Abstract: A stimulable phosphor sheet for radiation image recording and reproducing method is composed of at least two partitioned stimulable phosphor films laminated one or another [the partitioned stimulable phosphor film is composed of plural partitions that divide the stimulable phosphor film on a plane thereof to give plural stripe sections, and a stimulable phosphor layer placed in each stripe section] in such manner that the partitions of one stimulable phosphor film are arranged to cross the partitions of another stimulable phosphor film.

Abstract: A stimulable phosphor sheet for a radiation image recording and reproducing method comprising the steps of recording a radiation image as a latent image, irradiating the latent image with stimulating rays to release stimulated emission, and electrically processing the emission to reproduce the radiation image, is preferably composed of a stimulable phosphor-containing grid partition that contains a stimulable phosphor, a UV or visible light-emitting phosphor, or a reflective material and two-dimensionally divides the phosphor sheet on its plane to give plural small rectangular sections, and stimulable phosphor-incorporated areas which are rectangularly sectioned with the grid partition and which have a reflectance at the wavelength of the stimulating rays which differs from that of the grid partition.

Abstract: A stimulable phosphor sheet for a radiation image recording and reproducing method comprising the steps of recording a radiation image as a latent image, irradiating the latent image with stimulating rays to release stimulated emission, and electrically processing the emission to reproduce the radiation image, has partitions that divide the phosphor sheet on its plane to give plural sections, and stimulable phosphor-incorporated areas in the sections, wherein the phosphor-incorporated areas have a light-scattering length of 20 to 100 &mgr;m and a light-absorption length of 1,000 &mgr;m or longer, while the partitions have a light-scattering length of 0.05 to 20 &mgr;m and a light-absorption length of 1,000 &mgr;m or longer, under the condition that a ratio of the light-scattering length of the phosphor-incorporated areas to that of the partitions is 3.0 or more.

Abstract: A backing plate 1 for sputtering is constituted by a base portion 2 comprising a plate member made of aluminum or its alloy, a surface of which is attached with a target T of an ITO sintered body or the like and a cooling portion 3 in a flat plate shape having a cooling medium flow path 6 at an inner portion thereof. Further, the cooling portion 3 is integrally attached to a rear face of the base 2 by friction agitation bonding. The cooling portion 3 comprises a roll bond panel 4 made of aluminum or its alloy and inner hollow portions of bulged pipe portions 5 constitute the cooling medium flow path 6. Thereby, a backing plate which is light-weighted and has high cooling efficiency can be provided.

Abstract: An aluminum-copper clad member includes an aluminum-base member, a copper-base member and an insertion member made of pure aluminum or JIS A1xxx series aluminum alloy. The aluminum-base member and the copper-base member are clad via the insertion member. A heat sink includes a heat radiation portion made of aluminum-base material and provided with a plurality of tongue-like fins formed by skiving a surface layer of one side of the heat radiation portion and a thermal diffusion portion made of copper-base material and joined to the other side of the heat radiation portion via an insertion member made of pure aluminum or JIS A1xxx series aluminum alloy.

Abstract: A connected structure includes a supporting member and a bushing mounting member connected thereto. The supporting member is made of a pipe having a round cross-sectional shape. The bushing mounting member includes a bushing mounting portion for mounting a bushing having a rubber elastic member and a connecting portion protruded from the bushing mounting portion. The connecting portion is press-fitted into an opening at one end of the supporting member, and the connecting portion and the supporting member are joined together along a circumference of the supporting member by a friction agitation joining method. Accordingly, the connecting member which is light in weight and high in strength with an improved efficiency for utilizing the surrounding space and a predetermined characteristics of a bushing can be obtained.

Abstract: A friction agitation jointing method of workpieces for subjecting the workpieces made of metals having deformation resistance or melting points different from each other to friction agitation jointing in which two of the workpieces are subjected to the friction agitation jointing while forming a peak of friction agitation force or temperature on a side of the workpiece having a larger or a higher one of the deformation resistance or the melting points relative to a bond interface between the two workpieces.

Abstract: In a friction agitation joining method for joining metallic joining members, a joining device having a column-shaped rotor of a larger diameter and a pin-shaped probe of a smaller diameter integrally formed on an end of the rotor and protruded along an axis of the rotor is used for joining the metallic joining members. The probe is rotated and inserted into or around a butted portion of the joining members to soften a contact portion contacted by the probe by friction heat and to agitate the contact portion so that the joining members are butt joined. Each joining member has a thick portion at a butting side thereof The rotating rotor is contacted to the thick portions under pressure to soften the thick portions by friction heat so that a gap formed at the butted portion is filled with the materials of the softened thick portions.

Abstract: A novel flux is provided for use in the low-temperature brazing aluminum materials of varied compositions, the flux being composed of a KCl--NaCl--BaCl.sub.2 base and 0.5-5.0 wt. % of LiF and/or 1.0-10.0 wt. % of ZnCl.sub.2 added to the base. A method of flux brazing a low-melting aluminum material is also provided, and the method is carried out by applying such a novel flux as well as a low-melting brazing agent to the aluminum material portions to be adjoined. The brazing agent is composed of an Al--Si--Zn alloy which contains 3-12% by weight of Si and 15-70% by weight of Zn.
