Abstract:
A laser microscope includes a laser light emitting system which emits a pump beam and a Stokes beam having different frequencies, and a common optical fiber having one end and the other end. The pump beam and the Stokes beam emitted from the laser light emitting system are incident on the one end thereof and emitted from the other end thereof. A beam irradiating mechanism condenses and irradiates the pump beam and the Stokes beam emitted from the other end of the optical fiber, onto a sample via the objective lens, thereby making an anti-Stokes beam be emitted from the sample. A photo detector detects the anti-Stokes beam emitted from the sample. A beam selecting mechanism allows only the anti-Stokes beam of the pump beam, the Stokes beam and the anti-Stokes beam to be received on the photo detector.
Abstract:
This invention provides a laser scanning microscope in which a harmonic generator for modulating a laser beam Q having passed through an optical fiber into a laser beam Qb having a wavelength different from that of the laser beam Q, and sending the laser beam Qb to a scanning type optical microscope main body is integrally attached to the scanning type optical microscope main body.
Abstract:
A Ti/TiN adhesion/barrier layer is formed on a substrate and annealed. The anneal step is performed at a temperature within a good morphology range of 100° C. above a base barrier anneal temperature that depends on the thickness of said barrier layer. The base barrier anneal temperature is about 700° C. for a barrier thickness of about 1000 Å and about 800° C. for a barrier thickness of about 3000 Å. The barrier layer is 800 Å thick or thicker. A first electrode is formed, followed by a BST dielectric layer and a second electrode. A bottom electrode structure in which a barrier layer of TiN is sandwiched between two layers of platinum is also disclosed. The process and structures also produce good results with other capacitor dielectrics, including ferroelectrics such as strontium bismuth tantalate.
Abstract:
An inverted microscope is provided that reflects an observation light passing through an image-formation optical system upward using at least one reflection optical system and that leads the observation light to an observation path. The inverted microscope includes a confocal scanner arranged at an image surface position of the image-formation optical system, a light source for applying light onto a sample through the confocal scanner and the image-formation optical system, and a confocal image formation optical system that leads the light passing through the confocal scanner to the sample through the image-formation optical system, returns a return light from the sample to the confocal scanner along a route opposite to that for leading the light to the sample, and obtains a confocal image. A confocal observation optical system is also provided for leading the return light from the sample passing through the optical scanner to the observation optical path.
Abstract:
A method of making a resin encapsulated pin grid array which includes an IC chip mounted on a resin substrate having a plurality of contact pins on its lower surface and resin-encapsulated by injection molding. A metal heat radiating member is integrally formed on the upper surface of the encapsulating resin when the encapsulating resin is injection-molded.
Abstract:
A combustion control method wherein manipulated variables or the amounts of fuel and air in at least one combustion zone of a boiler are regulated so that both the amount of nitrogen oxides and the amount of unburned coal in the ash at an outlet of a burner furnace or at least one of them passes the regulation standards and satisfies the requirements for operating a plant. The method is characterized by varying the amounts of fuel and air in performing trial operations on manipulated variables to evaluate the nitrogen oxides at the furnace outlet, the unburned coal in the ash at the furnace outlet and the stability of combustion, and declaring as optimum manipulated variables those amounts of fuel and air used for performing the trial operations which achieve results such that the combustion is found to be stabilized, at least the nitrogen oxides at the furnace outlet satisfy the requirement and the thermal efficiency of the boiler is judged to be at the highest level by a boiler thermal efficiency judging section.
Abstract:
In acquisition of an image of cells, a focal position is accurately set at highly active cells rather than focusing on dead cells. Provided is an automatic focusing apparatus (8) used in a microscope (1) that image captures fluorescence emitted from cells to acquire a cell image, the automatic focusing apparatus (8) including a setting unit (5) that sets a luminance range indicating a region where viable cells exist on the basis of a luminance distribution of the acquired cell image; and a focus-detecting unit that detects a focal position on the basis of a luminance of an image of nuclei of the cells within the luminance range set by the setting unit (5).

The size and production costs of an optical microscope apparatus capable of blocking light or maintaining the specimen environment are reduced. The provided optical microscope apparatus includes a microscope that has a stage for mounting a specimen (A), a transmission-illumination optical system, and a detection optical system; and a housing that surrounds the microscope, wherein the housing includes a fixed housing, and a movable housing, wherein, among optical parts constituting the transmission-illumination optical system and the image-forming optical system, at least some optical parts disposed above the stage are movable, and wherein a switching mechanism is provided, the switching mechanism being configured to retract the optical parts away from above the stage when the movable housing is disposed in an open position relative to the fixed housing and to substantially align the optical axes of both optical systems when the movable housing is disposed in a closed position relative to the fixed housing.
