Abstract: A workpiece holding device includes a workpiece support surface and a blow suction unit. The workpiece support surface includes suction holes formed therein. A workpiece placed on the workpiece support surface is adsorbed by the suction holes. The blow suction unit includes an ionizer that ionizes gas (for example, air), a jet outlet that jets the gas toward the workpiece and a suction inlet. The gas blown onto and reflected off the workpiece is suctioned through the suction inlet. While blowing the ionized gas onto the workpiece, the blow suction unit is moved relative to the length direction of the workpiece.

Abstract: An image processing system includes a host computer which generates print data and a printer which prints an image based on the print data. The host computer sets attribute information which indicates a part of the print data which is allowed to be visualized and a part of the print data which is prohibited to be visualized. In addition, the host computer also sets authentication information required for reading the part prohibited to be visualized, and transmits the print data, the attribute information, and the authentication information to the printer. The printer prints a visual image of the part allowed to be visualized on a paper medium provided with an RFID chip and stores the part prohibited to be visualized in the RFID chip. In addition, the printer prints the information stored in the RFID chip on another paper medium as a visual image after authentication with the authentication information.

Abstract: [PROBLEMS] To prevent generation of heat by friction in a phase varying device of the engine of an automobile. [MEANS FOR SOLVING PROBLEMS] The phase varying device of an engine comprises an outer casing section (10) having a sprocket (12) for transmitting rotation of the crankshaft of the engine, an inner casing section (20) capable of rotating relatively to the outer casing section and coupled with a cam shaft (2) for opening/closing the intake valve or the exhaust valve of the engine, and an intermediate member (30) meshing with the outer casing section and the inner casing section through a helical spindle, wherein relative rotation is generated between the outer casing section and the inner casing section by moving the intermediate member in the axial direction thus varying the open/close timing of the intake valve or the exhaust valve.

Abstract: An image output apparatus capable of preventing occurrence of quality degradation problem due to fixing failure such as fixing offset at a low cost, by rotating fixing rollers at timing other than that of paper discharge processing. An engine transfers a toner image generated based on image information onto a print sheet, and fixes the transferred toner image to the print sheet by a fixer with fixing rollers. A number of print sheet detector detects whether or not the number of discharged pages has become a predetermined number, and if the number of discharged pages has become the predetermined number, the fixing rollers are rotated for a predetermined period after the completion of page discharge, by an instruction of post rotation instructor.

Abstract: When a printer receives print data in the form of PDL, commands are analyzed and intermediate data is stored in a page buffer (102). Rotation of a polygon mirror is started at this time by a scanner pre-rotation command unit (107), after which bitmap data is expanded by a bitmap expanding processing unit (103) and printed. When printing starts, the polygon mirror is already rotating. This makes it possible to shorten first-page discharge time.
