Filed: 1988-12-06
Abstract: PURPOSE:To obtain same image quality even in a long-time recording and reproducing mode as that in an ordinary recoding and repoducing mode by specifying the width of a magnetic head loaded on an actuator. CONSTITUTION:The width of the magnetic head 2b for the long-time recording and reproducing mode is set 1 - 1.5 times as wide as that of a recording track at the time of the long-time recording and reproducing mode.

Title: Partial discharge measuring method
Inventor: ENDO TAKESHI
IPC: G01R31/12
Filed: 1989-11-29
Abstract: PURPOSE:To obtain high detection sensitivity by selecting a measurement frequency at which an SN ratio becomes as high as possible by calibrating the detection sensitivity with calibration pulses and measuring partial discharging pulses at the frequency. CONSTITUTION:A coupling capacitor 3 and detection impedance 4 are connected between a high voltage conductor connected to a high voltage application terminal 2 and the ground and a measuring instrument 5 is connected in parallel to the detection impedance 4. The frequency spectrum of a detection signal is found by this circuit while no electricity is applied to the cable 1 and a pulse generator 6 is not in operation, namely, in a state wherein only noises are present. Then the pulse generator 6 is put in operation and calibration pulses of 100pC are applied from the pulse generator 6. In this state, the frequency dependency of the detection pulses is found by using the spectrum analyzer of the measuring instrument 5. Those two cases are compared with each other to know that noises are reduced greatly between 4.5 and 5.5MHz and the SN ratio becomes high between 4.8 and 10MHz eventually.

Title: Method for correcting and deciding coordinates of objective point on wafer
Inventor: ATSUTA HITOSHI
IPC: H01L21/68
Filed: 1997-10-23
Abstract: PROBLEM TO BE SOLVED: To correct or decide the coordinates of an objective point on a wafer by taking into consideration the positional deviation caused by the deformation of a stage. SOLUTION: Coordinate correction information indicating the relation, between actually measured stage coordinate values containing positional deviation components derived from the deformation of a stage and ideal stage coordinate values containing no positional deviation component, is found on a plurality of coordinate correcting reference points set on a wafer WF0 for correcting coordinates placed on the stage. Then, a plurality of measuring points PM1-PM15 are set on a reference wafer WF1 for setting measuring point. At the time of setting the points PM1-PM15, the stage coordinate values of the points PM1-PM15 are also measured. The actually measured stage coordinate values are corrected, based on the coordinate correction information and changed to wafer coordinate values through coordinate transformation.  When measurement is performed on a wafer WF2 to be measured, corrected stage coordinate values containing the positional deviation components derived from the deformation of the stage are found by performing coordinate transformation on the wafer coordinate values of the points PM1-PM15, and by correcting the coordinate-transformed wafer coordinate values based on the coordinate correction information.
