  • Publication number: 20060048741
    Abstract: A cylinder head of an internal combustion engine is provided with an improved intake port configuration, that improves the efficiency of air intake into a combustion chamber. The engine includes an intake valve which covers an opening of a combustion chamber and which has a valve stem supported by a valve guide. The valve guide is fixed to a curved wall of an intake port leading from a hole in the side of the cylinder head to the intake opening of the combustion chamber. An intake port is configured so that the cross-sectional area thereof reduces with an increasing distance from the intake opening of the combustion chamber, and so that the passage cross-sectional area at a distance equal to about 10% of the total length of the intake port from the intake opening of the combustion chamber is 0.8 times the area of opening of the combustion chamber or smaller.

  • Patent number: 7010745
    Abstract: The image input part (3) in an authoring device (1) reads a plurality of pages of a paper publication and creates images of the pages. In the border eliminating part (9) of the authoring device (1), a common area extraction part (15) extracts the area common to all of the images of the pages. The layouts with respect to at least either text or drawings in this common area of the images resemble one another. The non common-area replacement part (19) replaces the color of the portion outside the common area of the images with the background color of the common area, so as to remove the border outside the common area of each of the images. An image output part (5) in the authoring device (1) outputs the data of the post-replacement images of all of the pages of the paper publication as the contents of an electronic publication.

  • Publication number: 20040172543
    Abstract: Data to be encrypted (301) is partially extracted successively. A result of encrypting a previously extracted portion of the data is used to successively calculate that of encrypting the currently extracted portion of the data successively. Successively calculated results of the encryption are used to generate encrypted data (305). In generating the encrypted data, a finally calculated result of the encryption (PF (z+1)) is attached to the generated encrypted data. The finally calculated result is used as falsification detecting data (308) for detecting whether the data to be encrypted is falsified data.

  • Publication number: 20040024860
    Abstract: Reproduction means of a general-purpose computer (1) reproduces a digital content only when a device ID included in the digital content corresponds to a device ID of a device by which it is intended to reproduce the digital content. When the device ID of the general-purpose computer (1) is altered, a recovery program for recovering an original device ID is downloaded from a recovery program generation server (2), thereby the device ID is recovered. With this arrangement, it is possible to provide a communication system which is capable of recovering a device ID when, for instance, the device ID is altered on account of the reinstall of a program such as an OS or content player.

  • Patent number: 6687521
    Abstract: The present device is equipped with a measurement site holder 3 that is constructed using a negative impression of the measurement site 10. As a result, variation in the measured values caused by the non-uniform distribution of components in the measurement site 10 is reduced, so that variation in the measured values caused by variations in the light path length accompanying variations in the shape of the measurement site 10, and by variations in blood flow or the like that accompany differences in the contact pressure, can be reduced. Since living-body information and measurement parameters for the patient are recorded on a recording medium 11 mounted on a measurement site holder 3 for the exclusive use of the individual patient, the erroneous acquisition of living-body information for individual patients can be prevented, and reproducible measurements can be performed.

  • Patent number: 6644875
    Abstract: Before stopper members (25) of a skew correcting mechanism (10) are evacuated from a sheet conveyor path, sheet conveyor roller pairs (8) rotate a set angle in a direction opposite to the sheet feeding direction such that a sheet is separated from the stopper members (25). The sheet conveyor roller pairs (8) are arranged so that at least one of the rollers of each pair is independently pressed against the other with a force corresponding to the type of the sheet.
