摘要： In a construction wherein at the start of fixing, a pressure belt is brought into contact with a fixing roller at uniform timing, it has sometimes been the case that the temperature of the pressure belt at a point of time whereat the fixing is started does not become a desired temperature but faulty fixing occurs. The timing for bringing the pressure belt into contact with the fixing roller at the start of fixing is changed in accordance with the detected temperature of the pressure belt. By such a construction, faulty fixing can be prevented from occurring.

摘要： In a sheet conveyance system in which a plurality of apparatuses each including a communication unit with a plurality of communication channels are connected, and a sheet is conveyed between the apparatuses, each of the plurality of communication channels can be switched between a transmission mode and a reception mode. When a plurality of transmission channels are set by channel assignment, communication can be executed by giving a priority to each transmission destination. If transmission data are accumulated in an apparatus, and they include data for a transmission destination with a higher priority over the current data transmission destination, the number of transmission channels is increased, and the priority is raised.

摘要： In an image forming apparatus having a discrimination mechanism that identifies an input document image as a color image or a monochrome image and an area recognition mechanism that recognizes a plurality of different areas contained in the document image, the apparatus applies the optimum color image forming mode even if the document is identified as a color image and forms an image. The user is permitted to select either a first color image forming mode that uses recording agents of m colors (where m is a natural number equal to or greater than 4) or a second color image forming mode that uses recording agents of n colors (where n is a natural number equal to or greater than m+1) as a color image forming mode applied to at least one of the areas recognized by the area recognition mechanism. If the input document image is identified as a color image, the apparatus applies the selected color image forming mode to at least one of the areas recognized by the area recognition mechanism and forms an image.

摘要： A memory transistor and a select transistor are disposed side by side on a semiconductor substrate between source/drain diffusion layers thereof, with an intermediate diffusion layer interposed therebetween. The memory transistor includes: a gate insulating film having such a thickness as to allow tunneling current to pass therethrough; a floating gate electrode; an interelectrode insulating film; and a control gate electrode. The select transistor includes a gate insulating film and a select gate electrode. Tunneling current, allowing electrons to pass through the gate insulating film under the floating gate electrode, is utilized during the removal and injection of electrons from/into the floating gate electrode. As a result, higher reliability can be attained and rewriting can be performed at a lower voltage. Also, since the select transistor is provided, reading can also be performed at a lower voltage. Improvement of reliability and rewrite and read operations at respective lower voltages are realized for a nonvolatile semiconductor memory device, in which a memory cell includes a floating gate electrode and a control gate electrode.

摘要： When a control gate electrode 7 is processed using a control gate electrode processing mask 8, the control gate electrode 7 in a region where the floating gate electrode 4 has been removed is partially left. Because of the presence of the left control gate electrode 7, the gate electrode interlayer insulating film 6 and gate insulating film 3 below the control gate electrode 7 are not dug in the region where the floating gate electrode 4 has been removed. Therefore, when the floating gate electrode 4 is removed, the semiconductor substrate is not dug. In this way, since the semiconductor substrate 1 is not dug, the semiconductor memory device can be manufactured stably and precisely.
