Abstract: PURPOSE:To make it possible to perform safe, highly reliable liquid level detection, by using an optical sensor. CONSTITUTION:Light is coupled into a light sending optical faber 1 from a light source 12 through a lens system 13. The light passes through the optical fiber 1 and is projected into a space from an end surface 1a of the optical fiber 1. The light is reflected by a reflecting surface 7a and received by an end surface 2a of a light receiving optical fiber. The light passes through the optical fiber 2 and is converted into an electrical quantity by a light receiving element 14. Then it is amplified to a desired level by an amplifier 15 and supplied to a comparator 16. In the comparator 16, the output of the amplifier is compared with the desired reference voltage, which is imparted by a variable resistor 17. Then, the position of a float, which is provided with the reflecting surface 7a and floated on the surface of a liquid to be measured so that the float can be moved freely, can be detected. Namely, whether the liquid level is higher or lower than the specified position can be found.

Title: Defrosting control device of heat pump type air conditioner
Inventor: OGATA HIDEO
IPC: F24F11/02
Filed: 1984-01-11
Abstract: PURPOSE:To check the room temperature drop during defrosting by a constitution wherein the defrosting operation is started at the room temperature, which is arrived by raising the set temperature by the predetermined temperature and performing the heating operation through the differential being made smaller than the predetermined temperature. CONSTITUTION:When the defrosting signal B is outputted from a defrosting signal generator circuit 5, the set temperature 2 is raised by the predetermined temperature (t) and the differential 4 is changed to B', which is smaller than the predetermined temperature (t). Accordingly, the compressor ON-OFF signal A sent from a comparator 3 goes to the high level. A defrosting operation signal C, which passes through a flip-flop 8 and an AND circuit 9, remains its low level, resulting in remaining a relay 14 in the OFF state and consequently running on the heating operation. When the elevated set temperature is reached, the signal A goes to the low level, resulting in the defrosting operation signal C reaching the high level and starting the defrosting operation. Thus, because the defrosting is performed after the room temperature is elevated, the difference between the room temperature and the set temperature can be made smaller.
