Abstract: On an outer circumferential portion of a piston band, in a natural state before being disposed in a cylinder, a large diameter part is formed on a side close to a distal end portion of a piston rod or on a side far from the distal end portion, a medium diameter part having a diameter smaller than that of the large diameter part is formed on a side far from the distal end portion or on a side close to the distal end portion, and a small diameter part having a diameter smaller than that of the medium diameter part is formed between the large diameter part and the medium diameter part.

Abstract: An image processing system includes first and second devices. The first device converts print data described in a page description language into intermediate data. The second device converts the intermediate data into raster data and supplies the raster data to a printer. The first device includes a shape modifier, a first generator, and an output section. The shape modifier divides plural graphic elements indicated by the intermediate data within a unit of output into groups, and modifies, among the graphic elements in each of the groups, a shape of first-type graphic elements having a specific component into a shape without having an overlapping portion between the first-type graphic elements. A color of the specific component is superimposed on a color of an underlying graphic element. The first generator generates an item of mask information for identifying a logical OR shape of the first-type graphic elements included in each of the groups.

Abstract: A printer includes an intermediate-data processor and an output-print-data generating unit. The intermediate-data processor performs a process in such a manner that intermediate data is generated from input print data. The output-print-data generating unit generates output print data from the intermediate data. The intermediate-data processor specifies one from intermediate-data generating schemes for a component of an object, on a basis of predicted generation performance of the output-print-data generating unit, and generates the intermediate data. The predicted generation performance is predicted for respective cases of generating the intermediate data by using the intermediate-data generating schemes.

Abstract: A print image processing system includes plural logical page interpretation units, a caching interpretation unit, and a print image data generation unit. The plural logical page interpretation units interpret different logical pages in print data in parallel to obtain interpretation results, and output the interpretation results. The caching interpretation unit interprets an element to be cached which is included in each of logical pages in the print data to obtain interpretation results, and stores the interpretation results in a cache unit. The print image data generation unit generates print image data of the logical pages using the interpretation results of the logical pages output from the logical page interpretation units and the interpretation results of the elements to be cached stored in the cache unit. The print image data generation unit supplies the generated print image data to a printer.

Abstract: A print document processing system includes a cache apparatus and plural data processing apparatuses. Each data processing apparatus includes an image data creating unit and a reservation request transmission unit. The cache apparatus includes a cache memory, a memory, and an area reservation unit. The image data creating unit creates image data for each document element of print document data. The memory stores use condition information and cache priority of the document element for each document element. Upon receipt of a reservation request for reserving a storage area for image data of a first document element from a data processing apparatus, the area reservation unit reserves the storage area by selecting a second document element, which has a lower cache priority than the first document element and which is currently being used by any of the data processing apparatuses, as a document element to be evicted from the cache memory.

Upon receipt of the CREATING response, the controller performs control to use the image data after created or cause the image data creating unit to create the image data.

Abstract: An image processing system includes plural intermediate data generators, a first memory, and plural drawing data generators. Each of the plural intermediate data generators interprets an assigned data portion of document data, written in a page description language, to generate intermediate data. The first memory stores the intermediate data generated by each of the plural intermediate data generators. Each of the plural drawing data generators reads out the intermediate data from the first memory and generates drawing data in accordance with the read out intermediate data. The drawing data includes information about each pixel included in a printed image. Once an amount of intermediate data stored in the first memory exceeds a first threshold that is set in advance, the plural drawing data generators start reading out the intermediate data from the first memory.
