An exterior inspection device configured to inspect whether or not a molded product in a predetermined shape has defectiveness based on an image of the molded product, the inspection device including: a first foreign matter determiner configured to determine whether or not, in an obtained image of the molded product, a first inspection region located inside an outline of an assumed normal molded product P includes foreign matter; and a second foreign matter determiner configured to determine whether or not, in the obtained image of the molded product, a second inspection region located outside the outline of the assumed normal molded product includes foreign matter.

Inspection device and molded-product processing system

A molded product processing system is configured to apply a post process to a molded product molded by a compression-molding machine. The system includes modules each including a conveying mechanism configured to convey a plurality of molded products P kept aligned, and a processing mechanism confronting a travel route of the molded products conveyed by the conveying mechanism and configured to apply a predetermined post process to each of the conveyed molded products, in which upstream one of the modules and downstream one of the modules are connected to allow the molded products having gone through certain processing at the upstream one of the modules to be delivered to the downstream one of the modules and be subjected to a different predetermined processing at one of the modules.

Molded product processing system

Hard metal particles having hardness which is lower than the hardness of a nitrided outermost layer of a spring and in the range of Hv 500 to 800 and a diameter of 500 to 900 &mgr;m are protected against the nitrided surface of the spring at a velocity of 40 to 90 m/sec to prevent generation of a microcrack in the surface layer and provide a compression residual stress comparatively deep inside the spring. Against the resultant spring surface, a number of fine metal particles having a mean diameter of all particles of 80 &mgr;m or less, a mean diameter of each particle in the range between 10 &mgr;m inclusive and less than 100 &mgr;m, a spherical or near spherical shape with no square portions, a specific gravity of 7.0 to 9.0, and hardness which falls in the range between Hv 600 and Hv 1100 inclusive and is equal to or less than the hardness of the outermost surface layer of the spring after nitriding, at a velocity of 50 to 190 m/sec., while controlling temperature to be low enough to cause work hardening but not to cause softening due to recovery/recrystallization, to provide a high compression residual stress in a near surface layer without generation of microcracks in the surface layer and thus obtain a valve spring and the like excellent in fatigue strength.

Spring with excellent fatigue endurance property and surface treatment method for producing the spring

A ratchet 3 is secured to a rotatable base plate structure 2 of an arm rest device 20. A Y-shaped pawl member 7 is pivotally attached to a stationary plate 6 by a pivot shaft 14 and a toggle spring 8. The stationary plate 6 includes a proximal end portion fitted over a fixation shaft 5. A tooth pawl 13 formed in one end portion of the Y-shaped pawl member 7 is engaged with a row of serrated teeth 10 of the ratchet 3 within a predetermined extent (from point A to point B) of pivotal movement of the base plate structure 2, by reason of urging load P from the toggle spring 8. Thus, the arm rest body 18 is fixed at a predetermined position. An engagement groove 32A in the Y-shaped lever 32 prevents the arm rest body in an accommodated position from being pivoted in a forward direction.
