Abstract: The present invention is about a pressure-adjustment means for ink jet cartridges. An element, which is an elastic air-bag, is employed inside the ink jet cartridge. The air inside the elastic air-bag is in ventilation with the air external to the ink jet cartridge. When the pressure difference between the air pressure inside the air-bag and the back pressure of the ink-cartridge undergoes changes, this elastic air-bag may then automatically adjust its own volume by expansion or contraction by virtue of its elastic structure, and in turn modify the ink volume inside the cartridge, so that the ink contained inside the ink jet cartridge is prevented from leaking while permitting the printhead to be able to continue releasing ink droplets outwards in spurts.

Title: Method for forming fiber grating and fiber grating formed by the same
Inventor: KOKURA KUNIO
IPC: G02B6/10
Filed: 1999-06-23
Granted: 2008-07-29
Abstract: A fiber grating formed in an optical component for optical communication and optical signal processing and a method for forming the same are disclosed. The coating (2) of a coated optical fiber (3) is partly removed, and then a resin film (7) having a thickness thin enough to exhibit an ultraviolet transmittance which does not obstruct the formation of a grating is formed over the surface of the exposed portion of the optical fiber (1). Thereafter ultraviolet radiation (ultraviolet coherent light) is applied from the surface side of the resin film (7) through a phase mask (9) so as to form a grating in which the refractive index of the core (4) of the exposed optical fiber (1) periodically varies in the optical axis. The resin film (7) is made of, for example, an organic material having a heat-resistance which is so high that it does not melt by the heat produced by ultraviolet radiation application, such as a polyimide resin or polyamide/imide resin. The thickness of the resin film (7) is 10 .mu.m or less, so that ultraviolet light can sufficiently pass through the film (7) and hence the focusability of coherent light is not degraded.

Title: Fast gain control for optical amplifiers
Inventor: HUNZIKER GUIDO HERMANN
IPC: H04B10/29
Filed: 2000-08-14
Granted: 2004-10-05
Abstract: In an optically amplified wavelength division multiplexed (WDM) system having a WDM signal comprising a plurality of optical channels, the per-channel gain of the optical channels is kept relatively constant despite changes in input power at the optical amplifier, such as when individual optical channels of the WDM signal are added and dropped. More specifically, gain of an optical amplifier is controlled by controlling the amount of pump power supplied to the optical amplifier as a function of changes in input power which are measured in a feed-forward monitoring path. The amount of pump power for effecting gain control is adjusted according to a scaled relationship to the measured input power of the optical amplifier. By controlling the pump power directly in response to changes in input power, gain of the optical amplifier can be controlled within a sub-microsecond time scale from the time that a change in input power is detected.  Moreover, by maintaining relatively constant per-channel gain in an amplified WDM signal despite changes in input power at the optical amplifier, power excursions are substantially reduced in surviving optical channels of the WDM signal, i.e., those at the output of the optical amplifier.

Inventor: WELLMAR PAR
IPC: B65G53/66
Filed: 1998-12-22
Granted: 2007-02-13
Abstract: The present invention provides a method and plant for the pneumatic transportation of solid particles in the form of a diluted phase through a conduit (1), with which the transport sir in said conduit is given a velocity which is at most equal to the air velocity chosen for a maximum particle load level. The free flow from the pressurised air source (3) is regulated on the basis of measured air velocity or on the basis of a state corresponding thereto, such as air pressure in the conduit, and an established relationship between the free flow and the said measured velocity of the air or a state (pressure) corresponding theret o, essentially independently of the particle load. There is thus maintained in the conduit a preferably constant transport air velocity with all different occurring levels of particle load.

Title: Aircraft landing gear with integrated brake actuation system
Inventor: HAUGEN DEROLLE E
IPC: F16D65/18
Filed: 2000-09-12
Granted: 2008-11-18
Abstract: An aircraft brake assembly, wherein the actuator portion of the brake assembly is no longer provided as part of the brake assembly but instead as part of the aircraft landing gear. Accordingly, the actuator portion or individual actuators assemblies are designated as Line Replacement Units (LRUs), which are replaceable independently of other brake components, e.g., the torque tube and heat sink, which then comprise the brake assembly designated as a separate LRU.  This new arrangement is particularly suited to electro-mechanically actuated brakes, where actuator maintenance intervals will typically be more closely related to landing gear maintenance intervals than to brake maintenance (i.e., hydraulic actuator and/or heat sink maintenance). The invention also provides for more effective and desirable mounting of one or more electro-mechanical actuators wherein reactionary loads are transferred in compression as opposed to in tension through mounting bolts or other removable fasteners.

Title: System based control of optical amplifier transmission functions
Inventor: BODE DIRK
IPC: H04B10/29
Filed: 2000-12-11
Granted: 2005-02-08
Abstract: Each of a series of optical amplifiers is arranged such that, in response to detecting particular stimuli occurring at an input or receipt of an adjustment start message from an upstream amplifier, adjusts certain amplifier parameters using small steps and completes the adjustment using large steps if it does not receive the adjustment start message within a predetermined period of time of starting the adjustment in response to detecting the stimuli. If the optical amplifier receives the adjustment start message, then it continues to perform the adjustment and completes the adjustment using large steps when it receives an adjustment done message from the upstream optical amplifier. At that point, the optical amplifier sends an adjustment done message to the next downstream amplifier if it is not the tail-end amplifier.
