  • Patent number: 8662648
    Abstract: A liquid consumption apparatus includes a detection portion in which a light emitting portion and a light receiving portion are arranged, a liquid container that houses a liquid and in which a prism having a cavity is disposed, a carriage with respect to which the liquid container is attachable and detachable, and in which an opening is provided in a position that opposes the prism, and a light shielding portion disposed in the opening in the carriage. When a driving portion moves the carriage in a direction in which the light emitting portion and the light receiving portion are arranged, noise light produced by the prism bottom surface or cavity portion is suppressed, as a result of the light shielding portion blocking part of irradiated light.

  • Patent number: 8350802
    Abstract: Disclosed is a method of driving an electrophoretic device that includes an electrophoretic element having a first electrode, a second electrode, and an electrophoretic layer disposed between the first and second electrodes, and further includes a capacitor connected to the first electrode at one terminal. The method includes (a) applying a reference potential or a first potential higher than the reference potential to the first electrode of the electrophoretic element and the terminal of the capacitor and applying the reference potential to the second electrode of the electrophoretic element, and (b) applying a signal fluctuating between a second potential and a third potential to the second electrode subsequently to the step (a), the second potential being equal to or higher than the reference potential, the third potential being higher than the second potential and being equal to or lower than the first potential.

  • Publication number: 20120293590
    Abstract: A liquid chamber for a liquid ejecting apparatus includes a prism disposed on a bottom portion of the liquid chamber. The prism includes a first reflection surface having a first reflection region by which light incident on the prism from a light emitting element is reflected when liquid does not make contact with the first reflecting region. The prism includes a relief that includes a first relief surface opposed to the first reflection region. The thickness of the prism between the first reflection region and the first relief surface is substantially constant. The constant thickness of the prism between the first reflection region and the first relief surface suppresses deflection of the first reflection region, thereby improving sensitivity for the detection of liquid in the liquid chamber.

  • Publication number: 20050034830
    Abstract: [Problems]To provide a wet paper friction member with both excellent friction property and high frictional coefficient. [Solution Means]A wet paper friction member is produced by impregnating a paper body with thermosetting resin, curing it by heating and then forming it by pressure. The paper body comprises cellulose pulp and a filler and further comprises aramid pulp the drainability of which is adjusted to 200-400 ml and aramid pulp the drainability of which is adjusted to 450-700 ml, respectively at 10-30 wt % of a total weight of the paper body, and said whole aramid pulp the drainability of which is adjusted comprises 30-50 wt % of a total weight of the paper body. Its surface roughness before and after pressure forming is adjusted so that the load length ratio Rmr (30%)?55% as the load length ratio is defined by Rmr(C) (C: cutting level %). Thus, high frictional coefficient, heat resistance and mechanical strength are realized simultaneously.
