Title: Disturbance information reproducing device
Inventor: HAYASHI YASUHIRO
IPC: G11B7/09
Filed: 1984-09-29
Abstract: PURPOSE:To reproduce a disc stably by distinguishing flaws of the disc and external oscillation from each other and switching the characteristic of tracking servo to characteristics adapted to respective cases. CONSTITUTION:The addition signal of a 4-divided detector is subjected to waveform shaping and envelope detection by a waveform shaping circuit 35 and an envelope detecting circuit 37 respectively and is inputted to a comparing circuit 38. The circuit 37 inputs a pulse to a monostable multivibrator 42 when detecting that the envelope detection output is lower than a certain level. Then, a pulse is outputted from the monostable multivibrator 42 to open an analog switch 46, and the gain of a variable gain amplifier 44 is reduced. Meanwhile, signals of beam detectors 30 and 31 are added by an adder 39, and the result is inputted to a signal comparing circuit 41 through an LPF40. The circuit 41 inputs a pulse to the reset terminal of the monostable multivibrator 42 when detecting that the output of the LPF40 is lower than a certain level because of flaws o the disc. By this constitution, the gain of the amplifier 44 is raised in case of only oscillation and is reduced in the normal case to make track jump difficult for flaws on the disc.

Abstract: PURPOSE:To simplify the structure of a scanning electron microscope by using the combination of a set of bands and a set of pulleys to perform the rotation, the X-direction movement and the sending of the sample. CONSTITUTION:When a sample-rotating stage 12 is returned to the sample change position by rotating driving knobs 18a and 18b clockwise, the groove 25 of a shaft 23 and the groove of a lock base 19 are attached to each other. Next, when a handle 27 is rotated by 90 deg. before being moved from a guide groove 26b to a guide groove 26a and is then rotated back by 90 deg., the lock base 19 is detached from the sample-rotating stage 12 and attached to a sample chamber hole 14 thereby being airtightly sealed. As a result, the part on which a sample 20 is placed is separated from the sample chamber through a vacuum. Next, after a lid 13 is removed before the sample 20 is attached to the lock base 19, the lid 13 is again placed over the sample chamber which is then exhausted through an auxiliary exhaust hole until a given vacuum degree is produced. After that, a procedure reverse to the above procedure is performed so as to move the lock base 19 to the observation position. The visual field selection and rotation of Y direction can be performed with a Y driving screw 21 and those of X direction can be performed with the driving knobs 18a and 18b.
