摘要： An identification apparatus that keeps the conditions for imaging uniform among successive identifications and requires a user to perform only a series of simple maneuvers. An identification apparatus comprising a guide member, a light source, and an imaging unit. The guide member includes a pattern or a structure that inspires a user to position his/her finger thereon or to approach his/her specific finger region thereto. A contact member such as a button switch is preferably located at a position in the guide member at which a fingertip is to be positioned. An optical opening is formed at a position coincident with a position at which a portion of a finger to be imaged for identification should be placed. The light source radiates near-infrared light through the portion of the finger to be imaged. The imaging means acquires an image of the finger, and the apparatus compares the image to previously registered images. The apparatus may also include dual light sources power saving functionality, and means for limiting the interference of external light sources.

摘要： An MRI system using an open type magnet, wherein two coils different in radius for generating gradient magnetic fields in a vertical direction are arranged in the open type magnet for generating a static magnetic field in the vertical direction. Currents are caused to flow through the two coils in directions opposite to each other to improve the degree of uniformity of the magnetic field in the vertical direction, thereby reducing the degradation thereof by equal to or smaller than 2 figures compared with the degree of uniformity of the static magnetic field generated by the existing MRI system. The positional information about a read-out direction is given through the dynamic control for the RF magnetic field to give the positional information about other two axes directions based on the gradient magnetic field having strength much larger than that of nonuniformity of the magnetic field.

摘要： The present invention aims to stabilize sound-electricity conversion characteristics of a diaphragm-type sound-electricity conversion device as well as to decrease the noise level of an ultrasonic diagnostic apparatus using the sound-electricity conversion device. The sound-electricity conversion device is configured by a capacitor cell including a lower electrode formed on a silicon substrate and an upper electrode over the lower electrode, the lower and upper electrodes sandwiching a cavity. An electrode short-circuit prevention film is formed on the upper electrode on the cavity side. The electrode short-circuit prevention film is formed of a material with an electrical time constant shorter than 1 second and longer than 10 microseconds, such as silicon nitride containing a stoichiometrically excessive amount of silicon. As a result, the electrode short-circuit prevention film has small electric conductivity, and thus it is made possible to prevent the film from being charged with electric charge and to avoid the drift of the electric charge. Consequently, the sound-electricity conversion characteristics of the sound-electricity conversion device stabilize, and further the sound noise level of the ultrasonic diagnostic apparatus decreases.

摘要： A nuclear-magnetic-resonance inspection apparatus that enables an examiner to designate directly a section of a subject to be imaged. The NMR inspection apparatus has a section-designating unit containing reference objects A, B, and C that can be set at three reference points, and can be held in the hand of an examiner to be moved and operated in close proximity to the subject, wherein a prescribed part of a plane including the reference objects set at up to three reference points is the section of the subject to be imaged. While watching the subject, the examiner can directly designate a section to be imaged. Thus, diagnoses can be made easily and quickly.

摘要： This invention provides a technology that freely changes the frequency of a reference signal in a digital ultrasonic diagnosis device and makes it possible to conduct various high-quality or high-speed imaging. Reception signals obtained by an ultrasonic element group disposed in an array are digitized in a sampling cycle higher than a Nyquist frequency of the reception signals, and are mixed with reference signal. The mixed signals are then accumulated in a sampling direction, a number of the mixed signals accumulated being equal to a number of a plurality of samples, and are delayed and added by wave reception focusing means. The reference signal serially read out and used from memory means in such a manner as to correspond to the sampling number of the reception signals. A reference signal train acquired from signals, the frequency of which decreases gradually with a lapse of time, from wave transmission, or a reference signal train obtained alternately from two signals having different frequencies, may be stored in advance in memory means.

摘要： A sensitizer for tumor treatment has a structure such that a lipophilic group and a hydrophilic group are bound to one and the same carbon atom in a compound containing a xanthene dye structure. It is important that the lipophilic group and hydrophilic group are bound to one and the same carbon atom; if they are separated from each other, no sufficient effect is obtained. Thus, the sensitizer possesses both lipophilicity and hydrophilicity. This sensitizer has a function of promoting acoustic cavitation and a function of revealing an antitumor effect and is an agent highly accumulable in tumor tissues. Thus, this sensitizer is highly selective for tumor tissues and enables the treatment of malignant tumor using ultrasound.

摘要： By providing an ultrasonic irradiation apparatus for generating acoustic cavitation efficiently, it is intended to realize an ultrasonic therapeutic apparatus for generating the action of cavitation on a living body suitable for medical treatment of malignant tumors and medical treatment of thrombi and calculi, an ultrasonic diagnostic apparatus for generating cavitation for emphasizing an ultrasonic echo image such as a blood flow and utilizing the reflection capability of the cavitation, an ultrasonic chemical reaction accelerating apparatus, an ultrasonic cleaning apparatus or an ultrasonic sterilizing apparatus. Irradiation focus/code signals for defining irradiated acoustic fields of a fundamental wave and a second harmonic wave as well as focus positions/acoustic pressure distribution forms of the respective waves are applied from an irradiation unit main control circuit to drive phase generating circuits. Generated drive phases are applied to drive signal generating circuits, generated drive signals are applied to element drive circuits and a group of fundamental frequency elements and a group of second harmonic elements are driven. The drive phases are controlled such that the fundamental wave and second harmonic wave are superimposed on each other in a medium near a focal point, thus generating acoustic caviation locally and efficiently.
