Abstract:
The invention relates to a 1.4-1.52 &mgr;m-band optical amplifier. This optical amplifier includes (a) a first pumping source for a first pumping light in a wavelength range defined as being not less than 0.65 &mgr;m and being less than 0.77 &mgr;m; (b) a second pumping source for a second pumping light in a wavelength range of from 1.0 to 1.2 &mgr;m; (c) an optical multiplexer for combining said first and second pumping lights with a signal light, to produce a combined light; and (d) a light amplifying optical waveguide for amplifying said signal light by receiving said combined light, said optical waveguide comprising a core doped with Tm. The optical amplifier is highly efficient.
Abstract:
In order to make a display of a mail text easy to observe, the size of characters assigned in the mail text is checked, and if the size is not within a predetermined allowable range, the text is displayed on a display device using a font such that the size of characters is within the allowable range. A similar processing is also performed when reproducing voice information added to a mail text.
Abstract:
An image processing apparatus such as a facsimile comprises: a recognizing circuit to recognize special pattern information such as a mark in reception image data; a converter to convert the result of the recognition by the recognizing circuit into the index information corresponding to image information in the reception image data; and a memory to store the index information converted by the converter and the image information so as to correspond to one another. When the user at a remote location wants to obtain image data, the image data can be transmitted from the electronic file system without needing any operator of the file system.
Abstract:
The fluoride glass of the present invention, which contains, as anions, a small amount of chlorine in addition to fluorine, has advantages such as (1) it is less liable to crystallize as compared with a fluoride glass containing no chlorine and yet shows substantially no deterioration in chemical durability and mechanical strength due to chlorine inclusion and (2) its refractive index can easily be changed by changing the addition amount of chlorine.
Abstract:
The present invention provides a nanowire production method that is simpler than conventional nanowire production methods, and that makes it easier to control the size and shape of the nanowires by using a technique completely different from the conventional ones. A powder particle containing a metal element is divided into nanometer-size wires containing the metal element by irradiating a suspension of the powder particles with a femtosecond laser. The present invention also makes it possible to divide the nanometer-size wires thus formed into nanometer-size particles containing the metal element by irradiating further the nanometer-size wires with the femtosecond laser.
Abstract:
In a system for transmitting print data from a server apparatus for forming the print data to a client apparatus and performing print based on the print data, it is an object of the invention to improve security of printed matter by inhibiting reprint using the print data stored in the client apparatus and improve operability upon reprinting.
Abstract:
A network print system which aims at printing high-quality image data of a form is generated using a Web browser. In response to a request from a client to print or to display a document, a server merges an appropriate template with the variable data to produce print data or display data, as the case may be; however, based on whether certain authorization or restriction conditions are applicable to the request being processed, the server in an appropriate case inhibits generation of print data or display data, so that the print request or display request is not fulfilled.
Abstract:
It is desirable for a user to perform optimum printing business in an environment of a print system used by the user, without being conscious of a function of forming document printing data by a server and a function of forming the document printing data by a client. If software for the function of forming the document printing data by the client is installed in a terminal of the client operated by the user, document-form data and document data are distributed from the server to the client in order to use the function.
Abstract:
The invention relates to a three-dimensional optical memory medium capable of recording and reading a large quantity of information therein and therefrom, and a process for producing the same. A recording pulsed laser beam is applied to an arbitrary position in a luminescent-ion-containing solid medium as the solid medium is three-dimensionally moved relative to a converging point of the pulsed laser beam.
Abstract:
An information processing system includes an information management apparatus that accepts image generation requests and an image generation section that generates image data, which is provided independently of the information management apparatus. The information management apparatus issues a job ID in response to a print request from a client, and transmits the job ID and a URL of the image generation apparatus to the client. Based on the URL, the client directly requests the image generation apparatus for image data corresponding to the job ID.
