Title: Laser wavelength converting element and converting device
Inventor: HARASAKI AKIKO
IPC: G02F1/37
Filed: 1997-03-20
Abstract: PROBLEM TO BE SOLVED: To improve wavelength conversion efficiency by extending the interaction length between a basic wave and a wavelength-converted wave in nonlinear optical crystal by the wavelength converting element which utilizes the crystal. SOLUTION: An incidence end surface 1a and a projection end surface 1b of the nonlinear optical crystal 1 are partially coated with totally reflecting optical thin films 2a and 2b; and the remaining part of the incidence end surface 1a and the remaining part of the projection end surface 1b are coated with reflection preventive films 3a and 3b for the basic wave and the wavelength- converted wave respectively. The wavelength conversion efficiency increases in proportion to the square of the crystal length, so the totally reflecting optical thin films 2a and 2b reflect the light zigzag to extend the effective crystal length, thereby improving the wavelength conversion efficiency.

Title: Waste water treatment apparatus
Inventor: SEKINE TOSHIRO
IPC: C02F3/32
Filed: 1987-04-09
Abstract: PURPOSE:To efficiently treat waste water, by dividing the interior of a container into upper and lower parts and constituting the upper part as an algae part where adhesive filamentous algae proliferate while constituting the lower part as a heterotrophic part where a heterotroph proliferates and allowing both parts to communicate with each other by a communication passage to form an endless flow passage where a water recirculation apparatus is arranged. CONSTITUTION:When air is introduced through an air diffusion pipe under pressure, a mixture of waste water and microbes is recirculated through an endless flow passage in the direction shown by an arrow. During the day, the adhesive filamentous algae (f) adhered to the upper adhesive surface (f) of an algae part (a) absorb sun rays to perform photosynthesis and, at the same time, absorb oxygen supplied by the air introduced under pressure, re-aeration and photosynthesis to proliferate. As a result, BOD, N and P in the waste water are removed to purify the waste water. In a heterotrophic part (h), aerobic bacteria absorb the residual oxygen from the algae part (a) to proliferate and BOD, N and P are similarly removed to purify the waste water. During the night, aerobic bacteria and adhesive filamentous algae (f) proliferate by oxygen supplied by the air introduced under pressure and re-aeration to purify the waste water.

Abstract: PURPOSE:To improve lubricity as well as recording density and crack resistance and to obtain good reliability by packing a magnetic material and lubricative material into the fine pores of an alumite film obtd. by subjecting Al or Al alloy to an alumite treatment. CONSTITUTION:After the Al or Al alloy is subjected to an ordinary pretreatment, the Al or Al alloy is subjected to the alumite treatment to form the alumite film thereon. The magnetic material is packed by an electrolytic deposition method and/or electroless deposition method into the fine pores of such film and after the lubricative material is packed into the inside upper layer of the fine holes, the film is subjected to a sealing treatment at need. The electrodeposited matter of a metal sulfide and/or metal soap or perfluoroalkyl compd. is preferable as the lubricative material. The magnetic head has lubricity even if the head moves and rubs on the film according to such constitution and, therefore, the head can be operated without damaging the surface. Since the magnetic material exists in the fine pores of the hard alumite film, various kinds of information can be satisfactorily maintained. Wear resistance, flawing resistance and smoothness are thereby improved and the reliability is obtd. This material is favorably used for a magnetic disk substrate, etc.
