Title: Combustion chamber for auxiliary chamber type internal combustion engine
Inventor: IMOTO KOJI
IPC: F02B19/14
Filed: 1996-09-04
Abstract: PROBLEM TO BE SOLVED: To reduce fuel consumption and satisfactorily ensure or improve smoke discharge by protruding a tip part of an auxiliary chamber base into a main combustion chamber, and providing a recessed part at an upper face inlet part of a cavity. SOLUTION: Air in a main combustion chamber 1 compressed by a piston 6 flows into an auxiliary chamber 2 through an auxiliary chamber nozzle hole 3. Since the main combustion chamber 1 side opening end of the auxiliary chamber nozzle hole 3, and a tip part 8a of an auxiliary chamber base 8 are protruded into the main combustion chamber 1, gas jet flowing into the auxiliary combustion chamber 2 from the main combustion chamber 1 through the auxiliary chamber nozzle hole 3 does not interfere with the lower face 4a of a cylinder head 4, so that this gas jet is mixed with fuel injected into the auxiliary combustion chamber 2 from a fuel injection valve 5 so as to accelerate combustion.  In addition, a recessed part 10 is provided at the upper part of a side wall 6b of a cavity 6a, so that unburnt-burnt gas jet 20 from the auxiliary combustion chamber 2 flows to both sides of a top clearance part so as to accelerate fuel-air mixing and combustion in the main combustion chamber 1.

IPC: G06T7/00
Filed: 1999-09-08
Abstract: PROBLEM TO BE SOLVED: To provide a reference image preparing method capable of preparing an optimum reference image, a pattern recognizing method using it and a recording medium. SOLUTION: This reference image preparing method uses a pattern recognizing device 1 and acquires an SEM image representing a pattern on a wafer 41 by a SEM 10. The method performs data processing of the SEM image, calculates a parameter showing the height degree of pattern characteristic property in each area of a prescribed reference size and extracts the prescribed number of areas where a pattern is large and the pattern whose characteristic property is high is included. An image of an area whose parameter is the largest is defined as a candidate image to be a candidate for a reference image, and a correlation coefficient representing the highness and lowness of the similarity with images of the other areas is calculated in each of the other reference size areas.  The calculated correlation coefficient is compared with a preliminarily defined threshold, when an area having a correlation coefficient being equal to or more than the threshold exists, the candidate image is discarded, and the image of an area whose parameter is the next largest is defined as a new candidate image. These procedures are repeated until an area that is equal to or more than the threshold does not exist any more.
