Patent JP-H05142069-A (JP)
Title: Distortion detector
Inventor: OZAWA HIROMASA
IPC: G01L3/10
Filed: 1991-11-26
Abstract: PURPOSE:To prevent the influences of the external magnetic field to a detecting coil through a driven shaft by using a non-magnetic, non-conductive material for the driven shaft. CONSTITUTION:When the torque is impressed to a driven shaft 1 from outside, a tensile force is generated at one of magnetic layers 3, 4 made of a material of high magnetic permeability, and a compression force is generated at the other layer, resulting in a distortion of the shaft. As the distortion is generated, the magnetic permeability is changed. The magnetic permeability is changed in opposite directions between when the tensile force is generated and when the compression force is generated. Detecting coils 10, 11 detect the change of the magnetic permeability as the change of the magnetic impedance, and the outputs of the detecting coils 10, 11 are input to a detecting circuit 14. The detecting circuit 14 generates a detecting voltage V corresponding to the amount of the distortion of the driven shaft 1. Since the driven shaft l is formed of a non-magnetic, non conductive material, the external magnetic field never influences the detecting coils 10, 11 through the driven shaft 1. Accordingly, the output is not fluctuated by the external magnetic field.

Title: Magnetoresistance magnetic sensor
Inventor: JIYANNMARUKU KUUTOURIE
IPC: G11B5/39
Filed: 1994-12-14
Abstract: PURPOSE: To improve sensitivity required for a magneto-resistive sensor by notching an area overlapped with the magnetic pole piece of the magneto- resistive element and concentrating currents flowing in the magneto-resistive element to the inner part of an area on the inner side of a clearance between the two magnetic pole pieces. CONSTITUTION: The magneto-resistive element is formed in a multistory tower form and the two parts of the magnetic pole pieces overlapped on the magnetic pole pieces with a distance (r) are constituted by a series of multistory tower- like elements 6. The elements 6 are arranged so that current I flows only in the parts position in the clearance of the magneto-resistive element. The width of the multistory tower-like elements is L and the interval of the two continuous multistory tower-like elements is desirable to be L. Then, current is limited to only an area where magnetic fields are concentrated. When the clearances are overlapped with 100μm width and (r) is 10μm, for example, the sensitivity gain of the magnetic resistance sensor becomes higher than the magnetic flux resistance sensor without the conventional multilayer tower-like element by about 20%.

Title: Bus interface device
Inventor: ARAI TAKASHI
IPC: G06F13/36
Filed: 1995-11-29
Abstract: PROBLEM TO BE SOLVED: To immediately restart repeating operation without performing initialization again after resetting during the repeating operation by providing an initialization information storage part, resetting the respective parts in the device once an entirety reset signal is received, and resetting the respective parts except the initialization information storage part when a partial reset signal is received. SOLUTION: A register 41 for initialization in a control register 4 holds control information which is set when a bus interface is started up and other control registers 42 hold control information altered according to the operation and state of the bus interface. Then the entire reset and partial reset signals of two systems are inputted from outside; and the respective constitution parts are all reset with the entire reset signal and the respective constitution parts except the register 41 for initialization are reset with the partial reset signal. Therefore, when a fault occurs during the repeating operation or when the system is debugged, the partial resetting is performed to evade the repetition of the initializing operation and the repeating operation can be restarted immediately after the resetting is reset.
