Abstract: PURPOSE:To manufacture a superconducting junction of stable performance with good reproducibility by constituting the junction from the thin film of an oxide superconductor, which is formed on a substrate having a square pillar-shaped protrusion with the bottom face perpendicular to a film-forming surface and one side face almost perpendicular to the film-forming surface in the manner of crossing the protrusion and of which the part on the side face of the protrusion almost perpendicular to the film-forming surface is thin. CONSTITUTION:In the title superconducting junction, e.g. a substrate surface is first etched by Ar ion milling so that a square pillar-shaped protrusion is formed on a substrate 4. Then, the substrate 4 with the protrusron 40 formed thereon is heated to 590-650 deg.C so that there is formed the thin film 1 of an oxide superconductor in the shape of crossing the protrusion 40 of the substrate 4. When the oxide superconductive thin film 1 is formed at the substrate temperature, there is formed an oxide superconductive thin film 1 composed of c-axis oriented oxide superconductor crystal. The cross section of the protrusion 40 is rectangular and its side face 41 is perpendicular to the film-forming surface of the substrate 4. Also, the protrusion 40 is 150nm in height and 10mum in maximum width. The oxide superconductive thin film 1 is divided into superconductive layers 11 and 12 of about 300nm thickness and a weakly combined part 13 on the side face 41 of the protrusion 40. The thickness of the weakly combined part 13 is about 10nm.

Abstract: PURPOSE:To easily form a fine pattern whose order is less than or equal to submicron, by bringing first gas containing oxygen into contact with a substrate, irradiating a desired pattern with an electron beam to form an oxide film, using said film as a mask, and performing etching with etching gas. CONSTITUTION:In an etching chamber, oxygen gas 12 is introduced from a mask forming gas feeding inlet to a substrate on which a GaAs layer 11 is epitaxially grown. The substrate surface is irradiated and scanned with an electron beam 13. After the gas 13 is discharged, mixed gas 15 of chlorine and hydrogen is introduced from an etching gas feeding inlet, and a grating whose period is 0.3mum is formed by etching. While the surface of the substrate 10 is irradiated with an arsenic molecular beam, the substrate 10 is heated at 500 deg.C or higher for about 2 hours. By the effect of surface cleaning, a surface oxide film 14 and chlorine compound attached on the GaAs substrate 10 surface during etching are eliminated. Thereby a grating pattern whose period is 0.3mum can be formed on the GaAs surface, without taking out the substrate from an ultra-high vacuum system.

Abstract: PURPOSE:To prevent the cool air feeling of inhabitants, by a method wherein the lowest operating frequency of a compressor is set by a lowest operating frequency setting means based on the set flow rate of air and an atmosphere temperature so that the frequency is set higher when the set flow rate of air is larger and the same frequency is set higher when the atmosphere temperature is lower. CONSTITUTION:The operating frequency of a compressor 8 is controlled fundamentally based on a difference between a room temperature and a set temperature. The lowest operating frequency under this control is set based on the set flow rate of air, which is set by a flow rate of air setting means 3, and an atmosphere temperature, detected by an atmosphere temperature sensor 2, so that it becomes higher when the set flow rate of air is larger and it becomes higher when the atmosphere temperature is lower. The lowest operating frequency of the compressor 8 is increased when the set flow rate of air is large whereby inhabitants will never feel cold air feeling even when a heating capacity is increased and the flow rate of air is high. When the atmosphere temperature is low and the amount of heat, absorbed by an outdoor heat exchanger from atmosphere, is small, the lowest operating frequency of the compressor is increased whereby the inhabitants will never be provided with the cold air feeling even when the heating capacity is increased but the atmosphere temperature is low.

IPC: F24H1/18
Filed: 1985-12-06
Abstract: PURPOSE:To prevent hot water in a water tank from being used up in case power failure happens to occur in the time zone when midnight power is supplied, by heating water at the maximum rate by effectively using the remaining time as soon as the power failure is recovered. CONSTITUTION:The water temperature in the lower part of a hot water tank 1 is detected by a temperature sensor 3. A water temperature and heated-water temperature determining means 4 determined the temperature in a feed water and the water temperature to be heated up from the detected value by the sensor 3. A processor 6 calculates the net heating time, the starting time of heating and the temperature to be heated up for an electric heater 2, based on the output from a demanded quantity of hot water setting means 5 and that from the water and heated-water temperature determining means 4. Besides a time switch 8 controls the supply of power from a power source 7 to the heater 2, and a signal detecting means 10 detects whether power is supplied by the power source 7 or not. When a power failure detecting means 11 detects a power failure from the output of a signal detecting means 10, a heater controlling means 12 controls the heater 2, based on the result calculated by the processor 6 and the output from the power failure detecting means 11. As a result, hot water being used up in the water tank 1 can be prevented.

The phase synchronizing oscillator 30 has the phase synchronized with the input clock and freely runs with the input clock phase just before the break of the clock input 10 even during this break. A counter B40 counts the clock from the phase synchronizing oscillator 30 and outputs the counted value to the coincidence circuit 50. This circuit 50 takes counted values from the counter A20 and the counter B40 as the input and compares them with each other and outputs an equality signal in the case of equality between both count values and outputs an inequality signal in the case of inequality. When the signal is outputted, it is detected as a clock break detection output 60 to detect the clock abnormality.
