Abstract: The hair growth promoter of the present invention contains extracts from two or three of mulberry bark (mulberry root bark of Morus bombycis Koidzumi and Morus alba Linne or a plant of the same genus as that of them), leaves of persimmon (Diospyros Kaki Thunb) and leaves of paulownia (Paulowinia tomantosa Steud. or plants of the same genus as that thereof) as the active ingredients for restoring or growing hair.The hair growth promoter of the present invention has an effect of accelerating the proliferation of the human hair follicle cells which constitute the human hair follicle and which form the hair and also an effect of accelerating the hair growth in mice. When the hair growth promoter is applied to the human beings, excellent effects of preventing the hair from falling out and accelerating the hair growth are obtained. Thus, the hair growth promoter of the present invention is effectively usable for the treatment or prevention of an alopecia such as premature alopecia or alopecia diffuse.

Abstract: An electrodeless discharge lamp includes a discharge gas sealed in a lamp tube. The discharge gas includes a halide of rare earth metal. An auxiliary electrode is disposed on or adjacent to an outer periphery wall of the lamp tube such that the auxiliary electrode is capacitively coupled to an interior space of the lamp tube. A main induction coil is wound around the lamp tube and receives power from a first high frequency power source. The auxiliary electrode receives power from a second high frequency power source. In operation, the electrodeless discharge lamp attains smooth lighting upon starting or restarting.

Abstract: A metal vapor discharge lamp includes an arc tube having on an inner surface a coating of multi-layer construction including a layer preferably facing the interior discharge space of the arc tube and formed with a strongly covalent bonded material and at least another layer made to have a function of shielding water, whereby reaction of enclosed materials with the arc tube and oozing of water from the arc tube can be prevented, and cracking and peeling of the coating can be effectively prevented from occurring.

Abstract: A composition of soap compounded with a garlic extract containing thiamine, a thiamine derivative having vitamin B.sub.1 activity or a salt thereof is disclosed. The soap is effective for improving atopic dermatitis.

Abstract: An electrodeless discharge lamp includes a single type auxiliary electrode for preliminary discharging, disposed on or adjacent to outer peripheral wall of lamp tube at a position for being electrostatically coupled to interior space of the tube, and supplied with a power from a second high frequency power source other than a first high frequency power source supplying a high frequency power to a main induction coil on the tube, whereby the lamp is made to attain an excellent startability without requiring any large size high frequency power source.

Abstract: A high intensity discharge lamp device is formed from materials which form complex halides enclosed in an arc tube in addition to rare gas and metal halides, to realize the high reproducibility of luminous color called for in visual machines and devices and so on.

Abstract: A high pressure discharge lamp wherein an arc tube is so formed at least at one end portion as to satisfy a predetermined condition, unlike any known configuration and dimensions of the arc tube end portion, to restrain occurrence of acoustic resonance phenomenon for reducing zones in which the phenomenon occurs at least to be below 50% and effectively preventing any adverse influence of the phenomenon on discharge arc column.
