Abstract: A power source terminal and a ground terminal for a semiconductor integrated circuit are connected to a conductor pattern through a capacitor. The conductor pattern is connected, through a filter, to a plane conductor connected to neither a ground plane nor a power source plane. Thus, a common mode noise arising from between the power source and the ground is caused to flow into the plane conductor. This reduces the common mode noise flowing in the ground and the power source of the printed wiring board, which relatively act as antennas.

Abstract: An image processing method of forming images of data onto a plurality of recording media each having an obverse surface and a reverse surface is disclosed. This method has a recognizing step of recognizing a delimiter of the data in document data and a recognizing step of, in the case where the delimiter of the data is recognized in the recognizing step when an image process is executed so as to form the image onto the obverse surface of a predetermined recording medium, recognizing an instruction showing either a mode to continue the image forming operation to the reverse surface of the recording medium or a mode to exchange the recording medium and continue the image forming operation from the obverse surface of another recording medium.

Abstract: A distance/defocus device has a plurality of areas in an observing frame, and time sequentially determines the distance to an object or an amount of defocus for each area by performing a correlation calculation while shifting images of the object with respect to each other. The calculation time can be reduced by determining a shift range of the correlation calculation for subsequent areas on the basis of the result of the correlation calculation for a previous, predetermined area.

Abstract: A developing apparatus includes an accommodating container for containing a developer, the container having an opening; a developing container having an opening to which the developer is supplied from the opening of the accommodating container, wherein a developer carrying member for carrying the developer is provided at a developing position; and an elastic sealing member, provided adjacent a longitudinal end of the accommodating container between the accommodating container and the developing container, for preventing to the leakage of the developer. The accommodating container and the the developing container are welded together along the longitudinal direction, and the welded portion includes portions that overlap ends of the elastic sealing member which end in the longitudinal direction.

Abstract: The present invention pertains to a charging member which is energized to charge a chargeable member by contact-electrification and which comprises a conductive elastic layer having a surface layer containing a polymer having a main chain containing a structural unit of the following formula:--O--(CH.sub.2).sub.n --O--CO--wherein n is an integer of from 4 to 10.With stable charging properties, the charging member of the present invention has relatively uniform surface resistance, little dependency on the environmental conditions, and decreased contamination of photosensitive bodies and the like.

Abstract: An image processor performs a processing method which includes (a) reading out hierarchical-encoded binary image data stored in a storing medium, (b) decoding the binary image data read out in the step (a), (c) performing a multi-level generation to the binary image data decoded in the step (b), and (d) causing a display device to display an image, on the basis of the data decoded in the step (b) or the data multi-level generation processed in the step (c), wherein, in a case of causing the display device to display the image on the basis of data having a resolution which is higher than the resolution of the display device, the image is displayed in the step (d) after the binary image data is multi-level generation processed in the step (c), thereby preventing deterioration of the image when the image data stored in the storing medium is output.

Abstract: In a private branch exchange system which includes a private branch exchange accommodating a plurality of line wires and extensions for switching lines between the two, and telephones, which are usable in the event of a power failure, connected to the extensions, the line wires and the power-failure telephones are connected when power feed to the private branch exchange is no longer performed owing to a power failure or the like. When power feed is restored, the call status of the power-failure telephone is monitored and, if it is found that a call is in progress.

Abstract: An electrophotographic photosensitive member comprises a conductive support and provided thereon a photosensitive layer, interposing an intermediate layer between them. The intermediate layer contains a polyether polyamide.
