Abstract: Provided is a device for massaging eyes comprising a mask received in a compartment and comprising annular left and right guards surrounding rear portions of left and right eye portions respectively, and left and right diaphragms in the eye portions respectively; a pneumatic-powered cylinder assembly for converting rotating motion into reciprocating motion; and a plastic tube interconnected the mask and the cylinder assembly. In operation, air having positive or negative pressure is built in the cylinder alternately prior to communicating to the eyes for massaging. There are provided protrusions around a rear portion of each guard. In another embodiment, there are provided left and right soft spacers attached to rear surfaces of the diaphragms respectively.

Abstract: A mask applied in the process of miniaturizing a structural device is disclosed. The mask comprises a plurality of layout pattern areas for defining layers of the structural device, wherein at least one layout pattern area is arranged on the mask in a regular rule. A method for exposure is also disclosed. First, a mask comprising a plurality of layout pattern areas for defining layers of the structural device is provided, wherein at least one layout pattern area is arranged on the mask in a regular rule. Then one of the layout pattern areas is selected and the other layout pattern areas are covered. Finally, the mask is aligned with a substrate and the exposure is performed to transfer the pattern of the selected layout pattern area to the substrate.
