A small-sized, low-loss load drive circuit, an integrated circuit for that drive circuit, and an inexpensive plasma display using that integrated circuit. In the load drive circuit that responds to switching commands to supply a high or low voltage to a load by switching, the source-drain voltage of an output-stage n-type MOS transistor of a flip-flop is supplied between the gate and cathode of a main IGBT. In order to hold this voltage, the power source to the flip-flop is supplied from a main power source or a charge pump power circuit connected at the fixed potential point of the main power source. In addition, a discharge prevention circuit and discharge prevention elements and are provided in order that the potential of the power source can be maintained higher than the positive potential of main power source.

A spinning method for forming pipe bodies of varying diameter. In the spinning method, when a necked portion is formed at the end of the pipe material by the spinning method, working rollers are restricted so as to return immediately before the pipe end instead of being allowed to axially move beyond the end of the working object pipe. The amount of diameter reduction at the pipe end is set to be smaller than that of the most diameter reduced portion connecting to the pipe end. A protruding portion of a so-called bellmouth shape is formed at the working end, thereby preventing generation of fractures originating at the working end of the base portion or the welded portion and generation of wrinkles during the spinning process.

An image processing apparatus which is capable of managing a large number of transfer jobs without using a large-capacity storage device. A transfer job for transferring image information input to the image processing apparatus to at least one destination is performed, and character information is extracted from the input image information. History information indicative of the execution result of the transfer job is generated, and recorded in association with the extracted character information in a storage device. At least one of at least one piece of history information and at least one piece of character information recorded in association with the history information are perused.

An absorbent article using a surface sheet in which a side of the surface coming into contact with a skin is made of a non-woven fabric and a plastic film layer is stacked in a side of the back of the foregoing non-woven fabric, wherein the residence of a body fluid due to a capillary phenomenon or surface tension in an aperture wall part of the foregoing surface sheet is reduced and the body fluid is rapidly moved into a side of a hydrophilic second sheet or absorber as a lower layer, thereby not only keeping dryness and smoothness on the surface but also preventing turning back with a lapse of time. A surface sheet has a structure in which a side of the surface coming into contact with a skin is made of a non-woven fabric, a plastic film layer is stacked in a side of the back of the foregoing non-woven fabric, and a number of projecting parts and recessing parts are formed by embosses and a number of apertures are formed in the side of the surface coming into contact with a skin; and the foregoing apertures are formed in a proportion so as to have an aperture area of from 0.35 to 0.60 mm2 per aperture and an aperture ratio of from 10 to 19%, and the aperture shape is an aperture shape not having an angledly bent corner.

A display control apparatus and a control method for controlling display of a display unit are provided. The display control apparatus detects an orientation of the display unit and controls a display of the display unit in accordance with the detected orientation of the display unit. The screen of the display unit is divided into a first display area, where a display layout is changed in accordance with the orientation of the display unit, and a second display area where a display layout is not changed in accordance with the orientation of the display unit. The display control unit makes the second display area display a first window which changes in accordance with a function to be executed, and makes the first display area display a second window which does not change in accordance with a function to be executed.

The present invention provides an image processing apparatus that realizes fast image processing in a distribution system equipped with a single mass storage device that reduces the cost for required hardware, and a method for controlling such an image processing apparatus. To accomplish this, the image processing apparatus includes a mainboard, a subboard connected to the mainboard via a bus, and a hard disk 6 that is connected to the subboard and indirectly connected to the mainboard via the subboard and that stores image data. When an access request to the hard disk is generated, in the case of data transfer between the hard disk and the mainboard, normal access is employed. On the other hand, fast access is employed in the case of data transfer between the hard disk and the subboard.

Disclosed is an information processing apparatus equipped with first and second CPUs, as well as a method of controlling this apparatus. When the first CPU launches an operating system for managing a virtual memory area that includes a first cache area for a device, the first CPU generates specification data, which indicates the corresponding relationship between the first cache and a second cache for the device and provided in a main memory, and transfers the specification data to the second CPU. In accordance with the specification data, the second CPU transfers data, which has been stored in the device, to a physical memory corresponding to a cache to which the first CPU refers. As a result, the first CPU accesses the first cache area is thereby capable of accessing the device at high speed.
