    摘要: An improved silver halide photographic material having at least one layer of a light-sensitive silver halide emulsion that is spectrally sensitized with a sensitizing dye of the following general formula (1) to light having a wavelength of 750 nm and above. Said silver halide emulsion is prepared by a process which comprises generating silver halide grains by adding a solution of a water-soluble silver salt and a solution of a water-soluble halide to a solution containing a protective colloid, aggregating the generated silver halide grains with a polymeric flocculating together with the protective colloid, and removing the dissolved matter; ##STR1## where Z.sub.1 and Z.sub.3 each represents the non-metallic atomic group necessary to form an optionally substituted benzothiazole, benzoxazole, naphthothiazole or naphthoxazole nucleus; R.sub.1 and R.sub.2 each represents a saturated or unsaturated aliphatic group; Z.sub.2 represents a 5- or 6-membered ring of carbon atoms; A represents a hydrogen atom when Z.sub.2 is a 6-membered ring; X.sup..crclbar. is an anion; and n is 1 or 2.

    摘要: The development of a skin-whitening agent which has a lower molecular weight, can be synthesized through a fewer steps and can be produced at low cost has been demanded. Thus, it is provided by the present invention a skin-whitening agent including one or more compounds selected from the group consisting of 4-cis-hydroxyproline and its derivative and/or its salt, a skin-whitening composition for external formulation to the skin, a cosmetic composition and a pharmaceutical composition, each of which contains the skin-whitening agent of the invention, and a cosmetic method for whitening the skin, which includes a step of administering one or more compounds selected from the group consisting of 4-cis-hydroxyproline and its derivative and/or its salt. In the skin-whitening agent and the cosmetic method for whitening the skin of the invention, the 4-cis-hydroxyproline may be 4-cis-L-hydroxyproline and/or 4-cis-D-hydroxyproline.

    摘要: A differential transmission connector unit is disclosed that includes a first differential transmission connector including a first electrically insulating block body; and first signal contact pairs and first ground contacts arranged alternately in a row in the first block body; and a second differential transmission connector including a second electrically insulating block body; and second signal contact pairs and second ground contacts arranged alternately in a row in the second block body. The first differential transmission connector is connected to the second differential transmission connector with the first signal contact pairs and the second signal contact pairs being in contact with each other and the first ground contacts and the second ground contacts being in contact with each other. One of the contact surface of each first ground contact and the contact surface of the corresponding second ground contact is a rolled surface, the contact surfaces contacting each other.
