Abstract: A storage device includes a non-volatile storage, and a controller configured to carry out, in parallel, operations in response to a plurality of commands received from a host and queued in a command queue. When the controller detects an error in a first operation that is being carried out in response to a first command while the controller is in parallel carrying out a second operation in response to a second command, the controller continues to carry out the second operation until a predetermined condition is met while carrying out the second operation and, at that time when the predetermined condition is met, transmits an error event notification to the host.

Abstract: According to one embodiment, a memory system includes a memory, an encoding unit, an interface unit, a decoding unit and a changing unit. The encoding unit is configured to encode first data to generate second data. A size of the second data is equal to a first size. A size of the first data is equal to a second size which is smaller than the first size. The interface unit is configured to store the second data in the memory and to read the second data from the memory. The decoding unit is configured to decode the second data read from the memory to perform detection of an error. The changing unit is configured to change the second size according to an occurrence situation of the error.

Abstract: A disk storage device stores write data in a cache area of a data buffer according to a write command from a host, reports write completion to the host, and then writes the write data in the cache area to a storage medium. The disk storage device stores the write data stored in the data buffer in a save area created on the storage disk in response to the reception of a command which requires integrity, other than a write command, and reports a response to the host. Therefore processing time of this command and response time to the host can be decreased, while maintaining the safety of the write data.

Abstract: A sheet feed mechanism is disclosed which will permit manual feed as well as automatic seriatim feeding. The mechanism includes a main feed roller movable into and out of contact with the top sheet of a stack, another feed roll above and in contact with the main roller and a pinch roller above and in contact with the other roller to form a nip through which a sheet may be manually guided for feeding.

Abstract: A method and apparatus is disclosed for synchronizing copy substrate positioning with an image position on a photoreceptor in an electrostatic copier that includes primary rollers which drive intermittently at a slower speed than copier process speed while feeding a copy substrate to the photoreceptor. Secondary rollers which are located between the primary rollers and the photoreceptor drive the copy substrate continuously at the process speed. After the copy substrate enters the secondary rollers, the primary rollers stop driving and allow the copy substrate to continue in travel by the driving force of the secondary rollers in synchronism with the image on the photoreceptor.
