A method for measuring spectrum by Fourier-transforming an interferogram of an infrared interference wave acquired with an interferometer, including a step of over-sampling intensity signals of the interference wave at positions (D1, D2, . . . ) of a movable mirror set on the basis of a wavelength &#x3bb;1 of a semi-conductor laser, and a step of interpolating intensity signals (I1', I2&#x2032;, . . . ) that would be obtained when the interference wave is sampled at positions (D1&#x2032;, D2&#x2032;, . . . ) of the movable mirror set on the basis of a wavelength &#x3bb;0 of a He&#x2014;Ne laser, by using the over-sampled intensity signals (I1, I2, . . . ), for calculating the spectrum with the interferogram based on the interpolated intensity signals (I1&#x2032;, I2&#x2032;, . . . ) and for an efficient use of conventional stored spectrum data which are measured based on the wavelength &#x3bb;0.

The invention provides a thread and counterfeit preventive paper satisfying the conditions that, when the micro-character of the thread is viewed from one side and opposite side of the paper or printed material, the image of micro-character can be recognized in the same direction from any side, not in opposite direction to each other, and that, when viewed from the opposite side, the image of the corresponding micro-character is not visible. The counterfeit preventive paper and counterfeit preventive printed material have a structure in which a thread having metal deposition layers formed in a pattern of micro-character and colored printed layers formed thereon provided on both sides of a strip-like and light permeable substrate is inserted between paper layers.

A focus adjusting device which includes an imaging unit, such as a lens group, a film, a charge coupled device, a CMOS sensor, etc., and at least one electrostriction unit deforming based on an applied voltage and configured to move the imaging unit from the deforming. Further, positioned between the imaging unit and the at least one electrostriction unit is a mechanism for increasing or accumulating the deforming of the at least one electrostriction unit. The electrostriction unit can take the form of a laminate piezoelectric device. In one specific embodiment, the mechanism provided between the imaging unit and the at least one electrostriction unit is a lever which increases the deforming of the at least one electrostriction unit. In another embodiment, at least two electrostriction units are utilized and the mechanism provided between the at least two electrostriction units and the imaging unit is a coupling between the at least two electrostriction units which accumulates the deforming of each of the at least two electrostriction units. According to a further embodiment, the mechanism provided between the imaging unit and the at least one electrostriction unit is an elastic member with curved portions which increase the deforming of the at least one electrostriction unit in a direction perpendicular to a direction of the deforming of the at least one electrostriction unit.

A compact camera has a zooming lens system for regulating a focal distance and a shutter blade member for opening and closing the lens system. The blade member is shifted forwardly from its rest position to open the lens system through a given shift amount effective to determine a lens aperture size to effect exposure, and subsequently is shifted reversely to close the lens system to return to the rest position. A driving mechanism is connected to the blade member to undergo a reciprocating stroke to drive the blade member forwardly and reversely to effect opening and closing of the lens system. The blade member and the driving mechanism are disposed on a substrate. An adjusting mechanism is disposed around the substrate. The adjusting mechanism includes a stopper member undergoing displacement in response to the zooming of the lens system. The stopper member acts on the driving mechanism to control the reciprocating stroke of the driving mechanism according to the displacement of the stopper member so as to limit the shift amount of the blade member to thereby effect adjustment of the lens aperture size according to the lens focal distance or the zooming. Generally, the adjustment is carried out such as the smaller the focal distance, the smaller the lens aperture size.
