Title: Temperature control for snow melting facilities
Inventor: ISHII JUN
IPC: E01H5/10
Filed: 1986-12-19
Abstract: PURPOSE:To control the temperature of a heat source for a snow melting facilities automatically at most suitable temperature in the snow melting facilities of electro thermal system by judging the weather from the outdoor temperature and judging conditions of operation at that weather and, furthermore, judging the suitable temperature under the condition of that operation. CONSTITUTION:The outdoor temperature is detected by an outdoor temperature sensor 4 and it is measured by a temperature measuring circuit 5. This measurement is made everytime a specified period signal is issued. The measured temperature is stored in temperature memories 31-3n. The data that is stored in those temperature memories is given cumulative calculation in an arithmetic circuit 7 everytime new data is added. The cumulative value is compared with the data that is stored in memory 7 for weather and operation conditions and there corresponding weather is judged, and conditions of operation such as snow melting, preheating, prevention of freezing, etc. are outputted. The outputted operation conditions are sent to a judgement circuit 8, and there they are compared with the data stored in a memory 2 for suitable temperature data to judge the most suitable temperature and the temperature of the heat source for the snow melting device is controlled automatically.

SOLUTION: When a plug opening switch OP is turned on by an user, a coil R of a latching relay is energized, a contact point is positioned on a position r, and a drain plug V is opened by a direct current motor M. When a plug closing switch CL is pushed in this condition, a coil S of a latching relay is energized, the contact point is changed over to a position s, and the direct current motor M is driven in a closing direction. In the opening condition, when water pressure is a constant value or less which is set in a pressure comparing section for the reason of suspension of water supply, an output of AND becomes signal 1 for a prescribed time, and thereby, the coil S of the latching relay is energized for a prescribed time through a transistor.

Abstract: PURPOSE:To obtain the title coated optical fiber with good workability and without two coating layers being mixed by providing the secondary coating layer on an optical fiber through the primary coating layer with the outer surface cured by UV rays and simultaneously curing both layers by UV rays. CONSTITUTION:A relatively low columnar partition chamber is formed between a primary coating layer forming device 2 and a secondary coating layer forming device 5.

The primary coating layer formed on the optical fiber 1 by the device 2 is irradiated by the thin-beam UV rays from the tubes 3 in the partition chamber and spot-cured, and only the surface is cured. At this time, the secondary coating layer agent on the hole of a nipple is not cured due to the presence of a douser 4. In addition, since the surface of the primary coating layer is cured, the infiltration of the primary coating layer material into the secondary coating layer material can be perfectly prevented.
