Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
122 words
A Hall effect type sensing device, comprising: magnetic circuit forming means including a permanent magnet; a Hall transducing element arranged in a magnetic circuit formed by the magnetic circuit forming means; a frame body having a holding part for locating and holding the magnetic circuit forming means and the Hall transducing element in predetermined positions, the frame body being prepared by primary molding; and a protective compound encapsulating the magnetic circuit forming means, the permanent magnet, and the Hall transducing element together with the frame body to prevent any relative movement therebetween, the protective compound being prepared by secondary molding and defining a gap in the magnetic circuit forming means, a movable shutter, and said gap adapted to accommodate said movable shutter.
Claim 2
Dependent Claim
122 words
A Hall effect type sensing device, comprising: magnetic circuit forming means including a permanent magnet; a Hall transducing element arranged in a magnetic circuit formed by the magnetic circuit forming means; a frame body having a holding part for locating and holding the magnetic circuit forming means and the Hall transducing element in predetermined positions, the frame body being prepared by primary molding; and a protective compound encapsulating the magnetic circuit forming means, the permanent magnet, and the Hall transducing element together with the frame body to prevent any relative movement therebetween, the protective compound being prepared by secondary molding and defining a gap in the magnetic circuit forming means, a movable shutter, and said gap adapted to accommodate said movable shutter.
Claim 3
Dependent Claim
56 words
A Hall effect type sensing device according to claim 1, further comprising conductors inserted in the frame body for taking out an output signal from the Hall transducing element, and lead wires led out of the main body of the Hall transducing element, the lead wires being electrically connected to exposed portions of the inserted conductors.
Claim 4
Dependent Claim
35 words
A Hall effect type sensing device according to claim 2, wherein connections between the lead wires of the Hall transducing element and the exposed portions of the inserted conductors are surrounded by the protective compound.
