Inventor: FUJII YOSHIHARU
IPC: B41J13/00
Filed: 1990-11-20
Granted: 1999-06-08
Abstract: An image processing device prints a maximum possible number of frames of an original image on one or more printing materials. A CPU develops the frame and printing material information stored in the memory area so that a maximum number of possible frames can be placed within the printing material by selecting the layout and magnifying/reducing the frames. By switching the alternative print material according to a previously determined priority, the printing operation is continued without any interruption, even if the printing material initially selected runs out during the printing. The boundaries between frames are drawn by lines for convenience to separate each frame after printing.

Granted: 2000-08-15
Abstract: A bushing for mounting an overload protector within an opening in a motor shell comprises segments adapted to be coaxially positioned around a portion of the overload protector. Mating features formed on the segments and protector restrict movement of the protector relative to the segments. Grooves formed on the segments secure the segments within the opening and restricts movement of the bushing and protector assembly relative to the structure. The bushing preferably comprises a pair of generally symmetrical segments connected together by an integrally formed hinge. The one-piece bushing is molded from a thermoplastic material, such as nylon. In one embodiment, the features which restrict axial movements of the overload protector relative to the segments era mating threads formed on a portion of the internal surfaces of the segments, and on opposing portions of the external surface of the protector. An additional structure is formed on the exterior surface of the segments to prevent rotational movement of the protector relative to the bushing. In an alternative embodiment, a structures is formed on and extends from the segments, and at least partially surrounds the overload protector to secure the protector against opposing portions of the bushing. A portion of each of the segments extends outwardly from the exterior surface of the motor shall so as to shield an exposed and portion of the overload protector from damage. A gasket may be mounted to this portion of the bushing to prefect the overload assembly from dust and contamination.

Title: Real-time network routing
Inventor: ASH GERALD R
IPC: H04Q3/00
Filed: 1991-02-20
Granted: 1993-10-12
Abstract: REAL-TIME NETWORK ROUTING Abstract An arrangement for routing calls from a source switch to a destination switch in a telecommunications network. If a direct trunk is available between the two switches, that trunk is used. Otherwise, the destination switch is queried to obtain availability data of trunks to that switch from intermediate switches of the network. This availability data is then compared with availability data of trunks from the source switch to the intermediate switches. A route is then selected using an intermediate switch having available trunks from the source switch and to thedestination switch. If a route using lightly loaded trunk groups is available, that route is selected in preference to the use of a route using more heavily loaded trunk groups. Advantageously, routing is performed to dynamically optimize selection of a route based on the current state of the network. In order to ensure that different types of services carried over a trunk group receive equitable treatment, a load objective is specified for each type of service. If the actual load for a particular type of service equals or exceeds the load objective, then an available trunk of the trunk group will only be seized if thenumber of available trunks exceeds a reserve limit, the reserve limit being the sum of the differences between actual load and objective load for services whose actual load is less than the objective load as limited by a reserve limit for each kind of service. To give further protection to selected key services, an available trunk of a group can only be seized for use with a basic service if the number of available trunks exceeds the number being reserved for key services.

Title: A hybrid balance and combination codec filter circuit
Inventor: NASEER ABSAR
IPC: H04M3/00
Filed: 1991-05-15
Granted: 1999-01-26
Abstract: A hybrid balance and combination codec filter circuit used in a subscriber line interface circuit over which a connection is established between a digital switching network and a subscriber instrument.  The hybrid balance and combination codec filter circuit in combination includes a transmit section that converts differential voltage audio signals representing voice transmissions transmitted from the subscriber instrument into Pulse Code Modulated (PCM) encoded digital data, for transmission to the digital switching network.  A receive section converts PCM encoded digital data representing voice signals switched through the digital switching network into differential voltage audio signals for transmission to the subscriber instrument.  An included hybrid balance and echo cancellation section connected between the transmit section and the receive section reshapes the audio band signals output by the receive section.  The reshaped audio band signals are applied to the transmit section, where they cancel any reflected audio band signals not completely transferred to the terminating impedance. Finally, an impedance section provides an audio band feedback signal between the transmit section and the receive section for synthesizing a source impedance that is matched to the impedance of the tip and ring leads of the subscriber loop.

