摘要： A method for timing a deflection correcting electrical pulse relative to operational pulses of an asymmetric thermal droplet deflector of a continuous ink jet printer having nozzles, including the steps of generating a line image data with image data values corresponding to the nozzles, the image data values being indicative of desired pixel graytone levels for the nozzles, comparing the image data values to reference values, generating a serial bit stream in the form of a serially arranged bits based on the comparison of the image data values to the reference values, and producing an actuation value that times the deflection correcting electrical pulse in the serial bit stream when the image data value is equal to the reference value being compared to. The deflection correcting electrical pulse is timed to the actuation value in the serial bit stream.

摘要： A method for placing an edge piece on a battery plate includes bending a thin strip of bendable plastic material into an open top, U-shaped channel. The channel is then cut into an edge piece having a length which is substantially equal to the edge of the battery plate which is to be covered. The edge piece is supported with this open top oriented towards a battery plate that is transported toward it in a manner such that the battery plate edge will be inserted into it. Once the edge of the battery plate has been inserted into the edge piece the edge piece is released so that the battery plate can be carried out of the apparatus. An apparatus for accomplishing this includes a feed mechanism which transports the strip of bendable plastic material. A bending mechanism forms this strip into the open top, U-shaped channel. The channel is then fully inserted into an assembly station where a first sensor stops the feed mechanism and a cutter cuts the channel into the proper-sized edge piece. An in-feed conveyor transports a battery plate toward the edge piece, and a support mechanism supports the edge piece while the edge of the battery plate is inserted into it. The support mechanism then releases the edge piece so that it can travel out of the insertion station with the battery plate. A second sensor restarts the feed mechanism once the battery plate is completely out of the assembly station.

摘要： A cartridge follower for pushing against cartridges in a tubular magazine of a shotgun. A front face of the follower has at least one forwardly protruding member offset from the center of the front face to be tactilely distinguished from a cartridge in the magazine, but which cannot contact a central primer of a backwards cartridge. A method for determining whether a shotgun is empty includes providing such a follower in the magazine, inserting a finger into the outfeed end of a magazine, and attempting to feel the protruding member.

摘要： A portage apparatus for a lightweight water craft having a central frame, comprising a receiver member attached to the central frame. A proximal end of an engaging member couples in a selected orientation to the receiver and is fastened thereto. A wheel permits the water craft to be manually lifted and rolled, wheelbarrow fashion. The receiver and engaging member preferably are tubular. A method for portaging a water craft of a type having a central frame comprises attaching a receiver member to the central frame of the water craft. A wheel assembly is engaged with the receiver member and coupled thereto. The water craft may then be manually lifted and rolled in wheelbarrow fashion over land. The wheel assembly is then decoupled from the receiver member, and the water craft and receiver member is slid into the-water until the water craft floats on a water surface.

摘要： A color mapping scheme is provided which enables a K-only black point while minimizing interpolator image artifacts. Specifically, a system and method of reducing image artifacts for a color imaging device include implementing a color map so that no C, M or Y color value that is used in defining the black point is produced, except at the black point. The system and method further include implementing a halftone ramp so that: (i) a halftone pattern is selected to provide no rendering for any C, M or Y color value that is used in defining the black point, and (ii) a halftone pattern is selected to provide a full rendering for any K color value that is used in defining the black point. The color map is also implemented so that no C, M or Y color value that is used in defining the black point is obtained as a result of interpolation, except for at the black point.

摘要翻译： 通过三步骤或四步骤程序产生具有一致的低比接触电阻（<1×10-6 OMEGA-cm2）到n型GaAs（10）的可靠欧姆接触。 在GaAs衬底中用于与其接触以形成掺杂区域之后采用的步骤包括：（a）在硫酸盐的位置处将硫或含硫化合物（26）与GaAs表面（10'）吸附或反应， 接触金属（28）将被沉积; （b）在GaAs表面的处理部分上形成金属接触层（28）; （c）任选地在所述金属接触件上形成保护层（30）; 和（d）加热组件（金属和基底）以形成最终的欧姆接触。 表面处理提供了欧姆接触的较低的比接触电阻。 由于在金和铝互连之间形成的金属间化合物（“紫色瘟疫”）被避免，在欧姆接触中消除金进一步改善了接触。 此外，金属中不存在金，提高了欧姆接触的可靠性，并且可以通过蚀刻或剥离工艺对所得金属进行图案化。

摘要： This invention discloses a method for enhancing memory in a patient comprising administering a compound of formula ##STR1## wherein R.sub.1 and R.sub.2 are independently selected from the group consisting of hydrogen and a lower alkyl group; m is an integer between about 0 and 4; and n is an integer between about 5 and 14. The methods generally comprise administering an effective amount of the compound. The invention also discloses the enhancement of memory by the use of non-steroidal sulfatase inhibitors of the above formula in conjunction with the naturally occurring neurosteroids dehydroepiandrosterone sulfate (DHEAS) and/or pregnenolone sulfate (PS). The patients benefitting from the methods of the present invention will generally have an illness that causes memory loss, or will be individuals who otherwise want to improve memory.

摘要： A two-phase acidic aqueous composition for use as a neutralization layer is generally comprised of a water soluble aqueous phase and a water insoluble particle phase. The particle phase generally comprises a copolymer having recurring units of an organic acid monomer and an organic ester monomer. The aqueous phase comprises a water soluble polymer having recurring units of at least an organic acid monomer. The organic acid monomers selected for the aqueous phase polymer are capable of interacting with the particle phase polymers such that the particle phase polymers are brought into stabilizing, intimate association with the aqueous phase.
