摘要： A cold water supply system includes an agitator tank in a cold water supply tank for receiving the cold water from a refrigerating units and a bypass pipe line for directing a calculated amount of return water from the load into the agitator tank. A temperature sensor for sensing the return water temperature is provided and another temperature sensor for sensing the refrigeration unit outlet temperature is provided for controlling regulating means in accordance with the sensed temperatures for automatically regulating the cold water temperature supplied into the agitator tank to a predetermined temperature.

摘要： A display board illuminating device includes a light guide plate arranged to face the back of a display board and a light source disposed to face the side end of the light guide plate. The side end of the light guide plate is inclined toward the center of the light guide plate in the direction of the display board. By this configuration an angle of an optical axis refracted at the surface of the side end and incident into the light guide plate with respect to a main surface of the light guide plate, so that the whole area of the display board is illuminated efficiently.
