Abstract: Provided is a method for producing cellulose particles or cellulose acetate particles. By a production method including: (a) dissolving cellulose acetate in an organic solvent and preparing a cellulose acetate solution; (b) obtaining an emulsion of the cellulose acetate solution and an aqueous medium using a porous membrane; and (c) precipitating cellulose acetate particles from the emulsion, cellulose acetate particles are produced. By further saponifying the cellulose acetate obtained by the production method, cellulose particles are produced.

Abstract: The purpose of the present invention is to reduce a workload for mapping a physical mounting location of a network interface with the information added to the network interface. A computer system according to the present invention acquires a device address of a network interface recognized by the OS of a computer and identifies the mounting location of the network interface by using a table describing a mapping relationship between the device address of the network interface and the mounting location thereof (see FIG. 1).

Abstract: In a data center, when a server is disconnected from the Internet because of illegal manipulation of a file, valid files (not manipulated) are copied to a standby server and the processing is resumed after a short period of disconnection. According to the invention, a control program P10 performs manipulation checks for all files listed in a manipulation checklist. If any of them is manipulated, it issues a request to disconnect from the external network and a request to assign a standby server to a control program P20 of a management server. Upon receipt of a disconnection completion signal and the address of a standby server b0, the control program P10 copies valid files (not manipulated) to the standby server b0, and for invalid files, requests the copies of their backup files. After finishing copying, the management server connects the standby server b0 to the external network to resume processing.

Abstract: When a load of a user is fluctuated, a data center dynamically changes resource allocation to the user according to the load and holds security for each user. A control program on a data center managing server creates a VLAN configuration table so as to allocate a user-dedicated VLAN including plural network switches for each user company, thereby configuring the ports of a load balancer and network switches allocated to a user to the user-dedicated VLAN. A VPN is configured from the user to the data center, whereby a VLAN tagging technique is used to hold security of the user from the user to the data center. The control program compares a user condition setting table created along the service level agreement for each user with the monitoring result of the computer operating state (the CPU utilization history in a VLAN operation table) to dynamically change the computer allocation and VLAN configuration at unsatisfied agreement.

Abstract: At a data center, operation for security management, such as tampering checks, is automatically implemented for a server allocated to one user of the data center without declining the user task processing performance of the servers in the data center. If control is exerted to deallocate one of the severs out of the user tasks, a server is deallocated such that no new load is assigned to the server to be checked for security management. At user-specified time intervals at which such operation is to be performed for one of the servers allocated to a user, judgment is made regarding whether an idle server is available. If available, the idle server is allocated to the user to resume the work load of the server to be checked for security management. If it is determined that no idle server is available, the load on the server to be checked for security management is reduced so as to perform the check for security management on the server.

Abstract: Disclosed is a touch input pen which is capable of changing its length and diameter when it is used and stored. Its outer diameter can be increased for assuring easy holding when inputting characters and graphics. The touch input pen comprises a pen-body portion having a through hole extending along the axial line thereof and having a tapered front end, a knob portion having a knob with a pen-sliding shaft 8 slidably inserted into the through hole in the pen-body portion, a grip portion composed of a plurality of chuck-like elements slidable on the tapered portion of the pen-body portion and a pen tip. A head portion secured to a front end of the pen-body portion and the pen-sliding portion can be moved to cover a head portion in a head holding portion by manipulating a knob.

Abstract: The present invention provides a power supply backup device for a portable electronic apparatus having a main battery and an auxiliary battery for supplying power when a voltage of the main battery drops. The power supply backup device comprises a backup battery for supplying power at a time of an exchange of at least one of the main battery and the auxiliary battery, a mechanism for detecting a removal of the main battery and the auxiliary battery respectively from the apparatus, and a mechanism for switching over a circuit for connecting the backup battery with the apparatus so as to supply power from the backup battery when the detecting mechanism detects the removal of at least one of the main battery and the auxiliary battery.

Abstract: A semiconductor device has a lead frame. The lead frame has a mount portion and a lead portion. A semiconductor chip is mounted on one major surface of the mount portion of the lead frame. The semiconductor chip is connected by an electrical connecting means to the lead portion of the lead frame.

Abstract: Disclosed is a solar cell-powered calculator or the like which features an integrated unit comprising solar cells and a protective filter which provides easier handling and minimum damage to the solar cells during handling processes. Such a solar cell-powered appliance easily implements electrical connection either between the solar cells themselves or between solar cells and peripheral electronic parts merely by placing the cell-filter integrated unit inside the cabinet in a simple process. In addition, such an advantageous configuration makes it possible to replace the solar cells using an extremely simple process.
