摘要： A voltage and displacement sensitive probe with an electro-optic crystal, electrically conductive transparent films and adhered to a pair of parallel surfaces on the electro-optic crystal, a transparent elastic film which circumferential portion is bonded to the frame and which is symmetric with respect to any plane through the axis thereof, a probing needle bonded at its reflective bottom surface to the central portion on the film, a holder for holding the electro-optic crystal and the transparent elastic film via frame concentrically, a lead for grounding, and electrically conductive films for connecting between the films. Displacement detection of the probing needle is based upon the change in the length of the path of the light travelling through the electro-optic crystal being reflected by the surface and travelling in reverse direction. Voltage detection of the probing needle is based upon the phase difference between the two linearly-polarized light components.

摘要： A probing device includes a minute probe in which at least an end portion is formed by conductive material, a cantilever having one end to which the probe is attached, and another end fixed to a moving member movable relatively to a sample in each direction of X, Y and Z, a unit for moving the moving member relatively to the sample, a transducing unit for generating information of voltage or current by means of light, a connecting unit having a low electric resistance, for connecting the transducing unit and the end portion of the probe, a detecting unit for detecting a change in a physical amount occurring in the cantilever by a force caused between the probe and the sample by a relative proximity of the moving member to the sample, and a voltage measuring unit for measuring a voltage at a measurement point on the sample, which is determined based on an output of the detecting unit, by way of the transducing unit when the probe is contacted with the measurement point. By the constitution, it is possible to realize a voltage measurement with both an enhanced space resolution and an enhanced time resolution. Also, by using the probing device in an integrated circuit testing apparatus or system, it is possible to realize a stable probing to a minute wiring without increasing an electrical load with respect to the minute wiring and thus contribute to an improvement in the precision of a voltage measurement.

摘要： In the present invention, two ultrasonic receivers are provided in common for plural input planes, and the plural input planes are restricted to a plane not perpendicular to a line connecting the two ultrasonic receivers, so that the sufficiently practicable coordinate input device can be provided. When the line connecting two ultrasonic receivers is perpendicular to the input plane, the distances from the input device to the two ultrasonic receivers exist in plural sets, so that the coordinates of an input device cannot be specified. Furthermore, in order to acquire the coordinates of the input device by the two ultrasonic receivers, a positional relations between the two ultrasonic receivers and the input planes are made initial setting in advance. When set in advance, it is possible to acquire the position of the input devices in the plural input planes from the distance from input device to two ultrasonic receivers.

摘要： Disclosed is an authentication apparatus easily achieving convenience and high accuracy in authentication. The authentication apparatus has an authentication accuracy simulation section that simulates authentication accuracy and also has a registration information setting section that sets an ID and biometric information input as registration information. The authentication accuracy simulation section uses an ID and biometric information that has been input as registration information by a user at the time of registration and the registered registration information to simulate authentication accuracy with which the user is authenticated. When the authentication accuracy simulated by the authentication accuracy simulation section does not satisfy a predetermined condition, the registration information setting section rejects registration of the ID input as the registration information.
