    • A dial type switch mechanism is developed in which an installation space can be made as small as possible. In a dial type switch mechanism (10) furnished with a push type switch part provided in its center, and a dial switch part which operates a dial fitted around the push type switch part, there are provided: a substantially cylindrical dial knob (21), in the center of which a cavity is provided for the push type switch part to be installed; a ring-shaped joint ring (23), which is supported such that it can rotate freely relative to a front panel (6) and connects and rotates together with the dial knob (21); and a rotary bracket (24), which is joined to the joint ring (23), and in which a switch rotation shaft (24b) that operates the dial type switch part is connected together with a ring-shaped member (24a) via an arm (24c).

    • A system or kit for analysis of phosphatase comprising a reagent I containing NADP or NADPH as a main component, and a reagent II containing components for color-development signal amplification utilizing NAD-NADH interconversion, wherein at least one of the hydrogen donors participating in the NAD-NADH interconversion is included in reagent I, but not in reagent II, which eliminates the necessity that the reagent II is further separated into two parts. This enables the preparation of reagent II as a mixture which can be readily used and which can be preserved for a long period of time without "reagent blank" occurring. Additionally, the present kit eliminates the necessity of mixing reagents I and II immediately before actual use and thus permits periodical analysis of samples with a reagent having the same components for long time periods with reliable and uniform sensitivity.
    • 一种用于分析磷酸酶的系统或试剂盒,其包含含有NADP或NADPH作为主要成分的试剂I和含有利用NAD-NADH相互转化的显色信号扩增成分的试剂II,其中至少一个氢供体参与 NAD-NADH相互转化包括在试剂I中,但不包括在试剂II中,这不需要将试剂II进一步分成两部分。 这使得可以制备试剂II作为混合物,其可以容易地使用并且可以长时间保存而没有发生“试剂空白”。 另外,本试剂盒消除了在实际使用之前混合试剂I和II的必要性,因此允许用具有相同组分的试剂在长时间段内具有可靠和均匀的灵敏度的定期分析。
