摘要:
A method of preparing a forming limit diagram in press forming includes obtaining a forming limit curve by subjecting a surface of a metal plate to be press-formed to marking at a distance between reference points of 0.5-1.0 mm, bulging the metal plate with a punch having a top minimum curvature radius of 3-10 mm and measuring a maximum principal strain and minimum principal strain at a time of generating cracks on the surface of the metal plate at a top portion of the punch from a change of the marking.

In a charged particle irradiation system, forming a uniform dose distribution is required by irradiating a moving irradiation object through beam scanning and energy stacking. The charged particle irradiation system includes an ion beam generator 1 from which an ion beam is extracted with a target beam current value thereof set; an irradiation nozzle 21 having scanning magnets 23, 24 and an energy filter 26, the irradiation nozzle 21 for irradiating an irradiation object with the ion beam; and an irradiation object monitoring unit 66 for measuring a position of the irradiation object and outputting signals that vary with time according to displacement of the irradiation object. The charged particle irradiation system determines extraction timing of the ion beam based on the signal outputted from the irradiation object monitoring unit 66 and sequentially changes energies of the ion beam to thereby perform a repainting irradiation with each of the energies.

A particle irradiation apparatus and a particle beam irradiation method that controls the energy and irradiation dose of a particle beam to form a high dose region having a high uniformity of depth-directional spread (Spread Out Bracici Peak, referred to as SOBP). A SOBP having a steep falling edge of the dose distribution on the deep side from the body surface is formed based on a method of superimposing SOBPs each having a small dose distribution width to form a desired SOBP. An energy-spread-device forms a first SOBP having a small dose distribution width; and an energy spread device 2 forms a second SOBP having a small dose distribution width and a steep falling edge of the dose distribution at the deepest portion from the body surface. The thus formed SOBPs are superimposed to form a SOBP having a length suitable for the target region.

Restraining torque TF of an electronic controlled front limited slip differential (5) arranged between right and left front wheels is controlled in accordance with controlling right-left wheel rotational speed difference ΔNF, which is the rotational speed difference between the right and left front wheels, while restraining torque TC of an electronic controlled coupling (8) arranged between the front and rear wheels is controlled in accordance with controlling front-rear wheel rotational speed difference ΔNC obtained by subtracting ½ of the rotational speed difference between the right and left wheels (|ΔNF|/2) from the rotational speed difference (ΔNCT−ΔNCD) between the front and rear wheels.

The present invention provides, at low cost, a multilayer radiation detector whose position relative to a beam axis can be verified. The radiation detector includes a plurality of sensors that react to radiation and are stacked in parallel inlayers in a traveling direction of the radiation. The sensors are each sectioned into a central region including the center of the sensor and another region surrounding the central region. The radiation detector independently measures signals measured by the central regions and signals measured by the other regions. Thus, the position of the radiation detector can be verified.
摘要:
In a particle therapy treatment planning system for creating treatment plan data, the movement of a target (patient's affected area) is extracted from plural tomography images of the target, and the direction of scanning is determined by projecting the extracted movement on a scanning plane scanned by scanning magnets. Irradiation positions are arranged on straight lines parallel with the scanning direction making it possible to calculate a scanning path for causing scanning to be made mainly along the direction of movement of the target. The treatment planning system can thereby realize dose distribution with improved uniformity.

A differential limiting control device for a vehicle calculates a yaw rate correspondence control amount according to deviation between actual yaw rate and target yaw rate when a vehicle turns, and also judges the vehicle's steering characteristic of the moment and magnitude relation between wheel speeds of right and left front wheels. The differential limiting control device then applies compensation toward an increase or decrease side based on a yaw rate correspondence control amount to a base control amount according to a combination of the steering characteristic and the magnitude relation between the wheel speeds, and controls a differential limiting force between the right and left front wheels based upon a final control amount obtained after the compensation.
