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.

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.

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.

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.
