Abstract: As a result of extensive studies on NAD(P)H oxidase inhibitors, the present inventors found that a quinolone derivative having, at the 2-position, an alkyl group substituted with a heteroatom or the like has an excellent NAD(P)H oxidase inhibitory activity, and accomplished the present invention. The compound of the present invention has a reactive oxygen species production inhibitory activity based on the NAD(P)H oxidase inhibitory activity, and therefore can be used as an agent for preventing and/or treating diabetes, impaired glucose tolerance, hyperlipidemia, fatty liver, diabetic complications and the like.

Abstract: An electric shaver including a display that indicates when it is time to clean the shaving debris accumulated on a shaving debris receiving part that is covered by an outer cutter frame of the shaver. A counting device of the shaver counts the use time (or the load current) of the motor that drives the inner cutter so that a control device compares the counted use time with a preset reference value; and when the counted use time reaches the preset reference value, the control device judges that the time for cleaning has arrived and actuates the display so that the display shows that it is time for cleaning. Thus, the user detaches the outer cutter frame and removes the shaving debris from the shaving debris receiving part in which a light-receiving devices is embedded.

Abstract: An electric rotary razor including at least one outer cutter which has slits for whisker entry and at least one inner cutter having a plurality of cutter blades. Each one of the cutting blades is inclined in the rotational direction of the inner cutter and has a cutting edge surface at its upper end that slide on the bottom surface of the outer cutter. The cutting edge surface is thinner than the cutter blade or the cutter blade can have a recess beneath the cutting edge surface. Thus, sheared whiskers are prevented from sticking to the cutter blade of the inner cutter.

Abstract: An electric razor with a cleaning cover fitted on the inner cutter. The cleaning cover has slits which correspond in position to the blades of the inner cutter, and the blades of the inner cutter can pass through the slits when the cleaning cover is fitted on the inner cutter; and once the cover is fitted on the inner cutter, the surface of each blade is in contact with the inner surfaces of the slits. The razor is used with the cleaning cover on, and when after shaving the cleaning cover is lifted, the facial hair that has been cut and is adhering to the blades of the inner cutter are removed by the cleaning cover, thus cleaning the inner cutter.
