Abstract: In a conventional micro-channel plate (MCP), a secondary electron (SE) detector or a semi-conductor detector the number of the electrons is amplified through its own structure. For such amplification a small voltage difference is applied externally or generated due to its own structure and material. The electric current of electrons undergoing the above-described procedure is amplified by an external amplification circuit. In the present invention electrons—resulting from the collision of the electron beam generated by a microcolumn—are detected by surrounding conductive wiring. The detected electrons are amplified using an amplification circuit on the outside similar to a conventional detection method.

Abstract: The present invention relates to an X-ray imaging apparatus comprising an X-ray source unit generating an X-ray, an X-ray detecting sensor unit having a sensor panel equipped with multiple sensors detecting the X-ray which is generated from the X-ray source unit and passed through an object, and a panel-moving means mounted on the X-ray detecting sensor unit and moving the sensor panel. Thus, employing and butting multiple small X-ray sensors instead of expensive large sensors advantageously reduces the manufacturing cost for the X-ray imaging apparatus, and enables the imaging of the same wide area as with the use of the large sensors.

Abstract: Disclosed is a half moon type net for catching balls or flexibly stopping the flight of balls, comprising a half-moon-shaped or arch-shaped loop and a fabric retainer to better support the net structure, maintain a bigger net in shape, and reduce the chance of missing balls. More specifically, the net comprises: a main member forming a substantially half-moon-shaped closed loop; a base member forming a closed loop, wherein the straight front section of the base member is connected to the straight bottom section of the main member; a fabric retainer comprising two bottom sections formed adjacent to each of the two corners of the main member and an arch section along the top section of the main member so as to maintain the main member in shape; a fabric member covering the loop of the main member to flexibly stop the flight of projectiles; and a supporting member to sustain the main member against the base member while maintaining a substantial angle between the main and base members.

Abstract: Provided are a gasket, a reactor using the same for sealing a spiral, and a manufacturing method thereof. Spirials are continuously installed in the longitudinal direction between an inner pipe and an outer pipe coaxially arranged to form a flow path for a heat medium, so the seal between the spiral and the outer pipe is stably maintained and fabrication of the reactor is facilitated. The gasket is inserted in and coupled with the spiral, and thus does not need additional processing for combining the gasket. The gasket and spiral are coupled by lodging the spiral into a channel of the gasket. Furthermore, since the gasket is evenly coupled in the outer circumference of the spiral, in which a cushion plate made of resilient material is installed, breakage of the gasket during assembly of the outer pipe is effectively prevented and the post-assembly seal between the spiral and the outer pipe is stabilized.

Abstract: A single loop net includes a loop member, triangular holders, side straight edge portions, two propping poles, two holding straps, a first opening, a catching net, net deploying straps, and a second opening. The triangular holders are for holding two neighboring straight portions. The side straight edge portions are fixed to one of the side straight portions. Each of the propping poles extends from two side straight portions of the loop member. Each of the holding straps extends from a lower portion of the loop member. The first opening is enclosed and defined by the triangular holders and the side straight edge portions. The catching net covers the first opening and configured to catch balls flying into the first opening from a frontal direction. The second opening is disposed in a bottom one of the side straight edge portions. The second opening is disposed so as to return balls.

Abstract: A three-axis antenna positioner has an X-Y over azimuth configuration, and includes an azimuth drive assembly, an X-axis drive assembly, and a Y-axis drive assembly. Each drive assembly is independently operable. The azimuth drive assembly imparts 540° azimuthal rotational motion to an antenna about an azimuth axis. The X-axis drive assembly rotates the antenna about a horizontal X-axis at elevation angles between ?90° and +90°. The Y-axis drive assembly rotates the antenna about a Y-axis at elevation complement angles between ?2° and +105°. The azimuth axis, the X-axis, and the Y-axis all intersect at a common intersection point, and are mutually orthogonal. A controller operates each drive assembly so as to minimize antenna tracking velocity and acceleration. Each drive assembly may include dual drives, and may be operated in a bias drive mode to substantially eliminate backlash.

Abstract: The present invention relates to an electrostatic speaker including a fixed electrode and a diaphragm that is arranged with a predetermined gap from the fixed electrode and has a plurality of ventilation holes. The ventilative diaphragm reduces air resistance caused by the ground effect between the fixed electrode and the diaphragm, and increases the sound pressure output from the speaker. As a result, the ventilative diaphragm makes it possible to obtain a uniform frequency reproduction characteristic over the entire frequency range. In particular, when the diaphragm is made from Korean paper, it is possible to effectively reduce the ground effect occurring between the fixed electrode and the diaphragm due to the air permeable characteristic of the Korean paper and the air resistance due to a surge input signal, while satisfying physical characteristics of the existing diaphragm. In addition, since the Korean paper has high formability, it is possible to easily form the diaphragm in a hemispherical shape.
