The present invention relates to a hair cuticle caring method or volume enhancing method, which comprises treating hair with a composition containing (A) a cationic surfactant and (B) an organic acid or salt thereof in a combination to give, when an aqueous solution containing 1 mM of each of the components is formed, 40 mN/m or less as the surface tension of the aqueous solution at 27±0.5° C. By the application of the above-described composition, the lift-up of the hair cuticle can be suppressed, the volume can be enhanced softly, moisturized but stickiness-free feeling is imparted and styling ease is improved.

An image forming apparatus including an image carrier that includes a photoconductive layer on which an electrostatic latent image is formed, a charging member that comes in contact with the image carrier and charges the photoconductive layer, and a feeding section that supplies a current to the charging member by applying a vibration voltage with an alternating current component superposed on a direct current component, wherein the alternating current component may contain a first amplitude that eliminates charging non-uniformity when the vibration voltage is applied with a uniform amplitude and a second amplitude that is smaller than the first amplitude.

摘要:
A solenoid valve driving apparatus includes switching means for ON/OFF-controlling application of a direct current voltage to a solenoid of a solenoid valve, and signal outputting means. A first period and a consecutive second period are set as a valve opening operation period of the solenoid valve. When the signal outputting means outputs the PWM signal to the switching means, a duty ratio of the output signal is set to be higher in the second period than in the first period so that a power supplied to the solenoid is larger in the second period than in the first period. As a result, a valve opening operation is performed in the solenoid valve reliably, and loud noise generation during the valve opening operation is suppressed.
