Title: Exhaust emission control device of internal combustion engine
Inventor: KATO KENJI
IPC: F01N13/04
Filed: 1998-07-21
Abstract: PROBLEM TO BE SOLVED: To prevent the flowing-out of unpurified NOx from a storage/reduction catalyst by the air-fuel ration variation of exhaust gas. SOLUTION: An NOx storage/reduction catalyst 7 is provided on the exhaust gas passage 2 of an engine 1. NOx in the exhaust gas is absorbed to the NOx storage/reduction catalyst 7 during the lean air-fuel ratio operation of the engine, and at the time to discharge NOx, the engine is operated in a rich air-fuel ratio, to make the air-fuel ratio of the exhaust gas flowing in to the NOx storage/reduction catalyst 7 rich.  An electronic control unit 30 carries out the secondary fuel injection not contributing to the combustion by cylinder fuel injection valves 111 to 114, in the expansion stroke or the exhaust stroke of the cylinders, while the engine is operated in the area from a theoretical air-fuel ratio to the air-fuel ratio 20, when the engine operation air-fuel ratio is changed from the lean air-fuel ratio to the rich air-fuel ratio operation, to make the air-fuel ratio of the exhaust gas flowing in to the catalyst 7 rich, so as to prevent the flowing-out of unpurified NOx from the catalyst 7, when the air-fuel ratio in the engine operation is changed.

Title: Controlling method for concentrator
Inventor: KAWANISHI TOSHIO
IPC: C02F11/12
Filed: 1989-08-08
Abstract: PURPOSE:To hold the concn. of concentrate uniform by detecting the flow rate and the concn. of raw water and calculating the amount of water filtered through a membrane module and also allowing the concentrate to flow out via an overflow weir. CONSTITUTION:Raw water 3 is filtered by a filter membrane module 8 and produced filtrate passes through a takeout pipe 9 and is taken out to the outside of a concentrator 1. Concentrate produced in the inside of the concentrator 1 passes through a takeout pipe 14 and is sent to a concentrate takeout tank 15. Further the flow rate and the concn. of raw water 3 allowed to flow through a conduit 4 are detected by a flowmeter 6 and a densitometer 7. While the flow rate of filtrate allowed to flow through the takeout pipe 9 is detected by a flowmeter 11, a controller 21 controls a pump 10 so as to take out filtrate at such flow rate that the concn. of concentrate taken out though the takeout pipe 14 is regulated to the prescribed value. Thereby the water level of the concentrator can be held at a certain level.

Title: Optica recording medium
Inventor: MIYAMOTO MAKOTO
IPC: G11B7/2407
Filed: 1993-08-20
Abstract: PURPOSE:To improve the reliability of tracking by changing groove widths within the same medium. CONSTITUTION:The surface of the medium is irradiated with two sub-beams 2 and one main beam 1 and tracking servo is executed by a difference in the reflected light quantity of the two sub-beams from the grooves 4 formed on the optical recording medium 4 as a tracking error signal. Information is reproduced with this optical recording medium by the main beam 1. The widths of the grooves 4 are changed within the same medium in correspondence to the shapes or/and optical properties of the recorded information. The specified tracking error signal level is thereby obtd. within the medium. Setting of the tracking error signal at a sufficiently high level is consequently possible even if the tracking error signal is dropped by the contamination of the optical head and the surface of the disk substrate, etc., owing to the long term use and, therefore, the reliability of the tracking is improved.

Title: Slider for linear guide device
Inventor: KAWAGUCHI TAKAHIRO
IPC: F16C29/06
Filed: 1996-08-06
Abstract: PROBLEM TO BE SOLVED: To prevent the deformation of end face forming parts, form a direction changing path with accuracy and attain smooth ball circulation by thickening an upper face forming part to the upper face of a horizontal part of a block body so as to make a pair of end face forming parts, thickened to end faces, continuous with each other. SOLUTION: End face forming parts 49 and side face forming parts 48 are injection molded to movable body fitting faces 41 provided at the upper face of a block body 40. At the same time, an upper face forming part 50 is thickened, and a pair of end face forming parts 49 positioned at both end faces of the block body 40 are connected by the upper face forming part 50. The upper face forming part 50 thereby restricts the deformation of the end face forming parts 49, so that the end face forming parts 49 can closely adhere to the block body 40 without generating a clearance. A moving block is therefore prevented from being deformed with the lapse of time. The deformation of the end face forming parts 49 are also prevented, so that a cover body 5 can be tightly fixed to the end face forming parts 49.  A direction changing path of a ball is formed with accuracy so as to attain smooth infinite circulation of the ball.
