Abstract: Disclosed is a vibration apparatus for generating a spheroid wavelength by eccentrically rotating a rotation shaft using an eccentric weight.

Abstract: The present invention relates to a medical apparatus for spinal therapy, which is a bed-type apparatus equipped with a treatment head and performs message and acupressure while moving along the length of the spine, and more particularly to a fixing structure of a treatment head in the medical apparatus, which wears out slowly and allows the treatment head to move in a vertical direction. The medical apparatus for spinal therapy having the fixing structure of a treatment head is advantageous over known apparatuses in that it can give various types of stimulation to human body parts and incurs lower maintenance expenses.

Abstract: Disclosed is a device for shielding an electromagnetic wave. The electromagnetic wave shield device comprises a relay having a contact selectively connected to a first terminal or a second terminal of a power receptacle; a controller controlling the connection between the contact of the relay and the first terminal or the connection between the contact of the relay and the second terminal, comparing the first voltage value generated by the connection between the contact of the relay and the first terminal with the second voltage generated by the connection between the contact of the relay and the second terminal, and controlling the relay so that the contact of the relay is connected to the terminal having the lower voltage value; and an electromagnetic wave shielding unit for providing the electromagnetic wave generated by an electric and electronic device to the terminal having the lower voltage value.
