Title: Bearing system
Inventor: AMANO YASUSHI
IPC: F16C13/02
Filed: 2007-02-08
Abstract: <P>PROBLEM TO BE SOLVED: To provide a bearing system wherein lubrication performance is maintained over a long period.  <P>SOLUTION: Lubricating oil for a self-aligning roller bearing 12 is stored in a housing. The inside diameter ϕS of seal lips 13a, 13b is made smaller than ϕP of PCD of the self-aligning roller bearing 12. As a result, the lubricating oil stored in the housing leaks outside between the seal lips 13a, 13b and a roller 4. Thus, the level of the lubricating oil remains unchanged, and the self-aligning roller bearing 12 is lubricated in the same conditions. The inside of the housing is pressurized by gas supplied from a lubricating-oil supply device. Since the pressure in the inside across the seal lips 13a, 13b is higher than the pressure outside, the entry of the extraneous matters from outside is efficiently inhibited.  <P>COPYRIGHT: (C)2008,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To provide a photomask capable of precisely working a light-shielding pattern and suppressing the variation of resist line width due to flare, and to provide a manufacturing method for the photomask.  <P>SOLUTION: In the photomask, a stripe part S1 of the light-shielding pattern, having a small window width is affected less by flare light, so that the hollow size of side surface 11A of a protrusion part 11 of a transparent substrate 1 is enlarged, and thereby the canceling due to interference of oblique incident light is reduced. Meanwhile, a stripe part S3 of the light-shielding pattern having a large window width is largely affected by flare light, side surface 13A of a protrusion part 13 has no hollow; and thereby, the canceling due to interference of oblique incident light is increased. Accordingly, without having to change the line width of the stripe part S1 of each light-shielding pattern, energy quantity contributing resist resolution in each light-shielding pattern can be balanced.  <P>COPYRIGHT: (C)2008,JPO&INPIT
