    • A hair relaxer includes at least one specific mercapto compound such as 2-methoxyethyl 3-mercaptopropionate, 2-mercapto-4-butanolide and 2-mercapto-4-butyrolactam. The hair relaxer can achieve an excellent effect of shaping and relaxing hair over a wide range of pH values from weak acidity to weak alkalinity. In particular, the hair relaxer displays a more superior hair shaping and relaxing performance in a weakly acidic to neutral pH range. Consequently, the hair relaxer can drastically reduce the damage to the hair and skin and can reliably perform straightening, uncurling, curling and other hair processing.
    • 头发松弛剂包括至少一种特定的巯基化合物,例如3-巯基丙酸2-甲氧基乙酯,2-巯基-4-丁醇酯和2-巯基-4-丁内酰胺。 头发松弛剂可以在从弱酸性到弱碱性的广泛pH值范围内实现成型和松弛头发的优异效果。 特别地,头发松弛剂在弱酸性至中性pH范围内显示出更优异的头发成型和松弛性能。 因此,头发松弛剂可以大大降低对头发和皮肤的损伤,并可以可靠地进行矫直,卷曲,卷曲和其它头发处理。

    • The invention makes it possible to drive a halftone image device and achieve high halftone reproduction by allowing at least one of the leading and trailing edges of a pulse width-modulated signal applied to a recording head, or forming amplitude- and width-modulated pulses, respectively, as driving pulses for placing one dot under halftone control, and changing pulse width modulation in a stepwise manner, using the pulse width of the amplitude-modulated pulse as a unit pulse width. The invention intends to achieve high-voltage and high-speed pulse output and low power consumption by converting input data such as halftone image data to a voltage signal, superposing pulse voltages of opposite polarities and applying the resulting signal to a switching circuit constituting an output state in the form of a switching signal, and also makes it possible to achieve high speed and high-voltage driving by connecting at least one of equivalent two-terminal elements in series to at least one of the respective driving elements of a complementary FET driving circuit, said equivalent two-terminal elements are each turned on with a current of a certain or higher value passing therethrough to show constant-voltage characteristics and turned off with a current of a certain or lower value passing therethrough to become a constant resistance.
