Title: Cage rotor of induction motor
Inventor: NAKAMURA ATSUO
IPC: H02K17/16
Filed: 1995-02-24
Abstract: PURPOSE: To eliminate the deterioration in a dynamic balance even at high-speed rotation by preventing the movement of a secondary conductor in the slot of a stacked core. CONSTITUTION: A cage rotor 10 is provided with a stacked core 14 which is formed from the laminate of a plurality of magnetic thin plates and which is fixed on a rotary shaft and a plurality of secondary conductors 20 placed in a plurality of slots 18 which are formed in the axial direction along an outer face 16 of the stacked core 14. Between the wall face of each slot 18 and each secondary conductor 20, a very small space 24 is formed by casting. Nearly entire part of each space 24 is filled with filler member 26 which is made of resin. The filler member 26 is made by putting a liquid impregnant into the small space 24 and then soldifying it. The filler member 26 holds the secondary conductor 20 firmly in the slot 18 and prevents the movement of the secondary conductor 20 caused by centrifugal force.  Because of the existence of the filler members 26, the dynamic balance of the cage rotor 1 can be surely achieved.

Abstract: PURPOSE:A slurry including iron oxide dispersed in water is agitated and the iron oxide is separated by sedimentation to remove the supernatant, further agitation is effected and stopped, the new supernatant is removed, thus effecting the concentration of iron oxide slurry in high efficiency. CONSTITUTION:Iron oxide and an appropriate amount of water are stirred in a slurry tank provided with a stirrer to disperse the iron oxide, then the agitation is stopped, the mixture is stood for a prescribed time and the supernatant is discarded. Further the same amount of water as the discarded supernatant is added and smililar operations are repeated, then water washing is finished and the supernatant is discarded. Then, the remaining slurry, after the supernatant removal, is stirred and stopped, then, the newly formed supernatant is discarded. The same operations are repeated. As a result, as shown in the figure, the average solid concentration in the sedimentation and separation tank can be achieved finally about 65wt%. Subsequently, the resultant slurry is charged in a filter bag and stood for one day to effect further concentration by 5wt%.

Title: Document producer
Inventor: UEDA YASUSHI
IPC: G06F17/21
Filed: 1984-02-29
Abstract: PURPOSE:To improve considerably the degree of freedom in case a document including half-em characters is printed vertically by designating these half-em characters as composition or non-composition characters and performing printing according to said designation. CONSTITUTION:The numeric characters forming a character string ''December, 2'', for example, are equal to half-em characters designated as composition characters in case the vertical writing is designated for production of a document. In such a case, the fonts (basic character fonts) 61 read out of a KPM30 are converted into display fonts shown by codes 62 in a vertical writing display mode. (The display fonts 63 of a horizontal writing display mode are shown for reference.) Then the images of corresponding fonts are shifted to the em center position if said character string is not equal to the half-em characters. Then the fonts 71 read out of the KPM30 are converted into display fonts shown by codes 72 in the vertical writing display mode. (The display fonts 73 of the horizontal writing display mode are shown for reference.) Thus it is possible to have a screen display coincident with a print image even in a vertical writing display mode.
