  • Acceleration sensor
    Patent number: 6055858
    Abstract: An acceleration sensor is composed of a three-layer system. The acceleration sensor and conductor tracks are patterned out of the third layer. The conductor tracks are electrically isolated from other regions of the third layer by recesses and electrically insulated from a first layer by a second electrically insulating layer. In this manner, a simple electrical contacting is achieved, which is configured out of a three-layer system. One exemplary application of the acceleration sensor includes mounting the acceleration sensor on a vibrational system of an rpm (rate-of-rotation sensor). This simplifies the manufacturing of an rpm sensor, since the vibrational system and the acceleration sensor are configured out of a three-layer system, wherein the conductor tracks are run into the frame of the rpm sensor in which the vibrational system is suspended, so as to allow excursion.

  • Method for the manufacture of silicon injection plates and silicon plates produced thereby
    Patent number: 5421952
    Abstract: A method for fabricating silicon injection plates is both highly precise and particularly simple. The silicon injection plate is formed by an upper silicon plate having injection holes and a lower silicon plate having a through opening and channels. The lower silicon plate is fabricated by simultaneous, double-sided etching of silicon.
