Patent JP-H05231208-A (JP)
Title: Exhauster for internal combustion engine
Inventor: IIZAKA SHIGEMITSU
IPC: F02D35/00
Filed: 1992-02-20
Abstract: PURPOSE:To apply exhaust gas flow uniformly to an oxygen concentration sensor by arranging an oxygen concentration sensor near the confluent portion of a confluent tube provided for a number of exhaust gas branch tubes and also switching a plurality of exhaust gas introduction ports, which are formed downstream from the confluent tube, from open to close or vice versa in response to the flow rate of exhaust gas. CONSTITUTION:The downstream portions of a number of exhaust gas branch tubes 2 to 5 in an exhaust manifold 1 are made confluent in a single confluence tube 6. An O2 sensor 7 is then arranged near the confluent portion of the confluence tube 6. Further, a plural number of exhaust gas introduction ports 8, 9 for EGR are formed downstream from the sensor 7. Each of exhaust gas introduction port 8, 9 is selectively switched in response to the exhaust gas flow rate whereby exhaust gas from each cylinder is applied uniformly to the sensor 7. For example, when exhaust gas flow rate is low, exhaust gas staying in the confluence tube 6 is introduced from a first introduction port 8. Thus the flow courses of exhaust gas inside first and fourth exhaust tubes 2, 5, respectively, are changed in the directions departing from the sensor 7 and these of exhaust gas inside second and third exhaust tubes 3, 4 are changed in the directions accessing the sensor 7.

Abstract: PROBLEM TO BE SOLVED: To improve the resistance of a silicon nitride film against peel off, in a semiconductor device in which a silicon oxide film in which an oxygen- silsesquioxane resin film is made ceramic is formed below the silicon nitride film as a surface protective film. SOLUTION: Wiring layers 20a to 20c or the like are formed on the surface of a semiconductor 10 through insulating films 12 and 16. After this, the top surface of the substrate is spin-coated with a hydrogen-silsesquioxane resin film, and is heat-treated to form a ceramic silicon oxide film 32. Since the film 32 has a low dielectric constant, it helps to decrease the inter-wiring capacitance. After a silicon oxide film 33 is formed on the film 32 through a plasma CVD method, a silicon nitride film 34 is formed on the film 33 by the plasma CVD method. The film 33 has practically full bonding characteristics with respect to either of the film 32 or the film 34.
