Abstract: According to one embodiment, a memory system includes a nonvolatile memory and a memory controller. The nonvolatile memory includes blocks each including memory cells. The memory controller is configured to control access to the nonvolatile memory. The memory controller is configured to: set a first block, among the plurality of blocks, to be written in a first mode, the first mode being a mode in which data of a first number of bits is written into the memory cell, and set a plurality of second blocks, among the plurality of blocks, to be written in a second mode, the second mode being a mode in which data of a second number of bits is written into the memory cell, the second number being larger than the first number; acquire access information related to the second blocks; and change a writing mode of the first block which has been set in the first mode to the second mode when a first condition of the second blocks based on the access information is satisfied.

Abstract: An image forming apparatus having a network communication function, includes a data input unit which inputs digital data; a data transmission unit which transmits the input digital data to a data management server for management of data; a digest generation unit which generates a digest of the input digital data; a digest storage unit which stores the digest generated by the digest generation unit; a time stamp acquisition unit which acquires a time stamp for authentication of an input time of the digital data from a time stamp station by issuing a time stamp request including the stored digest at a scheduled time; and a data management directive unit which transmits the acquired time stamp to the data management server for management of the time stamp and the transmitted digital data, associated with each other.

Abstract: A storage medium readable by a computer stores a program of instructions executable by the computer to perform a function for supporting editing of a hierarchical structure of a directory. The function includes: editing metadata including information relevant to the hierarchical structure of the directory; editing content data as contents of a document; analyzing the metadata; and creating a new hierarchical structure of the directory on the basis of a result of the analysis and the content data.

Abstract: A print service support system for supporting print service for producing prints related to data while delivering the data among a plurality of agencies including a unit for accepting information for specifying the plurality of agencies, a unit for generating project information as information for specifying agencies to carry out a project to specify the plurality of agencies and remarkable machine information for specifying a given remarkable print output machine, a selection unit for selecting at least one piece of the information for specifying the agencies, which information is included in the generated project information, a unit for generating device link profile information for the agency including information for simulating color reproducibility of the remarkable print output machine using a print output machine, and information for specifying the agency, and a storage unit for storing the generated device link profile information.

Abstract: Both of a user side and a protect side such as a programmer of an application programmer need not handle a large number of inherent information such as authentication keys. An access ticket generation device generates an access ticket from user unique identifying information and access rights authentication feature information. As unique security characteristic information, there is used a secret key of an elliptic curve encryption or an ElGamal encryption. A proof data generation device receives the access ticket, converts authentication data received from a proof data verification device into proof data by use of the access ticket and the user unique identifying information, and returns the resultant proof data to the proof data verification device. The proof data generation device or the proof data verification device decrypts the above-mentioned encryption.

Abstract: A mechanism for connecting ornamental parts of wrist watches that permit easily connecting and disconnecting ornamental parts without using any special tool and without marring the appearance of wrist watches. A stepped pin is inserted in a larger-diameter bore of a cocoon-shaped ring fitted in an end piece and a bore in a watch casing. Then, a smaller-diameter part of the stepped pin is moved into a smaller-diameter bore by pulling the watch casing and a band longitudinally. With the stepped pin thus securely held in place, the watch casing and band are firmly connected.

Abstract: A work station apparatus includes an electronic mail function. In the work station apparatus, a transmission box icon and object icons indicative of objects to be transmitted are displayed on the display screen of a display unit, and an instruction for transmitting an electronic mail is given in a manner such that a desired object icon is selected from the object icons and is placed on the transmission box icon. The work station apparatus includes a storing unit for storing the destination data set in connection with the transmission box icon, a developing unit for developing the destination data into destination data of the data body corresponding to the object icon in response to the instruction for transmitting the electronic mail, and a transmitting unit for performing a transmission process of the data body according to the developed destination data.
