  • Publication number: 20200171652
    Abstract: A hand mechanism grips an object more favorably, regardless of the attitude and surrounding conditions of the object. When an object is to be gripped by a hand mechanism having three or more finger portions, at least one finger portion among the three or more finger portions functions as a state-altering finger portion for altering the attitude or the position of the object while contacting the object, and at least two finger portions among the finger portions other than the finger portion functioning as the state-altering finger portion function as gripping finger portions for gripping the object in a state where the attitude or the position has been altered by the state-altering finger portion.

  • Publication number: 20200114508
    Abstract: A gripping system for gripping an object using a hand mechanism having at least two finger portions includes a specification unit that specifies a contactable portion and an unexposed portion, the contactable portion being a portion of the object that can be contacted by at least a first finger portion constituting one of the finger portions and the unexposed portion being a portion that is not exposed at the time of the determination, a first operation control unit that exposes the unexposed portion of the object, and a second operation control unit that grips the object in a state where the unexposed portion is exposed by bringing the first finger portion or the second finger portion into contact with the unexposed portion and bringing a finger portion other than the finger portion contacting the unexposed portion into contact with a predetermined surface of the object other than the unexposed portion.

  • Patent number: 7195400
    Abstract: An optical connector ferrule has an optical fiber containing hole reaching from the rear end surface near the end surface and a fine pore extending from the optical fiber accommodating hole to the end surface to be connected. A bare fiber of a polarization-maintaining optical fiber is inserted into the fine pore. Since the length of the fine pore is short, the influence of the uniformness of the adhesive in the fine pore is smaller, and therefore the stress distribution is maintained, resulting in stabilizing the polarization characteristics. A flange unit is attached to the ferrule after an optical fiber is inserted to the ferrule and fixed. Therefore the optical fiber is easily adjusted with respect to the housing in the circumferential direction around the axis, and optical fibers are connected by but joining with high accuracy.

  • Patent number: 6755574
    Abstract: An optical connector that provides a housing body 21 and a fixed part 22 that are installed so as to hold a backplane 3, and connects an optical connector plug 4b inserted into said housing body 21 via an installation hole in said backplane 3 and another optical connector plug 4a inserted into said housing body 21 from the direction opposite to that of said optical connector plug 4b, wherein flexible claws 25 projecting from both sides of said fixed part 22 engage said housing body 21 via said installation hole 30 in said backplane 3, and thereby said backplane 3 is held between said housing body 21 and said fixed part 22. Simply by adjusting the floating range (amount of floating) of the flexible claws 25 within said installation hole 30 the floating range (amount of floating) of the housing body 21 can be reliably set.

  • Patent number: 5864989
    Abstract: A ventilating window for ventilating the interior of a building or a structure such as a vehicle in a natural and gentle manner. A ventilating window for the exhaust of air is provided with a mechanism for automatically opening a window casement when the atmospheric pressure inside the window is higher than the outside atmospheric pressure, thereby dispensing with forced exhaust using a fan or the like. A ventilating window for the supply of air is provided with a mechanism for automatically closing a window casement when the atmospheric pressure outside the window is higher than the inside atmospheric pressure, thereby preventing a strong wind from blowing into the interior. A ventilating window for both exhaust and supply of air is provided with both such opening mechanism and closing mechanism.

  • Patent number: 5796888
    Abstract: According to the present invention, an optical switch apparatus is provided for switching the connections between a plurality of fixed optical fibers which are fixed and arranged on an optical fiber support base within a container filled with an index-of-refraction matching agent, and movable optical fibers provided on a movable base which is moved by a moving mechanism comprising a worm gear within the aforementioned container. In addition, a worm gear driving member and a cam driving member of a matching device are both provided on the exterior of the aforementioned container via a seal. This worm gear driving member which is connected to a control device, starts the positioning sequence and moves the movable base to a standby position following return of the movable base to a predetermined origin within the container. As a result, it is possible to prevent contamination of the index-of-refraction matching agent over a long period of time, and thereby reduce the connection loss to a satisfactory level.

  • Patent number: 5201016
    Abstract: The optical switch according to the present invention momentarily switches the optical transmission lines made of tapes in which optical fibers are laid parallel to each other. This optical switch has a main body provided at the top thereof with a plug chamber in which a stationary and moving plugs in which the end portions of the optical fibers are fixed so as to abut each other are received, and a sliding mechanism provided on the moving plug. Also, the optical switch has charged in the plug chamber thereof with an oil for reducing the connecting loss, and it has an oil-leak preventive mechanism to prevent the oil from leaking from the hole in which the push pin pressing the moving plug is inserted. Further, the optical switch is provided with a lateral-pressure adjusting mechanism which appropriately gives a lateral pressure to the moving plug by means of the push pin. Furthermore, the optical switch has a cushion mechanism to accommodate a fine vibration or the like caused as the moving plug is moved.

  • Patent number: 5078519
    Abstract: Two-stage skew adjustment is achieved by first using only the drive force of the platen roller with the pinch roller and the capstan roller drive disrupted by a gap opening mechanism to effect a large skew adjustment. Then, the gap is closed and the platen roller, which has a Teflon-resin coating thereon and a larger diameter than the capstan roller or pinch roller, effects a small skew adjustment. Thereafter, printing is effected by feeding the paper in a reverse direction to register with an inked ribbon feed of a primary ribbon using the platen roller drive and the pinch roller drive with the skew cycle repeated for each ribbon color segment to achieve improved multicolor printing registration.
