Title: Etching process of thin film
Inventor: KAKIUCHI KOJI
IPC: H01L21/3065
Filed: 1990-08-18
Abstract: PURPOSE:To avoid any residual etching process by a method wherein the over- etching time is set up conforming to the fluctuation time of etching light intensity wave form near the etching terminal point using the value proportional to this fluctuation time. CONSTITUTION:The overetching time is set up conforming to the fluctuation time of etching light wave form near the etching terminal using the value proportional to this fluctuation time. When an aluminum thin film 6500Angstrom  is etched away using a parallel-plate type plasma etching device, the linear differential of observed wave form is simultaneously counted to decide the wave form and then the quardratic differential value is further counted to decide the wave form. At this time, -0.5V is set up as the threshold value so as to assume the points not exceeding the threshold value as the wave form fluctuation time. Next, the etching terminal point is set up while the time detecting this point shall be stored in a storage. Finally, the time difference is counted to be set up as the wave form fluctuation time.

Title: Mode eigenvalue measuring method
Inventor: OTA KAZUHIKO
IPC: G01S7/526
Filed: 1996-08-20
Abstract: PROBLEM TO BE SOLVED: To obtain a mode eigenvalue measuring method which enables estimating of a wave number spectrum with higher resolutions to allow the estimation of a mode eigenvalue value even when a measuring distance is not obtained sufficiently from the levels of a sound source and a noise and environmental conditions of the ocean. SOLUTION: In this method, a normal mode eigenvalue is determined 5 by a Fourier transform 2 and a Hankel transform 3 from a time-series received signal/collected by a submarine transducer. At this point, a wave number spectrum obtained by the Hankel transform is given an initial estimated value proportional to the wave number spectrum and with increased sample data by interpolation to calculate a sensitivity characteristic of a window of the Hankel transform. A convolution of the initial estimated value and the sensitivity characteristic is performed to correct the initial estimated value from a difference between the wave number spectrum obtained by the Hankel transform and the results of the convolution.  Moreover, the correction is repeated until a difference between the initial estimated value and the corrected initial estimated value is held below a specified value to accomplish a processing with higher revolutions (4) for estimating the wave number spectrum.

Abstract: PURPOSE:To measure a wide range of temperature at a high accuracy, by providing a frequency measuring circuit for measuring oscillation frequency of a thermosensitive oscillation circuit to stratify the frequency-temperature characteristics in terms of frequency. CONSTITUTION:This apparatus comprises a thermosensitive oscillation circuit 12, equipped with a thermistor, in which the frequency varies exponentially according to changes in the temperature and a frequency measuring circuit 13 for measuring the oscillation frequency and a frequency data (f) from the circuit 13 is converted to a temperature data T with a temperature conversion circuit 9 to be displayed 10.

Title: Wide-band pulse pattern generator
Inventor: HAYASHI YOSHIO
IPC: G06F1/025
Filed: 1990-08-20
Abstract: PURPOSE:To perform proper re-timing with less deterioration of waveform by providing an intermediate re-timing circuit in the middle of multiple cascade- connected circuits and supplying the output clock of the frequency dividing circuit of the corresponding stage to the intermediate re-timing circuit as a re-timing clock with no substantial delay. CONSTITUTION:Since re-timing is performed by means of an intermediate re- timing circuit 27 by means of the Q-output of a frequency dividing circuit 12n-m irrespective of the transfer of the input pattern of the circuit 27, each delay time after a multiplex circuit 14m+1 can be used as delay time for obtaining multiplex controlling clocks to multiplex circuits succeeding the circuit 27. Therefore, the delay time of a delay circuit 15n for obtaining the multiplex controlling clock to the multiplex circuit 14n in the final stage becomes taun+taun-1+...+taun-1 having no relation with the delay time of the pattern of each section on the preceding side of the circuit 14n and, as a result, the delay time of a delay circuit 15n for obtaining the re-timing clock to a retiming circuit 16 becomes taum+...+taun+T0 which is remarkably smaller than the conventional delay time.
