IPC: G01L11/02
Filed: 1997-12-24
Abstract: PROBLEM TO BE SOLVED: To make the constitution compact by measuring the pressure and a temperature of a plate having an electric fault by one unit in a wide range. SOLUTION: A light emitting diode 22 emits a pulse light and introduces the light into an optical fiber 23 via a half-mirror 24.

A light refractive index is changed corresponding to a pressure and a temperature at pressure element 25 and a temperature element 25 disposed at a predetermined interval in the fiber 23. And, an amount of the backward scattering light is changed as the index is changed. The scattering light is converted into an electric signal by the photodiode 27. The signal is then signal processed by a signal processor 28, thereby detecting pressure and temperature changes at positions where the elements 25, 26 disposed at predetermined positions in the fiber 23 are placed.

Abstract: PROBLEM TO BE SOLVED: To reduce sliding friction by forming recesses in the upper and lower portions of the outer periphery of a valve lifter used in a valve operating mechanism of the internal combustion engine, and using the recesses as upper and lower retaining portions for retaining a lubricating oil therein. SOLUTION: A valve lifter. 1 is formed by a cylinder 2 having its upper end closed by a top portion 3, and is biased upward by a spring 63. The valve lifter 1 is vertically reciprocated in response to rotation of a cam abutting on the top portion 3. In this valve lifter 1, a plurality of equally spaced recesses are formed in an outer periphery 21 of the cylinder 2, and specifically, at the upper and lower portions along the outer periphery 21. These recesses function as upper and lower retaining portions 4, 5. Each recess has such a depth that a lubricating oil flowing above and below the valve lifter 1 can be retained in the retaining portions 4, 5.  Thus, by enabling the lubricating oil to be retained in the upper and lower retaining portions 4, 5 of the valve lifter 1, friction between a guide hole and the upper and lower portions of the outer periphery 21 of the valve lifter 1 is reduced. As a result, smooth reciprocation of the valve lifter is assured.
