Abstract: First and second independent optical fiber amplifiers, which preferably include first and second rare-earth doped optical fibers, respectively, are provided in a two-stage series or parallel configuration.      An optical divider for dividing and taking out pumping light to a side opposite where the pumping light is combined, is coupled to the first optical fiber. An optical combiner combines the divided pumping light with the second optical fiber from a side opposite to a pumping light source. The amplification efficiency is promoted by using the pumping light which has not been used in the one optical fiber amplifier by inputting it to the other, and vice versa. Preferably, wavelength filters block naturally emitting light to first and second optical combining and dividing instruments. Alternatively, wavelength filters block signal light in inputting the divided pumping light to the optical fiber amplifier on the other side.

Abstract: A seed treater for providing a uniform coating of liquid chemical or the like to seed prior to planting. Overflow of seed accumulated in an internal chamber causes seed to splash out of the chamber and fall through an annular space between the chamber and the housing as a dispersed annular curtain. A circular, hollow conical spray pattern from a centrally positioned nozzle intersects the annular curtain. The annular curtain passes through the spray pattern at an angle resulting in uniform coating of the seed. The seed falls through a conical discharge for recovery. Preferably a cone at the bottom of the chamber creates an annular gap through which seed can drain at the end of the operation.

Abstract: A selectively aspirating stylet assembly comprises a stylet having proximal and distal ends, the proximal end in fluid communication with a fluid supply and the distal end disposed at or near the end of a catheter, cannula or other generally tubular member that is to be inserted to a specified location within a patient's body, so as to create a fluid flow path from the fluid supply through the generally tubular member to the specified location. A valve assembly located within the fluid flow path is operable to close off a fluid column within the stylet assembly to facilitate placement of the tubular member within the body, and to control the flow of fluids within the assembly. Insertion o f the tubular member into the body is accomplished by placing a portion of the stylet within the tubul ar member, closing the valve assembly to create a closed fluid column; inserting the style/tubular member assembly into the body; and then, during the withdrawal of the stylet, opening or closing the valve assembly as necessary to control the flow of fluid within the style/tubular member assembly to avoid substantial aspiration of body fluid and tissue.

Abstract: There is disclosed a route finder apparatus and method for satisfying for point to multi-point connection requests in a communications network comprising a plurality of nodes connected by a plurality of links. A cost is assigned to each network link. For each connection request a set of all network nodes not included in its source node or its plurality of destination nodes are selected. An array of bits is created with an array element corresponding to a selected node element having a value of 1 if the node is Steiner vertex for a Steiner tree of nodes not selected, otherwise the array element has a value of 0. Each array is treated as a bit string and considered as population members which are manipulated by genetic algorithms. The fitness of the population members is evaluated by calculating the cost of traversing the routes represented by the bit strings.  The method is capable of routing a plurality of multi-point connection requests, and selecting an overall optimum solution.

Title: Simplified ink jet head

IPC: B41J2/16
Filed: 1995-03-17
Granted: 2003-02-18
Abstract: In the embodiments of the simplified ink jet head described in the specification, a carbon body is formed with ink passages, such as internal passages (19, 21, 25) extending through a carbon plate (26), pressure chambers (2) on one side of a carbon plate (26), flow-through passages (24) on the other side of the same plate and ink supply passages (19, 25), and a piezoelectric plate (23) is affixed to the pressure chamber side of the carbon plate by a thin layer of epoxy adhesive.  The piezoelectric plate (23) may have a conductive coating on one side which is photo-etched to produce an electrode pattern corresponding to the pattern of the pressure chambers in the carbon plate.  An orifice plate (13) may have specially profiled orifice openings (12) to assure axial projection of drops and may be affixed by a thin layer of epoxy adhesive to a carbon plate (26) having orifice passages (21) supplying ink from the pressure chambers (20) to the orifices (12).  Since the carbon plate is conductive, it can be used, if desired, as an electrode on the opposite side of the piezoelectric plate (23) and, to assure grounding of the piezoelectric plate, a conductive epoxy adhesive may be used to bond the piezoelectric plate to the carbon plate.  Moreover, since the carbon plate is porous, it can provide a communication path (76) between a vacuum source (77) and an air-permeable, ink-impermeable layer (75) on the ink passages to remove dissolved air from the ink in the passages.  In one alternative embodiment, an ink jet head assembly contains two separate carbon pressure chamber plates, a carbon manifold plate and a carbon collar to retain the carbon plates in an assembly.
