  • Patent number: 11507284
    Abstract: According to one embodiment, a storage device includes a nonvolatile storage medium and a controller. The controller encrypts data with an encryption key, writes encrypted data into the storage medium, and manages a first and second encryption keys. The first encryption key encrypts data to be written into a first area and a second encryption key encrypts data to be written into a second area. The controller updates, if the first area is write protected and the second area is not write protected, the second encryption key without updating the first encryption key when receiving an initialization command from a host.

  • Patent number: 11232044
    Abstract: According to one embodiment, a data storage apparatus includes a controller with a data protection function. The controller manages first and second personal identification data. The first personal identification data only includes authority to request inactivation of the data protection function. The second personal identification data includes authority to request inactivation of the data protection function and activation of the data protection function. The controller permits setting of the first personal identification data, when the second personal identification data is used for successful authentication and the first personal identification data is an initial value, or when the data protection function is in an inactive state.

  • Patent number: 10938283
    Abstract: An assembling device (10) includes a first arranging section (11), a second arranging section (12), eighteen support arms (13) for supporting coil segments (4), a feeding part (14), and a controller (16). When the controller (16) drives a motor (35) to rotate the feeding part (14) in a counterclockwise direction D1, a pressing roller (14c) rolls in the direction D1 along a first guide portion (11a), and presses a base part (21) of the eighteenth support arm (13) in the direction D1. Thus, the first to eighteenth support arms (13) are rotated in the direction D1 to insert the base parts (21) of the first to eighteenth support arms (13) sequentially in a second guide portion (12a) of the second arranging section (12), so that the first to eighteenth support arms (13) are rotated in a clockwise direction D2 to assemble the coil segments (4) while overlapping with one another.

  • Patent number: 10698838
    Abstract: According to one embodiment, a data storage apparatus includes a processor. The processor protects data on a memory by encryption in a first mode or a second mode. The processor stores a first image, a second image and a third image. The first image reproduces a first state which is an initial state where the data storage apparatus is set to neither the first mode nor the second mode. The second image reproduces a second state which is an initial state in the first mode. The third image reproduces a third state which is an initial state in the second mode. The processor is capable of performing a first process to transition from the first state to the second state, and performing a second process to transition from the first state to the third state.
