Abstract: A method and apparatus thereof for collecting control data for the production of replacement dental parts. The method includes the steps of imaging a body area and a replacement part with a single imaging device which is arranged to take a simultaneous picture of the body area from different angles during one exposure. The pictures are developed and scanned with a reading device which generates digitized data of the imaged body area and the replacement part to be applied in that area. The digitized data is transmitted to computer equipment which automatically reproduces the body area and replacement part on a screen. A computer program calculates spacial relations data of surfaces of the body area and replacement part and the data is used as control data in making and fitting the replacement part in the human body.

A character candidate is selected corresponding to each segment of the ink data segmented at the segmentation position candidates by referring to the recognition dictionary and calculating a distance value between each of the segments of the ink data and a selected one of the character clusters.

Abstract: A rolling mill comprising at least two work rolls supported by chocks (4, 40) mounted so as to slide, with clearance, between two fixed guide faces (13a, 13b). Each chock (4, 40) is thrust laterally against the guide faces (13a, 13b) in order to take up the clearance when in service. Each chock (4, 40) is surrounded by two intermediate pieces (6a, 6b) mounted so as to slide without clearance along the corresponding guide faces (13a, 13b). These intermediate pieces are rigidly locked vertically with the chock (4) so as to move with it. Lateral thrustors (7) are interposed between at least one side of each chock (4) and the facing intermediate piece (6b) in order to push the chock back against the other intermediate piece (6a) and corresponding guide face (13a). The two guide faces (13a, 13'a) against which the two chocks (4, 4') of a roll (2) are pressed define a reference plane (P1) for the positioning of the axis of the roll (2) with the possibility of sliding parallel to that plane (P1).

Abstract: A nonvolatile semiconductor storage device in which a composite gate of a floating gate memory cell transistor and a gate electrode of a peripheral MOS transistor are formed in the same lithography process and a manufacturing method thereof. A polycrystalline silicon film and an ONO film are formed on a well region through a gate oxide film and a tunnel oxide film. A polycrystalline silicon film is formed after removing the ONO film in the right region. A floating gate and a control gate of the memory cell transistor and a gate electrode of the select transistor are formed with photoresist as a mask. Thereafter, ions of impurities are implanted and diffused in a transverse direction, thereby to form an impurity diffused layer. With this, since the impurity diffused layer is formed by transverse diffusion of impurities after the tunnel oxide film is formed, it is possible to prevent deterioration of the film quality of the tunnel oxide film.

Abstract: A plate-like washer of generally annular shape and a method of using the washer for pre-tensioning. The washer is adapted to be placed between a fastening element, used to attach two pieces to form a coupling, and a piece to be fastened. The washer is manufactured from a shape-memory metal whose upper transformation temperature is higher than the highest use and assembly temperature of the coupling. The thickness of the washer is adapted in view of the length and pre-tensioning need of the fastening element, as well as the expansion of the washer at the upper transformation temperature. The washer is actively heated to its upper transformation temperature and undergoes a phase transformation which expands the washer and pre-tensions the coupling to the desired degree.

The respective vehicles in the train comprise bogies supporting a car body resting thereon, includes devices for tilting the car body in relation to the bogies, for indicating a track curve, and a control system for controlling the tilting of the car body in dependence on the geometry of the track curve.

The curve-geometry data about the track section, previously stored in the memory is used for controlling the tilting of the car body during the next passage through curves within the track section.
