Filed: 1986-02-27
Abstract: PURPOSE:To save the quantity of water from the source of water supply and to effectively melt snow by controlling the operation of a water lifting pump based on a detected value of the temperature of water in a medium temperature tank and the operation of a circulating pump based on a detected value of a snow melting pipe embedding body to maintain the temperature of water to be supplied to the snow melting pipe to a predetermined value. CONSTITUTION:In a case where the temperature of water within a medium temperature tank 11 is less than a predetermined value and when a water lifting pump 4 operates, water W from the source of water supply having a temperature which is higher than the temperature of water within the medium temperature tank 11 is pumped up to a high-temperature tank 10. The water level is raised, and water having a high temperature flows into a medium temperature tank 11 through a water passing hole 13 from the high temperature-tank 10. In a case where the geothermic temperature of the snow melting pipe embedding body 2 becomes less than a predetermined value and a circulating pump 5 is actuated, water which has been sucked up from the medium temperature tank N is sent to a snow melting pipe 3 via a circulation pipe arrangement 17, and after melting snow piled up in the snow melting pipe embedding body 2, it is discharged into the upper portion of a low-temperature tank 12. When the liquid level of the low-temperature tank 2 rises up, a water flow passing through a weir 14 is produced in the medium temperature tank 11, and when it exceeds a preset value, water is drained out of the bottom portion of the low-temperature tank 12 via a flow- out pipe 19.

IPC: G05F1/10
Filed: 1979-04-09
Abstract: PURPOSE:To make it possible to detect disconnection of the external load at an early stage, by providing an isolator element such as a photo-coupler, etc. in the output circuit. CONSTITUTION:When a gate signal is provided to the gate G of a thyristor T1, a loop consisting of an AC power supply AC. S, the external load L1 and the thyristor T1 becomes the conducting state. Since a current does not flow into a capacitor C1, a resistor R1 and a photo-coupler PC1 in the above state, its logical output A' becomes ''1''. Although a current flows into the loop of AC.S PC1 R1 C1  L1 AC.S in case the thyristor T1 is in OFF state, the impedance of C1, R1 and PC1 is selected so that the load L1 cannot be driven by the current value i in this case, and on the other hand in order that the logical output A' of the output terminal a1 of the photo detector d2 can be ''0'' by a constant ray emitted by LED d1 of the photo-coupler PC1. Accordingly, when the thyristor T1 is not ignited, in case of A'=1, it can be detected that the loop is disconnected somewhere ahead.

Title: Data transmission/reception equipment
Inventor: OKADA KENJI
IPC: H04B10/07
Filed: 1998-02-09
Abstract: PROBLEM TO BE SOLVED: To provide data transmission/reception equipment with which the degradation of reception conditions or the waste of power can be suppressed by adjusting laser transmission output (light intensity) into optimum value corresponding to surrounding conditions such as the change of weather to attenuate laser light or the fluctuation of a transmission distance. SOLUTION: Data transmission/reception equipment 30 for mutually transmitting/receiving data through light between plural devices has a light intensity detecting means 42 for detecting the light intensity of optical data received from the other person, transmission data control means 37 for transmitting the detected light intensity from the other person to the other person as light intensity data, and light intensity adjusting means 32 and 41 for adjusting its own transmission light intensity corresponding to its own light intensity data received from the other person. Thus, when the light is considerably attenuated on a transmission line by the change of weather, for example, the degradation of reception is prevented by outputting the light of light intensity higher for that attenuation.  Besides, when the transmission distance is short, the waste of power is suppressed by outputting the light of low light intensity.
