Filed: 1998-10-19
Abstract: PROBLEM TO BE SOLVED: To reduce power source voltage and to attain low power consumption without accompanying decline in the quality of an optical output waveform by equipping a current mirror circuit, which folds back an output current of a differential amplifier. SOLUTION: A conventional laser diode was connected directly to a differential amplifier connected to a differential amplifier current source, but a current mirror 8a in this case folds back a modulation current generated at a differential amplifier 2 and outputs it to a laser diode 5. Therefore, a sufficient voltage Vce which subtracts just a laser diode forward voltage Vf from a power source voltage Vee is applied between a collector and an emitter of a transistor at a final step inside the current mirror 8a. Thus, the final step transistor can be operated at a high speed, a power source voltage is lowered without causing decline in quality of an optical output waveform, and low power consumption can be attained.

Title: Slave station entry method for optical transmission system
Inventor: ITO KATSUJI
IPC: H04B10/29
Filed: 1993-11-26
Abstract: PURPOSE:To prevent the impossibility of communication due to optical beat to perform stable optical communication by permitting the entry to a system of a new slave station in accordance with the occurrence of optical beat of an optical signal at the time of originating a call. CONSTITUTION:When the.new slave station is connected to an optical cable, a master station requests all the stations in the system to simultaneously originate calls in a prescribed time. When calls are originated from all the stations, the master station takes in optical signals for calls by an O/E 16, and the occurrence of optical beat is detected by a CPU 11. When optical beat doesn't occur, the entry or the new slave station is permitted. If optical beat occurs, the entry is inhibited because communication is impossible, The new slave station receives calls from all the stations and takes in optical signals for calls by an O/E 26, and the occurrence of optical beat is detected by a beat detecting circuit 51. If it occurs, a driving current control circuit 52 controls a driving circuit 28a in accordance with this occurrence, and supply current setting of an LD 28b in its own station is changed to finely adjust the oscillation signal wavelength, thereby performing the avoiding operation for prevention of the occurrence of optical beat. Thus, the impossibility of communication due to optical beat is prevented.

Abstract: PURPOSE:To obtain a particle analyzer in which the fluorescent image of an excited particle is picked up by means of a video camera from the front side of the particle by a constitution wherein the fluorescent light emitted from the excited particle is received by the image pick up means for a predetermined time through a shutter means. CONSTITUTION:Light emitted from a laser light source 2 enters into a flow cell 1 and impinges on a particle to be inspected which is thereby excited to emit fluorescent light. The fluorescent light passes through an objective lens 5 and focused, as a fluorescent image, on the input plane of an intensified video camera 3. An unblurred fluorescent image is obtained from the camera 3 by opening the gate momentarily when the particle is present in the area irradiated with the exciting light. The faint fluorescent image focused on the input plane of the camera 3 is intensified by several thousands to several tens of thousand times by means of an image intensifier before being picked up. The fluorescent image thus picked up is then processed by an image processor 7 where the fluorescent emission intensity, localization of fluorescent emission part, etc. are analyzed.
