Inventor: GEERII TORENTO EGUBAATO
IPC: G11B19/04
Filed: 1993-04-13
Abstract: PURPOSE: To enable a head floating quantity to be measured digitally by forming and storing a spacing signal for indicating the quantity in response to a signal corresponding to the higher harmonic of the floating quantity signal read out from a disk surface. CONSTITUTION: An electronic circuit 24 for reading data channel 20 forms higher harmonic signals corresponding to the higher harmonics of a floating quantity signal that is read out from a disk surface in response to the rotation of the rigid disk 15, transmitting it to the clearance and slip program part 33 of a servo processor 30 using a signal path 56. The clearance and slip program part 33 forms a spacing signal indicating the floating quantity of a head 13 at plural positions on the disk 15 face in response to the higher harmonic signal, storing it in the predicted fracture analysis(PFA) storing part 45 of a file microprocessor 40. Accordingly, it is possible that the floating quantity of the head 13 since the manufacture is digitally measured, held as history and referred to selectively.

Title: Method and device for placing spacecraft in intended orbit
Inventor: KOPPEL CHRISTOPHE
IPC: B64G1/26
Filed: 1997-04-04
Abstract: PROBLEM TO BE SOLVED: To place a spacecraft in an orbit different from the orbit in which the spacecraft is generally operated by constantly controlling perigee altitude and apogee altitude independently in a prescribed direction until the apogee altitude, the perigee altitude and the orbit inclination of intermediary orbit of the spacecraft substantially coincide with the values of an intended orbit. SOLUTION: When the apogee altitude of intermediary orbit is sufficiently high, for example, in a position 104G, a thruster device corrects only the relative control of steering of total thrust while continuing the operation, whereby the inclination is changed. While an artificial satellite is moved in a part 104K of a spiral orbit, the thruster device continues operating, and corrects only the total thrust so that the spiral orbit passes the apogee on each turn, or the apogee in each intermediary orbit while enhancing the perigee altitude. When a desired inclination change is provided in a position 104N, the thruster device continues operating to conform the thrust to the orbit plane. Thus, the thruster is once operated, whereby the orbit can be transferred from the initial orbit to the final intended orbit.

Abstract: PURPOSE:To prevent sputtering to a material to be processed and contamination and to perform uniform processing by providing a region for relaxing vibration of a plasma between plasma generating means for generating a helicon wave plasma and electron accelerating means for drawing electrons from the generated plasma. CONSTITUTION:A plasma is efficiently generated by a helicon wave excited by a discharge tube 18, and its vibration is attenuated as it is propagated through a relaxation region 21.
