Title: Led lighting device and lens
Inventor: ONO YUKI
IPC: F21S2/00
Filed: 2010-08-25
Abstract: PROBLEM TO BE SOLVED: To provide an LED lighting device and a lens capable of being manufactured at low cost, yet with superb light distribution characteristics.SOLUTION: If a plurality of LEDs include at least one each of red LEDs, green LEDs and blue LEDs, light of three colors of red, green, and blue emitted from each LED goes on to mix colors as it progresses inside the lens 1 made of diffusing resin, and further becomes converged light by being refracted at a convex-shape emitting face 5 to have white-color light with color unevenness restrained emitted outside the lens 1. Since the lens is formed of the diffusing resin, the color unevenness can be effectively alleviated irrespective of arrangement of an LED light source, and that, light distribution characteristics can be arbitrarily set.

Title: Method of reducing contact force variation in pantograph, and pantograph
Inventor: IKEDA MITSURU
IPC: B60L5/26
Filed: 2010-08-26
Abstract: PROBLEM TO BE SOLVED: To provide a method of reducing contact force of a pantograph performing active control using a signal not containing a high-frequency component, relatively.SOLUTION: The pantograph 1 includes an actuator 50 dynamically controlling contact force in a vertical direction between an overhead wire T and a contact strip 10, and further includes a displacement meter 55 measuring displacement of a framework 20. The actuator 50 is controlled by impedance control. The impedance control performs the control by adding a virtual spring element and an attenuation element by the actuator 50 to reduce contact force variation of the pantograph. The necessary minimum signal in the control is only the displacement of the framework 20. Because the displacement is less likely to include a large high-frequency component, a gain can be stately adjusted even in a high-frequency domain, and the contact force variation in a frequency range of about 1 to 2 Hz can be reduced.
