network (14) includes a divider circuit trace (48) and a combiner circuit trace (46) aligned along substantially parallel planes. Combiners (111-117) within the combiner circuit trace (46) are arranged in clusters (92), such that each combiner (111-117) within a cluster (92) operates in conjunction with a common feed signal.

Abstract: An enhanced compiler for compiling C++ programs without the use of forward declarations normally included in program header files. Through multiple parsing passes, the compiler extracts definitions for the declarations directly from the bodies of the C++ files. By saving the definitions to a persistent program representation, for example a program database, on subsequent sweeps, only definitions for new or changed declarations need be updated. In this way, C++ programs can be incrementally compiled on a declaration by declaration basis.

Abstract: The disclosed invention comprises a two step process for
forming the tip of a catheter. In the first process a
tapered catheter tip is molded by placing a tubular
catheter over a mandrel and inserting the mandrel and
catheter assembly into a mold having an inner mold
surface. The molded catheter with flash is thereafter
removed from the mold and the mandrel removed from the
catheter. The catheter and flash are inserted into a jig
which defines an opening through which the flash extends.
The opening is defined by a cutting surface and the flash
extends above such cutting surface. A cutter is then
moved along the cutting surface in order to severe the
flash at precisely the appropriate point along the
catheter length to leave a formed trimmed catheter. The
catheter is thereafter removed from the jig for further
processing.

Abstract: In a system (100), such as a video-on-demand-server, a reader (180) reads data from a storage medium (110) and stores the read data in buffers (125). The data is supplied from the buffers (125) to users (130) for consumption in the form of a plurality of data streams. The data streams may be fixed rate or variable rate with an identical maximum consumption rate of Rmax data elements per second. The reader (180) is controlled by a scheduler (170). The scheduler (170) divides a predetermined period of tcycle seconds, wherein for each active data stream at least Rmax*tcycle data elements can be read from the storage medium, into n successive time intervals, each of t¿interval? seconds. For each data stream a corresponding buffer (125) is reserved for storing at least Rmax*(n+1)*t¿interval? data elements. The data is read from the storage medium (110) by repeatedly sweeping the storage medium (110) for a group of data streams. Immediately before causing the reader (180) to perform a next sweep, the scheduler (170) determines the composition of the next group of data streams to be supplied with data. At least data streams whose corresponding buffer (125) comprise less than Rmax*2*t¿interval? data elements are assigned to this group.

Abstract: A metal V-belt type continuously variable transmission in which the length (L) of a side of an
element contacting with a V-face of a pulley is shortened to increase a ratio range.
The angle of the V-face of the pulley is
represented by (α), and the hertz surface pressure between the pulley and the metal element is
represented by (σ H ), the following relation is established:  L ∝ sin α/σ H   2   . When the hertz surface
pressure (σ H ) is determined to be between an upper limit value defined by the wear durability of the
metal element and a lower limit value defined by the limit tensile force of an endless belt, the
element side length (L) can be decreased by decreasing the angle (α) of the V-face of the pulley. Thus,
the distance through which the metal element can be moved radially of the pulley is increased to
increase the ratio range.
