Abstract:
A head lamp for a vehicle is provided, which includes a reflector for reflecting light emitted from a light source, a reflection plate for collecting the light reflected from the reflector in an upward direction, a micro-reflection module provided over the reflector to tilt and reflect the light collected by the reflection plate at a desired angle, and an optical lens for irradiating the light reflected from the micro-reflector onto a road surface. The head lamp can implement various beam patterns in accordance with road and surrounding circumferences, and irradiate vehicle information onto a road surface, thereby reducing the dazzle of other drivers of opposite vehicles and improving the field of vision of the driver to improve the safety and convenience.
Abstract:
An alkaline cell having an anode comprising zinc and a cathode comprising manganese dioxide wherein the cathode is located annularly along the inside surface of the cell housing and has a plurality of indentations on the inside of its surface facing the cell interior. Each indentation has a wall defining a channel with an opening thereto running preferably in the direction of the cell's length. The channel and opening facing the cell interior filled with anode material. The cell can have an anode current collector, typically of metal, with at least a portion of its surface extending into the cathode indentation channel. The anode current collector can have a portion of its surface extending from a point within the anode and into the cathode indentation channel through said opening. The cell can include a cathode current collector comprising a sheet of conductive material such as a sheet of metal or graphite placed within the cathode, particularly within thick regions of the cathode. The cathode current collector can be used. in conduction with a conventional single nail anode current collector or in combination with the extended surface anode current collectors of the invention. Such alkaline cells exhibit improved performance, particularly under high power application.
Abstract:
Disclosed herein is a fastening structure which enables objects to be easily coupled to or removed from each other, and which enables the relative positions between the objects to be changed in the longitudinal position of zipper rails. The fastening structure includes a first zipper rail unit which is provided on a planar portion of a first object and has zipper rails arranged parallel to each other, and a second zipper rail unit which is provided on a planar portion of a second object and has zipper rails arranged parallel to each other. While the zipper rails of the first zipper rail unit are individually coupled to the corresponding zipper rails of the second zipper rail unit in a female-male engagement manner, relative positions between the first object and the second object can be changed in the longitudinal direction of the zipper rails.
Abstract:
An apparatus and method of doping ions into a substrate are disclosed and include a process chamber having an inner space in which an ion implantation process is performed, a support unit positioned in the process chamber, supporting a substrate and being electrically connected to a first power source for generating a high frequency pulse, a conductive unit separated from the support unit in such a manner that plasma associated with the ion implantation process is generated between the support unit and the conductive unit, wherein the conductive unit comprises a first etch prevention member preventing the conductive unit from being etched by a source gas used to generate the plasma, and a power port electrically connected to a second power source and generating radio frequency (RF) power applied to the conductive unit.
Abstract:
Semiconductor manufacturing equipment is disclosed and comprises a robot comprising a robotic arm adapted to transfer a wafer from a wafer cassette in a load lock chamber to a processing chamber with proper alignment and positioning without the need to intermediately pass through a support chamber specially adapted to align and position the wafer.
Abstract:
The performance of alkaline cells comprising a zinc anode and manganese dioxide cathode can be improved, especially in high power application, by applying thermal insulating material to the cell casing. The thermal insulation material can be conveniently applied between the cell label and casing. The thermal insulating material significantly reduces the overall heat transfer coefficient, Uo, for the cell. The insulation increases the internal temperature of the cell during discharge, resulting in better performance.

Abstract:
Disclosed is a lamp assembly providing multiple beam patterns in accordance with traveling conditions of a vehicle. The lamp assembly includes a lamp, a lamp shield driving apparatus blocking a part of light from the lamp by a predetermined shield pattern, a lens condensing the blocked light forward, and a housing accommodating the lamp and the lamp shield driving apparatus. The lamp shield driving apparatus includes a first shield having a predetermined cut off pattern, a second shield overlapping with the first shield and having a different cut off pattern from the first shield, and a driving unit moving either the first shield or the second shield linearly. Two or more beam patterns are formed in accordance with the movement of any one of the shields while the first shield overlaps with the second shield.
Abstract:
A metal gasket for a semiconductor fabrication chamber capable of preventing base plate metal contamination in the chamber, wherein the metal gasket includes a diffusion barrier layer interposed between a base plate and an anti-corrosive coating layer, and wherein the diffusion barrier layer prevents elements of the base plate from being diffused to the anti-corrosive coating layer. Accordingly, the diffusion barrier layer prevents attack on the anti-corrosive coating layer.
