Title: Film thickness measuring apparatus using specimen rotation type interference method
Inventor: MATSUDA JOJI
IPC: G01B11/06
Filed: 1986-09-26
Abstract: PURPOSE:To easily measure the thickness of a membrane with high accuracy in a non-contact manner, by irradiating a body to be measured with laser beam at a predetermined angle and measuring the intensity of an interference fringe of the reflected light from the surface of said body to be measured and the light obtained by reflecting the transmitted light through the body to be measured while changing the incident angle of the body to be measured while changing the incident angle of the laser beam. CONSTITUTION:When laser beam is incident to a membrane 10 to be measured having a refractive index (n) and a thickness (h) at an angle theta, reflected beam having intensity IA is sent out from the front surface of the membrane 10 and reflected beam having intensity IB is sent out from the back surface thereof. When the beam path difference between the reflected beams from the front and back surfaces of the membrane 10 is set to (d), said beam path difference is shown by d=2h(n<2>-Sin<2>theta)<1/2>. In this case, when lambda is set to a wavelength and A, B are set to a constant, the intensity of interference beam is shown by I=A+ Bcos(2pid/lambda). Further, when beam path lengths are respectively set to d1, d2 at the time of incident angles theta1, theta2, the positions where the intensity of an interference fringe becomes the max. value and the min. value are given by d1-d2=(1/2)mlambda (wherein m is an integer). Therefore, the thickness (h) of the membrane is shown by formula. When the wavelengths lambda1, lambda2 and incident angles theta1, theta2 of incident beam having a refractive index (n) are given, the thickness (h) of the membrane 10 to be measured is calculated.

IPC: G11B7/0045
Filed: 1983-12-02
Abstract: PURPOSE:To improve the error rate after demodulation without decelerating the data transfer speed by using the reflected light produced by the recording light to detect assuredly a drop-out during the recording of information and processing the defective record. CONSTITUTION:A focus error signal b' whose gain is controlled in response to the reflected ligh quantity given from an optical record disk 2 and a tracking error signal c' are supplied to a drop-out detecting circuit 41 and 42 respectively and compared with a reference level to be delivered and turned into pulses. The drop-out inspection parts 49 and 50 count the width, number, etc. of drop-outs in a recording mode and send these count data to a controller 21. The controller 21 inhibits the transmission of a record gate signal (e) to a digital modulation part 51 when it decides the presence of such a drop-out with which the incapability is expected for error correction when an information recording area which is under a record mode is demodulated. Instead the controller 21 sends a record gate signal (f) to a discriminating signal generator 52 and performs control so as to record to the defective record discriminating signal at the last part of the information recording area.

Abstract: PURPOSE:To produce high-purity antimony with a simple operation by distilling an aq. antimony chloride soln. in a specific temp. range and charging dropwise the distillate thereof to hydrogen gaseous flow kept at a specific temp. CONSTITUTION:The aq. antimony chloride soln. obtd. by dissolving antimony oxide with a hydrochloric acid is heated and distillated by using an ordinary distillation apparatus and the water, hydrochloric acid and low boiling component are evaporated at about 100-110 deg.C for the beginning. The apparatus is replaced with a receiving vessel contg. a small amt. of ionized water and the distillate is received therein when the temp. rises sharply to about 200 deg.C. The distillation is completed when there is no more soln. on progressing of the distillation and the temp. begins to rise to >=230 deg.C. A small amt. of the ionized water is added to the distillate (SbCl3), if necessary, to prepare an aq. soln. which is then charged to the gaseous hydrogen flow kept at >=800 deg.C, more preferably about 900 deg.C at each slight amt. to the extent of dropping, by which reduction is executed. The high-purity antimony of about 99.999 class grade is thus obtd. efficiently by a simple operation.

Abstract: PURPOSE: To enable miniatuarizing a device and also to facilitate the reproduction of a clock by transferring carrier wave with different on-period length at every prescribed time in accordance with a data kind. CONSTITUTION: A signal to be received is an ASK modulation signal being different in time while carrier wave is on when data is 'one' and 'zero'.

A waveform reshaping circuit 205 converts the envelope into a CMOS logic signal and the waveform-reshaped signal is outputted to a control circuit as a data clock and also used as the clear signal of the counters 206 and 207. A206 sets FF208 by a pulse outputted after counting a prescribed number and b207 clears FF208 by another pulse outputted after counting the prescribed number. That is, time while carrier wave is on is counted so that is it judged whether data is 'one' or 'zero'.
