摘要:
There is disclosed an invention for generating contract information for an image forming apparatus for which the user is going to conclude a contract. The history information of an image forming apparatus used by the user and having a contract history is stored and managed in correlation with the user. Such management is executed in a center server capable communication with the image forming apparatus through a predetermined communication channel. The above-mentioned information includes contract term, machine type, number of print outputs etc. of the image forming apparatus. Also the image forming apparatus to be managed includes that currently contracted and that contracted in the past. In case the user wishes to conclude a new contract for an image forming apparatus, new contract information is generated according to the history information managed by the center server in correlation with the user. This invention provides a system capable of realizing the foregoing.
摘要:
In a method for transferring information in a form of electron beam, an electron beam detector detects the electron beam, and emission of the electron beam from a predetermined electron beam source is controlled in accordance with a signal from the detector upon detection of the electron beam. A deflection electrode is also used to deflect the electron beams according to an electric or magnetic field to perform charge shifting, logical additions, logical multiplications, image formation, and the like.

An optical modulation device includes: a ferroelectric liquid crystal disposed between a pair of substrates; provision for applying an alternating voltage sufficient to render the ferroelectric liquid crystal turbid; and provision for superposing a DC voltage on the alternating voltage. A portion of the ferroelectric liquid crystal rendered turbid through the application of an alternating voltage is selectively caused to have an increased transmittance when superposed with a DC voltage.

摘要:
An image-recording apparatus which comprises:(a) an image-recording medium comprising a pair of substrates and a thermo-optical liquid crystal provided between the pair of the substrates,(b) a heating means for uniformly heating the liquid crystal up to obtain an isotropic phase,(c) a means for applying an electrical field to the liquid crystal, and(d) a writing means for conducting writing by locally heating the image-recording medium.
摘要:
A communication apparatus receives the identification information of a partner station, and performs a communication operation in accordance with the received identification information. A first detecting unit detects a calling signal. An identification information receiving unit detects the identification information of a calling party upon detection of the calling signal, and a second detecting unit detects whether or not the terminal of the calling party is a data communication terminal. A registration unit registers the identification information of the partner station in a memory, so that whether the partner station is a speech or data communication terminal can be discriminated later. A control unit checks if the identification information receiving unit receives the identification information of the calling party. When the identification information of the calling party is received, the control unit checks if the-received identification information is registered in the memory, and selectively executes a speech communication process and a data communication process in accordance with the checking result and the detection result of the second detecting unit.
