    • The cross-sectional shape data of a three-dimensional model is divided according to work small areas obtained by dividing a work entire area where optical shaping work is performed into a plurality of areas, and work small area data which is cross-sectional shape data corresponding to said work small areas is generated. Also, the work small area data is enlarged with offset width based on the contracting ratio of a light hardening resin, and areas, which are wider than the work small areas on the surface of the light hardening resin by the offset width, are subjected to one-shot exposure based on the enlarged work small area data to form a hardening layer for each of the work small areas. The present invention can be applied to, for example, an optical shaping apparatus.

    • A deaeration method for eliminating dissolved gases from a liquid product, which method involves low initial cost and running cost, compact equipment, and simple arrangement to accomplish the deaeration. For the method to eliminate dissolved gases from a liquid product, a deaeration module which is divided by a gas-pervious membrane into a liquid phase side and a vapor phase side is used. A deaeration-use gas composed of one or more kinds of inactive gases is previously dissolved in a liquid product to be deaerated, whereby a deaeration-target liquid is prepared. The deaeration-target liquid is distributed on the liquid phase side, in which distribution process the deaeration-use gas moves to the vapor phase side via the gas-pervious membrane, while the dissolved gases move to the vapor phase side along with the movement of the deaeration-use gas. This movement of the gases is carried out during passage through the deaeration module under ambient pressure.
    • 用于消除液体产物中溶解气体的脱气方法,该方法涉及低的初始成本和运行成本,紧凑的设备以及完成脱气的简单布置。 为了从液体产物中除去溶解气体的方法,使用由气体透过膜分成液相侧和气相侧的脱气组件。 预先将由一种或多种惰性气体组成的除气用气体溶解在要脱气的液体产物中,由此制备脱气目标液体。 脱气靶液体分布在液相侧,其中脱气用气体通过气体透过膜移动到气相侧,其中分解过程中溶解的气体随着气相侧移动到气相侧 脱气用气体。 气体的这种移动在环境压力下通过脱气模块时进行。
