Title: Method and device for dry etching of silicon nitride film
Inventor: HAYASAKA NOBUO
IPC: H01L21/302
Filed: 1987-10-15
Abstract: PURPOSE:To increase the ratio of etching selection of a silicon nitride film to a silicon oxide film by employing an element F and the like as a gas to etch the silicon nitride film and introducing at least the element F as a radical into a vessel which houses a substrate to be processed. CONSTITUTION:In selectively etching a silicon nitride film 44 with respect to a silicon oxide film 43, a gas which involves an element F and other halogen elements is introduced into a vessel which houses therein a substrate to be processed, on the surface of which the silicon nitride film 44 and the silicon oxide film 43 are formed. Thereupon, at least the element F is excited at the other area and introduced into the vessel as active species while the substrate 41 is irradiated with a light from an excimer laser or the like. Hereby, the light excites the surface of the substrate 49 to promote the etching reaction. Thus, there are improved the etching speed of the silicon nitride film 44 and the selection ratio of the silicon nitride film to the silicon oxide film 43.

Abstract: PURPOSE:To contrive miniaturization and less power consumption of the subject device by winding a magnetic tape around a rotary drum at a wrapping angle for scanning only one part of a track formed in a prescribed format and performing recording and reproducing accordingly. CONSTITUTION:A rotary head device 1 is provided with one pair of magnetic heads Ha and Hb at a disposing angle of 180 deg..

Title: Ultrasonic flaw detector
Inventor: ENDO TOMIO
IPC: G01N29/22
Filed: 1995-10-05
Abstract: PROBLEM TO BE SOLVED: To accurately identify the internal defect of a sample without being affected by the characteristics of a transducer by detecting the presence/absence of the internal defect by comparing the positive and negative values of reflected wave signals with each other. SOLUTION: An ultrasonic transducer 12 converts the impulse signal of a transmitting section 11 into an ultrasonic wave and radiates the wave upon a sample 1. The transducer 12 converts reflected waves from the front and rear surfaces and inside of the sample 16 into reflected wave signals and a gate section 18 only extracts the internally reflected wave signal for identifying defect. When the sample 16 has no internal defect, the peak value of the reflected wave signals becomes negative > positive and the signals do not pass through an HPF 20 and are halved by means of a switch 21. One half of the signals is detected 22, sent to a comparing section 25, and stored in a memory 28 as picture data. The other half is detected 24 after polarity inversion 23 and sent to the comparing section 25. The signal of the compared result becomes off.  When the sample 16 has an internal defect, the peak value becomes positive > negative and the signals pass through the HPF 20. The compared result of the signal becomes on. The on/off of the signals are displayed 30 as defect identifying data together with the picture data.

Title: Position detection device
Inventor: NAKAZATO MASAKAZU
IPC: G01D5/244
Filed: 1990-09-28
Abstract: PURPOSE:To enable a stable position detection with an improved accuracy to be performed by performing correction and adjustment of the center of signal wave for equalizing the amplitude level of a sensor signal for each pitch of a magnetic scale. CONSTITUTION:A peak value of output signal of a sensor 52 is updated and stored in a memory for each pitch and an inverse number of the difference between the peak value and the central value of a signal wave at each pitch is obtained as a normalized coefficient. By multiplying an output of the actual sensor 52 by this normalization coefficient, the output of the sensor 52 is corrected for each pitch of a magnetic scale 51, thus enabling each amplitude level to be equalized. Thus, a rough position and an accurate position are calculated by the normalized two-phase signal and these are added for calculating a position signal, thus enabling output fluctuation due to scattering etc. of a magnetic scale 51 to be compensated for and a position signal with improved accuracy to be output.

Abstract: PURPOSE:To perform low-loss coupling by mixing light beams from two linear polarized light source having the same wavelength by a polarization beam splitter and then supplying the obtained light for excitation and signal light to be amplified directly to a wavelength multiplexer. CONSTITUTION:The light beams from 1st and 2nd semiconductor laser diode modules 11 and 12 are so set as to become a P wave and an S wave on the boundary surface 17 of the polarization beam splitter block 15, and the both are polarization-mixed and outputted as the exciting light.
