Title: Digital convergence compensator
Inventor: TANAKA TOSHIAKI
IPC: H04N9/28
Filed: 1982-10-30
Abstract: PURPOSE:To compensate the good performance of convergence by selecting and reading both data preserved permanently and the data written to a memory at a high speed and performs compensation of convergence with one of these two data has higher convergence. CONSTITUTION:The compensation data 2700 of a temporary storage memory 1001 which performs reading/writing at a high speed is supplied to a nonvolatile memory 1004 via a latch circuit 1002. While the data of the memory 1004 is supplied to the memory 1001 via a latch circuit 1003. The level of a control operation signal is switched, and the compensation data on a steady mode of the memory 1004 is transferred to the memory 1001. Then the level is switched for an operation signal which switches the most significant address of the memory 1001. Thus a compensation data having high convergence is selected when a power supply is powered-on. Then the address is switched again in a steady mode to read out the compensation data which has high convergence in a steady mode. In such a way, the misconvergence, if occurs, can be corrected.

Title: Video signal recording and reproducing device
Inventor: SASAKI YOSHIYUKI
IPC: G11B20/02
Filed: 1987-07-30
Abstract: PURPOSE:To attain normal synchronization separation by providing the 2nd low pass filter having a narrower pass band than that of the 1st low pass filter using a video signal band as the pass band for the output of an FM demodulation circuit separately and providing a synchronizing separator circuit to a stage after the output of the 2nd low pass filter. CONSTITUTION:The 2nd low pass filter 8 having a narrower pass band than that of a 1st low pass filter 7 is provided separately to the output of the FM demodulation circuit 6 in addition to the 1st low pass filter 7 taking at least the video signal band as its pass band and the synchronizing separator circuit 9 is provided to a stage after the output of a 2nd low pass filter 8. Since the 2nd low pass filter eliminates the FM signal corresponding to the synchronization tip, the carrier leakage leaked to the synchronization tip is suppressed sufficiently smaller. Thus, the carrier frequency of the frequency modulation is decreased or the deviation is increased to apply normal synchronizing separation even when the frequency corresponding to the synchronization tip is lowered.

Title: Fuel pump control device for internal combustion engine
Inventor: ISOBE SHOJI
IPC: F02M37/08
Filed: 1997-07-02
Abstract: PROBLEM TO BE SOLVED: To largely reduce electric power supplied to a fuel pump driving motor, by determining motor command value based on operation amount for determining minimum amount of pump delivery amount required to keep a target fuel pressure, that is, duty pulse signals supplied to a pressure adjusting valve. SOLUTION: A delivery pipe 16 mounted to a fuel injection valve 10 is connected to a pressure adjusting mechanism 30 via a fuel pipe 14, the mechanism 30 is controlled by a pressure adjusting valve controller 44, and therefore, part of fuel is returned to a fuel tank 12. Output of the pressure adjusting valve controller 44 is input into a pump driving motor controlling circuit 50, and a duty ratio supplied to an electric motor 26 is determined based on the input duty ratio. As actual fuel pressure becomes higher against the target fuel pressure, the duty ratio supplied to the pressure adjusting mechanism 30 is increased, and the duty ratio supplied to the electric motor 26 is determined to be inversely proportional to the change of fuel pressure to decrease rotational frequency of the fuel pump.

Title: Inspection of mask pattern
Inventor: NAKASUJI MAMORU
IPC: G03F1/84
Filed: 1998-06-25
Abstract: PROBLEM TO BE SOLVED: To provide a method capable of carrying out exact inspection even when the pattern formed on a mask of a system to correct a proximity effect by making the size of the pattern different from a design value is inspected for good or not. SOLUTION: There is an extremely large pattern part 5 in a part of a pattern part 4 of the ordinary size. Pattern formation is so executed that the proximity effect at the time of transfer by an electron beam may be corrected at the large pattern part 5, and as a result, the actual pattern 2 is made thinner than the pattern 1 complying with the design value. When, therefore, the inspection of the pattern is carried out by comparing the design size of the pattern and the actually measured pattern detected from the actual pattern edge position, this portion is detected as a defect. The portion, however, is a direction where the pattern is made finer in the direction of correcting the proximity effect and coincides with the direction of the actual pattern 2 and, therefore, the decision of this portion as the defect is averted.

Title: Method for calculating cosine value from vector
Inventor: KIMURA MITSUHIDE
IPC: G06T7/60
Filed: 1990-07-20
Abstract: PURPOSE:To improve speed for calculation by using the coordinate value of a coordinate point applying a square value close to a set value rather than a preceding coordinate point when the square value of a distance from the coordinate origin of a coordinate point, which is calculated by Bresenham algorithm based on the direction of a vector, is larger than the set value. CONSTITUTION:An input device 1 sets a numerical value for applying accuracy for calculation, a device 2 successively calculates coordinate points according to Bresenham algorithm based on the direction applied by the vector, and a device 3 calculates the square value of the distance from the coordinate origin of the calculated coordinate point. When the calculated square value is higher in comparison with the square value of the set value, it is calculated either the square value or the square value of the distance from the coordinate origin of the coordinate point calculated preceding to the above-mentioned coordinate point is closer to the square value of the set value, and a cosine value is calculated from the coordinate value and the set value corresponding to the reference coordinate axis of the coordinate point applying the closer square value. Thus, the cosine value of a rotational angle is calculated at high speed with a small execution module.
