Abstract:
PURPOSE: An apparatus and method for clinching a plate are provided to clinch heterogeneous materials or homogeneous materials through a local interface bonding process, thereby improving a bonding force between the materials. CONSTITUTION: An apparatus for clinching a plate includes an anvil (100), a lower plate (200), an upper plate (300), and a chamber (400). The anvil includes a cartridge heater inside. The lower plate is mounted on the anvil. The upper plate is laminated on the lower plate. The chamber is separated from the anvil at a certain distance, and is installed at the upper side of the anvil. The chamber includes an induction coil, a punch, a cooling pipe, a clamp, and an insulating member.
Abstract:
PURPOSE: A composition for enhancing the size of plant seeds or storage fat content in the seeds is provided to enhance seed yield and productivity. CONSTITUTION: A composition for enhancing the size of plant seeds or storage fat content in the seeds contains ABC(ATP-binding cassette) transporter protein or a gene encoding the same. The protein is a polypeptide having an amino acid sequence of sequence number 1. The gene has a base of sequence number 2. The composition contains the gene, a transformation vector having a promoter for overexpressing the gene, or a microorganism transformed by the vector. A method for enhancing the size of the seeds or storage fat content in the seeds comprises a step of transducing the gene and promoter into a plant body.
Abstract:
A server-client screen sharing system applying a screen sharing device using UWB is provided to use a radio transmission type through UWB(Ultra Wideband), thereby being easy to install, manage, and use compared with an existing wire system as a place applied is wide and a number of clients is many. In a server-client screen sharing system, a server-sided computer comprises a UWB band converter and a server-sided RF(Radio Frequency) transceiver. The UWB band converter converts a video signal of a predetermined band into a UWB signal. The server-sided RF transceiver transmits the band-converted video signal by wireless and receives data received from a client. The client side comprises a client-sided RF transceiver and a UWB reverse-band converter. The client-sided RF transceiver receives the video signal of which the band is converted into UWB by wireless, and transmits client-sided data to a server. The UWB reverse-band converter performs the reverse-band conversion of the UWB video signal into the band of the predetermined video signal.
Abstract:
The present invention relates to a composition for increasing the lipid content of microalgae or microorganisms comprising a sterol synthesis inhibitor, and more specifically, to a composition for increasing the production efficiency of lipid which can be used as bioenergy by increasing the lipid content of microalgae or microorganisms. The microalgae has very low lipid content in a regular condition with abundant nutrients, and synthesizes lipid in a stressful condition like nutrition deficiency after stopping the growth, thereby having a limit of using the lipid contained in the microalgae as a bioenergy source. The composition of the present invention overcomes the said properties of the microalgae, and is expected to be crucially utilized as the bioenergy source.
