Filed: 1998-11-17
Abstract: PURPOSE: An indoor air circulator of an industrial high frequency heater is provided to enhance the drying efficiency of a material to be heated by radiating high frequency to the material as well as to circulate heat from the material into a cavity forcibly. CONSTITUTION: A door is closed after a trolley(400) where materials to be heated are accumulated is introduced into a cavity(100). Then, electric power is fed to an electric device unit(200) to oscillate high frequency from a magnetron of the unit(200). The high frequency passes a dispersion plate(250) to be radiated to the materials to be heated. At the same time, external air is introduced into the inside from a cooling fan of the electric device unit via the magnetron, a power source unit and an air path of side panels(110,120). The high frequency is collided with the materials so that friction heat is generated and water is evaporated from the materials to dry the materials. Then, the excessive vapor is discharged to outside to maintain the normal degree. Also, internal air is circulated by wind caused by a fan(112).

Title: Disc driving device having sound blocking wall
Inventor: PARK GEON SUN
IPC: G11B33/14
Filed: 1998-12-04
Abstract: PURPOSE: A disc driving device having a sound blocking wall is provided not to deliver a noise generated inside the disc driving device to an outside. CONSTITUTION: A disc driving device is equipped a sound blocking wall(2), a tray(10) and a mechanism base(20). The sound blocking wall(2) blocks an airflow generated around a disc(1) according to the rotation of the disc(1) by covering a upside and a side of the disc(1). Thereby a noise generated by the airflow around the disc(1) is not delivered to an outside. The sound blocking wall(2) is formed by a metal or a plastic having a large hardness because an elastic coefficient is larger, a blocking effect of noise is larger. The sound blocking wall(2) supports a clamper(4). The clamper(4) clamps the disc(1) by a clamping force to magnetically stick with a magnet installed in a spindle motor. The sound blocking wall combined in a sidewall of the mechanism base(20) minimizes the delivery of noise generated around the disc(1) to the outside by minimizing a gap between the tray(10) and the mechanism base(20).
