Title: Deforosting control method for refrigerator
Inventor: OZU TADAO
IPC: F25B47/02
Filed: 1989-06-19
Abstract: PURPOSE:To decide the output propriety of the next defrosting signal by calculating the time length of latent heat change of a vaporizer during defrosting time and the rate of cooling operation during cooling time. CONSTITUTION:During the defrosting of a vaporizer 4 adhered with frost, the temperature of the vaporizer indicates the change in latent heat of 0 deg.C. If the frost is eliminated, the temperature will rise abruptly and exceed 0 deg.C. Therefore, the temperature change at the end point of the change in latent heat is detected with vaporization temperature sensors 11 to 14 so that the time length TB' of latent heat change during defrosting time. Since this time length TB' indicates the amount of frost produced in the previous cooling cycle, it may serve as data to decide whether it is proper or not to practice the next defrosting. However, the cooling condition in the current cycle may be related with the prediction of frosting amount. More specifically, an attempt is made to calculated the cooling operation rate epsilon by taking the ratio between the total opening time TH of a motor-driven valve 3 in the cooling time and the cooling time TA. This cooling operation rate corrects the time length of latent heat change and enables the prediction of frosting amount based on the cooling conditions in the current cooling cycle and judges the propriety of defrosting practice during the next defrosting time.

Title: Apparatus for deciding anomaly in oxygen concentration sensor
Inventor: KONNO YUICHI
IPC: G01N27/409
Filed: 1998-06-03
Abstract: PROBLEM TO BE SOLVED: To decide whether or not an oxygen concentration sensor is abnormal during driving by confirming that an output signal of the oxygen concentration output sensor does not show rich and lean reversals for air-fuel ratio in an air-fuel ratio feedback control drive state. SOLUTION: A CPU 6 determines a fuel injection time with the use of a drive parameter and the number of revolution of an engine. Fuel is injected into an engine 2 during only the fuel injection time. Oxygen concentration is detected by an oxygen concentration sensor 16 from a combustion exhaust gas. By repeating the process, an air-fuel ratio of a supplied mixed gas is fed back to control a theoretical air-fuel ratio. In a fail-safe process, the CPU 6 first decide whether or not a drive state of the engine 2 is in an air-fuel ratio feedback control area and then decides whether or not the drive state is in a rich drive area.  When an output level of the oxygen concentration sensor 16 indicates a lean air-fuel ratio, it is decided whether or not a counted value of an anomaly decision counter is larger than a predetermined value, thereby deciding the oxygen concentration sensor 16 as abnormal.
