Abstract: A metal part is uniformly cooled by uniformly breaking a vapor film formed when a cooling liquid vaporizes on a surface of the metal part. Oscillations are applied to the vapor film formed on the surface of the metal part, whereby the vapor film is broken without the stirring of a cooling liquid 1. The cooling liquid 1 is stirred after the vapor film begins to be broken, whereby bubbles formed by the breakage of the vapor film are caused to diffuse in the cooling liquid 1.

Abstract: In a side plate (52) of a retainer (50), a jig insertion groove (70) is cut at an upper end portion of its front edge. A releasing jig (J) is insertable into a gap between the bottom surface of the jig insertion groove (70) and a vertical front edge of a recessed surface (27) of a female housing (20). If the releasing jig (J) is rotated so as to be pried, the retainer (50) is pushed back diagonally downward along a guide groove (60) and reaches a temporary retaining position.

Abstract: A connector has a retainer (6) with a housing lock (4) engageable with a housing (3) and a terminal lock (5) cantilevers forward from a bottom side of the housing lock (4) to lock female terminal fittings (1). Restricting portions (7) are formed on a surface of the terminal lock (5) to face the housing (3). The restricting portions (7) can contact bottom end surfaces (3A) of the opposite side walls of the housing (3) along the width direction, thus preventing the terminal lock (5) from entering cavities (2) to hinder the insertion of the female terminal fittings (1) when the female terminal fittings (1) are inserted into the cavities (2).

Abstract: An anisotropic scattering sheet comprising at least an anisotropic light scattering layer, wherein the anisotropic light scattering layer comprises a continuous phase and a dispersed phase which are different in refraction index from each other, the mean aspect ratio of the dispersed phase is more than 1, and the major axis directions of each dispersed phase are oriented to a given direction, and wherein the sheet is a heat-treated sheet. In the treatment, the heat-treating temperature may be not less than 70° C., and in the typical treatment, heat-treatment is conducted after the sheet is oriented by a monoaxial stretching through roll calendaring. The present invention ensures to provide an anisotropic scattering sheet stably usable for a long period of time without causing luminance unevenness.
