Abstract: This invention relates to a process for making gel-free functionalized polymers. When multi-lithium initiators are used to make these polymers anionically, the process comprises anionically polymerizing at least one monomer with a multi-lithium initiator in a hydrocarbon solvent, functionalizing the polymer by adding to the polymer a capping agent that reacts with the ends of the polymer chains such that strongly-associating chain ends are formed wherein a polymer gel is formed, adding a trialkyl aluminum compound to the polymer gel, whereby the gel dissipates, adding a sufficient amount of a proton source to provide at least 1 mole of protons per mole of lithium ions and at least 2 moles of protons per mole of aluminum wherein the proton source is an organic acid with a pKa of 11 or less or a mixture of the organic acid and an alkanol, provided that sufficient organic acid is added to provide at least 0.

Abstract: A method of manufacturing a on-chip temperature controller by co-implanting P-type and N-type ions into poly load resistors. The N and P type implant dose can be selected to create the desired cut-off temperature. First, a polysilicon layer 30 is formed on a first insulation layer 20. The polysilicon layer 30 is patterning to form a first poly-load resistor 30A and a second poly-load resistor 30B. The first and the second poly-load resistors are connected to a temperature sensor circuit 12. Both p-type and n-type impurity ions are implanted into the polysilicon layer 30. An insulating dielectric layer 40 is formed over the polysilicon layer 30 and the first insulating layer 20. The polysilicon layer is annealed. The contact openings 44 are formed through the ILD dielectric layer 40 exposing portions of the polysilicon layer 30. Contacts 50 to the polysilicon layer 30 thereby forming a first and second poly-load resistors which are used a temperature on-chip sensors.

Abstract: Techniques are disclosed for converting available electrical power to desirable electrical power. One embodiment of the techniques calls for a boost circuit to convert low power Win at a terminal TVin to high power Wout at a terminal TVout. The boost circuit includes a voltage generation circuit, a capacitor Cstore, a timing-control generator, and a boost regulator. The voltage generation circuit converts voltage Vin at terminal TVin to voltage Vstore at a terminal TVstore wherein, in one embodiment, Vstore is less than Vin. Further, the current Icharge provided by the voltage generation circuit at terminal TVstore is less than the current Iin at terminal TVin. In one embodiment, capacitor Cstore, being charged by current Icharge, stores necessary charge to provide appropriate currents and voltages to the boost regulator. The timing-control generator uses voltages Vin and Vstore to provide a timing-control signal Tcontrol, which controls the timing operation of the boost regulator.
Abstract: This invention relates to a method and a device for the processing of silver halide photographic materials. The method of the invention includes accurately measuring the concentration of a developing agent in a photographic developing solution to monitor the activity of the bath and/or the need to replenish it. This measurement is carried out using spectrophotometric means.
Abstract: A screw pump, includes a pump case having a fluid inlet, a pumping chamber, and a fluid discharge with at least two intermeshed parallel screw members rotatably mounted therein and in fluid communication with the fluid inlet and the fluid discharge. One synchronous electric drive motor mounted to each screw member provides the driving power to the screws. Electronic controls are provided for sensing the rotary positions of the motors for synchronizing rotation of the screw members. The pump is also capable of pumping multi-phase fluids.
Abstract: The invention provides a method of producing &agr;-tocopherol and &agr;-tocopheryl esters. The method comprises using a biological system to produce farnesol or geranylgeraniol. Then, the farnesol or geranylgernaiol is chemically converted into &agr;-tocopherol or an &agr;-tocopheryl ester.

Abstract: A first resonance is generated by the inductance of a first coil connected between a first antenna conductor in a window glass sheet and a receiver and the impedance of the antenna conductor, and a second resonance is generated by the inductance of a second coil connected between a second antenna conductor 3b and an automobile body as the earth. The antenna conductor and the antenna conductor are in a capacitive coupling relation, whereby signals in different broadcast band: a low frequency band and a high frequency band, are well received.
Abstract: A method of engraving a gravure cylinder having a circumference C for coating a liquid composition on a substrate. The liquid composition contains a concentration of particles having a predetermined particle diameter. The method includes calculating the engraving channel depth Do based on a first ratio of the particle diameter to channel depth (DB/Do). Then, engraving the gravure cylinder according to &thgr;, &agr;, WC, Ww, and Wo.

Abstract: An apparatus and method are provided for integrating an intelligent manufacturing system with an expert sheet metal planning and bending system. The intelligent manufacturing system manages and distributes part design and manufacturing information throughout the locations of a production facility. The expert planning system includes a plurality of expert modules for proposing a bending plan, including bend sequence and tooling selections, and robot motion planning and repositioning. Through the various features and aspects of the present invention, an operator can selectively modify and adapt these integrated systems for particular bend applications, including robot-based and human assisted bending operations.
Abstract: A fixture, such as a light fixture includes a housing and a mounting base having a connector. The housing includes a first mating connector positioned on an end of the housing to permit attachment of the housing to the mounting base with the end of the housing adjacent to the mounting base, a second mating connector positioned on a side of the housing to permit attachment of the housing to the mounting base with the side of the housing adjacent to the mounting base, and a third mating connector positioned on a top of the housing to permit attachment of the housing to the mounting base with the top of the housing adjacent to the mounting base. A lens panel extends from the bottom of the fixture.
Abstract: A system controller controls, when successive operations for imaging are to be executed, the second operation for imaging at the timing when the image data obtained in the first operation for imaging is read out from the imaging element, and controls, after start of the second operation for imaging, the light-shuttering operation at the timing earlier than the timing when the image data obtained in the second operation for imaging is read out from the imaging element, and shutters the light to the imaging element with the optical mechanism, so that the control of the second operation for imaging is immediately executed at the timing when the image data obtained in the first operation for imaging is read out without any restriction by the timing when image data is read out from the imaging element.
Abstract: This invention relates to metallized, particularly aluminized, fabrics which are coated with specific polyurethane finishes. Such specific polyurethanes must be cross-linked and present in latex form. Upon impregnation within metal-coated fabrics, these particular polyurethanes provide vastly improved washfastness properties to the fabrics and thus ensure the retention of substantially all the metal coating within and on the target fabric.
