Abstract: A hair-growth adjusting light emitting device includes a device body, a light-emitting unit attached to the device body, and a locking unit for locking the light-emitting unit to the device body. The device body has a main capacitor, a device body connector, an electric power switch, a release switch, and an electric power supplying part. The light-emitting unit has a light-emitting body and a light-emitting body side connector. Furthermore, the hair-growth adjusting light emitting device includes a release restriction mechanism for preventing the light-emitting unit from being released by the release button when the electric power switch is at a power-on position where the electric power supplying part feeds the electric power to the main connector, and a power-on restriction mechanism for preventing the electric power switch from moving to the power-on position when the light-emitting unit is detached from the device body.

Abstract: A modulating light having a wavelength of 600 nm to 1000 nm excluding a range of 870 nm to 910 nm is irradiated to a portion around hair roots such that a light absorptive component existing in a human body around the hair roots absorbs the light for modulating hair growth. The light having the wavelength in the above range enhances hair growth free from causing inflammation, yet safely and gentle to skin.

Abstract: A modulating light having a wavelength of 400 nm to 600 nm is irradiated to a portion around hair roots at an energy of 0.01 J/cm2 to 1 J/cm2 over a time period of not more than 1 ms as a flash light such that a light absorptive component existing in a human body around the hair roots absorbs the light for modulating hair growth without causing substantial adverse effect.

Abstract: A hair growth modulation device is configured to impart a suitable quantity of irradiated light to a target site while lowering the irradiation intensity required by a light irradiator that generates modulating light for modulating hair growth. This device is provided with a hair follicle approximating means that causes hair follicles of body hairs at the target site to approach the skin surface, thereby enhancing the irradiation efficiency of modulating light irradiated to the hair follicles.

Abstract: A hair growth modulation device is able to detect that a site to be irradiated with modulating light for modulating growth of body hair is a skin in a non-contact manner. This device has a modulating light irradiator 1 for irradiating modulating light, a water content meter 2 for measuring a water content of a target site, and a determinator 3 for judging whether or not to irradiate the modulating light based on the result of the water content meter 2. The water content meter 2 is provided with a measurement light irradiator 6 for irradiating near infrared measurement light having a wavelength of 1300 nm to 2000 nm towards the target site, a light receiving element 7 for receiving light reflected from the target site and converting it to an electric signal, and a signal analyzer 8 for analyzing the electric signal from the light receiving element 7 to obtain a spectrum of the reflected light and to estimate the water content from that spectrum.

Abstract: A two-cycle engine includes a crank case, a crank shaft carried by the crank case, intake reed valves attached to the crank case, a plurality of balance weights rotating in association with the crank shaft and a plurality of balance rotating shafts bearing the balance weights. In arrangement, the balance weights and the balance rotating shafts are arranged outside the outermost intake reed valves in the axial direction of the crank shaft. In view of the axial direction of the crank shaft, the rotating axes of the balance weights and the center portions of the intake reed valves are arranged on opposing parting planes of the crank case. Thus, it is possible to miniaturize the size of the engine in view of the axial direction. Further, the balance weights can be carried by the balance rotating shafts without being lengthened.
