[Title <strong>of</strong> the Invention]<br />

Anchor <strong>for</strong> liquid gas underground tank and tank <strong>for</strong> storage <strong>of</strong> liquid gas<br />

[Claims]<br />

1. Anchor in underground storage tank <strong>for</strong> liquid gas comprising the principal member <strong>of</strong> an<br />

anchor member (10), and metal fixture (11) having cylindrical sealing parts (12) including<br />

the mid section <strong>of</strong> the anchor (10) and flexible support plates (16), wherein the metal fixture<br />

(11) holds the anchor (11) through the holding plate (14) bound to the end <strong>of</strong> the metal<br />

fixture. (See Figure 1).<br />

2. Underground tank and the anchors <strong>for</strong> storage <strong>of</strong> liquefied gas, wherein the bottom plate<br />

(5) is attached to the side walls (3) <strong>of</strong> the tank; its edges has a vertical end face (5b), which<br />

makes contact with horizontal end face (5a) and lower inside surface (3b) <strong>of</strong> the side walls<br />

(3); and the unity <strong>of</strong> this underground storage tank <strong>for</strong> liquid gas is to have the anchors<br />

mounted with appropriate space on the inside <strong>of</strong> the lower part <strong>of</strong> the side walls (3) and the<br />

inside <strong>of</strong> the rim <strong>of</strong> the bottom plate (5). (See Figure 2)<br />

[Excerpt from Detail Description <strong>of</strong> the Invention and Drawings]<br />

This invention pertains to the anchors used in underground storage tank <strong>for</strong> liquid gas and<br />

the underground storage tank <strong>for</strong> liquid gas that utilizes said anchors.<br />

As the anchors used in this manner, publicly known type made <strong>of</strong> steel and extends<br />

between the sidewalls to the tank to the bottom plate. The problem to be solved with this<br />

process <strong>of</strong> attaching the bottom plate to the side walls was that, when a <strong>for</strong>ce is applied in the<br />

direction that would separate the bottom plate and the side walls, the bottom plate moved far<br />

enough away from the side walls, separating the sealing plate, allowing the ground water to<br />

penetrate the tank and freezing inside <strong>of</strong> it.<br />

[Explanation]<br />

The technical fields <strong>of</strong> the specified invention (Claim 1) and related invention (Claim 2) are<br />

an “anchor” and an “underground tank” respectively. Because an “anchor” is used in the<br />

technical field <strong>of</strong> an “underground tanks” in the claims, both inventions are technically and<br />

directly related, and the industrial fields <strong>of</strong> application <strong>of</strong> both inventions are the same.<br />

The anchor that is a new matter corresponding to the problem to be solved <strong>of</strong> the specified<br />

invention is equivalent to the substantial part <strong>of</strong> matters in the claim <strong>of</strong> the related invention.<br />

There<strong>for</strong>e the substantial parts <strong>of</strong> matters in the claims <strong>of</strong> both inventions are the same.<br />
