Abstract: The present invention provides an internally-toothed member of reduced size and enhanced quality, durability and productivity in manufacture. This internally-toothed member has a first cylinder portion and a second cylinder portion which is larger in diameter than the first cylinder portion. First and second internal teeth are formed to protrude radially inwardly from inner peripheral surfaces of the first and second cylinder portions respectively.

Because the area between the second internal teeth and a concave portion and the concave portion itself do not decrease in thickness during formation of the second internal teeth, it is possible to prevent cracking and to thereby enhance durability of the internally-toothed member.

Abstract: A tapping mode atomic force microscope includes a sinusoidal signal generator. The sinusoidal signal generator generates sinusoidal wave signals to a modulating laser diode for outputting a pulsed laser beam. The laser beam reflects from the back side of a photo detector and then a current signal with a corresponding intensity is output b y the photo detector. Then, the signal is converted by a current to voltage converter and then is operated by a differential amplifier. After the DC component and the undesired multiple frequency harmonics of the current signal is filtered by a band pass filter, the current signal is processed by a demodulation circuit and a low pass filter to produce a voltage value corresponding to probe deformation. After inputting this voltage value to a Z-axis servo controller, a corresponding control command is acquired based on a control algorithm so as to keep the value of the probe deformation constant.
