IPC: G03D15/10
Filed: 1999-07-09
Abstract: PROBLEM TO BE SOLVED: To dispense with the frequent cleaning of the surfaces of a driving roller and a follower roller by a worker and to prevent the meandering of a body to be conveyed by subjecting the surface of at least the driving roller to high friction treatment. SOLUTION: The peripheral part of a driving roller 3b contains SiC particles as hard particles 3d having 20-100 μm diameter in a matrix 3c comprising chloroprene rubber. When a negative sheet is conveyed while holding between the driving roller 3b and a follower roller 3a as a pair of conveying rollers 3, the SiC particles 3d bite moderately into the surface of the negative sheet to attain a high coefficient of friction and the negative sheet is reliably conveyed without causing slip. High friction treatment is preferably carried out at a relatively low cost by the coating of the surface of a metallic roller with a high friction layer or the roughening of the surface of a metallic roller besides the embedding of hard particles into a rubber roller.

Title: Ball mill
Inventor: GEERUHARUTO BIYUURERU
IPC: B02C17/16
Filed: 1985-09-06
Abstract: A drive body (4) which is rotationally driven via a shaft (6) projects into a fixed housing (1) closed by a cover (2). The annular-gap-shaped grinding chamber (M) formed between the housing (1) and the drive body (4) is partially filled with grinding balls, for example to 75%, and grinding stock flows continuously through it. The grinding stock enters from a product inlet (8) via the inlet gap (7) into the grinding chamber and leaves the latter through the discharge gap (3) which does not let through the grinding balls. The grinding chamber (M) is continuously widened from the mouth of the inlet gap (7) up to a deflection point (U). This results in a better starting behavior and a substantially more effective grinding, because a considerably higher grinding ball filling ratio can be achieved at the same circulating time of the grinding balls.

Title: Pile foundation structure
Inventor: KOBAYASHI HARUO
IPC: E02D27/12
Filed: 1999-07-12
Abstract: PROBLEM TO BE SOLVED: To surely exhibit high aseismic property at low cost even in the case of construction in the ground having a bad condition such as a liquefaction layer by providing an underground continuous wall forming the plane of structure connected to piles adjacent to each other. SOLUTION: A wall plate-like soil cement solidified wall (SMW) 4 is formed as an underground continuous wall in plane arrangement such that the plane of structure formed by adjacent piles 2 is actualized. The interface part between the SMW wall 4 and the pile 2 is formed by a little separation arrangement, addition of an auxiliary wall to the earthquake horizontal force vertical to the plane of structure, or connection between the heads. The SMW wall 4 is arranged in an upper layer 3b where a liquefaction layer of the ground exists. When an earthquake occurs, the inertia force of a building 1 and the forced deforming force of the upper layer 3b are applied to the piles 2, but the horizontal force is remarkably reduced by the frictional force between the side of the SMW wall 4 and the upper layer 3b so that excessive stress is not generated.  Thus, even in the case of construction in the ground 3 having a bad condition, high earthquake proof can be surely exhibited at low cost.
