IPC: F02B37/12
Filed: 2000-01-28
Abstract: PURPOSE: A turbo charger using a variable exhaust pressure adjusting valve is provided to apply a path to all areas of low, mid and high loads by adjusting the path depending on the area of exhaust pressure by a variable valve. CONSTITUTION: An intake pipe(7) and an exhaust pipe(4) are mounted in a combustion chamber(1) of an engine. A compressor(5) and a compressed air cooler(6) are installed on the intake pipe. A turbine(3) is set in the exhaust pipe to be operated by exhaust gas. An exhaust pressure adjusting valve(2) is controlled by an exhaust pressure sensor(8) and an adjusting valve controller(9). The valve opens/closes an exhaust gas discharge path including each exhaust gas discharge path(12,13,14) at low, mid and high load respectively. Exhaust gas is discharged through the exhaust pipe from the combustion chamber. A valve plate is rotated by a command of the adjusting valve controller, referring to data measured from the exhaust pressure sensor. Thereby, one of the plural exhaust gas discharge paths for each low, mid and high load is selected. The exhaust gas is discharged through the selected exhaust gas discharge path and then through the exhaust pipe with rotating the turbine. The compressor connected with the turbine sucks, compresses and blows air to a cooler(6). Therefore, the cooled air is supplied to the combustion chamber through an intake port.

Title: Method for layout of semiconductor interconnection
Inventor: CHOI JUN HO
IPC: H01L27/04
Filed: 2000-01-31
Abstract: PURPOSE: A layout method of a semiconductor metal interconnect line is provided to improve a lifetime of the interconnect line by mitigating a hydrostatic stress concentrated on a steep bending part of the interconnect line. CONSTITUTION: A prolonged interconnect line(12) is prolonged along one direction of a steep bending part of a main interconnect line(11). That is, a steep bending part is prevented to remove a hydrostatic stress. Therefore, the structure of the vertical interconnect line is varied to a T-shaped one. Even when the main interconnect line has a U-shaped form, a steep bending part is prevented by forming the prolong interconnect line along one direction at a part crossing the main interconnect line vertically. The layout method thus can prevent an open of the interconnect line by preventing the generation of a void due to the stress.
