  • Patent number: 5762978
    Abstract: The device can be applied to compression machines including a turret (1), rotating around a vertical axis and fitted with a series of die holes (3) aimed at being filled with powder of granular material; pairs of punches (5,6), upper and lower punches respectively, related to each die hole (3) and guided slidably in the turret (1), engage the die holes (3) with respective counterfacing working heads (5a,6a). The device features a driving cam (9) that drives at least one of the punches (5,6) and determines the reciprocal distance between the working heads (5a,6a) of each pair of punches, in the material batching step and in the material loading step; the driving cam (9) moves axially with respect to the turret (1) so as to adjust this distance. Further cams (11,12) are provided for completion of guiding structure (15) with variable profile, which facilitates entering in the driving cam (9).

  • Patent number: 5759646
    Abstract: Proposed is an improvement in a vessel, e.g., crucible, of pyrolytic boron nitride (PBN) used, for example, in the process of molecular beam epitaxy for melting silicon and the like at a high temperature. Different from conventional PBN crucibles used for such a process, in which contamination of high-purity silicon is unavoidable by the reaction of molten silicon with PBN or a thermal decomposition products of boron nitride, the inventive PBN vessel is provided on the surface with a protective coating layer of pyrolytic graphite or a refractory metal such as platinum so as not to cause troubles due to contamination of high-purity silicon melted therein with the crucible materials.

  • Patent number: 5755340
    Abstract: The holder is used for a notepad formed of a stack of note slips which are connected with one another at one of their edges. It has a concave, arc-shaped or gutter-shaped support for the notepad. This support has two edges parallel to its imaginary generating straight line. These two edges project away from the concave support surface. One of the edges has a height (h) which corresponds roughly to the height of the notepad to be received by the holder. The distance (A) between the two edges measured along the concave support corresponds to the width (B) of the notepad to be received. The edge whose height (h) corresponds roughly to the height of the notepad projects away from the concave support approximately at a right angle.

  • Patent number: 5751400
    Abstract: The conversion system for a camera employs a conversion lever disposed at the outer side of a camera body to select a given photographic mode without need to open the camera. The conversion lever is used to shift a cam plate which is located within the camera body in order to effect vertical movement of two panorama curtains within the camera body. The cam plate may be moved into one of three positions, namely a normal photographic mode position, a first photographic mode position and a second photographic mode position. A first operating lever is actuated by the cam plate to move one panorama curtain vertically while movement of the first panorama curtain causes movement of the second panorama curtain via a second operating lever.

  • Patent number: 5749340
    Abstract: A hydraulic tappet comprises an open-ended cylinder and a piston slidably accommodated in the cylinder. One end of the piston projects out of the open end of the cylinder and engages a valve rocker. A gear mechanism is provide to effect rotation of the cylinder about its axis whilst the piston remains stationary. An oil chamber is provided within the cylinder beyond the other end of the piston. A pressurized oil space is arranged to supply oil to the chamber via a non-return valve. An oil discharge space communicates with the chamber via a pathway including an opening in the cylinder wall. The pathway is interrupted by the piston as the piston moves into the cylinder. The oil discharge space is at a pressure substantially below that of the pressurized oil space. A plurality of spaced holes is arranged in a spiral line formed in the cylinder wall but only one of the holes communicates with the oil discharge space at any one time.
