Title: Method and equipment for production of salt and fresh water from sea water
Inventor: KAJITA HIROO
IPC: C02F1/12
Filed: 1981-07-17
Abstract: PURPOSE:To easily produce a natural salt at a low cost and to obtain fresh water, by mixing  sea water with highly-pressurized gas and atomizing the mixture into very fine particles by an  improved fuel injector, and then cooling the formed steam into water drops. CONSTITUTION:Sea water A is poured through a water-pouring opening C into a sea water vessel B having pressure-resistant structure up to a water level of about 75-80% by its whole  capacity at any time. On the other hand, highly-pressurized air D is forcedly introduced through a forcedly-introducing hole E into the vessel B, so that atmospheric pressure inside the  vessel 2 is held at about 3-5kg/cm<2>. In this way, the sea water A and the air D are independently let flow into an atomizer F, formed into very fine parrticles, and then ejected into an  evaporation chamber G. In the chamber G, a cylindrical body H, whose surface temperature is  held at a necessary high level (about 100-120 deg.C), is slowly rotating, so that water content in  the very fine-grained atomized sea water A sprayed to the surface is immediately evaporated  and raised inside the chamber. Consquently, salt content is crystallyzed within a short period,  let adhere to the surface of the cylindrical body H and then scraped off by a meansI. On the  other hand, the raised steam is introduced into a cooling pipe J inside the vessel B, cooled by heat-exchange with the sea water A, and then collected as fresh water.

Title: Printed circuit board
Inventor: FURUKAWA TETSUHIRO
IPC: H05K3/22
Filed: 1997-04-30
Abstract: PROBLEM TO BE SOLVED: To reduce errors in the distinction work of electrical components for recycling and improve the working efficiency by a method wherein the address indication pattern of the 1st electrical components which can be reused and the address indication pattern of the 2nd electrical components which are difficult to be reused are different. SOLUTION: The electrical component address indications 1 of limited life components such as varistors, arrestors, etc., whose stress hysteresises of actual usages are difficult to understand are printed with squares surrounding them. On the other hand, the electrical component address indications 2 of unlimited life components such as input terminals, etc., which have no stress and deterioration while they are actually used are not surrounded by squares. Or, the parts 3 of the limited life electrical components which show their approximate outlines are painted out and the indication parts 4 of the unlimited life electrical components are not painted out.  Thus, by making the address indications 1 and 3 of the limited life components and the address indications 2 and 4 of the unlimited life components different from each other, those components can be discriminated from each other easily when they are put into the distinction work for recycling.
