    摘要： A steering wheel includes (a) a core member having a boss portion, a spoke portion, and a rim portion, the spoke portion stretching between the boss portion and the rim portion; and (b) a polyurethane member covering at least the rim portion of the core member, the polyurethane member having a specific gravity of 0.7 to 0.9 and a Shore A hardness of 45 to 60. A steering wheel proper defined as being a combination of the core member and the polyurethane member has a weight of 1.0 to 2.5 kg. This steering wheel is satisfied in both of weight reduction and maintenance of moment of inertia necessary for steering wheel.

    摘要： A method and system for writing data which includes the steps of: receiving a write command, storing associated data in a buffer memory, determining whether or not enough free space exists in the buffer memory to store a subsequent unit of write data, and sending a “command complete” signal to the external device, if it is determined that there exists enough free space to store a subsequent unit of write data. The disk drive unit includes: a random access recording medium, a command memory, a buffer memory, and a logic circuit for determining whether or not enough free space exists in the buffer memory to store a subsequent unit of write data, with a predetermined reference value representing the amount of free space occupied by a typical unit of write data.
