Title: Plasma accelerating tube forming method
Inventor: SUZUKI YASUO
IPC: H05H1/24
Filed: 1995-10-17
Abstract: PROBLEM TO BE SOLVED: To provide a hollow plasma pillar in which the density is lower in the position near the axis than in the peripheral part to prevent the divergence with the refraction of light by letting interfere two laser breams having the same wave length from horizontal and vertical directions and forming a plasma accelerating tube. SOLUTION: Laser beams 9, 10 are divided into two with a translucent mirror 2 and a total reflection mirror 3, then let interfere with electron beams 8 to generate an interference fringe, and plasma slabs 12 are formed at optional intervals. By passing aslant electron beams through a number of plasma slab rows formed, an alternating electric field perpendicular to the proceeding direction of the electron beam, or an undulating electric field component is obtained. By letting interfere laser beams from horizontal and vertical directions, an optical guide 11 having the density lower in the position near the axis than the peripheral plasma part 12 is formed.  For example, a hollow plasma pillar in which the plasma density is 1×10<10> /cm<3> in the peripheral part, and 1×10<14> /cm<3> in the central part, and the inner dimensions of a square pillar are about 10μm in length and width and height is 10mm is obtained.

Title: Retinal camera
Inventor: KOBAYAKAWA YOSHI
IPC: A61B3/14
Filed: 1998-10-09
Abstract: PROBLEM TO BE SOLVED: To achieve an accurate adjustment of focus with a simple structure by projecting a target for focusing onto the eyegrounds and imaging a retinal reflection image to detect the blurring of a target image. SOLUTION: Reflected light from an eyground travels on an optical path 03 of an observation imaging system to form an image of a pupil P near a bored mirror 8 with an objective lens 15 and passes through a hole part of the bored mirror 8 and a turret 16 to form an image by an imaging lens 17 again near a field lens 18. Further, the light passes through a collimator lens 19 to form a retinal image onto an imaging means 21 for observation imaging with an imaging lens 20. The resulting image is displayed on a TV monitor 24 and an image signal is stored into a memory 23. Here, a general purpose camera 25 encircled by a dotted line detects the blurring of the image of the imaging means 21 by an automatically focusing function and moves a part of the imaging lens 20 in the direction of the optical path 03 to accomplish automatic focusing.

Title: Blind integrally incorporated with solar cell panel
Inventor: ISHII TAKEO
IPC: H01L31/04
Filed: 1993-11-09
Abstract: PURPOSE:To provide a blind composed of several slats for blocking sunlight and laid in the opening part of a building, and solar cell panels each attached to the light receiving surface of each of the slats so that electric energy can be obtained from the solar energy. CONSTITUTION:In the daytime, a blind 7 is extended downward so as to block the sunlight by means of slats 701 in order to ensure its shading function, and electric power is generated from amorphous solar cell panels 11 attached to the slats 701. Then blowers 31, 37 are driven by the generated power so that an air stream is induced continuously from an air blow-off port 35 to an air suction port 39. The air stream creates air-curtains extending from the lower side 305 to the upper side 306 of a window 1 in front and rear of the blind 7 so as to effectively prevent transmission of outside heat into the building, and accordingly, the cooling or heating efficiency of the inside of the building can be enhanced.

Title: Contact exposure device having means for setting spacing between mask and work
Inventor: OKADA MASAKAZU
IPC: H05K3/00
Filed: 1999-10-26
Abstract: PROBLEM TO BE SOLVED: To provide a contact exposure device which eliminates the need for exchanging a means for setting the spacing between a mask and a work even when the works varying thicknesses are treated. SOLUTION: The means 10 for setting the spacing between the mask and the work comprises a stationary member 10a and fixed to a work stage WS and a moving member 10b. The stationary member 10a and the moving member 10b are fitted to each other by screwing. The height of the moving member 10b can therefore be adjusted by rotationally moving the moving member. The work stage WS and the mask stage (not shown in Figure) are spaced apart a prescribed distance by the means 10 for setting the spacing, by which the pressure in the space between the mask (not shown in Figure) and the work WS is reduced. Since the work stage WS and the mask stage are parted apart the prescribed distance by the means 10 for setting, the mask and the work do not come into contact with each other in spite of the pressure reduction and a gap is formed between both.  The work W is floated by air in this state to bring the mask M and the work W into tight contact with each other and exposure is executed.

Title: Method for inspecting remnant of paste for sticking protecting film
Inventor: NAKAI TAMIYOSHI
IPC: G01N21/88
Filed: 1989-11-22
Abstract: PURPOSE:To prevent attachment of dirt of commodities by confirming the remnant of paste for sticking a protecting film with the naked eyes, and selecting the optimum protecting film for the commodity based on the result of inspection which accurately represents the amount of the remnant. CONSTITUTION:As a test sample 4, several kinds of protecting films made of polyethylene are stuck to an iron enamel plate and the like. The test sample is loaded into a weather meter. After 50, 100 and 200 hours, the film is released from the test sample. This test sample is used and mounted on a mounting stage 2 and set beneath a vibrating plate 3. Colored powder 9 which is put in a sieve 5 is vibrated with a vibrator 1 and sprayed on the surface of the test sample 4. Then, the colored powder 9 is pushed to the test sample 4 with a roller 7. Thereafter, water is sprayed through a sprinkler nozzle 6. Thus the colored powder other than the sizing part is washed out. Therefore, the colored powder 9 is still attached to the part where the sticking paste remains on the surface of the test sample 4, and the amount of the remaining paste can be confirmed. That is, the optimum protecting film can be selected because the film having the narrow colored area and light concentration is good. Thus, the attachment of dirt to commodities is prevented.

Title: Subject detecting device
Inventor: SHINTANI TETSUO
IPC: G01V3/12
Filed: 1991-11-20
Abstract: PURPOSE:To substantially eliminate the place where electric waves are weak in an electric field distribution formed around a transmission cable by providing a transmitting portion with a means for varying a standing-wave generated in the transmission cable. CONSTITUTION:A transmitting portion 1A is provided with a standing-wave variation means 10A comprising high-frequency oscillators 111A-114A for producing different high frequencies and a switching means 12A for switching and driving the oscillators. The means 12A drives the high-frequency oscillators in sequence at every tmus, so that different high frequencies are transmitted to a transmission cable 2A at every tmus. The cable 2A releases leakage electromagnetic waves, around which an electric field is formed. Since the frequency varies, a standing-wave generated within the cable 2A also varies, so that the position at which the electric field is weak is varied at every tmus. That is, the place where the electric field is weak is substantially eliminated. Therefore, intruders can be detected throughout the cable 2A when passing above the cable 2A buried.
