Title: Method and device for recording on optical disk
Inventor: OTA TAKEO
IPC: G11B7/125
Filed: 1993-06-25
Abstract: PURPOSE:To eliminate an effect of a linear velocity upon recording and erasing performance by equipping the device with a means for detecting the linear velocity of an optical disk and a means for changing high frequency pulse periods of a laser at the time of recording to meet this linear velocity. CONSTITUTION:A signal transduced from light to electricity by a photodetector 2 is led to a focus circuit 3, tracking circuit 4, signal reproducing circuit 5 and rotational synchronization circuit 6. A beam from a semiconductor laser 1 is controlled to be focused on a recording film of the optical disk by the focus circuit 3. Then, the laser beam is controlled to be brought onto a recording track provided on the optical disk by the tracking circuit 4, and a signal from the photodetector 2 is binarized by the signal reproducing circuit 5 with a limiter. After obtaining the sum signal of a gate signal for turning an address signal part into the on-state and the binarized signal from the signal reproducing circuit 5, an address is read out, and a recording data signal is demodulated by a data demodulation circuit 8, and is, afterward, restored to the original recording data by an error correction circuit 14, so that optimum recording pulse duration and setting power can be settled.

Every time when a slit detector unit 28 passes one slit 9, a light emitted from a light-emitting diode 17 enters a photo-transistor 18 through the slit 9, whereby a light detection signal is generated. This light detection signal is demodulated by a filter 27 and the thereafter is inputted to a counter 29. The number of count is stored temporarily in a memory 30 and multiplied in a multiplier circuit 31 by a conversion constant A set in accordance with a measure of a drawing. Then, the result of the multiplication is displayed in a display unit 23.

Title: Measuring method for minute height difference and measuring apparatus thereof
Inventor: KONDO NORIYUKI
IPC: G01B11/22
Filed: 1987-06-22
Abstract: PURPOSE:To measure the depth of a groove accurately by a method wherein a white beam is applied to a sample from the direction vertical substantially to the ample, a regularly reflected beam out of reflected beams from the surface of the sample is intercepted, and a minute height difference of the surface of the sample is measured from the spectrum of the light which is not intercepted. CONSTITUTION:A visible white beam L4 applied from a light source is reflected by the totally reflecting region 42 of a special mirror 40 and applied onto the surface 161 of a sample through an objective lens 12. The beam reflected regularly by the surface 16, passes through the vicinity of the optical axis of the lens 12 and enters the mirror 40. This beam is intercepted by the totally reflecting region 42 and so is not transmitted to the back (the spectroscope 4 side) of the mirror 40. Meanwhile, a diffracted beam which is diffracted by the surface 161 and comes back is distributed widely around the regularly reflected beam as well, and therefore it passes through the mirror 40 and enters an incident pinhole of the spectroscope. This incident beam is turned into a spectrum by a diffraction grating and the spectrum is converted into electric signals by CCD. These signals are subjected to an arithmetic processing to detect a minute height difference therefrom.

Abstract: PURPOSE:To obtain a composite electroplated steel sheet excellent in corrosion resistance, by dispersing fine grains of chromate into a Zn-alloy plating layer applied to a steel sheet and containing Fe, Cr, Mn, Co, Al, Sn, Pb, Mo, and Sb in combination. CONSTITUTION:A Zn-alloy plating layer in which two or more kinds among Fe, Cr, Mn, Co, Al, Sn, Pb, Mo, and Sb are contained in a Zn base is applied to one side of both sides of a steel sheet. At the time of this Zn-alloy plating, the fine grains of chromate and further, if necessary, of one or more kinds among TiO2, ZrO2, Cr2O3, SiO2, and Al2O3 are dispersedly coprecipitated into the plating layer. As the above chromate, PbCrO4, BaCrO4, etc., having limited solubility in a plating bath are suitably used and it is preferable to regulate chromate content in the plating layer to about 0.01-30wt.% based on coating weight. By this method, the Zn-alloy plating layer in which the fine grains of chromate, etc., are uniformly dispersed is formed, and the composite electroplated steel sheet excellent in corrosion resistance can be obtained.

Abstract: PURPOSE:To correct astigmatism by interference of two spherical waves having a ratio in radius of curvature differing by >=1.5 by allowing these waves to intersect with the normals of wave surfaces at such angles at which the prescribed effective grating constant is obtained and forming the grooves of the diffraction gratings to curves of irregular intervals. CONSTITUTION:Two spherical waves having a ratio of radius of curvature differing by >=1.5 interfer by allowing these to intersect with the normal of wave surfaces at such angles at which a prescribed effective grating constant is obtained. Arrangement is so made that when the points of intersections of the normals of the respective spherical waves coincide with the center of the grating surface and when the normals of the grating are made dissident with the bisectors of the angles of intersection of the normals of the spherical waves the plane diffraction grating has the curved grooves of irregular intervals having the same patterns as the interference patterns formed on the grating plane. Thus astigmatisms are corrected.

Abstract: PURPOSE:To prevent the stress of a voice signal from being recognized against the interception of a privacy call signal by sending a privacy call signal being the result of superimposing a transmission voice signal on a noise signal whose power spectrum is nearly flat in all frequency bands and extracting the voice signal from the privacy call signal at the reception side. CONSTITUTION:A transmission noise generating circuit 2 generating a noise signal of periodically the same waveform whose power spectrum is nearly flat in all the frequency band of a transmission voice signal and an adder circuit 3 adding the transmission noise signal and the transmission voice signal of the transmission noise generating circuit 2 are provided to the sender side. On the other hand, a reference noise generating circuit 12 having the same function as the transmission noise generating circuit 2 and an echo canceller 13 extracting the transmission voice signal from the privacy call signal while referencing the reference signal are provided to the reception side. In the addition of signals by the adder circuit 3, it is desired to select a level difference between the level of the transmission voice signal included in the privacy call signal and the level of the noise signal as nearly 20dB. Thus, even if the privacy call signal is intercepted, the content of conversation is not estimated while the stress of the voice is not recognized.
