Title: Device for optical system
Inventor: MATSUURA MAKOTO
IPC: G11B7/09
Filed: 1983-05-09
Abstract: PURPOSE:To gauge the directivity of deviation of an optical axis due to the temperature change and prevent an unreversible deviation by providing an adhering means which sticks an optical assembly and a housing to each other and spanning this adhering means between both of them in one or several positions in a uniform spanning direction. CONSTITUTION:A position-adjusted optical assembly 14 is practically fixed with an adhesive 19 so that it is deviated approximately reversibly in accordance with the temperature change, and the adhesive 19 is so fixed that it is spanned between the optical assembly 14 and a housing 13 in the Y'-axis direction of an X'-Y' coordinate system in the figure where the center position to be adjusted between the optical assembly 14 and the housing 13 is the origin. In this adhering structure where the relative position relation between the optical assembly 14 and the housing 13 is determined by the spanning direction, it is clarified experimentally that the micro deviation of the optical assembly 14 appears remarkably in the Y'-axis direction in the figure and is restrained in the X'-axis direction; and that is, the deviation depends upon temperature characteristics in the same directions of the adhesive 19, and a deviated position (X', Y') of the X'-Y' coordinate system is restrained approximately to (0, Y'), and thus, the deviation is Y'- axis deviation.

Abstract: PURPOSE: To make economical, continuous filtration possible without interruption of the filtration due to washing of sand layer unlike conventional methods, by installing freely rotatable sludge-sucking slits and washing-water feeding slits above the upper surface of the sand layer of a cylindrical sand filter.  
     CONSTITUTION: In a cylindrical sand filter 1 for cleaning water are installed a double pipe 6 integrally rotating with a rotatable axis 2, suction slits 3 continuing through a suction conduit 6 to an ejector 10, an ejector 16, and a discharging slits 4 through a rotary joint 14 and the inner pipe 13 of the double pipe. While rotating, the sucking slits 3 delivers sludge to a sand washer 11 by the ejector 10. The discharging slits 4 discharge washed  sand through an inlet 17, the ejector 16 to recover the recess on the sand made by sucking sand. This method makes it possible to reduce washing water consumption for filtration layer to 1/3 that of conventional method, and to operate continuously without interruption.

IPC: F16B39/284
Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To prevent the locking of a nut over a long period by providing an eccentric screw block engageable with the screw of a bolt but off-centered to the shaft center of the nut body in the inner part of the nut. SOLUTION: The nut body 1 of a locking nut 10 has a locking part 1a on the top part, and an eccentric screw block 2 having a shaft center off-centered by δ to the shaft center L has a chamfer P of about 45 deg. on the bolt insert side end in order to avoid the interference with the bolt tip. The block 2 is inserted to the recessed part of the nut body 1 with the locking part 1a being laid in the state shown by the virtual line, and the locking part 1a is inclined. In the insertion of the block 2, a clearance α is formed in order to regulate the slippage of screw pitch between the nut body 1 and the block 2. When the locking nut 10 is fastened to a bolt 3, the force F orthogonal to the shaft center acts on the nut body 1, so that the nut 10 is not easily loosened.  Since the block 2 is integrally rotated with the nut body 1, the fastening can be performed at a regulated torque.
