Title: Optical heterodyne signal selective reception system
Inventor: EMURA KATSUMI
IPC: H04B10/291
Filed: 1989-08-29
Abstract: PURPOSE:To realize an optical access node which extracts and receives necessary information from signal light and transmits the sent signal light to a next node as it is by providing a means which demodulates a signal to be selected and received from the voltage variation of one terminals of a semiconductor optical amplifier. CONSTITUTION:This system has the semiconductor optical amplifier 1, a local oscillation light source 2, an optical fiber coupler 3, a bias circuit 4, an amplifier 5, and a demodulating circuit 6. In this case, when the signal light 10 and local oscillation light 11 are sufficiently close in frequency, the terminal voltage 7 of the semiconductor optical amplifier 1 varies corresponding to the beats of the signal light 10 and local oscillation light 11. The variation of the terminal voltage 7 is amplified by the amplifier 5 and then demodulated by the demodulated circuit 6 by applying a demodulation system corresponding to the modulation system of the signal light 10 to extract the information from the signal light 10. Consequently, the optical access node is realized which extracts and receives the necessary information from the signal light 10 and received and transmits the sent signal light 10 to the next node as it is.

Title: Optical recorder
Inventor: KUWATA NAOKI
IPC: G11B7/09
Filed: 1984-10-23
Abstract: PURPOSE:To keep a gain ratio of preamplifying circuits constant against the variance of the quantity of received light of a photodetector to make a normal servo operation possible by providing a gain adjusting circuit to compensate the offset of preamplifying circuits due to the positional slippage of the divided photodetector. CONSTITUTION:A light 12 due to the knife edge method is irradiated onto a 2-divided photodetector 11. If this detector 11 is shifted downward, the gain of a gain adjusting circuit 14 is increased to equalize outputs of preamplifying circuits 13 and 13' because the output of the circuit 13 is larger than that of the circuit 13'. Thus, since the gain ratio of circuits 13 and 13' is kept constant even if the quantity of received light of the detector 11 is varied, the normal servo operation is always performed.

Title: Cooler
Inventor: NOMURA OSAMU
IPC: H05K5/06
Filed: 1996-08-07
Abstract: PROBLEM TO BE SOLVED: To suppress noise at the time of cooling by introducing the air, staying in an electronic apparatus, through a fan means to the lower part of the apparatus thence discharging the air downward. SOLUTION: A cooling fan 3 in a facsimile F is actuated to discharge the air through an opening 2b. The air flow A1 is deflected from a horizontal direction to a downward direction through a discharge duct 4 and eventually discharged from the duct end 4a at the lower part of the discharge duct 4. In this regard, noise generated from the cooling fan 3 is also deflected, along with the exhaust air flow, from the horizontal direction to the downward direction through the discharge duct 4 and eventually radiated from the duct end 4a at the lower part of the discharge duct 4. Since the radiating position and direction of noise can be isolated from general listeners of noise, noise generated from the cooling tan 3 can be reduced at the position of the noise listener.
