摘要： An image forming device includes an image forming unit that includes an image carrier which carries an electrostatic latent image, a developing unit which forms a developing nip by contacting with the image carrier and develops the latent image by using toner, a transfer unit which forms a transferring nip by contacting with the image carrier and transfers a toner image onto a recording paper, and a first driving unit which rotates the image carrier, the developing unit and the transfer unit. The image forming device also includes a laser scanner unit that includes a polygon mirror and a second driving unit which rotates the polygon mirror. In addition, the image forming device includes a first control unit that starts driving of the second driving unit at a same time as a start of driving of the first driving unit, and a second control unit that executes a cleaning sequence process to return toner adhered on the transfer unit back to the image carrier during a period from the start of the driving of the second driving unit until a print permitting signal is output by the laser scanner unit.

摘要： A method for manufacturing sidewall contacts for a chalcogenide memory device is disclosed. A first conductive layer is initially deposited on top of a first oxide layer. The first conductive layer is then patterned and etched using well-known processes. Next, a second oxide layer is deposited on top of the first conductive layer and the first oxide layer. An opening is then etched into at least the first oxide layer such that a portion of the first conductive layer is exposed within the opening. The exposed portion of the first conductive layer is then removed from the opening such that the first conductive layer is flush with an inner surface or sidewall of the opening. After depositing a chalcogenide layer on top of the second oxide layer, filling the opening with chalcogenide, a second conductive layer is deposited on top of the chalcogenide layer.

摘要： A CCD color solid-state image pickup device has a plurality of light-receiving sections arranged in an array on the surface of a semiconductor substrate, and a vertical transfer path by way of which signal electric charges stored in electric charge storage sections of the respective light-receiving sections are read and transferred to a horizontal transfer path. In the image pickup device, the electric charge-storage section of each of the light-receiving sections has a plurality of electric charge storage layers which are provided in a depthwise direction of the semiconductor substrate with potential barriers interposed therebetween. Signal electric charges stored in the respective electric charge storage layers are read independently to the vertical transfer path.

摘要： The spacing member comprises: a spacing portion for spacing an electrophotographic photosensitive drum and a charging roller when the spacing member is attached to the process cartridge; a stopper portion for preventing a shutter member from retracting from a protection position for covering an exposure portion, when the spacing member is attached to the process cartridge; and a protective portion for covering a positioning portion, which positions the process cartridge in an apparatus body when the process cartridge is mounted in the apparatus body, when the spacing member is attached to the process cartridge. Thus, it is possible to reliably keep the spaced state between the photosensitive drum and the charging roller.

摘要： An apparatus and process for applying an electrical charge to a photoreceptor wherein a bias charge roll member is situated in contact or in close proximity with a surface of a member to be charged such as a photoreceptor. The bias charge roll member is supplied with an electrical bias having a variable voltage waveform onto which a DC bias is superimposed. The amount of DC bias is selected to set the signal voltage such that a minimally acceptable amount of AC corona is created sufficient for uniform photoreceptor charging while avoiding unnecessary excessive positive corona that causes excessive photoreceptor wear.
