Abstract: There is provided an oxidizing catalyst located in the upstream of the exhaust gas purifying catalyst. The catalyst capacity of the oxidizing catalyst is set so that, in the relationship between a value obtained by dividing exhaust flow velocity by the catalyst capacity (exhaust flow velocity/catalyst capacity) and catalyst activatibility, when the exhaust flow velocity is exhaust flow velocity at the time of idle operation of the internal combustion engine, the catalyst activatibility is maximum (prescribed maximum activation range) and the value obtained by dividing the exhaust flow velocity by the catalyst capacity is maximum or close to the maximum.

Abstract: An engine control system includes an EGR device 10 which connects an exhaust passage Ex and an intake passage I and has an EGR valve; an intake throttle valve 41 placed in the intake passage I; and an engine control unit which is provided with an engine operation data calculator A1 accumulating mileages of a vehicle or an engine operation period, a fuel injection controller A2 controlling a fuel injection amount and a fuel injection timing, an EGR controller A3 controlling an opening of the EGR valve; a throttle valve controller A4 controlling an opening of the intake throttle valve; and an EGR passage cleaning controller A5 which delays a fuel injection timing Tn, increases an opening ? g of the EGR valve, and reduces an opening ? s of the intake throttle valve when the total mileage or the total operation period calculated by the engine operation data calculator becomes equal to a predetermined threshold.

Abstract: A steering gearbox mounting structure having an intermediate bracket mounts a steering gearbox for steering wheels of a vehicle on a subframe of the vehicle. The intermediate bracket has a breakable portion which breaks when a force greater than a predetermined force is applied to the breakable portion to provide an impact absorbing stroke of an engine of the vehicle. The breakable portion may have a thin portion such as a plate or a recess portion and is more breakable in the traveling direction than the width direction. First and second intermediate brackets may be used which include first and second kinds of breakable portions that are breakable in different modes, respectively.

Abstract: A catheter which allows injection into a target region without imposing large burden on a medical patient can be provided. A catheter (1) is used by being inserted from outside of a body into a blood vessel and a distal end thereof being reached inside of a heart, that is a target region, while a proximate end thereof remaining outside of the body. The catheter (1) is configured in a way so that an injection mechanism (5) conducts injection into myocardium from inside of a heart while a forceps mechanism (3) holds myocardium inside of the heart. In the forceps mechanism (3), a grasping portion (13) provided at the distal end of the catheter (1) opens and closes in conjunction with manipulation at a first handling portion (11) provided at the proximate end of the catheter (1).

Abstract: An exhaust gas purifying device for an engine according to the present invention includes a NOx absorbing catalytic converter provided in an exhaust path of the engine, an exhaust light oil adding injector which supplies a reducing agent component into the exhaust path, a control unit which executes the rich spike operation that controls an air-fuel ratio to the rich side per predetermined time, which adds the HC component to the NOx absorbing catalytic converter, and which heats to an S purge temperature or higher so as to eliminate a sulfur component absorbed by the NOx absorbing catalytic converter, and a catalyst temperature measuring sensor which measures the temperature of the NOx absorbing catalytic converter, wherein the control unit controls an operation cycle of the rich spike operation based on the deviation of the S purge temperature with respect to the temperature measured by the catalyst temperature measuring sensor.

Abstract: An exhaust cleaning device includes a NOx storage reduction catalyst storing NOx when an air-fuel ratio of an inflowing exhaust gas is lean and releasing the stored NOx when the air-fuel ratio of the inflowing exhaust gas is rich; an air-fuel ratio changing unit; a reducing agent supplying unit which adds a reducing agent to the NOx storage reduction catalyst; a temperature detection unit which detects a temperature of the NOx storage reduction catalyst; a poisoning recovery timing judging unit which judges a timing for executing a SOx poisoning recovery process of releasing SOx from the NOx storage reduction catalyst; and a control unit.

Abstract: An albumin preparation that prevents onset of hepatic encephalopathy caused by conventional amino acid preparations and enhances an effect of improving the symptoms is provided. The albumin preparation containing amino acids is characterized in that a content of albumin is 0.01 to 1.0 w/v %, a content of plurality of amino acids containing branched amino acid is 5 to 10 w/v %, a content of the branched amino acids is equal to or more than 30 w/w % on the basis of the content of total amino acids and further, the Fischer ratio (branched amino acid/[phenylalanine+tyrosine] (molar ratio)) is equal to or more than 20.

Abstract: An electric power steering apparatus for a vehicle includes a rack shaft having a rack of gear teeth formed at one end portion thereof and an externally threaded screw formed at a portion thereof excluding the toothed one end portion, a pinion meshing with the rack, a ball-screw mechanism having a nut threadedly engaged with the screw via balls, and an electric motor having a hollow motor shaft extending around the rack shaft and connected to the nut such that an assist torque generated by the electric motor is transmitted from the motor shaft via the nut to the rack shaft. The nut is disposed between the rack and the electric motor. This arrangement ensures that the electric motor and the electric power steering apparatus can be assembled easily and efficiently.

Abstract: A forced regeneration device which performs regeneration of a particulate filter includes oxidation catalysts (23, 24a) disposed upstream from the particulate filter or in said particulate filter and a burner (30) located upstream from the oxidation catalysts and operable switching between a combustion mode for combusting a fuel spray by inflammation to raise temperature of exhaust gases in an exhaust passage and a fuel supply mode for supplying only a fuel spray to the exhaust passage without inflammation. After the burner operates in the combustion mode, the burner operation is switched to the fuel supply mode.

Abstract: A balloon catheter capable of expanding a narrowed site of a blood vessel in the vicinity of a curved part of the blood vessel, and of easily adapting the shape of the balloon to the shape of the curved part of the blood vessel. The balloon has a shape with a curved part, and the outer portion of the curved part (the shaded area) formed so as to have a smaller film thickness as compared with the remaining portion of the balloon is stretched by an amount larger than the remaining portion of the balloon. The difference in stretch amount between the outer portion of the curved part of the balloon and the remaining portion of the balloon becomes larger as the internal pressure of the balloon is increased. Accordingly, the extent of curve of the balloon can be controlled arbitrarily by controlling the internal pressure of the balloon.
