    摘要： A method of fabricating a micro-vertical structure is provided. The method includes bonding a second crystalline silicon (Si) substrate onto a first crystalline Si substrate by interposing an insulating layer pattern and a cavity, etching the second crystalline Si substrate using a deep reactive ion etch (DRIE) process along a [111] crystal plane vertical to the second crystalline Si substrate, and etching an etched vertical surface of the second crystalline Si substrate using a crystalline wet etching process to improve the surface roughness and flatness of the etched vertical surface. As a result, no morphological defects occur on the etched vertical surface. Also, footings do not occur at an etch end-point due to the insulating layer pattern. In addition, the micro-vertical structure does not float in the air but is fixed to the first crystalline Si substrate, thereby facilitating subsequent processes.

    摘要： Provided is a multi-layer restoration method using a LCAS (Link Capacity Adjustment Scheme) in a synchronous network having a mesh structure. The method includes: performing a hardware restoration method if a network failure is detected; performing a pre-planned restoration method if the network failure is not repaired by performing the hardware restoration method; determining whether channels that pass along a line where the network failure occurs use the LCAS if the network failure is not repaired by performing the pre-planned restoration method; and applying the LCAS to the channels if the channels are determined to use the LCAS, and performing a dynamic restoration method if the channels are not determined to use the LCAS. The multiplayer restoration method minimizes data loss due to an increase in restoration time and overcomes service disconnection caused by failure to obtain a spare channel.

    摘要： A separating plate for a fuel cell includes first and second plates, each provided with a hydrogen channel, an oxygen channel, and a coolant channel. The first and second plates are attached to one another to form a main plate such that the first and second hydrogen, oxygen, and coolant channels compose main hydrogen, oxygen, and coolant channels, respectively. The main hydrogen and oxygen channels are fluidly isolated from each other. Distal ends of the main channels each communicate with a manifold through a communication passageway configured to supply hydrogen, oxygen, or coolant to a corresponding one of the main channels.
