Title: Controller
Inventor: KASHIWAGI YASUHIRO
IPC: H02P29/00
Filed: 1988-05-06
Abstract: PURPOSE:To always keep a stable control action with a controller by setting a notch filter having the frequency characteristics corresponding to a band having the natural resonance frequency of a controlled system into a control system circuit and suppressing the oscillation of a specified band which is caused by the controlled system. CONSTITUTION:A notch filter 9 has the adverse gain (attenuation) frequency characteristics equal or approximate to the natural high-degree resonance frequency of an actuator 7, i.e., a controlled system of a control circuit. This notch filter 9 is set between a compensating circuit 5 and a driving circuit 6, for example, contained in a servo loop. Thus the open loop gain is reduced by the attenuating function of the filter 9. In such a constitution, a controller having the stable working is obtained with no oscillation of a servo loop even with a controlled system like an optical pickup actuator.

IPC: G03G13/01
Filed: 1977-09-14
Abstract: PURPOSE: To form electrostatic latent images for multichromatic originals by radiating the color light images of the multichromatic original to a photoreceptor having (n) layers of photoconductive layers and potentially separating the colors up to maximum 2 n  colors.  
     CONSTITUTION: A photoreceptor 1 is constituted by laminating (n) layers of photoconductive layers of mutually different spectral sensitivities, e.g., 11, 12, 13 on a consuctive backing 10. This photoreceptor 1 is subjected to primary charging to a specified polarity, e.g., negative polarity, by a charger 2 in the dark or while it is being  evenly radiated with the light which makes the photoconductive layers of the layers (3-2+1=2) from, e.g., the second layer from the top of the three layers of the  photoconductive layers down to the conductive substrate 10 conductive, i.e., the light  having been cut off of the wavelength of the spectral sensitivity of the photoconductive layer 11. Thereby, the surface of the photoreceptor 1 is negatively charged and positive charges are induced on the back of the photoconductive layer and are evenly distributed. Next, secondary charging of an opposite polarity is performed in the dark to make the charge layer 1/2 and make the charge density of the surface of the photoreceptor 1 1/2 that of negative following to which the color light images of the multichromatic original are radiated, whereby the electrostatic latent images of the corresponding multicolors are formed. In this way, copying of multicolors may be performed.
