    摘要： An intake system for an internal combustion engine, having a structure in which blow-by oil and/or fuel entering into an air cleaner case can be discharged to the outside of the air cleaner case. The intake system for an internal combustion engine is provided in which air is sucked from a clean air chamber in the air cleaner case into a throttle body provided with a throttle valve through a funnel while defining an airflow passage. Concurrently, fuel is sprayed from an injector, thereby feeding the fuel-air mixture into an intake port. A bypass passage different from the airflow passage is provided between the clean air chamber in the air cleaner case and the throttle body. The bypass passage is so structured that a passage inlet thereof on the clean air chamber side opens at an inner wall surface of the air cleaner case.

    摘要： This invention provides a method for producing a ceramic catalyst body that can directly support a catalyst on a ceramic support without disposing a coating layer on the ceramic support. In the invention, a catalyst solution containing a catalyst component consisting of a negative complex ion resulting from a catalyst precursor is prepared, and a pH of the catalyst solution is adjusted in such a manner as to satisfy the relation E1>E2 and E1>0 where E1 is a surface potential of a matrix phase consisting of a cordierite-W composite body relative to the pH of the catalyst solution and E2 is a surface potential of a dispersed phase consisting of compounds other than the cordierite-W composite body. After the ceramic support is brought into contact with the catalyst solution to support the catalyst component, heat-treatment is conducted to bond the matrix phase consisting of the cordierite-W composite body and the catalyst component to support the catalyst on the ceramic support.

    摘要： To realize an equivalence verification between an analog circuit and its function model unit. From a circuit topology and a functional description, there is extracted contained in the circuit. A test circuit capable of inputting a verification vector according to the extracted circuit function is created, and a verification is made to provide a result. In case the equivalence is to be verified, a similar verification is made by replacing only a compared circuit of the test circuit created. After the result was obtained, its difference from the aforementioned result is made. If this difference is within an allowable range, the equivalence is decided. By using the configuration of the invention, the analog circuit or the function model can be verified on itself. Moreover, the equivalence can be verified with the minimum configuration.

    摘要： This invention aims at achieving early activation by use of a catalytic body having a low thermal capacity, and a low pressure loss, without using a coating layer to reduce exhaust emission. The invention is directed also to improve exhaust purification performance by improving the combination of catalytic bodies and performance of each catalytic body. In the invention, a start catalyst 1 is arranged at an upstream portion of an exhaust pipe P of a car engine E and a three way catalyst 2 is disposed on the downstream side. The start catalyst 1 can directly support catalytic components through chemical bonds by incorporating replacing elements into a substrate ceramic having high heat resistance such as cordierite. Because a coating layer is not necessary, the catalyst of the invention has a low heat capacity and a large open area and achieves reduction of exhaust emission, and reduction of a pressure loss, through early activation.
