In a circular accelerator, a magnetic pole edge portion of a bending electromagnet into and from which a charged particle beam enters and exits is provided with endpacks. A first protrusion is provided at that part of each end pack which is radially outside the equilibrium orbit of a center energy beam, while a second protrusion is provided at that part of each end pack which is radially inside the equilibrium orbit of the center energy beam. The shapes of the first and second protrusions are set so that the betatron oscillation numbers of beams of different acceleration energies may be held constant or become linear to the energies. In case of emitting the charged particle beam out of the circular accelerator, the change of a tune attributed to the change of the beam orbit can be statically corrected, the tune is linearly changed, and an adjustment of the emission of the beam becomes easy.

An object of this invention is to provide a method for assaying, predicting or assessing drug metabolism by effectively detecting (a) mutation(s) in a gene coding for UGT. A gene coding for UGT comprises 5 exons, and since the regions of exons 2 through 5 are common to each isoform of UGT1, by assaying a mutation in the common regions, particularly a mutation in exon 5 region, and further adding the detection of (a) mutation(s) in a plurality of exon regions, mutations of UGT1 gene can effectively assayed. A nucleic acid chip using nucleic acid probes is used as a way of detecting (a) mutation(s).

The purpose of the invention is to enable a crawler tractor to brake and stop certainly without applying a load to an engine and a driving mechanism, and without complicated operation. An operation link links a conic linkage (53) which links a steering wheel (7) with a main speed change lever (55) of the crawler tractor, and with an operation mechanism of a brake pedal (54). A neutral return mechanism for the operation link is provided. The operation link neutral return mechanism comprises a hook-like cam lever (61). When the brake pedal is depressed, the main speed change lever is moved to its neutral position before braking force occurs, and then, the brake is actuated. Accordingly, engine brake is used effectively, and the brake can be miniaturized.

An inclined plate coupled membrane bioreactor for treating feed water having excessive level of nutrients in particular chemical oxygen demand and total nitrogen and suspended solids has an aerobic bioreactor for nitrification and aerobic biodegradation in which membranes are submerged for permeate extraction, and an anoxic bioreactor for denitrification within which the inclined plates are outfitted to confine as much anoxic sludge as possible. An air oxygenating and an air scouring are continuously provided to the aerobic bioreactor to maintain a desired aerobic environment and to mitigate membrane fouling while an intermittent air blowing is provided to the anoxic bioreactor to blow out gaseous content generated through denitrification and to rectify the uniformed flow along the inclined plates. The aerobic sludge is recycled to the lower compartment of anoxic bioreactor and the supernatant of anoxic bioreactor is collected as weir effluent and delivered to the downstream aerobic bioreactor. Permeate is intermittently extracted from the membranes by a suction pump. There is no excess sludge withdrawn from the inclined plate coupled membrane bioreactor throughout the experiment.

It is intended to contribute to the solution of environmental problems caused by destroying the ozone layer and serious problems concerning the food resources in the 21st century by isolating a photoreactivating enzyme from an ultraviolet light-tolerant rice plant, thus acquiring information on the photoreactivation mechanism of the plant which still remains unknown mostly, and constructing an ultraviolet light-tolerant plant with the use of a cloned gene. Genes encoding a photoreactivating enzyme originating in rice plant, in particular, a gene encoding a protein as specified in the following (a) or (b): (a) a protein comprising the amino acid sequence represented by SEQ ID NO:1; and (b) a protein comprising an amino acid sequence derived from the amino acid sequence (a) by deletion, substitution or addition of one to several amino acids and having a photoreactivating enzyme activity.

摘要:
A partitioning member for dividing a connecting pipe into at least two exhaust passageways is provided in the connecting pipe, which is attached to an exhaust side of a silencer. A valve mechanism is operable to vary the passageway area of one of the exhaust passageways. With this structure, for example, when an engine is rotating at low revs, exhaust gas is discharged from the exhaust passageway without the valve mechanism, while when the engine is rotating at high revs exhaust gas is simultaneously discharged from the exhaust passageway having no valve mechanism and a passageway provided with the valve mechanism. Therefore, it is possible to reduce exhaust noise when the engine is rotating at low revs.

A controller of an IRD generates a provisional ID for uniquely identifying an Event within the unit. Then, an Event within the unit is read from a Resource Schedule Board (RSB), and a record ID (Event ID) of the Event is extracted. A provisional ID, which is different from the registered record IDs within the related unit, is searched for. The searched provisional ID is set to be the record ID and is combined with a global unique ID (GUID) of the unit, thereby generating an Object ID. As a result, the Object ID for uniquely identifying the Event within a bus is speedily determined.
摘要:
A high pressure fuel injection system for an internal combustion engine includes a fuel feed pump which pressurizes fuel to a given feed pressure during the engine being operated, while immediately stops pressurizing the fuel when the engine is stopped. The system further includes a high pressure supply pump connected in series to the fuel feed pump for further pressurizing the fuel supplied from the fuel feed pump to a higher pressure. The system further includes a high pressure fuel reservoir which receives the high pressure fuel from the high pressure supply pump and supplies it to fuel injection valves for injection therefrom. A pressure relief valve is connected to the high pressure fuel reservoir at its one side and to the fuel feed pump at its other side. The pressure relief valve is arranged to be held closed when the given feed pressure is applied thereto from the fuel feed pump, that is, when the engine is operated. On the other hand, the pressure relief valve is arranged to be immediately opened to release the pressure in the high pressure fuel reservoir in response to absence of the given feed pressure from the fuel feed pump, that is, when the engine is stopped. With this arrangement, leakage of the high pressure fuel via the fuel injection valves is effectively prevented.

The present invention relates to crystals of 1-kestose which is a fructooligosaccharide, and it is an object of the present invention to provide high-purity 1-kestose crystals having no hygroscopicity and a method of producing the crystals. Methanol is added to an aqueous solution containing as a main ingredient 1-kestose with a purity of 80% or more, and the mixture is then dried. Methanol is further added to the mixture to obtain 1-kestose crystals with a purity of 90% or more. An aqueous solution with a purity of 70% or more is concentrated, and 1-kestose microcrystals are added to the concentrate obtained to separate 1-kestose crystals with a purity of 94 to 99.9%.
