Abstract: A method includes forming a mixed vapor supply stream (MVSS) including measured amounts of water vapor, hydrocarbon vapor, and a carrier gas. For multiple target temperatures, the method includes (i) cooling the MVSS to form a first liquid stream and a mixed vapor outlet stream (MVOS), (ii) cooling the MVOS to condense vapor and form a second liquid stream, (iii) measuring an amount of a selected component in the second liquid stream, and (iv) calculating an amount of the selected component in the first liquid stream as the difference between the measured amounts of the selected component in the MVSS and the second liquid stream. The amount of the selected component as a function of the target temperature is analyzed to identify a lowest temperature at which the first liquid stream is expected to contain none of the selected component other than an amount soluble in the first liquid stream.

Abstract: An image forming apparatus includes a developer conveyance device to transport developer, using a positive-displacement pump to alternately generate positive pressure and negative pressure by changing a volume of an internal space thereof, a destination developer container to which the developer conveyance device transports developer, a sensor provided to the destination developer container, to detect developer in the destination developer container, and a controller to control the positive-displacement pump according to a detection result generated by the sensor. The controller disabled detection of developer by the sensor in a non-detection period that starts from a stop of the positive-displacement pump.

Abstract: A leak detecting apparatus and method by which a regulated supply of gas is delivered from an adjustable pressure regulator to a smoke generator so that smoke generated within the smoke generator and carried to a fluid system being tested for leaks is at optimal density throughout the pressure range. The leak detecting apparatus and method have particular application for testing high pressure operating systems (e.g., the engine of a turbo-charged motor vehicle). A flow transducer measures the rate at which the regulated supply of gas flows to the smoke generator. First and second pressure transducers measure the pressure of the regulated gas and the pressure of the system being tested for leaks. The system under test is visually inspected for leaks after the pressure regulator is adjusted to a pressure to create an optimal maximum flow rate and the pressures measured by the first and second pressure transducers are equalized.

Abstract: An image forming apparatus includes a developing unit and a supply amount increasing unit. The developing unit supplies oil-impregnated particles to an image carrier and develops an electrostatic latent image by a developer on the image carrier which is electrically charged to a polarity that is opposite a polarity of the developer which is electrically charged to a positive polarity or a negative polarity, based on a potential difference between a developing part and the image carrier. The supply amount increasing unit increases an amount of supply of the oil-impregnated particles to the image carrier by adjusting the potential of the image carrier, while a developing operation is not being performed by the developing unit.
