Abstract: Brightness profile data having a number of dimensions is extracted based on image data in a radial direction of an optical fiber, the brightness profile data representing features for each rotation angle of the optical fiber. Machine learning uses training data to create a prediction model that based on the brightness profile data determines a rotation angle of each pair of optical fibers is. The pair of optical fibers are rotated to the determined rotation angle and then fusion spliced. The training data indicates a correspondence relationship between the rotation angle of the optical fiber and brightness profile in the radial direction for each rotation angle of the optical fiber. The prediction model can determine a rotation angle of an arbitrary optical fiber based on brightness profile data of the arbitrary optical fiber.

Abstract: Brightness profile data are extracted based on side view image data of an optical fiber, machine learning is performed by using teacher data indicating a correspondence relationship between brightness profile in a radial direction of the optical fiber and a type of the optical fiber, the teacher data being created based on the brightness profile data, a classification model is created to be able to determine the type of the optical fiber for an arbitrary optical fiber based on the brightness profile data indicating brightness profile in the radial direction of the arbitrary optical fiber, and the type of the optical fiber is determined for each of a pair of optical fibers by using the classification model based on the brightness profile data that is extracted based on side view image data of the pair of optical fibers as a target. The pair of optical fibers are fusion-spliced based on a fusion condition that is set in accordance with a combination of respective determined types of the optical fibers.

Abstract: A communication terminal apparatus is connected to a single telephone line and is configured to be selectively connected either to a telephone set or to a facsimile machine. A pseudo ring back tone generator generates a repetitive pseudo ring back tone transmitted to a calling party in response to an incoming call. A pseudo ring signal generator generates a pseudo ring signal for driving a ringer of the telephone set to ring in response to the incoming call. A tone detector detects a CNG signal indicative that the incoming call is a facsimile. A controller controls at least the pseudo ring back tone generator and the pseudo ring signal generator. A table correlates a plurality of ring back tones with corresponding countries. If a ring back tone for a country meets a predetermined condition, the controller sets a predetermined pseudo ring back tone to the pseudo ring back tone generator.

Abstract: A sheet processing apparatus includes: a first folder to fold a sheet in a first folding direction relative to a given orientation of the sheet, a line of the fold defining a second edge of the sheet; a second folder to fold the folded sheet in a second folding direction perpendicular to the first folding direction; and a switcher, disposed between the first folder and the second folder, operable to switch a sheet conveyance direction of the sheet sent from the first folder and to align the sheet sent from the first folder, the switcher including the following, an aligning member arranged to face a first edge of the sheet, the first edge of the sheet being located relatively opposite to the second edge along the conveyance direction, the second edge not having a straight line shape, and a feeder to force the sheet in a given direction toward the aligning member so as to align the sheet in the sheet conveyance direction by contacting the first edge of the sheet against the aligning member.

Abstract: The image forming apparatus serves to raise a temperature of fusing section (22) only when an operational item received from operation panel section (3) is determined that an image printing is required. The image forming apparatus includes scanner section (1) for outputting an image data upon reading out an image on a text, image forming section (21) for forming an image on a predetermined print medium based on the image data, fusing section (22) for fusing thus formed image on the predetermined print medium at a prescribed fusing temperature, print requirement determination section (25) for determining as to whether or not an input of a specific operational item received from operation panel section (3) requires an image printing thereof, in which fusing temperature controlling section (23) serves to control a temperature rise of fusing section (22) on the basis of the determination by print requirement determination section (25) that the image printing is required.

Abstract: To provide an image forming system capable of displaying appropriately a plurality of apparatus statuses at low cost, the image forming system is structured upon connection of an independently operable printing apparatus with an independently operable scanning apparatus. The scanning apparatus stores in an NVRAM a status message of the printing apparatus corresponding to operable level information of the printing apparatus and displays the appropriate status message on a display unit upon selection among the plurality of status messages for indicating status of the printing apparatus based on the operable level information retrieved from the printing apparatus based on control by a main controller.

Abstract: A temperature controlling method is used to control a temperature of a heat roller for a fixing unit for use in a facsimile machine. A print engine prints a transmission report after information has been transmitted to a receiving end. An electric power is supplied to a heater in the heat concurrently with transmission of information to a receiving end so as to increase the temperature of the heat roller to a preheat temperature Tp. The heat roller is then maintained at the preheat temperature Tp during the transmission of the information to the receiving end. After the transmission of the information has been completed, the temperature of the heat roller is increased from the preheat temperature Tp to a fixing temperature Tf.
