In order to enable a medical worker to certainly and easily know whether a patient on a home oxygen therapy, who continues to inhale an oxygen-enriched gas at home, performs the inhalation as prescribed, a history of a supply condition of the oxygen-enriched gas supplied to the patient is recorded and held as supply history information, this supply history information is compared with a prescription of the oxygen therapy of the patient to generate patient's compliance information to indicate the degree to which the oxygen therapy is performed in accordance with the prescription, the oxygen concentrating apparatus is constructed to be portable, and a doctor can confirm the patient's compliance information at the time of going to a medical institution regularly.

A superconductive device and method for the manufacture thereof is disclosed, having a tunneling Josephson element comprising a first oxide superconductor electrode, a blocking layer consisting of a metal substantially inert to oxygen formed on the surface of the oxide superconductor, an insulating thin film layer formed on the blocking layer, and a second superconductor electrode opposing said first electrode formed on the insulating thin film.

A superconducting logic circuit has a first and a second one-junction SQUID's (superconducting quantum interference device) connected by a superconducting inductor, the junction of the second SQUID having a larger critical current than that of the first SQUID, the inductance of the second SQUID being smaller than that of the inductor, and a signal applied to the first SQUID is unidirectionally transmitted to the second SQUID by applying bias currents to the junctions of the two SQUID's.

Unidirectional single-flux-quantum logic circuit

An ion selective field-effect sensor selectively sensitive to a particular cation to be measured is disclosed. In the sensor is used a giant heterocyclic compound selectively forming a complex with the particular cation as an ion sensitive film provided on a surface of a field-effect semiconductor device.
