Abstract: A sheet storage device includes a sheet positioning member that is movable in a first direction, and positions a sheet by abutting on a side end portion of the sheet at a side in the first direction. The sheet positioning member includes a moving body, an abutting portion, a first and a second biasing member, and a bias removing portion. The moving body is configured to move in the first direction. The abutting portion is supported by the moving body to be movable in the first direction and configured to abut on the side end portion when the sheet positioning member positions the sheet. The first biasing member biases the abutting portion toward the side end portion. The second biasing member biases the abutting portion against a biasing force of the first biasing member. The bias removing portion removes a bias applied by the second biasing member.

Abstract: This invention proposes the aerodynamic designing method for the central section of small size gas turbine engine type and it includes the following 8 steps: 1st step: checking to confirm if compressor outlet air meets demand specified by the central section; 2nd step: estimating the inner casing diameter based on practical experience; 3rd step: estimating the outer casing diameter; 4th step: estimating the combustor dome height and combustor length; 4th step: estimating the combustor dome height and combustor length; 5th step: estimating the combustor inner and outer liner diameters; 6th step: estimating the exit inner and exit outer diameters of the pre-diffuser; 7th step: estimating the dump gap; 8th step: verifying rotordynamic properties to determine if the shaft diameter assumption starting in the 2nd step is good enough.

Abstract: Aspects of the disclosed technology relate to an active array system that can form and steer a directed beam across its aperture. The disclosed array system utilizes a novel configuration that significantly reduces a number of transmit and receive elements. In some aspects, the disclosed array system can be configured with a modular design, for example, to permit the extension of the transmit/receive array, e.g., to increase/decrease aperture size. In other aspects, the disclosed array system may be configured to dispose the elements of either the first or second group of radiators in a modular fashion.

Abstract: A sheet positioning member is provided on a sheet placing surface in such a way as to be movable in a predetermined first direction. The sheet positioning member includes a moving body, an abutting portion, an operation member, and a cam portion. The moving body moves in the first direction on the sheet placing surface. The abutting portion has an abutting surface that abuts on the side end portion when the sheet positioning member positions the sheet. The operation member is supported by the moving body so as to be pivotable around a support shaft that extends in the first direction, on a side of a back surface of the abutting portion. The cam portion displaces the abutting portion toward the side end portion by being pressed by the operation member in response to a pivoting operation of the operation member.

Abstract: An image forming apparatus includes a casing in which multiple units are disposed. The casing has a front wall having a first opening and a stepped wall having a second opening. In the casing, an exposure unit is disposed in front of an image forming unit, above the first opening, and above a sheet loading section, and a fixing unit is disposed above the image forming unit. The exposure unit is disposed with a first gap between the exposure unit and the image forming unit, and the fixing unit is disposed with a second gap between the exposure unit and the image forming unit. The first gap and the second gap constitute a ventilation channel for distributing outside air flowing into the casing through the first opening to the second opening.

Abstract: The invention provides a solution to amplify the airflow for testing purpose; this solution could be conventionally set up and configured with simple components or popular industrial systems. It is particularly interesting for small facilities/companies with limited resources or demanding only a low investment. This system is consisted of a high pressure air driving duct, an air mixing duct, a pressure reduction valve and a safety valve, ducts' size can be configured or changed to adapt the testing configuration. All components and systems are connected and attached to each other by stainless steel flanges and seals to avoid leakage and corrosion.

Abstract: Systems and methods for creating a narrow vertical pathway of detection that permits the enforcement of a fixed “exclusion zone” that is narrow and does not widen with range. An advantage to this approach is that the zone or corridor does not widen with range, permitting a fixed exclusion zone that will ignore items that will pass above or below the wing. An exemplary system located on a vehicle includes at least two vertically separated antennas that receive radar reflection signals, a processor, and an output device. The processor receives the radar reflection signals received by the antennas, determines vertical position of any obstacles identified in the radar reflection signals and determines if the obstacles are within a predefined alert zone. The output device outputs an alert if any obstacle is within the alert zone. The predefined alert zone is related to a protruding portion of the vehicle.

Abstract: A method of generating an image of a volume ahead of an aerial vehicle is provided. The method comprises determining a position of the aerial vehicle and generating a terrain image corresponding to ground features correlated to the position of the aerial vehicle. Obstacle data pertaining to a set of obstacles ahead of the aerial vehicle is determined with a forward looking sensor. An obstacle overlay image is generated and overlain onto the terrain image to generate a composite image.
