摘要： PROBLEM TO BE SOLVED: To provide steel for an automobile undercarriage component that excels in fatigue performance, not needing much cost in heat treatment and also excels in molding processability; and a process for manufacturing an automobile undercarriage component with the use of the steel. SOLUTION: The steel doped with Nb in combination with Mo is provided, wherein after bend forming such that the bend radius (R) at plate external surface becomes 2 to 5 times the thickness of the plate, the difference between the Vickers hardness at the center of the plate thickness and the maximum value of Vickers hardness within 0.5 mm from the surface ranges from 50 to 150 points. As the surface hardness is high with the hardness of the center part lowered, excellent fatigue performance and molding processability can be attained. Further, when annealing is carried out under conditions such that temper parameter λ defined by λ=T(20+log(t)) [wherein T is absolute temperature; t is time (h), and the temperature upper limit is 660°C] ranges from 14,000 to 19,000, a relaxation of internal stress can be achieved to thereby attain a further enhancement of fatigue performance.

摘要： PROBLEM TO BE SOLVED: To provide a spray pressure measuring apparatus for precisely measuring a jet state of spray without being damaged.SOLUTION: A second spring member 270 to be a plate spring of smaller spring constant than a first spring member 260 is provided in the center in the longitudinal direction of the first spring member 260 to be a plate spring for holding an optical fiber 250 in the state that it elastically deforms as a pressure transmission part 222 is displaced. Even in the environment where pressure is very weak and electromagnetic wave noise occurs, the weak pressure can be measured precisely. Even in situations where excessive pressure is given and the pressure transmission part 222 is considerably displaced, the second spring member 270 is elastically deformed and the first spring member 260 for holding the optical fiber 250 has a relatively small elastic deformation amount. It is prevented that a large ultimate tensile strength radically operates on the optical fiber 250 and that the optical fiber 250 is damaged by the breaking or the like.
