Inventor: WATANABE MASAO
IPC: G01C21/00
Filed: 1999-07-01
Abstract: PROBLEM TO BE SOLVED: To provide a data transfer device which can deal with the extension of bus width without changing the number of its terminals even when the bus width is enlarged. SOLUTION: If the bus width of a 1st bus 1 of a data transfer device 13 is different from the number of connection bits set to the bus 1, a DMAC(direct memory access controller) having a bus width conversion function is built into a CPU 4 which is connected to the bus 1. The CPU 4 serves as a bus master to the bus 1 and the device 13 serves as a bus slave to the bus 1 respectively. Then the device 13 transfers the data stored in a buffer memory 7 to a device 3 which is connected to the bus 1 via the CPU 4. Thus, the data can be transferred against the extension of width of the bus 1 without increasing the number of terminals of the device 13.

Abstract: PROBLEM TO BE SOLVED: To provide a silicon steel sheet used for an electric motor and an transformer, minimal in magnetic anisotropy and excellent in dimensional accuracy after blanking. SOLUTION: This steel sheet has a composition consisting of <=0.01% C, <=3.5% Si, 0.15-2.0% Mn, 0.015-0.035% S, <=2.0% Al, and the balance Fe with inevitable impurities and satisfying Mn(%)/S(%)>=10 and also has a structure where, among the Mn- and S-containing inclusions in a cutting plane cut perpendicularly in a direction parallel to rolling direction, the number of those in which a value obtained by dividing the maximum grain size of a grain by the minimum grain size is 1-10 and the maximum grain size is 1-50 μ is regulated to (1 to 50) pieces/mm<2> .  Because of the minimized shape anisotropy of the Mn- and S-containing precipitates in the steel sheet, practically no differences in the ratio of fractured surface due to differences in blanking direction are brought about and differences in residual stress due to the difference in blanking direction are minimized, and as a result, excellent dimensional accuracy after blanking is provided. Moreover, the texture is inhibited by the Mn- and S- containing precipitates and magnetic anisotropy can be inhibited, and the steel sheet can be suitably used for purposes, such as a compact motor, requiring precise working dimensional accuracy and uniform magnetic properties under multi-directional excitation conditions.
