IPC: G01B11/24
Filed: 1999-01-07
Abstract: PROBLEM TO BE SOLVED: To accurately and stably recognize an object which has an approximate circular and elliptic shape. SOLUTION: A detecting window W consisting of an external frame W2 enclosing an image of an adhesive 40 coated and an internal frame W1 inside the image enclosed with the contour line of the adhesive 40 is set.

Abstract: PURPOSE: To reduce non-return load that will act on a starting system even when a kick-back occures so as to secure a guarantee of strength of the starting system, by forming a one-way clutch interposed in the starting system into a ratchet type. and setting the meshing position of said clutch within a specified crank angle range.  
     CONSTITUTION: The starting system 12 includes a gear mechanism 17 that connects a starting shaft 11 via an intermediate shaft 15 to a follow shaft 16, a chain mechanism 18 and the one-way clutch 19 that connects a shaft 16 with a crank shaft 8. The clutch 19 is a ratchet type, and its meshing position, when the shaft 11 is in the non-driving position, is set in the range of a crank angle between a bottom dead point A and a position that makes 20° from a valve closing point B toward a top dead point C. Due to said mechanism, the non-return load of the shaft 8 actuated by the clutch 19 generates at the times when the shaft 8 is impacted by the compression reaction of the piston 5 being located in the vicinity of the top dead point C, or when the shaft 8 is impacted by the reverse rotation caused by the kick-back. The internal pressure of the combustion chamber, however, in the case of kick-back impact, is gradually reduced due to the descending motion of the piston 5, thereby decreasing the non-return load.
