A new window display position determination section (102) displays the new window so as to be superimposed on the area having the low display priority.

Abstract: A keyword extraction section (108) extracts, from an electronic document (101), a plurality of character strings in accordance with information of a keyword management section (107). An action determination section (110) determines, with reference to an action definition management section (109), effect actions correlated with keywords which are corresponding to the extracted plurality of the character strings. An executing action instruction section (114) determines, from the extracted plurality of the character strings, character strings to the execute effect actions, and gives an instruction to an output control section (111). The output control section (111) controls, in accordance with the instruction given by the executing action instruction section (114), the effect actions to be executed by an output section (103).

Abstract: The water spray unit is used in conjunction with an ice product making machine having an upright freezing plate or freezing plates, on the surface or surfaces of which a plurality of guide ribs or projections are vertically formed at a preset transverse distance from one another. The spray unit has a main body provided above the freezing plate or freezing plates and presenting a large number of spray apertures, and a plurality of water spray guide plates disposed between the guide ribs or projections and presenting a pair of upright side flanges. The spray water is discharged from the spray apertures and caused to descend along the freezing plate or freezing plates by way of the water spray guide plates, the upright side flanges and the guide ribs or projections as a turbulence-free uniform stream.
