    摘要： There are provided a hydrodynamic bearing assembly and a spindle motor including the same. The hydrodynamic bearing assembly includes: a sleeve including a shaft hole to have a shaft rotatably installed therein; and a cover member covering the shaft hole at a lower portion of the shaft hole in an axial direction, wherein an inner surface of the sleeve is provided with depression parts depressed in an outer diameter direction between upper and lower portions of the sleeve and portions in which radial bearings are formed, such that the portions in which the radial bearings are formed are provided with bearing closure adhesion parts allowing the portions in which the radial bearings are formed to be closer to the shaft than portions other than the portions in which the radial bearings are formed.

    摘要： The present invention relates to a 3D printer and a printing system. The present invention may include: a storage unit formed in a hexahedral shape and having an open top and a bottom surface formed of a film layer comprising an upper film layer, the storage unit storing a photocurable material therein; a light source unit comprising at least one light emitting diode, the light source unit being disposed below the storage unit and radiating light toward the photocurable material; and a switching unit comprising an LCD panel disposed between the light source unit and the storage unit, the switching unit opening and closing each pixel included in the LCD panel to selectively pass light emitted from the light source unit toward the photocurable material. Accordingly, light emitted from below the storage unit can be emitted toward the photocurable material without being distorted.

    摘要： There are provided a cochlea implant system including an in the ear (ITE) speech processor and an implanted part. In the cochlea implant system, the speech processor and the implanted part transfer and receive a signal by infrared data communication. The implanted part includes a receiving unit for receiving an infrared signal from the speech processor to demodulate the infrared signal, a stimulation circuit unit for converting the demodulated signal into a stimulation signal, an electrode array inserted into the cochlea to stimulate the auditory neurons by the stimulation signal, and a coil for receiving power from the outside through the RF power transmission. The implanted part can receive power from the outside through the coil to be charged.
