In relation to a humidity sensor sensitive to water and contamination, a sensor implementation structure that achieves both protection performance against water and contaminants and measurement performance such as humidity responsiveness is provided. A sensor structure has a mass airflow measurement element that measures a mass airflow flowing in an intake pipe, a humidity sensing element that senses humidity of air flowing in the intake pipe, a housing structural component having a connector that carries out input/output to/from outside and a terminal component of the connector, and a bypass passage that is composed by using part of the housing structural component and takes in part of the air that flows in the intake pipe, the mass airflow measurement element being mounted in the bypass passage; wherein space is provided in the housing structural component in the vicinity of the bypass passage, the humidity sensing element is mounted in the space.

A method and device for regenerating an ion exchanger can regenerate an ion exchanger easily and quickly, and can minimize a load upon cleaning of the regenerated ion exchanger and disposal of waste liquid. A method for regenerating a contaminated ion exchanger includes: providing a pair of a regeneration electrode and a counter electrode, a partition disposed between the electrodes, and an ion exchanger to be regenerated disposed between the counter electrode and the partition; and applying a voltage between the regeneration electrode and the counter electrode while supplying a liquid between the partition and the regeneration electrode and also supplying a liquid between the partition and the counter electrode.
摘要:
A process of measuring a shape while changing the relative posture of an microscopic interferometer to a sample lens which is rotated about a rotation axis is divided into a process of measuring a top surface in a state where the sample lens is supported from a back surface and a process of measuring a back surface in a state where the sample lens is supported from the top surface. By combining first shape information of a flange side surface acquired by the process of measuring the top surface and second shape information of the flange side surface acquired by the process of measuring the back surface, the relative positional relation between the sample top surface and the sample back surface is calculated.

The present invention provides a substrate processing apparatus and a substrate processing method suitable for use in an etching apparatus which etches a thin film formed on a peripheral portion of a substrate. The present invention also provides a substrate processing apparatus and a substrate processing method suitable for use in a cleaning apparatus which performs a cleaning process on a substrate which has been etched. The substrate processing apparatus for use in etching includes a substrate holder 11 for holding a substrate W substantially horizontally and rotating the substrate W, and a processing liquid supply unit 15 for supplying a processing liquid onto a peripheral portion of the substrate W which is being rotated in such a manner that the processing liquid is stationary with respect to the substrate W. The substrate processing apparatus for use in cleaning a substrate includes a substrate holder 54 for holding a substrate W substantially horizontally and rotating the substrate W, and a cleaning liquid supply unit 53 having a cleaning liquid outlet 53a which is oriented from a center of the substrate W toward a peripheral portion of the substrate W with an elevation angle of not more than 45° from a surface of the substrate W. The cleaning liquid supply unit 53 supplies a cleaning liquid to the surface of the substrate W at a flow velocity of not less than 0.1 m/s.

摘要:
First, a first exposure process is performed using dipole illumination with only a grating-pattern forming region as a substantial object to be exposed. Next, a second exposure process is performed with only a standard-pattern forming region as a substantial object to be exposed. A development process is then performed to obtain a resist pattern. A mask for the first exposure process is such that a light blocking pattern is formed on the whole surface of a standard-pattern mask part corresponding to the standard-pattern forming region. A mask for the second exposure is such that a light blocking pattern is formed on the whole surface of a grating-pattern mask part corresponding to the grating-pattern forming region.
