Abstract: 183,107. Beck, W. July 11, 1921, [Convention date]. Addition to 172.292. Balancing moving parts; casings.-A centrifugal pump or blower of the kind referred to in the parent Specification has a ring m on the shaft to make a tight joint between the shaft and the casing when the pump is at rest. In the form shown in Fig. 1, the ring has a flange n and can move axially on the pump shaft d under the influence of the difference of pressure between the interior and exterior of the pump casing to make tight engagement with the annular surface o on the casing. In a modification, the ring is operated by a centrifugal device acting against adjustable springs. In another modification shown in Fig. 3, a ring m<2> in the form of a conical valve is secured to the shaft d<2> and is held by a spring v secured to the shaft d<2> and is held by a spring v in engagement with a conical seat p<2>. When the pump is in action the weighted rockers w compress the spring to unseat the ring m<2>. The difference, of pressure on opposite sides of the rotor, owing to the different sectional areas of the chambers II, III, may also be utilized to operate. the ring.

Title: Analytical method and device of substrate incident negative ion in etching plasma
Inventor: HAYASHI TOSHIO
IPC: H01L21/302
Filed: 1997-01-06
Abstract: PROBLEM TO BE SOLVED: To know the kind and amount of negative ions in etching plasma and deepen the knowledge of negative ions relating to an etching process by taking out negatively charged particles incoming in a substrate electrode through an opening, applying a weak magnetic field in the vertical direction to the incoming direction to remove electrons, and passing only the negative ions to analyze them. SOLUTION: Plasma generated in a plasma chamber 21 incomes from an ion taking in small hole 25a of a substrate electrode 25 by a high frequency electric field, and passes through an opening of an electron removing magnet 37. The electron removing magnet 37 is formed by fixing two magnets to a pure iron doughnut-shaped disc, and constituted so that a vertical magnetic field of 100 gauss is generated in the vertical direction to the plasma passing direction. Of the negatively charged particles, electrons having small mass are bent with the magnetic field and cannot pass through the vertical magnetic field, but the negative ions having large mass pass through the magnetic field without being bent with the magnetic field, and are incident on an energy analyzer 30 and a mass spectrograph 32.

Title: Forming method of spiral wrap
Inventor: MURAKAMI SUZUYA
IPC: B21D11/07
Filed: 1979-01-08
Abstract: PURPOSE: To form the high accuracy wraps of an equal pitch in the radial direction with ease and high efficiency by using the snakes of varying curvatures and widths in the lengthwise direction.  
     CONSTITUTION: Snakes 13 comprise connecting the snake pieces 13' which vary in radius r of curvature and width b in the lengthwise direction and whose width b becomes narrower as the radius r of curvature becomes larger, by means of links 16. After a strip plate 14 is fitted to the end 15 of the sankes 13, the snakes 13 are rotated about the leading end 15. At this time, the radial pitch of the strip plate becomes smaller as the diameter is larger. If after this the snakes 13 are moved in the direction perpendicular to the plane of the figure and are detached from the strip plate, then spring-back occurs in the strip plate but this spring-back amount is larger as the diameter is larger and therefore the spiral wraps of an equal pitch in the radial direction are formed.

Abstract: PURPOSE:To measure the uneven state of the eyeground in real time by using a focus matching lens changing the focus matching state of an eyeground image to obtain the eyeground images of the first and second ranges of the eyeground and calculating the distance between the first and second ranges in the optical axis direction from the positions of respective focus matching lenses. CONSTITUTION:The first arbitrary range A1 on the eyeground of an eye 4 to be examined is set by regulating a setting volume and illuminated by an illumination light source 3 controlled by an illumination light source control circuit 2. The reflected light from the range A1 is incident to a photoelectric converter element 9 and a high frequency component is extracted by a high frequency component extraction circuit 11. Continuously the magnitude of the high frequency component is judged and a motor 14 is driven until the high frequency component becomes max. to move a focus matching lens 5 and the position A of the focus matching lens 5 at that time is calculated by a position operating circuit 13. Succeedingly, the second range A2 different from the first range A1 is set to calculate the position of the focus matching lens 5 where the focus matching image of the second range is obtained. Said position is set to B and the difference between the positions A, B is calculated by a position operation circuit 13 and the distance L between the first and second ranges in the optical axis direction is calculated to be displayed on a display device 15.

Title: Method for forming square cylinder with drawing
Inventor: TAKAGI MICHIO
IPC: B21D22/22
Filed: 1987-01-05
Abstract: PURPOSE:To easily constrain the generation of a canning caused at a side wall part by providing a plane pressing plate projecting at a specific height on the die face of the side wall part in the forming of a square steel plate container. CONSTITUTION:A plane pressing plate 8 is provided on the flange face 6 of a die equiv. to the conter part of each straight side part of the hole 5 of a die 4 or on a blank holder pressing face 7. The pressing plate 8 is fitted into the recessed part 9 formed on the die 4 and the projection height is made freely adjustable by the bolt 10 screwed to the die 4. In the case of forming a square shape the projection height of the plane pressing plate 8 is projected in the range of 5-25% of the steel plate thickness by the adjusting bolt 10. The gap between the die 4 and blank holder plate pressing face 7 is therefore narrowed. Now, by performing a drawing the ironing bearing becomes larger by increasing the plate thickness so much as the flange at the center part of the side wall where a material flow is bigger and the force pulling off the bending way is increased as well, so the side wall canning at this part is constrained.
