Abstract:
In three-dimensional data generation unit 120, data edition unit 122, generates a spreadsheet data that includes information relating to a plurality of node points on a continuous arrangement route of target components by interactive process with a user, and stores the data in storage unit 130. Three-dimensional data conversion unit 123, on the basis of spreadsheet data, arranges the node points in a three-dimensional space, connects node points having a predetermined relationship using line segments, and imparts cross-sectional shapes to the connected line segments, to carry out thereby conversion into target component arrangement three-dimensional data. Three-dimensional data management unit 124 stores the obtained target component arrangement three-dimensional data in storage unit 130, in a format readable by three-dimensional CAD or three-dimensional review system, and outputs the data in response to an output instruction from interface unit 110.
Abstract:
An isolated power conversion apparatus has an isolation transformer, a series circuit including a load and an inductor connected in series with each other, the series circuit being disposed on a secondary side of the isolation transformer, and one or a plurality of switching means disposed between the series circuit and the secondary side of the isolation transformer, the switching means being bidirectional. This apparatus sends out power from a DC power supply of a primary side of the isolation transformer toward the load as DC power or AC power of an arbitrary polarity, or regenerates and supplies the DC power or AC power from the load to the DC power supply.

Abstract:
A projection exposure method and apparatus are disclosed, which can perform a focusing operation with respect to a partly omitted shot exposed at a peripheral portion of a photosensitive substrate such as a wafer. In the projection exposure method and apparatus, when a prohibition band having a predetermined width is set from the edge of the substrate, and exposure is to be performed with respect to a shot area having a portion located only within the prohibition band and the remaining portion located outside the edge of the substrate, a focus detection point is shifted to the boundary line of the prohibition band on the substrate, and a focusing operation is performed. Thereafter, the focus detection point is moved to an original target shot exposure position to perform exposure.
