Title: Transmission abnormality processing device for multiplex
Inventor: SAKAGAMI ATSUSHI
IPC: H04J3/24
Filed: 1985-03-28
Abstract: PURPOSE:To control a load by a power source with an appropriate mode in an appropriate state in the case of abnormal multiplex transmission by switching the power source mode of the load based upon the normal/abnormal state of the multiplex transmission and controlling the above stated load by a prescribed mode when it is abnormal. CONSTITUTION:In a normal state, a head light 13 receives a potential from a battery power source line BATT and is controlled by the on-off operation of a transistor 19 actuated according to a control signal from a demodulator 15. When a data line DATA is always at a ground potential state or always at a power source potential state, a transistor 39 is turned off and the potential of J4 at a drain side is controlled by the potential of an ignition power source line IGN. Therefore, while the potential of the ignition power line IGN is at a high level by turning on an ignition key switch, the head light 13 is lightened. Also, when the potential of the ignition power source line IGN becomes a low (zero) level by the turning off of the ignition key switch, the transistor 19 is turned off and so the head light 13 is turned off.

Title: Semiconductor laser device
Inventor: OKUDA HAJIME
IPC: H01S5/14
Filed: 1984-03-31
Abstract: PURPOSE:To widen the oscillation line width of a single axial mode, and to lower coherence by returning reflected beams from a predetermined position to a distributed feedback type semiconductor laser (a DFB laser) displaying single axial mode oscillation. CONSTITUTION:When currents are injected to an N side electrode 17 from a P side electrode 16, a DFB laser 10 is brought to the state of oscillation, one part of laser beams projected from the DFB laser 10 is changed into parallel beams by a lens 30 and introduced to a reflecting mirror 20, and one part of the introduced beams is returned to the DFB laser 10 again from the lens 30. A mode jump or multimode oscillation during a DFB mode is not observed, but competition between an external resonator mode and the DFB mode is observed. The state of an oscillation mode changes in the length of external cavity length L. The line width of a single axial mode can be widened by properly setting length L. A laser of wide oscillation spectrum width has excellent reproducibility and controllability, in which noises are lowered remarkably when the laser is applied to optical fiber communication.
