Title: Method and apparatus for diffusing stagnant water
Inventor: TAKARADA MORIYASU
IPC: E02B3/02
Filed: 1994-11-15
Abstract: PURPOSE: To improve water quality, by directing water-flow to a stagnant zone of water, by producing vortical flow, and by mixing and diffusing stagnant water at a lake, a marsh, a bay or the like. CONSTITUTION: A first flexible bank 5 for directing water-flow, which deflects a tide 3 and produces the water-flow toward the inside of a bay 1, is laid outside the bay 1. A second flexible bank 7 for directing the water-flow, which again deflects deflected water flow 6 produced inside the bay 1, toward a stagnant zone 4, is laid inside the bay 1. Furthermore, weirs 9 for allowing deflected water flow 8 to overflow are laid at the outside part of the stagnant zone 4. In this way, almost vertically vortical flow is produced in the zone 4 of water by the deflected water-flow 8 overflowing the weires 9, which has kinetic energy and potential energy sufficiently large, and stagnant water is diffused sufficiently uniformly by mixing the deflected water-flow 8 overflowing.  In such a state that the banks 5, 7 and the weirs 9 are installed, pressurized air is supplied to each cylindrical body 11, and the cylindrical bodies 11 are expanded and can be floated. As a result, a curtain 12 functions as a dam effectively damming the water-flow ranging from the cylindrical body 11 to the bottom of the water, or as the bank changing the direction of the water-flow.

Title: Finned heat exchanger
Inventor: KOMATSUBARA KOSUKE
IPC: F28F19/00
Filed: 1984-12-27
Abstract: PURPOSE:To prevent the growth of frost at the leading edges of the fins and prevent the reduction of heat exchanging amount by a method wherein multiple cut-out sections are arranged continuously on the fins located at the upstream side of airflow through heat transfer tubes in parallel to the arranging direction of the steps of heat transfer tubes. CONSTITUTION:The cut-out sections 7 are provided near the leading edge 3 of a fin, therefore, the part of the sections will never be frosted and the growth of frost on the leading edge 3 of the fin may be prevented. Accordingly, clogging between the plate fins may be precluded and the surface of the fin is frosted uniformly whereby the operating time of a heat pump is elongated remarkably. On the other hand, mixing effect of flow is generated between neighboring fins at the cut-out sections, therefore, the heat transfer coefficient of the surface of the fin may be improved and heat exchange of the same degree as the heat exchanger having no cut-out section 7 may be effected since the reduction of the surface area of the fin due to the cut-out section 7 is supplemented by the improvement of the heat transfer coefficient.

Title: Control system for system linking photovoltaic power generating device
Inventor: TOKUDA KENSHO
IPC: G05F1/67
Filed: 1986-11-26
Abstract: PURPOSE:To ensure the highly efficient working of the titled control system by detecting the element temperature and applying correction to the reference voltage for control so that a solar battery works at its maximum power output point. CONSTITUTION:A temperature sensor 10 for solar battery element is set approximate to a solar battery element 1 and the output signal is supplied to a voltage-correction value exchanging circuit 11. The output signal received from the circuit 11 is compared with the control reference signal received from a DC voltage setting means 12 and then with the output signal of a DC voltage detecting circuit 8. The difference voltage signal obtained through said comparison is supplied to a DC voltage control circuit 13. Then, a gate pulse generating circuit 14 produces a gate pulse to the switching element of a PWM inverter 4 by the output signal of the circuit 13. Thus, the correction signal (e) received from the circuit 11 is subtracted from the reference value for control of the inverter 4 for reduction of the inverter control reference voltage value. This reference voltage level is increased as the temperature drops for correction. As a result, the solar battery is always operated at its maximum power output point regardless of the temperature change of the element 1.
