    摘要: A method for designing a base includes (1) selecting a location of a first center of expansion of a child part (CEchild) relative to a parent part; (2) determining a location of a second center of expansion of a bond joint (CEbond) bonding the child part to the base; and (3) determining a location of a third center of expansion of the base (CEbase) on a centerline, which is defined by the CEchild and the CEbond, so the CEchild does not substantially move relative to the parent part under a temperature change. To determine the location of the CEbase, the method further includes (a) determining a length change to the child part from the CEbond to the CEchild under the temperature change; (b) determining a length of the base that produces the same length change under the temperature change; and (c) locating the CEbase at the length away from the CEbond.

    摘要: Optronic tracking and guiding instruments are maintained in a readiness state by simulating various conditions including mechanical loads and, possibly, temperature variations for obtaining a set of corrective data which is then used for compensating possible errors during a real live mission. The compensation involves particularly focusing and exposure time control.

    摘要: A displacement generation device includes: a bimorph piezoelectric vibrator for receiving an externally applied drive voltage and for generating a displacement in response to the drive voltage; and a temperature-compensation capacitor element electrically connected in series with the piezoelectric vibrator. The capacitor element has a capacitance with a temperature coefficient with the same absolute value but opposite sign to that of the capacitance of the piezoelectric vibrator. When the capacitance of the piezoelectric vibrator changes in accordance with a change in the ambient temperature, the capacitor element properly changes the drive voltage supplied to the piezoelectric vibrator, thereby compensating for the displacement of the piezoelectric vibrator caused by the change in ambient temperature.

    摘要: To provide an excellent optical information recording method, optical information recording medium and optical information recording apparatus both of which use the method. The method generates no excessively-exposed region, can sufficiently fix recorded information, and never reduce the sensitivity of non-recorded regions. This is achieved because the method applies a fixing beam onto at least a portion of an exposed region of a recording layer of the optical information recording medium, the recording layer recording information by holography, at an exposure level T (mJ/cm2) that satisfies the condition H

    摘要: Apparatus with a multi-axis mechanism to perform, say, measurements or tests, has at least one pair of temperature detectors individually for each of selected members of the mechanism, each pair of temperature detectors being arranged to sense temperature differences transversely across the associated member. The required positions of the temperature detectors are predetermined from a preliminary examination of the mechanism, so that the extent and direction of each predetermined aspect of thermal distortion within the mechanism, can be computed from simultaneously detected transverse temperature differences, employing algorithms devised as a result of the preliminary examination of the mechanism. Compensation for corresponding selected errors in the measurements or tests can be calculated from the computed extent and direction of each of the predetermined aspects of thermal distortion within the mechanism.

    摘要: A temperature compensation system and technique requiring no measurement of actual temperature differential and wherein each source of thermal error in an electronic circuit can be corrected in addition to overall thermal error. Two reference voltages are provided having equal and opposite temperature response and having a null value at selected normal temperature. A respective correcting voltage is derived from the two reference voltages for each source of thermal error and each of magnitude and polarity to compensate for the corresponding thermal error. A correcting voltage can also be derived for compensation of overall residual thermal error.
