4 example description
This example shows a sequence valve database file SXFLIB.DBF in the design of the hydraulic system software package established by Visual Foxpro3.0 environment. The data structure is shown in the following table.
| Name | Type | Diameter | Pressure | Flux | Scale |
| Sequence valve | XF * 10D3-P- * | 10.0 | 20.0 | 40.0 | 0.5 |
| Sequence valve | 2X-F * 10D3-AB/BA- * | 10.0 | 20.0 | 40.0 | 1.0 |
| One-way sequence valve | XA-F * 10D3-B- * | 10.0 | 20.0 | 40.0 | 0.7 |
| One-way sequence valve | XA-F * 10D3-B(A)- * | 10.0 | 20.0 | 40.0 | 0.5 |
Develop an ASI application to achieve the required functionality:
(1) Compile the ins-rowvalue command to insert the data and name on the AutoCAD drawing into the record of the database.
(2) Prepare the get-rowvalue command to read the data from the selected row of the database, display it in the software dialog box, and draw the graph according to the ratio provided by the data.
(3) Compile the fetch-dallue command to read all the records from the database and display them in the list box of the dialog box for the user to call and insert into the graph.
Because AutoCAD can access the database through ASI/ASE and DBMS, the design ideas of many application projects are greatly expanded, which saves the designer's working time, improves the work efficiency, reduces the input cost, and is beneficial to the realization of the integrated system.

Axicon (conical lens) is a conical prism used to create non diffractive Bessel beams
Axicon lenses are conical lenses which, when followed by a conventional lens, can focus laser light to a ring shape. Using an axicon together with a spherical lens will produce an annular focus for hole drilling applications. We offer Plano-Convex , Plano-Concave, Double Convex Axicons.
