Title: Production of ferrite powder by spray roasting
Inventor: YAMANA YOSHITAKA
IPC: H01F1/34
Filed: 1991-08-26
Abstract: PURPOSE:To obtain ferrite powder excellent in crystallinity (high reactive) by reducing the residual chlorine in the ferrite powder product and approaching the reaction temps. of the chlorides relatively to one another. CONSTITUTION:Metal chlorides are spray-roasted to produce Mn-Zn or Ni-Zn ferrite powder. In this case, the ferric ion incorporated in the soln. of the chlorides constituting the ferrite to be supplied to the spray roasting stage through the concentration stage is reduced to ferrous ion, and the mixed chloride soln. suppressing the ferric ions is spray-roasted to produce the ferrite powder. Consequently, the capacity of a roasting furnace is increased, the energy cost is reduced, the residual chloride in the obtained soft ferrite powder is reduced, the device is not corroded, the servie life of the device is prolonged, the product quality is improved, and an industrially advantageous effect is produced.

Title: Adsorbent and water treatments using it adsorbent
Inventor: SASAKI NORIAKI
IPC: B01J20/20
Filed: 1989-09-14
Abstract: PURPOSE:To efficiently adsorb and treat the soluble components such as humus in water at extremely low cost at large amounts by mixing organic substance with incineration ash of sludge and granulating this mixture and thereafter sintering the granulated bodies and bringing waste water or potable water into contact with the porous sintered adsorbent. CONSTITUTION:Organic substance (e.g. polyacrylic acid and PVA, etc.), having thickening effect is sufficiently mixed with incineration ash of sludge. This mixture is granulated at about 0.5-10mm diameter by the binder effect of the organic substance. These granulated bodies are sintered at about 800-1000 deg.C to make organic substance into ashes. Then a porous sintered adsorbent having many holes in the inside is obtained. Thereby both the area in which the adsorbent is brought into contact with waste water and potable water and the area for adsorbing the soluble components are increased and also adsorbing performance can be remarkably improved. The soluble components such as humus in water are adsorbed to this porous sintered adsorbent and efficiently removed from waste water or potable water at extremely low cost at large amounts.

IPC: G01J1/42
Filed: 1983-12-16
Abstract: PURPOSE:To enable the detection even of a 1-10mum light by a method wherein a micro bridge is formed of the titled conductor, and its width, length, and thickness are formed to specific values. CONSTITUTION:The gap between two conductor thin film electrodes 111 and 112 is used as a weak link 12 by bridging with a material having a smaller electron density than metals, and therefore a smaller reflectance, and through which a 1mum or more light can be effectively incident. For this purpose, it is necessary to use a superconductor single crystal thin film of low carrier concentration for this bridge part, which is set at 0.5-2mum in width and length, and at 2,000Angstrom  or less in thickness. Decrease in the width and the thickness of this bridge part to less than 0.5mum can not provided characteristics as a superconductor, and increase to more than 2mum can not provided characteristics as a weak link. On the other hand, if the thickness is increased to more than 2,000Angstrom , the characteristics as a weak link can not be obtained because of no reach light to the lower surface.
