  • Patent number: 6919972
    Abstract: Upon reading an A3-size sample image, a colorimeter that can read A3 size can be used but such A3-size calorimeter is expensive. For this reason, an A3-size recording paper sheet is cut into halves, i.e., two A4-size sample images, which are measured by an A4-size calorimeter. To prevent such troublesome operation, color patches are divided into nearly half groups, and these color patch groups are printed on an A3-size recording paper sheet to have their top positions on the opposite sides. In this way, after one color patch group is measured, the sample image is rotated through 180° and is set on the calorimeter to measure the other color patch group.

  • Patent number: 6904403
    Abstract: In transmission of digital audio data usingIEEE1394, for example, when the audio data is changed from linear PCM to nonlinear PCM, identifier adding means of the transmitting apparatus inserts a silent identifier and nearly zero data for a specific time, and first identifier distinguishing means of the receiving apparatus changes over the output of data processing selecting means from linear PCM processing side to nonlinear processing side when detecting the silent identifier, thereby preventing generation of noise when changing over the data.

  • Patent number: 6781128
    Abstract: An infrared radiation detecting device is constructed using a manufacturing method to increase the infrared radiation absorptance of the infrared radiation absorbing film. The infrared radiation detecting device has an infrared radiation absorbing film. In one embodiment, the infrared radiation absorbing film has a varying film thickness. The film thickness difference between the thickest points and the thinnest points and the spacing between the thickest points within the same plane are set to decrease the effective surface reflectance cause by the interference or scattering effects of the infrared radiation. Preferably, the film thickness differences between the thickest points and the thinnest points are equal to or greater than ¼ of the wavelength of the infrared radiation being measured, and the spacing between the thickest points within the same plane is shorter than the wavelength of the infrared radiation being measured.
