Title: Isolated point elimination device
Inventor: MATSUBARA TOSHIYUKI
IPC: H04N1/405
Filed: 1990-07-31
Abstract: PURPOSE:To prevent deterioration in picture quality by clearing an error data stored in an area in which a change in a picture element density is discriminated to be small and the picture element density is near a minimum value. CONSTITUTION:A peak hold detection section 10 holds a maximum value of a difference in a picture element unit in an error data calculated by a subtractor 6. An isolated point discrimination section 11 receives an output binary data being an output of a comparator 8, a maximum value of an error data stored in the detection section 10 and a prescribed threshold level T' respectively. Then the discrimination section 11 recognizes a maximum value of a difference from the detection section 10 when a black level picture element is caused from an output from a comparator 8, and corrects the output binary the prescribed threshold level T' (equal to T in this embodiment) and the maximum value of the difference is smaller than the prescribed threshold level T' as the result. Moreover, a reset signal is generated in addition to the processing above to reset a buffer memory 4. Then the error data is discriminated in excess of a half of the gradation number at first in a low density area by applying error diffusion processing to the error data of a noted picture element 25.

Abstract: PURPOSE:To obtain an image without a flicker even with a public VTR by executing photoelectric conversion to two image signals obtained from different optical system parts for one field period respectively with more than one piece, and recording and reproducing the time-divided image signal. CONSTITUTION:A shutter 101 of an optical system part 10 executes opening/closing mutually in right/left with a field frequency. Incident light passing through different routes or right and left is synthesized by a mirror 102 and a half mirror 103 and image-formation is executed through an image-formation system 104 on the image pickup surface of an image pickup element 111. At such a time, since an R image and an L image are image-formed on the element 111 for one field period, the element 111 is driven at the double speed of the normal speed. The output of the element 111 is removed by a memory 112 and a switch 113 and the signal of the R image and the L image are outputted from an image pickup part 11 in time-division. The signal is sent to a signal processing part 12 and the recording and reproducing are executed by a recording reproducing part 13 in the same way as a standard TV signal. Thus, a three-dimensional image can be obtained without the flicker even with the public VTR.

Filed: 1987-08-19
Abstract: PURPOSE:To quickly detect the off-track quantity of a data head on a real-time basis by alternately writing two patterns for off-tracking detection so that they may not overlap each other on a single track of the data surface of a disk. CONSTITUTION:Off-track quantity detecting patterns are alternately written (ODDEVEN pattern) on a single track of the data surface of the disk by offsetting the patterns at a certain interval (d) in the reverse and forward directions from the center of the track so that the patterns will not overlap each other. When an off-track quantity is detected, both patterns for off-track detection on the track are read, and the patterns are composed on the basis of the level difference between both patterns so that the off-track quantity can be detected. Thus, it is possible to quickly detect on real-time the off-track quantity of a data head, and it is also possible to detect the variation of the off-track quantity of the data head on one circling of the circumference of the track.

IPC: G21C7/26
Filed: 1998-07-21
Abstract: PROBLEM TO BE SOLVED: To reduce operations of a control rod or the like, by obtaining an allowable maximum output for a rotational speed of a recirculating pump stored in a controller before a driving operation such as a control rod operation or the like, and comparing a reactor core output after the driving operation with the maximum output. SOLUTION: Before a control rod operation, it is confirmed that a reactor core output point and a reactor core flow rate are within driving allowable ranges. Then, a reactor core output after the operation and a radial peaking of each fuel aggregate are calculated by a processor 2 from data for controlling drawing position of rod and a drawing amount. Thereafter, a radial peaking maximum value after the driving operation and a radial output distribution exponential value are calculated by a radial peaking maximum value and R value calculator 9, and an allowable maximum output at a rotational speed of the pump is obtained by an output comparator 10 by using the result and a present pump rotational speed. The maximum output is compared with an output after a controlling operation for drawing rod. When it is lower than the allowable maximum output, the operation is executed.  When it is the allowable value or more, the speed of the pump is accelerated.

Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor laser having a constitution which stabilizes NFP. SOLUTION: This semiconductor laser 10 has a double-heterojunction multiplayer structure of a 1st buffer layer 14, a 2nd buffer layer 16, an n-type clad layer 18, an active layer/guide layer 20, a p-type clad layer 22, and a p-type cap layer 24 on a substrate 12.

In the upper pat of the p-type cap layer 24, thin belt-like current non-injection regions 28 extend parallel to the border line of the current noninjection regions 26. When a current is injected, in this semiconductor laser device 10, the carrier density in a part 34 in the active layer 20 directly below the current non-injection regions 28 provided in the stripe is lower than that in the other parts. Consequently, a gain distribution is generated in the active layer 20 and a lateral mode is confined, so that NFP becomes stable.
