摘要： The present invention relates to a manhole cover which has an upper body and a lower body coupled to each other to maintain balance, to endure loads applied from an external source in a stable manner, to protect the inside of the manhole from the ingress of rainwater, and to enable the upper body to be stably fixed inside the lower body. To accomplish the above-described aim, the key technical features of the present invention relate to a manhole cover, comprising: a lower body, the inside of which is hollow, with a spiral rib formed along the inner surface of the hollow space, and a convex-concave portion formed on the upper surface of the spiral rib; an upper body which is coupled inside the lower body, and the inside of which is hollow, with a spiral rib and a convex-concave portion formed along the outer surface thereof to correspond to the spiral rib and the convex-concave portion of the lower body, and a stepped portion formed at the upper surface thereof; a cover mounted in the stepped portion of the upper body to protect the inside of the upper body from the introduction of foreign objects; and a waterproofing means removably arranged inside the upper body to protect the inside of the manhole from the ingress of rainwater.

摘要： The present invention relates to a method of forming a small gap using CMP and a method for manufacturing a lateral FED. In the present invention, a small gap is determined by the thickness of an oxide film, and so uniform small gaps of about 100 Å that have been impossible to attain with the art of prior lithography can be formed with repeatability. Prior lateral field emission devices have the problem of repeatability in forming a gap for field emission because they are fabricated by means of a thermal stress method or an electrical stress method. But if the method of forming a small gap according to the present invention is used to fabricate a lateral FED, a FED can be made that has low voltage drive and high current drive characteristics and uniform field emission characteristics.
摘要翻译：本发明涉及使用CMP形成小间隙的方法以及制造横向FED的方法。在本发明中，通过氧化膜的厚度来确定小的间隙，并且可以以重复性形成与现有技术的光刻技术无法达到的均匀的约100的小间隙。现有的横向场发射装置在形成用于场发射的间隙的重复性方面存在问题，因为它们是通过热应力法或电应力法制造的。但是，如果使用根据本发明的形成小间隙的方法来制造横向FED，则可以制造具有低电压驱动和高电流驱动特性以及均匀的场发射特性的FED。

摘要： Disclosed herein is a power cable capable of detecting failure. The power cable in accordance with one embodiment of this invention includes a conductor, and an auxiliary line which is inserted into an inner layer provided between the conductor and an outermost layer and is installed to extend in a longitudinal direction in a spiral arrangement. The auxiliary line is made of an optical fiber, and the thickness of the auxiliary line is determined so that the auxiliary line is cut or deformed by a force sufficient to cause damage to the power cable. Preferably, pitch of the auxiliary line is 30mm or less. Further, the inner layer corresponds to an anti-corrosive layer which is formed to protect against external impact or corrosion, or a polyethylene sheath which covers an insulator covering the conductor.

摘要： PURPOSE: An apparatus for removing snow from a driving range net is provided to effectively economically remove snow by being additionally installed at an existing driving range. CONSTITUTION: An apparatus for removing snow from a driving range includes a snow removing assembly(200), and a supporting unit for the assembly, and a conveyor. The snow removing assembly is installed at the lower side of the bottom of a net in order to cross the transversal direction of the bottom of the net. The supporting unit supports the assembly to be approached to the lower side of the bottom of the net. The conveyor is connected with both sides of the assembly such that the assembly sweeps the lower side of the bottom of the net and moves along the moving direction of a struck golf ball.
