Title: Decreasing method for residual stress
Inventor: MATSUMOTO TAKERU
IPC: B23K31/00
Filed: 1981-07-31
Abstract: PURPOSE:To improve tensile residual stress in the inside surface of the pipe of a welded joint relatively easily to a decreased or compressed state by chipping the outside surface of the pipe in the welded joint part of pipes down to a constant depth then subjecting the joint part to build-up welding while cooling the inside surface of the pipe to restore the same state as the original shape of reinforcement of weld. CONSTITUTION:The outside surface of the weld zone 2 of a joint to be improved of the residual stresses in the inside surface of an existing or newly constructed pipe 1 is chipped down to a constant depth by a mechanical means such as a grinder. While the inside surface of the pipe 1 is cooled with tapping water, static water or the like, the weld zone is subjected to build-up welding 3 to restore the original shape. The thermal stresses shown by a solid line curve 2 are generated by the temp. difference, shown in the graph, generated during execution of the welding 3, and tensile plastic deformation arises in the inside surface and compressive plastic deformation in the outside surface respectively. When a uniform temp. distribution is attained by cooling after the welding 3, the stress state shown by a broken line curve beta is obtained, wherein the inside surface has compression and the outside surface tension. As a result, the parts near the welded joint have higher resistance to stress corrosion cracking and cor rosion fatigue.

Abstract: PURPOSE:To reduce the occupying area of a light detector and to enhance resolving power, by laminating semipermeable light detectors to allow the same to operate as (N) light detectors having different spectral sensitivities. CONSTITUTION:P-type layers 2, 6, 11, I-type layers 3, 7, 12 and N-type layer 4, 8, 13 comprising amorphous silicon hydride are successively laminated onto transparent conductive films 5, 9, 10 as individual semipermeable light detectors and, further, a PIN-type photoelectric converter element formed by applying a transparent conductive film 14 to a N-type a-Si : H layer is used. The transparent conductive film achieves function as a signal take-out port common to both of upper and lower PIN-type photoelectric converter elements holding said film therebetween. A plurality of thus formed PIN-type photoelectric converter elements are laminated onto a plurality of stainless steel substrates 15 and the shortcircuit photocurrent generated in each PIN-type photoelectric converter element or the photocurrent at the time when a definite inverse bias has been applied is detected as an output signal. Then, the signal generated in each light detector by the incidence of light to be measured is subjected to reverse converting processing by using an N-order square matrix having regularity to calculate the spectral distribution of light to be measured.

Abstract: PURPOSE: To project the optical flux upon an object without any reduction in the light flux of a finder optical system by arranging a focus image hologram at a preset position of the finder optical system to project the illunating light backward from a light source.  
     CONSTITUTION: A focus image hologram 8 of a vertical type phase diffraction element is arranged in a position, where an intermediate image is formed by the focusing lens 7 of a finder optical system.
