Abstract: A system for measuring size segregated mass concentration of an aerosol. The system includes an electromagnetic radiation source with beam-shaping optics for generation of a beam of electromagnetic radiation, an inlet sample conditioner with adjustable cut-size that selects particles of a specific size range, and an inlet nozzle for passage of an aerosol flow stream. The aerosol flow stream contains particles intersecting the beam of electromagnetic radiation to define an interrogation volume, and scatters the electromagnetic radiation from the interrogation volume. The system also includes a detector for detection of the scattered electromagnetic radiation an integrated signal conditioner coupled to the detector and generating a photometric output, and a processor coupled with the conditioner for conversion of the photometric output and cut-size to a size segregated mass distribution.

Abstract: A suction structure is provided for allowing refrigerant into a suction pressure region in a fixed displacement piston type compressor. The compressor includes a rotary valve. The suction structure includes a shifting device which shifts between a connecting state and a disconnecting state. The shifting device includes a valve body, a return spring, a first and a second displacement chambers, and a throttle passage. The return spring urges the valve body from a connecting position toward a disconnecting position. The volume of the first displacement chamber is displacable in accordance with an amount of a fluid inside therein. The volume of the second displacement is displaced. The fluid is filled in the first and the second displacement chambers. The throttle passage connects the first displacement chamber to the second displacement chamber. The fluid flows through the throttle passage when the volume of the first displacement chamber is displaced.

Abstract: An apparatus and method for estimating size segregated aerosol mass concentration in real time and using a single detector. A beam of electromagnetic radiation is passed through a particle stream made of a test or field aerosol. The single detector outputs an electrical signal proportional to the electromagnetic radiation scattered thereupon. The electrical signal may be conditioned to produce an integrated signal for measuring radiation scattered from all the particles in the interrogation volume, a pulse height from an individual particle within the volume, and/or a time-of-flight measurement from the individual particle. The integrated signal can be correlated to particle mass concentration. The pulse height signal and the time-of-flight signal may be converted to infer the size of the individual particle. Attendant size distributions for the particle sizes may also be obtained. Using known or assumed particle properties, the mass concentration may be estimated from the size distribution.

Abstract: Guidelines for designing lenses or systems for aerodynamic focusing of nanoparticle or cluster beams. The design process may involve obtaining a relationship between particle size, operating pressure and aperture size, and selecting the operating pressure to provide continuum flow of an aerosol beam through the aerodynamic lens. Particles having diameters less than 30 nanometer may be focused. Simulation techniques for evaluating designed lenses are also disclosed.

Abstract: An introduction passage of rotary valve has outlets for feeding out refrigerant in a suction pressure zone toward each of compression chambers. A switch portion in a shutoff state shuts off a portion of the suction pressure zone within a compressor from the outlets of the introduction passage. The switch portion includes a valve body, a working pressure chamber, and a working pressure applying portion. The working pressure chamber introduces a working pressure that is applied to the valve body so as to arrange the valve body at a communication position. The pressure in the suction pressure zone acts against the pressure in the working pressure chamber through the valve body.

Abstract: A vehicle exhaust heat recovery system includes a vapor compression type refrigeration circuit, a boiler to which the refrigerant is introduced from the refrigeration circuit and heated, and an expander for generating motive power by expanding the heated refrigerant.

The refrigerant that has been subjected to expansion is recycled to the refrigeration circuit.

Abstract: A fluid machine is served as an expansion device and a compression device. The fluid machine compresses gas in an operation chamber upon functioning as the compression device. The fluid machine expands the gas in the operation chamber upon functioning as the expansion device. The fluid machine includes a movable discharge valve served as a differential pressure regulating valve that discharges the gas from the operation chamber when the fluid machine functions as the compression device. The discharge valve is moved to a non-operation position where the discharge valve fails to function as the differential pressure regulating valve when the fluid machine functions as the expansion device.

Abstract: A power transmission mechanism that permits power to be transmitted from an external driving source to a rotary shaft of a rotating machine includes a first rotating body, a second rotating body, an armature, and a spring clutch. The first rotating body rotates integrally with the rotary shaft of the rotating machine. The second rotating body is rotatably supported by the housing of the rotating machine and is coaxially arranged with the first rotating body. The second rotating body receives power from the external driving source. The second rotating body accommodates an electromagnetic coil and has a cylindrical extended portion. The armature is arranged to face the second rotating body. The spring clutch is wound about an outer circumference of the first rotating body. An outer circumference of the spring clutch is surrounded by the extended portion of the second rotating body. The spring clutch has a first end and a second end.

Abstract: A first rotor is rotatably supported by a housing. A second rotor rotates integrally with a rotary shaft. A power transmission mechanism is capable of transmitting power from the first rotor to the second rotor. When supplied with a current, an electromagnetic coil is capable of causing the armature plate to adhere to the first rotor. In a state where the armature plate adheres to the first rotor, the spring clutch couples the second rotor to the first rotor. An urging member is accommodated in the second rotor. The urging member is located between the rotary shaft and the armature plate. Therefore, the power transmission mechanism is compact and achieves a high performance.
