Title: Infrared ray detector
Inventor: KUWANO YUKINORI
IPC: G01J5/02
Filed: 1982-10-20
Abstract: PURPOSE:To raise detection accuracy by eliminating shifting due to heat in the relative position by means of making with the same material the vibration material that constitutes an infrared ray passing section and a section that does not pass infrared ray. CONSTITUTION:When piezo electric vibrators 4 and 5 vibrate with specified frequencies, the state that the infrared ray passing section 9 of opposing sections 6 and 7 overlap mutually by opposition and the state that a section 8 where the infrared ray does not pass and the section 9 where infrared ray passes overlap mutually are repeated periodically, and the infrared ray that passes through a convex lens 2 is periodically interrupted.

Title: Apparatus for pressurized up-flow treatment of waste water and its usage
Inventor: ONO TAKEO
IPC: B01D29/88
Filed: 1987-07-23
Abstract: PURPOSE:To enable an efficient bulk treatment of an original waste water by attaching an air waste-water supply pipe, an air/treated-water discharge pipe and an air charge/ discharge pipe to a closed vessel inside which packed beds consisting of packing particles and a space including a collecting part for wash-concentrated waste water. CONSTITUTION:Packed beds 21 and 22 consisting of packing particles and a space A including a collecting part for wash-concentrated waste water is arranged inside a closed vessel 11. An air/waste-water supply pipe 1 which is led to the bottom part of the packed bed, an air/treated-water discharge pipe 2 which is led to the surface of the packed bed and an air charge/discharge pipe which is led to the space A are also attached to the vessel 11. That is to say, the packed beds are used efficiently in an ideal condition as a whole, because the original waste water can be allowed to flow first through a coarse particle bed and then through a fine particle bed. And a treatment duration becomes longer, because the captured amount of microbes and SS become larger. Further, a stable operation is possible, because the packing particles do not move in case that bubbles due to the original waste water or microbe treatments stick to the packing particles.
