Title: Method and device for assembling optical connector
Inventor: NAKAMURA SHINJI
IPC: G02B6/38
Filed: 1987-06-26
Abstract: PURPOSE:To reduce the cost of ferrule production by packing a fixing agent into a ferrule in the state of inserting an optical fiber to the ferrule and curing the fixing agent while repeating a centering operation so that the fine hole of the ferrule is formed to a single hole diameter. CONSTITUTION:The fixing agent 3 is packed into the clearance of the fine hole of the optical connector having the fine hole which allows the free insertion of the optical fiber 1 while the ferrule 2 is held inserted into the connector. The optical fiber and the ferrule are held to a central position supporting device for centering to align the axial centers thereof. The mis-alignment between the optical fiber 1 and the ferrule 2 is then detected and a means for correcting the axial centers is finely adjusted to correct the mis-alignment. The fixing agent 3 is thereafter heated up to the curing temp. thereof. The correction of the mis-alignment is further repeatedly executed during the heating process and after the fixing agent 3 is heated for the prescribed time at the curing temp., the heating is stopped. The optical fiber 1 is thus fixed to the ferule 2. The ferrule can be thereby formed to one kind of the diameter of the fine hole and since the eccentricity of the fine hole is adjustable by the centering stage, the cost of the ferrule production is reduced.

Title: Pressure fixing unit
Inventor: NAKAI AKIRA
IPC: G03G15/20
Filed: 1979-12-07
Abstract: PURPOSE: To realize a use of a continuous paper, by securing such constitution in that the oblique shift of the paper occurring in the course of the paper fixing treatment is detected with a sensor and then the oblique shift of the paper is corrected automatically.  
     CONSTITUTION: When the recording paper 6 shifts obliquely to the left side in the figure, the sensor 24 actuates the motor 33. With actuation of the motor 33, the support frame 27 shifts left by the lead screw 32. As a result, the part having a larger diameter of the pressure roller 26 touches the right edge of the recording paper 6, and thus the shifting speed is increased at the right edge of the paper 6. Accordingly, the paper 6 shifts obliquely to the right side, and thus a correction is started for the oblique shift of the paper. In the right oblique shift of the paper 6, the sensor 24 actuates the motor 33'. Thus the paper 6 shifts left in the same process as the left shift of the paper 6, and the correction is given to the oblique shift of the paper. The motor then stops when the output signal of the sensor 24 becomes zero to complete the correction for the oblique shift of the paper. Thus the continuous paper is used.
