摘要:
A microfluidic printing apparatus includes at least one ink reservoir; a structure defining a plurality of chambers arranged so that the chambers form an array with each chamber being arranged to form an ink pixel; a plurality of microchannels connecting the reservoir to a chamber; and a plurality of microfluidic pumps each being associated with a single microchannel for supplying ink from an ink reservoir through a microchannel for delivery to a particular chamber. The printing apparatus provides an electrical signal representing the orientation of the printing apparatus; and control circuit responsive to the electrical signal and for controlling the microfluidic pumps for causing an array of pixels to be printed when the microfluidic pumps supply ink through the microchannels to the chambers so that the correct amount of ink is delivered into each chamber.

A resistive thermal printer has a platen drive mechanism which includes (1) a thermal printhead having an array of selectively-activatable thermal elements and (2) a rotatably-driven platen roller opposed to the printhead and forming a nip with the printhead through which a receiver medium is driven by the platen roller while the thermal elements are selectively activated. The platen roller has an outer layer of perfluorinated polymer. The platen roller includes a compliant layer below the outer layer of perfluorinated polymer.

A process is disclosed of preparing a high bromide tabular grain emulsion comprising (1) in a grain nucleation step creating in a dispersing medium tabular grain nuclei containing parallel twin planes and (2) in a grain growth step subsequently growing the grain nuclei into tabular grains by running into the dispersing medium high bromide silver halide grains having a maximum equivalent circular diameter of less than 40 nm, wherein (a) the high bromide grains are formed prior to the grain nucleation step and then held in the presence of a grain growth restrainer adsorbed to the grain surfaces to inhibit grain ripening and (b) during the growth step the restrainer is desorbed from the high bromide grains and silver and halide ions forming the high bromide grains are released by ripening into the dispersing medium in the growth step.

A chemically and spectrally sensitized ultrathin tabular grain emulsion is disclosed including tabular grains (a) having {111} major faces, (b) containing greater than 70 mole percent bromide and at least 0.25 mole percent iodide, based on silver, (c) accounting for greater than 90 percent of total grain projected area, (d) exhibiting an average equivalent circular diameter of at least 0.7 .mu.m, and (e) exhibiting an average thickness of less than 0.07 .mu.m.It has been observed that faster rates of development, relatively thinner tabular grains under comparable conditions of preparation, increased contrast and improvements in speed-granularity relationships can be realized when (1) the tabular grains contain less than 10 mole percent iodide and (2) the surface chemical sensitization sites include epitaxially deposited silver halide protrusions of a face centered cubic crystal lattice structure of the rock salt type forming epitaxial junctions with the tabular grains, the protrusions (a) being restricted to those portions of the tabular grains located nearest peripheral edges of and accounting for less than 50 percent of the {111} major faces of the tabular grains, (b) containing a silver chloride concentration at least 10 mole percent higher than that of the tabular grains, and (c) including a higher iodide concentration than those portions of the tabular grains extending between the {111} major faces and forming epitaxial junctions with the protrusions.A photographic element is disclosed in which an ultrathin tabular grain emulsion as described above is coated over an emulsion layer intended to record visible light.

The present invention provides a process for regenerating a deactivated heteropolymolybdophosphoric acid catalyst, comprising the steps of grinding the deactivated catalyst into particles having a particle size of 40 mesh or less, mixing the particles with a mixture comprising aqua ammonia, which is an aqueous solution containing ammonium ions and organic auxiliaries, kneading the mixture of particles and aqua ammonia in a kneader to obtain a paste, drying the paste, molding the paste into cylindrical particles with a through hole in its longitudinal axis, and heating the paste in atmosphere at 350˜450° C. for 1˜10 hours to produce the generated catalyst.
摘要:
A method for collecting images by an image-processing provider from a plurality of users using an automated station. The method includes receiving a wireless signal comprising image information by a wireless receiver port in the automated station, accepting user-identifier information into a computer in the automated station, wherein the user-identifier information is associated with a user, and accepting order information into the computer, wherein the order information specifies a service to be provided relative to the image information. The method further includes storing into a local storage in the automated station and coupled to the computer, a digital representation of the image information and associated user identifier information and order information for each of a plurality of different users into a data structure, and sending the data structure to the image-processing provider via a communication network.
摘要:
System and method for collecting customers' images into a kiosk, and transferring images to an image-processing provider for processing. The kiosk includes a computer, a data storage device, an upload port, and an interface for capturing digital images. One method includes accepting image information from a customer into the interface of the kiosk, accepting user-identifier and order information into the kiosk computer, storing a digital representation of the image and associated user-identifier and order information for each customer into a data structure, and sending the data structure to the image-processing provider via the upload port connected to a communication medium such as the internet. Some embodiments also include accepting credit-card payment information, displaying to the customer at least one image from the image information and/or a plurality of thumbnail images from the image information, and/or printing a receipt and/or a printout of thumbnail images from the image information. Optionally, the user specifies a modification to be made to the image information and/or specifies a plurality of delivery addresses. Optionally, the kiosk includes optical scanning of film or prints to generate digital images, transferring image data directly from a digital camera, transferring image data directly from a storage medium, and/or transferring image data into a kiosk data port. Some embodiments include accepting a container of undeveloped film into the kiosk, processing the undeveloped film in the kiosk, and optically scanning the developed film to generate digital representations of the developed film.
摘要:
An automated manufacturing system comprises a computer processing system and a plurality of consolidation systems. The computer processing system receives information on product subbatches and product packages and consolidation status information to produce consolidation assignment information, each product package comprising one or more product subbatches. The consolidation systems receive the product subbatches in accordance to the consolidation assignment information and consolidate the product subbatches into product packages, wherein the status of the consolidation systems are tracked and the consolidation status information is sent to the computer processing system.
