摘要:
Provided is a method for preparing a fluid containing size-controlled particles that is optimized with respect to use of a target fluid as a matrix fluid under conditions approximating actual conditions. In a preferred embodiment, size-controlled SiO2 particles are obtained by mixing and dispersing SiO2 starting particles having various sizes in a N2 carrier gas followed by fractionation with a fractionator. The size-controlled particles are electrostatically collected by a porous member from the carrier gas flow. Ultrasonic vibrations are then applied to the porous member while a HCl matrix fluid flows through the porous member loaded with the size-controlled particles. This causes release of the size-controlled particles from the porous member and their admixture and dispersion into the HCl matrix fluid.

Provided is a safe method for qualifying the cylinder valves on gas cylinders, which method can also clean the cylinder valve when necessary. Compressed gas residing in a gas cylinder is discharged through the flow path of a cylinder valve with the cylinder valve on the gas cylinder in an open position. During this process ultrasound vibrations from the generator are applied to the cylinder valve and the number of particles in the outflowing gas is counted by a detector. The cleanliness of the cylinder valve is evaluated based on the detected value of the number of particles provided by the detector. When the detected value exceeds a standard value, the application of ultrasound vibrations, counting of the number of particles, and evaluation of the cleanliness are repeated until the detected value reaches or falls below the standard value.

An ultrasound probe (3) of an ultrasound diagnostic apparatus (1) includes an acceleration sensor (5) provided for outputting acceleration information for use in obtaining an angle of the ultrasound probe at the time of diagnosing a subject. The acceleration information is converted into angle information of the ultrasound probe by an angle conversion section (11). The ultrasound diagnostic apparatus (1) includes a monitor (4) for displaying a diagnosing image of the subject obtained with the ultrasound probe (3), and a body mark (16) corresponding to the diagnostic mode selected at the time of diagnosing and a probe icon (15) placed at an angle corresponding to the angle information with respect to the body mark (16) are displayed on the monitor (4). This makes it possible to provide an ultrasound diagnostic apparatus which can display an angle of the ultrasound probe at the time of diagnosing the subject.

摘要:
An air supplying apparatus for supplying a clean room with air having a conditioned cleanliness, temperature and/or humidity includes an air control unit for discharging the controlled air, and an air outlet duct connected to an air outlet of the air control unit so as to receive the conditioned air from the air control unit through an opening which opens in a direction different from the direction of flow of air through the air control unit. The air outlet duct is formed from one or more perforated sheets having a multiplicity of air outlet apertures. The cross-sectional area of the air passage formed in the air outlet duct preferably progressively decreases towards the downstream end of the duct. A joint duct, which guides air in a direction different from the directions of flow of air through the air control unit and through the air outlet duct, may be connected between the air control unit and the air outlet duct.
