IPC: G01P3/487
Filed: 1992-10-16
Abstract: PURPOSE:To provide a magnetic sensor with high resolution and at low cost without increasing the number of gears of a rotary body and the number of magnetic resistance elements. CONSTITUTION:A first and a second magnetic resistance element bridge 18, 19 are arranged with the phase difference of 90 degrees. An output Va=Asinomegat, Vb=Asin(omegat pi/2) from the bridges 18, 19 is added to a reduction circuit 4 having an oscillation or amplitude control means R1-R9, an adding circuits 5, 6, 7 to output a voltage Vc=Asin(omega t-pi/4), Ve=Asin(omegat+pi/4). These voltages Vc, Ve have the phase difference of 45 degrees with respect to the voltages Va, Vb. The output waveform of four phases with the same amplitude is obtained accordingly from two pairs of bridges which provide the same resolution as four pairs of bridges. It is thus possible to have high resolution with the minimum number of magnetic resistance elements, and to thereby provide a low current consumption and low cost magnetic sensor.

Abstract: PROBLEM TO BE SOLVED: To prevent the development of unnecessary casting flash by cast- forming continued band-state ridge projecting part along the surface part of a cast parts set to a position of a mating surface between a cope and a drag. SOLUTION: The cast parts 1' is cast by using the cope and the drag. The continued band-state ridge projecting part 18 is cast-formed from the inside to the outside of the cast parts 1' along the mating surface part (virtual line B-B position) of the cope and the drag. Since the ridge projecting part 18 is projectingly formed, the unnecessary casting flash is not developed. A cross sectional shape in the direction crossed at the right angle to the band-state direction of the ridge projecting part 18 is formed as hill-state and the height and the width of lower part are few mm size. The casting flash is not developed and the removing process of the casting flash is unnecessitated. The ridge projecting part 18 is continued as the band-state, and since this height and width are small sizes, a beauty of the cast product 1' is compared as a part of the design.
