  • Patent number: 6987273
    Abstract: In a sterilizer for sterilizing an object to be sterilized utilizing microwaves of a microwave oven for home use, an electrodeless discharge bulb, which seals a material such as mercury which discharges owing to receiving microwaves and emitting ultraviolet rays, is fixed in an inside of a container. An object to be sterilized is held in the container in a manner so that an objective face to be sterilized of the object faces an ultraviolet ray emitting face of the electrodeless discharge bulb. In such a state, the container is put into an inside of the microwave oven, and the microwaves are irradiated, so that the ultraviolet rays emitted from the electrodeless discharge bulb are irradiated to the objective face of the object for processing the serialization.

  • Patent number: 5607899
    Abstract: A thin film strongly orienting specific crystal axes is deposited on a polycrystalline or amorphous base material in accordance with laser deposition in a simpler device through a simpler process. A target is irradiated with a laser beam, for forming a thin film in accordance with laser ablation of depositing a substance scattered from the target on a base material. In order to form the thin film, prepared are conditions capable of forming a film orienting a specific crystal axis substantially perpendicularly to the base material in substantially parallel arrangement of the target and the base material. Under the conditions, a film is deposited on the base material which is inclined at a prescribed angle .theta. with respect to the target. It is possible to deposit a film strongly orienting a specific crystal axis in a plane substantially parallel to the base material surface by inclining the base material under the specific film forming conditions.

  • Patent number: 5372991
    Abstract: An oxide superconductive wire is provided by, for example, forming an oxide superconductive layer on a tape-type flexible base. A preliminary compressive strain is applied to the oxide superconductive layer in the longitudinal direction. The remaining strain can be provided by using a base having thermal expansion coefficient larger than that of the oxide superconductive layer and by cooling the same after heat treatment, due to contraction of the base. Since the preliminary compressive strain is applied to the oxide superconductive layer, degradation of superconductivity of the oxide superconductive layer can be suppressed even if the oxide superconductive wire is bent in any direction, compared with the wire without such strain. Therefore, the oxide superconductive wire can be coiled, for example, without much degrading the superconductivity.

  • Patent number: 5372089
    Abstract: Disclosed herein is a method of forming a single-crystalline thin film having excellent crystallinity on a base material without depending on the material for and crystallinity of the base material. In this method, a base material is provided thereon with a mask which can prevent chemical species contained in a vapor phase from adhering to the base material. The base material is continuously moved along arrow A, to deliver a portion covered with the mask into the vapor phase for crystal growth. Thus, a thin film is successively deposited on the portion of the base material, which is delivered from under the mask, from the vapor phase. A crystal growth end is formed on a boundary region between a portion of the base material which is covered with the mask and that which is exposed to the vapor phase, so that a crystal having the same orientation as the growth end is grown on a portion of the base material newly exposed by the movement.

  • Patent number: 5130296
    Abstract: When an oxide superconducting thin film is formed on a substrate by a vapor phase method such as laser ablation, for example, a plurality of grooves are formed on the substrate by photolithography or beam application in the same direction with an average groove-to-groove pitch of not more than 10 .mu.m, so that the oxide superconducting thin film is formed on a surface provided with such a plurality of grooves. Thus promoted is growth of crystals of the oxide superconducting thin film in parallel with the grooves, whereby respective directions of a-axes and c-axes are regulated to some extent. This improves critical current density of the oxide superconducting thin film.
