Title: Method and device for cleaning acidic river
Inventor: KAWASHIMA NORIHIRO
IPC: C02F1/68
Filed: 1990-01-10
Abstract: PURPOSE:To efficiently and economically clean acidic river water by passing the acidic river water through a reverse osmosis membrane unit to separate the water to desalted water and concd. water, bringing the desalted water into contact with an alkali material to neutralize the water and discharging this water to the rivers. CONSTITUTION:The raw water taken from the acidic rivers is pressurized and is filtered by a pressure filter 4 and thereafter, the water is pressurized to a high pressure by a high-pressure pump 6 and is passed through the reverse osmosis membrane unit 7, by which the water is separated to the desalted water having the pH higher than the pH of the raw water and the concd. water. The desalted water is introduced into a neutralizing column 10 packed with the alkali material essentially consisting of calcium carbonate or lime by which the desalted water is neutralized. The neutralized and cleaned water is discharged to the rivers. On the other hand, the concd. water is introduced into an iron oxidizing column 11 where an oxidizing agent, such as ozone, is supplied to the water to oxidize the iron to tervalent iron ions. The water is thereafter treated in a neutralizing tank 13 and finally the supernatant liquid of a ferric hydroxide thickener 15 is discharged to the rivers.

Title: Magnetic head
Inventor: HANDA TSUNEO
IPC: G11B5/265
Filed: 1983-01-13
Abstract: PURPOSE:To record and reproduce to and from a recording medium whose disk diameter is small with high track density, by forming an erasing gap of an erasing head core by a high magnetic permeability thin film and a high magnetic permeability bulk material. CONSTITUTION:An I-bar of an erasing core is constituted of a high magnetic permeability thin film instead of a bulk material, and a high magnetic permeability thin film 15 is formed to about 1mum-50mum film thickness by means of spattering, vapor-deposition, etc. on a non-magnetic supporting body 13. According to such a constitution, it can be considered that the I-bar of the erasing core does not exist, therefore, even if a distance between a recording and reproducing gap and an erasing gap becomes small, there is room for placing a head core, and a saturation magnetization of the high magnetic permeability thin film 15 is remarkably larger than a saturation magnetization of ferrite, therefore, a recording medium of a high coercive force can also be erased exactly, the erasing capacity is also high, and also it can cope enough with converting a disk to a small diameter.
