  • Patent number: 6182552
    Abstract: A holding device for a cage for roll bodies of longitudinal leaders on pillars of a tool, in particular a blanking or punching die or a mould, the tool consisting of a plurality of assembled plates, and having at least a first part and a second part. The holding device comprises a holding part which includes a hollow cylindrical rod, held displaceably in a longitudinal bore made on the free end of each pillar. Said rod is provided on its face with a disk projecting beyond the circumference of the pillar. Also inserted into the longitudinal bore is a screw. Provided on the shank of said screw is an elastic element over which an annular element, inserted into the hollow cylindrical rod, is pushed when the holding part is in pushed-in position. The elastic element holds the annular element in this position in a firmly clamping fashion.

  • Patent number: 6154921
    Abstract: This invention relates to a vacuum cleaner having a vacuum cleaner housing and a pivotable handle with a grip portion. The handle is pivotably secured to the vacuum cleaner housing in such a manner that the turning axis of the handle is generally horizontal and perpendicular to the direction of movement of the vacuum cleaner when the vacuum cleaner is in a working position on a horizontal surface. The handle is maintained in a generally vertical position when the vacuum cleaner is in the working position. When an operator lifts the vacuum cleaner housing from the working position using the handle, the vacuum cleaner housing pivots to a substantially vertical position, with the position of the grip portion relative to the operator's hand remaining substantially unchanged during the lifting.

  • Patent number: 6122973
    Abstract: A capacitance-type pressure sensor capable of reducing a variation in reference capacitance. The capacitance-type pressure sensor includes insulating spacer (3b) arranged between a main capacitive electrode (4) and a reference capacitive electrode (5) to couple a base substrate (1) and a diaphragm substrate (2) to each other. The insulating spacer (3b) is patterned so as to restrain a variation in distance between the reference capacitive electrode (5) and a counter electrode (10) arranged on the diaphragm substrate (2). Such construction reduces a variation in capacitance between the reference capacitive electrode (5) and the diaphragm electrode (10), to thereby increase accuracy at which a pressure is measured.

  • Patent number: 6121783
    Abstract: A needle is pressed into the backside oxide of a semiconductor wafer and a voltage applied to the wafer greater than the breakdown voltage of the oxide in order to make an electrical contact with the bulk material of the wafer. A capacitor plate is provided proximate to a wafer on a chuck and a Kelvin probe is provided proximate to the wafer. A varying voltage is applied between the chuck and the capacitor plate and a voltage is monitored between the Kelvin probe and the chuck. The monitored voltage remaining constant indicates electrical contact between the chuck and the wafer.

  • Patent number: 6116095
    Abstract: A method and apparatus for selectively predicting the air flows from a duct system that would be produced by environment conditioning plants. The apparatus includes a measurement duct connected to a blower. A restrictor plate is movably mounted over an inlet to the blower to vary the air flow produced by the blower so as to correspond to the air flow generated by a selected environment conditioning plant. A manometer is connected to the measurement duct and is operable to measure static pressure in the measurement duct when the measurement duct is in air flow communication with the duct system. Performance curves for the environment conditioning plants are used to convert static pressures to air flows.

  • Patent number: 6111390
    Abstract: A power device including a magneto and a rectification circuit for rectifying an output of the magneto is provided which is capable of adjusting an output of the magneto without any specific control circuit. A field adjusting excitation coil is arranged on a side of a stator of the magneto so as to generate a field adjusting magnetic flux when it is excited, resulting in a magnet field of the magneto being varied by means of the magnetic flux. The field adjusting excitation coil is connected to an intermediate portion of a current flow circuit for a load current, to thereby be excited by the load current, so that a magnet field of a rotor of the magneto is varied depending on the load current, leading to adjustment of an output of the magneto.
