    Abstract: After an underlying layer, made of a single crystal metal material, has been formed on a semiconductor layer, part or all of the underlying layer is changed into a metal oxide layer by supplying oxygen thereto from above the underlying layer. Then, a ferroelectric or high-dielectric-constant film is further formed on the metal oxide layer. Since the film made of a metal material is formed on the semiconductor layer, a silicon dioxide film or the like is not formed easily. Thus, a dielectric film, which includes an underlying layer with a high dielectric constant and has a large capacitance per unit area, can be obtained. Various defects such as interface states in the semiconductor layer can also be reduced advantageously if these process steps are performed after a thermal oxide film has been formed on the semiconductor layer.

    Abstract: The present invention provides a magnetic head having improved characteristics, using a magnetoresistive device in which current flows across the film plane such as a TMR device. In a first magnetic head of the present invention, when the area of a non-magnetic layer is defined as a device cross-section area, and the area of a yoke is defined as a yoke area, viewed along the direction perpendicular to the surface of the substrate over which the yoke and the magnetoresistive device are formed, then the device cross-section area is not less than 30% of the yoke area, so that a resistance increase of the device cross-section area is suppressed. In a second magnetic head of the present invention, a magnetoresistive device is formed on a substrate, and a yoke is provided above a non-magnetic layer constituting the device. In a third magnetic head of the present invention, the free layer of the magnetoresistive device includes at least two magnetic films and at least one non-magnetic film that are laminated alternately, and the thickness of the non-magnetic layer is not less than 2 nm and not more than 10 nm, and magnetostatic coupling is dominant. In a fourth magnetic head of the present invention, a magnetic gap is provided adjacent to the magnetoresistive device and the magnetic films are coupled antiferromagnetically.

    Abstract: An expansion device capable of preventing an abnormal increase in the high-pressure in a freezing cycle and having, as an integrated unit thereof, a mechanism capable of quickly responding to an abnormal increase in the high-pressure and the low-pressure is provided. A means for displacement (bellows) 28 which becomes displaced in correspondence to the high-pressure is linked to a valve element 24 of a restrictor valve mechanism 32 to displace a rod 34 provided with a safety valve mechanism 33. If the high-pressure reaches a level equal to or higher than a first specific pressure (the limit to the normal operating pressure), a first portion 26 of the safety valve mechanism 33 becomes disengaged from a relief hole 27 that communicates between a high-pressure space 29 and a low-pressure passage 31 to be replaced by a second portion 25 which allows passage through the relief hole 27, thereby leaking the coolant in the high-pressure space 29 to the low-pressure passage 31 and preventing a further increase in the high-pressure. In addition, a low-pressure side rupture disk mechanism 40 that becomes ruptured if the low-pressure reaches a level equal to a second specific pressure to communicate between the low-pressure passage 31 and the atmosphere is provided at the low-pressure passage 31. A high-pressure side rupture disk mechanism 50 that becomes ruptured if the high-pressure reaches a level equal to or higher than a third specific pressure to communicate between the high-pressure passage 30 and the atmosphere is provided at the high-pressure passage 30.

    Abstract: For applying ferroelectrics to electronic devices, the poling treatment of the ferroelectrics has been necessary in order to uniform directions of spontaneous polarizations, Ps, in each ferroelectric. This treatment brings about (1) low yields of the devices, (2) difficulties in the fabrication of array devices, and (3) difficulties in the formation of ferroelectric films on semiconductor devices. Now it has been found that a self-polarized film in which spontaneous polarizations, Ps, are unidirectional can be formed by sputtering a ferroelectric materials containing lead under such conditions that the orientation of Ps will be controlled without poling treatment and a high-performance ferroelectric device can be obtained in a high yield by using this film, and thus a process for producing such devices has been found.
