Abstract: PURPOSE:To prevent a leakage current from flowing between wires so as to prevent the malfunction of a circuit in a superconducting device formed by forming a thin film of a superconducting oxide, insulator, metal, etc., on an SrTiO3 substrate by increasing the resistance of a surface conductive layer formed on the surface of the SrTiO3 substrate at the time of etching the thin film deposited on the substrate. CONSTITUTION:A thin film 12 of a superconducting oxide, insulator, metal, etc., is deposite on an SrTiO3 substrate 11. After applying a resist 13 to the entire surface of the thin film 12, the resist 13 is patterned to a prescribed form. The thin film 12 deposited on the substrate 11 is dry-etched by using the patterned resist 13a and 13b as a mask. Then the resistance of a surface conductive layer 14c formed on the surface of the substrate 11 by dry etching is increased by oxidizing the layer 14c.

IPC: F01M11/12
Filed: 1992-12-25
Abstract: PURPOSE:To provide a liquid level detection device to detect a level of liquid rising in temperature by a temperature sensitive resistor in a short time. CONSTITUTION:A thermal conductive pipe 18 is arranged in oil in an oil pan 14 of a vehicle with its one end inserted into the oil. In the thermal conductive pipe, a PTC thermistor (thermistor) 20 resistance value of which rises with the environmental temperature rises is arranged, and it is devised so that the thermistor 20 appears in the air from oil when the amount of oil decreases. When oil temperature starts to rise in the state where the amount of oil in the oil pan 14 is short, as temperature of the thermal conduction pipe 18 also rises, temperature of the air in the thermal conduction pipe 18 becomes almost the same as the oil temperature even if the temperature of the air in the oil pan 14 is low, and the resistance value of the thermistor 20 becomes larger without being behind rise of the oil temperature.
