Abstract

PURPOSE:To freely impart electrically/electronically functional characteristics to the surfaces of screen face members and obtain the novel screen face members capable of being used for multi-purpose applications and also structures utilizing said members by a method wherein a thin film having electrically/electronically functional characteristics is deposited in a vapor phase in the form of a single layer or of a multi-layer on the surface of the screen face members. CONSTITUTION:Sheets or films comprising various kinds of base materials or structures, such as, for example, a sheet made of such fibers as natural fibers, a synthetic resin film, or a composite of the sheet or the film and inorganic fibers or metallic fibers and, further, a multi-layer sheet or a multi-layer film, can be used as a flexible sheet or a flexible film, which can be used for thin film screen face members as a base material. In accordance with the purpose of using the screen face members or with the application of the same, an electric or an electronic function is imparted to a thin screen to be deposited in a vapor phase onto the surfaces of the screen face members. In order to impart such functional characteristics, the thin screen consisting of metal, alloy, inorganic substances or organic substances, or a mixture of them or a reactant therefrom is deposited in the vapor phase in the form of a single layer or of a multi-layer. The deposition of the layer onto the surfaces of the screen face members is performed by means of vacuum deposition, sputtering, CVD, an ion-plating process or the like. The screen face members 2 on which, for example, electrochromic films 1 are deposited may also be mounted on the wall surfaces in a multi-purpose home so as to be colored or decolored by supplying power to the screen face members.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a thin film screen body and its structure. More specifically, the present invention provides electrical and electrical equipment useful for public facilities, monuments, advertising displays, etc.
This paper relates to a new thin-film screen with excellent electronic functionality and its structure.

(Prior art and its problems) Conventionally, various types of curtains with relatively large areas have been used in public facilities such as sports facilities, concert halls, and other multipurpose halls, monuments, and even public notice displays. It's coming.

Furthermore, in recent years, it has also been attracting attention that air WA structures such as dome structures are formed using these curtain panels.

Of course, on a smaller scale, various curtain panels have also been used as tents, sunshades, etc.

The material compositions of these curtain panels vary, and their surfaces have also been decorated in various ways by means of printing, sewing, etc.

However, there are increasing demands for the design and functionality of these curtains, and in the case of fixed support structures, curtains with the same configuration are being used for sports, concerts, theater, etc. However, there is a need for multipurpose devices that allow changes in design and function, but so far it has not been possible to meet these demands.

With existing technology, electrical and electronic functional surfaces have already been realized by means such as liquid crystals and electrochromics, even if the surface area is relatively large in the case of rigid surfaces. Such functionality cannot be imparted to curtains used for relics that have a large surface area and are flexibly supported under tension.

It can be said that originally there was no idea of adding such functionality.

This invention was made in view of the above circumstances, and it overcomes the drawbacks of the conventional curtain surface, allows electrical and electronic functionality to be freely imparted to its surface, and can also be used for multipurpose purposes. The purpose of this project is to provide a new curtain surface body that can be used for a variety of purposes, as well as structures using the same.

(Means for Solving the Problems) The present invention solves the above problems by adding metal,
A four-layer screen body is provided, characterized in that it is formed by vapor-depositing an electric/electronic functional thin film made of an alloy, an inorganic substance, an organic substance, or a mixture or reactant thereof in a single layer or in multiple layers.

In particular, the present invention provides, as a preferable embodiment, a thin film curtain body formed by vapor phase deposition by ion plating.

Furthermore, the present invention provides a structure in which the above-mentioned thin film curtain body or a connected body thereof is supported by a group or a wire rope,
These air membrane structures are also provided.

The material of the flexible sheet or film as a base material that can be used for the thin film curtain of the present invention is not particularly limited, but for example, sheets made of fibers such as natural fibers, synthetic fibers, glass IIm fibers, synthetic resin film,
Alternatively, composites of these with inorganic fibers or metal fibers, and materials made of various materials and structures such as multilayer sheets and multilayer films can be used.

More specifically, vinyl chloride resin, polyester resin,
Examples include flexible sheets and films made of Teflon resin and composites of these and glass fibers.

The thickness and strength of these base materials depend on the purpose of use of the curtain surface,
It can be determined depending on the purpose.

The Wi film to be vapor-phase deposited on the surface of these curtains can be similarly selected depending on the intended use of the curtain, and its functions include, for example, conductivity, photo-electric conversion, optical display, or dielectric properties. Electrical/electronic functions such as gender can be added.

In order to impart these functionalities, in the present invention, a single layer or a thin film made of metal, alloy, inorganic or organic material, or a mixture or reactant thereof is applied to the surface of the flexible sheet or film. Deposited in vapor phase in multiple layers.

Various kinds of thin film-forming substances can be used at this time, and various compositions of mixtures and reactants can be used.

For example, conductive films, dielectric films, electrochromic films, etc. are exemplified as their functions, and correspondingly, for example, I'rO, Aj203, BaTiO3, WOx, 5
Examples include tyx, TiN, TiO-A, 11203, and mixtures of these with organic polymers such as polyacrylate and polycarbonate.

3.Au/MgF/Cr2o3/WO3/Au,
InO3/CrO3/Ta205/Wo3/I n 0
A multilayer film such as No. 3 may also be used.

Deposition of these materials onto the surface of the curtain surface is carried out by means such as vacuum evaporation, sputtering, CVD, and ion plating. From the viewpoints of adhesion strength, uniformity of the thin film, greater degree of freedom in imparting functionality, etc., it is preferable to employ the high frequency excited ion plating method for the product.

Furthermore, at this time, when depositing metals, alloys, or inorganic substances, it is also effective to vapor-phase deposit 11Th at the same time. A thin WA curtain surface body with high adhesion strength, excellent durability, and no peeling or deterioration can be obtained.

Of course, the desired thin film can also be obtained by combining the ion plating method with other methods.

Organic molecules having both coloring/decolorizing functions may be used to form a thin film, such as tetrazoliums, organic europium compounds, organic samarium compounds, phenolphthalene, nitrosalicylic acid, spiropyrans, and leuphoramines. is exemplified. Also, in response to this,
