When the selection input of the cylinder inner diameter is completed, the process proceeds to a stroke selection step of S26 in FIG. When S26 is executed, the screen of the display means 4 is displayed as shown in FIG.
The screen changes to the stroke selection screen shown in (1). On this screen, basic configuration diagrams 16A and 16B of the selected A11B type cylinder unit, selected type name [A11B to type] 17, selected cylinder inner diameter value 21, standard stroke specification selection table 22, and intermediate stroke value entry column 23 and a long stroke value entry field 24 are displayed, and the selected type name [A11B to type] 17 and the character [stroke] 19c in the basic configuration diagram 16A are highlighted. The operator operates the 25 mm to 200 mm displayed in the specification selection table 22 for the standard stroke.
The desired stroke value is selected from the set values up to mm, and the cursor is moved to the desired stroke value to execute. Of course, 25mm ~ 20
When an intermediate value of the set value up to 0 mm is required, or when 200 m
When a stroke exceeding m is required, the cursor is moved to the appropriate entry column 23 or 24 depending on whether the stroke is an intermediate stroke or a long stroke, and a stroke value is input and executed. At this time, since the maximum stroke value that can be written is also written on the right side of the long stroke writing column 24, it is referred to.

When the input of the selection of the stroke value is completed, the process proceeds to a shaft pitch selection step of S27 in FIG. The screen of the display means 4 changes to a shaft pitch selection screen shown in FIG. In this screen, the selected A11

Match or enter the corresponding number and execute.

As described above, the type A in S14 shown in FIG.
The selection program ends, and then a model number confirmation step of S19 is executed. This means that the model number of the type A direct acting cylinder unit which is intended by the model number creation program stored in the storage means 2 is created based on the specification of the specific part selected and input by the operator in S23 to S28 of FIG. Then, it is displayed on the screen of the display means 4. This model number confirmation step S19 is not essential to the present invention and can be omitted.
When incorporating 19, the model number displayed on the screen must be changed, for example, by moving the cursor to the desired item position and inputting characters in accordance with the procedure for changing the model number displayed on the model number display screen. It is desirable to configure so that Of course, when the model number is changed, the specification of the corresponding part is automatically changed from the selected and input one to the changed one.

When the user finally confirms the model number and performs an operation of acknowledgment, a load capacity confirmation step in S20 of FIG. 4 is executed, and whether or not [confirmation of load capacity] is displayed on the screen of the display means 4 is determined. When selecting and inputting and confirming the load capacity, the load capacity of the cylinder unit of the determined model number is arithmetically processed and displayed on the screen of the display means 4.
