    摘要: The present disclosure provides siloxane derivatives of amino acids that have surface-active properties. The amino acid can be naturally-occurring or synthetic, or they may be obtained via a ring-opening reaction of a lactam, such as caprolactam. The amino acid may be functionalized with a siloxane group to form a compound that is surface-active and has surfactant characteristics. The compounds have low critical micelle concentrations (CMC) as well as the ability to lower the surface tension of a liquid.

    摘要: A position detection device includes a position sensor including a coil and a magnetic core, and a signal processor. The signal processor generates a rectangular wave voltage applied to the coil, converts a current which flow through the coil by the rectangular wave voltage into a voltage and outputs the voltage, and acquires a voltage measurement value obtained by sampling the output voltage after predetermined time in synchronization with a timing of rising or falling of a waveform of the rectangular wave voltage. The predetermined time is set such that the voltage measurement value is restricted within a range of 40% or more and 99.999% or less with respect to a maximum value of the rectangular wave voltage when the coil is at a position where an inductance of the coil is minimum.

    摘要: A cable bushing includes a frame having at least one space for receiving at least one resilient cable grommet, and which has at least one first and one second frame part, as well as a clamping lever which may be rotatably movably connected to the first frame part and is movable between an open position and a closed position. The frame parts are braced against one another in a bracing direction in the closed position of the clamping lever.
