Title: Video signal clamp circuit
Inventor: HAYASHIDA FUJIO
IPC: H04N5/18
Filed: 1988-04-26
Abstract: PURPOSE:To relieve the noise component superimposed on the tip of a horizontal synchronizing pulse from being converted into noise by inverting the noise component of the tip of the horizontal synchronizing pulse in a video signal and adding the result in a clamp circuit. CONSTITUTION:A clamp pulse generating circuit 6 outputs a clamp pulse in response to the timewise location of the horizontal synchronizing pulse inputted to a switch circuit 7. A branch circuit 9 branches a video signal and gives an output to an output terminal 4 and a slice circuit 10. The circuit 10 outputs the synchronizing pulse information at the tip of the horizontal synchronizing pulse to an inverse amplifier 11 and outputs it to a coupling circuit 13 via a high pass filter 12. The circuit 13 adds the output from an HPF 12 to the output of a clamp level generating circuit 8 and outputs the result to the circuit 7. The switch of the circuit 7 is closed at the clamp pulse time from the circuit 6 to apply the signal from the circuit 13 to the circuit 9. Thus, even if noise is superimposed onto the tip of the horizontal synchronizing pulse, the noise component of the signal supplied from the circuit 7 is reduced by the DC voltage deciding the clamp level and the voltage cancelling the noise.

Abstract: PROBLEM TO BE SOLVED: To easily observe a two-dimensional/three-dimensional compatible image with no moire over a wide range by displaying a two-dimensional image with no picture element degradation while using distributed liquid crystal as a diffusing effect ON/OFF panel. SOLUTION: A distributed liquid crystal panel (diffusing effect ON/OFF panel) 106 transmits light at the time of voltage impression but scatters light at the time of no impression. When displaying a three-dimensional image, video signals are applied to a liquid crystal panel 101 so that the 1st picture element group of the liquid crystal panel 101 can be used for the right eye and the 2nd picture element group can be used for the left eye. The distributed liquid crystal panel 106 turns off a diffusing effect and does not scatters light from a beam splitting means 110 but transmits it. The left and right images are separated, the image for right eye arrives at a right eye 116 of an observer 115, the image for left eye arrives at a left eye 117, and the three-dimensional image is recognized.  When displaying a two-dimensional image, the diffusing effect on the distributed liquid crystal panel 106 is turned on, light from the beam splitting means 110 is scattered and the observer 115 watches all the picture elements on the liquid crystal panel 101 in both eyes 115 and 116 so as to watch the two-dimensional image with high picture quality.

Title: Power system simulator
Inventor: OI MAKOTO
IPC: G06F19/00
Filed: 1996-04-25
Abstract: PROBLEM TO BE SOLVED: To make it possible to control simulation so that a computation accuracy of the simulation can be improved, by obtaining the data showing the computation accuracy of the simulation through a display and setting computation parameters to comply with the conditions and giving the set data to a simulation computation means. SOLUTION: By computating the data about the information which shows a relational expression between the number of repetitions and the computation accuracy of a repetitive computation, the minimum number of repetitions for realizing a specified computation accuracy can be obtained. Therefore, an operator does not need to adjust the minimum necessary number of repetitions and can save labor. In other words, the number of repetitions to give the fastest computation speed for realizing the specified computation accuracy can be obtained at the same time. And, if the number of repetitions is reduced, the computation time of one cycle can be shortened and thereby the computation speed of simulation can be increased. By this method, the computation speed of simulation can be increased with the specified computation accuracy being unchanged.
