Abstract: At a time T131, a wireless communication apparatus 11A determines to transmit a data packet, and then performs interference signal detection for a period TA. At a time T132 preceding a time T133 at which the period TA has elapsed since the time T131, the wireless communication apparatus 11A detects a data packet d21 (an interference signal). At a time T134 at which a period TB has elapsed since the time T132 at which the interference signal has been detected, the wireless communication apparatus 11A starts transmitting a data packet d11 to a wireless communication apparatus 12A. At a time T136, the wireless communication apparatus 11A completes the transmission of the data packet d11.

Abstract: Preparations containing minoxidil at a high concentration which scarcely show the precipitation of crystals even at low temperatures and have a high stability.

Abstract: A liquid composition which comprises minoxidil and arginine contained in a liquid medium, can prevent color development of a minoxidil-containing liquid preparation by heat with time and thus has a distinguished preservation stability and improved commercial value.

Abstract: Minoxidil preparations having a sustained action by which a fully satisfactory effect of stimulating hair growth can be obtained when applied once a day.

Abstract: The present invention provides a minoxidil-containing composition which can be prevented from coloring for a long period of time.

Abstract: Preparations containing minoxidil at a high concentration which scarcely show the precipitation of crystals even at low temperatures and have a high stability.

Abstract: There is provided a composition for external use with a reduced skin irritation comprising minoxidil and 0.01 to 2 parts by weight of at least one antihistaminic agent selected from the group consisting of chlorphenylamine maleate, diphenylimidazole, diphenhydramine and a salt thereof per 1 part by weight of minoxidil.

Abstract: Knitted material having chains interlaid between double-knitted loops and knitted in any conventional fashion to form a pattern. Preferably the chainsupporting loops are knitted by rib stitches with wales formed in a series of 1 .times. 1 ribs alternatively constituting the front and back stitches. The courses may include plain stitches with the two loops of the rib stitches disposed at the junction between the rib stitches and the plain stitches being linked to a loop of the plain stitches on the adjacent course.
