Title: Digital filter for decimation
Inventor: KANEAKI TETSUHIKO
IPC: H03H17/00
Filed: 1988-07-22
Abstract: PURPOSE:To form the filter by a small scale register and to reduce the number of times of calculations by decreasing the sampling frequency by means of the 1st digital filter having a gentle characteristic and the 2nd digital filter having a steep characteristic thereby obtaining a desired sampling frequency. CONSTITUTION:A 1st digital filter(DF1) 1 applies filtering and decimation to a digital signal inputted at a sampling frequency 4Fs and converts the sampling frequency into a frequency 2Fs and outputs the resulting frequency. Then a 2nd digital filter(DF2)2 converts the sampling frequency 2Fs into a frequency Fs and outputs the resulting frequency. In this case, since the filter DF1 has 24 taps and the filter DF2 has 145 taps, in total 169 registers are enough for the purpose, and the number is less than a conventional number (256). Moreover, the number of times of calculations in the DF 2 is 145 in one period T, 193 is enough in total and it is less than a conventional number (256). Furthermore, the number of times of calculations in the DF 1 is 24 in a period of 1/2T and that in the DF 2 is 145 in the period T, which amount to 193 in total and it is less than a conventional number of times (256).

Title: Method for making plural copies
Inventor: YAMAOKA TOSHIHIDE
IPC: G03G13/08
Filed: 1982-10-22
Abstract: PURPOSE:To obtain copies having good image quality, by developing an electrostatic latent image with a toner having dielectric constant at a specified value or lower in repeating development and transfer using only one electrostatic latent image once formed on a charge retaining material to obtain plural sheets of copies. CONSTITUTION:When an electrostatic latent image is developed, a developed toner image is formed on the electrostatic latent image. At that time, charge is generated in the toner layer in accordance with the electrostatic capacity by electrostatic induction from the electrostatic latent image. A part or the total amt. of this charge is simultaneously consumed when the developed toner is consumed from the development step to the transfer step, and as a result, charge of the electrostatic latent image is attenuated. In the case of making plural copies, such consumption of charge of the latent image is repeated with respect to the same one image, and therefore, it is presumed that this is one of the factors deteriorating the electrostatic latent image. Such transfer of charge from the latent image to the toner layer becomes smaller, as the electrostatic capacity of the toner layer becomes smaller, that is, the dielectric constant of the toner becomes smaller, and to satisfy the requirements of practicable image quality, the dielectric constant must be reduced to <=3.5.

Filed: 1996-07-16
Abstract: PROBLEM TO BE SOLVED: To suppress reduction of air sending performance under a high static pressure condition and increase of turbulence noise by setting a minimum impeller inlet diameter and the outer diameter of an impeller to a specified range, inclining an upper end part in an impeller rotational direction, and set an impeller inner circumferential side upstream side end part and a side plate side upstream side end part to nearly the same distance from a main plate. SOLUTION: The minimum impeller inlet diameter D1 of an impeller plate 9 is set to 0.65D2 <=D1 <=0.8D2 (D2 is the outer diameter of an impeller 8). An impeller inlet diameter Dt on the end part 11a of the side plate 11 of the impeller plate 9 is enlarged larger than the impeller inlet diameter of a main plate 10 side, and larger than the suction port diameter Ds of the side plate 11. The upper end part of the impeller plate 9 is inclined in the rotational direction of the impeller 8, and the distance h3 of the upstream side end part 9t of an impeller 8 inner circumferential side from the main plate 10 is formed in a distance similar to the distance h4 of a side plate end part 11a.  It is thus possible to suppress separation of air current on an impeller negative pressure surface, suppress reduction of air sending performance in the case where operation is carried out at a high static pressure operating point, and suppress increase of turbulence noise in association with separation of flow.
