Title: Apparatus for measuring characteristics of magnetic disc medium
Inventor: TAZAKI YOSHIYUKI
IPC: G01R33/12
Filed: 1986-02-14
Abstract: PURPOSE:To obtain an accurate overlight value, by reading LF (lowest frequency in writing into medium) contained in a lead terminal to be converted into a decibel value. CONSTITUTION:A lead signal from a magnetic disc is turned to a BPF signal (s) through a terminal 10a and a BPF 101 to be inputted into a non-inversion input terminal of a comparator 2. An output signal (c) of the comparator 2 is turned to an LBF output signal (a) through an LPF 3 to be inputted into an inversion input terminal of the comparator 2. While the signal (a) is larger than the signal (s), from the output signal (c) of the comparator 2, a frequency component is eliminated with an integrating action of the LPF 3 and the signal (c) is turned to a signal (a) indicating the size of an LF component contained in the lead signal (e). The signal (a) is inputted into an A/D converter section 6 through a switching section 5 to generate a digital signal (d) by a conversion start signal (r) from a central control section 7. The signal (d) undergoes a calculation processing at the control section 7 thereby assuring a highly accurate overlight value by a decibel value.

Filed: 1983-02-25
Abstract: PURPOSE:To hold the first field caught electromagnetically, irrespective of any changeover of the observation mode, by providing a means for a signal in order to compensate for the movement of field caused by changeover of observation mode. CONSTITUTION:During observation of a certain field, when it is required to observe the same field through the transmitting electron microscope image, a signal which commands observation of transmitting image is supplied to an observation mode selection control circuit 21 by means of the observation mode selection button 25b of an input device 25. As a result, the circuit 21 selects the connection of a first selection circuit 17 as indicated by a solid line in the figure. Therefore, a signal sent from a deflection signal generator 19 is supplied to a scanning deflection coils 7a, 7b through a second signal converter 2 and simultaneously it is also supplied to a deflection power supply 15 through a first signal converter 18. Since the signal to be supplied to the deflection power supply 15 is converted so that the field which is the same as the field in the scanning image observation mode can be obtained by the first signal converter 18, the transmitting image in the same field as that in the scanning image observation mode can be obtained on a phosphor plate 26.

Filed: 1997-02-17
Abstract: PROBLEM TO BE SOLVED: To provide a method and apparatus which enable fast and easily adjustable measurement of dimensions of the outer diameter, the inner diameter and the eccentricity of a cylindrical object based on images at a low cost of the apparatus. SOLUTION: The degree of displacement of an edge part of the inner circumference 2 of an cylindrical object from a reference position is measured based on images by an image processor 8 at two points almost facing each other over the entire inner circumference thereof and the dimensions of the outer diameter, the inner diameter and the eccentricity of the object are calculated by a fixed expression only from the degree of displacement. A means for photographing the two inner circumferential edge parts over the entire inner circumference thereof is constituted of a rotary drive mechanism 6 which rotates the cylindrical object at a home position contacting a V groove of a mount base 5 by which the outer circumference of the cylindrical object 1 is determined and a line sensor camera 7.  This accomplishes the measurement of dimensions by one image pickup means and one image measurement means to simplify the structure of the apparatus thereby speeding up the dimensional measurement at a lower cost. Thus, this single arrangement of the image pickup means facilitates adjustment and calibration for maintaining accuracy in the positioning of a photographing line 3, the focus and magnification in photographing and the like.

Abstract: PURPOSE: To reduce electric power consumption by conducting electricity only to the  necessary circits through switches responding to the respective strokes of a release button, and generating a magnetic force offsetting magnetic flux thereby releasing the  detention by a permenant magnet.  
     CONSTITUTION: When a shutter button 347 is depressed to the 1st stroke in a shutter  second time priority state, a switch S 1  goes on to conduct electricity only to the photometric arithmetic circuit and a capacitor for photometry is charged with a photodetector P in accordance with subject luminance. Further when the button 347 is depressed  and a switch S 2  closes in the 2nd stroke position, electricity is supplied to a control  circuit, a malfunction preventing circuit, etc., and pulses are supplied to the coil of a  permanent magnet M 1 , then the attraction force of the magnet M 1  is annihilated by  the offsetting magnetic force and the detention of an attracting lever 330 is released,  whereby the aperture is controlled in accordance with the subject luminance. The same holds true of a permanent magnet M 2  for shutter, thus the shutter second priority  automatic exposure controlling is accomplished. The similar operations take place in  the case of aperature priority, etc., as well and the automatic exposure device of reduced electric power consumption is obtained.

Abstract: PURPOSE:To prevent data omission and double reception of data by receiving only a frame of multiple address communication for securing a receiving buffer after a specific frame is received unconditionally and inhibiting the reception of the frame of multiple address communication after the reception. CONSTITUTION:When a data transmitter transfers a frame to all data transmitters, a processor 33 transmits a command frame for setting busy FFs and reception inhibition FFs in all the transmitters to all stations. When a signal is generated on an FCSOK signal line 202, a busy FF123 and a reception inhibition FF124 are set, and if a frame addressed to this station except multiple address communication is received during said period, a frame receive signal line 203 turns on and an all-station address signal line 204 turns off to generate a signal on the FSCOK signal line 202, setting a busy transmission request FF125. A busy frame is sent out to a signal line 207 and converted into a signal, which is returned to the transmitting origin. When a target frame arrives, a signal is generated on the FCSOk signal line 202. When the buffer busy signal 205 of a receiving circuit 102 is on, the FF125 is set.
