Title: Attitude control device for rotating shaft of magnetic bearing type turbo-molecular pump
Inventor: YAMAMOTO MASAYUKI
IPC: F04D19/04
Filed: 1986-07-07
Abstract: PURPOSE:To certainly control and prevent vibration on the side of a stator by removing the frequency component of the number of revolutions from a detecting signal for the radial position of a rotating shaft used for controlling the attitude of the rotating shaft rotating in its magnetically floating state. CONSTITUTION:The position of a rotor 12 is detected by an axial position sensor 30 and radial position sensors 32, 34, and the number of revolutions is detected by a sensor 36 for the number of revolutions, and thereby one pulse signal is made to occur per revolution. Detecting signals from said radial position sensors 32, 34 are supplied to the one comparison input side of a comparator 40, and a signal corresponding to the reference position of a rotating shaft is supplied from a reference position setting device 42 to the other comparison input side of said comparator 40. Therefore, the rotor 12 is moved and controlled in the direction which makes its position detected by the sensor 32 coincide with its reference position. In addition to that, since a band elimination filter 20 removes the frequency component of the number of revolutions from a signal issued by said sensor 32, vibration on the side of a stator 16 can be prevented even when the rotor 12 fluctuates in the number of revolutions.

Title: Magnetic disc device
Inventor: KUBO MASAHIRO
IPC: G11B33/10
Filed: 1985-07-19
Abstract: PURPOSE:To execute the highly accurate control of the extent of floating of a slider block when assemblying by providing a mirror part for reference. CONSTITUTION:At the outside of the projected strings 15 and 17 of a slider block 12, the mirror parts 21 and 22 for reference are formed from a sliding plane K with the distance of a minute step S to the opposite direction from the disc. The minute step S is a value in a range from 0.1mum-2mum, for instance at 0.1mum. The rays of light are irradiated from a light source device 35, and when the bottom surface of the slider 6 is observed through a microscope 37, interference fringes A are observed at the mirror parts 21 and 22. In this case, because the parts 21 and 22 are distant from the plane K by the minute step S, the said interference fringes A can at all time by observed at the parts 21 and 22 even if the floating extent of the slider 6 is <=0.1mum. Therefore, by using this interference fringes A, the clearance between a pseudo magnetic disc plate 32 and the mirror parts 21 and 22 can be obtained.

Title: Seizing signal detection device
Inventor: SUGA SEIICHI
IPC: H04M7/00
Filed: 1998-06-08
Abstract: PROBLEM TO BE SOLVED: To detect a seizing signal with the threshold of a level that is selected based on maximum reference value as detection reference by obtaining a seizing signal when the seizing signal from an analog exchange can not be detected any more as the maximum reference voltage. SOLUTION: A storage circuit 6 holds an initial value and sets a threshold switch circuit 5 to threshold as the initial value. A comparator 4 compares voltage value inputted from a current/voltage conversion circuit 2 with comparison voltage that corresponds to threshold given from the circuit 5 and detects a seizing signal. When information that detects the seizing signal based on a seizing signal detection result 9 transmitted from the comparator 4 is received, the value of the circuit 6 is set to the second largest value and comparison voltage of the comparator 4 is increased. When the seizing signal is detected based on the result 9 in this way, a control circuit 7 sequentially increases the comparison voltage of the comparator 4 and increases the comparison voltage until the seizing signal can not be detected any more.  Then, the circuit 7 can obtain maximum reference voltage at the time of receiving the seizing signal.
