Abstract: A brake device includes a brake pedal, a pedal operation detection section, a tank section, an actuator, a master cylinder, a brake fluid path and a reaction force generating section. The master cylinder includes a cylinder section that forms a storage chamber for storing brake fluid and a piston rod that connects to the brake pedal and pushes out the brake fluid stored in the storage chamber and discharges the brake fluid to an outside of the cylinder section by moving a distance corresponding to an amount of operation of the brake pedal. The brake fluid flow path guides the brake fluid discharged from the storage chamber by being pushed out by the piston rod to the tank section. The reaction force generating section includes an elastic member that generates a reaction force on the brake pedal by elastically deforming according to the amount of operation of the brake pedal.

Abstract: An object of the present invention is to provide a composition for stimulating an increase in an androgen. The composition for stimulating an increase in an androgen contains compound K. The composition for stimulating an increase in an androgen contains a fermentation product and/or enzymatically degraded product of ginseng as an active ingredient.

Abstract: Provided is a substance which is a safe material such as a food component and an extract of a natural product and has a stronger effect of ameliorating a cerebral function (effect of ameliorating a metabolism of monoamines as an intracerebral neurotransmitter and ameliorating deterioration in memory and learning due to hypofunction of a cholinergic neuron). The present invention provides a composition for ameliorating a cerebral function, comprising an alkali-stable lipid from an acetic acid bacterium, N-acylsphinganine or N-2?-hydroxypalmitoyl-sphinganine, as an active ingredient.
