摘要:
Materials having different compositions are arranged to prepare a molded form in which the sound velocity characteristic is varied from high frequency to low frequency from the center toward the periphery. An ultrasonic wave-radiating face of the molded form and the back face of the ultrasonic wave-radiating face are arranged in parallel to each other to prepare a transducer in which the center region can transmit/receive high-frequency ultrasonic waves and the periphery region can transmit/receive low-frequency ultrasonic waves.

A flexible shaft is inserted through a sheath constituting an insertion portion of an ultrasonic probe connected to an ultrasonic observation apparatus, an ultrasonic transducer driven to rotate, etc., is attached at the distal end portion thereof, and an ultrasonic wave can be transmitted and received through an acoustic window arranged around thereof. By using hydrocarbon-based oil having a kinematic viscosity of 20 mm2/s as an acoustic medium for filling the surrounding of the ultrasonic transducer in the acoustic window, ultrasonic attenuation at high frequencies can be reduced, decrease of the capacity of the acoustic medium due to volatilization can be reduced, and decrease of the capacity of the acoustic medium due to volatilization is reduced.

An ultrasonic transducer is provided at the distal end of a sheath included in an inserting portion of an ultrasonic probe for performing ultrasonic diagnosis. The ultrasonic transducer can transmit and receive ultrasound through an acoustic window 38 facing against the ultrasonic transducer through an acoustic medium filled around the ultrasonic transducer. At least the acoustic window is formed of a resin including a mixture of polyamide block and polyether ester block copolymer resin and polyurethane. Thus, multiple reflection, for example, can be reduced in the vicinity of the acoustic windows. Furthermore, the sheath portion may be formed of the same resin. Thus, the sheath portion can be inserted through an endoscope channel, for example, smoothly with less buckling.

A storage device having a plurality of recording devices in which a decrease in vibrations from the recording devices can be achieved with a small number of parts. A storage device having a plurality of recording devices mounted therein includes a handle for inserting and withdrawing the recording device into and out of the storage device. Two holding members each include a mounting portion where the recording device is mounted and a frame extending from the mounting portion to the handle. Two protrusions are formed to extend inwardly of a region surrounded by the recording device, the handle, and the two frames. A restriction plate is disposed so as to overlap the respective surfaces of the two protrusions; and a viscoelastic body is disposed at the overlapping portion for joining the two protrusions and the restriction plate to one another.

Disclosed is a game system which is capable of matching the replay range with the replay fee, even when the replay range is set to a portion of the played range. A game system allows a user to play the game in the predetermined range when an initial fee is collected from the user, and sets the play fee necessary for playing the game in the replay range according to the setting of the replay range. After the game is over in the predetermined range, the replay process is performed for allowing the user to play the game in the replay range, on the condition that the set play fee is collected from the user.
摘要:
A technique is proposed for reducing leakage electromagnetic field that reduces the electromagnetic leakage from a connection point between a communication coupler and a signal transmission apparatus and that can conduct both communication and transmission of electric power. The signal transmission apparatus includes: a first sheet conductive body portion constituting a lower portion electrode; and a second sheet conductive body portion in a mesh shape which is laminated on the first sheet conductive body portion while a gap area is sandwiched therebetween and which includes an uneven mesh size area on which a sheet impedance is continuously changed.

A radiation image capturing system includes a first image capturing apparatus incorporating a radiation detector for detecting a radiation which has passed through a subject and converting the radiation into radiation image information, a second image capturing apparatus incorporating a stimulable phosphor panel for detecting a radiation which has passed through a subject, converting the radiation into radiation image information, and holding the radiation image information, and a processor for controlling the first image capturing apparatus and the second image capturing apparatus according to image capturing instruction information. The processor includes a priority activator for activating the second image capturing apparatus in preference to the first image capturing apparatus when the processor is activated.
