Abstract:
Actuators employable for oscillating movement of a load. An improved actuator may include at least a first shape memory member that is actuatable to affect at least a portion of the oscillating movement of the load. The actuator may further include a second shape memory member actuatable to affect at least a second portion of the oscillating movement of the load. The utilization of one or more shape memory members facilitates the realization of controllable and reliable oscillating movement of a load in a compact manner. Such actuators may be used in imaging catheters having an ultrasound transducer disposed for oscillating movement to scan across an internal region of interest. Such imaging catheters may be used in generating three dimensional and/or real-time three dimensional (4D) images.

PROBLEM TO BE SOLVED: To provide a sounder casing structure capable of preventing sounder rupture or function damage caused by water deposition.SOLUTION: In a sounder casing structure comprising a base 2 including a partition wall 6 for partitioning into a first space 16 and a second space 17, a case 4 defining a side of the first space 16 in the base 2, and a cover 3 defining a side of the second space 17 in the base 2, a frame body 7 is provided on the partition wall 6 for fixing an outer peripheral part of a sounder 5 so as to protrude from a sounding plane of the sounder 5 to a side of the second space 17 on the partition wall 6, a shield wall 8 is provided via a groove 9 outside of an outer peripheral surface of the frame body 7 and a shield plate 10 is provided, inside of the shield wall 8, at a position where a void is generated between the frame body 7 and the shield wall 8.
Abstract:
A distance sensor for vehicles is provided which includes a sensor device and an electric connector for an electrical connection between the sensor device and a mating connector. The connector includes at least one first terminal pin and at least one second terminal pin. The first terminal pin has a first section leading to the sensor device and a second section extending toward an inlet opening of the connector. The second terminal pin has a first section leading to the sensor device and at least two branched second sections extending toward the inlet opening of the connector. Specifically, the second terminal pin is shaped to provide two-pin plugs, thereby permitting the size of the connector to be reduced, which facilitates ease of installation of the distance sensor to, for example, a bumper of the automotive vehicle.
Abstract:
The present invention relates to an ultrasound therapy system using high-intensity focused ultrasound. The ultrasound therapy improves ultrasound and heat release characteristics and provides an ultrasound probe which easily performs manufacturing and maintenance processes. According to the present invention, a housing is recessed on the inward side around the upper-part edge. A plurality of mounting holes is uniformly formed from the outside at a constant radius to the edge in the center of the upper part. A plurality of probe units is respectively installed in the plurality of mounting holes to form a sphere on the upper part of the housing. And a grounding film covers the sphere which the plurality of probe units forms. At this point, the probe unit has a structure that a first connection pin is protruded to the lower part of the housing in the lower part of a copper connection bar and a rear block, a piezoelectric wafer, and an acoustic matching layer are sequentially stacked on the upper part of the connection bar. The upper surface of the probe units installed on the housing, the acoustic matching layer, forms the sphere. The grounding film is formed on the acoustic matching layer. A cover layer can be formed on the grounding film.

PROBLEM TO BE SOLVED: To provide a distance sensor for a vehicle which can be easily attached to a mounting hole of a bumper.SOLUTION: A sensor body 41 held in a cushion body 42 is fitted to a bezel 49 and a base 51 of a retainer 54 is fitted to a retainer fixing piece 59 of the bezel 49. Four arms 52 are extended from the base 51 of the retainer 54 in the axial direction thereof and a pawl 53 being V-shaped as viewed in the axial direction and triangular as viewed in the direction perpendicular to the axis is formed at the tip of each arm 52. When an ultrasonic sensor 3 is inserted into each of the mounting holes 47 of the bumpers 2 and 4, the pawls 53 of the retainer 54 are made to be engaged with inner peripheral edges 47a of the mounting holes 47.
