Title: Method and equipment for removing nitrogen from sewage
Inventor: MINAMI TAKESHI
IPC: C02F3/34
Filed: 1988-11-18
Abstract: PURPOSE:To make installation area comparatively small and also to obtain a preferable biological denitrifying process at small volume without lowering denitrification efficiency by mixing sewage with both the circulated nitrification liquid and the returned activated sludge to perform denitrification and thereafter performing oxidations of BOD and then performing nitrification treatment. CONSTITUTION:Raw water is agitated and mixed with both the nitrification liquid circulated from a nitrification tank 12 and the activated sludge returned from a final sedimentation basin 4 in a denitrification tank 2 to perform denitrification. The discharged water is introduced into a BOD oxidation tank 11 and aeration is performed in the existence of activated sludge and BOD remaining in water is chiefly oxidized. The solid particle group with nitrification bacterial stuck thereon is housed in a nitrification vessel 12 and this solid particle is brought into contact with the discharged water sent from the BOD oxidation tank 11 under the aerobic conditions to perform nitrification treatment. Since large amounts of nitrification bacteria are held on the solid particle group having the large surface area, nitrification treatment is extremely efficiently performed even in a miniature vessel.

Title: Cap for molding honeycomb
Inventor: MUKAI TOSHIFUMI
IPC: B28B3/26
Filed: 1987-11-17
Abstract: PURPOSE:To prevent the growth of a molded form at the downstream end of a cap by a method wherein a discharging flow passage is constituted of a two-step structure consisting of an upstream side lattice forming flow passage and a downstream side stress mitigating flow passage and the width of the lattice forming flow passage is made constant in the direction of flow so as to obtain a parallel groove while said width is made narrower than the width of the stress mitigating flow passage. CONSTITUTION:A molded form, forming an integrally connected lattice in a lattice forming flow passage 2, flows into a stress mitigating flow passage 3, connected at downstream side and forming lattice type grooves. The width of the stress mitigating flow passage 3 is wider compared with the width of the lattice forming flow passage 2. An unit flow passage is cylindrical and a discharging flow passage 20, consisting of the cross-type lattice forming flow passage 2 having a length (l2) and the stress mitigating flow passage 3 having the length (l3), is connected to the downstream end of a supplying flow passage 1 having the length (l1) while both of the lattice forming flow passage 2 and the stress mitigating flow passage 3 are parallel grooves. According to this method, slip is readily generated in an interface between the flow passage and a molded form and deviating speed, which becomes the generating cause of elastic stress in the molded form, is reduced, therefore, the elastic stress, accumulated in earth, may be reduced and the amount of growth at the downstream end of a cap may be reduced.

Title: Semiconductor laser-excited solid state laser device
Inventor: SENOO TOMONOBU
IPC: H01S3/098
Filed: 1990-10-25
Abstract: PURPOSE:To contrive to improve a wavelength conversion efficiency by reducing unabsorbed excitation light entering a non-linear optical material through providing a pinhole in an optical path ranging from a condensing lens to said non- linear optical material. CONSTITUTION:A throttle plate 25 and a non-linear optical material 17 are successively arranged on the injection side of the laser excited light 22 of a laser medium 15, and the smallest possible pinhole 27 of a diameter causing no loss to a laser cavity mode coinciding with the optical axis of the laser excited light 22 is formed on the diaphragm 25. Because excitation light 21 converges into a focus in the laser medium 15 by a condensing lens 13, unabsorbed excitation light 21 not absorbed by the laser medium 15 spreads rapidly when injected from the laser medium 15. Most of the unabsorbed excitation light 21 is intercepted when the excitation light 21 passes the pinhole 27 of the diaphragm 25. Therefore, the light 21 can be prevented from being injected into the non-linear optical material 17 and the temperature rise of the material 17 under the influence of the light 21 is suppressed so that it is possible to optimize phase matching conditions to realize a stable wavelength conversion.
