Abstract: A switching amplifier of the invention boasts of an enhanced SN ratio in its output and an increased amplitude limit value in its input signal. The switching amplifier has a quantized signal generating section that converts an input signal to generate a quantized signal in the form of a PDM or PWM signal and a constant-current-outputting current amplification section that current-amplifies the quantized signal outputted from the quantized signal generating section. The quantized signal generating section and the current amplification section are formed by the same process. Another switching amplifier of the invention is inexpensive and is not affected by voltage fluctuations in the supply voltage.

Abstract: A toner bottle stores toner in a cylindrical section having an inner circumferential surface provided with a plurality of protruding portions raised inward the cylindrical section. When the cylindrical section is driven to rotate on its central axis, the toner is discharged from the cylindrical section via an outlet. When cross-sections perpendicular to the central axis of the cylindrical section are projected from a longitudinal direction of the cylindrical section, the cylindrical section has an inner circumference provided with one or more regions where the protruding portions are not projected. This prevents the toner from making contact with the protruding portions. Therefore, the toner can be conveyed while suppressing the generation of frictional heat by reducing the resistance between the toner and the protruding portions.

Abstract: An optical device comprises an input polarizer 4, a patterned retarder 5 and an output polarizer 12. The retarder 5 has regions 8 and 9, at least one of which alters the polarization of light from the input polarizer 4. The output polarizer 7 has a transmission axis 12 such that light passing through the regions 8 and 9 of the retarder 5 and through the output polarizer 7 is matched in amplitude, phase and polarization. Such a device may be used as a switchable parallax barrier with an LCD 2 to provide a display which is switchable between an autostereoscopic 3D mode and a 2D mode with the 2D mode having more uniform intensity across the display.

Abstract: A nitride semiconductor laser device has a nitride semiconductor substrate that includes a dislocation-concentrated region 102 and a wide low-dislocation region and that has the top surface thereof slanted at an angle in the range of 0.3° to 0.7° relative to the C plane and a nitride semiconductor layer laid on top thereof. The nitride semiconductor layer has a depression immediately above the dislocation-concentrated region, and has, in a region thereof other than the depression, a high-quality quantum well active layer with good flatness and without cracks, a layer that, as is grown, readily exhibits p-type conductivity, and a stripe-shaped laser light waveguide region. The laser light waveguide region is formed above the low-dislocation region. This helps realize a nitride semiconductor laser device that offers a longer life.

Abstract: For example, fingerprint information read by a scanner is collated with fingerprint information read by a terminal apparatus used by an operator, so that on the basis of the collation result, the operator is permitted to use this scanner. This configuration allows any operator to use the scanner. Further, the fingerprint information and the like temporarily stored for this collation is deleted on completion of the use of the scanner, so that fingerprint information regarded as important personal information is stored only for a limited duration. This avoids the risk of leakage of the fingerprint information. In conventional image processing systems using fingerprint information, the fingerprint information of operators needed to be registered and stored in advance. This has caused the problem of a risk that the stored fingerprint information leaks to the outside, as well as the problem that the use of the image processing systems is limited to those who have registered their fingerprint information.

The image signal is transferred asynchronously from the former block to the latter block through an external memory controller.

Abstract: A multiple view display comprises a display device which displays first and second images in a spatially multiplexed fashion across the display surface.
