Abstract: In the disclosed method of fitting a fixed flush glazed window of a high-speed rail vehicle, a first edge of the window is first placed from the exterior of the vehicle in a groove situated on a horizontal portion of the window frame, after which the window is tilted to move the opposite second edge of the window toward the opposite horizontal portion of the window frame, and finally the opposite second edge is fixed to the opposite horizontal portion of the window frame from inside the vehicle. Thus there is no mechanical fixing to the horizontal portion of the window where the groove is located, so that it is no longer necessary to demount all of the interior fittings when changing a window, while fixing the other horizontal portion from the inside minimizes the width of the mastic. Furthermore, installation from the outside means that the window may be fitted independently of the position of the vehicle on the assembly line, since whether the interior fittings have been fitted or not is of no importance.

Abstract: An improved device and method for mounting an avionic system is shown. The design provides varying locations of key components, which allows a single mounting system to be used with several varieties and configurations of aircraft within the crowded confines of an instrument panel. Ranges of flexibility with this system include the ability to arrange modules horizontally, and the ability to locate the display unit vertically. The multi-dimensional mounting flexibility of the mounting system shown allows electronic modules to be mounted in close proximity to a display unit, which greatly increases accessibility of the modules over prior configurations where modules were housed in the nose of the aircraft, the rear of the aircraft, or other remote locations. Installation, repair, and replacement are all greatly simplified with this configuration.

Abstract: In a motor case 1, recesses 8 are formed in inner surfaces of upper and bottom surface portions 2 and 3 (which are spaced from each other by a distance smaller than the distance between left and right side surface portions 4 and 5), thus reducing the thickness of these surface portions 2 and 3, thereby increasing a space for receiving a stator coil 10 as much as possible. Unlike a construction in which a stator coil is exposed through openings formed in a motor case, the stator coil is covered with the motor case, and therefore the motor is excellent in shielding performance and impact resistance. The motor case 1 has a square tubular shape, and can be formed by blanking, press-forging (for the purpose of forming the recesses) and bending a metal sheet, and the motor case can be produced at a low cost.

Abstract: The present invention features a method wherein a component in a multi-head component placement machine is rejected during the placement cycle. A component is imaged and the image processed using an automated vision system. The image processing determines whether the component is placeable based upon a comparison of the component image to preprogrammed mechanical parameters for the component. A non-placeable component is rejected into a reject station, which is contiguous with the head. Because a component can be rejected during the placement cycle, there is no slowdown of the placement machine cycle rate.

The cavity furthermore has an internal wall with at least one region made of an initial material (for example, silicon). A metal is deposited close to the region of initial material. The circuit is then heated to form a portion of the compound material (for example, a silicide) in the region of initial material inside the cavity.

The excess metal that has not formed some of the compound material is then removed from the cavity.

Abstract: Conductive paste containing tin particles and silver particles is packed in a substantially cylindrical via hole formed in a thermoplastic resin film that interposes between conductor patterns and is hot-pressed from both sides. When the metal particles contained in the conductive paste are sintered to form a unified conductive compound, the volume of the conductive paste shrinks. Synchronously, the resin film around the via-hole protrudes into the via-hole. Therefore, the shape of the side wall on the cross-section of the conductive compound provides an arch shape, and a side wall adjacent to a junction part of the conductive compound, which contacts the conductor pattern, is formed with an inclination. Therefore, it is possible to prevent the stress concentration due to deformation of the board.

Abstract: A method of producing an ink jet printhead with 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.
