Title: Optical detecting device
Inventor: ADACHI TETSUO
IPC: G08B17/107
Filed: 1984-06-04
Abstract: PURPOSE:To evaluate a detecting medium with high accuracy by adjusting the light emitting quantity of a light emitting element by the photodetecting quantity of a photodetector, and deriving the time variation of an electric power applied to the light emitting element of the time when the photodetecting quantity of the photodetector reaches a prescribed value. CONSTITUTION:A detecting part 1 is formed by a dark room, and light from a light emitting element 2 is scattered by smoke, etc. and photodetected by a photodetector 3. The photodetected light is amplified 4 and inputted to a comparing circuit 6. Also, a reference voltage is inputted to a comparing circuit 6 from a comparing voltage (reference signal) generating circuit 5, compared with a signal of photodetecting quantity, and when the signal of photodetecting quantity reaches the reference signal, a signal is outputted to an arithmetic unit 9. Subsequently, a signal from the arithmetic unit 9 is D/A-converted 8 and inputted to a light emitting element driving circuit 7. Also, even if the light emitting quantity of the light emitting element 2 is the same, the photodetecting quantity of the photodetector 3 is varied in accordance with whether smoke exists or not. Accordingly, when an output voltage of the photodetecting side from the comparing circuit 6 reaches the reference voltage, the time variation of an output value to the light emitting element 2 from the unit tor 9 is measured, therefore, the presence of smoke is digitized and can be detected with high accuracy.

Title: Cooling and heating apparatus
Inventor: HAYASHIDA TATSUO
IPC: F24F1/00
Filed: 1979-09-10
Abstract: PURPOSE: To provide a compact cooling and heating apparatus, which is capable of preventing frosting in a combustor during cooling operation and decreasing the size of the cabinet by eliminating an expansion tank for preventing pressure rise.  
     CONSTITUTION: At the time of heating operation, air in the room is drawn from an air inlet port 6 by in an indoor fan 4 and heated by a forced suction and exhaust type combustor 12 that has been kept in operation. Air thus heated is blown out into the room from an air outlet port 5. On the other hand, air supplied to combustor 12 is drawn by a burner fan 15 via a suction and exhaust pipe 13 and an air supply hose 17 and combusted after mixing with fuel injected into the combustor 12. Then, the combustion gas is discharged to the outside from an exguast pipe 14. Here although a cooling heat exchanger 2 is disposed immediately under combustor 12, it is not heated so much by combustor 12 since it is located on the downstream side in the air passage, which results in enabling to omit an expasion tank for preventing pressure rise. Thus, a compact cooling and heating apparatus can be obtained.
