≪１級課題 -電気・電子工学-≫【問 1】[Claim 1]
An energy dispersion type X-ray detection device that irradiates asample with an electron beam, an X-ray, or the like and detects acharacteristic X-ray generated from a sample surface to conduct elemental
analysis, comprising:an element holder that houses a semiconductor X-ray detection
element and has a female screw having a cylindrical shape; anda finger body that houses a substrate with an initial-stage FET foramplifying a signal from the semiconductor X-ray detection element, thefinger body having a cooling mechanism and being provided with a malescrew, wherein
the element holder and the finger body are configured to be fastenedusing the female screw and the male screw to fix the semiconductor X-ray
detection element.
[Claim 2]

Conventional and typical image compression methods include JPEG
method, which is standardized by ISO. It is known that this method uses
discrete cosine transform, and assigning comparatively large number of
encoding bits will lead to provide good encoded images and good decoded
images. However, decreasing the number of encoding bits to a certain
degree will lead to noticeable block distortion, and deterioration subjectively
becomes conspicuous.
In contrast, research and development is recently becoming active formethods for dividing an image into plural bands, using a filter having ahigh-pass filter and a low-pass filter in a combined manner, and performing
encoding for each band. This filter is called a filter bank. Among them,wavelet transform coding is thought to be promising as a new technique that
may replace DCT, because, compared to DCT, it does not have any deficit ofnoticeable block distortion in a high compression rate.
For example, JPEG 2000, for which international standardization
was completed in January, 2001, employs a method in which the wavelet
transform is combined with highly-efficient entropy encoding. This hasachieved a great improvement in encoding efficiency compared to JPEG.

In more detail, the electronic paper device 26 is a well-known
self-writing type which may display predetermined information in an image
on an image display section in a voltage application state and hold it in a nopower supply state. In a state where no voltage is applied by themicrocomputer 23 via the driver to each of the pixel electrodes which form amatrix in the image display section, negatively (-) charged white particles
accumulate on the back side of the image display section, while positively (+)
charged black particles remain on the front side. The image display sectionis thus in a black colored state when it is viewed from the front side. The
driver operates based on electronic data output from the microcomputer 23.

When the driver inverts the polarity of the pixel electrodes in a required
portion of the matrix in response to the information to be displayed in animage, the positional relationship between the white particles and the black
particles is changed as appropriate. The image display section thus
displays information in an image based on the contrast of the white particles
and the black particles. In addition, the electronic paper device 26 may
hold the image displaying state as it is even in a no power supply state inwhich no voltage is applied via the driver to each of the pixel electrodes
forming the matrix in the image display section.
