Abstract: A group-three facsimile machine answers a call by transmitting at least one non-standard tone, before transmitting the standard called terminal identification tone or modulated answer tone. The non-standard tone invites the calling facsimile machine to modify the usual group-three handshaking procedure in such a way that under certain conditions, the procedure can be shortened. Among the many possible modifications are immediate transmission of a password, immediate transmission of training signals if the calling facsimile machine already knows the capabilities of the called facsimile machine, and immediate disconnection if the non-standard tone indicates that the called facsimile machine lacks a necessary capability.

Abstract: A magnetic field source movable type phantom head has a vessel filled with physiologic saline. The vessel preferably has an inner contour corresponding to an outer contour of a cerebrum of a patient to be tested. An electrode support tube has electrodes at one end. The electrodes are arranged within the vessel and movable at least in a vertical direction toward a center of the vessel as guided by a guiding and fixing device which guides the electrode support tube in a liquid tight fashion and fixes at a predetermined position. A position of the electrode support tube is measured to determine a position of the magnetic field source in the vessel.

Abstract: A new and improved electrical socket contact has good structural integrity and a design which forestalls the possibility of having a male contact inadvertently inserted behind the spring contact. This is accomplished first through an overall design in which a spring contact section is completely surrounded by four side walls and a back wall, the walls having a generally box-like configuration. The spring section has a pair of overlying spring members, the innermost member having an overlying spring assist portion. The portion of the innermost spring portion nearest the socket opening is protected by a curved end portion of an overlying wall which also acts to protect the spring section. The socket contact of the present invention is formed from a single piece of flat material and is formed through several folding steps to achieve the final construction. The socket contact formed enables a high reliability very miniaturized contact.

Abstract: An image forming apparatus has an upper print head unit and a lower print head unit that print plural printing areas in order on a printing medium. The image forming apparatus defers printing, as long as the image data corresponding to the areas to be printed are not transferred from a host apparatus, and begins printing when the image data are transferred from the host apparatus. The image forming apparatus can thus print an unfixed length of continuous image without monopolizing the host apparatus.

Abstract: An ink-jet printing apparatus, having a first printing head at an upper position with respect to a cloth-conveying direction and a second printing head at a lower position with respect to the cloth-conveying direction, scans the printing heads in a direction orthogonal to the cloth-conveying direction. An image printed by the first printing head is complemented by the second printing head. If a stop of printing is instructed during the printing by the first printing head, the printing by the first printing head is stopped, and printing by the second printing head is continued until the position of the image printed by the first printing head is printed by the second printing head. In this manner, a printed image completed to the end of the image can be obtained.

Abstract: When an magnified and synthesized image is finally printed on a printing medium based on an original image and a character font data, linear magnifying processing is executed with the aid of a software on the host computer side for the original image optically read by a scanner. In addition, vector magnifying processing is executed for font data likewise with the aid of a software, and moreover, synthesizing processing is executed for the font data. At this time, forming processing such as edge emphasizing or the like can be executed after completion of the vector magnifying processing. Synthesizing data are additionally magnified in a printer with the aid of a hardware, and subsequently, the magnified and synthesized image is outputted to the printer for performing a printing operation by the latter. An magnifying rate applicable to the host computer and the printer can be determined such that productivity of the image forming system is maximized.
