Title: Detector for inclination of plane
Inventor: BABA TAKAO
IPC: G01B11/26
Filed: 1983-05-04
Abstract: PURPOSE:To detect the inclination of an objective plane highly precisely without any influence of surface reflection characteristics of the objective plane by radiating light images of slits which cross each other at right angles, and extracting a couple of light images from the output signal of a two-dimensional image pickup element. CONSTITUTION:The two-dimensional image pickup element 10 has an axis of photodetection crossing perpendicularly the axis of projection of a light source 9a which converts a converged light beam into a slit-shaped light image and radiates it, and a light source 9b radiates the light image of slits crossing each other at right angles at an intersection. A means 15 judges the two-dimensional inclination of the plane of the body 13 to be detected from position information on the detected slit couple obtained through a means 14 which extracts the light image couple from the output signal of the element 10, and the element 10. Therefore, the angle of inclination of the objective plate is detected precisely without any influence of the reflection characteristics of the plane of the object 13.

Title: Picture reader
Inventor: MUROKI KENICHI
IPC: H04N1/00
Filed: 1992-02-28
Abstract: PURPOSE:To always read a film picture of various sizes sharply at all times by inhibiting focus control when a film with a size having a deep field depth is detected. CONSTITUTION:When a file is set to a carrier 700 prepared corresponding to films of each size while a picture region of the film is in matching with a carrier window 710, the carrier is set to a truck of the main body. When the carrier 700 is set to the truck, the optical path of a carrier presence sensing transmission type photo sensor fixed in the trunk is interrupted and its output inverts from a low level (0) to a high level (1). Thus, the setting of the carrier 700 is detected, when a film whose field depth is deep (in this case 4X5 inch size) is set, focus control (automatic focus control) is inhibited.

Title: Rolling mill for round bar, wire
Inventor: SUZUKI SHIGENOBU
IPC: B21B1/16
Filed: 1993-03-12
Abstract: PURPOSE:To remove spreading, to improve the accuracy of a section and to extend an area of size-free rolling by making calibers of a 4-stage-rolling mill oval, round or oval near round, round and round in order. CONSTITUTION:When a material 1 is rolled by an oval caliber of a 2-roll miss Sn-2 at a 1st stage and then, the material 1 is rolled by a round caliber of a 2-roll miss at a 2nd stage from the orthgonal direction, the reduction rate of area is increased, therefore, the spreading rate, also, becomes large, however, the rolling by a round caliber of a 2-roll miss Sn at a 3rd stage is performed after the reduction of area is performed once and from the direction with 2-roll mill Sn-2 at a 1st stage, therefore, the reduction rate of area is almost several % or less. As a result, the spreading hardly occurs in this stage. Consequently, the effect of the spreading is less and a bar having nearly complete roundness can be obtd. Further, since a 4-roll mill Sn+1 is equipped at the final stage, many sizes of round bars can be rolled by one kind of caliber roll.

IPC: B01D35/06
Filed: 1989-03-30
Abstract: PURPOSE:To remarkably improve dehydration efficiency and energy saving by mixing a dehydration promoter, which has a foaming function, with a slurry, by dehydrating the slurry electro-osmotically and then by carrying out a mechanical dehydration. CONSTITUTION:A dehydration promoter, which has a foaming function (e.g. Al power), is charged from an input vessel 12 into a slurry in the first treating tank 1 and they are mixed together by a stirrer 14. Then, the slurry is made to flow into the second treating tank, and a pressing plate 23 is allowed to descend by its dead weight. A specified voltage is applied between a couple of electrodes 21a and 21b, which are arranged at a lower face of the pressing plate 23 and below a filter 22 respectively, so as to separate water from the slurry particles owing to an electroosmotic action, and the separated water is discharged through a drain 25. Next, the pressing plate 23 is pushed down by driving an actuator 24 so that the water remaining in the slurry is squeezed and discharged out of the filter 22. It is possible, as a result, to dehydrate a slurry containing much water such as sludge and industrial waste efficiently.
