摘要:
A diesel engine piston having a combustion chamber may include a profile surface that protrudes toward a center axis of the combustion chamber from an inner wall thereof and includes a protrusion on the inner wall, the protrusion extending from the inner wall with a predetermined length, wherein the protrusion divides a spray fuel, which may be sprayed and atomized onto the protrusion, into a fuel flow at an upper portion of the combustion chamber and a fuel flow at a lower portion of the combustion chamber, respectively.

A diesel-gasoline hybrid engine is constructed with an exhaust gas recirculation (EGR) system, without a design change. As a combustion space of a combustion chamber is stratified into a high-concentration EGR space and a relatively low-concentration EGR space, an ignition quality of a low-speed and low-load region is secured to improve combustion, and simultaneously, knocking in a high-low region is suppressed. Furthermore, the amount of NOX generated during gasoline premixed combustion and smoke generated during diesel combustion are significantly reduced.

A multi-sac injection includes a main sac located at the center of a nozzle such that an injected fuel formed a low load cone angle to inject a fuel for pre-mixed combustion, and sub-sacs located at sides of the nozzle such that the injected fuel forms a middle/high load cone angle large relative to a low load cone angle to inject a fuel for diffusive combustion. Accordingly, smoke and NOx are significantly reduced in a low load region while maintaining features of a middle/high load region with a single injector.

A thin film transistor (TFT) and a method of fabricating the same, in which a fabrication process is simplified and damage to a gate insulating layer is decreased. The method of fabricating the TFT includes forming at least one buffer layer on a substrate, forming a first semiconductor layer formed on the buffer layer and a second semiconductor layer by depositing a semiconductor doped with a dopant on the first semiconductor layer, patterning the second semiconductor layer to form source and drain regions, forming a gate insulating layer on the source and drain regions, and forming a gate electrode on the gate insulating layer.

Disclosed is a conductive polarizer for an LCD. The conductive polarizer includes a protective layer, an adhesive layer deposited on the protective layer, a lower support layer deposited on the adhesive layer, a polarizing layer deposited on the lower support layer, an upper support layer deposited on the polarizing layer, and an anti-glare/anti-static layer deposited on the upper support layer. The anti-glare/anti-static layer includes an antimony tin oxide layer formed at an upper surface thereof with a conductive polymer pattern for inducing static electricity and an anti-reflective layer formed on the antimony tin oxide layer including the conductive polymer pattern. Silica particles are distributed over a whole area of the anti-reflective layer.

Disclosed is a micro power cell capable of being applied as an energy source and utilizing a streaming potential phenomenon occurring in accordance with an electrokinetic principle when an electrolyte aqueous solution flows in the microchannels piled up in several layers. The streaming potential cell consists of a PDMS microfluidic-chip fabricated by MEMS process as well as micromachining technology. The microfluidic-chip is formed with multi microchannels radially arranged in parallel with each other around a center of a disk at a regular interval. The disk type multi microchannel can achieve uniform inflow and outflow effects. According to the invention, there is provided a cell device comprising a pile-up chip having a number of disk type microfluidic-chips with the optimal structure of flow-in and flow-out of a fluid, a distributor, a collector, an electrode insertion part, etc.

A method and system for providing resources by using a virtual path are provided. The method includes: extracting comparison client information corresponding to a virtual path policy from a client that wants to access a resource server and has logged in through a virtual path that is generated so that the resource server is accessed through a virtual path server; comparing the comparison client information with original client information that is already stored in the virtual path server; and if the verification is successful, providing resources to the client that wants to access the resource server through the virtual path. Accordingly, without a separate login verification procedure, basic security can be supported only with the virtual path. Also, according to a security policy, a flexible login verification procedure can be enabled, and misuse and abuse, such as illegal linking to resources, can be properly handled.
摘要:
Fermented wines made from fruits of deciduous shrubs or latifoliate shrubs in the family of Aralia elata, especially, fruits of Acanthopanax sessiliflorous or Acanthopanax senticosus, and a producing method thereof. These fermented wines are much milder than traditional liquors made from roots or stems of Acanthopanax. The method of utilizing fruits of Acanthopanax, that otherwise have traditionally been discarded, results in increased economic benefit by helping increase usage of farm yields.
