Filed: 1999-09-28
Abstract: PROBLEM TO BE SOLVED: To solve a problem where a pattern of photolithography is constricted or a part is left un-etched when a gate electrode is etched in an after process where a gate electrode is formed. SOLUTION: A pad oxide film 2 and a silicon nitride film 3 are deposited on a silicon substrate 1, then photoresist is applied thereon, and an opening is provided to a region which is to serve as an element isolation region where photoresist is applied. Then, a groove 5 is provided to the substrate 1 by dry etching using a photoresist pattern 4 as a mask. Then, after the photoresist pattern 4 is removed, a USG film 7 and an LTO film 8 are successively deposited so as to fill up the groove 5.

Title: Absorbance measuring apparatus
Inventor: NISHIMOTO MASAJI
IPC: G01J3/42
Filed: 1990-10-13
Abstract: PURPOSE:To make it possible to measure samples of a wide concentration range without dilution by changing the wavelength and performing measurement again when the measured light value of the sample is located at the outside of a dynamic range. CONSTITUTION:A measuring wavelength is set with a wavelength changing means 18. The measuring light having the specified wavelength is emitted from a light emitting means 10 on a sample 14. The light is received with a light receiving means 12 and undergoes photoelectric conversion. Thus, the light is measured, and the measured light value is obtained. Then, in a dynamic-range judging means 16, whether the measured light value is located in a dynamic range or not is judged. When the value is located outside of the range, the emitted light from the means 10 is changed and reset with the wavelength changing means 18, and the measurement is performed again. When the value is within the range, the value is corrected with the correcting coefficient based on the wavelength set with the means 18 in a measured-light correcting means 20. The corrected measured light value is outputted. The concentration of the sample is operated based on the corrected measured light value by using a calibration curve and displayed on a display 26.

Title: White peak suppressing circuit
Inventor: ONDA TETSURO
IPC: H04N5/20
Filed: 1985-12-05
Abstract: PURPOSE:To suppress white peak value effectively by making white peak level constant by stopping operation of a switching circuit when the width of white peak is narrow, and charging a capacitor to make the switching circuit on and lowering contrast adjusting voltage when the width is large. CONSTITUTION:When white peak of outputted video signals exceeds the threshold value, base potential of a transistor TRQ11 becomes larger than base potential of TRQ12 and charging of a capacitor C11 is started. In this case, when the width of white peak is small, a white peak suppressing circuit does not respond contrast is not changed. When the width of white peak is large, if the white peak exceeds a threshold value V11, white peak detection current flows and the capacitor C11 is charged by current I11-I12=I12. When base potential of TRQ15 exceeds the threshold value level V12, collector current i0 flows in TRQ20. Consequently, contrast adjusting voltage is lowered and contrast is reduced and amplitude of output signals is decreased. Thus, the white peak level can be kept at a fixed value.
