In this time, an unsealing means 7 is formed further along the seal 5 at the back at the nearly position of the seal 5. And unsealing notches 8, 8 functioning as an unsealing start point at the time to peel the bag body by hands, are formed at the upper end seal part 3. In this bag for pillow-type package, when the bag body is opened along the unsealing means 7 and the seal 5 at the back is pushed down on the unsealing part 9, the unsealing part 9 is hermetically sealed at the seal 5 of the back and reclosed.

Abstract: PURPOSE:To detect the acceleration with high accuracy without being influenced by dark vibration of a car body of an automobile, etc., by moving a permanent magnet by inertial force caused by acceleration and detecting a range of the acceleration. CONSTITUTION:By combining a permanent magnet 3 and a Hall element integrated circuit 8', and the displacement is converted into a variation of magnetic flux density, and also, brought to electric conversion. That is, to the tip of a plate spring 1, the magnet 3 used as an inertial weight, as well is attached, and used as a cantilever being movable by using the other end as a supporting point. Also, the magnet 3 of the tip of the movable part has N and S magnetic poles in the moving direction, a variation of magnetic flux density generated by a fact that the magnet 3 moves by following up inertial force caused by acceleration is detected by a Hall element 8 fixed to the wall or a circuit 8', brought to magnetoelectric conversion and a signal is fetched. Subsequently, at the time when air moves through a small clearance between an end part of the spring 1 formed integrally with a weight 4 which moves by receiving inertial force caused by acceleration and a still side wall surface, damping force caused by viscosity of the air works, the amplitude is suppressed and reduced. Also, when it is not held in an amplitude level in a frequency band of a normal range, it can be attenuated by, for instance, adding an LPF to a final stage of an electronic circuit.
