Abstract: PURPOSE:To obtain a superconducting FET which operates at a high temperature with stable characteristics by employing a laminated layer structure of an oxide superconductor and nonmagnetic transition metal compound exhibiting superconductor-semiconductor phase transfer by applying a voltage thereto. CONSTITUTION:A nonmagnetic transition metal oxide 3, an oxide 4 having a channel for causing a superconductor-semiconductor phase transfer are laminated by a sputtering method through an SiO2 film on a p-type Si substrate 1, and electrodes of source 5, drain 6 and gate 7 are attached thereto. The compound 3 is selected form an LaNiO3, LaCoO3, SrFeO3. The compound 3 is selected from LaNiO3, LaCoO3, SrFeO3. The oxide 4 is a perovskite type oxide superconductor having rare earth element having high critical temperature, such as ABa2CU3O7-8 (A is rare earth element, such as Y, Yb, Ho, Dy, Eu, Tm, etc.) having O defect. When the gate electrode 7 is biased to zero or negative, a laminated layer film exhibits superconductive, while when it is biased to positive, hole concentration in the film 4 near a gate is reduced, normal magnetic ions are generated in the film 3 to become normal conductive, and an FET is turned OFF, This apparatus can be operated by a simple refrigerating machine, ageing change is less, and characteristics are stable.

Taking a bath can be also easily carried out with a device such as a showerbath in the standing state. A standing bed 5 is made horizontally turnable, and the sides and back thereof are made easily accessible to a nurse. A meal is taken in the standing state with one's own hands, so that personal dignity can be maintained. Thus, home treatment is enabled for meeting the needs of the times of an advanced age.

Title: Resonator and microscope having resonator
Inventor: KAWAI HITOSHI
IPC: G02B21/00
Filed: 1999-04-26
Abstract: PROBLEM TO BE SOLVED: To provide a small-sized resonator which can be easily assembled and which is stable in operation, and to provide a microscope equipped with the resonator. SOLUTION: The laser light L continuously enters the resonator through a flat plate 61, piezoelectric device 11 and reflection mirror 10, and is reflected by two reflection mirrors 10, 20. The laser light L propagates in a ring of the reflection mirror 10, reflection mirror 20, prism 30 and then again reflection mirror 10, and it resonates with the laser light entering the resonator through the reflection mirror 10 to enhance the power. The laser light L with enhanced power is converted by a wavelength conversion device 40 into second harmonic wave light, which is then continuously emitted from the resonator through the reflection mirror 20, piezoelectric device 21 and flat plate 71.  The errors generated during producing or assembling the reflection mirrors 10, 20 which constitute the resonator can be corrected by only moving the plates 61, 71 along the side faces 50a, 50b of the package 50 tilted only by the Brewster angle.

Filed: 1983-07-01
Abstract: PURPOSE:To perform high quality printing while preventing the generation of a broken character by constituting the titled platen of rubber with elastic hardness of 16-60 deg. so as to bring the surface in its printing front surface side into flat contact with a thermal head by slight pressing in a printing direction. CONSTITUTION:During printing, a thermal head 6 is brought into contact with a platen 20 under pressure vertically in a diameter direction to the center of said platen 20 around its center, that is, the center of thermal elements 7a-7g. The surface of said head 6 at the pressure contact part is elastically deformed to a flat surface shape by this pressure contact force and the thermal head 6 is uniformly contacted with the platen 20 through printing paper 9 without forming a gap therebetween. Therefore, a broken character is not generated during printing. In this case, because the surface 20a of the platen 20 is a curved surface near to a flat surface, the dimension of elastic deformation for obtaining a flat surface is made smaller than a conventional dimension and pressure conact force is also made small. In addition, because a space S is present, the platen 20 is easy to elastically deform.
