摘要： An accelerometer, e.g. for use as an air bag trigger, has a casing 2, 3 having a center axis, and a pressure sensitive element 46 located at the bottom portion of the casing. A gel based medium 7 is accommodated in the casing. Given that "x" denotes a positional deviation of the pressure sensitive element with respect to the center axis of the casing and that "h" denotes a height of the medium in the casing, the positional deviation (x) and the height (h) are set such that the value 2x/h falls within a predetermined range and serves to determine the anisotropic sensitivity ratio of the sensor. The device can thus be made highly directional and its sensitivity adjusted by the depth 'h' of the gel or by the dispersion of heavy particles therein. No diaphragm is needed over the gel. The device is also stated to be resistant to being dropped.

摘要： PROBLEM TO BE SOLVED: To provide a magnetometric sensor capable of suppressing a change with time of an offset voltage.
SOLUTION: This magnetometric sensor 1 detects a change of the direction of a magnetic field based on a change of each electric resistance value of a plurality of magnetic resistance elements 11-14 corresponding to the change of the direction of the magnetic field. The magnetometric sensor 1 is provided with heat-treated parts 31a-34a, 41a-44a melted by application of heat corresponding to each of all the magnetic resistance elements 11-14 constituting the magnetometric sensor 1. Namely, when manufacturing the magnetometric sensor 1, the heat-treated parts 31a-34a, 41a-44a are provided prior to trimming.
