摘要:
An inertial filter is placed in a fluid flow path and equipped with a particle classifying sheet having a plurality of particle classifying holes uniformly arranged. The particle classifying sheet has a sheet area larger than a fluid passage area at a site where the sheet is placed. A part of the sheet is provided in the form of a partition wall dividing the fluid flow path in two sections in a fluid passage direction to allow for classification of particles.

摘要:
An inertial filter to be disposed in the air flow path of a stream of air containing nanoparticles includes plural particle classifying sheets having plural mesh-like holes are disposed in the air flow path. The plural particle classifying sheets are stacked on each other in a manner that a part of at least one of the particle classifying sheets overlaps with the other particle classifying sheet. The inertial filter can adjust a classification diameter by adjusting a shadow area ratio on a projection view obtained by virtually projecting the plural particle classifying sheets from a downstream side to an upstream side of the air flow path.

摘要:
A method for removing and modifying a protrusion by using a short pulse laser is provided for modifying a color filter. In a color filter modifying method, a transparent substrate (2) is scanned with a beam in a parallel direction, while irradiating a protrusion (8) generated on the color filters (3-1, 3-2, 3-3) formed on a transparent substrate (2) with a beam collected by a high NA condensing lens (18), and a protrusion (8) is removed or modified.
摘要:
The object of the present invention is to provide a particle counter which can accurately count the number of particles contained in fluid where the number concentration of particles is high. The particle counter includes a particle removing portion for removing particles contained in fluid at a predetermined rate, a sensor portion for counting the particles passing through the particle removing portion, and a particle number correcting means comprising a characteristic data memory and a digital signal processor for performing correction processing to the number of the particles counted in the sensor portion by using removal characteristics of the particle removing portion with respect to the particle diameter.

摘要:
In an apparatus for ionizing and separating a gas into gas components in an inlet gas (11), a gas flowing into a flow channel of a chamber from an inlet port is ionized, and in the flow channel the gas ionized by applying an electrical field to the gas components having an ionized state by electrodes (16) (17) is separated into a cation and anion to separate a gas molecule component contained in the gas. One of the gas component such as a clean air is removed from a first outlet (12) port and the separated gas component is removed from a second outlet (13) port. A flow of the inlet gas from the inlet port is adjusted to retain the gas in the flow channel of the chamber for a predetermined or more time so that an airflow is adjusted.
摘要:
A stepping motor is rotated stepwise in angular increments by successively exciting a plurality of phases. When the stepping motor is to be stopped, the phase or phases which have been finally excited immediately prior to motor stop control are kept intermittently excited to stop the stepping motor. For starting the stepping motor again, the phase or phases being excited in the stop mode are supplied with continuous currents for an interval of time longer than the period of each single pulse applied to the phase or phases excited in the stop mode and shorter than the period in which a current flowing through the excited phase or phases become saturated, and thereafter the phases starting with a phase or phases following the phase or phases excited with the continuous currents are successively supplied with currents.
