A graphic editor for performing various editing processes such as inputting, moving, copying, and deleting a graphic pattern and a line on a display screen in a graphic editing system such as a CAD, etc. The graphic editor realizes a user interface for simultaneously selecting an object to be processed and a function, thus improving the efficiency of the editing operation. The editor comprises an area specifier for specifying an area as a rectangle having a diagonal whose start and end points ar...

A graphic display system, including a uniquely designed three or four element structure, forming a semi-graphic display and associated electronic components, such components being mounted in fixed relation to the semi-graphic display, for permitting the use of high density, non-illuminated, semi-graphic displays while retaining the information capability of a full functional graphic. The system includes a frame designed to support structural elements therein and to protect electrical wiring conn...

A graphic method for preparing a surface map used to synthesize a masking layer. The proposed structures on a semiconductor surface are mapped as trapezoidal figures on a numerical grid. The first grouping step groups trapezoids into a plurality of groups based on Ymin, and groups are then internally sorted based on Xmin. A to-be-judged group is selected. A intra-group judging step uses a trapezoid as a to-be-judged figure in order of sorting, and trapezoids sorted after the to-be-judged trapezo...

The rendering performance of a graphic processor is improved by effectively using a data bus. An externally-input graphics command is stored in a work memory via the data bus. A display data generation section receives a graphics command stored in the work memory via the data bus, decodes the received graphics command, and outputs the display data to the data bus. An image display section receives display data stored in the work memory via the data bus, and displays an image on a display device....

A versatile, economical, and structurally simple annunciator for use with a fire detection system or the like is provided which requires only a single connection with the detection system, which can be configured as desired, and which allows additional annunciators to be connected thereto. The preferred annunciator is particularly suited for use with a detection system producing data signals representative of abnormal conditions such as fire, unauthorized entry, or the like. The preferred annunc...

A graphic calculator (10) for use in technical drawing has means for selectively displaying one of a plurality of sets of division markers wherein each set corresponds to a set of scaled division markers of a particular scale rule. Such a calculator effectively provides a scale rule whose divisions may be altered as desired. Also disclosed is an electronic protractor having a transparent cross-hair viewer for accurately locating the protractor over the lines forming the angle to be measured and ...

A peripheral device for a computer is disclosed, which employs desired code setting means for determining a desired code and a comparator for comparing the thus determined code and a command from a host computer, whereby the control operation can be smoothly effected by the command from the host computer. Also, a graphic printer is provided as a peripheral device which employs a plurality of sampling clocks of which the phases are different from that of a reference sampling clock. These sampling...

The present invention provides a graphic balancer comprising, in units of bands, level adjusting means (operational amplifiers 1L and 1R, resonators 2L and 2R, and volume controls 3L and 3R) for increasing a level of a sound signal of one of two stereo channels which are divided into a plurality of bands while synchronously decreasing a level of the other, so that localization of a sound image can be shifted in individual bands. As one embodiment of the present invention, a graphic balancer in w...

A display device is mounted to bridge at least one bowling lane, with the support braces of a support for a frame of a panel masking unit being affixed on either side of the lane or lanes. In one embodiment, at least two panel masking units are mounted to bridge adjacent lanes, with one support brace serving as a common support for the two adjacent panel masking units. The frames are mounted on the supports for pivotal movement between a vertical and a horizontal position, with the center of gra...
