Abstract: It is an object of the present invention to provide a combustion power tool having a rational construction. A representative combustion power tool according to the invention may include a combustion chamber, a fuel supplier to supply fuel into the combustion chamber, an igniter disposed in the combustion chamber, a driving mechanism actuated to perform a predetermined operation by utilizing a combustion pressure generated when the fuel is burned in the combustion chamber and an actuator that operates the fuel supplier and the igniter in one operation. Based on the operation of the actuator, fuel is supplied into the combustion chamber via the fuel supplier and the igniter performs ignition in relation to the pressure of the fuel supplied into the combustion chamber changes. According to the invention, because the fuel supplying and ignition can be done by the actuator in one operation, ignition can be performed in constant timing after fuel is supplied via the fuel supplying means.

Abstract: A file input/output control device for dividing a file into a plurality of fragments which are distributed to a plurality of storage devices. The file input/output control device 200, upon receiving a file from a client, constructs a plurality of fragments from a file with reference to a predetermined number of divisions and redundancy. The file input/output control device allows the fragments to be stored on a single storage device, but distributes fragments to the storage devices to avoid sending a single type of fragment to any one storage device, and to avoid sending all types of fragments to any one storage device, thereby ensuring security.

Abstract: A combustion power tool having a first combustion chamber, a second combustion chamber, an igniter, a partition, and a driving mechanism. Flammable gas is introduced or charged into the first and second combustion chamber. The igniter is disposed in the first combustion chamber. The partition separates the first combustion chamber from the second combustion chamber. Communication holes are formed in the partition at different angles with respect to the longitudinal direction of the first combustion chamber. The communication holes communicate the first combustion chamber with the second combustion chamber. The driving mechanism performs a predetermined processing work by utilizing an explosive combustion pressure.

Abstract: In a technology for dividing a file into a plurality of fragments which are distributed to a plurality of storage devices, to maintain a high level of security and fault tolerance, while storing the file on fewer storage devices than in the past. A file input/output control device 200, upon receiving a file from a client 100, constructs a plurality of fragments from a file with reference to a predetermined number of divisions and redundancy. A file input/output control device 200 allows a plurality of fragments to be stored on a single storage device, but distributes fragments to storage devices 300 in such a way as to avoid sending a single type of fragment to any one storage device, and to avoid sending all types of fragments to any one storage device. By so doing, file input/output control device 200 ensures security against cracking and system fault tolerance, while enabling files to be stored on fewer storage devices than in the past.

Abstract: Information such as a last scan time and a last update is encrypted and added to a file system that a CPU 132 on a host computer 13 manages. In accordance with the information, host 13 and a scan server work cooperatively. A scan is omitted for a file that is dated earlier than the last scan time, accelerating file access. When a file to be accessed is virus-infected, the user causing the virus infection is specified. Predetermined countermeasures can also be taken.

Abstract: A computer system in which a host computer is connected to a storage unit, the storage unit operating in a unit of a file. A file attribute control unit and the storage unit execute the processing being linked together so that, in response to a request from a client computer, the host computer executes a file attribute control program to add a particular attribute to the file, and that the storage unit operates in response to the attribute that is added.

Abstract: Time information from a time server may be incorrect because of human mistakes or cracking. This may cause time errors of one year or more and then data recorded in a storage device might be altered or deleted before their retention periods expire, which would lead to serious troubles. Provided is a storage system including: a plurality of time servers that distribute time information; a time server management device that obtains the time information from the plurality of time servers and selects a most reliable time server; and a file management device that make a decision as to whether a retention period of the data recorded in the storage device ends after the time obtained from the most reliable time server and prohibits alteration and deletion of the data depending on the decision.

Abstract: The present invention provides a loop optimization method and a compiler suitable for improving the execution time of a loop including assumed-shape array. A loop optimizer detects the outermost loop included in a subroutine, then traverse every statements in the outermost loop (including any inner nested loops) to detect array reference to the assumed-shape arrays to register thus detected assumed-shape arrays to the assumed-shape array table. Then for thus registered assumed-shape arrays, the optimizer generates a conditional expression determining whether the first order dimension stride of each array is 1 or not, to form a conditional statement by concatenating the conditional expressions of every elements registered to the assumed-shape array table with the conditional “AND” and then duplicates the loop by copying the outer loop and the loop body entirely in focus at that time to the part to be executed when the condition is TRUE and to the part to be executed when the condition is FALSE.
