Title: Optical fiber splicing device
Inventor: KANAYAMA KOICHI
IPC: G02B6/24
Filed: 1986-11-06
Abstract: PURPOSE:To accurately align the characteristic axes of polarization platen maintaining optical fibers (SPF) with each other by photodetecting light by a photodetecting element through a polarizing plate fitted to a polarizing plate rotating part, and rotating the polarizing plate and thus making an adjustment so that variation in the quantity of photodetection is maximum. CONSTITUTION:Light propagated in the 1st SPF 8 travels as linear polarized light because the polarizing direction of a linear polarized light source 7 is made coincident with the characteristic axis of the 1st SPF 8 previously, and the linear polarized light is outputted from the light projection end of the 1st SPF 8. While an electric signal from an output terminal 18 is monitored, the relative position between the rotary fixed part 12 of the SPFs and the light projection end fixation part 10 of the 1st SPF is so adjusted that the current light is maximum. Then a polarizer is rotated by a motor 21 and the rotary fixed part of the SPFs is rotated and adjusted so that the ratio of the maximum value Pmax and minimum value Pmin of the electric signal from the output terminal 18 is maximum. In this state, the polarizing direction of the linear polarized light from the 1st SPF 8 is aligned with the characteristic axis of the 2nd SPF 11.

Title: Recording head
Inventor: KIMOTO ISAO
IPC: B41J2/28
Filed: 1990-10-02
Abstract: PURPOSE:To perform printing operation at high speed by making the flux density of a permanent magnet variable corresponding to the displacement of a leaf spring at the time of the printing operation of a recording head and reducing the coil current necessary for the printing operation and shortening the rising time of the coil current. CONSTITUTION:A recording head is constituted of yokes 1, 2, a permanent magnet 3, a core 4 and the electromagnetic coil 5 wound around the core 4. A chip 20 is molded so that the vertical cross-section has a taper shape gradually widening from the leading end thereof to the mounting end part thereof to a leaf spring 6 in order to make the flux density of the permanent magnet variable and inserted in the through- hole 9 formed to the leaf spring 6. Therefore, the flux density passing through the chip 20 becomes large when the leaf spring 6 is not attracted to the permanent magnet 3 and becomes small when the leaf spring 6 is attracted to said magnet 3. Since the flux density of the permanent magnet 3 is made variable, the leaf spring 6 is attracted to the permanent magnet 3 by proper attraction force when the current of the coil is in a discontinuity state and, by allowing the relatively small current of the coil to flow, the leaf spring generates repulsive motion and printing operation is performed with rapid rising.
