Abstract: A program causes an information processing apparatus to activate a second application that provides an extended function to a first application, superimpose and display a menu of the second application on the first application in response to a predetermined operation at a predetermined position on a screen where the first application is displayed and the second application is not displayed, and execute processing corresponding to the extended function selected from the menu.

Abstract: To provide an extension function that permits more intuitive operations without interfering with the behavior of an external application. There is provided an information processing apparatus that includes a controller configured to control functional extension of an external application. The controller causes an extended menu icon whose display position is adjustable to be superimposed and displayed on a display window of the external application, and controls a display position of an extended menu according to the display position of the extended menu icon. The controller causes an extension function icon to be superimposed and displayed on the display window with a display position of the extension function icon being adjustable, the extension function icon being associated with an extension function selected on the extended menu, and controls a display position of a sub-icon accompanying the extension function icon, according to the display position of the extension function icon.

Abstract: Provided is a user interface easy to customize. An information processing apparatus is an information processing apparatus including a control unit. The control unit included in this information processing apparatus displays an operation screen on a display surface of a display unit in a case where an operation of editing a plurality of operation elements placed on the operation screen is performed to place each operation element on an edit screen. In addition, while displaying the operation screen on the display surface of the display unit, this control unit displays a part of an image indicating a placement location on the edit screen of each operation element on the display surface.

Abstract: A fluid supply apparatus includes a main passage through which fluid flows, a parallel passage section, and a pressure loss adjusting mechanism. The parallel passage section includes a plurality of passages connected in parallel to the main passage. The parallel passage section includes a selector valve, which changes the number of passages through which fluid passes among the plurality of passages. The pressure loss adjusting mechanism suppresses change in the pressure loss at the parallel passage section associated with change in an operating state of the selector valve.
