Abstract: A brake disc includes a disc body and a plurality of fins. The plurality of fins are disposed on one surface of the disc body such that each of the fins extends from an inner peripheral side toward an outer peripheral side of the disc body. Each of the fins includes two side surfaces and a top surface. Among the plurality of fins, at least one fin includes a plurality of protruding ridge portions. The plurality of protruding ridge portions are arranged in a radial direction of the disc body on at least one side surface of the two side surfaces of the fin. Each of the protruding ridge portions extends between the disc body and the top surface of the fin.

Abstract: A sealing device incorporated in a packaging machine heat-seals a vicinity of a bag mouth of a packaging bag. Paired heater bars are disposed opposite each other so as to be openable/closable and hold the vicinity between them when closed, thereby heat-sealing the vicinity. A link mechanism converts rotation of an output shaft of a servomotor to an opening/closing operation of the heater bars. A storage unit stores seal patterns, each of which includes a sealing pressure applied to the parts and a sealing time period for which the parts are continuously held. A selection unit is configured to select one seal pattern. The output shaft is rotated by a predetermined closing angle according to the sealing pressure of the selected seal pattern to close the heater bars. The heater bars are maintained in the closed state for the sealing time period of the selected seal pattern.

Abstract: A vibrating device is incorporated in a packaging machine to vibrate packaging bags filled with articles. The vibrating device includes a tapping plate disposed below the bags, a servomotor having an output shaft, a selection unit selecting one of vibration patterns set according to sizes of the bags or types of the articles, an output unit delivering data of a rotation pattern of the output shaft, and a control unit controlling the output shaft according to the rotation pattern based on the delivered rotation data. When one vibration pattern is selected according to the size of the bag or the type of the articles, the control unit controls the output shaft according to the rotation pattern corresponding to the vibration pattern, so that the tapping plate connected via a link mechanism to the output shaft is vibrated up and down in the selected vibration pattern to vibrate the bag.

Abstract: A therapy planning device includes: a condition acquiring unit configured to acquire therapy conditions including a position of an affected area, a necessary dose for the affected area, and a threshold dose for an area other than the affected area; a first planning unit configured to plan a first irradiation of irradiating a first irradiation field including the entire affected area to radiation; and a second planning unit configured to make a therapy plan satisfying the therapy conditions in combination of the first irradiation planned by the first planning unit and irradiation of an irradiation field including only part of the affected area.

Abstract: A radiation therapy planning apparatus includes a three-dimensional data collection part collecting three-dimensional data representing a plurality of positions where a plurality of portions of a subject are positioned, a marker position measurement part measuring a motion of a marker, and a dose calculation part calculating, when the subject is irradiated with therapeutic radiation changing on the basis of the motion of the subject, the dose of the therapeutic radiation with which each of the plurality of portions is irradiated, based on the motion and the three-dimensional data. The radiation therapy planning apparatus thus constructed can calculate the dose of the therapeutic radiation with which each of the respective portions of the subject is irradiated, more accurately, and reduce the dose of radiation with which the subject is irradiated in calculating the motions of the plurality of portions of the subject.
