Abstract: PURPOSE:To decrease a pulse noise with a simple circuit constitution by subtracting the output signal of a forecast signal forecasting a present signal from a past input signal from an input signal and feeding back a signal limiting the amplitude of the subtracted output to the forecast signal. CONSTITUTION:A detection signal S including a pulse noise inputted from a terminal 10 is fed to one input of a subtraction circuit 11, the output P of a signal forecast circuit 13 forecasting a present signal from a past input signal is fed to the other input of the circuit 11, and the output of the circuit 11 being the subtraction of the signal P from the signal S is a forecast error signal E. In setting properly the circuit 13, the forecast error is decreased to a steady- state input signal and the error is a large value against a pulse noise, then a signal E' in which noise is suppressed by limiting a level being a predetermined level or above by an amplitude limit circuit 12 is inputted to the adder circuit 16 of the circuit 13, added to the signal P, the output of the circuit 16 is inputted to a terminal 14 and a forecast filter 17, a signal whose noise is suppressed is outputted from the terminal 14 and the signal P is outputted from the filter 17.

Title: Expanding processing method for circle
Inventor: NODA HIDEO
IPC: G06T11/20
Filed: 1999-09-29
Abstract: PROBLEM TO BE SOLVED: To plot a circle without trouble even on the orthogonal coordinate system of horizontal or vertical double accuracy. SOLUTION: The expansion of a circle is performed while using DDA processing for inputting vector data expressing the circle, storing the gradient corresponding value of the vector data in respect to respective coordinate values in the first axis direction of the orthogonal coordinate system specified by these vector data, changing one of coordinate values in the second axis direction of the orthogonal coordinate system at a time point, when the stored quantity exceeds a prescribed value, and forming dots along with the vector data by subtracting the prescribed value from the stored quantity.  When executing DDA processing of the circle on the orthogonal coordinate system having different accuracy in the first and second axis directions, said DDA processing is executed by applying an ellipse having a longitudinal/lateral diameter ratio corresponding to the ratio of accuracy in the first and second axis directions as the vector data expressing the circle.

Abstract: PURPOSE:To separate a dot area with high accuracy by detecting the prescribed picture elements in this small area as a dot candidate are when a count value exceeds a threshold value, deciding it based on the distribution density of this area whether the respective picture elements belong to this area or not, and changing the threshold value corresponding to the magnification of a picture. CONSTITUTION:When the detection of peak picture elements is finished for N lines, a dot candidate area detection part 3 counts a number P of the peak picture elements in a block for each block unit in the size of NXN picture elements and this count value P is compared with a threshold value Pth.

Title: Liquid seal engine mount using piezoelectric element
Inventor: YAMADA TOMOJI
IPC: F16F13/26
Filed: 1994-11-14
Abstract: PURPOSE: To prevent 'high-speed heavy sound' which tends to occur during high-speed travelling of a car whose internal combustion engine is supported by a liquid seal engine mount. CONSTITUTION: A liquid seal engine mount effectively prevents vibration of engine from transmitting to a car body by damping the vibration by means of viscous resistance of incompressible fluid which passes through an orifice when a car travels at low-speed, but generates a high-speed heavy sound due to reduction of flowing volume of the fluid which passes through the orifice when the car travels at high-speed.  Therefore, vibration damping effect is adjusted arbitrarily, by making piezoelectric boards 10 and 11 attached to a diaphragm board 12 by which a main fluid room 13 is divided from a sub fluid room 14, by applying arbitrary voltage to one piezoelectric board from a control circuit 19 or the like as well as detecting deformation of the diaphragm 12, in other words, pressure difference between the main fluid room and the sub fluid room by means of the other piezoelectric board, by controlling the pressure difference by making the diaphragm board 12 deformed in an arbitrary mode, and by controlling incompressible fluid flow which passes through the orifice from outside.

Title: Method and device for correcting jitter of polygon mirror
Inventor: ISONO KOICHI
IPC: H04N1/23
Filed: 1986-11-21
Abstract: PURPOSE:To eliminate the dot shift of a scanning line substantially by transferring N dot recording clock signals wherein the dot shift of a scanning line caused by the error in the rotation of a polygon mirror by t/N each by as many times as the quantity of the dot shift during scanning on one scanning line. CONSTITUTION:When a dot diameter and a dot interval are equal to each other, every four dots in a dot array have a dot shift of d/10, so a dot shift of (d/10) 3 is obtained at the 12th dot at the scanning line end. For the purpose, the N dot recording clock signals phi1-phiN are prepared which are generated by dividing the period (t) of a reference dot recording clock signal phi1 equally by N and delaying them by t/N each. Then the dot recording clock signals are transferred in order in the phase delay direction to generate a transfer dot recording clock signal phiX and a scan is made in synchronism with it. Then, an adjustment is so made in every cycle of the transfer that the scanning length becomes longer by d/10 each, and the dot shift of (d/10) 3 is eliminated completely at the end of the scanning line.
