摘要:
A microscope that illuminates a sample with light from a light source through an objective lens and makes it possible to observe the sample through the objective lens includes, a minute aperture that is disposed in an optical path between the light source and the objective lens and disposed at a position of an image side focal plane of the objective lens or a position conjugate therewith, a position adjustment member that adjusts the position of the minute aperture so as to make light from the light source incident on the sample with the Brewster angle through the minute aperture, and a polarizer that is disposed in the optical path between the light source and the objective lens, produces linearly polarized light, and illuminates the sample with the linearly polarized light.

In an imaging device according to the present invention, each pixel cell 12 of an image sensor 10 has a four-transistor structure created by adding only one column-resetting (X-resetting) transistor to a normal three-transistor active pixel sensor (APS). This design significantly reduces the pixel size. In the process of reading pixel signals, the period of time for reading pixel signals for constructing one frame of normal image is divided into smaller sections, during which the pixel signals of pixels that are receiving ID light are gradually and repeatedly read out. In this process, the electric current to the readout amplifier in the pixel cell 12, the variable-gain amplifier in the output section 14 and other components is supplied only at those columns where the pixel signals are being read out, whereby the power consumption is suppressed. Thus, in an imaging device for capturing an image and acquiring ID information from an optical beacon present within the captured image, the power consumption is lowered and the pixel density is increased.
摘要:
A mesh (M) having an ellipsoid shape or a shape close to the ellipsoid shape is attached to an electrode (EL1) among electrodes (EL1 to ELn). Voltages of the later-stage electrodes (EL2 to ELn) are appropriately set. With this arrangement, a local negative spherical aberration generated by the mesh (M) is cancelled out with a positive spherical aberration. This optimizes an electric field distribution. As a result, this realizes an electrostatic lens whose acceptance angle is extended to about ±60°.

It is intended to provide a composition containing wild watermelon extract. More specifically speaking, it is intended to provide an active oxygen scavenging agent containing wild watermelon extract, a method of producing the same and a method of using the same, and a moisturizing agent containing wild watermelon extract, a method of producing the same and a method of using the same. Attention is paid to the facts that wild watermelon juice per se employed as an active oxygen eliminator shows an activity of eliminating active oxygen about 10 times higher citrulline, which is contained in wild watermelon juice, at the same concentration and that wild watermelon extract has not only the ability to eliminate active oxygen but also a favorable moisturizing effect. Thus, there have been developed an active oxygen eliminator and a moisturizing agent as well as foods, cosmetics, bathing preparations, hair care products, drugs and quasi drugs containing extract of wild watermelon being a native of Kalahari Desert in Africa.

摘要:
According to the present invention, the polypeptide of theobromine synthase derived from coffea arabica and the gene encoding said polypeptide are provided. As theobromine synthase participates in biosynthesis of caffeine, caffeineless coffee would be obtained by preparing a transformed plant, wherein expression of gene encoding said enzyme is inhibited.
