摘要： Light waves are allowed to pass clockwise and counterclockwise through a circuit optical path of at least one loop, and the light waves having passed through the optical path are interfered with each other. Phase modulator is inserted in one end of the circular optical path, by which the light waves are phase modulated. The intensity of the interference light is detected, as an electric signal, by a photodetector. The fundamental wave component of the modulation frequency of the phase modulator, contained in the electric signal converted by the photodetector, is synchronously detected by a first synchronous detector, from which is output a signal corresponding to an input angular velocity. Second and fourth harmonic components of the modulation frequency of the phase modulator, contained in the electric signal, are synchronously detected by second and third synchronous detectors. The phase modulator is controlled so that the ratio between the outputs from the second and third synchronous detectors is always equal to a preset reference value.

摘要： A temperature-compensating circuit for a capacitive or prezoelectric resistive accelerometer comprising a flexure with torquer coils subjected to physical changes in response to the linear accelerations, capacitive or piezoelectric resistive elements for detecting strain of the flexure, elements for amplifying the detected output and a negative feedback amplifier for supplying the output to the torquer coils. The output of the piezoelectric resistive element and the resistance of the torquer coils are affected considerably by the temperature change whereby the gain of the feedback amplifier changes. Accordingly, in the circuit of the present invention, the temperature change in the total gain of the accelerometer is removed by adding resistance elements to the negative feedback amplifier so as to cancel the positive temperature coefficient of resistance of the torquer coil and other elements.

摘要： An accelerometer comprises a pair of stators, a permanent magnet arranged within each of the stators, arcuate support portions diametrically opposed to each other on the surface of each stator, a pair of ring members each of which is positioned on the arcuate support portions of a stator, and a support ring with a flapper interposed between the support ring members. The flapper is connected to the supporting ring by two hinge portions. On each side of the flapper is a bobbin on which a coil is wound, the coils being connected to an external circuit. All of the component elements of the accelerometer are constructed and designed so as to avoid stress depending upon a change in ambient temperature.

摘要： An accelerometer is composed of a pair of housings each of which forms a magnetic structure together with a permanent magnet and a flapper flexurally supported by hinge portions between the magnetic structures. The permanent magnet is secured to the housing of the magnetic structure by means of a spacer so as to prevent a harmful thermal stress which will be caused by the difference of thermal expansion between the magnet and the housing. A bobbin with a torquer coil is secured to the flapper by means of a base member to take no effect of thermal stress which will be caused by the difference between the materials of the bobbin and the flapper. The above elements are housed in a case which is installed in an instrument board so as to be unaffected by changes in temperature in surroundings of the accelerometer.

摘要： A zero insertion force type connector for connecting pins of an integrated circuit package, which comprised a housing having a plurality of recesses separated from each other by a partition, electrical contact terminals being mounted in the housing through an opening in the slider which is mounted in the recess. The contact terminal comprises a web, blade and terminal portion. The web is formed to provide a resilient body and the blade is provided with an opening which has an enlarged portion and a narrow slot. The web portion is driven by the slider to align the enlarged portion of the opening in the blade with the pin to be connected and when the web portion is returned to its original position, the pin is grasped in the slot and brought into contact with the contact terminal.
