Title: Initial fatigue damage evaluating method for heat-resisting low alloy steel
Inventor: FUJII TOSHIYUKI
IPC: G01M99/00
Filed: 1995-06-19
Abstract: PURPOSE: To be able to valuate the initial fatigue damage of a heat-resisting low alloy steel from the change of an inner structure even at the stage of the initial fatigue before a microscopic crack occurs on the surface by conducting the steps of gathering a sample, obtaining the ratio of different structures, and comparing the different structures. CONSTITUTION: The ratio of the dipolar wall structure of an inner structure to the subgrain structure is obtained from the sample gathered from a real machine. The chart of the ratio of the dipolar structure to the subgrain structure of the inner structure in the known distortion amplitude and known life consumption of the same composition materials are previously obtained. The initial fatigue damage before the microscopic crack occurs and the life consumption can be estimated by comparing the chart with the value obtained from the real machine. Thus, the initial fatigue damage of the case of the heat-resisting low alloy steel such as a steel material for a boiler can be evaluated.

IPC: B65G65/48
Filed: 1985-08-12
Abstract: PURPOSE:To simplify the whole device while facilitate the maintenance and inspection of a plow driving part by providing a plow driving device utilizing a vacant space inside a conical cone. CONSTITUTION:When a plow driving disk 11 is moved in the direction of A by means of a motor 10 to start discharging, stores 6 are discharged by a plow 12 and falls down to a delivery port 3. In this case, the plow 12 is opened being subjected to a force in the direction B due to the resistance of the stores. Since the root part of the plow 12 is engaged with a shaft 24 via a spacer 23, however, the opening of the plow 12 is restricted by the height of the spacer 23. Therefore, even through the motor 10 rotates at a constant speed,the quantity of delivery of a silo can be controlled by adjusting the delivering radius of the plow 12. When the motor 10 is reversed rotating the plow driving disk in the opposite direction, the plow 12 is rotated in the opposite direction due to the resistance of the stores and drawn toward the blow driving disk 11. When the plow 12 is placed in this position, the spacer 23 can be easily replaced.

IPC: B29C67/00
Filed: 1996-07-05
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of deformation such as warpage in an obtained shaped article by repeating such a process that a resin layer formed by cooling a photosensitive resin to coagulate the same is irradiated with radiation (hereinbelow merely said to be light) such as ultraviolet laser to form a cured resin layer. SOLUTION: A photosensitive resin is supplied into a resin housing tank T in the amt. corresponding to one resin layer by a resin supply means and the (n+1)-th resin layer p(n+1) composed of a liquid photosensitive resin is formed on the surfaces of the n-th resin layer pn and a cured resin layer hn. The (n+1)-th resin layer p(n+1) is cooled to its coagulation point or lower to coagulate the photosensitive resin constituting the resin layer p(n+1). The surface of the (n+1)-th resin layer p(n+1) is selectively irradiated with light by a light irradiation means to form the (n+1)-th cured resin layer h(n+1). Since the (n+1)-th cured resin layer h(n+1) is certainly supported by the solid layer consisting of the coagulated resin layer (pn) and the cured resin layer (hn), deformation such as warpage is not generated at an overhang part.
