Abstract: The ink jet recording method performs ink jet recording of an image on a recording medium using an ink jet head. The method allows an electrostatic force to act on ink prepared by dispersing charged particles containing colorants in a dispersion medium to form a thread of said ink, divides the thread into ink droplets of the ink to eject the ink droplets toward the recording medium and allows the ink droplets to be landed onto the recording medium moving relatively to the ink jet head to form an image dot on the recording medium. When a speed at which the recording medium and an ejection portion of the ink jet head for ejecting the ink droplets move relatively is referred to as “v”, a division frequency of the thread is referred to as “f”, and a diameter of the thread is referred to as “d”, the following expression is satisfied: (v/f)<(a×d) where “a” is a coefficient.

Abstract: The ink jet recording method allows an electrostatic force to act on an ink composition containing at least charged particles containing a colorant and a dispersion medium to form a thread of the ink composition, and divides the thread into small portions to eject ink droplets on a recording medium. A first average concentration of the charged particles contained in the thread from its tip end portion to its central portion is higher than a second average concentration of the charged particles contained in a whole thread. And/or, a first force acting on the charged particles contained in the thread is made larger than a second force obtained by subtracting the first force acting on the charged particles contained in the thread from a second force acting on a whole thread.

Abstract: An authentication system stops performing an authentication process on a communication terminal which is in an aborted state. The communication terminal can connect to a network when the authentication thereof is successful. The communication terminal changes between an operational state and an aborted state, and indicates a transition to the aborted state when the communication terminal changes from the operational state to the aborted state. An authentication device repeatedly performs the authentication process, counts a predetermined period for the communication terminal whose authentication has been successful, and performs the authentication process again on the communication terminal when the predetermined period elapses. When a transition to the aborted state is indicated by the communication terminal, the authentication device stops counting the predetermined period for the communication terminal and keeps the authentication of the communication terminal effective.

Abstract: A supply such as an ink tank or the like, which is mounted on an image recording apparatus, includes a recording section in which encoded information created by encoding identification information by a secret key is recorded, and the encoded information is decoded by a decoding key provided with the image recording apparatus and then checked. With this arrangement, it can be advantageously prevented that the supply such as the ink tank or the like is mounted on the image recording apparatus by mistake, whereby the deterioration of image quality, the trouble of the image recording apparatus and the like caused by the supply mounted by mistake can be prevented.

Abstract: Objects of the present invention are to facilitate filling out by hand an electronic paper and to realize digitization of contents with which the electronic paper is filled out by hand with a simple structure. A read image is obtained by optically reading a reading-object of the electronic paper. Based on the document information written on the electronic paper and writing-conditions during document writing, which are represented by the document information, a display image of the document in accordance with the read image information is formed. A written image is separated and extracted by converting a density only of pixels among the respective pixels of the read image, whose densities vary in accordance with the document writing and which correspond to a portion, to which ink of a pen for the handwriting is not adhered.

Abstract: At a host device, attribute information (the presence or absence of an overwriting prohibition and the like) of each of image display mediums (electronic papers) is stored in association with individual identification numbers, which are unique to each image display medium. Hence, when a predetermined image is to be displayed at an image display medium in accordance with input from an operation portion, for example, an image display medium for which an overwriting prohibition has not been written to the attribute information can be selected, and image data can be transmitted to this display medium for displaying the image. Thus, image display at each image display medium can be excellently controlled in accordance with attribute information such as overwriting prohibitions and the like.

Abstract: A recording medium is structured by a recording layer, which is for storing storage data, and an indication layer, which is for indication information used for identifying the storage data, being laminated together. Writing and deletion are possible at the indication layer. A PC generates inputted storage data and indication information for identifying the storage data, and transmits them to a writing/reading device. The writing/reading device writes the storage data and the indication information to the recording medium. The storage data is written at the recording layer, and the indication information is written at the indication layer. The storage data stored at the recording medium can be easily and correctly grasped.
