Abstract: PURPOSE:To form a fine pattern by sufficiently reducing line width compared to that of a circuit pattern, through which at least large current is not passed, and to prevent the peeling of a conductor film, and improve reliability by forming a conductive layer consisting of a copper solder on a metallized layer, by which the circuit pattern is shaped on an aluminum nitride board. CONSTITUTION:A green sheet 10, on which conductor plate 12 is printed, is introduced into a baking furnace and baked, thus changing the green sheet 10 into a board 10A, then turning conductor paste 12 into metallized layers 12A. The metallized layer 12A is supplied with the tabular copper solder 14 of an alloy mainly comprising copper, and superposed and laminated on a required pattern, a circuit pattern for large current. When the board 10A, on which the solder 14 is laminated, is introduced into a heating furnace and heated, the solder 14 is melted, and changed into conductive layer 14A, in which the solder is bonded firmly and unified with the metallized layer 12A in the lower section of the wax material 14. A surface is plated with a nickel plated layer or a gold plated layer 16.

Title: Secondary transfer device
Inventor: ENOMOTO YOSHIHIRO
IPC: G03G15/16
Filed: 1997-11-29
Abstract: PROBLEM TO BE SOLVED: To provide a secondary transfer device by which an intermediate transfer body is not damage and deflective transfer is not caused even when secondary transfer is performed to paper sheet of smaller size than the paper sheet of maximum standard size. SOLUTION: A backup roll 14b is constituted by coating an insulating roll 14b1 molded of the foaming rubber of EPDM with a semiconductive thin layer tube 14b2 in which carbon black is dispersed, and adjusted so that its surface resistivity may be 10<7> to 10<11> Ω/square. Since a contact roll 14c is arranged at a position where the fluctuation width of total transfer current at the time of rotating the roll 14b is within 17 to 24 μA, the faulty transfer is prevented even when the surface resistivity of the roll 14b is uneven. By arranging the roll 14c at a position where the peripheral distances of the rolls 14b and 14a from a contact B between them are equal, a more excellent result is obtained.

Title: Method for optical demultiplexing
Inventor: DANIERU EI FUITSUSHIYUMAN
IPC: H04B10/152
Filed: 1993-12-20
Abstract: PURPOSE: To provide a wavelength multiplex light signal discriminating method for a wavelength multiplex light signal, having individual light signals modulated with specific frequencies respectively, among the multiplexed signals. CONSTITUTION: The modulation is imposed on the transmission side of the light signals, and the modulation frequencies are so selected that they are much lower than the low-band cut-off frequencies of all other pieces of information encoded onto the light signal. On the reception side of the multiplexed signals, the respective light signals are led to specific variable wavelength Fabry-Pe'rot optical filters 102-104 as functions of specific low frequency modulation, superposed on the individual light signals. Since the Fabry-Pe'rot filters 102-104 have performance competing with the frequencies of individual channels, the problems regarding wavelength drifts are eliminated.  Further, the Fabry-Pe'rot filters 102-104 have very narrow light transmission bands, so inter-channel crosstalk and noise level in a wavelength multiplexing optical system using signal discrimination technology are minimized.
