Abstract:
A method and an apparatus for producing a stamper capable of producing in a high yield a stamper for producing a high quality optical disk. According to the conventional production technology of stampers, primary tin ions in a sensitizer containing the tin ions used for electric conduction treatment of a substrate surface are readily oxidized by dissolved oxygen and cause defects during the production of stampers. Therefore, even when a production apparatus is automated, substantially daily maintenance is necessary so as to keep satisfactory yield. The present invention carries out the electric conduction treatment of the substrate surface by treating the substrate surface by a treating solution containing a compound having a betaine structure and a polyoxyethylenealkylamine compound, then treating it by a colloidal solution containing tin and palladium and further conducting electroless plating. In this way, the present invention makes the maintenance work easier in an automated process and makes it possible to produce a high quality stamper with a high production yield.
Abstract:
Haarbehandlungsverfahren, aufweisend das Einwickeln gebundenen Haares mit einem Haarwärmgerät in Folienform mit mindestens einem Heizteil, während mindestens der Teil des Haares nahe der Wurzeln nicht eingewickelt wird, um das Haar zu wärmen, wobei das Haarwärmgerät in Folienform mindestens ein Heizteil in dessen Mitte und einen Rand um das Heizteil aufweist, das so gestaltet ist, dass es gebundenes Haar in dem Heizteil einwickelt und am Platz gehalten wird, um den eingewickelten Zustand zu erhalten, indem der Rand mittels eines Befestigungsmittels, wie zum Beispiel eines elastischen Bands, einer Schnur oder eines Drahts, befestigt wird, die Breite des Rands 3 bis 15 cm über den gesamten Umfang des Heizteils ist, wobei das Haarbehandlungsverfahren aufweist Aufbringen eines Haarbehandlungspräparats, das mindestens eine ölige Verbindung und eine organische Säure enthält, auf das einzuwickelnde Haar, wobei die ölige Verbindung ausgewählt ist aus der Gruppe enthaltend: höhere Alkohole mit einer geradkettigen Alkylgruppe, enthaltend 14 bis 22 Kohlenstoffatome, Esteröle, Kohlenwasserstofföle, natürliche und synthetische Wachse und Öle in erster Linie aus Triglyceriden, und Behandeln des Haars durch Einwickeln des zu einem Knoten gebundenen Haares mit der Mitte des Haarwärmgeräts in Folienform, und Wärmen des Haares derart, dass die Enden des Haares dieses Abschnitts völlig in den eingeschlossenen Raum, der durch das befestigte Haarwärmgerät gebildet wird, gesteckt werden.
