Abstract: A control data about the devices constituting the synchrotron are formed by an initial acceleration control data item, a plural extraction control data items, a plural energy change control data items connecting the plural extraction control data items, and a plural deceleration control data items corresponding to the plural extraction control data items. An affected part position detection unit and an extraction permission determination unit are provided to determine whether the position of a marker shown in transparent image information is included within a beam irradiation permission range. If the marker position is found included, the extraction permission determination unit outputs to an interlock system an extraction permission determination signal permitting beam extraction.

Abstract: A particle beam therapy system is disclosed which includes: a synchrotron accelerating a charged particle beam injected from a pre-accelerator up to a predetermined energy level before applying a high-frequency voltage to an extraction device to extract the charged particle beam caused to exceed a stability limit; a beam transportation system transporting the charged particle beam extracted from the synchrotron up to a treatment room, and an irradiation device irradiating a patient in the treatment room with the charged particle beam in conformity to the patient's tumor shape. The synchrotron has functionality to accelerate or decelerate the charged particle beam successively to extract the charged particle beam at a plurality of energy levels during an extraction phase of the synchrotron, the beam transportation system further having functionality to block off an unnecessary charged particle beam extracted from the synchrotron during acceleration or deceleration.

Abstract: A particle beam irradiation system having a multi-energy extraction control operation that controls the extraction beam energy in a synchrotron within a short time, such that when the ion beam irradiation is halted, an operating cycle is updated within a short time and a dose rate is improved. To this end, operating control data for each of the devices constituting the synchrotron is constructed by multi-energy extraction control pattern data for controlling extraction of beams of a plurality of energy levels at one operating cycle, and a plurality of sets of deceleration control data that correspond to the extraction control of the beam of the plurality of energy levels. The devices are controlled by using the operating control data.

Abstract: There is provided a realtime processing software control method in which the priorities of plural states can be relatively described according to the necessities of realtime processing for the respective states, and design of state transitions and task priorities considering realtime property can be performed in the upstream design stage before specific execution times are clarified. For the respective states ([1]311˜[6]316) the control target equipment can take, realtime property flags (F1˜F6) indicating whether the processings in the respective states require realtime processing or not, and priority levels (P1˜P6) that are determined by the immediately preceding state and the current state, are set, and a task priority management unit (104) changes the priority of the task on the basis of the realtime property flag and the priority level, with the state transition of the control target equipment.

Abstract: A push-pull chain having a lock mechanism provided between inner links and outer links, which are rotatably coupled together by link pins, to thereby permit the mutual pivotal movement of both links to be restricted. The lock mechanism is provided to both links on an axial line parallel to each link pin. As a lock pin moves parallel on the axial line and it is fitted in both links, the mutual pivotal movement of the links is locked.
