Title:
POWER GENERATION METHOD AND OBJECT POSITION DISPLAY DEVICE USING THE SAME
Document Type and Number:
Japanese Patent JP2015089309
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a power generation method for surely generating induction current in a coil by mainly using expansion/contraction force and vibration of external energy, and a device which lights up using the induction current.SOLUTION: A device comprises: a move part formed by connecting a second magnet 18 to the lower part of a pipe 14 having a first magnet 20 for generating induction current in a coil 12 and connecting a tension spring 21 and wire 5 to the upper part of the pipe 14; and a fixed part formed by attaching a third magnet 19 for giving suction force to the second magnet 18 to the lower part of a pipe 4 including the coil 12. The device makes the second magnet 18 be close to the third magnet 19 and moves the first magnet 20 to acquire current flowing in the coil 12; and moves the first magnet 20 at the moment when contractive force of the tension spring 21 exceeds suction force of the third magnet 19 and second magnet 18, to acquire current flowing in the coil. The device and another device which lights up using the device are formed to display a position of an object to which the other device is attached.
