Filed: 1977-12-29
Abstract: PURPOSE: The effective adsorption area of magnetic material with respect to the rotary disk of a magnetic separator is increased, the amount of magnetic material collected from the water under treatment is remarkably increased, and the adsorbed magnetic material is taken out efficiently.  
     CONSTITUTION: Waste water supplied from inlet 10 to treatment tank 18 passes the back side of the transport passage of scraper 3 and flows in the passage formed in the gap on rotary disk 1, the most part of which is immersed in water, in the rotational direction of disk 1 as shown by the arrow. Magnetic material contained in the waste water is arrested during this time by magnet 12 on disk 1, and with the rotation of disk 1, the arrested magnetic material is scraped off into the transport passage by scraper 3. Scraped magnetic material 17 is moved up by gilled belt 2 along scraper 3 to the upper part of tank 18, and then it is separated from belt 2 by another scraper and is discharged outside via shoot 9. Water flows from the gap between belt 2 and the transport passage and is discharged from waste water outlet 11.

Filed: 1985-07-19
Abstract: PURPOSE:To prevent diffusion of impurities, by providing a reverse conducting type compound semiconductor emitter layer, which is laminated on a reverse conducting type compound semiconductor graded layer and has a layer that is equal to or wider than an energy band gap on the surface of said graded layer. CONSTITUTION:In a semiconductor device, a one conducting type compound semiconductor base layer is provided. A non-doped impurity-diffusion preventing layer comprising the same compound semiconductor is laminated on the one conducting type compound semiconductor base layer. A reverse conducting type compound semiconductor graded layer, which forms a part of a emitter layer, is laminated on the impurity-diffusion preventing layer. The energy gap of the graded layer becomes large in comparison with the one conducting type compound semiconductor layer as the graded layer is separated in the direction of the film thickness from the impurity-diffusion preventing layer. A reverse conducting type compound semiconductor emitter layer is laminated on the reverse conducting type compound semiconductor graded layer. The energy band gap of the emitter layer is equal to or wider than that in the surface of the graded layer. Therefore, impurity diffusion from the base layer to the emitter layer is not required to consider.

Title: Curl preventing device
Inventor: TAKANI HISANARI
IPC: B65H67/08
Filed: 1981-10-01
Abstract: PURPOSE:To simplify the manipulation of unwinding a yarn from a bobbin or the like with the use of a curl preventing device, by arranging a creased cloth- like member around a cop so that the creased cloth-like member is in contact with all of the peripheral surface of the cop or all but excepting at least a part thereof. CONSTITUTION:A cloth 2 is arranged around substantially all peripheral surface of a cop 5, leaving an opening part 6 left thereon. The next cop 5 is arranged in the same way so that its opening part 8 opposes the opening part 6 of the cop 5. Thus, a yarn lightly touches the cloth provided with creases which covers the periphery of the cop 5, when a yarn is wound off, so that a suitable tension for extracting the yarn is brought about for preventing the yarn from curling. Particularly, the cloth 2 shrinks due to its elastic action when the cop becomes small, so that the cloth 2 always touches the outer surface of the cop, thereby the yarn is effectively prevented from curling. Further, since the opening part 6 is provided, the change between the cops 5, 7 may be smooth by made by tying the trailing end of the cop 5 with the leading end of the cop 7.
