Inventor: HORIUCHI MUNETAKA
IPC: B66B9/02
Filed: 1995-12-19
Abstract: PROBLEM TO BE SOLVED: To provide a transport fixture ideal for transporting and placing a secondary conductor by providing a grip body at a contact body formed of a plurality of members having plane parts at the bottom faces and coming in contact with the peripheral surface of the secondary conductor in such a way as to clamp it. SOLUTION: In the case of fitting a transport fixture, recessed parts of contact bodies 8a, 8b are brought into contact with a secondary conductor in such a way as to hold both end parts of the secondary conductor. A bolt 11 is inserted in through-holes 13a, 13b, and a nut 12 is screwed with the end part of the bolt 11 so as to hold the contact bodies 8a, 8b with clamping pressure to the secondary conductor 3.

Title: Diaphragm device
Inventor: FUJII NAOKI
IPC: G03B9/02
Filed: 1988-12-27
Abstract: PURPOSE:To shorten a time lag necessary for the setting of a diaphragm from release by using a diaphragm plate where apertures having different diaphragm aperture diameters are pierced on both sides with respect to a diaphragm aperture positioned on a photographing optical path and turning the diaphragm plate so that the desired diaphragm aperture is set in the shortest distance. CONSTITUTION:An aperture selecting member 4 is disposed so that its own displacement is allowed in a 1st direction and a 2nd direction which is different from the 1st direction. Then, plural aperture selection parts are formed in order to select the plural diaphragm apertures 4a and 4b. In such a case, the aperture selection parts are such formed that the aperture selection part whose frequency in use is the highest of the aperture selection parts is formed at the position on the aperture selection member and other aperture selection parts are discretely disposed at the positions on the member where they are successively selected with the displacement of the aperture selection member to the 1st direction and the 2nd direction, when the aperture selection member is at a neutral position where both displacement quantities in the 1st and the 2nd directions are zero in substance. Therefore, the desired diaphragm aperture can be selected in the shortest distance. Thus, it does not take long time to set the diaphragm and the release time lag is shortened.

Title: Image processor
Inventor: OUCHI SATOSHI
IPC: H04N1/40
Filed: 1996-12-12
Abstract: PROBLEM TO BE SOLVED: To prevent the excessive elimination of the highlight of a pattern by detecting a feature value that specifies a certain original type in a first scan mode and performing the conversion of density, i.e., the elimination of texture in response to the detected feature value. SOLUTION: An original type decision circuit 8 decides the type of an original in a pre-scan mode before the main scanning is performed, and a texture level detection part 9 detects and decides the texture level of the original. A correction part 10 corrects the texture level based on the decision result of the circuit 8. Then the part 10 adds the offset to the texture level in response to the output of the circuit 8. An original of a binary structure, i. e., a dot original including the on/off states of characters or dots has a small problem even though it has the considerable rough texture. When it's decided that no characters nor dots are included, it's supposed that a pattern consists some special material and the control is required to evade the extremely rough texture of the original, i.e., not to add the excessive offset to the texture level of the original.

Title: Antidazzle type reflecting mirror for automobile
Inventor: YAMASHITA TERUO
IPC: B60R1/04
Filed: 1988-12-29
Abstract: PURPOSE:To largely change reflectivity and to obtain reflected light which is colored by sealing a guest-host type liquid crystal contg. the styryl dye expressed by the specific general formula as a guest between a transparent electrode substrate having a transparent conductive film and oriented film and a reflecting electrode substrate having a metallic film and oriented film. CONSTITUTION:An ITO film 5 and the oriented insulating film 6 are successively laminated and formed on the glass substrate 4 and an aluminum film 8 and the oriented insulating film 7 are successively laminated and formed on the glass substrate 9. The guest-host type liquid crystal 3 contg. the styryl dye expressed by the general formula (I) is sealed between these two substrates. The liquid crystal molecules attain the perpendicular orientation as the initial orientation state at the non-antidazzle time (when a voltage is not impressed) and, therefore, the light from the front face transmitted through the liquid crystal 3 is the colorless reflected light. The liquid crystal molecules are horizontal at the antidazzle time (when the voltage is impressed) and, therefore, the light from the front face passes the dye molecules made horizontal by the guest-host effect and becomes the reflected light which is colored. The dazzle prevention is thus executed. The reflectivity is largely changed by changing the impressed voltage.
