Title: Video signal a/d convertor
Inventor: ODATE KAZUYUKI
IPC: H04N5/66
Filed: 1985-12-05
Abstract: PURPOSE:To utilize gradation range effectively and to improve contrast by passing signal through an LPF and taking out low band part, and A/D converting after controlling amplitude of video signals to a fixed value by the signal of the low band part. CONSTITUTION:Luminance signals (a) sent from a video amplifier circuit are inputted to an LPF 15 through a capacitor 14. Output signals of the LPF are inverted by an inversion amplifier 17 and inputted to a video chroma signal processing circuit 11 through a resistance 18 together with a contrast adjusting signal. Output of the circuit 11 amplifies signals (a) according to the contrast adjusting signal, and at the same time, separates signals of three primary colors according to chromaticity signals and outputs to A/D convertors 19-21 for each chrominance signal. Convertors 19-21 convert chrominance signals R, G, B from the circuit 11 to digital signals DR1-DR4, DG1-DG4, DB1-DB4 according to the upper limit reference voltage VH and lower limit reference voltage VL and output to a display circuit.

Title: Treatment of phosphate ion-containing waste water
Inventor: MURAYAMA KATSUO
IPC: C02F1/58
Filed: 1990-10-12
Abstract: PURPOSE:To prevent fine crystalls from occurring frequently and to form a precipitate reduced in precipitation volume and good in filterability by suspending hydroxyapatite in a reaction tank and using the same as a nucleus to crystallize phosphorus. CONSTITUTION:Phosphate ion-containing waste water is continuously introduced into a reaction tank having hydroxyapatite preliminarily suspended therein to precipitate phosphorus at constant pH7-10.5. At this time, the addition amount of calcium is a theoretical amount or less but it is unnecessary to especially add a calcium salt. The concn. of phosphorus is logarithmically reduced with the rise of pH but this pH and the concn. of phosphorus can be calculated by a preparatory test. When the concn. of phosphorus in the water to be treated of the first tank reaches an objective value, the second tank is unnecessary. When the removal ratio of phosphorus is insufficient only by the first tank, waste water is sent to the second tank without performing solid-liquid separation and a calcium salt is added thereto. Since the concn. of residual phosphorus becomes an almost constant value with respect to low pH, the amount of the calcium salt added in the second tank can be easily determined.

Title: Gear wheel with damper
Inventor: OUCHI YOSHIRO
IPC: F16F15/124
Filed: 1985-12-06
Abstract: PURPOSE:To enable cushioning without reducing the engagement accuracy by providing a toothed wheel loose-fittedly supported on a supporting shaft and a boss part fixed on the supporting shaft so as to be adjacent, and combining the space between a ring-shaped outer ring projectedly formed from the side of the toothed wheel and the outer surface of the boss part with a damper rubber. CONSTITUTION:In a reduction gear 6d, the space between the boss part B press-fitted on an output shaft 6b and a toothed wheel R is combined with a baked rubberlike elastic body E. An end plate 63 extending from the end of the toothed wheel R toward inside prevents the shaft center of the toothed wheel R and that of the boss part B from becoming eccentric by a transmission force. A restricting device 8 is made up of recesses 64 on the end plate 63 and projections 65 on the boss part B, and it is so arranged that each of the recesses 64 and the projections 65 when assembled has clearances 66 on both sides. Accordingly, when the deformation of the elastic body E during power transmission is within the range of the clearances 66, the restriction is not caused, and when the deformation of the elastic body E becomes large enough, the projections 65 are brought into contact with the inner walls of the recesses 64 to prevent further turning, and the sudden change in the driving force acting on a rearwheel driving system can be relieved.

Title: Radiation inspection device
Inventor: NISHIDE AKIHIKO
IPC: G01N23/04
Filed: 1984-12-28
Abstract: PURPOSE:To discriminate correctly a defect without the influence of the change thereof with lapse of time by subtracting transmitted image data by a standard mask pattern to determine the difference in the various density image and updating the standard mask pattern by the defect-free image data. CONSTITUTION:X-rays are transmitted through a specimen 12 from an X-ray tube 13 and the transmitted X-ray quantity is detected by an X-ray detector 15. The detected X-ray quantity is converted to an electric signal and thereafter the transmitted image data is quantized by the prescribed various density value in an analog-to-digital converter 16 and the result thereof is inputted to a CPU20. The transmitted image data is subtracted by the standard image mask pattern and the difference in the various densities for each of the picture elements is determined, from which the size of the specimen is determined. The size larger than a prescribed set value is discriminated as a defect. The transmitted image data discriminated as defect-free data is taken into the standard mask pattern, by which the standard mask pattern is updated. Since the subtraction is executed by the standard mask pattern updating the transmitted image data, the defect of the contour part is exactly detected and the correct discrimination is made possible by following up to the change with lapse of time in the stage of inspection.

Also, the phase detector 19 outputs the phase θi of the input current at the point of time when the very short time signal S1 is changed from 1 to 0 to the initial magnetic flux estimation device 20. The magnitude, the phase and the rotational speed of the residual magnetic flux is estimated to generate the signal of a frequency initial value F10 corresponding to the rotational speed in an acceleration and deceleration limiter 3'. Therefore, a frequency command F1' by which a frequency initial value F10 is adopted as an initial value to a frequency initial value F* is set when the starting signal Soo is 0 in the acceleration and deceleration limiter 3'. As a result, smooth start is realized.

Namely, the sum of the numbers of times of execution at the page blocks registered on the list of both the basic blocks is calculated corresponding to a pair of two arbitrary memory parameters at different basic blocks, and two memory parameters which sum is maximum is allocated to the continuous memory areas. Then, the memory parameters to be used for the same basic block gathered into one parameter are allocated to the adjacent area on the main memory.
