摘要:
A substrate processing apparatus that performs processing by immersing a substrate into a processing liquid obtained by mixing phosphoric acid with a diluent includes a concentration sensing means for sensing the concentration of the processing liquid by measuring the absorbance characteristics of the processing liquid. The concentration sensing means includes a light-transmitting section that introduces the processing liquid into the inside to let the processing liquid pass therethrough, a light-emitting section that radiates light having a predetermined wavelength to the light-transmitting section, a light-receiving section that receives the light therefrom via the light-transmitting section, a first lens that condenses the light emitted from the light-emitting section to the light-transmitting section, a second lens that condenses the light that has passed through the light-transmitting section to the light-receiving section, and a cooling mechanism that cools at least one of these.

A challenge to be met by the invention is to provide an electronic component mounting machine that makes up an electronic component mounting line and that standardizes an operation input method, to thus enable lessening of work load on an operator during performance of operation input action, and an operation instruction method for use with the electronic component mounting machine. In electronic component mounting machines that make it possible for a single machine to perform a plurality of types of works by replacement of a work head to be built into a common platform according to a type of work, a production start button to a model change button are provided as common individual input parts in a basic operation command input part of a display panel of an operation unit regardless of a work type. Control processing and computation processing commensurate with an operation instruction entered by way of the individual input part are performed according to a work program and a computation processing program corresponding to the work head recognized by a plug-in function.

An attenuated total reflection probe has a prism and a supporter. The prism is made of an optical material which transmits light in far ultraviolet region, and has a contact plane to be in contact with a sample, and an incoming plane and an outgoing plane both not to be in contact with the sample. The supporter has an opening and is connected hermetically with the prism around the opening and eventually exposes the contact plane facing the opening. The contact plane, the incoming plane and the outgoing plane of the prism are formed such that light transmitting the incoming plane enters the contact plane at an incident angle larger than critical angle and that the light totally reflected by the contact plane goes out through the outgoing plane.

An object is to provide an electronic component mounting method in which an adequate component mounting work to which a check result is correctly reflected is enabled and it is possible to satisfy both reduction of the failure occurrence rate and improvement of the working efficiency. An electronic component mounting apparatus in which an appearance checking section which checks a board to detect existence or non-existence of a failure item, and a component mounting section which transfers and mounts an allocated mounting object component to the board in which the check is ended are integrally disposed includes a mounting availability determination processing section 28d which determines an availability of an execution of an operation of mounting the mounting object component, based on a result of detection of a failure item. In a mounting availability determining process, an availability of an execution of a mounting operation for the mounting object component is automatically determined based on preset failure patterns of the detection result.
摘要:
In far ultraviolet spectroscopy using attenuated total reflection, total reflection light is measured by using evanescent waves of total reflection light. The penetration depth thereof is equal to or larger than 150 nm in a wavelength range in the far ultraviolet range wherein the penetration depth depends on a wavelength of the far ultraviolet light, refractive index of an object to be measured, refractive index of optical material of the probe and incident angle of the far ultraviolet light at an interface between the probe and the object. The attenuated total reflection probe is made of an optical material selected so as to have the penetration depth equal to or higher than 150 nm in far ultraviolet wavelength range, and the probe makes contact with the object to be measured at the interface, and the far ultraviolet light is incident on the interface at incident angle larger than critical angle in the wavelength range so as to have the penetration depth equal to or higher than 150 nm. The total reflection light from the interface is measured, and absorbance of the object to be measured is determined.
摘要:
An optical probe consists of a first component made of a first optical material having a light transmission property in the far ultraviolet region, and a second component made of a second optical material arranged in contact with the surface of the first component. For example, the second optical material has a higher refractive index in the far ultraviolet region than the first optical material. The second component is provided, on a side in contact with a sample, with a surface totally reflecting light having incident angle equal to or larger than the critical angle. Alternatively, an optical probe has an optical material having a light transmission property in the far ultraviolet region, having a surface totally reflecting a ray of light of incident angle equal to or larger than the critical angle, at a side in contact with a sample, and the refractive index is higher near the surface than at the other parts in the far ultraviolet region. Consequently, a spectroscopic measurement becomes possible on very small solute components dissolved into water or the like in the far ultraviolet region.

In the past, the occurrence of wavelength dispersion in signals transmitted through optical fibers caused considerable problems in terms of communications at a communications bit rate of 10 Gbps or more, and particularly optical communications at 40 Gbps or more. In the present invention, an optical dispersion compensating element can be realized having a group velocity delay time vs. wavelength characteristics curve in which the extreme value of group velocity delay time is large over a broad bandwidth by composing a compound optical dispersion compensating element containing optical dispersion compensating elements in which a reflector Or multi-layer film element is disposed in opposition to the incident surface of a multi-layer film element capable of performing dispersion compensation by utilizing group velocity delay time vs. wavelength characteristics, and connecting a plurality of elements capable of performing dispersion compensation in series. According to the present invention, dispersion compensation for each channel as well as dispersion compensation of a plurality of channels is performed.
