Title: Superconductive element
Inventor: IWASHITA SETSUYA
IPC: H01L39/22
Filed: 1990-01-26
Abstract: PURPOSE:To realize a planar type very fine tunnel junction without deteriorating it in superconductive characteristics by a method wherein the surface of a specific crystal substrate is etched as deep as required into a required form, and a superconductive thin film is formed on the etched recess concerned. CONSTITUTION:A superconductive element of planar type superconductor/ semiconductor/superconductor junction is composed of an insulator region 1 of a crystal substrate, a semiconductor region 2, and a oxide superconductive thin film 3. A part of an SrTiO3 substrate is turned into semiconductor to obtain a superconductive element, and a photoresist 4 is applied onto the substrate. In succession, a patterning mask is formed, and the crystal substrate is etched in accordance with the mask. In succession, a superconductive thin film is made to grow epitaxially as high as the upside of the semiconductor part. A c axis is oriented vertical to the substrate, whereby a tunnel junction can be easily obtained. As a superconductive thin film is not directly etched, it can be prevented from deteriorating in superconductive characteristics. Lastly, the resist and the superconductive thin film on the resist are removed, and thus a thin planar type superconductor/semiconductor/superconductor junction can be obtained.

Title: Manufacture of film sheet and liquid crystal display device using the same
Inventor: SASAKI JUN
IPC: G02F1/1335
Filed: 1994-02-14
Abstract: PURPOSE:To manufacture a birefringent film, which can have field angle characteristics greatly improved, through a simple process at low cost with high mass-productivity by including a process wherein the temperature of a recess-side surface is raised temporarily above a glass transition point and then lowered below the glass transition point. CONSTITUTION:The curled inside of a film made of thermoplastic resin which is <=0.0004 in difference between a smaller refractive index between main refractive indexes in orthogonal directions in a plane of the plastic film and the refractive index in the thickness direction is heated above Tg by a hot blast heater, and the outside is cooled below Tg by blowing a blast of cooling temperature T3. Then a blast of temperature T1 which is lower than Tg at the part of temperature T2 and higher than Tg at its center part is blown to an entrance and an exit where the film is curled. Consequently, the internal surface of the film is heated temporarily to above Tg when passing through the center part. Thus, the film is curved inward and outward repeated to repeatedly cause the compressive deformation of alternate surfaces, thereby varying the refractive index in the thickness direction.
