Abstract

A Hall effect device provided with input terminal sections at both ends and output terminal sections, which are projected, at both sides of the center wherein at least one through hole is provided at a position near the side edge of at least one terminal section and is opened by cutting the side edge of the device so as to adjust unbalanced voltage.

Claims

1. A Hall effect device comprising a. a Hall effect member including a central portion having a pair of ends and a pair of sides, a pair of input terminal sections provided at said pair of ends and a pair of output terminal sectioNs provided at said pair of sides, b. a pair of input electrodes connected to said pair of input terminal sections, and c. a pair of output electrodes connected to said pair of output terminal sections, and d. a plurality of through hole means in at least one of said terminal sections, for altering the resistance of the current path betwen at least one of said input terminals and one of said output terminals thereby balancing the voltage of said Hall device, said hole means adjacent but spaced from the connected electrodes, at least one of said hole means being positioned near a side edge of said terminal section.

2. A Hall effect device according to claim 1, wherein two of said hole means are positioned near the side edges of said terminal section and a plurality of said hole means are positioned in parallel between said two hole means.

3. A Hall effect device according to claim 2, wherein the sizes of said hole means are gradually smaller in the sequence from the side edge of the terminal section to the inner part of the terminal.

4. A Hall effect device according to claim 2, wherein the distance between said hole means is gradually narrower in the sequence from the side edge of the terminal section to the inner part of the terminal.

5. A Hall effect device according to claim 1, wherein one of the output terminal section is made wider than the other so that its center line deflects to the one of input terminal sections and at least one hole means is provided thereon.

6. A Hall effect device according to claim 1, wherein thin and long hole means are provided in the direction of current flow.

7. A Hall effect device according to claim 1, wherein the terminal section is cut off at both sides of the section to form a neck shaped base with a straight line formed on the main part of the device.

8. A Hall effect device according to claim 1, wherein the center line of a pair of output terminal sections are shifted in opposite directions with respect to the center line of the device and the plurality of said hole means are positioned in parallel at said output terminal sections on the wider portion thereof with respect to the center line of the device.
