  • Patent number: 11926103
    Abstract: An approach to precision additive fabrication uses jetting of cationic compositions in conjunction with a non-contact (e.g., optical) feedback approach. By not requiring contact to control the surface geometry of the object being manufactured, the approach is tolerant of the relative slow curing of the cationic composition, while maintaining the benefit of control of the deposition processes according to feedback during the fabrication processes. This approach provides a way to manufacture precision objects and benefit from material properties of the fabricated objects, for example, with isotropic properties, which may be at least partially a result of the slow curing, and flexible structures, which may not be attainable using conventional jetted acrylates.

  • Patent number: 11912013
    Abstract: Ink-based digital printing systems useful for ink printing include a rotatable charge-retentive reimageable surface layer configured to receive a layer of fountain solution. The fountain solution is carried to the charge retentive surface by a fog or mist including fountain solution aerosol particles, dispersed gas particles, and charge directors that impart charge to the fountain solution aerosol particles. The charge-retentive reimageable surface may be charged to a uniform potential, and selectively discharged using an ROS according to image data to form an electrostatic latent image. The charged fountain solution adheres to portions of the charge-retentive reimageable surface according to the electrostatic latent image to form a fountain solution image thereon. The fountain solution image can be partially transferred to an imaging blanket, where the fountain solution image is inked. The resulting ink image may be transferred to a print substrate.

    Abstract: A three-dimensional (3D) metal object manufacturing apparatus is equipped with a wire detector to determine a position of a top surface of melted metal contained in a receptacle of a heated vessel in the apparatus from time to time. The solid metal wire being fed into the heated vessel is retracted and the length of the retracted wire is determined using a signal generated by the wire detector. The determined length of the wire is used to identify the position of the top level of the melted metal in the receptacle so the receptacle can be replenished if the level has fallen below a predetermined capacity for the receptacle.

  • Patent number: 8227255
    Abstract: A biosensor capable of analyzing an object, such as antigen, antibody, DNA or RNA, through detection of magnetic field to thereby allow washout of unbound label molecules to be unnecessary, which biosensor is compact and available at low price, excelling in detection precision. Coils are arranged at an upper part and a lower part of a magnetic sensor using a hall element as a magnetic field detection element. An object and magnetic particles having an antibody capable of specific bonding with the object bound to the surface thereof are introduced in the magnetic sensor having a molecular receptor capable of specific bonding with the object attached to the surface thereof. Therefore, a change in magnetic field by magnetic particles bonded through the molecular receptor to the surface of the magnetic sensor is detected by means of the hall element.

  • Publication number: 20110159201
    Abstract: A method of forming a pattern includes: providing a heating substrate that selectively controls positions where heat is generated by controlling locations where electric current flows; forming a pattern forming material on a surface of the heating substrate; aligning a patterning substrate, on which a pattern may be formed, to face a surface of the heating substrate; and selectively applying electric current to the heating substrate to transfer some of the pattern forming material onto the patterning substrate. According to the method of forming the pattern and a method of fabricating an OLED, the pattern is transferred by heating the pattern forming material formed on the heating substrate, and thus, the pattern may be formed with high accuracy without using a mask, and the pattern forming material remaining on the heating substrate may be re-used.

    Abstract: Printing one or more layers using toner and/or laminates to form one or more multi-channeled layers, with a particular pattern, including forming a desired image, for example, electrographically, on a receiver member. The multi layered channel printing apparatus and related method and print incorporates one or more static layers, and one or more moveable layers that allow a fluid to move through the micro channels via an opening or through a direct fill. It also incorporates particles in the channels to act as a packing material for separation of components of samples. The packing material can either be applied directly or using the electrographic printing process. An optional capping layer or substrate may then be applied.

  • Patent number: 7910175
    Abstract: A coating of an encapsulated electrophoretic medium is formed on a substrate (106) by dispersing in a fluid (104) a plurality of electrophoretic capsules (102), contacting at least a portion of a substrate (106) with the fluid (104); and applying a potential difference between at least a part of the portion of the substrate (106) contacting the fluid (104) and a counter-electrode (110) in electrical contact with the fluid (104), thereby causing capsules (102) to be deposited upon at least part of the portion of the substrate (106) contacting the fluid (102). Patterned coatings of capsules containing different colors may be deposited in registration with electrodes using multiple capsule deposition steps. Alternatively, patterned coatings of capsules may be formed by applying a fluid form of an electrophoretic medium to a substrate, and applying a temporally varying voltage between an electrode and the substrate. The process may be repeated to allow for deposition of full color displays.
