摘要： In a surface-mount type antenna, a substantially-rectangular solid base body has a feeding terminal and a ground terminal formed on its one side surface. A radiating electrode has its one end connected to the ground terminal and is disposed helically across the surfaces of base body extending from one side surface to one principal surface. Another end of radiating electrode extends from one principal surface, through another side surface, toward another principal surface, to form a wide-area portion facing the feeding terminal. An antenna apparatus is constructed by mounting the surface-mount type antenna on a mounting substrate having formed thereon a feeding electrode, a ground electrode, and a ground conductor layer, and simultaneously connecting the feeding terminal and the ground terminal to the feeding electrode and the ground electrode, respectively.

摘要： It is an object of the invention to provide a meander antenna that is smaller and lighter, in which the resonance frequency easily can be tuned, as well as a method for tuning its resonance frequency. The meander antenna comprises a meandering conductor on the surface of a substrate. The meander antenna is provided with a short-circuit conductor line that forms a short-circuit between two parallel opposing lines into which the conductor is bent, or an open conductor line in which a line short-circuiting the two parallel opposing lines is open. The resonance frequency can be tuned and lowered by cutting open the short-circuit line or increased by short-circuiting the open conductor line.

摘要： Spacers used in a picture display device are formed of a sintered product having a structure in which at least one kind of metal selected from the group consisting of Si, Zn, Al, Sn, Cu and Mg is dispersed in a glass. In the picture display device using spacers, therefore, the spacers are effectively prevented from being electrically charged and, besides, trouble such as distortion in the displayed picture caused by the electric charge in the spacers is effectively prevented, too. In producing the spacers by firing, further, the volume expands due to the oxidation of the metal component, whereby shrinkage due to firing is effectively relaxed, making it possible to produce the spacers maintaining a high dimensional precision. Besides, the spacers are effectively prevented from being deformed by the shrinkage caused by firing.
摘要翻译：在图像显示装置中使用的间隔物由具有将从Si，Zn，Al，Sn，Cu，Mg中选出的至少一种金属分散在玻璃中的结构的烧结体形成。因此，在使用间隔物的图像显示装置中，有效地防止了间隔物的带电，并且还有效地防止了由间隔物中的电荷引起的显示画面的变形等故障。此外，在通过烧制制造间隔物的过程中，由于金属部件的氧化，体积膨胀，由此烧成的收缩被有效地松弛，从而可以制造保持高尺寸精度的间隔物。此外，通过烧成引起的收缩，有效地防止间隔件变形。
