  • Patent number: 6065288
    Abstract: The hydraulic control system disclosed herein employs a pair of combination poppet/spool valves to control the operation of a hydraulic cylinder driven from a bidirectional pump. Flow introduced through the source port of one valve lifts the poppet of the other valve on its way to one side of the cylinder which in turn opens a throttling port to modulate return flow from the other side of the cylinder.

  • Patent number: 6065414
    Abstract: The invention includes new hull systems and watercraft. In particular, the invention provides a watercraft hull (10) that has a pivot axis (22) forward of the hull waterline fore-aft center line (24). That pivot axis (22) will be the deep water point of the hull and provides a fulcrum point around which the hull turns during a direction change. The forward pivot axis (22) surprisingly imparts high manoeuvrability (i.e. the ability to execute turns of reduced radius) relative to prior systems, even at low speeds.

  • Patent number: 6062748
    Abstract: In case of printing a stamp logotype in a constitution in which a distance from a printing position to a cutting position is relatively short, it is designed to prevent useless space from being formed at the top region of a receipt and to appropriate relatively wide area for a stamp logotype printing region. A printer controller controls a head and a cutter so that, when a length of the stamp logotype is longer than a distance L from the printing position of the head to the cutting position of the cutter, the image of the stamp logotype is divided into a first logotype A equal to the distance L and a remaining second logotype B, so as to have the logotype A printed on the receipt before a preceding receipt is cut, and the logotype B printed on the receipt after the preceding receipt is cut.

  • Patent number: 6058100
    Abstract: Grooves and lands are provided to a magneto-optical disk so as to be alternately arranged, and recording bit strings are formed on the grooves and lands respectively so that information is recorded. Moreover, pit rows are formed on boundary sections between the adjoining grooves and lands so that address information of a recording/reproducing track is recorded, and the pit rows are formed every other boundary section. When the grooves and the lands are scanned as the recording/reproducing track by a light, an address of the recording/reproducing track is read out from the pit rows, and successively, discrimination is made whether the recording/reproducing track which is scanned by an optical spot is the groove or the land. This prevents crosstalk which causes inclusion of address information in the next pit rows, thereby, making it possible to obtain accurate address information.

  • Patent number: 6051174
    Abstract: An extrusion system for providing a foamed material in which a material such as a polymer material is supplied to an extruder for movement through a rotating screw member. The material is placed in a molten state and a foaming agent, such as a supercritical fluid, is introduced into the extruder at a selected pressure so that a two-phase mixture of the molten material and the foaming agent is formed. The foaming agent is then diffused into and dissolved in the molten material to form a single-phase solution which is forwarded from a solution formation to a nucleation device. A thermodynamic instability is induced through a rapid pressure drop, e.g., higher than 0.9 GPa/s in the nucleation device to nucleate microcells in the solution. A further shaping device, e.g., a die, can be used to produce a foamed material of a desired shape.

  • Patent number: 6052484
    Abstract: A degree of frequency and a comparison difference value are used as an amount of feature that is to be inputted to a discrimination circuit so as to discriminate the kind of regions. The degree of frequency is represented by the smaller of two sums, that is, the sum of absolute values of the density-level difference between pixels adjoining in the line direction of the pixels within the specific region and the sum of absolute values of the density-level difference between pixels adjoining in the direction orthogonal to the line of the pixels, which is obtained by a frequency-degree extracting circuit. Further, the comparison difference value is represented by the comparison difference between a maximum value and a minimum value in the density levels of all pixels within the specified region, which is obtained by the comparison difference circuit.
