    摘要: A variable focus lens device having a temperature compensation function whose construction is simple and which can be inexpensively manufactured. The device has a lens member including a lens container having a transparent elastic film, a transparent sealing member forming an internal volume, and a transparent liquid filling the internal volume, a stack-type piezoelectric actuator for varying the focus of the lens member by deforming the transparent elastic film by fluctuating the pressure inside the internal volume, and a tank connected to the internal volume by narrow passages. The tank and the narrow passages absorb temperature fluctuation components of the transparent liquid, which varies due to thermal expansion and contraction. The tank and the passages thereby form a temperature compensator, that, because the passages are narrow, does not react to sudden oscillating pressure components caused by the stack-type piezoelectric actuator.

    摘要: A total-focus imaging apparatus comprises a variable-focus lens unit with a focal position thereof changeable at high speeds, a CCD element, a microcomputer and a liquid-crystal display unit. The microcomputer includes an image memory, an image processing circuit and a control circuit. The variable-focus lens unit and the CCD element allow an object of observation to be photographed to generate a number of images with the focal positions thereof slightly different from each other and the image to be stored in the image memory. Pixels each brought to a focus are selected by the image processing circuit from pixels of the images to generate an image of the observation object comprising only pixels each brought to a focus. Such an image is then displayed on the liquid-crystal display unit. Thus, an image of the observation object which is all but completely brought to a focus can be presented in a semi-real-time manner. An image of an observation object all but completely brought to a focus is an image with all portions of the observation object brought to a focus.

    摘要: A scanning apparatus includes a mirror coupled to a base via a spring portion, and a light source for emitting a beam toward a reflecting surface of the mirror so that the beam is incident thereon. The mirror reflects the beam from the light source and rotationally swings under a resilient force of the spring portion when a force is applied thereto. The reflecting surface of the mirror includes a plurality of mirror surfaces at different angles. The beam from the light source is simultaneously reflected by the mirror surfaces at different angles.

    摘要: A plurality of grooves, each having a depth of 10 &mgr;m or more and arranged adjacent to each other, are formed at a predetermined portion of a semiconductor substrate where a passive element is formed. Then, a thermal oxidation treatment is performed to let an oxide film grow from an inside surface of each groove so as to fill an inside space of the groove with a thermal oxide film thus grown and turn an entire portion intervening between adjacent grooves into a thermal oxide layer. Each groove has a width of 1 &mgr;m or less, and a width of a semiconductor material intervening between two adjacent grooves is 81.8% or more with respect to the groove width.
