  • Publication number: 20050205231
    Abstract: A molding device includes a lower mold unit and an upper mold unit. A molding cavity is defined between the mold units. The lower mold unit has a storing chamber connected to the molding cavity. The upper mold unit has a damper chamber connected to the molding cavity. A pressurizing rod is inserted into the damper chamber. The pressurizing rod is actuated by a cylinder. When a pushing rod pushes molten metal in the storing chamber to the cavity, an excess amount of the molten metal enters the damper chamber. Therefore, the molding operation is reliably performed even if an excessive amount of molten metal is injected into the storing chamber. Further, the pressurizing rod pressurizes the excess amount of metal in the damper chamber.

  • Patent number: 6818280
    Abstract: A diamond is provided which is subjected to an improved rectangular brilliant-cut producing a facet configuration having an optimal shape for the purpose of increasing the visual-perceptible reflection ray amount. In the rectangular brilliant-cut diamond, the bezel facets at the four crown vertexes each is bent along the diagonal line parallel to the girdle, to yield the facet configuration in which the bezel facet is divided into the lower bezel facet and the upper bezel facet. The upper crown angle of an upper bezel facet can be made smaller than the crown angle of a lower bezel facet, and hence even without altering the crown height, by making the table facet slightly smaller, the tilt angles from the horizontal of the star facets and the second bezel facets, both provided with intense reflection, can be made small and the areas thereof can be made large.

  • Patent number: 6795762
    Abstract: A steering apparatus controller for an electric power steering apparatus, which includes an electric motor for generating assist torque for assisting steering of a steering wheel and the steering apparatus controller is designed to execute a feedback control of the applied drive voltage to the electric motor based on the detection result of the actual current that flows through the motor. A sensor detects the actual current to produce the detection result. When detecting an abnormal decrease of the drive voltage of the sensor, a voltage controller maintains the applied voltage to the electric motor at the voltage at a predetermined time before the drive voltage abnormally decreased.

  • Patent number: 6729435
    Abstract: A control apparatus of an electric power steering system has first to fourth calculators and an abnormality detector. The first calculator calculates an assist current command value, which corresponds to assist force for reducing steering force of the steering wheel, based on the steering torque of the steering wheel. The second to fourth calculators calculate a compensation current command value, which corresponds to compensation force for compensating for movement of the steering wheel, based on the angular velocity of the steering wheel that has been estimated based on the terminal-to-terminal voltage of the motor. The abnormality detector detects an abnormality of the terminal voltages of the motor. When the abnormality detector detects an abnormality, the second to fourth calculators substitute zero for the steering wheel angular velocity and then calculates the compensation current command value.

  • Patent number: 6704632
    Abstract: A vehicle steering apparatus controller that enables a sub-computer having a capacity lower than that of a main computer to recognize computation results in the same control cycle as the main computer. A main computer of the controller computes an auxiliary torque command value of a steering motor based on the torque of a steering wheel and the velocity of the vehicle in a main control routine. A sub-computer of the controller computes a value equivalent to the command value based on the torque and the vehicle velocity in each cycle of a sub-control routine, which is longer than that of the main control routine. The sub-computer includes a first comparison circuit for comparing the command value and the torque in each cycle of the main control routine and a second comparison circuit for comparing the command value and the equivalent value in each cycle of the sub-control routine.

  • Patent number: 6696807
    Abstract: A control apparatus of an electric power steering system has calculating means, controlling means, determining means suppressing means, canceling means. Calculating means calculates an assist current value that corresponds to the assist force based on steering torque of a steering wheel. Controlling means executes assist control of the motor based on the assist current value. Determining means determines an abnormality in the circuit. Suppressing means suppresses the assist control when an abnormality in the circuit is determined. If the determination of an abnormality has continued longer than a predetermined time since the suppression of the assist control, the suppressing means opens relay means that permits electric power to be supplied to the motor. When it is determined that the circuit returns to normal with the assist control suppressed, the canceling means cancels the suppression of the assist control.

  • Publication number: 20030228389
    Abstract: The molding device comprises a lower mold unit and an upper mold unit. When the upper mold unit approaches the lower mold unit, a molding cavity is defined between the lower and upper mold units. The lower mold unit has a storing chamber that is. communicated with the molding cavity. The lower mold unit comprises a pressure-decreasing mechanism and a pushing mechanism. A molten material is stored in the storing chamber. When the molding cavity is formed between the lower mold unit and the upper mold unit, the pressure-decreasing mechanism decreases pressure in the molding cavity. Afterwards, in sync with the operation that the upper mold unit pushing down a lower mold-holding member of the lower mold unit, an injection rod of the pushing mechanism pushes out the molten material in the storing chamber to the molding cavity. As a result, the efficiency of the molding operation is improved.

  • Publication number: 20030092068
    Abstract: The object of the present invention is to provide an agent for specific adsorption of type 5 adenoviral vector to undifferentiated blood cells which enables infection with a viral concentration that does not impart toxicity to undifferentiated blood cells, without requiring the construction of a new viral genome, or special modification of viral particles such as biotination, etc. The above objective has been achieved by providing a polypeptide which has affinity for both adenovirus and undifferentiated blood cells. Use of the polypeptide of the present invention enables improved efficiency of adenoviral vector-mediated gene transfer of any gene to undifferentiated blood cells, and there is provided a method of introducing any gene for which transient expression in these cells is desired. In particular, the method is useful for intracellular DNA recombination by transiently expressing site-specific recombinase, and for induction into any cells of different lines by transient expression of master genes.