Abstract: A surgical tissue bag for percutaneously debulking large volumes of tissue contained within the bag. The tissue bag comprises two layers of material, an inner layer of a puncture-resistant material and an outer layer of moisture-proof material for containing cells and fluid therein. The bag material is foldable and flexible for insertion through an access sheath into the surgical site and for forming a gas-tight seal when extended through the access sheath or puncture site. A drawstring is attached to the open end of the bag to close the bag when the tissue is contained therein and pulled through the puncture site in the outer surface of the skin. After the closed open end of the bag is pulled through the puncture site, the closed end is fanned out against the outer layer of the skin, and a morcellator is inserted into the bag for debulking the large volume of tissue. The open end of the bag is continually fanned out to maintain a compact and tight containment of the tissue and fluid remaining in the bag. The morcellation process is continued until the entire volume of tissue is removed at which time the remaining portion of the bag is completely removed from the surgical site area.

Granted: 1996-06-11
Abstract: A   method   for   continuously   purifying   a polysaccharide  comprises  the  steps  of  continuously  and simultaneously   feeding   an aqueous   solution   of   a polysaccharide  and  a  hydrophilic  organic  solvent  which does not solubilize the polysaccharide,  mixing these two kinds of liquids with a rotary turbine to precipitate the polysaccharide,  cutting  the  precipitated  polysaccharide with  an  interlocking  cutter  which  comprises  a  fixed cutter and a rotary cutter,  and continuously withdrawing a suspension of finely cut polysaccharide particles.  The resulting polysaccharide  is not  in the form of strings, but in the form of fine particles and thus it is never adhered  to  an  apparatus  for  purification  and  does  not cause any retention within the apparatus. The particulate polysaccharides   obtained   by   the   method   are   easily separated from the resulting suspension and dehydrated.

Title: Frequency synthesis using frequency controlled carrier modulated with pll feedback signal
Inventor: ICHIHARA MASAKI
IPC: H03L7/18
Filed: 1992-10-26
Granted: 1998-10-27
Abstract: In a frequency synthesizer, a phase detector receives an externally-generated reference clock signal of a constant frequency and a feedback signal to produce an error signal, which is output through a loop filter to a voltage-controlled oscillator (VCO). A direct digital synthesizer (DDS) receives the reference clock signal and externally-generated phase data to produce a DDS output signal whose frequency is precisely controlled by the phase data. The DDS output signal is applied as a carrier to a differential detector where it is modulated with the output of the VCO to produce a signal corresponding to the lower sideband of the modulated carrier. The output of the differential detector is output to the phase detector as the feedback signal.

Granted: 2003-12-09
Abstract: A ATM switching arrangement is disclosed in which two types of cells are distinguished. A first type of cells is marked as low loss and a second type of cells is marked as low delay. In the switching arrangement a cell buffer (9) is subdivided into a first memory area (LL) for the low loss cells and a second area (LD) for the low delay cells. In the case of the cell buffer (9) being completely filled, low loss cells get read-in priority over low delay cells.  In reading out from the cell buffer low delay cells take priority over low loss cells, unless the low delay area is empty. It is also possible to set a threshold value for the content of the low loss area; when the content of the low loss area exceeds the threshold value, outputting of the low loss cells can then be started.

Abstract: A fluid rotor is disclosed for turning electrical generators or other mechanical equipment. The fluid rotor contains multiple curved blades which are in a single plane of rotation, and which are spaced closely together so as to maximize the efficiency of the captured fluid. The open blades are designed to overlap one another to an extent that there are always at least two blades positioned to capture the fluid regardless from which direction the fluid is flowing. The curved blades allow the rotor to always rotate in the correct direction regardless of the direction of the fluid without the use of moving vanes or housings to help direct the fluid at certain portions of the fluid rotor. If the rotor is made to turn in the incorrect direction, it will, as fluid from any direction flows against it, slow down, stop momentarily, and then begin to rotate in the correct direction.
