Abstract: A non-volatile memory device includes a non-volatile memory unit, a control unit, and an interface. The control unit receives a write request, determines whether data is an object of a write of sequential management when a write size of the received data is smaller than a management unit of erasure, performs first write processing in which the received data smaller than the management unit of the erasure is sequentially written when the data is the object of the write of the sequential management, and performs second write processing in which the received data smaller than the management unit of the erasure is written by the management unit of the write when the data is not the object of the write of the sequential management.

Abstract: High-speed data transfer is performed in a storage device having a plurality of semiconductor memories while an increase in power consumption is prevented. In a memory controller, a request transfer unit transfers a request for demanding transfer of data and data based on the request to each of a plurality of memories in synchronization with a clock signal. A busy time measurement unit measures a busy time which is a time required for access based on the request, for a selected memory which is one memory out of the plurality of memories. A clock signal adjustment unit substantially equalizes the measured busy time of the selected memory and a total time required for transferring the requests and the data for the plurality of memories except the selected memory by adjusting a frequency of the clock signal.

Abstract: When disassembling after a gas being supplied into a tube member, the gas in the tube member is discharged before the tube member and a moving member become separable. In a webbing take-up device, a cover plate cannot be removed from a frame and thereafter a cylinder and a piston inside the cylinder cannot be separated before covering of a fixing screw with a covering section of a plate being released by removing a screw from an exhaust port of the cylinder and by removing the plate from the cylinder. Thus, after a high-pressure gas being supplied into the cylinder, the high-pressure gas inside the cylinder can surely be discharged by removing the plate from the cylinder and the exhaust port is opened by the screw before the cylinder and the piston being separated.

Abstract: In a pretensioner mechanism, movement of a piston is anchored by an anchoring pin. The anchoring pin is crushed and the piston is allowed to move. Hence, a pinion is turned by a rack of the piston. A facilitating cavity is formed in the anchoring pin. Crushing and deformation of the anchoring pin in a diametric direction thereof due to a movement of the rack is facilitated by the facilitating cavity. Therefore, the anchoring pin may be easily crushed and deformed in the diametric direction by the movement of the rack, and the action of the anchoring pin caused by the movement of the rack may be effectively made consistent.

Abstract: A pretensioner comprising a gas generating unit; a pretensioner body to whose inside the gas is supplied; a spool driving member disposed inside the pretensioner body and causing a spool to rotate to retract webbing onto the spool; a gas flow rate adjusting portion disposed in the spool driving member and whose inner peripheral shape is set in accordance with a flow rate of the gas to be passed through the gas flow rate adjusting portion; and a filter unit having a vent portion that is communicated with a space between the gas generating unit and the spool driving member and is also communicated with the gas flow rate adjusting portion. The open shape of the gas flow rate adjusting portion has a portion that does not coincide in a plan view with the open shape of the vent portion, and the overall open area of the vent portion is set larger than the open area of the gas flow rate adjusting portion.

Abstract: In a webbing retractor, the center of a rack and rack-teeth in an axial direction of a pinion is placed on the opposite side of a leg plate side with respect to the central axis of a cylinder. The piston is acted upon by a tilting-force toward the leg plate side from the pinion. A stop portion of an upper stay is placed on another leg plate side of the leg plate. Even when the piston is acted upon by the tilting force toward the leg plate side from the pinion, the stop portion can stop the movement of the leg plate toward the other leg plate side, and tilting of the piston and the cylinder toward the leg plate side can be suppressed. Moreover, the need to increase the strength of a frame and so forth can be eliminated, so the webbing retractor can be made compact and lightweight.

Abstract: A flash memory device includes a flash memory unit; and a control unit configured to perform control so that data having a size smaller than a block size of the flash memory unit is sequentially written to the flash memory unit.
