Title: Magnetic circuit using anisotropic magnet
Inventor: KENMOCHI KATSUE
IPC: H01F3/10
Filed: 1979-07-16
Abstract: PURPOSE:To attain a high magnetic flux density, by providing shielding members on planes perpendicular to and parallel with the direction of the orientation of a shaped anisotropic magnet piece and using the shielding member on the parallel plane as a mangetic pole. CONSTITUTION:Anisotropic magnets 5 are oriented in the S-N direction and surround a shielding member 6 made of a cold-rolled steel plate. Another shielding member 7 made of the same material is in contact with a plane perpendicular to the direction of the orientation of the magnets and is also in contact with the former shielding member 6. The magnets are nylon resin magnets containing powder of anisotropic ferrite. According to this constitution, little magnetic flux leaks from the faces parallel with the direction of the orientation because the direction of easy passage of magnetic lines of force is limited. Since the surfaces of the shielding member 6 and the magnets 5 are near each other, the modulus of permeance of a magnetic flux generation space is increased and a high magnetic flux density is attained.

Abstract: PROBLEM TO BE SOLVED: To prevent as much as possible the generation of clock skew, even when fluctuation due to a process is present by allowing a DLL circuit to output a clock signal for obtaining a phase difference between a reference clock signal and a clock signal from the other edge of a wiring part as a prescribed value. SOLUTION: A DLL circuit 5 of each functioning block receives a reference clock f0 and a clock signal from a clock output terminal 9, generates a clock signal having a constant delay amount with respect to the reference clock f0 , and transmits it to a clock input terminal part 6. Thus, adjustment is operated so that the rising edge of a terminal clock can be made to coincide with the rising edge of the reference clock f0 , that is, the terminal clock can be delayed for a constant cycle from the reference clock f0 . Thus, the phases of the reference clock f0 inputted to each functioning block 3i (i=a-b) and the terminal clock can be made zero. Therefore, the generation of clock skew can be prevented as much as possible, even when process fluctuations on the like are present.
