Abstract: A radiation measuring device having a plurality of sensors configured to generate charges in response to the radiation includes a signal processing device. The signal processing device uses an signal generated by a proton beam irradiation device upon changing of beam energy and causes accumulation values of charges output from the sensors to be separately stored in a main control device for each value of the energy. The main control device calculates depth dose profiles for values of the beam energy from the accumulation values stored in the main control device and representing the charges. The main control device calculates a range of the beam for each of the values of the beam energy from the depth dose profiles, corrects the depth dose profiles for the values of the beam energy using a correction coefficient that depends on the range and sums the corrected depth dose profiles.

Abstract: Disclosed is a storage device using non-volatile semiconductor memory that achieves high performance and long life for the device. When managing the non-volatile semiconductor memory (2), physical blocks are classified into three types: scratch blocks (22), data blocks (23), and erased blocks (24). Data writing from a host device (3) is performed on the scratch blocks. When the number of empty pages within a scratch block becomes less than a predetermined number or no longer exists, the block is treated thereafter as a data block, and one of the erased blocks is newly assigned as a scratch block. If there are insufficient erased blocks, a block with relatively less valid data is selected from among the data blocks. After copying all valid data included in the block to a scratch block, the block is erased, and thus an erased block is acquired.

A table having two sizing unit attachment portions which are adjacent to each other in a lateral direction orthogonal to the extrusion direction. The table is provided at a device body so as to be laterally movable between a first position where one of the two sizing unit attachment portions is at a production position and the other of the two sizing unit attachment portions is at a standby position, and a second position where the other of the two sizing unit attachment portions is at the production position and the one of the two sizing unit attachment portions is at the standby position. A sizing unit for production configured to perform cooling and sizing in practice is detachably attached to one of the two sizing unit attachment portions at the production position to coincide with an extrusion line.

Abstract: A beam extraction process (interruption and restart) is appropriately performed when a failure occurs during irradiation of a spot group. A charged particle irradiation system includes a synchrotron 12 and a scanning irradiation unit 15 that scans an ion beam extracted from the synchrotron over a subject. The extraction of the ion beam from the synchrotron is stopped on the basis of a beam extraction stop command. Scanning magnets 5A and 5B are controlled to change a point (spot) to be irradiated with the ion beam, while the extraction of the ion beam is stopped. The extraction of the ion beam from the synchrotron is restarted after the change of the spot to be irradiated. When a relatively minor failure in which continuous irradiation would be possible occurs during irradiation of a certain spot with the beam, the extraction of the beam is not immediately stopped.
