Title: Optcal wavelength multiplex transmission system
Inventor: ASHIKAWA SHIGEAKI
IPC: H04J14/00
Filed: 1986-07-23
Abstract: PURPOSE:To extend the range of transmission by setting a loss by a spectrum limit by an optical multiplexer/demultiplexer with respect to a short wavelength optical signal smaller than the loss with respect to a long wavelength optical signal in response to the transmission loss while keeping a photodetection level sufficiently high even with the optical signal of a short wavelength without using a new provision such as a repeater. CONSTITUTION:In sending an optical signal having a wavelength lambda1 from an optical multiplexer/demultiplexer at the sending side to an optical fiber, most of the spectrum of the optical signal passes through an optical filter for wavelength lambda and a high level optical signal is sent to an optical fiber. Most of the spectrum of the optical signal of wavelength lambda passes through the optical filter at the optical multiplexer/demultiplxer at the reception side and the signal is received by a photodetector while keeping nearly the signal level received by the optical multiplexer/demultiplexer. Thus, even if a large transmission loss is caused in the optical fiber because of a short wavelength, the part of the transmission loss is cancelled by the increment at the pass band by the optical multiplexer/demultiplexer and the photodetection level of the optical signal is kept to a value to be received by the photodetector.

Title: Wire dot matrix printer head
Inventor: SAGARA TAKEHIKO
IPC: B41J2/28
Filed: 1983-09-20
Abstract: PURPOSE:To suppress the deterioration of the operating characteristic at the all wire simultaneous drive time and to reduce the drive power by providing a branch path which always flow a magnetic flux by a permanent magnet. CONSTITUTION:A branching pole 21 is projected at the center of core group. When only one wire is driven, magnetic fluxes PHII1, PHII1P by a drive coil current cancel a magnetic flux PHIM by a permanent magnet, and an armature isolates from a core to perform a printing operation. The magnetic flux PHIMP by the permanent magnet of the branching pole decreases the efficiency of a permanent magnet, but the PHII1P can be sufficiently superposed, and the operating characteristics are excellent. When the all wires are then driven, the magnetic flux of the branching pole is superposed in the same direction with the magnetic flux of [all wire numberXPHII1P], becoming the worst rising condition, but the practically sufficient result can be obtained by suitably setting the sectional area of the branching pole.
