20140306249 | LIGHTING APPARATUS - This lighting apparatus includes three or more LEDs arranged in a row. Each of the LEDs emits light of a color different from that of an LED adjacent to itself, and the LEDs include an LED having a relatively wide light distribution angle and others of the three or more LEDs each having a relatively narrow light distribution angle. The one LED is arranged in an inner portion in the row of the other LEDs. In this configuration, light emitted from the one LED is mixed well with lights emitted from the respective other LEDs adjacent to the one LED, and thus, color unevenness of illuminating light can be reduced. | 10-16-2014 |
20140307454 | LIGHTING SYSTEM - A lighting system includes a lighting apparatus provided along one side of an aisle and a specular reflection plate provided along the other side of the aisle to reflect the light emitted from the lighting apparatus toward a region where the lighting apparatus is provided. According to the above configuration, the lighting apparatus can illuminate the region where the lighting apparatus is provided. Therefore, it is possible to effectively illuminate a cabin of an aircraft with less lighting apparatuses as compared to conventional lighting apparatuses which are provided along both sides of the aisle. Moreover, since the number of the lighting apparatuses can be reduced, it is possible to improve fuel efficiency of the aircraft by reducing the total weight of the aircraft. | 10-16-2014 |

20100222170 | DOUBLE-SIDED DRIVING SILENT CHAIN AND DOUBLE-SIDED DRIVING SILENT CHAIN TRANSMISSION USING THE SAME - A silent chain using double-sided driving link plates having symmetrical upper and lower teeth has a problem that it is unable to assure a required risky sectional area of the plates because a width between upper and lower crotches is narrow. The invention provides a silent chain using double-sided driving link plates whose required risky sectional area is maintained by using link plate whose back side is undercut and whose upper and lower parts are unsymmetrical even though its front side has a shape of a normal link plate. A distance from a line connecting centers of pin holes to a bottom of an upper-side crotch is equal to or more than ½ of a diameter of the pin hole to assure the risky sectional area. Teeth of the back side are cut away to form a flat surface to assure a contact area with a shoe and others. | 09-02-2010 |
20100307128 | LINK CHAIN - A bush is pressed into a link plate in a turning link rank that turns relatively with a pin. The bush is molded into a seamless cylindrical shape by cold-forging and is coated with a metal carbide layer formed by cementation of chrome, vanadium and others and having Vickers hardness of 1300 Hv or more similarly to the pin. After that, the bush is treated by a quenching, tempering or isothermal transformation process. Thereby, wear resistance of the pins and the link plates of a silent (link) chain is improved, productivity is improved and the cost is cut. | 12-09-2010 |
