| 20090318320 | Lubricating Oil Composition - The present invention involves the addition of an aspartic acid derivative and a fatty acid ester of a polyhydric alcohol to a base oil of, e.g., mineral oil or synthetic oil type. By including these additives, a lubricating oil composition having excellent rust-preventing properties, reduced friction coefficient and excellent energy-saving properties and so being suitable for industrial lubricating oils can be obtained. Also, by further adding an epoxy compound and by adding also a fatty acid amine, it is possible to obtain a lubricating oil composition even more endowed with rust-preventing properties and energy-saving properties. | 12-24-2009 |
| 20100073926 | Flame Detector - A flame detector is provided. A circuit board is disposed in a housing. A first light source emits first light. A light guide member comprised of translucent material guides the first light from the first light source to a light emission portion of the light guide member. A first light receiving element detects second light having a predetermined wavelength unique to the flames. A second light source emits third light to a translucent cover which is disposed between an opening of the housing and the first light receiving element. A second light receiving element detects the third light passed through the translucent cover to test the translucency. The first light source, the second light source and the second light receiving element are mounted on the circuit board. The light emission portion is formed into a substantially annular shape which encloses the first light receiving element at a front side of the housing to limit a field of view of the first light receiving element to a predetermined range. And the light guide member has a light entrance portion and a light exit portion for the third light to form a light path from the second light source to the second light receiving element through the translucent cover and the light guide member. | 03-25-2010 |
