Abstract: PURPOSE:To make it difficult that signals are affected by the tape running state, by subjecting a color signal and a signal to FM modulation in the high band side and the low band side respectively and multiplexing frequencies to record them and extending the frequency band of the sound signal to raise the dynamic range. CONSTITUTION:A luminance signal 1 is subjected to FM modulation by an FM modulator 2 and is amplified by a recording amplifier 3 and passes a rotary transformer 4 and is recorded on a tape by a recording head 5. A color signal 6 is subjected to FM modulation by an FM modulator 7 and is sent to a mixer 8. An sound signal 9 is subjected to FM modulation by an FM modulator 10 and is sent to the mixer 8 and is mixed with said color signal. The output signal is amplified by a recording amplifier 11 and passes a transformer 12 and is recorded on a tape by a recording head. Frequencies of the color signal and the FM modulation signal are arranged in the high band side, and the frequency of the sound signal is arranged in the low band side, and frequencies of both signals are multiplexed. At a demodulation time, reproduced RF signal is separated into frequencies and they are demodulated respectively to take out the color signal and the sound signal easily.

Filed: 1986-05-21
Abstract: PURPOSE:To improve the reading accuracy of a mask alignment displacement to twice without contracting the diameter of a beam spot by so forming main and sub scale patterns that the width difference of square patterns corresponding to the main and sub scale patterns has a part that A and A+  are alternately repeated in a pattern arranging direction and the displacement of the center lines of the corresponding square patterns is sequentially different by 1/2 of the in the pattern arranging direction. CONSTITUTION:When the difference of the pattern width between the main scale square pattern of a pattern width W' in a main scale pattern and a sub- scale square pattern (pattern width w) corresponding to the main scale pattern is represented by A in a vernier pattern, the difference of the pattern width of the main scale square pattern of the pattern width W in the main scale pattern and the sub-scale square pattern (pattern width W) corresponding to the main scale pattern is A+ ( =0.1mum), and the displacements of the square patterns of each set at the center lines are sequentially different at  /2(=0.05mum) unit. The degree of the positional displacement at 0.05mum unit is detected to read out the mask alignment accuracy at 0.05mum unit, thereby improving the reading accuracy to twice as large as the conventional one.

Abstract: PURPOSE: To obtain the tuned amplifier adjusting optionally a tuning frequency and a maximum attenuation without interference by adopting two phase shift circuits and a feedback circuit so as to make the gain of the entire system to be unity thereby making the total sum of phase differences of a closed circuit to be zero. CONSTITUTION: Since a voltage VL1 across an inductor 17 crosses with a voltage VR1 across a variable resistor 14 at right angles on the circumference on the vector diagram, the phase difference between the input voltage applied to the gate of a FET 12 and the voltage VL1 changes from 90 deg. to 0 deg. according to a change in a frequency ω from 0 to ∞. The phase shift ϕ1 of a phase circuit 10 as a whole is twice the phase difference and changes from 180 deg. to 0 deg. according to the frequency change. The phase shift circuit 30 also undergoes a phase shift to the opposite phase input voltage. The tuning amplifier 1 undergoes a phase shift by the two phase shift circuits 10, 30 to have a phase shift of a sum of 0 deg. at a prescribed frequency.  The gain of the amplifier 1 is made almost equal to unity by adding the input signal and the output signal of a noninverting circuit 50 which carries out amplification at a prescribed amplification factor without phase change of the output signal, at a prescribed rate.

Title: Defect detection method
Inventor: KAMATA TERUMI
IPC: G01N21/94
Filed: 1998-04-13
Abstract: PROBLEM TO BE SOLVED: To provide a defect detection method that can detect a wavy defect being extended in a plurality of directions of an object to be inspected without complicating the configuration of a detection device. SOLUTION: The image of an object to be inspected changed into two-dimensional image data by a two-dimensional CCD or the like, and the two-dimensional image is scanned in a slanting direction, thus detecting a lengthwise and crosswise wavy defect simultaneously by common algorithm. At this time, the two-dimensional image data are slantingly scanned in the zigzag shape as in a picture drawn with a single stroke of a brush, thus detecting the defect without being affected by a gray level with a large period where the entire region of the two-dimensional image data is affected. Also, the data are complemented to the end part of the two-dimensional image data, thus absorbing the steep fluctuation of a signal, fixing the appearance cycle of the defect, and hence improving detection accuracy.  Also, the region of the two-dimensional image data is divided into blocks with a small region so that the length of a one-dimensional luminance signal being read at each scan is set to the approximately shortest length of the wavy defect, thus improving defect detection accuracy to the short wavy detect being generated only at one part of the entire region.
