Title: Non-destructive quantitative evaluation method for plasticity of steel product
Inventor: YAMAKAWA YUJI
IPC: G01N33/20
Filed: 1997-07-18
Abstract: PROBLEM TO BE SOLVED: To quantitatively evaluate the degree of residual distortion as plasticity by measuring a magnetic field of the surface of a steel product to determine a distribution range in terms of a difference between the maximum and the minimum values of a magnetic signal within a zone of a specified size. SOLUTION: A specified tensile load is applied to a test object 10 is applied to measure the degree of residual distortion with a π type displacement meter or the like. The surface magnetic field of the test object 10 after loaded is measured, for example, by a superconducting quantum interference device fluxmeter having a concentric type secondary differentiation detection coil and zoned by 5×5 cm<2> to define a difference between the maximum value and minimum value within the zone. A distribution range as a difference between the maximum and minimum values of a space differential value of each zone positioned on a specified line in the longitudinal direction of a narrow part 10b of the test object 10 correlates with the degree of residual distortion in a plastically deformed area. Therefore, for example, the surface of a steel material of the existing structure is scanned by the fluxmeter to extract a space differential value of each zone on a line along the direction of drawing the steel product. Thus, by learning the distribution range of the space differential values, the residual distortion can be obtained quantitatively.

Title: Method and apparatus for scraping sludge in settling basin
Inventor: SUZUKI KIYOSHI
IPC: B01D21/18
Filed: 1985-09-03
Abstract: PURPOSE:To provide an apparatus for easily detecting a position of an underwater carriage without arranging a detecting portion in a settling basin, by controlling a travel of the under water carriage by detecting the position of the carriage in the settling basin from the rotation of a rope-winding mechanism for towing the carriage. CONSTITUTION:By operating a rope-winding mechanism, an underwater carriage in a settling basin is travelled along a rail through a towing rope. A scraper attached to the carriage scrapes settled sludge. At the same time a shaft 26 is rotated through a sprocket 27. This results in the rotation of gears 32, 34. The rotation is transmitted to a shaft 33 to rotate a square thread bar 36. This results in the movement of a linear workset 39 along a shaft 40. When positions of limit switches 41, 42 are adjusted in advance so as to be set to the position in the settling basin and set to graduation of an indicating scale 46, the position of the carriage in the settling basin can easily be detected from the graduation of the indicating scale.

Title: Porous sheet of reinforcement type
Inventor: IIMURA MITSUO
IPC: B32B7/12
Filed: 1987-08-04
Abstract: PURPOSE:To heighten the ventilation and moisture permeability of a sheet by a method in which while a plurality of porous sheet with different melting points are laminated, many cracks are provided in the low melting point-porous sheet in said laminated sheet. CONSTITUTION:The filler such as calcium carbonate and an oxidation preventing agent, etc. are suitably compounded with the low melting point-resin providing adhesive property in heating, and they are formed into a sheet, and a low melting point-sheet is made. This sheet is uniaxially oriented or biaxially oriented at the temperature of at most the melting point of said resin, and the strain by which said resin acts as a nucleus near said filler is generated. Next, when said sheet is heat-treated at the temperature of at least the melting point of the resin, stress is generated at the position of said strain, and cracks occur. Consequently, the permeability or ventilation of gas or liquid is improved, since the filler acts as a nucleus and cracks occur near the filler in the low melting point-porous sheet which has been difficult to obtain sufficient porosity.

Title: Scroll type compressor
Inventor: IWANAMI SHIGEKI
IPC: F04C29/00
Filed: 1994-08-19
Abstract: PURPOSE: To prevent the excessive increase of pressing force between the scroll members of a scroll type compressor and to prevent the occurrence of abnormal wear, seizure, and breakage of a vortex type blade. CONSTITUTION: The drive key 10 of a driven crank mechanism 6 to intercouple a moving scroll member and a drive shaft (an expansion part 5a) is pivotally mounted on the end part of the drive shaft by means of a pin 10a. A compression reaction force F of fluid exerted on the center Cb of a bush to support the moving scroll member has a component FR of force in the direction of the drive key, which forms a force by which the moving scroll member is pressed against the fixed scroll member regardless of a centrifugal force exerted on an eccentric mass. Since the magnitude of the component FR of force is changed according to the magnitude of the inclination angle θof the drive key, the pivotally mounted drive key is energized in one way by a resilient body 12 and the inclination angle θ is reduced according to the increase of compression reaction force F. In this case, even in a case of liquid compression during starting wherein the compression reaction force F is abnormally increased, the pressing force can be suppressed to a proper value.
