摘要： To improve a response rate and an impact detection precision of an auxiliary acceleration sensor device for an air bag system, an auxiliary acceleration sensor device includes a longitudinal G sensor for sensing a longitudinal acceleration G of a vehicle, and lateral G sensor for sensing a lateral acceleration G of the vehicle. The longitudinal G sensor includes a constant current source circuit, a detector portion for outputting an electrical signal representative of a longitudinal acceleration G, and an amplifier portion for amplifying the signal received from the detecting portion. The comparator includes comparing elements that compare the voltage values corresponding to longitudinal threshold values Tf1 to Tf4 of the longitudinal acceleration G with an output signal of the amplifier portion. Lateral G sensor includes a constant current source circuit, a detector portion for outputting an electrical signal representative of a lateral acceleration G, and an amplifier portion for amplifying the signal received from the detecting portion. Comparator means includes comparing elements which compare the voltages corresponding to lateral threshold values Ts1 to Ts4 of the lateral acceleration G with the output signal of the amplifier portion. An OR circuit coupled for reception with the comparator means outputs a signal to a main controller of an air bag control system when predetermined conditions are satisfied.

摘要： A light-weight, highly rigid tool slide for a machine tool is provided which may be machined with a high degree of precision, whereby lateral play or "wobble" of the tool is reduced. The tool slide comprises an elongated slide member slidingly carried in a substantially cylindrical channel formed in the surface of a base member. A cover member covers both the channel and the slide member, which has a flat surface machined therein so as to conform to the shape of the covered channel. The channel in the base member may include an enlarged middle portion to reduce surface contact with the slide member and to provide space for lubricating material. A through-bore may be formed in the slide member to reduce its weight. An encoder monitors the rotational angle of a workpiece and drives a numerical controller and servomotor to move a cutting tool inward and outward in synchronism with the rotation of the workpiece. The numberical controller can be programmed to attain any profile on the workpiece including circular, and non-circular.

摘要： In a semiconductor acceleration sensor, a weight and thin beam parts adjacent to the weight are formed on a substrate, a moving electrode is formed on the weight, and a fixed electrode is formed at a position of the other substrate opposed to the moving electrode.

The fixed electrode or the moving electrode is formed with a projection toward the opposed electrode and the projection and the electrode come in contact with each other and conduct by action of acceleration with a predetermined spacing held between both the electrodes for preventing occurrence of chattering caused by the electrostatic attraction force between both the electrodes.

摘要： A small-sized, reliable, low-cost acceleration sensor includes a working mechanism having a large joint surface. In this respect, an acceleration sensor 1 is arranged so that a diaphragm portion 2D is formed on a (100) face of a plate of single crystal silicon. The four corner portions of the joint surface 2A of a square frame are expanded in the center direction of the plate of single crystal silicon so as to form expanded portions 2B. Moreover, the (100) face of the square plate of single crystal silicon is covered with a mask having at least an octagonal opening 10E before being subjected to anisotropic etching, so that the expanded portions 2B directed to the center portion are formed in the respective four corner portions of the plate of single crystal silicon.
