摘要： PROBLEM TO BE SOLVED: To obtain a noncontact IC card which has superior mechanical strength against point pressure, an impact, bending, etc., is easily manufactured in simple structure at low cost, and can be reduced in card thickness with ease by providing a reinforcing plate which has an opening at the part, corresponding to the electrodes of the IC chip and joining the reinforcing plate directly to the main surface side of the IC chip where a device is formed. SOLUTION: On the IC chip 100 where a gold bump 110 is formed, the reinforcing ceramic plate 130 having the opening part at the gold bump position is joined with an adhesive 120. A silver paste electrode 160 is buried in the reinforcing plate opening part and an electrode 160 is led out of the reinforcing ceramic plate 130. The IC chip 100 is electrically connected to a silver paste wire 180 on the wiring board 170 by using an anisotropic conductive film 190. This reinforcing ceramic plate 130 is connected directly to the IC chip 100 to simplify the process and reduce the card thickness. Further, a noncontact IC card which is tolerant of mechanical destruction can be actualized.

摘要： PROBLEM TO BE SOLVED: To provide an inexpensive stereoscopic image recording and reproducing device without depending on the moving speed of image by recording and reproducing moving images for the right eye and for the left eye while synchronizing with a recording medium, time-base dividing the moving images for the right eye and for the left eye and alternately selectively outputting them as video images. SOLUTION: A liquid crystal polarization switcher 4 switches a transmitting linear polarized light component to an orthogonally crossing direction matching the timing of alternately displaying the images for the left eye and for the right eye timewise on a television monitor 1. The light of the images for the left eye and for the right eye is respectively converted to orthogonally crossing linear polarized light and transmitted through the polarized light spectacles 5 of an observer 7 and thus, the image for the left eye is perceived by the left eye and the image for the right eye is perceived by the right eye. A polarizer is mounted to the polarized light spectacles 5 so as to orthogonally cross transmission polarized light axes and the direction is matched with the transmission polarized light direction of the liquid polarization switcher 4 further. Since parallax is generated in the moving images perceived by the left and right eyes, the observer 7 perceives stereoscopic moving images.

摘要： PROBLEM TO BE SOLVED: To allow anyone to easily specify a site where large discharge may occur by visually displaying a site with small discharge occurring. SOLUTION: A bright image data storage 4 stores image data when an electrified body 1 is recorded by a television camera 3 with its surroundings bright, while first and second dark image data storages 5, 6 store image data when the electrified body 1 is recorded by the television camera 3 with its surroundings dark. Each of the first and second dark image data storages 5, 6 stores image data from the television camera 3 in time series by switching at an image switching part 7. An illumination position detection part 8 detects a position with discharge illumination by comparing the image data stored in the first and second dark image data storages 5, 6. The detection results are displayed on the same screen by an illumination position display part 9 with the image data of the electrified body 1 stored in the bright image data storage 4 overlapping thereon.

摘要： PROBLEM TO BE SOLVED: To freely enlarge and contract viewing fields without reducing the amount of sample information by detecting using an image sensing device an optical image emitted by a phosphor, and interlocking control of the electron-ray scans of the image pick-up device with adjustment of the focal length of a lens system. SOLUTION: An electron ray 3 applied to a sample 2 is projected onto a phosphor 4 by an electron lens 11, and an electron-ray image is converted into an optical image. The optical image is taken to the outside through a glass pane 5 from an electron microscope 1 and focused onto the photoelectric surface of an pick-up element 7 by an optical lens system 6. The photoelectric surface is the photoconductive film 28 of the image pick-up element 7. Charge is accumulated in the photoconductive film 28. This amount of charge is read by two-dimensional scans of electron beams 27 for measurement of the intensity of the image. The two-dimensional scans of the electron beams 27 are control led by a deflection coil 26 located inside a camera main body 8. A lens system controller 32 is interlocked with a deflection coil controller 30 to control the intervals between the scans in accordance with the rate at which the image is contracted by the lens system 6. A picture signal read is transferred to an image collecting processing device 10.

摘要： PURPOSE: To provide a two-dimensional radiation image detector improving spatial resolution and sensitivity. CONSTITUTION: The detector comprises a first element board 11 and a second element board 12. Phosphor films 51 each for converting radioactive rays into visible light are formed on a plurality of light receiving elements on each element board, 61 of the rays is converted to the visible light by the phosphor film of the board 11, 62 of the rays is incident to a region having no phosphor film of the first board, converted to the visible light via the phosphor film of the second board 12 to be transmitted through the first board and detected. The phosphor film is formed on the region having no phosphor film of the first board in the second board, and the ray incident to the detector is detected separately by the first and second boards. One image is synthesized from the two images detected by the boards of the two layers in such a manner that the spatial resolution is uniform with respect to the lateral and longitudinal arraying directions of pixels. Accordingly, the pixel area is increased by twice as large as that of prior art at the light receiving area.

摘要： PURPOSE: To obtain a video image with high S/N, high sensitivity and a wide dynamic range by revising a signal band width of a preamplifier and a resistance of a load resistor to extract a video signal of an image pickup tube depending on a scanning time in the case of slow scanning in the image pickup device using the image pickup tube. CONSTITUTION: A scanning time setting display section 15 outputs a voltage control signal corresponding to a set scanning time to a load resistor control section 13, a frequency band width control section 14, and a scanning beam deflection control section 9. A desired resistance of 1 to 100Mohms for the load resistor 11 is selected by a rotary angle of a voltage sensing pulse motor built in the load resistor control section 13. A video signal obtained by an image pickup tube is led to an A/D converter 20 via a preamplifier 10 and the frequency band width control section 14. Through the constitution above, in the case of slow scanning + band limit + high load resistor, the S/N more than twice is obtained even at a low illuminance in comparison with the intermittent operation through the synergitic effect of the band limit and the high load resistance.
