IPC: F02D41/04
Filed: 1999-02-04
Abstract: PROBLEM TO BE SOLVED: To effectively solve SOx poisoning of a catalyst by increasing reducing agent concentration and oxygen concentration in order when a condition in which sulfur component is adsorbed on a NOx adsorbing material becomes a predetermined condition, it is reacted with a reducing agent, raising a temperature of the NOx adsorbing material, and separating the sulfur component from the NOx adsorbing material. SOLUTION: In an engine 1 wherein a catalyst device 16 in which a NOx adsorbing material is used is interposed in an exhaust passage 10, and an EGR passage 17 for refluxing a part of exhaust gas to an intake passage 9 is disposed, NOx purification control by a catalyst device 16 and SOx poisoning solving control of the catalyst device 16 are performed according to an operating condition of an engine by an ECU 20. In the case of NOx poisoning solving control of the NOx adsorbing material, an air-fuel ratio is set to a rich condition, concentration of HC in exhaust gas and reducing agent of CO and the like are increased, a temperature of the NOx adsorbing material is raised, and SOx is easily separated. The air-fuel ratio is set to a rich condition again, much CO is supplied to the NOx adsorbing material, and SOx stuck on the NOx adsorbing material is separated.

Title: Method for recovering sewage energy
Inventor: TOMITA YOSHIO
IPC: C02F11/04
Filed: 1990-02-07
Abstract: PURPOSE:To recover energy with high efficiency without increasing the capacity of a digestion tank, etc., by subjecting the separated sludge separated in a settling tank to anaeration digestion in the digestion tank, recovering the energy as methane, and further, aerating a part of the digested sludge, and returning this sludge to a mixing tank. CONSTITUTION:The org. matter in the sewage is adsorbed on the sludge by a contact stabilization method without generating a component change and are concentrated in the mixing tank 1 by the return sludge activated ib an aeration tank 5. The sludge separated in a settling tank 2 is mixed with the seed sludge which is a part of the digested sludge and is supplied to the digestion tank 3 where the sludge is made into gaseous methane and this gas is recovered as energy. A part of the digested sludge discharged from the digestion tank 3 is returned as the seed sludge to the tank 3. The concd. sludge of the balance is sent to the aeration tank 5 and the aerated sludge is returned as the return sludge again to the mixing tank 1. Most of the energy possessed by the sewage is recovered as methane and the size of the treating device is reduced according to this method.

IPC: H03H9/64
Filed: 1988-02-10
Abstract: PURPOSE:To reduce the ripple caused in the pass band of a filter by cancelling the reflection or a SAW caused at the end face of an electrode and the electric reflection of the SAW caused due to the presence or a weighting static capacitance together mutually. CONSTITUTION:The interdigital electrode(IDT) 11 provided in the propagation path of a surface acoustic wave consists of three IDTs 11a-11c formed in a path of a surface acoustic wave wavelength lambda. The IDT 11c has an electrode width of 1/8 wavelength (lambda/8) of a propagation wave and connects to an input/ output terminal 12 via static capacitances C1, C2, and the IDTs 11a, 11b have nearly an electrode width of 1/4 wavelength (lambda/4) of the propagation wave and connect to either of the input and output terminals 12, and the distance between the IDTs is selected respectively nearly lambda/8. The reflection of the acoustic wave at the end face of the metallic film IDT 11 is utilized positively and the reflection of the SAW is cancelled by the presence of the static capacitances C1, C2. Thus, the ripple caused within the pass band of the frequency of the filter is reduced.

Filed: 1989-02-08
Abstract: PURPOSE:To enable the side part of front and the side part of rear to be molded with different foamable materials, while the appearance of the side part of rear is improved by a method in which after foaming raw liquid has been injected or sprayed on each molding face of a front mold and a rear mold, both molds are closed with a core nipped therebetween. CONSTITUTION:Molding is achieved with the foaming mold composed of the front mold 1 molding the side part of the front of a foamed product, the rear mold 2 molding the side part of the rear thereof and the core 3 caused to intervene between said molds. Then, after foaming raw liquid has been injected or sprayed on each molding face of the front mold 1 and the rear mold 2 opening almost horizontally, the front mold 1 and the rear mold 2 are closed with the core 3 nipped therebetween. By this manner, since the flowing length of the foaming raw liquid for molding each part of a foamed product is sufficiently reduced, and especially the molded surface of the side part of the rear may be caused to be smooth, the appearance of the foamed product may be improved. The foaming raw liquid for molding the side part of the front is made to be of a different kind of liquid from that for molding the side of the rear.

Filed: 1997-02-12
Abstract: PROBLEM TO BE SOLVED: To increase cleaning capacity by easily performing maintenance of optimum sewage treatment amount in an aeration tank and a precipitation tank without relation to supply of excess precipitation sludge. SOLUTION: The sewage treatment system is provided with a connection pipe 103a (a first sludge supply path) supplying return precipitation sludge from a precipitation tank 12 to a distribution tank 9 and also a connection pipe 103b (a second sludge supply path) supplying excess precipitation sludge from the distribution tank 9 to a mixing pipe of air for concentration. When a pump 103c is stopped, supply of excess precipitation sludge to the mixing pipe of air for concentration is not performed. Therefor, even when feed amount of sewage is reduced in particular, treatment sludge circulated among the distribution tank 9, an aeration tank 11 and the precipitation tank 12 is not affected by excess precipitation sludge and is not largely decreased. On one hand, when feed amount of sewage is increased and the pump 103c is driven, excess precipitation sludge is supplied to the mixing pipe of air for concentration.
