  • Publication number: 20100316835
    Abstract: A textile having high fluorine adhesion rate, and excellent water- and oil-repellency can be obtained by a method of producing a treated textile, comprising steps of: (1) preparing a treatment liquid comprising a water- and oil-repellent agent which comprises at least one fluorine-containing compound selected from the group consisting of a fluorine-containing polymer or a fluorine-containing low molecular weight compound, (2) adjusting pH of the treatment liquid to at most 7, (3) applying the treatment liquid to a textile, (4) treating the textile with steam, and (5) washing the textile with water and dehydrating the textile, wherein the treatment liquid comprises a thermally gelling substance.

  • Patent number: 6411298
    Abstract: A viewpoint is set on an intersection of two arbitrary multi-planer reconstruction (MPR) images, a line of sight is displayed on a plane including either one of the two MPR images, and the geometric positional relationship of the two MPR images, the intersection thereof, the viewpoint and the line of sight is designated with a position input device such as a mouse to thereby enable the geometric positional relationship to be rearranged.

  • Patent number: 5900878
    Abstract: With respect to a stacked three-dimensional image, a point of view and a first projection plane are set, a central projection image is obtained according to a central projection method, and this image is shaded to obtain a first pseudo-three-dimensional image as if the image was observed under an endoscope. Then, a second projection plane is set with a positional relation so as to be perpendicular to the first projection plane and a second pseudo-three-dimensional image is obtained by projecting the same stacked three-dimensional image according to a parallel projection method and performing shading. An updated position of a new view point is obtained by using the second pseudo-three-dimensional image.

  • Patent number: 5883933
    Abstract: A three-dimensional image is displayed on a display in a central projection method based upon a viewpoint which is placed at the inside of an object and a line of sight. In this case, a plurality of tomographic images interposed between the viewpoint and a projection plane are sequentially arranged and displayed on a display screen. Polygon visual field frames are formed at points of intersection of projection lines forming a polygon pyramid and each tomographic image, and the visual field frames are displayed on the display screen. Thereby, the position of the viewpoint and the line of sight with respect to the currently-displayed three-dimensional image showing the inside of the object can be easily detected, and the part of the object which is being displayed can be easily recognized.

  • Patent number: 4346574
    Abstract: A mechanical lock device dispensing with a key capable of unlocking a dead bolt from outside the room when pushbuttons of a number r out of a total number of n are depressed and a locking and unlocking bar of a lock unit and a locking and unlocking member connected thereto are rendered rotatable. The locking and unlocking member is fitted in a control slider. In the control slider, there is disposed a control pin which controls the transmission of the sliding movement of an intermediate slider to the dead bolt. The intermediate slider can be operated by turning a grip. The control pin is controlled by a sub-control slider. In the lock unit, there are disposed two sliding plates which can be carried in accordance with the movement of a permutation driving plate.

  • Patent number: 4125005
    Abstract: A mechanical lock device dispensing with a key, wherein a locking and unlocking bar associated with at least one lock unit and a locking and unlocking pawl connected to such bar can be angularly rotated by depressing, in a proper order, pushbuttons of a number r out of a total number n, whereby anybody can operate from outside a dead bolt in a manner to withdraw the same from the mortise. The locking and unlocking pawl is held in engagement within a cutout formed in a control slider fitted in a stem portion of the dead bolt and also in a plurality cutouts formed in the stem portion of the dead bolt and having a larger width than the cutout formed in the control slider. The control slider can be operated by turning a grip. The dead bolt itself can be operated from inside the room irrespective of the position where the locking and unlocking pawl is disposed. The dead bolt can be fitted into a mortise and the lock units can be reset by the reciprocating motion of a lever operated by turning a knob.
