Abstract: [Object] To provide a riblet structure that increases resistance reducing performance and is easily manufacturable, and an object including such a structure on a surface thereof. [Solving Means] This riblet structure includes a plurality of wave-shaped riblets on a surface thereof, in which each of the riblets has a smaller peak height as an angle formed between a ridge line and a fluid flow direction becomes larger, a width between peak bases in a direction orthogonal to the fluid flow direction becomes smaller as the angle becomes larger, and an angle formed between a slope of a peak of the riblet and the surface at the peak base or a curvature at the peak base is identical at any position in a cross-sectional shape in the direction orthogonal to the fluid direction.

Abstract: The present invention provides a riblet structure that further reduces drag, which is a sum of turbulent friction drag and pressure drag, and an object including such a riblet structure. An object such as an aircraft, plant, and pipeline includes a wavelike riblet pattern on a surface. The wavelike riblet pattern includes a large number of wavelike riblets. Each of the large number of wave riblets includes a wavelike ridge line, and a height thereof changes cyclically with respect to a fluid flow direction. With such a configuration, drag, which is a sum of turbulent friction drag and pressure drag, can be further reduced.

Abstract: A purpose is, in the case where a nonwoven member is hot pressed around a wire harness to form a protective member, to inhibit rotation of a vehicle body fixing component attached to the protective member while making a cross-sectional shape of the protective member as circular as possible. The wire harness includes a wire harness body containing at least one electric wire and a protective member formed by hot pressing a nonwoven member in a state of covering at least a portion of the wire harness body. The protective member has a protective body that is formed to have a circular cross-sectional shape and a projection forming part that has a partially projecting part formed on an outer periphery.

Abstract: A wire harness includes a wire harness main body having at least one electric wire and a protection material formed by hot pressing a nonwoven material wrapped more than one time around a circumference of at least a portion in a longitudinal direction of the wire harness main body. A slimmed portion is provided to at least one end of the protection material, the slimmed portion being thinner than a middle portion of the protection material so that a portion where an external surface and an internal surface of the nonwoven material make contact with each other is entirely joined in a circumferential direction on a periphery of the wire harness main body.

Abstract: It is an object of the present invention to provide a wire harness that has a simple structure, that can be easily manufactured, and that includes a protective member having an extra-length absorbing function. A wire harness (1) includes an electrical wire bundle (12) and a protective member (21). The protective member (21) is a member obtained by heat-molding a nonwoven fabric, covers a portion in the longitudinal direction of the electrical wire bundle (12), and has a spiral shape or helical shape in which a curved portion is formed with a continuous turn in the longitudinal direction or has a meander shape in which a plurality of curved portions are formed with intermittent turns in the longitudinal direction.

Abstract: In an image reading apparatus for reading an original image using a light source containing a plurality of color components, a control pulse for dimming the light source is generated by pulse-width modulation symmetrically with respect to a reference timing (for example, the central position in one storage time or the storage start timing) in one predetermined storage time of a line sensor.

Abstract: Predetermined additional information is superposed as a dot pattern on image information read by an image scanner, and the image information superposed with the additional information is modulated. The modulated information is demodulated and recorded on a recording medium to perform a series of operations, i.e., to simultaneously satisfy both pattern addition and modulation/demodulation.

Abstract: To control a light emitted from a fluorescent lamp having phosphors with different afterglow properties for different colors, a center of a lighting control signal for controlling the lighting of the fluorescent lamp is controlled to constantly align with the center of a Hsync period so that despite the variation of the lighting time of the fluorescent lamp, a barycenter of the quantity of light from the fluorescent lamp in the Hsync period almost aligns with the center of the Hsync period to reduce the offset of the barycenter.

Abstract: This invention relates to an image reading apparatus which eliminates color misregistration upon reading in the sub-scanning direction, which occurs due to different afterglow or persistence characteristics of the respective colors of a light source upon executing the light quantity control of the light source for illuminating an original. Since the light quantity control of the light source is divisionally done a plurality of times in one accumulation period of a solid-state image sensing element, any deviation of the center of gravity in the quantity of light from the center C of one accumulation period can be minimized, and the color misregistration can be eliminated remarkably.

The image processing apparatus has an addition/output device for adding the weighting factors of a first and a second image data and outputting it; a counter device for counting the image data in the direction of the main scanning or sub-scanning or in both of the directions; and an addition control means for changing the weighting factors in the weighting operation performed in the addition/output device on the basis of the count value of the counter means. As a result, weighting factors can be changed within one combined image. Thus, desired image editing operations can be performed.
