    Abstract: A charged particle beam adjustment assistance device that can assist work to adjust a charged particle beam apparatus having a three-dimensional observing function and reduce human labor and man-hours required for adjustment value inputting is provided. An adjustment value acquiring unit generates optimal three-dimensional adjustment value information on the basis of two-dimensional adjustment value information and two/three-dimensional adjustment value correspondence information generated according to information inputted from a charged particle beam adjuster terminal, transmits the three-dimensional adjustment value information to the charged particle beam apparatus, and sets the three-dimensional adjustment value information therein. Therefore, the charged particle beam adjuster can reduce adjusting work required for three-dimensional observation and facilitate the work of observing three-dimensional images.

  • Patent number: 7631215
    Abstract: A personal digital assistant comprises a loss detector to detect a lost state and a value information retainer for retaining a value assessment index, which are numerical values indicating data values. When a lost state is detected by the loss detector, a data recovery sequence is determined based on the data values and data is transmitted to another terminal. In determining the recovery sequence, electrical energy required for data transmission is calculated using a power consumption table and the remaining battery power level measured by a remaining battery power level meter is referenced.

  • Patent number: 7375615
    Abstract: An apparatus is disclosed for reducing the vexatious complication of personal authentication when using an information technology device or a card. A combination of RFID tags worn by a user is stored when personal authentication is carried out. The RFID tags are detected again In a situation where personal authentication is required. The continuous use of the previous personal authentication is permitted depending on the extent of coincidence between pieces of RFID information thus detected and the combination of stored RFID information, so that further authentication operations can be omitted. In addition, reference is made to a past archive when an RFID list is created. A weighted coefficient is then calculated based on the put-on frequency (put-on archive) in terms of a user's single article or a combination of such articles. The utilization of the weighted coefficient provides personal authentication with a high level of reliability.

  • Publication number: 20060117308
    Abstract: A data processing apparatus (1) can implement the execution of a virtual machine instruction based on an execution routine specified by the native instruction of a CPU (2) and has an address converting unit (3) capable of sequentially converting an address output from the CPU into the address of the native instruction by utilizing the address of a prepared execution routine in response to the application of a prescribed condition. The address converting unit reads a virtual machine instruction to be executed next and prepares the address of an execution routine corresponding thereto in parallel with the execution of the execution routine by the CPU based on the address of the native instruction which is sequentially converted. Accordingly, it is possible to reduce the overhead of a processing of loading the virtual machine instruction and a processing of executing an instruction in accordance with the execution routine which is caused by an address calculation processing based on the load processing.

    Abstract: A film applying apparatus is provided with preparatory bonding rolls, laminating rolls, a laminated film wound out from a film roll and a substrate conveyed by a substrate conveying device. The laminated film passes between these rolls and pressure bonding is performed. The diameter of the preparatory bonding rolls is made smaller than the diameter of the laminating rolls. The range of the elastically deformed area at the roll surface where the grasping of the substrate and the laminated film by the preparatory bonding rolls is begun, is made small, thereby limiting the range and reducing the generated amount of air holding or the like.
