Abstract: PURPOSE:To obtain a solar heat utilizing system which needs no conveying power and improves fitness to a building, by a method wherein circular opening parts are formed in the upper and the lower part of a heat insulating partition plate in a heat accumulating tank, a space between the partition plate and the heat collecting plate forms a heat collecting plate part, and a film having shape retention and size larger than the lower opening part is movably situated to the lower opening and on the heat collection part side. CONSTITUTION:When solar radiation is started, heat is collected by means of a heat collection plate 23. In this case, water in a heat collection part 27 is increased in temperature by means of heat from the heat collection plate 23, and its specific gravity is decreased to a value lower than that of water in a heat accumulating tank 24 to produce a pressure difference, owing to which a flow flowing along the heat collection part 27 from below to above due to convection is generated. A flow moved to a position above the heat collection part 27 passes a plurality of holes 28, formed in a plate 29, from below to above, and forcibly opens a film 30, placed above the holes 28, and flows through an opening part 26 to the heat accumulating tank 24. Meanwhile, the flow of water in the vicinity of a lower opening part 26 produces a flow from an upper opening part 26 to the heat accumulating part 24. The flow passes, in a similar way described above, a plurality of holes 28 formed in a plate 29 from below to above, and forcibly opens a film 30 placed above the holes 28 and flow to the heat collection part 27.

Title: Output control system for optical repeater
Inventor: YAMAMOTO SHU
IPC: H04B10/079
Filed: 1989-11-22
Abstract: PURPOSE:To stabilize the transmission characteristics of incoming and outgoing lines even at the time of a fault such as the destruction of an optical fiber and to enable the monitor and control of a repeater by controlling the repeater group of the incoming line, as well by using a control signal for outgoing line to control the repeater group arranged at the outgoing optical fiber. CONSTITUTION:When a fault point 6 is generated, a line number signal and the control signal are not present on the incoming optical amplifier 10b and therefore, an optical output is made instable. According to control from an S station, an optical shutter 17a is opened through an optical shutter control circuit 15a and the output of the outgoing optical amplifier 10a is inputted to the incoming repeater 10b. By setting the frequency of a control signal 7a so as to be the incoming line the same as the outgoing line, the control signal 7a passes through a photodetector 12b and a narrow band filter 13b and can control the output of the incoming amplifier 10b similarly to the outgoing amplifier 10a. Therefore, when the fault is generated, an optical signal including the control signal 7a controls a repeater group 4 in the feedback line of the incoming optical fiber 2, as well and the transmission characteristic of the incoming feedback line is stabilized.
