[Problems to be Solved] To provide a novel ultraviolet light receiving element which is selectively sensitive to ultraviolet radiation, and a method for measuring the dose of ultraviolet radiation using the ultraviolet light receiving element.[Means to Solve the Problems] An ultraviolet detecting layer composed of a thin film of a metal fluoride, such as cerium fluoride, lithium fluoride, magnesium fluoride or calcium fluoride, is formed on a substrate of silica glass, sapphire or the like. Further, at least a pair of an anode and a cathode are formed on the ultraviolet detecting layer to prepare an ultraviolet light receiving element. This ultraviolet light receiving element changes in electric resistivity in accordance with the dose of incident ultraviolet radiation. Thus, the dose of ultraviolet radiation can be measured by taking out and measuring the change as an electric signal.

A moving image distribution system, wherein the user can view content moving images at no charge, and the provider of the content moving images can prevent a drain of the moving image contents and can protect the copy right thereof, as a copy right holder, without fail. The moving images are divided, along a time axis, into two master and slave nonreproducible moving image files. The slave moving image file (small file) is encrypted based on CM file data in which a predetermined CM element has been incorporated. In response to a reproduction request of a user terminal that possesses the master moving image file (main file) in advance, the slave moving image file is distributed with the CM moving images to the user terminal via a network line such as the Internet.
摘要:
An object and project of the present invention is to provide a method for producing silicon fine particles and a method for controlling a particle diameter of silicon fine particles which enable efficient production of silicon fine particles having a uniform particle diameter. A the characteristics of the present invention is producing silicon fine particles having a smaller particle diameter than silicon particles and controlling a particle diameter of silicon fine particles by immersing the silicon particles into an etching solution and irradiating the silicon particles immersed in the etching solution with light having a larger energy than a band gap energy of the silicon particles.

摘要:
When the sensor block 10 is placed on the roller block 20 and the reading surface of the reading sensor 31 faces the aforementioned driving roller 28, then paper is automatically fed with the driving roller 28 and text and image data are read with the reading sensor 31. On the other hand, when the sensor block 10 is reversed 180.degree. and placed again over the roller block 20, then the reading sensor 31 reads text and images when the sensor block 10, arranged beneath the roller block 20, are moving or the document by manual operation.

A method for forming a porous thin film is characterized by formation of a composite thin film on a substrate, in which film a metal portion composed of a first metal component and a metal compound portion composed of a compound of a second metal component which is different from the first metal component are mixed-dispersed, and following lo removal of the metal portion from the composite thin film. A method for forming a porous thin film is alternatively characterized by formation of a composite thin film on a substrate, in which film a first metal portion composed of a first metal component and a second metal portion composed of a second metal component which is different from the first metal component are mixed-dispersed, and following removal of either one of the metal portions from the composite thin film.
