Title: Melanization inhibitory drug for external use
Inventor: MOTONO MASAHIRO
IPC: A61K8/00
Filed: 1987-02-25
Abstract: PURPOSE:To obtain a drug for external use, containing kojic acid, having increased water solubility and included in maltosylcyclodextrin and having great melanization inhibitory effects. CONSTITUTION:The titled drug for external use containing kojic acid included in maltosylcyclodextrin. The above-mentioned included kojic acid is obtained by dispersing maltosylcyclodextrin in water, stirring the dispersion while slowly adding the kojic acid thereto and completely dissolving both. Since water solubility of the kojic acid is increased by the treatment, even 6% kojic acid can be blended in the drug for external use though the amount of the kojic acid which can be blended therein has hitherto been only 2.7%. Thereby a pharmaceutical having a wide range of change in content depending on the dosage form or symptoms is obtained. The amount of the blended maltosylcyclodextrin is preferably 1-5pts.wt. based on 1pt.wt. kojic acid.

Abstract: PURPOSE:To maintain the density of printer at constant level, by providing a voltage applying time regulating circuit for feeding an enable signal of such length as corresponding to an integrated value of thermal head driving voltage fed from an electronic blackboard through a cable, to a thermal head. CONSTITUTION:Thermal head driving voltage V fed from an electronic black board through a cable to a thermal printer is inputted to a monostable multivi brator 2 while being integrated through an integrator.

This signal is inputted to an AND gate 4 where it is ANDed with a thermal head gate signal and outputted as a thermal head enable signal. Since the monostable multivibrator 2 is reset every predetermined time by a reset signal, duration of the enable signal does not exceed a predetermined time. Consequently, printing density is maintained at constant level.
