Title: Exhaust emission control device
Inventor: TANAKA MASAICHI
IPC: F01N3/08
Filed: 1994-11-02
Abstract: PURPOSE: To prevent occurrence of malfunction that a valve is imperfectly closed due to adhesion of forein matter such as ruster in exhaust gas to a valve seat of a unidirectional valve in a circulation flow passage for circulating separated HC to an upstream side of a catalyst device by effectively utilizing engine pulsative motions. CONSTITUTION: A valve seat 7a-3 of a unidirectional valve 7a which repeats opening and closing motions by exhaust pulsative motion is arranged in substantially a horizontal manner. Circulated exhaust gas is flowed from a lower to an upper sides in respect to the valve seat 7a-3. Water condensed around the valve seat 7a-3 is dropped downward without being stopped by the valve seat 7a-3. Forein materials are not trapped by the condensed water, and prevented from adhering to the valve seat 7a-3.

Abstract: PURPOSE:To make it possible to perform high speed processing, by using image data in a memory means corresponding to grid points at specified pitch on the image, and selecting a specified grid point as the candidate point of the approximate position of a body. CONSTITUTION:The image of a body to be detected 1 on a background 10 is formed on the image forming surface of an ITV camera 3 having an area sensor 4 through an objective lens 2. The image is transduced into an electrical image signal. The image signal is inputted into an A/D converter 5 and stored in an image memory 6. An image processing part 7 reads the required data out of the image memory 6 and performs position detection. At this time, at first the candidate point of the approximate position of the body to be detected is obtained. Namely, seeking is started at an initial position 0 and sequentially moved toward the peripheral part. When a grid point, which has a specified pitch and brightness exceeding a specified threshold value, is found, this point is made to be the candidate point of the approximate position of a body 9. A mechanical system is usually adjusted so that the body to be detected is located in the vicinity of the center of the field of view beforehand. Therefore, the approximate position is set at a high speed when the initial position is set at the center of the field of view.
