Title: Capturing laser beam tracking error detecting method and device for inter-satellite optical communication
Inventor: WATANABE AKIRA
IPC: H04B10/079
Filed: 1998-10-08
Abstract: PROBLEM TO BE SOLVED: To provide a capturing laser beam tracking error detecting method and a device having no characteristic variation caused by a difference in the optical path length and a temperature of reference laser beams from plural light sources. SOLUTION: A capturing laser beam 101 is condensed by a light antenna 105 to be introduced to a two-dimensional sensor 113 through a mirror 106, a mirror 108 and a half mirror 109. A reference laser beam 100 sent out of a laser beam source 111 is phase-modulated by a hologram filter 112 to reach the two-dimensional sensor 113 to generate an interference fringe from a phase difference between both beams. The interference fringe is detected by the two-dimensional sensor 113 to be inputted to the signal processing part 104 as a detecting signal 103. The signal processing part 104 processes a pattern of the interference fringe by the detecting signal 103 to calculate an error in the arrival direction of the capturing lase beam 101 to drive and control the mirror 106 by sending a driving control signal 102 to a mirror control driving circuit 107.

Title: Panel type cooling device
Inventor: NAKAGAWA NAOHARU
IPC: F24F13/32
Filed: 1987-11-16
Abstract: PURPOSE:To realize an ideal temperature distribution which can keep the head cool and the feet warm by blowing off an uncooled air from the surface of a hollow panel and a cooled air from the end and introducing the air into a suction port on the opposite side of a blow-off port. CONSTITUTION:A suction port 10, which is equivalent to a blower 4, is installed to one end of a hollow panel 2 while a blow-off port 6 is installed to the upper surface of said hollow panel 2. At the same time, a blow-off port 8 is installed to the other side of the suction port 10 so that the air sucked-in from the suction port 10 may blow off from the blow off ports 6 and 8. When performing the aforesaid blowing-off operation, however, it is contrived that only the air discharged from the blow-off port 8 must be cooled by a heat exchanger 3. The air discharged from the blow-off ports 6 and 8 flow down in the direction of the suction port 10. Since the airflow discharged from the blow-off port 8 is cooled down by the heat exchanger 3, the air is cooler than the air discharged from the blow-off port 6, but the colder air supported by the air rising from the blow-off port 6, moves to a higher position and reaches the suction port 10. The portion directly over the hollow panel 2 is surrounded by a less cooler air discharged from the blow-off port 6. If is, therefore, possible to embody more comfortable cooling performance which can keep the head cool and the feet warm.
