Inventor: SUDO SHUJI
IPC: F16C33/78
Filed: 1995-12-14
Abstract: PROBLEM TO BE SOLVED: To prevent leakage of a lubricant to the outside of a bearing when the rotation part of a precise apparatus is rotated at a high speed. SOLUTION: The mounting part 2a of a shield plate 2 formed in an arcuate shape in cross section and the insertion part 3a of an outer ring 3 to which the mounting part 2a is fixed are covered in approximate 50μm in thickness with a film P, such as fluorine resin, having water repellence and penetration resistance.

Filed: 1993-12-28
Abstract: PURPOSE:To hold antifreeze solution concentration constant and to simultaneously improve a heat recovery efficiency by partly heating the solution to be scattered in a tower and discharging evaporative vapor to the atmosphere by tower exhausting means. CONSTITUTION:A heating tower 10 has a casing 12 on a cylindrical vessel of a square or cylindrical section. A fan 14 is mounted as tower exhausting means at a top, and an atmosphere intake port 16 is opened at a position near a side lower part of the casing 12.

Title: Color sensor for measuring polyol
Inventor: YAMAMOTO HIROMASA
IPC: G01N31/22
Filed: 1995-12-25
Abstract: PROBLEM TO BE SOLVED: To measure the concentration of polyol conveniently by using a sensor containing a mixture of an oxidation/reduction indicator and a derivative of ferrocenyl boric acid shown by formula [I].

Polyol can be measured effectively because it forms a complex with the boric acid group of a derivative of ferrocenyl boric acid to increase the reducing power of ferrocene ring thus reducing an oxidation/reduction indicator. The oxidation/reduction indicator preferably includes an indophenol derivative shown by formula [II], where X<1> , X<2> and X<3> represent hydrogen, chlorine or bromine independently.
