    • In a magnetic head in which first and second core halves are disposed on the entry and leaving sides of a magnetic recording medium, respectively, one of the first and second core halves is provided with a first edge for limiting a data track width and second edges which are disposed on both sides of the first edge and are inclined by a first angle with respect to the first edge. The other core half is provided with a third edge which is opposed to the first edge and is equal in length to the first edge. The other core half is also provided with fourth edges disposed on both sides of the third edge and inclined by a second angle with respect to the third edge. The data recording is made in the magnetic field between the first and third edges. Furthermore, the recording is made on both sides of the data track by the magnetic fields between the second and fourth edges so that erasure of old data can still occur despite deviation of the positions of the new and old data tracks. On both sides, data which has an azimuth with respect to the data recorded on the data track is not reproduced and there is no adverse effect.
    • 在其中第一和第二半部分别设置在磁记录介质的进入和离开侧的磁头中,第一和第二半部中的一个分别设置有用于限制数据磁道宽度的第一边缘和第二边缘 它们设置在第一边缘的两侧并且相对于第一边缘倾斜第一角度。 另一个芯体半部设置有与第一边缘相对的第三边缘,并且其长度与第一边缘相等。 另一个芯半部还设置有设置在第三边缘的两侧并相对于第三边缘倾斜第二角度的第四边缘。 在第一和第三边缘之间的磁场中进行数据记录。 此外,通过第二和第四边缘之间的磁场在数据轨道的两侧进行记录,使得尽管旧的和旧的数据轨道的位置有偏离,仍然可能发生旧数据的擦除。 在两侧,相对于记录在数据轨道上的数据具有方位角的数据不被再现,并且没有不利影响。

    • A contactless ignition system for an internal combustion engine in which a moderately rising timing signal and a steeply rising auxiliary signal are generated so that an auxiliary thyristor is triggered by the auxiliary signal to be conductive to render a main thyrister which is connected in series with the auxiliary thyristor to be conductive by the timing signal and in which a resistor for holding the auxiliary thyristor in the conductive state is connected in parallel with the main thyristor so that the ignition timing in the high speed range may be controlled by the auxiliary signal to prevent the excessive spark timing advance in the high speed range and also in the low speed range the auxiliary thyristor may be maintained in the conductive state until the main thyristor is made conductive to thereby prevent misfiring.
