Filed: 1989-01-14
Abstract: PURPOSE:To make a feeder high in stiffness, and its linear movement extensive as well as to enable its feeding to be smoothly carried out with high accuracy by providing a cone scroll, followers and a slider for the feeder which transforms rotating movement into linear movement in various machine tools. CONSTITUTION:The feeder consists of a cone scroll 1 provided above a direct drive motor 6, a spiral thread ridge 11 provided on the conical surface of said scroll, and a slider 3 which is guided by two sets of followers 2 engaged with said thread ridge 11 in such a way as to be linearly moved. The rotation of the motor 6 therefore permits the cone scroll 1 to be rotated and roller followers 21, 22, 23 and 24 and the slider 3 supporting these followers are moved while being pushed by the ridge 11. when the motor 6 is rotated by one turn in such a way that the slider 3 is moved to the left, the roller followers 23 and 24 are moved to a position where the roller followers 21, 22 have been in existence. On the contrary, when the motor 6 is reversely rotated by one turn in such a way that the slider 3 is moved to the right, the roller followers 21 and 22 are moved.

IPC: G01S13/90
Filed: 1980-01-25
Abstract: PURPOSE:To correct distortions over the entire part of swaths by inserting a lens which corrects the inclination of a reconstructed image in its range direction and a lens which parallel moves the reconstructed image to the front face of a data film recorded with holograms. CONSTITUTION:A lens 31 which changes the advance direction of light by range lengths is inserted to the front face of a data film in which holograms are stored. The lens 31 allows the light incident to the shortest range of swath width to advance straightforward like the solid line (i) and with an increase in the range length, it changes the advance direction of the light like the dotted line (j) and changes the light incident to the longest range like the solid line (k). When a target has a speed, the position of its virtural image is created linearly unless the lens 31 is inserted but if the lens 31 is inserted, the virtual images of all the ranges such as (m), (n) are moved to the position (l) of the virtual image of the shortest range point, thus at the same azimuth point, the advance direction is made the same as the shortest range point despite change in the range length.

Abstract: PURPOSE: To achieve the perfect separation of water and solids by suction-filtering material in a treating tank with a tubular filter, discharging the remained treating material to the outside of the tank with a screw conveyor and sucking the residual water leaching out from the discharge route into the tubular filter.  
     CONSTITUTION: When the treating material such as sludge is pressure-fed into a treating tank 2 through lead-in port 14, the fine granular solids and water leaches into a tubular filter 23 through its water feed port 24 of the filter 23 and the treating material leaches in that state into the filter 23 from the open bottom surface of the filter 23. Next, when the revolving speed of the revolving shaft 29 increases, the solids in the filter 23 are flown toward the inside wall surface by centrifugal force and drop into the tank 2 and remain there. The water content in the filter 23 is sucked through suction hole 28 into suction barrel 25 and is discharged through a discharge pipe 19 and discharge housing 15. On the other hand, the revolution of a screw 7 causes the treating material in the bottom of the tank 2 to be conveyed upward in a conveying barrel 3, where it is compressed and the squeezed out water content passes through the water feed port 24 through the through-hole 6 and is fed into the filter 23.
