    摘要: A secondary electron multiplication target includes first and second porous layers laminated on a signal electrode. The first porous layer is formed of MgF.sub.2 which, having a high secondary electron emitting ratio and a dielectric constant of 6 or less, produces a great number of secondary electrons in response to photoelectrons incident thereupon across the signal electrode. The second porous layer is formed of carbon which has a low secondary electron emitting ratio and hence a high crossover potential, as well as a dielectric constant of 6 or less.

    摘要: A hair dye and hair-dyeing methods using the hair dye are provided. The hair dye comprises, as essential ingredients, (i) a formulation primarily composed of a dye component including indican derived from indigo plants and (ii) a formulation primarily composed of a &bgr;-glucosidase enzyme component. Hair is first mordanted with a dye mordant such as aluminum, iron and the like, and then secondly the prepared hair dye is uniformly applied to the hair either directly or as a mixture of the dye and a proper amount of water. Upon completion of the hair-dyeing, hair is rinsed with water and is finished by drying.
