Title: Format converting system
Inventor: HATASAWA KIKUO
IPC: B41J5/30
Filed: 1984-08-08
Abstract: PURPOSE:To attain 90 deg. conversion of format by applying dot expansion once in a direction orthogonal to raster direction, reading dot data of a full dot memory in the raster direction in the unit of words, reediting it into a format data and storing it in a format overlay memory. CONSTITUTION:When the dot expansion direction is orthogonal to the raster direction, it is required for turning processing of the format. In this case, a format overlay processor 26 applies dot expansion to the format data in the Y direction. Then the format overlay processor 26 reads the dot data from the full dot memory 27 in the raster direction in the units of words, it is edited again into the format data and stored in the format overlay memory 25. Since the format data stored again is turned by 90 deg., when it is applied with dot expansion in the raster direction on the full dot memory 27, it is read in the direction of raster in the unit of words and transmitted to a laser beam printer without modification. Thus, the reduction of print speed is not incurred.

Filed: 1982-09-27
Abstract: PURPOSE:To attain connection anywhere on a common bus independently of the priority of the bus, by comparing a priority code ORed with each device with the priority code of the own device, in the bus competition method of an electronic computer system. CONSTITUTION:When an optional priority code is distributed to each device and a device competing a bus sets a flip-flop circuit FF1 and then FF2 in the bus competition, the priority code is outputted from the device onto the bus, where the code is ORed. The code data ORed on the bus is inputted to a comparator COMP-A of the respective devices and compared with a high-order switch data of the device. For example, when both the signals of one device are coincident and they are not coincident on other device, the setting of the FF2 of the other device is disconnected, the data to a bus of a switch group SW outputted from the other device is stopped, and the data on the bus has the priority code of one device only.
