Title: Full color image forming method
Inventor: SAKAI TOSHIO
IPC: G03G15/01
Filed: 1990-02-28
Abstract: PURPOSE:To faithfully reproduce an original image by respectively separating and developing a full color image of the color area and a pure black tone image of a black-and-white area of the original image. CONSTITUTION:After electrostatically charging the respective layers U, M and L of a composite photosensitive body to be positive-negative-positive or negative-positive- negative, the color image information of cyanogen, magenta and yellow in the color area and the black-and-white image information in the black-and-white area are respectively put on respective wavelength light beams to simultaneously expose the composite photosensitive body, and an electrostatic latent image is formed so that the absolute value of the black image potential of the color area may be lower than that of the black-and-white image potential of the black-and-white area. Furthermore, by applying developing bias which is higher than the black image potential of the color area, the black-and-white area is developed with the black toner and then only the black-and- white area is uniformly exposed. After erasing the electrostatic latent image, the electrostatic latent images of the respective color of respective photoconductive layers are successively superposed and developed with the toner of the corresponding color. Thus, the black-and-white image part of the original image is faithfully reproduced in the pure black tone.

Title: Automatic focusing method
Inventor: HIDESHIMA TAKAHIRO
IPC: G03B13/36
Filed: 1987-03-05
Abstract: PURPOSE:To improve focusing accuracy by reducing the influence of stepwise voltage variation caused between the effective part and ineffective part of the high frequency component of the output of a line sensor. CONSTITUTION:Projection image information incident on an image sensor is read as a time-series output signal within a read time, a high frequency component obtained by filtering said output signal is rectified on a half-wave basis and begins to be integrated behind an effective output signal for an effective picture element of an image sensor, and this integral value is used to decide focusing. Namely, the high frequency component C of the time-series output signal B of the image sensor contains false signals C1 and C2, but this high frequency component C is rectified on a half-wave basis to erase the false signal C2. Further the integration is started t1 after the false signal C1, so the false signal C1 is put outside an integration range and this integral value E, therefore, contains either the false signal C1 or C2. Consequently, focusing control accuracy is improved.

Water passes through the adsorbing filter material 3 to be equally collected in the respective small chambers by the water collecting branch pipes 5 provided to the bottom parts of the small chambers and discharged by a treated waste water pipe 6 erected in order to always hold the filter material to the state immersed in water. Slit like opening parts are provided to the partition walls 2 so as to equally distribute inflow water to the fronts of the adsorbing beds when the heights of the packed beds of the cartridges 4 are changed. By this constitution, agricultural chemicals can be separated and removed from waste water under low pressure loss.

Title: Cyclic type digital filter
Inventor: YAMAZAKI MITSUO
IPC: H03H17/04
Filed: 1989-02-28
Abstract: PURPOSE:To obtain the cyclic type digital filter without using a multiplier by executing an operation for multiplying by -1/2<a> and subtracting '1' therefrom by a bit shifting circuit and a polarity inverting circuit, adding its result to a value before the shift, and also, adding '1' thereto. CONSTITUTION:An output B1 of an adder 11 is multiplied by 1/2<2> by a bit shifting circuit 12, and thereafter, brought to '1' clock delay by a delaying circuit 13, inverted by a polarity inverting circuit 14 and comes to an input D1 to an adder 16. On the other hand, the output B1 is brought to '1' clock delay by a delaying circuit 15 and comes to a signal F1, and comes to a second input signal to the adder 16. In such a case, when each signal is considered by a two's complement display, the signal D1 becomes a signal being smaller by '1' than a signal obtained by multiplying the signal B1 by (-1/2<2>). Therefore, it is necessary to add '1' by the adder 16. When the signal D1, the signal F1 and '1' are added by the adder 16, an output C1 of the adder 16 comes to (1-1/2<alpha>)=L(2<a>-1) folds, and as a result, an operation being equivalent to a multiplier is executed.

Title: Synchronizing signal generator
Inventor: MITSUOKA KAZUNORI
IPC: H04N9/44
Filed: 1988-03-01
Abstract: PURPOSE:To always make the output period of a synchronizing signal and a period till the production of the synchronizing signal from a reference time constant without being affected by the temperature change by applying logic operation to the output signal of a frequency division means. CONSTITUTION:When signals l3, l4 including a signal to be detected started after the elapse of a 1st period are inputted from a reference time, frequency division means 2, 3 output plural kinds of frequency division signals based on a signal of a prescribed frequency. Logic operation means 4-6 apply logic operation to plural kinds of the frequency division signals to vary the output level of the synchronizing signal output l5 after the elapse of the 1st period. A stop means stops the operation of the frequency division means based on the change in the output level of the logic operation means. Thus, without minute change in the timing due to temperature, the synchronizing signal whose stability is far improved is obtained accurately.
