摘要:
An image forming apparatus including a conveyance unit to intermittently convey a recording medium in a conveyance direction, a carriage movable in a main scanning direction and including a recording head, a conveyance path having a curved portion provided downstream from an imaging range of the recording head, a first discharge member provided downstream from the imaging range to discharge the recording medium, and a second discharge member provided downstream from the first discharge member and having a nip to sandwich the recording medium to discharge the recording medium. A length of the conveyance path extending from a downstream edge of the imaging range to the nip is longer than a maximum length of the recording medium usable in the image forming apparatus to prevent a leading edge of the recording medium from being sandwiched by the second discharge member when the carriage performs last scanning movement.

In an image forming apparatus, an AC bias is supplied to a conveyance belt, and the amount of charge on the printing side of a recording sheet is decreased. The charge of positive polarity and the charge of negative polarity which are different from each other are generated on the printing side of the sheet, so that both the charges are cancelled by each other and the charge on the printing side of the sheet is eliminated. Moreover, the charge eliminator eliminates the charge on the printing side of the sheet by the time the sheet is electrostatically attached to the conveyance belt and conveyed to a position where the sheet confronts the head.

In a workpiece grinding method, a grinding allowance of a predetermined width (T) at at least an end surface portion 21 of a workpiece W is removed with a grinding wheel 10 (or 32) by rotating the workpiece W having a cylindrical portion 20 and the end surface portion 21 perpendicular thereto, by rotating the grinding wheel 10 (or 32) supported rotatably about an axis extending in parallel with the axis of the workpiece 10 (or 32), and by moving the grinding wheel 10 (or 32) relatively to the workpiece W. The method comprises a first grinding step of grinding the end surface portion 21 to an approximately right triangle shape in section by infeeding the grinding wheel 10 (or 32) from a grinding start position (S), where the grinding wheel 10 (or 32) overlaps the circumferential surface of the end surface portion 21 through the predetermined width (T) or a narrower width, toward an infeed end position (E) on the side of the cylindrical portion 20 in an oblique XZ-direction; and a second grinding step of removing a grinding allowance of the approximate right triangle shape in section left without being ground at the first grinding step, by feeding the grinding wheel 10 (or 32) in an approximately axial direction of the workpiece W.

A wireless LAN system includes a base station, a first terminal station that is permanently connected to the base station, and a second terminal station that is temporarily connected to the base station. The base station and the first terminal station perform wireless communications by using a permanent encryption key. The base station and the second terminal station perform wireless communications by using a temporary encryption key. The temporary encryption key is invalidated, for example, when a predetermined time has elapsed.

The invention provides a color cathode ray tube using a shadow mask capable of avoiding ruptures or cracks during press-working. The shadow mask has an apertured region having color selecting apertures, and an unapertured region which surrounds the apertured region. A skirt portion is bent from the unapertured region in the direction of the tube axis. The shadow mask has at least two inclined surfaces in a boundary portion between the unapertured region and the skirt portion.

A predetermined-area management system is configured to communicate with a communication terminal. The predetermined-area management system includes: a storage unit that stores image identification information for identifying image data and predetermined-area information for identifying a predetermined area in the image data in association with each other; a receiving unit that receives image identification information that is transmitted from the communication terminal; an extraction unit that searches the storage unit by using the image identification information received by the receiving unit so as to extract associated predetermined-area information; and a transmitting unit that transmits, to the communication terminal, the predetermined-area information extracted by the extraction unit.
