  • Patent number: 8038378
    Abstract: A tape type binding apparatus includes a cutter portion formed in a U-shape inside which a paper staple is held, a paper table formed with a drawing hole through which cutter blades of the cutter portion can be inserted, a pair of pressing members arranged on respective sides of the drawing hole, and a pressing piece arranged below the center of the drawing hole. The cutter blades and leg portions of the paper staple penetrate a stack of sheets placed on the paper table by moving down the cutter portion, the pair of pressing members folds the leg portions of the paper staple to inner sides by moving toward the center of the drawing hole through rectangular holes formed on respective cutter blades, and the pressing piece presses and bonds the folded leg portions by relatively moving up with respect to the paper table.

  • Patent number: 7982937
    Abstract: The micro mirror unit includes a substrate, on which are provided a micro mirror reflecting light, a torsion bar supporting the micro mirror, a frame rotatably supporting the torsion bar, and a deformative supporting part which deforms itself to lift the frame away from the substrate and supports the frame in such a lifted condition. This arrangement makes it possible to realize an increased space between the micro mirror and the substrate, thereby realizing an enlarged mirror tilt angel, without increasing the thickness of the sacrifice layer.

  • Patent number: 7982957
    Abstract: In an optical apparatus according to the present invention, the lens thicknesses and curvature radiuses of respective first lenses are optimized so that beam waist positions of optical beams emitted from the respective first lenses of a lens array are independently changed according to aberration of a second lens, and the focal position deviation due to the aberration of the second lens is cancelled by a difference between the beam waist positions, which is given on the lens array side. As a result, it is possible to suppress, at a low cost, variations in focal positions of the optical beams which are emitted from respective ports of the lens array to be condensed by the common lens.

  • Publication number: 20100298093
    Abstract: This apparatus is provided with a clutch mechanism 14. The clutch mechanism 14 is interposed between an engine 11 and a transmission 15, and is coupled to a clutch pedal 28. An operating mode of the clutch mechanism 14 changes in conjunction with a change of an operating position of the clutch pedal 28. In the case that an execution condition is met, the apparatus lowers a maximum operating speed of the clutch mechanism 14 in comparison with a state in which an execution condition is not met. The execution condition includes the following execution start condition that “the operating position of the clutch pedal 28 is a position setting the clutch mechanism 14 to a disengaged state, and a changing speed of the operating position of the clutch pedal 28 in an engaging direction at a time of setting the clutch mechanism 14 to an engaged state from the disengaged state is equal to or higher than a predetermined starting speed”.

  • Patent number: 7340128
    Abstract: A housing 20 is equipped for supporting, from a side, a platform of a wavelength selection device comprising an input/output port 10, a collimator 11, an expanding optical system 12, a spectroscopic element, a collecting optical system 14 and a micro electro mechanical system (MEMS) mirror array 15. Because the above noted optical member is supported from the side only, influences of a thermal expansion is limited to the height direction of the optical member and the optical axis direction. By these aspects, the influence of thermal expansion is limited to a two-dimensional from a common three-dimensional, thereby enabling a design of a countermeasure to an influence of a thermal expansion. Also, the support from the side does not create a dead space thereby making the wavelength selection device compact.

  • Patent number: 7330617
    Abstract: A wavelength selective optical switch of the present invention separates a WDM light emitted from an input port of an input and output optical system, according to wavelengths, by a diffraction grating, and thereafter, condenses the lights of respective wavelengths on MEMS mirrors respectively corresponding to the respective wavelengths, in a mirror array, to reflect them by a condenser optical system, to thereby switch optical paths for the respective lights. The condenser optical system is configured by combining a plurality of lenses whose focal distances are different from each other, and positions in an optical axis direction of the lenses are adjustable by a slide mechanism. Thus, despite an error in the focal distances of the condenser lenses, in a mounting angle of a spectral element or the like, a beam pitch at the condensing positions of the lights of respective wavelengths can be coincident with a mirror pitch in the mirror array.
