Abstract: A data processing apparatus has an input unit for entering operator data and commands, and a display unit for displaying a work area for data processing. The display unit opens a job menu window for displaying types of selectable jobs by icons at a center of a display screen when the operator needs to select a new job.

Abstract: A document creating apparatus for creating and editing a document in which a plurality of different types of descriptive element data, such as text data, graph data, pattern data, image data and other data, coexist. Plural types of edit sections are provided in correspondence with the types of data to be handled. Various types of data are edited under coordination by selecting edit sections corresponding to the types of data, respectively, while maintaining the editing function of the editing section once selected and activated so that the editing section can be selected again without losing its editing function.

Abstract: The document edition unit includes region set apparatus for setting a size of the region to a size corresponding to the print output, region attribute set apparatus for setting attribute information, region information hold apparatus, and text re-determination apparatus. The text data edition unit includes text input control apparatus. The region information hold apparatus manages the size and position of the region set by the region set apparatus in the size and at the position corresponding to those of at the time of print output, and manages the attributes set by the region attribute set apparatus so as to correspond to them. The text input control apparatus controls the arrangement to the character string at the time of text input by referring to the region information whose position on the page is fixed. When the user makes the operation which changes the input region of the text, the text re-determination apparatus re-determines the arrangement of the texts inside the page in accordance with the region.

Abstract: A document producing apparatus comprises an input unit for inputting descriptive contents such as characters or figures which contstruct a document and a format which defines a sheet size of a paper sheet used, a sheet direction of portrait or landscape in which the sheet is to be used, and a layout of the descriptive contents in each page, a storage unit for storing therein the descriptive contents and the format inputted from the input unit, a display unit for selectively displaying the contents stored in the storage unit, and an in-document layout editing unit for displaying on the display unit a layout of a plurality of pages forming the document so that page information of the respective pages are partitioned in due order from a leading page and for every predetermined number of pages and are arranged in one display image, the page information including at least the sheet size and the sheet direction stored in the storage unit.

Abstract: A cable detector has a plurality of rotatably series connected hooks having an opening mouth for accepting a cable on sea bottom with an equal angular intervals, a contact pressure sensing means for indicating that a cable is engaged with one of said hooks by measuring contact pressure on one of the hooks, and an electrical switch which is actuated by said contact pressure sensing means to provide an electrical signal when a cable is detected.

Abstract: A laser butt welding apparatus including a pair of clamp elements at least one of which is movable reciprocally along the steel strip-feed line direction and which are adapted to clamp the edge portions of preceding and trailing steel strips, a shear which is advanceable and retractable between the pair of the clamp elements in a perpendicular direction to the line and cuts the edge portions of the preceding and trailing steel strips, structure for butting the cut faces of the preceding and trailing steel strips while being clamped by means of the clamp elements, and a laser torch adapted to condense a laser beam from a laser oscillator on an off-line at a weld zone and movable in a width direction of the steel strips to be welded together.
