Abstract: A plurality of photosensitive drums are disposed in a sheet transport direction so as to be in contact with a transfer belt and a transfer voltage for transferring toner images on the photosensitive drums onto a sheet transported by the transfer belt is applied thereto. A sensor for sensing a temperature or humidity in the working atmosphere of the image forming apparatus is provided; when a jam occurs, sheet transportation is ceased at a first stage to thereby enable the sheet in the jam to be removed; at a second stage subsequent thereto, transportation of the sheet is restarted; and a transport distance of the sheet is controlled based on a printing ratio of an image formed on the sheet.

Abstract: Disclosed is a semiconductor memory device which shortens an external access time when there is contention between an external access and an internal access. The semiconductor memory device includes an arbiter which receives a first entry signal for entering a first access mode (external access) and a second entry signal for entering a second access mode (internal access) and determines priority of the first and second access modes in accordance with an order of receipt of the first and second entry signals. The arbiter sequentially generates a first mode trigger signal corresponding to the first entry signal and a second mode trigger signal corresponding to the second entry signal in accordance with the determined priority. The arbiter executes the first access mode by priority over the second access mode when the arbiter is supplied with the first entry signal with a predetermined period after the second access mode has been determined to have priority.

Abstract: Gaskets in a storage element such as a battery or an electric double-layer capacitor are of a multiple-layer construction composed of a plurality of layers having holes of different inside dimensions. The upper-layer gaskets have holes with an inside diameter that is the same size as the outside diameter of the solid electrodes, and the lower-layer gaskets have holes with an inside diameter that is larger than the outside diameter of the solid electrodes. The electrodes are each closely fitted within the holes of the upper-layer gaskets and, as a result, are firmly secured and prevented from shifting. The fusion surface area of the upper-layer gaskets that are bonded together is increased. The existence of spaces for holding electrolytic solution between the inside diameter of the holes of the lower-layer gaskets and the outside diameter of the solid electrodes increases the amount of internal electrolytic solution that can be held.
