Abstract: [Problems] Provision of a system for assisting diagnosis/treatment of stroke which can easily provide supportive information so that the type of stroke can be determined appropriately and corresponding treatment strategy can be implemented. [Solutions] When the device for assisting diagnosis/treatment of stroke 101 acquires information of CT images, DWI, ADCmap, and MRA images indicating state of stroke from the device for providing information about state of stroke 103, it uses the acquired information of images and the information about laboratory findings to determine the type of stroke in a unit of stroke type determiner trained to use the predetermined information of images and the predetermined information about laboratory findings to determine the type of stroke corresponding thereto.

Abstract: There is provided an IC socket having a plurality of contact pins 1. The plural contact pins 1 are arranged in a matrix form so that the pitch thereof at one end agrees with the electrode pitch of a semiconductor device 13 to be mounted and the pitch at the other end agrees with the pitch of the electrical connection terminals of an external connection body to be connected.

Abstract: A method of manufacturing an optical module package, which comprises the steps of, attaching a first member to a frame by means of silver-brazing to obtain a frame structure, applying an Au plating to the frame structure applied with the silver-brazing, and soldering a second member to the frame structure applied with the Au plating, wherein the method further comprises the steps of subjecting the frame structure to a high temperature dehydrogenation treatment of heating the frame structure in an non-oxidizing atmosphere at a temperature of 340.degree. C. or more for 10 minutes or more after the silver-brazing step and before the Au plating step, and subjecting the frame structure to a low temperature dehydrogenation treatment of heating the frame structure in an non-oxidizing atmosphere at a temperature ranging from 240.degree. C. to 260.degree. C. for 5 minutes or more after the soldering step.

Abstract: A package for optical semiconductor device comprising a metallic frame having a side wall provided with an optical fiber-securing portion for securing an optical fiber to be introduced through the side wall, and a metallic bottom plate for mounting the optical semiconductor device thereon. The metallic frame is provided at a lower portion of the side wall thereof with securing parts for securing the package to a substrate, each securing part outwardly extending in a direction parallel with the metallic bottom plate. The level of bottom face of the metallic bottom plate is made lower than that of the bottom face of the securing parts. The securing parts are integrally formed with the metallic frame.
