摘要:
A torque limiting device for a compressor. An input shaft of the compressor is connected to the torque limiting device so that the power source driving the compressor will not be affected if abnormal conditions cause the compressor to generate an excessive load. A flexible connector is located between the power source and the compressor. The flexible connector is deformed when torque is applied to the compressor input shaft. When the applied torque exceeds a predetermined value, a spring is permitted to expand axially, which uncouples the compressor from the power source. The torque at which the device uncouples is stable and predictable.

A compressor mounted on a vehicle is disclosed. The compressor includes an apparatus for transmitting rotational power from an engine to drive shaft of the compressor via a pulley. The apparatus has a spring coupled to one of the pulley and the drive shaft. A deformable ring is coupled to the other one of the pulley and the drive shaft. The deformable ring is deformed by heat. The spring and the deformable ring are being held in abutment against each other by the force of the spring so as to transmit the rotational power to each other. A contact ring is interposed between the spring and the deformable ring. The contact ring has a rigidity larger than that of the deformable ring. The spring and the contact ring frictionally contact one another to generate the heat that deform the deformable ring when load generated in the drive shaft is in excess of a predetermined value.

The present invention provides a fuel feeding apparatus and method for improving the controllability of mixing process and mixing ratio of fuel and combustion air, and a combustion system and method for effecting new combustion properties. The fuel feeding apparatus of the combustion system has fuel feeding means, combustion gas extraction means, steam supply means, mixing means and fuel gas introduction means. The combustion gas extraction means extracts combustion gas of a combustion area therefrom. The mixing means mixes the fuel of fuel feeding means with at least one of combustion gas extracted from the furnace and steam of a steam generator. The fuel gas introduction means introduces a mixed fluid of combustion gas, steam and fuel to the combustion area as a fuel gas, and allows the fuel gas to be mixed with the combustion air. A step of mixing the fuel with the combustion gas after extracted from the furnace and a step of mixing the fuel gas with the combustion air are stepwisely carried out, so that the controllability of mixing process and ratio of the air and fuel is improved. Such a control of fuel gas flow enables control of characteristics of flame and production of flame with new properties in the combustion area.

A fluidic apparatus includes a pulley driven by an engine, torque limiting means disposed in the pulley and adapted to shut off the transmission of driving force transmitted by the pulley when overload is applied thereto, and a driving shaft driven by the torque limiting means. The torque limiting means includes a boss formed coaxially with the pulley, a collar disposed integrally and coaxially with the driving shaft, and a coiled spring adapted to hold outer peripheral surfaces of the boss and the collar by tightening with a predetermined tightening allowance. With the torque limiting means, if abnormal loads should be applied to the driving shaft, there hardly occur internal breakages, or the like, in the fluidic apparatus. In addition, because the torque limiting means has such a simple construction, the fluidic apparatus is down-sized and reduced in manufacturing cost.

摘要:
A laser magnetic immunoassay (LMIA) technique is presented which combines the high detection sensitivity of the radioimmunoassay (RIA) technique with the simplicity of particle agglutination (PA) technique. The LMIA technique dispenses with the separation step of bound and free species (B/F separation), yet provides detectivity of the order of picogram of viral species per milliliter of analyte solution. The procedure includes of the steps of: preparing a superparamagnetic-labeled body of antigen or antibody; subjecting a specimen sample and the magnetic-labeled body to a specific immunoreaction to produce a reacted body; subjecting the reacted body containing both bound and free species to a spot magnetic field gradient; irradiating the spot with a laser beam; measuring the intensity of the outgoing light from the spot; and making a quantitative determination of the virus according to the time difference in the outgoing light signals generated by bound and free species.
摘要:
An in-situ laser magnetic immunoassay ("LMIA") method which eliminates the step of B/F separation generally required in the labeling method of immunoassays. The laser magnetic immunoassay permits a quantitative determination of a target immunological substance, for example, an antigen, an antibody, lymphocytes, viruses, tumorous cells and infections cells, in an analyte solution containing both bound and free species. A transitory increase in the magnetophoretic scattering of laser beam is observed when the analyte solution contains magnetic-labeled, bound target analyte, while no such increase is observed in a control test solution, containing only the relevant reagents. A magnetophoretic LMIA apparatus is provided which includes a magnetic gradient generating device which forms an integral part of the in-situ LMIA.
