Title: Hot/cold water mixing controller
Inventor: SHIBA BUNICHI
IPC: G05D23/13
Filed: 1992-02-12
Abstract: PURPOSE:To stabilize the operation of a mixing valve by changing the gain of a mixing valve control means when the temperature of the discharged hot water is close to the temperature of the cold water detected by a cold water temperature detection means. CONSTITUTION:When the temperature of the discharged hot water is close to the temperature of the supplied cold water, the set temperature TS is changed. Under such conditions, the temperature TC of the supplied cold water is detected by a cold water detection means 40 for execution of the temperature control. Then the difference is calculated as the deviation E between the temperature TS and the signal of a hot/ cold water mixture temperature detection means 15. Then a coefficient g (TC) of a driven amount of the mixing valve is calculated with the temperature TC defined as a variable and also a controlling amount f (E) is calculated based on the deviation E. The amount f (E) is multiplied by the coefficient g (TC) and a signal is outputted to a 1st driven amount setting means 42 based on the multiplied amount f (E). Then the current to be supplied to a 1st coil 26 is set to drive this coil. Thus it is possible to prevent the hunting of a mixing valve even in the summer season when the temperature of the cold water is close to the temperature of the discharged hot water and to stabilize the temperature of the hot/cold mixture water.

Filed: 1996-02-13
Abstract: PROBLEM TO BE SOLVED: To provide a heat treatment method for a metallic tube capable of removing the residual oil in a coiled tube at the time of heat treating a loose coil. SOLUTION: A pay-off table 1 and a receiving table 4 are rotated and the loose coil 9 on the pay-off table 1 is partly loosened to form the metallic tube 9c. While the metallic tube 9c is passed in an IH(induction heating furnace) 2 and a cooling vessel 3, the tube is taken up on the receiving table 4. In such a case, a purging gas is supplied from the other end 10b into the loose coil 9 via a purging gas supplying piping 8a, a rotary joint 7a, a conduit 11a and a joint 6a. Since the metallic tube 9c is heated to a high temp. in the IH 2, the residual oil sticking to the inside surface of the metallic tube 9c evaporates. The evaporated residual oil is pushed out by the purging gas and is discharged together with the purging gas from the one end 10a.  The waste gas is cooled by a heat exchanger 41, by which the oil-component in the waste gas is condensed and the purging gas and the coil-component are separated. The oil- component is recovered into a tank 42. As a result, the residual oil in the loose coil 9 is removed.

Abstract: PURPOSE:To progress metabolism activity of photosynthesis bacteria, etc., and to clean water by irradiating a cleaning area for >=2 hours a day at >=50 lux by a light source installed on or in the water in the night time and in a rainy day or cloudy day. CONSTITUTION:The living activities of the bacteria, such as photosynthesis bacteria, single-cell living things, such as water-blooms, diatoms, green algae, etc., living in water are vigorous and the cleaning of the water by the metabolism activities thereof progresses in the daytime when there is light. The cleaning does not, however, progress any longer when the irradiation quantity of light decreases. In addition, the photosynthesis bacteria, the single-cell living things, such as water-blooms, and the green algae, etc., do not make photosynthesis any longer and the oxygen is eventually not generated. The decomposition and removal of the pollutants are not progressed any more and the dissolved oxygen in the water is held decreased. The irradiation time of light is, thereupon, increased to progress the metabolism activities of these living things by the artificial illumination. As a result, the dissolved oxygen in the water is increased and the decomposition of the org. matter by aerobic bacteria is activated. The cleaning of the water is thus progressed.
