摘要:
In an information recording device (10), a content control unit (14a) divides an input content into a plurality of sections and further subdivides each section into recording units with predetermined data amounts. An attached information generating unit (14b) generates attached information necessary for making use of the input information and license. An encrypting unit (15) generates encrypting information by using a number that is included in the attached information and that is allocated to the input information, and encrypts information included in the recording unit by the encrypted information. Further, the information encrypted by the encrypting unit, the attached information corresponding to the input information and the license are associated with every section divided by the content control unit through an outside input and output I/F(11) and the associated information and the license are recorded on a recording medium. Thus, with the encrypting information simply changed for every short section, encrypting and recording are carried out.

There is provided an accounting system for accounting a content distributed by an accumulation broadcast or a removable recording medium while preventing an unauthorized use and holding privacy of a user. An accounting ID specifying the money information stored in a prepaid card is read and a content ID of the encrypted content specified by the user and the accounting ID are reported to an accounting server. Decoding information is acquired in return for the accounting and the encrypted content is decoded by using the decoding information so as to be used.

A recording and reproducing apparatus for recording and reproducing the stream of a content, in which video image and audio streams are extracted from streams of a predetermined format, and a new stream, the edit of which can be freely carried out, is created from the streams and recorded. A recording and reproducing apparatus comprises an input/output interface for inputting a stream, a stream conversion processing portion for converting an input stream of a predetermined format into a stream comprising only a video image stream and an audio stream and a recording medium writing control portion for writing and recording the converted stream in a recording medium. The recording medium writing control portion writes managing information representing that the stream converted by the stream conversion processing portion is recorded in a predetermined area (manufacturer definition area) of the recording medium. The recording and reproducing apparatus can control various functions (display function, edit function, reproduction function, output function, dubbing function, and so forth) according to the managing information.

An electronic device includes an input screen including: a dial keyboard on which multiple characters are annularly arranged for selection by an operator; an input area into which a character selected from the multiple characters is input at an input position; and a movement key for allowing the operator to move the input position at which the selected character is to be input in the input area to determine the input position. The dial keyboard sequentially displays the multiple characters for selection by the operator on the dial keyboard, according to an operation on the dial keyboard by the operator. The input area displays the selected character at the input position determined in response to an operation on the movement key, in response to a selection of a character from the multiple characters by the operator
摘要:
A porous Si layer is formed on a single-crystal Si substrate, and then a p+-type Si layer, p-type Si layer and n+-type Si layer which all make up a solar cell layer. After a protective film is made on the n+-type Si layer, the rear surface of the single-crystal Si substrate is bonded to a tool, and another tool is bonded to the front surface of the protective film. Then, the tools are pulled in opposite directions to mechanically rupture the porous Si layer and to separate the solar cell layer from the single-crystal substrate. The solar cell layer is subsequently sandwiched between two plastic substrates to make a flexible thin-film solar cell.

A photographing apparatus comprises an operation unit, a controller, and a display unit. The operation unit has a range setting unit that is used for setting an upper limited value of a range of a sensitivity of an imaging sensor and a lower limited value of the range in a first sensitivity setting state where the sensitivity is calculated on the basis of a luminance value obtained in a photometric operation. The controller sets the upper limited value and the lower limited value corresponding to an operation of the range setting unit. The display unit displays an illustration of the upper limited value and the lower limited value that are set by the controller.

Provided are an image forming apparatus and a method of controlling the same, an information processing apparatus and an information processing method, and a program for implementing these methods, in which the fact that a setting is to be changed can be reported to a host apparatus through a simple arrangement. The image forming apparatus for attaining this object includes storage unit for storing the latest set value of the apparatus, transmitting unit for transmitting the latest set value, which has been stored in the storage unit, to the host apparatus in response to a request from the host apparatus, and updating unit for receiving a print setting from the host apparatus and updating the latest set value stored in the storage unit.

A transmission screen having a writable and erasable surface for one side is provided. This transmission screen is constructed so that the writable and erasable surface should have a specular gloss (JIS K5600-4-7:1999) of 70 to 135%, the transmission screen as a whole should have a haze (JIS K7136:2000) of 80% or more, and the surface opposite to the writable and erasable surface should have a specular gloss (JIS K5600-4-7:1999) of 10% or less. With this transmission screen, writing with a marker for white boards and erasing can be easily done while seeing images projected on the transmission screen, and the images from a projector do not become hard to see due to projection of the images on the body of a writer.
摘要:
A plurality of solar batteries are provided between a first substrate and a second substrate. The first substrate and the second substrate are formed of, for example, a paper or a non-woven cloth, which is a material including a natural fiber, cellulose, as the main component. Papers and silicon have relatively small difference in coefficient of thermal expansion so that warp caused by changes in the temperature is suppressed. Also, papers are light, easy to be processed and spontaneously decomposed so that disposing becomes easy. The first substrate is preferable to be transparent or semitransparent and preferable to be formed of cellophane paper, glassine paper, parchment paper, or Japanese paper. Oil may be included in the material. The second substrate is preferable to be opaque. A waterproof film may be formed on the first substrate and the second substrate.
