A generating unit generates a plurality of ultrasonic cross-sectional images at a plurality of angles when an ultrasonic wave emitting surface in an ultrasonic probe is rotated. A regenerating unit saves information on the angle of the ultrasonic wave emitting surface when a predetermined condition is satisfied, and rotates the ultrasonic wave emitting surface from the angle of the ultrasonic wave emitting surface different from the saved angle information to the angle based on the saved angle information.

An image reading apparatus includes a casing, a light emitting section, a substrate, a support member, and a light guide. The light emitting section includes plural point light sources disposed in a row. The light emitting section is installed to a first face of the substrate. The support member is installed to the casing and supports a second face of the substrate at a projection portion where a position of the light emitting section is projected at the second face of the substrate. The light guide is installed to the casing adjacent to the light emitting section, and guides light from the light emitting section to a read-face.

An image scanner includes a scanning unit that scans a white scanning member via a contact glass on one line basis when the image scanner is powered on and outputs image data of the white scanning member, and a determining unit that determines whether at least one of the contact glass and the white scanning member has dirt or a scratch thereon by comparing the image data with reference data on one line basis. The reference data is acquired by scanning the scanning member in a situation that there is no dirt or scratch on the scanning member.

In a safety shoe provided with a toecap, a vamp, an insole, and a two-layer structure sole, the a two-layer structure sole includes an outsole part comprising a high hardness rubber material and a midsole part, laminated in the above outsole part, comprising a low hardness sponge rubber material and has a heel part. The outsole part is fused integrally with the midsole part by vulcanization molding, and the upper circumferential edge of the outsole part is fused integrally with the lower circumferential edge of the vamp by the vulcanization molding described above. Since the outsole part in a side in contact with the ground has a high physical strength and is excellent in an oil resistance, a chemical resistance and a heat resistance, and the midsole part in an inner side has a cushioning property, the shoe is less liable to bring about fatigue even after wearing it for a long period of time. Further, a weight of the whole safety shoe can be lightweight, and a durability of the whole safety shoe can be elevated.
摘要:
A method for producing a novel phthalocyanine compound which excels in yield and purity, allows no introduction of a chlorine atom into the phthalocyanine skeleton, and possesses relatively bulky substituents is provided. This method is characterized by causing an orthophthalonitrile compound having a substituent exhibiting smaller .sigma..sub.p values than .sigma..sub.m values in the Hammett's rule to react with a metal oxide in the presence of a compound forming in the aqueous solution thereof at 25.degree. C. an acid or conjugate acid having a dissociation index pKa (the logarithmic value of the reciprocal of the dissociation constant of the acid or conjugate acid) of not more than 7.0.
