Title: Rolling bearing
Inventor: KIUCHI AKIHIRO
IPC: G01M13/04
Filed: 1998-10-28
Abstract: PROBLEM TO BE SOLVED: To eliminate the fear for production of a short longevity article even under such a harsh condition as a high load and high bearing by at least specifying specific depth of a bearing ring × size of a non-metal inclusion existing in detecting volume of a raceway surface. SOLUTION: Size of a non-metal inclusion existing in detecting volume of 2% Da depth × raceway surface of a bearing ring is made at least less than length 500 μm. The 2% Da depth shows depth from a surface of a rolling element to 2% of an average diameter of the rolling element. Steel of less than 9 ppm of an oxygen content of an impurity component and of less than 0.005 weight % of a sulfur content is used as a material of the bearing ring. Bearing longevity is extremely lowered in the case when a non-metal inclusion of more than length 500 μm exists in 2% Da depth in a longevity test, and depth that a value of shearing force to be generated by a rolling contact becomes maximum is less than 2% of the rolling element average diameter from the surface.  Consequently, none of unexpected short longevity articles is produced even under high load and high bearing harsh using conditions, and it is possible to guarantee stable longevity.

Title: Rib type optical waveguide
Inventor: TADA MASAMI
IPC: G02B6/122
Filed: 1989-11-29
Abstract: PURPOSE:To improve the utilization efficiency of the surfaces of a substrate by including a substrate and a core layer including a rib part formed on the substrate, and forming the core layer which has the rib part on >=2 surfaces of the substrate. CONSTITUTION:The two core layers 2 are formed on the top and reverse surfaces of the SiO2 glass substrate 1 by using UV-setting resin which has a larger refractive index than the substrate 1. Each core layer 2 has the rib part 2 which protrudes out at the center part of the substrate, and their rib parts 2a extend in the same direction and are formed integrally with their core layers 2. Each light beam LB is confined to the core layer 2 in the vertical direction because of the refractive index difference between the core layer 2 and air and the refractive index difference between the core layer 2 and substrate 1, and the effective refractive index of the part right below the rib part 2a becomes higher than that of its peripheral part in the lateral direction, so the light is confined to right below each rib part 2a. Consequently, the utilization efficiency of the substrate surfaces is improved.
