Title: Clock switching circuit
Inventor: SUGAWA AKIRA
IPC: G06F1/06
Filed: 1992-12-17
Abstract: PURPOSE:To provide the clock switching circuit for switching the clock of a CPU with interruption and reducing power by selecting a clock generating circuit for which the more the number of times of interruption is increased, the higher the frequency is increased. CONSTITUTION:When an interruption request is permitted and the interruption is generated, an interruption counter is incremented. A comparator circuit 4 respectively compares the number of times of interruption at an interruption time counter 2 with an interruption time comparative value for selecting clocks at frequencies n1-n3, and the comparator circuit with coincidence generates select data. The clocks are outputted from clock generation circuits 51-53, to which the signal is inputted, to a multiplexer 6. The multiplexer 6 selects the clock at much higher speed from any one of clock generation circuits 5 and supplies the high-speed clock signal to a CPU 1. When interruption processing request signals are inputted while being overlapped during the interruption processing, the number of times of interruption counted by the interruption time counter 2 is increased, and the clock is switched to the clock at much higher speed.

Filed: 1996-12-03
Abstract: PROBLEM TO BE SOLVED: To provide a magnetic head which is capable of improving productivity by preventing such a trouble that coils or lead wires are short-circuited with a back core without providing the coils with a bobbin. SOLUTION: A back york 3 including the back core 25 which constitutes a magnetic head core 26 by being joined with a front core 6 is manufactured with a Ni-Zn system ferrite with a volume electrical resistance of >=10[MΩ.cm] and an initial permeability of >=500×4±×10<-7> [H/m]. The back core 25 (back york 3) is made of the Ni-Zn ferrite and has high volume electrical resistance, and thus continuity between the coil 4 for recording and reproducing and the coil 5 for erasing, or the lead wires 4a, 5a and the back core 25 is prevented. Consequently, the bobbin which has been required in the conventional technique is eliminated or the application of special electrical insulation is no longer necessary. Further, the magnetic resistance of the back core becomes small by setting the initial permeability of >=500×4π×10<-7> [H/m], whereby sufficient head efficiency is obtained.
