    摘要: A device for controlling an electromechanical transducer such as a proportional electromagnetic valve, in which a pulse signal having a constant period shorter sufficiently than the minimum response time required for the displacement of the plunger of the proportional electromagnetic valve over its predetermined full stroke is applied to the electromagnetic coil of the proportional electromagnetic valve to superpose a very small vibratory stroke component on the stroke of the plunger, and the duty cycle of the pulse signal applied to the electromagnetic coil is varied so as to urge the plunger in directly proportional relation to the variation of the duty cycle without substantially giving rise to mechanical hysteresis in the stroke of the plunger.

    摘要: An apparatus which comprises a detector for detecting the density of one component (oxygen, for example) of exhaust gases from an internal combustion engine for regulating the ratio of air to fuel based on the detected value of the component in such a manner that the air-fuel ratio can be made approximate to the theoretical air-fuel ratio. The apparatus further comprises a first comparator having a hysteresis range and a second comparator having no hysteresis range for detecting the output of the detector for detecting the density of one component of exhaust gases, in order that variations in the characteristics of the detector or changes in its characteristics with time can be compensated for.

    摘要: A capacitance acceleration sensor and method of making same are disclosed. A capacitance acceleration sensor includes a movable electrode etched from a silicon plate which is clamped between two solid dielectric plate members of glass, silicon oxides, or oxygen oxides. Static electrodes are secured to surfaces of the dielectric members facing opposite the movable electrode, thereby providing easy manufacturing assessibility for leadout wires from these electrodes. In certain embodiments, the movable electrode is formed integrally with a monocrystalline silicon plate member which also contains an integrated circuit for generating an output acceleration signal in response to movement of the movable electrode when the assembly experiences acceleration forces.
