Abstract: In a screen displayed on site in a data format of image data, if a portion of the screen is changed, from among the image data of the entire screen, only an image data subjected to the change is converted to a vector graphics and is transmitted to a remote site via a network. At the remote site, the transmitted vector graphics is reconverted to the image data and is displayed. Further, information necessary for searching an image data is transmitted in association with a vector graphics. This allows a search to be made only from a data which actually requires to be displayed at the remote site.

Abstract: This invention provides a process control simulator configured to efficiently debug a plant control system. A computer stores simulated data generated by a model executing part to a time-series memory area. A programmable controller stops input from the input-device interface when there is a virtual input/output request received. A virtual input/output processor sets simulated data from a time-series memory area of the computer to a time-series memory area of the programmable controller. A program executing part sets simulated data from the time-series memory area to a memory area at the same resolution as an arithmetic operation period of program execution and executes the program. Control output as a result of the execution is fed back to the model executing part of the computer, and the computer calculates simulated data as process value at this timing, and stores the data to its time-series memory area.

Abstract: Documents used for process control can be managed and maintained from a document server and a terminal. In order to update the documents quickly so that an operated process is always kept in the most preferable state of operation, the document server stores and manages production documents used for actually controlling and monitoring a control system plant, whereas the terminal system is used to refer and edit plant documents. The terminal can synchronize contents of the plant documents in the document server with those in the control system before storing the synchronized plant documents in the terminal.

Abstract: A high-definition plasma display panel and its manufacturing method. Luminance is increased by increasing surface area of a phosphor layer without reducing a discharge space of a discharge cell. For formation of the phosphor layer, an organic binder is made by dissolving, through heating, at least an organic solvent and a plurality of resins of different solubilities with respect to the organic solvent, and phosphor paste is made of this organic binder and phosphor particles. A recessed and projected part is formed of spaces formed by burning out gelled substances formed by the resin with low solubility in a phosphor film, thereby increasing the surface area of the phosphor layer. Consequently, increased luminance is obtained.

Abstract: An optical disk molding apparatus and method are provided which prevent data formed on a molded object from being damaged and prevent quality deterioration of the molded object. There are provided a mold moving device, a first gas supply device, and a controller, whereby a first release space part is formed by opening molds from a mold clamp state by a movement distance not damaging a data transferred face of the optical disk, and a gas is supplied to the first release space part at a point in time when the first release space part is formed, thereby totally separating the optical disk and a stamper from each other. No damage is caused to a data transferred face at the point in time when the first release space part is formed. Since separation between the optical disk and the stamper is performed via pressure of the gas after the first release space part is formed, data is prevented from being damaged over the data transferred face of the optical disk in its entirety.
