Patent number: 6692108Abstract: There is disclosed an ink jet printhead which comprises a plurality of nozzles and one or more heater elements corresponding to each nozzle. Each heater element is configured to heat a bubble forming liquid in the printhead to a temperature above its boiling point to form a gas bubble therein. The generation of the bubble causes the ejection of a drop of an ejectable liquid (such as ink) through the respective corresponding nozzle, to effect printing. Each heater element is configured such that an actuation energy of less than 500 nanojoules (nJ) is required to be applied to that element to heat it sufficiently to form such a bubble in the bubble forming liquid (which liquid can also be the ink). This configuration thus provides for a high efficiency printhead.Type: GrantFiled: November 23, 2002Date of Patent: February 17, 2004Assignee: Silverbrook Research Pty Ltd.Inventors: Kia Silverbrook, Angus John North, John Gregory Mcavoy

Patent number: 6647748Abstract: A device for continuously twisting an optical fiber, which can add a sufficient twist to an optical fiber, is provided. Reciprocating rollers reciprocate so that the moving direction would be opposite each other along a center axis of rotation. The optical fiber passes through a gap between the reciprocating rollers and runs in contact with the outer circumferential surface of respective reciprocating rollers in order. Reciprocation of the reciprocating rollers adds a twist to the optical fiber. When &phgr; is a contacting angle between the optical fiber and the reciprocating rollers, F is maximum static friction of the optical fiber against the outer circumferential surface of the reciprocating rollers, and T is tension of the optical fiber, the coefficient of friction &mgr; between the optical fiber and the outer circumferential surface of the reciprocating rollers is lead from an operational formula of &mgr;=(1/&phgr;)·ln(F/T).Type: GrantFiled: November 28, 2001Date of Patent: November 18, 2003Assignee: The Furukawa Electric Co., Ltd.Inventor: Nobuaki Orita

Patent number: 5703991Abstract: An optical part module has an optical amplification fiber in a small space without damage or losing its optical characteristics. An optical amplification fiber connects optical parts in the case. The optical amplification fiber has a predetermined length which creates a large play in length. A part of the optical amplification fiber creating the play in length is wound on the bobbin. The winding operation is performed while turning the bobbin upside down for each single turn of the winding so that twist generated in the optical fiber due to winding is canceled.Type: GrantFiled: February 14, 1996Date of Patent: December 30, 1997Assignee: Fujitsu LimitedInventor: Shigeichi Izumi

Patent number: 4597255Abstract: A device for controlling the twist associated with optical fiber being wo on a bobbin is disclosed. Signal transmission analysis in fibers wound on bobbins require techniques not normally encountered when considering long straight fibers. Signal loss on a fiber cable payout assembly is mainly due to small bends in the fiber at crossover positions and in the transmission regions where the winding travel changes directions. The signal attenuation in a length of optical fiber is also known to be a function of the amount of twist in the fiber both in the wound and payed out states. This invention allows the amount of twist of the optical fiber to be precisely controlled from zero to full (360 degrees twist per turn of the bobbin) twist to provide optimum signal transmission for both the wound and payed out states.Type: GrantFiled: December 24, 1984Date of Patent: July 1, 1986Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Joe S.
