An IC socket for receiving an IC package having a plurality of electrical contacts on a bottom face thereof is disclosed. The IC socket has an insulating housing that receives the IC package and a plurality of elastic contacts, one end each being secured to the insulating housing, and a remaining end of each contacting at least one of the electrical contacts on the bottom face of the IC package. The IC socket also has a spring member carried by the insulating housing that determines an accepting position for the IC package being accepted into the insulating housing, and that restrains an amount of horizontal movement of the IC package caused by bending of the elastic contacts as the IC package is pressed down.

A transmitter/receiver transmits and receives ultrasonic waves to and from a desired region of a subject via an ultrasonic probe. A signal processor obtains a plurality of physical quantities from signals outputted by the transmitter/receiver having received ultrasonic echoes from the subject. A voxel-value generator generates a voxel value containing the plurality of physical quantities. An image generator generates a three-dimensional image by using the plurality of physical quantities including any of the rate, power value or dispersion of a blood flow contained in the voxel value and sequentially executing a rendering process on each voxel. A display controller controls a display to display the generated three-dimensional image.

The IC socket assembly includes the heat sink for abutting the upper surface of an IC package to dissipate heat generated thereby, and a fixing member for fixing the heat sink to the housing. The fixing member includes: a frame, mounted on a surface of the circuit board, on which the housing is mounted; a back plate, mounted on the opposite surface of the circuit board, having engaging arms, which are inserted through apertures of the circuit board and engage the frame; a pair of loading beams, fixed to the engaging arms; and a pair of levers, axially supported by the loading beams, for urging the heat sink toward the housing.
摘要:
An IC socket assembly includes an IC socket, constituted by: a plurality of electrical contacts; an IC package mounting surface; an insulative socket housing for holding the plurality of electrical contacts at the IC package mounting surface; and an urging member for urging an IC package, which is mounted on the IC package mounting surface, toward the plurality of electrical contacts so as to establish electrical connections therewith; and the IC package. The IC package has a frame member provided about the periphery of a main body thereof.

An ultrasonic probe includes a plurality of transducers arranged in XY directions, a plurality of backing members stacked along the X or Y direction, in back of the transducers, and a plurality of heat conductive sheets sandwiched between the plurality of backing members and higher in heat conductivity than the backing members.
摘要:
An integrated circuit socket comprises an insulative housing having an integrated circuit package receiving recess provided with a plurality of contact receiving openings arranged in a matrix. Contacts are arranged in the contact receiving openings. Each of the contacts has a base fixed to the contact receiving opening and a contact arm that extends away from the base. The contact arm has a contact portion with a contact point at an uppermost end. The contact portion overlaps with the contact arm of an adjacent one of the contacts. First partition walls separate the contact receiving openings in a direction substantially perpendicular to a direction in which the contact arms extend. The uppermost ends are arranged below tops of the first partition walls.
摘要:
The present invention provides an electrical connector with a plurality of contacts therein and a conductive shutter rotatable between a closed position covering the plurality of contacts and an open position exposing the plurality of contacts. A shield member encircles the plurality of contacts and is configured to make electrical contact with the conductive shutter when the conductive shutter is in the closed position. A mating connector and a connector arrangement are also provided.
摘要:
Deformation of a socket housing during connection of an IC package is prevented, and reliable electrical connections are secured in an IC socket assembly. The IC socket assembly is constituted by a plurality of electrical contacts; an insulative socket housing for holding the electrical contacts arranged in a matrix; a reinforcing plate having an opening at its center, through which the electrical contacts are exposed, for supporting the lower portion of the socket housing; a cover member, which is rotatably supported by the reinforcing plate, for cooperating with the reinforcing plate to sandwich and hold the IC package therebetween and to press the IC package against the electrical contacts; and reinforcing beams, which are supported by the reinforcing plate and provided across opposing edges of the opening, for supporting the socket housing.
