A process cartridge detachably mountable to an electrophotographic image forming apparatus main body, including: an electrophotographic photosensitive drum; a cleaning member for removing developer adhering to the photosensitive drum; a removed developer containing portion for containing the developer removed by the cleaning member; a filter member mounted to the removed developer containing portion for allowing ventilation between the interior and exterior of the removed developer containing portion; a recess provided on the removed developer containing portion and covered with the filter member; and a communicating portion provided on the removed developer containing portion for communicating between the interior of the removed developer containing portion and the recess to ventilate therebetween.

Techniques for filtering light include, along a central optical axis, an entrance window; a first polarizer, a narrowband polarization-changing material, a second polarizer, and an exit window. The optical paths through the filter are substantively unscattered and pass through unstressed components between the polarizers. The polarization-changing material changes polarization for a narrow wavelength band on the order of about 0.01×10−9 meters and does not condense on optical windows and polarizers during the operational lifetime. An aspect ratio, defined by a distance from the entrance window to the exit window divided by an optical aperture for the entrance window, is less than 4 / 1. This filter thus transmits light substantively unattenuated in the narrow wavelength band up to a maximum acceptance angle greater than 5 degrees. Combined with optics and imaging detectors, it is suitable for wide area surveillance, including daylight surveillance for combustion like forest fire and missile plume.

An implantable pump and methods for detecting leaks in an implantable pump are provided. In one embodiment, the implantable drug pump includes a housing having at least one inlet port and an outlet port formed therein. The outlet port is adapted to communicate with a catheter for delivering fluid to a patient's body, and the inlet port(s) are effective to deliver fluid into the housing. The housing further includes at least one reservoir disposed therein and effective to contain a fluid. In use, the pump preferably includes a fluid having one or more drugs disposed in at least one of the reservoirs, and a radiolucent fluid disposed in one of the reservoirs. A user programmable control mechanism is coupled to the drug pump and is effective to selectively control movement of the valves between the open and closed positions.

An article conveying robot system capable of effectively containing an article in a container conveyed by a conveyor by using a robot. A container detecting part measures the distribution of shading of an image of each containing cell based on a detection result of the container, detects the containing state of each cell, and stores the detection result of each cell. An information managing part of a controller of an upstream side robot receives information from a container detecting part of a controller of a downstream side robot, and then generates containing cell information. An information managing part checks the cell information to be processed, and then transmits the cell information to a task executing part only when an article is not located in the corresponding cell. Task executing part controls the robot so as to locate an article in the selected cell based on the cell information.

A highly reliable semiconductor device is manufactured by giving stable electric characteristics to a transistor in which an oxide semiconductor film is used. A p-type oxide semiconductor material is contained in an n-type oxide semiconductor film, whereby carriers which are generated in the oxide semiconductor film without intention can be reduced. This is because electrons generated in the n-type oxide semiconductor film without intention are recombined with holes generated in the p-type oxide semiconductor material to disappear. Accordingly, it is possible to reduce carriers which are generated in the oxide semiconductor film without intention.

Apparatuses and methods for contacting radially flowing fluids with a solid particulate (e.g., catalyst) with reduced tendency to form fluid jets that impinge on the solid particulate, leading to solid attrition and plugging, are described. Representative particle retention devices for use in these apparatuses and methods have flow channels passing therethrough, from a first surface to an opposing second surface that is adjacent to a particle retention zone. Widths of the flow channels at this opposing second surface will exceed their smallest flow channel widths.

Compositions of TNF family of cytokines in covalently linked trimeric forms are disclosed. The resulting fusion proteins are secreted as disulfide bond-linked homotrimers, which are more stable in structure and therapeutically more efficacious than their native counterparts.

A device that deploys during a blade portion failure that encompasses the engine casing is provided to prevent damage caused by the failure. A blade containment device such as a flexible interwoven structure or a net encompasses the engine casing and the blade failure path, or is embedded in the engine casing, and deploys in the event of a blade failure, such as the breaking of an engine blade. The net deploys when the blade portion has failed and has started expanding along the blade failure path, and may include a number of links attached to one another. Upon impact with a broken blade portion, thus transferring the kinetic energy of the blade portion to the net, some or all of the links may break off from each other, thus allowing the net to deploy and dissipating the kinetic energy generated by the expanding broken blade. Consequently, the blade remains contained inside the net, and blade containment is improved.

A novel thin film encapsulated OLED panel architecture and a method for making the panels with improved shelf life is disclosed. The OLED panel consists of a plurality of OLED pixels; each OLED pixel is individually hermetically sealed and isolated from its neighboring pixels. The organic stack of the OLED pixel is contained within its own hermetically sealed structure, achieved by making the structure on a barrier coated substrate and using a first barrier material as the grid and a second barrier for encapsulating the entire OLED pixel. The first barrier material provides the edge seal while the second barrier disposed over the pixel provides protection from top down moisture diffusion. By isolating and hermetically sealing individual pixels; any damage such as moisture and oxygen ingress due to defects or particles, delamination, cracking etc. can be effectively contained within the pixel thereby protecting other pixels in the panel.
