  • Publication number: 20100259273
    Abstract: The present invention provides a cold cathode ionization vacuum gauge that can trigger discharge in a short time even in the case of use over a long period of time without needing a complicated apparatus. It has the structure in which a rod-like anode is located in an internal part of a measuring element container (cathode) having a discharge space with one end thereof which is sealed, and a discharge starting auxiliary electrode is mounted on this anode. The discharge starting auxiliary electrode triggers the discharge in a short time by the formation of a carbon nanotube layer on a discharge starting auxiliary electrode plate.

  • Patent number: 6809442
    Abstract: A stator for a rotary electric machine is provided to curb decreases in output caused by magnetic flux leakage. The stator has a stator core with stator coils that are wound around tooth parts of the stator core. The tooth parts of the stator core are arranged to form a rotational space with respect to a rotor, and housed inside the slots and cooling medium passages are formed inside the slots by blocking the openings of the slots. The protrusions are provided that protrude into the slots from both lateral surfaces of the tips of the tooth parts. The plates formed with grooves on both sides thereof that fit on the tips of the protrusions are arranged between adjacent ones of the protrusions so as to block the openings of the slots.

  • Patent number: 6713927
    Abstract: A rotating electric machine using an inner section of a slot of a stator as a cooling passage obtains highly effective cooling performance with a small amount of cooling medium. An opening for a slot in a stator is closed by an under plate having a closing member. A regulating plate is disposed which is a member for regulating the cross-sectional area of the passage in substantially a central section of the slot. In this manner, the cross-sectional area of the cooling passage with the plate in the slot is smaller than the cross-sectional area when the regulating plate is not provided by an area corresponding to the cross-sectional area of the regulating plate. This arrangement allows increases in cooling efficiency.

  • Patent number: 6703743
    Abstract: A motor or a generator which has permanent magnets on a moveable member effectively reduces eddy current loss in the permanent magnets. A permanent magnet 1 which is provided for the moveable member of a motor or a generator, for example the rotor of a rotating motor, is divided into magnet sections (1A-1E) having divided widths (t1-t5) in response to the rate of change in the flux density in each divided magnet. Thus the eddy current loss in each magnet section (1A-1E) can be substantially equalized.

  • Patent number: 6700283
    Abstract: This invention provides a rotating electric machine using an inner section of a slot of a stator as a cooling passage and allowing a high cooling efficiency. Furthermore, it provides a manufacture method for the rotating electric machine which allows streamlining of the manufacture of the cooling passage. A plate is attached to the plate retaining groove formed in proximity to the opening of the slot of the stator. A resin layer is formed by injection of resin into a space formed between the outer face of the plate and the mold set on an inner peripheral face of the stator. The plate is pressed by the injection pressure of the resin to come into close contact with the stopper and to create a seal which prevents leakage of resin into the slot. A leg is provided on the plate and extends into the slot for reducing the cross sectional surface area of the cooling passage.
