An embodiment of an inkjet may include a plurality of nozzles to eject ink, a pressure chamber individually communicated with each nozzle and filled with ink, a pressure generator to eject ink by applying pressure to the pressure chamber, an inlet including a narrow portion with a flow path narrower than the pressure chamber and structured to supply ink to the pressure chamber, and a circulation flow path structured to discharge ink in the pressure chamber from near the nozzle. Viscosity resistance of the circulation flow path may be smaller than viscosity resistance of the nozzle, and impedance of the circulation flow path may be equal to or more than 0.5 times of the impedance of the inlet.

Inkjet head and inkjet recording device

A method of applying an image processing to two dimensionally-arranged original image data corresponding to an entire image region of a photographed image including a main photographed-subject; comprising steps of determining a main photographed-subject region of the main photographed-subject or a selected region by at least one on the two dimensionally-arranged original image data; setting the entire image region and one of the main photographed-subject region and the selected region as target regions for an image processing; obtaining image characteristics from each of the target regions; calculating a granularity value and a sharpness value for each of the target regions from the respective image characteristics of the target regions, wherein each of the granularity value and the sharpness value is an evaluation criterion standardized with a functional value; and conducting an image processing for the two dimensionally-arranged original image data with reference to the granularity value and the sharpness value.

Image processing method, storage medium, image processor and image recorder

A silver halide photographic material which is in the form of a roll film packaged in a cartridge, and which exhibits superior print stability and is capable of providing prints with superior image quality when printed onto printing paper is disclosed, comprising on a support a red-sensitive layer, a green-sensitive layer and a blue-sensitive layer, wherein the quality value (QC) satisfies the following requirement&#x2267;15.982&#xd7;(100&#x2266;&#x2266;1600)where S is the nominal speed of the photographic speed.

Silver halide photographic material

An ultrasonic diagnosis apparatus comprises a probe having a plurality of transducers for performing transmission/reception of ultrasonic waves; a selection circuit for sequentially selecting the transducers for performing transmission/reception of ultrasonic waves; and an A/D converter for converting a reception waveform signal from the transducer selected by the selection circuit into a digital waveform signal. The apparatus also includes a memory for storing the digital waveform signal converted by the A/D converter in correspondence with the selected transducer; and a read control circuit having a wavefront locus address generator for generating a wavefront locus data corresponding to time-of-flight data between each point in an ultrasonic scanning region and respective transducers to synthesize a wavefront converging on a point in the ultrasonic scanning region (including points which are not located on lines normal to the radiating surfaces of the transducers). The apparatus also includes an output unit for outputting the wavefront locus data to the memory as a read address in order to read waveform samples along the wavefront; and a synthesis circuit for synthesizing the waveform samples read from the memory by a read address from the read control circuit.
