Title: Roll paper feeder
Inventor: ISHIDATE YOSHIYUKI
IPC: B65H23/08
Filed: 1983-03-30
Abstract: PURPOSE:To feed paper steadily by providing a roll paper pushing member and a shaft pushing member connected thereto for preventing the excessive feeding of the paper when the paper feeding is stopped. CONSTITUTION:When a feed roll 3 is operated by an external signal, a shaft 5 is rotated with a board member 11 pressing a bearing 6, and a roll paper 1 is successively unrolled and fed passing between rolls 3 and 4. When a conveying means, the roll 3, is stopped, the shaft 5 is further rotated by inertia force to send out the paper 1, but such inertia energy is absorbed by the frictional resistance between a shaft pushing member 23 and a roll 25, and the shaft 5 is stopped without fail almost at the same time with the roll 3. When the diameter of the paper 1 is small, the inertia force is small, and there is a fear to feed the paper excessively due to the over-revolution of the shaft 5. But, a roll paper pushing member 21 is rotated round a bar member 22 to be risen, and accordingly, the shaft pushing member 23 is risen to push the roll 25 stronger.

Title: Printer
Inventor: OKANO NOBUAKI
IPC: B41J13/10
Filed: 1980-04-24
Abstract: PURPOSE: To facilitate the insertion of a blank sheet and to accurately determine the starting position of type printing, by detecting the end of an inserted type-printing blank sheet, and carrying a platen and a pinch roller in accordance with the detection, in a printer such as a serial printer.  
     CONSTITUTION: A type-printing blank sheet 18a, having a predetermined length, is inserted into a second-sheet guide 4. When the front end of the blank sheet 18a reaches a detector 17, a platen 2 and a pinch roller 5 move along a direction apart from a type printing head 1 in accordance with the detection of the arrival. At the same time, a sheet feed roller 5 is rotated anticlockwise. The blank sheet 18a concurrently butts against the stopper part 14 of a guide 3, and settled in the position. The platen 2 and the pinch roller 8 is returned after a certain period by a timer cooperating with the detector 17. When the final end of the blank sheet 18a passes over the detector 17 and the begining position of type printing corresponds to a type printing part, the rotation of the sheet feed roller 5 is switched to clockwise. Consequently, the type printing operation is performed, while feeding the  blank sheet 18a toward the guide 4.

Abstract: PURPOSE:To reproduce correct digital data by operating exclusive OR between data, which is generated by slicing read data and is not delayed, and data which is generated similarly and is delayed and latching delayed data synchronously with the output of this OR. CONSTITUTION:When a clock signal is supplied to a clock input terminal 17 and digital data including glitch in the polarity inversion part is generated from a comparator 12, D-FF circuits 15 and 16 latch data by the rise of the clock signal, and delayed data is outputted from an output terminal Q of the circuit 16. Output data of the circuit 16 is latched synchronously with the rise of output data from an EXOR circuit 8 by a D-FF circuit 19. Therefore, the polarity inversion point of time of output data of the circuit 19 is synchronized with the first polarity variance of glitch of data outputted from the comparator 12, and digital data where glitch is removed is supplied to a demodulating reproducing system through an output terminal 10. Thus, correct data is reproduced with simple constitution.

Abstract: PURPOSE:To improve the reliability by a method wherein a photosensitive resin film whose parts corresponding to through-holes are removed and which has a specific thickness is formed and wiring patterns composed of thin films and connected to the through-holes are formed on the photosensitive resin film. CONSTITUTION:A photosensitive resin film 4 having a thickness not larger than 3mum is formed on the main surface of a ceramic substrate 1 having through-holes 3. Only the parts of the photosensitive resin film 4 corresponding to the through-holes 3 are removed. Wiring patterns 2 connected to the through- holes 3 are composed of thin films on the surface of the photosensitive resin film 4. As defective parts such as recesses and crackings on the main surface of the ceramic substrate 1 are covered with the photosensitive resin film 4, the number of the defective parts which exist between the wirings when the wiring patterns 2 are formed by forming the thin film on the photosensitive resin film 4 and etching the thin film to remove its unnecessary parts can be reduced. With this constitution, electrical insulating properties between the wirings can be maintained and harmful influence upon an enclosed IC can be avoided, so that the reliability of the package can be improved.
