Granted: 1990-11-05
Abstract: Infrared rays fed from the object into the detecting unit are interrupted by a solenoid driven shutter device (14). The detecting unit senses the rays fed from the shutter device through the incident surface, and it outputs a detection value corresp. to the shutter temp. A shutter temp. detecting element (16) directly senses the actual temp. of the shutter device, and it outputs a second detection value corresp. to the actual temp. of the shutter device. The correction coefficient is determined by combining the two values from the detecting unit. Subsequently detected temps. are then corrected by this coefficient.

Abstract: Disclosed is a scanning conversion circuit for a liquid crystal projector. in the liquid crystal projector of half line method, in order to minimize an alias generated when simply converting QT structure into o structure, the scanning conversion circuit using line delay is used as a base circuit. It comprises a brightness/color signal isolation means. By performing isolation of brightness/color signal before line and after line of a reference line by changing the reference line on two lines, a coefficient of a scanning conversion filter is differed in accordance with a even field and odd field. Thereby the isolation of the brightness/color signal and the scanning conversion can be performed.

Title: The structure of semiconductor laser diode
Inventor: KO HYUN-CHOL
IPC: H01S5/30

Granted: 1996-02-24
Abstract: The laser diode includes a substrate (1) with a buffer layer (2) formed on top, a clad layer (3) formed on the intermediate layer, an active layer (4) formed on the clad layer, another clad layer (5) formed on the active layer, intermediate layers (10, 20) formed on the latter clad layer, a current limiting layer(6) and a cap layer (7) formed on the intermediate layers in turn, and a metal electrode(9) formed thereon. The intermediate layer has an energy band gap larger than that of the substrate and smaller than that of the initial clad layer. The intermediate layer is also of the same material as the initial clad layer, but with a different composition. The intermediate layer has a multi-layered structure including a number of layers having different energy band gaps. Intermediate layer reduces series resistance component and makes flow of current smooth. Heat generation is reduced enabling increased output.

Title: Method of forming contact plug using selective tungsten growth
Inventor: CHOI KYUNG KEUN
IPC: H01L21/28

Granted: 2000-05-15
Abstract: PURPOSE: A method for forming a contact plug is to reduce a junction leakage between a silicon substrate and a polysilicon layer by depositing the polysilicon layer in a contact hole after depositing an etching barrier metal. CONSTITUTION: After a contact hole is formed on a silicon substrate(1) and the polysilicon layer(3), an etching barrier metal(5) is deposited on the contact hole. After the second polysilicon layer(6) is deposited on the etching barrier metal, the second polysilicon layer is blanket-etched. Then, a portion of the second polysilicon layer, which is deposited in parallel to the substrate, is removed to expose the etching barrier metal. After an inside of the contact hole is buried with a tungsten plug(7) by selectively depositing a tungsten film in the contact hole, an aluminium alloy(8) is deposited on the substrate. The etching barrier metal is deposited at a thickness of 900 to 1100 angstroms. The second polysilicon layer is deposited at a thickness of 250 to 350 angstroms at a temperature of 550 to 700 deg.C.
