Abstract: Disclosed herein is an image processing apparatus, in which an object image focused by a lens is split into a plurality of images by means of a light splitting section. These images are converted into image data items by a plurality of imaging devices which are arranged with their imaging area overlapping in part. The image data items are stored temporarily in an image storing section. A displacement detecting section detects displacement coefficients (rotation angle R and parallel displacement S) from the image signals representing the mutual overlap region of two images which are to be combined and which are represented by two image data items read from the image storing section. The position of any specified pixel of the image displayed is identified by the pixel signal generated by the corresponding pixel of any imaging device.

Abstract: A scanning tunnel microscope includes a piezo-actuator movable in a direction Z perpendicular to the surface of a sample and provided with a scanning probe projected downward from the bottom thereof. The scanning probe is moved in the direction Z by the piezo-actuator. The piezo-actuator includes a position measuring probe projected therefrom, parallel to the surface of the sample, from the lower end of one side thereof. A reference sample having concaves formed on a surface thereof at predetermined intervals is fixed to the piezo-actuator. When the scanning probe is moved in the direction Z, the position measuring probe is moved along the reference sample, so that tunnel current having a waveform which reproduces the shape of the concaved surface of the reference sample is detected. Thus, the moving distance of the scanning probe can be obtained from the waveform of tunnel current detected.

Abstract: In a probe for observing an ultrasonic image, which obtains the ultrasonic image of an object to be observed such as a body cavity by means of an ultrasonic transmitting and receiving means, a mechanical scanning operation of the ultrasonic transmitting and receiving means is performed by an ultrasonic driving means, and thus it is possible to obtain a good diagnosis image with no distortion and no flicker because noises of the driving means can be reduced.Therefore, an ultrasonic endoscope system and an ultrasonic video endoscope system etc. which utilize the probe mentioned above can display a good ultrasonic image and a good optical image.

Abstract: Liquid crystal eyeglasses include a detector for detecting a physical quantity which varies with the temperature of the liquid crystal, the orientation of molecules of the liquid crystal or a change in the refractive index of the liquid crystal. The voltage applied to the liquid crystal is controlled in accordance with an output signal from the detector, thus compensating for a change in the refractive index of the liquid crystal which is attributable to a temperature change and maintaining the refractive index constant.

Abstract: A reel shaft comprises a substantially cylindrical shaft body to be fitted into a reel hub of a tape cassette for rotating the reel hub. A plurality of elongate projections are formed at regular intervals along the circumferential direction on the outer peripheral surface of the shaft body, and extend at a predetermined angle to the axial direction of the shaft body. The elongate projections on the shaft body engage or mesh with engaging projections of the reel hub to rotate the reel hub, and to push the reel hub in one direction along the axial direction of the reel shaft as the shaft body rotates.
