摘要:
A device for performing identification by sensing the fingerprint of a finger includes an input unit. The input unit is constituted by a plurality of linear contact electrodes formed on a substrate, and a pressure-sensitive sheet formed on the linear contact electrodes and a resistance thereof changes in accordance with a pressure applied thereto. When the finger touches the surface of the pressure-sensitive sheet, a change in resistance is caused between the electrodes, and this change is converted to data of a one-dimensional electrical signal distribution. The obtained data is compared with registered data, thereby performing identification. The time required for signal processing necessary in the identification device can be decreased.

A storage and reconstruction apparatus for radiation image is comprised of a radiation image storage medium made of phosphor glass powder in which activators are formed according a radiation image. The radiation image storage medium emits a fluorescent light by irradiation of an excitation light, and the emitted fluorescent light is detected and converted into an electrical signal. The electrical signal is treated by an image processor and the radiation image is reconstructed.

A cell metamorphosing device includes micro dishes which serves as diaphragms and hold a mixed medium containing harmful cells and nano-scale particles, an AC voltage supply, a heater and an inductor. The AC voltage supply faces with the micro dishes 2 with a space, and applies a bias to the micro dishes 2, so that the nano-scale particles are bombarded onto the harmful cells and destroy them.

摘要:
In an acoustoelectric converter element, a light wave from a light source is introduced into a first optical waveguide of a vibration substrate, and diffracted by a diffraction grating disposed on the first optical waveguide. The diffracted light is directed to and detected by a photo detector. Here, the vibration substrate is so supported as to vibrate with respect to an acoustic wave. Therefore, the diffracted light detected by the photo detector is modulated by the acoustic wave, and a signal is output from the detector in accordance with the acoustic wave.

An opto-acoustoelectric device encompasses a diaphragm having a diffraction grating, the diaphragm is susceptible to a vibration driven by an external force; a light source oriented to irradiate the diffraction grating; and a photo detector configured to detect the light diffracted by the diffraction grating and to convert the detected light into an electric signal. The electric signal corresponds to a displacement of the vibration in the diaphragm.
