Abstract: An image sensor with a high dynamic range is provided. The image sensor includes a semiconductor substrate, a plurality of light-receiving elements formed on the semiconductor substrate, and light-shield films formed on upper ends of some of the light-receiving elements to partially block light incident upon each of the some light-receiving elements. Hence, an image sensing device including the image sensor can detect an accurate image regardless of whether the environment is bright or dark.

Abstract: Disclosed is a method and apparatus for producing a microchannel plate (MCP) using a corrugated mold, characterized in that each of corrugated substrates formed by the corrugated mold is coated with a secondary emitter and then layered, thereby easily producing a large area of the MCP and decreasing production costs of the MCP. The MCP producing method includes placing a first flat substrate on the corrugated mold, vacuum forming the first flat substrate so that both surfaces thereof are corrugated, coating a secondary emitter onto both surfaces of each of the first corrugated substrate and a second flat substrate, and alternately layering a plurality of the first corrugated substrates and a plurality of the second substrates each coated with the secondary emitter, to form microchannels.

Abstract: An apparatus for fabricating a liquid crystal display panel includes a chamber for holding a substrate, wherein the substrate includes first and second metal patterns, a spray nozzle connected to the chamber for spraying spacers onto the substrate, wherein the spacers are charged with a predetermined polarity, and a first power supplier connected to the chamber for applying a first voltage with a positive polarity and a second voltage with a negative polarity to the first and second metal patterns of the substrate.

Abstract: A robot arm has an impact absorption structure for absorbing impact energy caused by a collision to protect a person from injury and the robot arm from being damaged. The robot arm includes a plurality of rigid beams provided at both end portions thereof to define a frame of the robot arm, and side members made of an elastic material and provided between the plurality of rigid beams to define an appearance of the robot arm and absorb the impact energy. Each side member includes a sheet made of a plastic material, a foam or honeycomb structure, and a fiber reinforced composite material attached to the sheet.

Abstract: A source-gas supply apparatus for supplying a source gas into a CVD reactor includes: a reservoir for storing a liquid material; a gas flow path connected the reservoir and the CVD reactor; a sonic nozzle disposed in the gas flow path, through which the source gas is introduced into the CVD reactor; a pressure sensor disposed in the gas flow path upstream of the sonic nozzle; a flow control valve disposed in the gas flow path upstream of the pressure sensor; and a flow control circuit which receives a signal from the pressure sensor and outputs a signal to the flow control valve to adjust opening of the flow control valve as a function of the signal from the pressure sensor.
