Title: Protective device of light detector
Inventor: YAMASHITA YUTAKA
IPC: G01J1/22
Filed: 1988-12-05
Abstract: PURPOSE:To protect a light detector during a period when strong light of certain definite quantity or more is incident on the side of the detector and to allow light to be incident at the point of time when said strong light becomes less than the definite quantity by providing a photodetector, a control circuit and a light deflecting element. CONSTITUTION:When an object 3 to be detected enters between optical fibers 2, 4, transmitted light toward a light detector 5 suddenly becomes weak to be sent to a photodetector 11 through a beam splitter 10. When the quantity of the light received by the element 11 becomes a definite value or less, the control signal of a control circuit 2 is not outputted. Whereupon, a light deflecting element 9 performs diffraction action on the basis of the signal subjected to defraction control of a drive circuit 13 and diffracts the greater part of the light from a light source 1 to allow said light to be incident to one optical fiber 2. The light is transmitted through the object 3 to be detected through said one optical fiber 2 to be received by other optical fiber 4 and further sent to the detector 5. The bleeder 14 of the detector 5 is released from inverse bias when the control signal from the circuit 12 is lost and the detector 5 returns to usual sensitivity and the data of the object 3 to be detected is obtained by the detector 5.

Abstract: PURPOSE:To protect foodstuff from decaying because of an operation failure of a defrosting temperature detection means by giving an alarm if the time of a defrosting temperature detection means is shorter than its preset time when the defrosting temperature detection means is subjected to higher temperature after power is supplied to a defrosting heater. CONSTITUTION:When an operation timer counts a specified time, a compressor 9 is turned OFF while a defrosting heater is turned ON where a defrosting timer 19 proceeds with counting. Then, the temperature of a defrosting temperature detection means 11 is checked for. If the detected temperature is judged to be too high, the count value of the defrosting timer 19 is read. On the other hand, it is judged to be longer than a preset time, defrosting heater 10 is turned OFF so that cooling operation may be stated. When the time is shorter, it is output to a step alarm means 17 so as to allow the timer 19 to proceed with its count. When it reaches the preset time, the defrost heater 10 is turned OFF so that cooling operation may start. Therefore, when the power supply time to the defrosting heater 10 is extremely short, it can be judged to be an operation failure of the defrosting temperature detection means 11, which forcedly supplies power to the defrosting heater 10 for a specified time.
