Title: Brake system
Inventor: TAKASAKI YOSHIYASU
IPC: B60T8/40
Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To positively apply the brake while supplemental braking force is being applied when it is judged that braking force is short, and furthermore try to simplify its system. SOLUTION: ABS control is executed by controlling an intake change-over valve 18 and an ABS controlling modulator 12, and TRC control is also executed by setting the intake change-over valve 18 in a place I, and also controlling pump 11 and a TRC control valve 14. Besides, braking force supplemental control is executed by setting the intake change-over valve 18 in the place I and controlling the pump 11. In this place, even if braking force supplemental control is executed by a supplemental pressure adjusting valve 17, the braking fluid pressure of a braking cylinder 8 can be continuously and smoothly increased. By this constitution, a driver will never has a sense of incompatibility with respect to change in braking force against footing force.  Thus as mentioned above, three kinds of control including ABS control, TRC control and braking force supplemental control can thereby be executed by one pump 11.

Abstract: PURPOSE:To improve the reliability of wiring a semiconductor device by forming an insulating film on a semiconductor substrate on which electrodes are formed, covering selectively a mask on the insulating film, burying organic material around the insulating film on the electrodes and then opening contacting holes. CONSTITUTION:A silicon oxide film 12 is formed on a semiconductor substrate 11, and an electrode wire 13 made of polycrystalline silicon film is formed thereon. A phosphorus-adding silicon oxide film 14 is accumulated thereon in the same thickness the wire 13 by a vapor phase growth. Subsequently, a resist film 15 is covered as a mask on the film 14 excluding the part becoming a contacting region. Thereafter, when a plasma etching is conducted after organic material such as polyimide or the like having low viscosity is covered on the entire surface, the organic material 19 is buried only in the recess between the films 15 and 14. Eventually, exposed silicon oxide film 14' is removed by ion etching, the organic material 19 and the resist film are molten, and then an aluminum wire 21 is formed by an ordinary method. Since the surface of the substrate is flat, the yield of the wiring is high.

Title: Picture data processing system
Inventor: SAKAGAMI HIROFUMI
IPC: H04N1/41
Filed: 1990-03-07
Abstract: PURPOSE:To partially change picture quality in one picture while holding compatibility with a conventional stretch processing by changing a high frequency component in a block corresponding to the position of the block in one picture. CONSTITUTION:In respect to a transform coefficient Fuv [(u) and (v)=0, 1, 2,..., (n)-1] after discrete cosine transform or quantization, a control variable (l) is set for each block and a processing is executed to set the value of the transform coefficient Fuv satisfying the condition of (l)<=(u)+(v) to zero. Then, the high frequency component of the transform coefficient Fuv is changed for each block. In a figure showing the change of the value of the variable (l) in each block of one picture, for example, the block positioning at the center of the picture sets the (l) to 14 and the other block sets the (l) to 4. Thus, while keeping compatibility with the conventional picture data processing system, the picture quality is partially changed in one picture.

Title: Instrument for measuring nitrogen compound in water
Inventor: TADA MINORU
IPC: G01N21/77
Filed: 1987-03-09
Abstract: PURPOSE: To measure the respective components of the nitrogen in sample water by measuring nitrate nitrogen and nitrite nitrogen without oxidizing the water and subjecting the entire nitrogen compd. in the sample water to oxidation decomposition to convert the same to nitric acid ions, then making the measurement.  
     CONSTITUTION: The sample water is supplied by a water sampling pump 9 to a reaction vessel 1. The sample is fed by a dispensing pump 10 to a UV absorption photometer 2 which makes the measurement with 3 different wavelengths to measure the nitrate nitrogen (NO 3   - -N) and the nitrite nitrogen (NO 2   - -N). Caustic soda is then supplied from a tank 5 and hydrochloric acid from a tank 4 to a reaction vessel 1 to adjust the pH to a prescribed value. Ozone is supplied from an ozonizer 6 to the vessel 1 to decompose the nitrogen compd. in the sample water by oxidation to the NO 3   - -N. The NO 3   - -N formed by the oxidation decomposition is thereafter measured by the UV absorption photometer 2. The respective components of the nitrogen component are then determined from the measured values of the NO 3   - -N, NO 2   - -N and the NO 3   - -N formed by the oxidation decomposition in an arithmetic part 3. The nitrate nitrogen, nitrite nitrogen and total nitrogen are, therefore, exactly measured without being affected by org. matter and suspended solids.

Title: Frequency-wavenumber spectrum analysis method
Inventor: SATO YOICHI
IPC: G01V1/00
Filed: 1998-03-05
Abstract: PROBLEM TO BE SOLVED: To obtain the dispersion characteristics of an optimum Rayleigh wave quickly by limiting the search range of the peak of a wavenumber spectrum to the phase speed and the frequency of the Rayleigh wave. SOLUTION: A method consists of a controller 1 for obtaining the dispersion characteristics from the control of equipment and the peak of a wavenumber spectrum, a exciter 2 for vibrating a ground surface 4 based on a control signal from it, and a vibration detector 3 for detecting a propagated vibration wave. Nine detectors 3 are arranged on a straight line passing through the exciter 2 with an interval of 25 cm. The controller 1 first detects a Rayleigh wave from a vibration wave that is sent from the nine detectors 9 and calculates the phase speed of the Rayleigh wave. The phase speed can be obtained by obtaining the peak of the wavenumber spectrum for each frequency and by dividing the angular frequency by the absolute value of the wavenumber spectrum for indicating the peak position.  The search range of the spectrum can be limited by the phase speed and the frequency of the Rayleigh wave and optimum Rayleigh wave dispersion characteristics can be obtained efficiently with less amount of calculation.

Title: Matching pattern signal generating method in pattern matching inspection and device thereof
Inventor: HANABUSA HIDEYUKI
IPC: G06T7/00
Filed: 1993-03-15
Abstract: PURPOSE:To make any defect in a mast area effectively detectable by extracting each of both first and second contouring parts crossing and paralleling the scanning direction and then performing a mast expansion process for pattern matching separately. CONSTITUTION:A first difference processing circuit 8 extracts a first contouring part, crossing the scanning direction of a camera, from a difference between a camera signal A not passing through a delay line 9 and a delay camera signal B, outputting a signal of first contouring data C. The data C are binary-coded (10), and master first contour binary data D2, imparting an expanded master area to this data C is outputted (11). In addition, an AND circuit 7 inputted with real first binary-coded data F binary-coded the data C inputs corresponding data E into a first memory 5 synchronously, and when there is a difference after pattern matching, a signal G is outputted. When a defective object inclusive of this signal G is more than the specified size, a defect is judged (12). On the other hand, a second contouring part in parallel with the scanning direction is extracted (28), and a defective judgment (32) takes place with the same processing as the first one. Therefore a defect in one side mask area is situated at the outside of the other side mast area, whereby it is effectively detectable.
