Filed: 1990-11-05
Abstract: PURPOSE:To accurately correct a black level by detecting a difference between the black level of an analog electric signal and a prescribed voltage and obtaining the picture information voltage of the input analog electric signal from the prescribed voltage by means of a correction value obtained from averaging. CONSTITUTION:Reflected light from an original illuminated by a light source is light-received through an image-forming optical system, and is converted into the analog electric signal. For making the black level of the analog electric signal into the prescribed voltage, the difference between the black level of the input signal and the prescribed voltage is detected by using a black level difference detection means C. Furthermore, the black level difference is averaged by using a black level difference adjustment means D from the black level difference and the correction value is obtained as against the input signal. Then, the picture information voltage of the desired input signal is obtained from the prescribed voltage by using a correction operation means E. Thus, the correction of the black level can accurately be obtained.

Title: Formation of electrode wiring of semiconductor device
Inventor: NAKADA RENPEI
IPC: H01L21/3205
Filed: 1986-12-16
Abstract: PURPOSE:To make it possible to form the pattern of a minute electrode wiring using a high melting point metal film, by treating the surface in an atmospheric gas including oxygen or halogen before the high melting point metal film is formed on the electrode wiring pattern. CONSTITUTION:An SiO2 film 2 as an insulating film is formed on an Si substrate 1, on which a desired impurity layer is formed. An electrode window is provided in the film 2. Then, a W film having a thickness of e.g. about 500 Angstrom  is formed on the entire surface of the substrate by a CVD method. With the substrate being kept in a CVD apparatus, the surface is treated in a halogen gas atmosphere for 10 minutes. Thereafter, a photoresist pattern is formed by ultraviolet exposure in accordance with an ordinary step. The W film 4 is patterned by a reaction ion etching method using fluorine gas, and an electrode wiring is formed. High melting point metal acts with halogen at low temperature. The oxide or halide of the high melting point metal formed in this way is very liable to sublimate. The sublimating speed at a protruding part is faster than that in a recess part. Therefore, the surface roughness is eliminated by the surface treatment at the sublimation temperature or higher.

IPC: H04N9/097
Filed: 1995-10-20
Abstract: PROBLEM TO BE SOLVED: To provide a spectral picture whose desired number of multiple wavelength bands are satisfactory by dispersing a light flux passing through an image-reforming optical system into plural light fluxes having the prescribed wavelength bands and detecting plural images formed based on the plural dispersed light fluxes. SOLUTION: An objective system 1 is the optical telecentric system on an image-side, and the image-reforming optical system 3 is the telecentric optical system on both sides. Light from the image formed through the objective optical system 1 is dispersed into the plural light fluxes having the prescribed wavelength bands.

Thus, the multiple images having the prescribed wavelength bands are formed and the spectral picture having the prescribed number of the multiple wavelength bands can be obtained.

Filed: 1987-11-25
Abstract: PURPOSE: To compress time base so that the frequency change cannot be sensed by detecting the level difference of sound data and discriminating whether it is zero or not by comparison to perform the extraction control of data. CONSTITUTION: Conversion data (m) of sound (a) is inputted to a detector 4 from a memory 1 as data (e), and level difference detection data (f) is inputted to a comparator 5 and is compared with zero to send data (g) to an extraction controller 8. A control signal (h) is sent to a counter 3 and the controller 8 from a counter 2. The counter 3 outputs a control signal (i) for each count of the number of groups, and an adder 7 adds and sets data (d) of a counter 6 and compression rate data (c) by the signal (i). In accordance with a control signal (j) indicating whether the counter value is zero or not, a signal (h), and data (g), the controller 8 sends a data extraction control signal (k) to an extractor 9 not to input sound data from the memory 1 to a memory 10.  Data processed by the extractor 9 is stored in the memory 10 and becomes compressed analog sound (n) after completion of sound data storage. Thus, the time base is compressed.
