  • Patent number: 11440048
    Abstract: A method of creating a bulk product that includes a surface layer of specialized content is based upon the use of an excipient with a different surface tension such that self-differentiating of the excipient from the bulk during drying/curing transports the specialized material to the surface of the bulk product. When the excipient has a lower surface tension than the bulk material, the difference in surface tension causes the low surface tension material to rise to the top surface, bringing the specialized material along. Alternatively, if the excipient has a higher surface tension than the bulk material, it will transport the specialized material to the bottom surface of the product.

    Abstract: A reading apparatus includes a cover configured to pivot to an open position and a closed position, a lock mechanism configured to restrict the cover in the closed position from pivoting to the open position, and a reading unit provided in the cover or in a member facing the cover in the closed position, and configured to read a medium when the cover is in the closed position. The cover includes a protruding portion. A latch face configured to come into contact with a face of the protruding portion facing toward one direction along a first axis when the cover is in a closed position, the first axis being orthogonal to a pivoting shaft of the cover. The latch face is configured to move in the other direction along the first axis when the latch moves from a lock release position to a lock position.
