20150231974 | Electric Construction Machine - Provided is an electric construction machine adapted to prevent an electric current, after flowing in via a junction at which power transmission systems join together, from flowing into at least one connector to which an external power supply is not connected. | 08-20-2015 |
20150295520 | POWER GENERATOR - A power generator including: a vibration system configured to be attached to a vibrating member; and a power generating element attached to the vibration system. The vibration system is a multiple-degree-of-freedom vibration system that includes a first vibration system having a first mass member elastically supported by a first spring member, and a second vibration system having a second mass member elastically connected to the first mass member by a second spring member. The power generating element is arranged between the first and second mass members, and vibration applied from the vibrating member causes relative displacement of the first and second mass members so that vibration energy of the vibrating member is input to the power generating element. A natural frequency of the first vibration system is different from that of the second vibration system. | 10-15-2015 |

20160043663 | VIBRATION POWER GENERATOR, VIBRATION MONITORING DEVICE, AND VIBRATION MONITORING SYSTEM - A vibration power generator includes a vibration system attached to a vibrating member. The vibration system includes a first vibration subsystem, and a second vibration subsystem attached to the first vibration subsystem. The first vibration subsystem includes an elastic member attached to the vibrating member, and a first mass member attached to the elastic member. The second vibration subsystem includes a plate spring integral with a piezoelectric element, and a second mass member attached to the plate spring. The first vibration subsystem has a resonant frequency that is substantially equal to a resonant frequency of the second vibration subsystem. | 02-11-2016 |
