Title: Ceramic valve retaining structure
Inventor: SATO YASUFUMI
IPC: F01L3/10
Filed: 1986-06-12
Abstract: PURPOSE:To prevent a concentrated load from being applied to a stem of a valve which stem is retained through a cotter to a retainer, by setting a diameter of the cotter to be slightly greater than that of the retainer. CONSTITUTION:A valve 1 is mounted in a cylinder head, and a valve member 1a axially upwardly biased by a spring 6 airtightly closes an exhaust passage in cooperation with a valve seat. A cotter 3 abuts against the outer peripheral surface of a stem 1b owing to a wedge effect by the taper of the retainer 4. In operation of an engine, the valve 1 is axially displaced to repeat the engagement and disengagement of the valve member 1a with respect to the valve seat, thereby alternately opening and closing the exhaust passage. In the above construction, an inner diameter of the cotter 3 is set to be slightly greater than an outer diameter of the stem 1b. Accordingly, the inner peripheral surface of the cotter 3 is brought into generally uniform abutment against the outer peripheral surface of the stem 1b, thereby preventing a concentrated load from being applied to the stem 1b.

Abstract: PURPOSE:To measure roughness inside a long slender pipe in a nondestructive manner. CONSTITUTION:A laser beam which is reflected inside a slender pipe 2 in a multiple manner and which is radiated is condensed on a photodetector 40 by a condensing lens 30. The quantity of light of the specular reflection component and the quantity of the scattering reflection component of the laser beam which is radiated from the center-part light-receiving part 41 and the peripheral-part light-receiving part 42 of the photodetector 40 are detected separately. Photocurrents from the central-part light-receiving part 41 and the peripheral-part light-receiving part 42 are input to a signal processing circuit 50. The ratio of the quantity of received light of the central- part light-receiving part 41 to the quantity of received light of the peripheral-part light-receiving part 42 is operated in the signal processing circuit 50. The inside roughness of the slender pipe 2 is evaluated on the basis of the ratio. By this constitution, the inside roughness of the slender pipe 2 can be inspected with high accuracy and in a nondestructive manner without being affected by a change in the quantity of light incident on the slender pipe 2 and by the shift of the optical axis of the incident light.
