Access control with easy change/extension is implemented. Access to data is controlled by a first storage unit that stores a plurality of attribute values respectively selected from a plurality of integers which are relatively prime and identifying a plurality of attributes of users, in association with respective users a second storage unit that stores a product of at least two attribute values which are common to users belonging to a set of users, in association with respective data to be accessed, to show the set of users which are targets of controlling access to the data. A plurality of attribute values corresponding to a user who requests access are read from the first storage unit, and a product of at least two of the plurality of read attribute values is calculated. The user is accepted as a target of controlling access to the data, on condition that the calculated product of attribute values matches a product of attribute values stored in the second storage unit in association with the data to be accessed.

When the diagnostic center position and a reconstruction FOV are designated using a tomographic image, a system control device controls a top plate of a table to move from side to side and up and down so that the designated diagnostic center position reaches the center position of scanning. A scanner is provided with a plurality of compensation filters configured to adjust X-ray irradiation distribution, and the system control device selects a proper compensation filter according to the designated reconstruction FOV from among the plurality of compensation filters, switching to the selected compensation filter. The compensation filters include at least a compensation filter (size L) of wide-width X-ray irradiation distribution and a compensation filter (size S) of narrow-width X-ray irradiation distribution in a scanner-turning direction. When the designated reconstruction FOV is a predetermined threshold or less, the compensation filter is switched to the S-sized compensation filter.

Embodiments of the present invention relate to approaches to effectively let noise on a head slider bonded to a silicon substrate of a microactuator, escape to the ground. A head gimbal assembly (HGA) according to an embodiment of the present invention comprises a microactuator bonded to a gimbal tongue. The microactuator comprises a piezoelectric element and a movable part for moving in response to expansion or contraction of the piezoelectric element. The motion of the movable part causes a head slider to slightly move. The microactuator further comprises a conductive path including an impurity-containing silicon layer formed on the silicon substrate. The conductive path transmits electric charge of the head slider to a suspension. The conductivity of the impurity-containing silicon layer is lower than the one of the silicon substrate so that the noise charge of the head slider may escape to the suspension.
