摘要:
Provided is a target apparatus of high durability so that a thin film is not deformed or damaged under an environment of high temperature and high pressure generated during a nuclear reaction between proton and H218O concentrate, and a productivity of 18F can be increased. The target apparatus includes a cavity member having a cavity, in which H218O concentrate is received, for producing 18F using a nuclear reaction between proton irradiated onto the H218O concentrate in the cavity and the H218O concentrate. The cavity member includes: a front opening and a rear opening facing opposite directions to each other on the irradiation path of the proton, and connected to the cavity so that the cavity can be communicated with the outside; a front thin film and a rear thin film disposed to block the front opening and the rear opening, respectively; and a front reinforcing member and a rear reinforcing member coupled to the cavity member so as to support the front thin film and the rear thin film in order to prevent the front and rear thin films from being swelled due to a pressure rising in the cavity during the nuclear reaction, wherein the front reinforcing member includes a plurality of penetration holes penetrating the front reinforcing member in the irradiation direction of the proton.

摘要:
The present invention relates to an antenna structure in which an antenna pattern is formed on an inner surface of a case of a terminal device, and a method of manufacturing an antenna. In the present invention, an optimal antenna pattern is shaped in accordance with a frequency characteristic of a terminal device and the antenna pattern is directly printed on an inner surface of the terminal device through a vacuum evaporation or sputtering method. At this time, a mask member having the same shape as that of the antenna pattern is further provided. Alternatively, a transfer paper with the antenna pattern printed thereon may be attached to the inner surface of the terminal device. Therefore, even a complex antenna pattern can be easily implemented in the terminal device. Further, an optimal antenna characteristic can be obtained since the antenna is spaced apart from a printed circuit board by a predetermined distance.
