摘要： One example of a high-frequency filter includes a dielectric substrate having a high dielectric constant. On one whole main face of the dielectric substrate, an earth electrode is formed. On the other main face of the dielectric substrate, two pattern electrodes are formed. The pattern electrodes have first parts formed in parallel at an interval, and second parts extended in crossing (non-parallel) directions. Also, on one main face of the dielectric substrate, input-output electrodes are respectively formed near the end parts of the pattern electrodes, and capacitors are respectively formed between the open end parts and the input-output electrodes.

摘要： The ground surrounding a liquified gas storing underground tank is excavated into a form of a columnar cavity or wall shaped cavity, and then a synthetic resin bag or envelope is placed therein, after which granular materials such as sand or gravel is filled therein, thus forming a water permeable body of a columnar shape or wall-like shape. Then, water is injected into the water permeable body from its bottom and then discharged from the top of the body, thereby warming the peripheral ground of the underground tank for preventing freezing thereof. An apparatus for preventing the freezing of a liquified gas storing underground tank is also disclosed, which includes water feeding and discharging devices provided for the aforesaid water permeable body.
摘要翻译：围绕液化天然气储存地下储罐的地面被挖掘成柱形腔或壁形空腔的形式，然后将合成树脂袋或信封放置在其中，之后填充诸如砂或砾石的颗粒材料，从而形成圆柱状或壁状的透水体。然后，水从其底部注入透水体，然后从身体的顶部排出，从而使地下罐的周边地面变暖，以防止其冻结。还公开了一种用于防止液化气储存地下储罐冷冻的装置，其包括为上述透水体提供的给水和排放装置。
