Title: Mechanical seal having seizure preventing function
Inventor: HANADA TATSUMICHI
IPC: F04B39/00
Filed: 1993-11-29
Abstract: PURPOSE:To prevent the abrasion of a seal by constituting a fixed ring from a metal holder and a nonmetallic ring which is inserted into the metal holder and have a seal surface and a rotary ring, forming the sectional surface in the circumferential direction intentionally into a noncircular shape before the fitting of the metal holder or the nonmetallic ring, and finishing the seal surface of the nonmetallic ring in a plane at a certain temperature after fitting. CONSTITUTION:A fixed ring 7 is constituted of a metal holder 7a and a nonmetallic ring 7b. In the manufacture of the nonmetallic ring 7b, the sectional surface in the circumferential direction is formed to a noncircular shape, and formed to a three-point contact form for the outer periphery. When the nonmetallic ring 7b is fitted with the metal holder 7a, undulation is generated on the surface of a seal surface A due to the nonuniform interference. The surface is plane-finished at the temperature in the ordinary operation of a mechanical seal, and a fixed ring 7 is formed. Accordingly, at the temperature other than the finishing temperature, the fitting interference changes because of the thermal expansion, and the material and interference are selected so that the flatness changes. Though, when undulation is generated on the seal surface, leak increases temporarily, the initial working condition is set so that the leak quantity is set within an allowable value.

IPC: G02F1/1335
Filed: 1992-12-02
Abstract: PURPOSE:To provide the process for production of the color filter having small film thickness distributions of transparent colored patterns of red, green and blue and good spectral characteristics. CONSTITUTION:This process consists in applying a color resist on a glass substrate 2 arranged within a chamber 10 of a spin coater 1, rotating this substrate around the axis approximately perpendicular to the coating film surface to approximately uniformalize the coating film thickness, then drying the coating film and forming the film of the color resist on the substrate. The film thickness of the color resist is set at a prescribed value by adjusting e/Ex100 [relative humidity: %] in the chamber 10 when the amt. of the solvent included in the air in the chamber 10 is defined as (e) and the amt. of the satd. solvent of the air at the temp. in the chamber 10 as E. The film thickness adjustment is executed by changing the relative humidity in the chamber 10 according to this method and, therefore, the set rotating speed of the substrate 2 is unified approximately to a specified speed and the influence of wind cutting is approximately equalized according thereto. The color resist films by respective colors having the stable film thickness distributions are thus formed on the substrate 2.
