Abstract: PROBLEM TO BE SOLVED: To stably form a fine trench wiring structured copper wiring at low resistance in high reliability by a method wherein a copper material is buried in wiring trenches or holes formed in an organic interlayer film mainly comprising carbon so as to form conductive carbon layers between these copper material and the organic interlayer film. SOLUTION: A flattened underneath insulating film 2 is formed on the whole surface of a silicon substrate 1 so as to form an organic interlayer film 3 on the insulating film 2. Next, the specific regions of this interlayer film 3 composed of a fluorine added amorphous carbon film is fine processed to form wiring trenches 4. Next, the interlayer film 3 formed into the wiring trenches 4 is exposed in hydrogen plasma to be heat-treated at the temperature of about 200 deg.C. Resultantly, a conductive carbon layer 5 is formed on the upper part in the inner wall of the wiring trenches 4 and the upper parts of the interlayer film 3. Next, a Cu film 6 is deposited on the whole surface for covering the carbon layer 5 by CVD process. Successively, the unnecessary Cu film 6 and the carbon layer 5 on the interlayer film 3 are removed so as to form copper wirings 6a in the wiring trenches 4 through the intermediary of conductive carbon layers 5a.

Abstract: PROBLEM TO BE SOLVED: To provide a mechanism tensing various sheets drawn out from a rotary winding shaft in a driving device for taking in and out the sheets and a shutter with the driving device. SOLUTION: In the shutter, in which a sheet is wound up and opened onto a rotary winding shaft while the sheet is drawn out from the rotary winding shaft and which is closed by an electric motor 1 with a speed reducer, a transmission revolution body 36 (a movable wheel 38 and an output chain wheel 13) and a compression coil spring 37 (a revolving-torque storage body) are installed between the output shaft 8 of the electric motor 1 and the rotary winding shaft. Fluctuating revolving torque generated between the output shaft 8 and the rotary winding shaft can be stored in the compression coil spring 37 with the fluctuation difference of revolving torque generated between the output shaft 8 and the rotary winding shaft.  Accordingly, fluctuated load (such as the weight of the sheet under a tensed state between a normal opening state and a normal closing state) generated in the rotary winding shaft is absorbed and stored in the compression coil spring 37 with the fluctuation of the load, and the revolution of the output shaft 8 is transmitted to the rotary winding shaft while dynamically balancing a section between the output shaft 8 and the rotary winding shaft.

IPC: G03G15/00
Filed: 1995-07-04
Abstract: PROBLEM TO BE SOLVED: To increase processing speed by forming a loop for correcting the obliquely advancing state of a fed sheet in a high-speed carrying state. SOLUTION: The driving of a motor 18 is transmitted to a pair of carrying rollers 4 through an electromagnetic clutch 20, and transmitted to a pair of resist rollers 5 through an electromagnetic clutch 21. When a signal from a copying start key 22 is inputted, a CPU 19 drives a motor 18 on a high speed side. At such a time, the clutch 20 is turned on and the clutch 21 is turned off. When a resist sensor 15 detects the leading edge of the sheet S fed at high speed, the CPU 19 turns off the clutch 20 to stop the driving of the pair of carrying rollers 4 when the specified time elapses, and switches the motor 18 to a low speed side. The leading edge of the sheet S detected by the resist sensor 15 butts against the nip of the pair of resist rollers 5 and forms the specified amount of loop until the driving of the pair of carrying rollers 4 is stopped.
