The four wings are bonded to a wing-bonding member including a cross-shaped center shaft so as to form a cross shape. The front end structural member and the wing-bonding member are made of a zirconium alloy. The wings include neutron-absorbing plates having neutron-absorbing portions and each have an outer surface which is opposed to a fuel assembly and at which a hafnium-zircaloy composite member covered with zircaloy is disposed. The neutron-absorbing plates are opposed to each other with trap spaces disposed therebetween.

摘要： A control device for an alternating current motor includes: a target current generating unit which generates a current order value, based on a torque order, as a d-axis target current and a q-axis target current on dq coordinates; a current detection device which detects an alternating current supplied to each phase of a polyphase alternating current motor; a coordinate transforming unit which transforms the alternating current detected by the current detection device into a d-axis current and a q-axis current on the dq coordinates; and a vector control unit which carries out a current feedback control so that the d-axis current follows up the d-axis target current and the q-axis current follows up the q-axis target current. The vector control unit further includes: an operation switching unit which, depending on whether a back electromotive voltage of the alternating current motor is greater than or equal to a predetermined value, calculates one of a d-axis deviation and a q-axis deviation from the deviation between the d-axis target current and the d-axis current and the other one of the d-axis deviation and the q-axis deviation from the deviation between the q-axis target current and the q-axis current; and an integration controlling unit which outputs a d-axis integration voltage order value proportional to an integral value of the d-axis deviation and a q-axis integration voltage order value proportional to an integral value of the q-axis deviation. An alternating current supplied to each phase of the alternating current motor is controlled based on an output of the integration controlling unit.

摘要： A stacker for storing a plurality of stimulable phosphor sheets has a plurality of stock plates defining a plurality of sheet bins for storing the stimulable phosphor sheets respectively therein. The stock plates are slidably supported on and between two holder members. One of the sheet bins is selected and relatively brought into confronting relation to a feed roller pair. The stimulable phosphor sheet stored in the selected sheet bin can be displaced toward the feed roller pair by displacing the stock plate which defines the selected sheet bin.
