Abstract: A semiconductor device includes a load element, a switching element, and a processor. The load element controls a temperature of the semiconductor device with an electric current supplied to the load element. The switching element switches between supply of an electric current to the load element and a cut-off of the supply. The processor controls the switching element. The processor controls the electric current to be supplied to the load element through the switching element so that the semiconductor device has a series of temperatures represented by a specific temperature profile.

Abstract: A data acquisition system includes an electronic device and a data acquisition terminal. The electronic device includes a data storage section and a first interface. The data acquisition terminal includes a terminal communication control section and a second interface to be connected to the first interface. The terminal communication control section instructs the electronic device to transmit data stored in the data storage section of the electronic device through the first interface. In response to an instruction from the terminal communication control section, the electronic device transmits the data stored in the data storage section to the data acquisition terminal by a predetermined communication scheme. The predetermined communication scheme is a communication scheme that uses a communication standard prescribed in a layer lower than an application layer in an open systems interconnection reference model.

Abstract: An image reading device includes: contact glass, a document reading section that reads a document loaded on the contact glass while a moving mechanism moves in a document reading direction, a reading control section that causes the document reading section to read the whole contact glass at a rate of once per a predefined number of times N1, a first contamination detection section, and a report section. The first contamination detection section detects, from image data of the whole contact glass obtained through the reading by the document reading section, contamination of the contact glass present in a region other than a region loaded with the document. The report section, upon detecting by the first contamination detection section the same contamination from all the pieces of image data obtained consecutively a predefined plural number of times M1, reports a user that the contamination is present on the contact glass.

Abstract: An image forming apparatus includes a communication device, a RAM, a job managing unit, and an external temporary memory area managing unit. The communication device performs data communication with an external user terminal apparatus. The job managing unit allocates a memory area required to execute a requested job and executes the requested job. When it is determined that the memory area can't be allocated in the RAM owing to shortage of a free area in the RAM, the external temporary memory area managing unit (a) identifies a user who issued a job execution request on the basis of user authentication, (b) identifies a user terminal apparatus corresponding the identified user, and (c) uses a storage device of the identified user terminal apparatus as a part or all of a memory area required to execute the requested job on the basis of data communication performed by the communication device.

Abstract: A job management device includes a display unit, an authenticating unit and a job display processing unit. The display unit displays information. The authenticating unit determines whether a user is previously authorized to use an image forming apparatus. The job display processing unit executes a job display processing by which the contents of print jobs to under execution and prior to execution among print jobs accepted by the image forming apparatus are arranged in an execution order and displayed on the display unit, the job display processing unit configured to, in the job display processing, identifiably display the contents of a print job inputted by an authenticated user who is determined by the authenticating unit to have prior authorization to use the image forming apparatus and unidentifiably display the contents of the print jobs inputted by users other than the authenticated user.

Abstract: An image forming apparatus has a printing function, a scanner function, and a control unit. In the printing function, a printed material acquired by recording image data included in a printing job received through a network on a recording paper is discharged. In the scanner function, the image data is acquired by reading a manuscript. The control unit judges whether the scanner function is in use for a long time (step A2) at the time of receiving the printing job (step A1). A printed material is discharged to an in-body discharge tray when it is judged that the scanner function is not in use for a long time (step A3). The printed material is discharged to a side discharge tray when it is judged that the scanner function is in use for a long time (step A5).

Abstract: A fixing device has: (a) an electromagnetic coil placed with a gap from a member of a magnetic material to be heated; a switching device that supplies electronic power to the electromagnetic coil; (b) a switching control unit that controls duty ratio for the switching device under a condition that a load voltage and a load current of the switching device are substantially zero when the switching device is turned on and/or off; (c) a shield member capable of being placed between the electromagnetic coil and the member to be heated to shield the member to be heated against a magnetic flux from the electromagnetic coil; and (d) a shield control unit that controls a shield amount of the shield member by moving either the shield member or both the electromagnetic coil and the member to be heated.

Abstract: An image forming apparatus includes: an image forming section; a discharger for discharging and guiding the copying paper to an outlet; and a controlling section for operating the image forming section, based on an image forming instruction from an operation section. A data fetching section fetches first image data on a plurality of pages and second image data on a plurality of pages. The operation section accepts, as the image forming instruction, a sheaf-unit sorting instruction which includes a predetermined number of copies of each of the first image data and second image data and sorting of the copies. The controlling section, based on the sheaf-unit sorting instruction executes, for the predetermined number of copies, an operation of guiding the first and second sheafs of copying paper, in sequence, to the outlet so that the first sheaf and second sheafs of copying paper are piled in order.
