Title: Manufacture of clad strip
Inventor: YOSHIDA TADATSUGU
IPC: B23K20/00
Filed: 1986-09-04
Abstract: PURPOSE:To pressure-weld a strip in the atmosphere and to continuously form a clad material by projecting a laser beam close to the apex of a strip approaching part by passing a dissimilar metal strip through rolls respectively, heating the trip surface rapidly and rolling it at the specific percentage reduction in thickness. CONSTITUTION:Dissimilar metal strips 1, 2 are overlapped at a roll bits inlet port 8, rolled by a rolling roll 5 and joined. A laser light 9 is projected on the metal strips 1, 2 of the roll bit inlet port 8 as a light flux Q. The light passing a point 10 repeats points 11-14 and the reflection, giving a strip energy at the reflection point. The energy giving is similarly performed on the other light in the light flux Q, the strip is rapidly heated and rolled immediately at the percentage reduction in thickness of more than 4%. The growth of the oxide film on the mating face of the strip is therefore restrained and a strong joining is obtainable.

Title: Recirculation pump installed in nuclear reactor
Inventor: OKADA AKIRA
IPC: G21C15/243
Filed: 1992-08-03
Abstract: PURPOSE:To keep resolutions even in case a pump loses its driving force and relieve the core stability and the transient characteristics by using a rolling bearing to a bearing means which supports a shaft in the thrust direction. CONSTITUTION:A rolling bearing A consisting of rolling elements 24, inner and outer rings 25, 26, and a retainer 27 is furnished on the undersurface of a thrust disc 20 at the bottom of a shaft 10. The inner ring 25 rotates together with the disc 20, while the outer ring 26 fixed to the upper part of a motor cover 8 is at a standstill even while a pump is in opeeation. A raceway 28, 28 where the rolling elements 24 are in contact is formed in the circumferential direction on the mating surface of each ring 25, 26, and the rolling elements 24 are held by the retainer 27 on the outer ring 26 so that they can rotate freely while their positions remain unchanged. Thereby the thrust force applied to the shaft 10 is received by the bearing A, so that the rotational resistance is reduced to a great extent, and revolutions of the pump are kept with the voluntary circulation force as the drive motive. Accordingly the flow resistance of the impeller part is reduced to lead to enhancement of the rate of flow in natural circulation, which permits relieving of the core safety and transient characteristics when the pump loses its driving force.

Title: Structure using net material, sheet and end part treating of net material
Inventor: YAMADA TOSHIHIKO
IPC: A47C23/28
Filed: 1999-07-21
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of a local overstrain in a net material and raise the reliability of the net material. SOLUTION: This net material 10 is obtained by treating each end part 15 of a net material having a three-dimensional structure by a thermal fusing means such as vibrating fusion so that the end part 15 is hardened without cushioning properties as compared with those of a site located on the inside of the end part 15. Thereby, when an end part engaging member 20 as an engageable member is installed in a frame 30 constituting the structure so that an inserting port 21a of an inserting gap 21 faces in a specific direction, the engagement can be carried out simply by inserting the end part 15 into the inserting gap 21. All the site of the end part 15 is inserted into the inserting gap 21 and a force is applied to an engaging piece 23 on a face without a specific spotlike site when a load is applied.  As a result, the damage to the net material 10 caused by an excessive force applied to a specific site can be prevented as opposed to a conventional method.
