A graphic processing apparatus for generating, displaying or printing characters and graphic data. A successive column access is used in which a row address is designated for access to a memory and data in different column addresses within the designated same row address are successively accessed and buffer means for buffering a series of data between an access by a processor and an access to a memory is provided. A program and image information for display are stored in a main memory. A frame b...

A graphic computing apparatus has a shape divider which generates a subpolygon mesh by dividing the unit shape of the surface of an object present in a three-dimensional space into a plurality of subpolygons arranged two-dimensionally and having an arbitrary size, a vertex processor which computes parameters required for drawing in units of pixels with respect to subpolygons for each vertex of the subpolygon mesh generated by the shape divider, a rendering processor for computing drawing data in...

A system and components are provided for assembling at least two boards into a composite. A pair of bridging members may each be secured to an associated board and have a central surface portion spaced apart from the surface of the associated board. An elongate bar is provided having a length, width and thickness effective to permit the bar to be inserted between the central surface portion and board surface of two adjacent bridging members so that the bar tends to hold the two boards in a prede...

A graphic processing system has a processor for managing a display area and a character font area both include within an are disposed in the address space. From coded information indicative of a character transferred through a data bus of the system, the processor generates an address at which a character font pattern of the corresponding character has been stored and transfers that character font pattern to a predetermined position on the display area. The graphic processing system realizes hig...

A method to easily draw a graphic having many control points using graphical icons. The control points necessary for defining a graphic are displayed on an icon display screen together with a graphical icon. Information on the operation sequence for the control points is also displayed on the screen by blinking the control points. The state of the control points specified by the user is displayed in the form of animation by a control-point moving and displaying apparatus and is displayed on a gr...

An educational graphic display apparatus which, by use of electronic techniques displays graphically a function of a variable. The only programming necessary is the selection of the function type and the setting of coefficient values and a sequence of functions with different coefficient values can be displayed without the necessity of complex reprogramming for each new function. The apparatus of this invention utilizes at least one integrator responsive to a reset control signal and a forward/r...

The present invention relates to a graphic arts toy wherein a flexible string may be selectively attached at a wide variety of points around an exposed display surface to portray any desired pictorial representation and wherein the string may be quickly and easily stripped from the display surface after use and stored for futher use.

Photo Graphic-Plane is a system that will facilitate the photographic process. It is a pneumatic device designed to support books and volumes at a level plane with minimum curvature of the surface while being microfilmed or photo-copied. This objective is accomplished thru air displacement from one collapsible and inflatable container under one cover of the volume thru a by-pass tube and control valve into another collapsible and inflatable container under the other cover of the volume. The resu...

A graphic display system in which the lights of an array of lights arranged in dot matrix form are illuminated to produce the illusion of a moving sign displaying letters, words, numbers etc. in which use is made of the phenomenon of beta apparent motion to enable a moving image of a high resolution to be produced with the use of a small proportion for example 1/8, of the number of individual lights that would normally be considered necessary. The lights are preferably arranged in columns, light...

A graphic recorder including a viewable well for holding a recording web in a moist condition. The recorder includes a demountable, transparent well cover and a transparent top. Walls are arranged on the sides of the top and they carry a linear electrode and a roller and simultaneously urge the well cover towards the well to seal the compartment and prevent the escape of moisture.
