Abstract: A film with excellent corrosion resistance, alkali resistance, solvent resistance, and fingerprint resistance can be obtained by treating the surface of a metallic material with a water-based surface treatment agent comprised of a specified water-soluble resin or water-based emulsion resin such as a cationic or nonionic urethane, acrylic, epoxy, polyester, or polyamide resin, a phenolic resin-type compound with a specified structure, and a metal compound containing at least one metal selected from the group consisting of Zr, Ti, V, Mo, W, Mn, and Ce.

Abstract: A metal treating composition comprising at least a specific type of dissolved and/or dispersed organic resin, a dissolved vanadium compound in which the valence of vanadium is from 3 to 5, and a dissolved compound that contains at least one of the metals Zr, Ti, Mo, W, Mn, and Ce can provide metal surfaces with superior corrosion resistance, alkali resistance, and fingerprint resistance. The composition contains no chromium to cause pollution problems and/or require pollution abatement.

Abstract: In an apparatus for examining gaze shift in depth direction, light emitting diodes B and E, or D and C are lit at a plurality of positions with different distance in depth direction from the subject, and eye movement of the subject at that time is detected by an eye movement detecting portion. The signal of detection is processed in a signal processing circuit and is applied to a calculating portion. The calculating portion determines whether or not there is a disorder in gaze shift in depth direction of the subject by using any or all of latency in eye movement, time constant, amplitude, change in convergence angle, number of occurrence of saccade, and asymmetry of left and right eye movements, in response to the detected output of the eye movement.

Abstract: A target is presented on a board for calculation, eye movement of a subject while he is gazing at the target is detected by an eye movement detecting portion, the output of which is converted into a digital signal in a signal processing circuit and it is applied to a calculating portion. The calculating portion calculates small involuntary movement data in response to the input digital signal to find a value of a fractal dimension and time dependence of the fractal dimension to determine a disease related to brain function, and the output of determination is provided from an output portion such as a printer.

Abstract: When eye movement of a subject is detected by an eye movement detecting portion and head movement of the subject is detected by a head movement detecting portion, a line-of-sight calculating portion calculates the line-of-sight according to the detected outputs therefrom. A portion for generating an image to be presented generates an image as a task and presents the image to a task presenting portion. When a fixation point of the line-of-sight of the subject is determined by a fixation point determining portion, a mask image generated by a masking image generating portion is inserted to the task image by an image synthesizing portion, and it is presented at the task presenting portion. A portion for determining degree of advance of dementia determines degree of advance and possibility of Alzheimer's disease based on the particular movement of the line-of-sight of the subject at that time and on the percentage of correct answer to a prescribed task.

Abstract: In a medical diagnostic apparatus utilizing line-of-sight detection, targets are successively presented from different angles to the subject by a target presenting apparatus, eye movement of the subject while the subject is gazing at the target is detected by an eye movement detecting portion, the head movement of the subject is detected by a head movement detecting portion, and in response to the detection outputs, the spatial movement of the line-of-sight, rotation velocity component and translational velocity component of the head movement as well as the velocity component of the eye movement are calculated by a calculating portion, and the results are output to an output portion.

Abstract: In the medical diagnostic apparatus employing line-of-sight detection, eye movement and head movement of a subject are detected by eye movement detecting portion and head movement detecting portion, respectively, and images of the field of view of the subject are picked up by a TV camera. A calculating portion calculates a locus of the line-of-sight, a locus of the eye movement, the locus of the head movement, and vectors of spatial movement of the line-of-sight in response to the detected eye movement and the head movement. An image processing portion reduces the picked up image, a superimposer superimposes the images of the loci, the vector images and the images of the reduced field of view on each other, and the resulting images are displayed on a CRT display.

Abstract: Voice verfication of individuals is carried out by utilizing the peak value envelope of voice signals. The voice signal is separated into its positive and negative polarity portions and stepped peak value envelope waveforms are developed from each portion. The latter waveforms are quantized and normalized; the latter being carried out to provide waveforms having a total area therebelow which equals a predetermined area. The quantized, normalized envelopes are then compared with recorded envelopes which were previously calculated in the same manner as the former envelopes. Comparison is carried out by calculating the Hamming distance between the new and stored envelopes.

Abstract: A hologram memory apparatus in which the information is displayed as one-dimensional spatial pattern and recorded in a form of strip-shaped one-dimensional hologram having sharpness in counter proportion to the width of the light flux and the information is read by a one-dimensional photo detector array. The apparatus comprises an optical system for writing in the information having a common optical axis for the input information signal light and for the reference light. The apparatus can record either analog information or digital information by a single apparatus.
