摘要： A five axis motion controlled ultra-precision machine tool is provided in which major portions are composed as a structure completely symmetric about the machining point and errors due to thermal displacement can be minimized. A pair of Y axis guide members (41,41) are secured to the top face of a base (i) at both sides of an X axis slider (3) interposed therebetween for X direction so as to movably guide Y axis sliders (4,4) in horizontal Y direction perpendicular to X axis. Y axis linear motors (42,42) and the Y axis guide members (41,41) are disposed substantially at the center of mass of the Y axis sliders (4,4) respectively, so that the Y axis sliders (4,4) can be driven in Y direction with vibration and errors in alignment minimized.

摘要： The present invention provides a patch antenna having a dielectric layer that is composed of one dielectric film, has one or more holes formed therein by punching, and is provided between a patch and a ground plate, and a method of manufacturing the patch antenna. Since the patch antenna uses a dielectric material having a low relative dielectric constant (a low dielectric material), it is possible to reduce the size of a patch antenna and improve productivity.

摘要： An air gap for minimizing a dielectric constant is formed between dielectric blocks having conductor patterns in order to minimize interference between conductor patterns, thereby providing a slim internal antenna that has a wide bandwidth in a low frequency band as well as in a high frequency band. According to the present invention, it is possible to obtain an antenna that simply and quickly obtains desired characteristics by easily adjusting the thickness of the air gap. Further, the internal antenna is formed by layering dielectric blocks that have conductor patterns. Accordingly, while maintaining the interconnection between the conductor patterns, the internal antenna can change resonant frequency thereof into low frequency as compared with an antenna having the same volume of a dielectric. That is, it is possible to effectively reduce the size of an antenna without significantly affecting the characteristics of the antenna.
